Janja is a smoky gray spotted hyena with a grayish-beige underbelly. He has large ears that curve to a sharp point, with his left ear bearing a visible notch. His nose, feet, and the upper side of his tail are black. The under side of his tail is a beige color. His muzzle is gray. He also has dark gray spots across his back and a ridge of black fur running along his head and upper neck that juts back in sharp spikes. Janja's eyes are black, with thick eyebrows and a ring of darker gray fur around them.
Initially, Janja was a cruel, greedy, arrogant and villainous hyena who had no interest in protecting the Circle of Life. He was shown to care only for himself, always ordering others around to do his work for him. He thought only about getting food for himself and couldn't care less if the rest of his clan starved, though he did allow them to eat. Janja did frequently refer to the other members of his clan as "fur-brains", showing that he did not respect them. He insulted and mocked them frequently, but did not like being laughed at himself. He was ruthless and determined to eat as much food as he could.
Janja's intelligence is undeniable. He is a devious and manipulative planner who is always hatching new plots to defeat the Lion Guard or take over the Pride Lands. He is notably the only hyena in his clan who uses cunning to obtain what he wants. True to his name, Janja is very crafty and sly, though he sometimes has difficulty grasping simple concepts. However, his plots have yet to entirely succeed, due to the interference of the Guard and overlooked details. Janja also has a sense of humor and a fondness of witticism; he will occasionally make jokes and clever remarks.
Despite his ferocity and sharp intellect, Janja is somewhat of a coward, usually only choosing to fight when the odds are in his favor (when his clan has an advantage in numbers). He is also something of a sore loser in the face of defeat. Protective of his territory, he does not tolerate intruders and will attack those who invade his land. As shown in many episodes, Janja harbors a deep hatred for the Lion Guard, especially Kion and his Roar. He also has a strong dislike and disdain for jackals, believing them to be "annoying" and regarding their intelligence as inferior to that of his own species.
Since the beginning of the series, Janja has been shown to have deep admiration and respect for Scar. When a snake named Ushari informs him that it is possible to contact Scar, he immediately agrees to work together with Ushari to figure out how to do it, which they ultimately succeed in doing. Ever since Scar's return, Janja is shown to be respectful, but also highly fearful of Scar. He also appears somewhat threatened by Scar's new leadership over him and his clan, and asserts to his minions that they still have to listen to him, but still acknowledges Scar as their true boss for fear of stirring his wrath.
However, Janja proved to have at least some good in him in "The Hyena Resistance" when Jasiri saved his life. Rather then scorn her, he expressed great shock and confusion at why she helped him. Although Janja refuses her offer for him to join the Hyena Resistance, he hesitates for a moment leaving Jasiri feeling confident he will come around in time. This moment alone causes the skinks (who had been secretly watching) to question Janja's loyalty.
In "Battle for the Pride Lands", it is revealed that Janja and his clan are growing unhappy with constantly having to fight the Lion Guard to be able to eat what they want only to always lose and wind up hungry. Janja is also shown to be envious of how happy Jasiri and her clan are working with the Lion Guard. This causes Janja to begin to think that he should take Jasiri up on her previous offer to join her and that he is on the wrong side. After Janja attempts carry out another of Scar's plans to destroy the Lion Guard only to find that Scar was also planning to get rid of him and his clan for possibly betraying him, Janja realized that Scar never cared for him and finally switches sides. After Scar is defeated, Janja happily volunteers Jasiri as the new leader of the Outlands. He also displays a newfound respect for the Circle of Life and vows to stop any animal in the Outlands that tries to threaten it. He also looks to care about his clan and their safety.
Janja is shown to become kinder since his reformation, being one of the first animals along with Jasiri and Anga to show concern over Kion and Ono's injuries after defeating Scar. He has also become honest as he says Jasiri is the one that's worthy of leading the Outlands and not him.
Janja and his clan are starving in the Outlands. Cheezi notices a baobab fruit nearby and wants to eat it, but Janja is disgusted at the idea, and instead starts to chomp at a passing butterfly. He fails to catch it, and the other hyenas start to laugh as it lands on his ear. Janja snaps at them for this, though soon notices Bunga looking for his ball. Flicking the bone away, he orders Chungu and Cheezi to bring the honey badger over to him for his lunch.
Later, Mzingo hears of the new Lion Guard being formed and immediately alerts Janja, who shows great concern over this news as he remembers what the original Lion Guard stood for. He then comes up with a plan (after a brief interruption as he attempts to eat a nearby caterpillar) - to get rid of as many animals as they can to stop the new Lion Guard from being created. He leads his clan in the singing of the song Tonight We Strike to explain his plan to them.
At sunset, Janja and the rest of his clan then start an attack on the gazelles in their grazing spot, to which Kion is alerted to. Janja then fights the Lion Guard and sustains an injury, though eventually, he comes face to face with Kion himself. After taunting the lion cub, Kion lets loose the Roar of the Elders, and he and the other hyenas scatter back to the Outlands.
Janja, along with Cheezi and Chungu are seen attacking a herd of oryxes, but shortly thereafter The Lion Guard arrive on the scene. Kion orders the rest of the Lion Guard to calm the herd while he goes after Janja's clan. However during the pursuit, a log snaps under Kion's feet and he falls into a river, which sweeps him into the Outlands.
Later on, Janja and his clan confront a female hyena named Jasiri, who helped Kion escape the Outlands. She is able to easily fight off Cheezi and Chungu but is pinned down by Janja. Luckily, Kion returns and saves Jasiri by using the Roar of the Elders, which causes Janja to retreat, and both he and the rest of his clan scamper farther into the Outlands.
Mzingo arrives in the Outlands to inform Janja that Simba and Nala have left the Pride Lands and left their daughter, Kiara in charge during their absence. Janja soon realizes that he can use this to his advantage, and sends Mzingo to Pride Rock in order to offer a peace proposal on his behalf.
Mzingo does so, and although Kiara questions why Janja himself does not deliver the message personally, the vulture cooks up an excuse on his part, asking her to meet them at Broken Rock. After a fall out with her brother over Mzingo's proposal, Kiara makes her way to the Outlands, hoping to finally make peace with Janja. However, she soon realizes that something is wrong, and that she's made a mistake. As Janja, Cheezi and Chungu approach the queen, Janja announces his plan. With Kiara in his grasp, Simba will have no choice but to hand the Pride Lands over to them. The hyenas circle around Kiara, and a couple of them leap at her. Kiara's agility secures her victory, though this is short lived as Janja pins her down. Before he can do anything, Kion arrives, much to Kiara's surprise. This doesn't phase Janja, as his clan is up 6-2. Suddenly, the rest of the Lion Guard join Kion and Kiara, evening the odds. Janja makes a quick retreat, and his clan flees back into the depths of the Outlands. Kiara apologizes to her brother for not listening to him about trusting Janja. Janja overhears this and replies that he can hear them, just before he makes his leave.
Janja and his clan cause a wildebeest stampede at the beginning of the episode, causing dust to cloud the air as the Lion Guard tries to restore order and stop the hyenas. Janja sneaks up on Kion and prepares to take him down, but is quickly foiled by Ono, who alerts Kion of the hyena's presence. Janja and his clan are chased back into the Outlands. Janja learns of Ono's injured eye by word of Mwoga, one of Mzingo's affiliates. He plans to trap the Lion Guard in a rock slide and tells of his brilliant plan through the song Outta the Way. Much to his dismay, Cheezi and Chungu still don't understand the plan, but they decide to go along with it anyway. The hyenas form two rock piles to unleash on The Lion Guard, and after trapping them, are sure of their victory. However, Ono alerts the nearby zebra herd that Janja plans to attack to move away from the valley in which they are grazing. With the area clear, Kion is able to use the Roar of the Elders without hurting the herd, blasting the rocks out of the way and freeing the Guard. Janja is stunned to see that the Guard has escaped, and orders Cheezi and Chungu to flee.
Janja and his clan are seen chasing the young jackal pup, Dogo, who had trespassed into their den. Janja chases dog and prepares to pounce on him when he is stopped by Kion. Janja learns that the Pride Landers are celebrating Kupatana, so he lets Kion leave with dog, laughing and saying that "If you want the jackal, he's all yours." Janja and the hyenas then run back the way they came, with Janja yelling "Merry Kupatana!".
Janja is in the Outlands with the rest of his clan. He is being groomed by Chungu when Cheezi enters, bearing news of a new meal in the Outlands. Janja and the rest of the hyenas head out at once to capture Bunga, who has wandered into the Outlands. After surrounding the honey badger, the hyenas prepare to strike at him but are promptly stopped by Fuli. Fuli and Bunga begin floating downstream in the lava atop a piece of broken rock. The hyenas pursue them but are eventually stopped by the Lion Guard, who appear to save Fuli and Bunga. Janja, Cheezi, and Chungu find themselves trapped atop a burning log with no food at all.
Janja, Cheezi, and Chungu sneak into the Pride Lands. As Ono swoops over the Pride Lands, searching for them, they hide in a bush until he is gone. Janja steps out, noting that he doesn't think Ono saw them. When Chungu loudly complains to Cheezi, Janja warns him that Ono may be able to hear them. He corrects Cheezi's assumption that they call Ono the "Ears in the Sky" before sneaking away, Cheezi and Chungu following.
Later, as Shauku, Mtoto, Kwato, Kambuni, and Gumba chase hyraxes, Janja overhears one of the five shouting his name. He points out the young animals to Cheezi and Chungu, and the two make comments about eating them, laughing after they speak. Janja, Cheezi, and Chungu follow the kids as they play. When they call the hyenas' names, Chungu wonders if they are actually chasing them. Janja contradicts him, telling him that they're playing pretend, but that it is "about to get real".
The hyraxes eventually flee to safety, and Mtoto wonders what they should chase now. Janja answers him, suggesting they the hyenas chase them. The five friends flee in terror, and Janja chases after Mtoto. Mtoto manages to evade him by turning sharply as he nears a boulder, causing Janja to crash into it. Cheezi and Chungu approach him, they too have failed to catch one of the animals. Janja decides to pursue Mtoto, seeing as he is the slowest.
He, Cheezi, and Chungu corner Mtoto next to a wide river. Beshte suddenly jumps out of the water, scaring the hyena trio away. He swims down the river with Mtoto now on his back, and Janja, Cheezi, and Chungu follow. Cheezi and Janja wait for Mtoto to pass beneath them, but Mtoto ducks and they end up knocking into each other. Janja continues to try and chase Beshte and Mtoto, but the rest of the Lion Guard arrives. Bunga knocks Janja into the water, and the crocodiles begin to chase him.
Janja, Cheezi, and Chungu attack a herd of impalas. Janja calls out that they only want to invite them to dinner and adds that they'll be the main course, to the amusement of his companions. However, the Lion Guard arrives to stop them. Beshte stands in front of them, causing them to crash into his rear end. Chungu begins to tell the Guard about Janja's joke, but Janja silences him. Kion orders the hyenas to leave, and they run away, but soon pause to catch their breath. They hear Janja's voice telling someone that they look tasty and that he is going to eat them. Cheezi and Chungu at first think that it was Janja saying that he was going to eat one of them, but Janja corrects them. He explains that he didn't say anything, but that somebody did. He approaches the area from where he heard the sound of his voice and discovers Tamaa the drongo mimicking his voice to scare a four-striped grass mouse. He orders Cheezi and Chungu to grab Tamaa and decides that if Tamaa helps him with his new plan, the hyenas may not eat him at all.
Janja later instructs Tamaa to say what he told him to say but to sound as though he were Kion. Tamaa at first protests, but when Janja threatens him, he obliges, and orders the impalas into the Outlands through Kion's voice. The impalas eventually flee, and the trio of hyenas give chase. When they reach the Outlands, Janja pauses to laugh and declare that their dinner is being delivered, and Tamaa takes his chance to ask if he can go now. Janja denies his request, pointing out that Tamaa still could be useful to him. He, Cheezi, and Chungu resume pursuit of the impala herd, who soon reach a dead end. Janja marvels at how easy his plan worked and announces that they're never going to let Tamaa go before beginning to stalk the impalas.
However, he soon hears the voices of the Lion Guard, telling them that they're surrounded and that they should leave and let the impalas go. Janja is at first terrified, but when Cheezi speaks, he realizes that Cheezi is no longer holding Tamaa. He finds the drongo and says that he knows the Guard isn't there, but Kion arrives and pounces on him, pinning him to the ground. Janja tries to make an excuse for his actions before fleeing with Cheezi and Chungu further into the Outlands.
Janja's clan has once again snuck into the Pride Lands, this time to take down a herd of zebras. Janja, Cheezi, and Chungu watch from a hidden location as Ono lead the zebra herd to a safe grazing spot in the Pride Lands. Cheezi and Chungu ask Janja what they are going to do, and Janja replies that after Ono leaves, they will spook the zebras and then they will be theirs for the taking. They then proceed to the song Panic and Run.
After trailing Ono to the grazing ground, Cheezi and Chungu begin to grow impatient. Janja tells them to wait until he says go, but after much confusion, Chungu eventually darts out from behind the rock to chase the zebras and Cheezi follows him. Not wanting to be left by himself, Janja follows after them. Ono spots the hyenas and rushes back to tell the Guard.
When the Lion Guard arrives, Kion tells the members to go after Cheezi and Chungu and leave Janja to him. Kion pursues Janja as he chases a zebra. Kion climbs up on a tree to get a better view on how to best defeat Janja, when suddenly Bunga tackles him, making him fall off the tree directly on top of Janja. Meanwhile, the rest of the Guard has managed to stop Cheezi and Chungu who are now ready to retreat. Janja agrees, and the hyenas scamper away.
Janja, Cheezi, and Chungu are in the Outlands when they hear the sound of a young zebra braying, which got raws
their attention at once. The trio sight a herd of zebras and a gazelle as well as the young zebra, and Janja notes that they're a "snack pack". Cheezi points out that Bunga and Kion are with them, but Janja dismisses this, telling him that the Guard members will protect the baby while the older zebras merely panic and run, which will allow them to hunt them easily.
The three hyenas dash towards the zebras and Janja calls out that the zebras had better run. However,
they all circle around Muhimu and the baby zebra, and Kion declares that they won't make it easy for Janja. This doesn't phase the hyena leader, and he attacks. Kion tackles him and pins him to the ground, but Chungu sent flying by one of the zebras, collides with him and knocks Kion away, freeing Janja. He approaches the herd, but as he makes his way through, the baby zebra kicks away and sends him flying into Cheezi and Chungu. The hyenas flee, and Janja remarks that he doesn't like zebra anyway.
Janja, Cheezi, Chungu, Nne and Tano are near the Lion Guard, with Janja plotting to use the sticky mud to their advantage whilst they feast on some nearby Wildebeests. Janja, however, slips on the mud himself and comes face to face with the Lion Guard. His other clan members soon join him. Cheezi and Chungu start to embarrass Janja in front of the Guard, inadvertently explaining his plan to them instead of leaving with Janja. Kion sees through Janja's lies and uses the Roar of the Elders to blast them away back into the Outlands and Janja leaves annoyed. Soon after, he 'fires' Cheezi and Chungu. He promotes Nne and Tano to be his new crew members, banishing Cheezi and Chungu. Nne and Tano join in on Janja's command, scaring the two away.
They return to the Outlands, Janja explains the rules to his new henchman. He misses out rule number two, which slightly agitates Nne and Tano, forcing Janja to keep the rules short and simple - that he is the one who comes up with the plans. However, this time, Nne and Tano are able to concoct a brilliant scheme, whilst Janja is left confused. They plan to divert the Lion Guard by frightening away some antelopes one way and, whilst the Guard are busy dealing with them, feasting on some Oryxes the opposite way. Janja remains confused by the end of their explanation but decides to go along with it. They put the plan in action, with the antelope herd continuing to move in the direction of Rocky Plains with Janja, Nne, and Tano chasing them. They stop Janja after a while and hide him from the passing Lion Guard. When Janja questions their actions, Nne and Tano become annoyed at how poorly he listened to their plan. Janja wishes to eat the antelope, but Nne reminds them of their true goal - the oryxes. Nne and Tano runoff, mocking Janja. Janja swiftly chases after them.
Meanwhile, the three hyenas continue their chase, but Janja runs into a slumbering Cheezi and Chungu by mistake. They are overjoyed to see their leader, but Janja refuses to pay them attention and continues chasing after Nne and Tano instead. The three hyenas continue their chase, but Janja runs into a slumbering Cheezi and Chungu by mistake. They are overjoyed to see their leader, but Janja refuses to pay them attention and continues chasing after Nne and Tano instead. Cheezi and Chungu decide that it must have been a dream, and they quickly go back to sleep to dream about Janja again, whilst the real Janja catches up to his new crew. Nne and Tano are disappointed to see him, and Janja is shocked when they announce that they were trying to ditch him. Tano then pushes Janja over a nearby cliff, where he falls on a mud-covered rock. The two hyenas race away to the oryxes, abandoning their former leader. Janja calls up from his location, but the Lion Guard manage to find Janja before anyone else, along with Cheezi and Chungu who had followed them. He is furious at the betrayal of his new team members but equally disappointed to see the Lion Guard. He gladly spills the beans and explains what they were up to, and the Lion Guard rush off. Soon after, Cheezi and Chungu leap down to keep Janja company, much to his annoyance. <p>
When Kion uses the Roar of the Elders to defeat his former henchmen, Janja comments that, for the first time ever, he is glad to hear the roar. The rock then breaks away, causing the hyena trio to fall all the way down. The Lion Guard decide to help the hyenas, only to find them on the ground with a clear pathway back to the Outlands. Kion calls for them to leave, and Janja does so, calling for Cheezi and Chungu to join them. With elation, they race after their leader.
Janja and his clan are driven out of the Pride Lands for what Janja claims was "just one gazelle." They flee back to the Outlands, but Janja is quick to head back into the Pride Lands, wanting to get the gazelle. He dismisses Cheezi and Chungu's worries, reminding them that they don't listen to the Lion Guard. As they make their way into the forbidden territory, Janja declares that he'll go into the Pride Lands if he wants to. Nala appears and inquires what he's doing in the Pride Lands, causing Janja to mockingly fake innocence. Nala gestures in the direction of the Outlands and orders them to go, but Janja does not back down, instead of telling his clan that Nala isn't so tough alone and outnumbered. Though she is not afraid, he attacks her. He's advancing on her when Kion finds out what is going on. In a fury, the cub releases the Roar of the Elders, forcefully sweeping the hyenas back into the Outlands, dazed.
Janja, Cheezi, and Chungu approach a cliff-side where a group of Klipspringers is stranded. As they get close, Ono calls out to them. Upon noticing the egret is alone, Janja merely snickers, telling his henchmen to ignore them due to this fact. Ono warns them that he'll be performing the 'Hadithi Spin' which confuses Janja. After a few loops, the egret crashes into another part of the cliff. While Cheezi and Chungu run after him, Janja decides to round up the main course.
Before Janja can reach the klipspringers, Kion and Bunga appear behind him, warning him away from them. When they point out that they're behind him and the only way out, he tells him that he doesn't care since there's so much to eat just in front of him. Kion then calls to Beshte, who pushes a large boulder across the chasm, while Fuli arrives to guide them across. Janja rushes forward but his two henchmen fall onto him from above. He ignores their excuses and calls for them to follow.
When they start to cross the chasm, Ono and an eagle appear, swooping around them. When Janja hears Ono refer to the eagle as Hadithi, Janja stutters worriedly. While Ono continues swooping around, Cheezi comments that he's going to lose his lunch, and Janja angrily admits that they all are before falling into the water below. When Cheezi questions who the eagle was, Janja becomes annoyed at his henchmen for not knowing who Hadithi the legendary eagle is. When they become excited at being beaten by a legend, Janja grunts irritably as the current take them downstream.
Janja discovers Mwevi and Mwizi in his den, trying to steal food from him. He chases them out, only to find Cheezi and Chungu getting entertained by their leader, Uroho. He orders them to catch it, but the two hyenas are too amused by his jokes. After Janja reminds them that his food, they soon comply, and the six wind up in a large open space. Despite his best attempts, Janja is unable to capture any of the baboons, and his cohorts end up dizzy.
But when Uroho accidentally guides his friends into a dead end cave, Janja, Cheezi, and Chungu seal them in. Before they can attack, the Lion Guard arrive, demanding that they step away from them. Janja protests, explaining how he caught them stealing food from the den, but the Guard attack regardless. The hyenas try to fight back but are quickly defeated by the Lion Guard. Janja then retreats, warning the baboons to stay out of his den in the future.
During the song Fujo, Janja is attacking Laini and her group until he is stopped by Kion. Then, he leads his clan in an attack on Ma Tembo's Herd. Nne asks Janja if he's sure about this and he replies with a positive answer since elephants are nice and tender this time of year, especially young ones. He and Nne close in on Mtoto, but one of the herd's members send them flying. Janja and his clan continue the attack until the Lion Guard arrives. He keeps running until Kion jumps right in front of him freezing the hyena in his tracks. Janja introduces Nne to Kion so he can make his getaway and meets up with the rest of his clan after the guard chases them out of the herd, and then Beshte sends them flying.
Janja ends up landing on Ushari and retreats with his clan. He then rallies up another attack against the elephants and this time including the baboons too; they chase the baboons and elephants to a dead end (which is actually the Lion Guard's plan) and are driven away by Kion's roar and retreat to the Outlands.
Back in the Outlands, the hyenas notice Ushari slithering around. When Chungu asks his leader if they can eat it, Janja replies unenthusiastically that they can, still disappointed with their earlier fails. Before they feast, Ushari starts to talk about how Kion gets his advice from Mufasa. Although hesitant to believe him, Janja starts to warm up to the snake after he mentions the possibility of speaking with Scar. Janja agrees to let him gather information, but they will be following him, just in case.
Janja watches Ushari speak with Rafiki's apprentice, Makini, who confirms the ability to speak with Mufasa. After planting the idea of speaking with Scar in her head, Ushari returns to Janja, who heard everything. Stunned, he agrees to seek out more information. With Janja Still wary of Ushari, the snake brings him some friends of his, a group of skinks. Shupavu sends out Nyeusi to see where they're going. He follows them to the entrance of the Lair of the Lion Guard and slithers back to tell the others of his findings.
Back at the Outlands volcano, Ushari discusses the latest information with Janja's clan and continues to explain how they need a Bakora Staff and for Kion to use his Roar of the Elders. They eventually decide that Kion roars best when his loved ones are in danger, and, with their goal in sight, they decide to Bring Back a Legend. Ushari waits in the volcano, while the hyenas get a staff and a loved one to lure Kion in. As they leave, the hyenas trample Ushari.
The hyenas enter the Pride Lands and ambush Makini and Kiara, grabbing Kiara and the mandrill's staff and taking them back to the Outlands, where Kiara is thrown into an area full of geysers. Janja waits until he hears Kion, ordering his hyenas to entertain their guests while he deals with the cub.
Janja tries to get Kion to Roar, but the cub refuses. Janja then states that they have demands, trying to keep the cub's attention. After exchanging some words, Ono swoops down to Kion and informs him that Kiara has been saved. With Kion about to leave, Janja taunts Kion, saying that they'll keep coming back again and again to harm Kion's family and that there's nothing he can do to stop them. In a fit of anger, Kion unleashes the Roar of the Elders, causing the volcano to erupt.
With the volcano erupting, Janja returns to the volcano, where Ushari is not having any luck in summoning Scar. In a fit of fury, the hyena grabs the staff from the cobra and throws it into the lava below. Suddenly, an entity rises from the volcano, laughing menacingly. Janja draws back and stutters and, before he can ask, the entity confirms that he is indeed Scar.
In the volcano, Janja reminds Cheezi and Chungu that even though Scar is their boss, they are to listen to what he says over anyone else, whilst. Whilst Cheezi understands Chungu fails to grasp it. Just then, Njano arrives and informs him that Beshte is alone in the Outlands. Janja dismisses it, then Scar appears and states that it's the perfect time to eliminate him. Suddenly, Janja's becomes interested in the situation. When Chungu asks his boss how they're going to take out Beshte, Janja warns him against being called 'boss' in front of their current boss, Scar. He then orders his hyenas to listen to Scar, who has a plan.
When the plan begins, Janja watches the skinks lure Beshte into a canyon below Rocky Plateau. Cheezi comments that his plans don't usually work out and Janja reminds him that this is Scar's plan. Cheezi cheers up, believing that the plan might work this time around. Janja agrees but soon becomes angry at what his clan member is saying about his own plans. They reach the top and start to push rocks onto the ground, trapping Beshte in a small area. They continue pushing rocks, trying to squash the hippo. When he's almost out of room to dodge, Janja, Cheezi, and Chungu start to push a very large boulder that they had been saving for last. But the Lion Guard arrive just in time to save their team member, with Fuli stopping the rock from falling. Kion orders Janja to back away, and Janja claims not to have known the hippo was a member of the Lion Guard and that they were just having some fun, but Kion sees through his thinly veiled lie. When Janja gets close to the edge, Kion uses his Roar of the Elders to send the hyenas flying. When they fall, the hyenas know that Scar will be mad with them. Janja suggests that they don't have to return right away, but Ushari is waiting nearby, telling them that Scar wishes to see him. And he's not happy to which Janja responds "Oh boy..."
Janja, Cheezi, and Chungu are looking for the jackals with hopes of persuading to join Scar's side. Jasiri stops them and mocks Janja for not marking his turf for the Dry Season. This angers Janja, causing him to attack Jasiri. She successfully fends off the attack, forcing Janja and his henchmen to retreat. Janja, Cheezi, and Chungu return to the volcano, and after Ushari asks how it went, they tell Ushari of the fight with Jasiri. Ushari is surprised to hear that only one hyena was able to defeat all three of them, but Janja states Jasiri is not ordinary hyena and that "She's fearless or something". Suddenly Scar appears and suggests adding her to their "Collective". Janja argues, telling him that she's The Worst Hyena We Know, and of her friendship with the Lion Guard, and love for the Circle of Life. Scar now sees Jasiri as a threat and tasks Janja to use all of his clan to remove her from the Outlands.
Later, Janja observes Jasiri playing with Wema and Tunu. He orders his clan to get into position and launches his attack. Jasiri manages to fight off several hyenas and reunites with the two cubs just as Janja knocks her and them into a large steam vent. A delighted Janja then explains to his clan that the rising steam indicates that the vent will soon explode. Janja decides to stay and watch Jasiri die, mocking her the whole time. However, the Lion Guard later arrives to stop them. Janja taunts the Lion Guard, bragging about his clans' strength in numbers. Janja and Kion charge at each other as a large battle ensues. One by one, all of Janja's clan are defeated by Lion Guard. As Janja and Kion fight, Janja's tail is burnt by the steam vent. He then drags his tail across the ground in a humorous attempt to stop the pain. Soon Janja and his clan regroup for a counter-attack but are again defeated. Fuli knocks Janja back as the rest of his clan retreats, leaving him alone (Except for Cheezi, and Chungu who are still distracted by Thurston). Despite this, Janja considers himself victorious, as Jasiri is nowhere in sight. However, she then appears safe and sound riding a large slab rock to the top of the steam vent with Wema and Tunu. He is taunted one final time by Jasiri before he himself retreats along with Cheezi and Chungu.
Having found a patch of Tikiti Melons, Janja orders Cheezi and Chungu to steal them. However, the Lion Guard arrive, causing Janja to sarcastically tell them that they'll return them once they've drunk the water from them. The Guard leap into action, with Kion reclaiming the melon from Janja. Defeated, they return to the Outlands. At the volcano, they trip over Ushari, and their arguing awakens Scar. When Janja explains what they were trying to do, Scar has a plan to steal the melons. Janja reminds him of the Lion Guard, and Ushari tells them about his friend, "Big Bad Kenge". He warns them not to call him little.
Back in the Pride Lands, the hyenas meet up with Kenge, and Janja announces that he's definitely not little. The word "little" grabs Kenge's attention, and Janja assures him that he's a big lizard. With hostility, Kenge tells them not to forget it. When they ask how they're going to find the Guard, Kenge announces that he'll let them find him instead. He causes a scuffle with the hyenas watching nearby. Sure enough, the Lion Guard arrive and engage in combat with Kenge. The monitor lizard bites Kion, Fuli, and Beshte, before being scared away by Bunga's flatulence. The hyenas chase after him.
With most of the Guard down, they return to the patch, where the hyenas gather up the melons. Janja turns to Kenge, asking for a "little" help. He quickly changes his wording to some "big" help, before Kenge asks him if he thinks Janja's in charge. Although Cheezi and Chungu say that he is, Kenge asserts his role as leader. But before they leave, Bunga and Ono arrive. Kenge orders the hyenas to return with the melons, but Ono and Bunga stop them from doing so. After Kenge bites both Bunga and Ono, they continue with their theft, with Janja commenting on how the plan worked out. Kenge merely replies that it was the plan. As they move through Embamba Canyon, they halt movement when Bunga arrives. Confused as to why he isn't paralyzed, they abandon the melons to confront him, not noticing Makini behind them. They grow worried when Bunga starts to taunt Kenge on his size, eventually forcing him into a rage-filled frenzy. After luring Kenge into biting Cheezi and Chungu, Bunga circles around Janja, worrying him. Janja picks Bunga up in his mouth, but as Kenge lures in to eat him, Makini throws a melon at his head, causing Kenge to bite Janja's leg instead. With all three hyenas paralyzed, they're unable to move when The Lion Guard arrive. When asked if he's going to tell them to run, Janja states that if he could, he would. Kion uses the Roar of the Elders, and the hyenas, plus Kenge, are sent back to the Outlands.
Janja, Cheezi, and Chungu are lurking in a bush, waiting for Zazu to arrive. Having been told by Scar to grab him, they wait for the bird to swoop down in a clearing before pouncing. Chungu grabs the bird in his mouth and takes him back to the Outlands. In the Outlands, Cheezi, and Chungu keep watch on Zazu, while Janja speaks with Scar in the volcano, asking what to do next. Scar orders Janja to interrogate Zazu, who will have all the information on Simba, including his strengths, his weaknesses, and his allies. Janja is confident that he can get Zazu to talk, and leaves the volcano to proceed with the plan. <p> Zazu tries to persuade Cheezi and Chungu into letting him free, but Janja arrives to put a stop to his plan. He orders Zazu to talk, but the hornbill is left unintimidated by the trio. When the rest of Janja's clan arrive, Zazu feigns defeat, before crying out at the top of his voice for help. Annoyed, Janja rolls the cage to the steam vent, prompting Zazu to finally give in. He opens up to them about Simba, but none of the information is helpful to the hyenas. But in the distance, his singing is overheard by the Lion Guard. When he finishes, the information is of no use to the hyenas and they decide to eat him instead, letting the steam warm him up. But the Lion Guard arrive just in time and start to fight Janja's Clan, with Janja taking on Kion. He has quickly pushed aside when Kion notices Zazu in danger. When the hornbill is saved, Janja calls for his clan to retreat, angry that they received no important information.
Janja's clan are in the Pride Lands, chasing Twiga and Juhudi with the Lion Guard hot on their trail. He shows no concern, and the Lion Guard soon split up to stop Reirei's Pack elsewhere, while Kion and Beshte continuing chasing Janja and his clan. Janja notices the pair gaining on them and orders Nne and Tano to deal with them. They are effortlessly knocked over by Kion and Beshte, prompting Janja to send out Cheezi and Chungu as well, just as Nne and Tano get back up. With Janja getting closer to the giraffes, Twiga takes action and kicks him away. Despite outnumbering Kion and Beshte, Janja picks himself up and calls for his clan to retreat. They meet up with Reirei's pack in the Outlands and return to Scar, explaining how their plan to split up the Lion Guard worked so well. Scar reveals that their first mission was merely a test and that their main objective would be in the next mission - eliminating Rafiki. When Janja and Reirei show confusion at this plan, referring Rafiki as "An old monkey", Scar continues to inform them that Rafiki can sense all the Lions of the Past, including himself, something he does not want the Pride Landers to discover yet. Janja and Reirei then start to squabble over who will take out Rafiki and who will cause a distraction, but Scar grows tired of their pettiness, and sends Janja's clan out to take down Rafiki, who he informs them is meditating at Mapango Cliffs. Outside, Janja taunts Reirei over Scar's decision. When Reirei states that jackals are the smartest, Janja argues with her over that statement. As Rafiki meditates on a rock, Janja's clan start to move in. When a fireball starts a blaze nearby, Cheezi begins to panic, only for Janja to tell him that it's all part of Scar's plan. When the hyenas surround the mandrill and Janja calls for them to attack, however, Rafiki performs some unexpected martial art tricks on the hyenas, defeating them with ease. In the distance, Janja notices the entire Lion Guard approaching, and comments on how their mission is not going as planned. The Lion Guard take over from Rafiki, continuing to defeat the hyenas with little effort. Janja retreats into the growing fire, but before he can leave, Scar appears in the fire, ordering Janja to finish the job. Janja expresses his concerns over being outnumbered, but Scar responds with 'not for long'. Janja exits the flames to see Reirei's pack have arrived and gladly joins up with everyone. The hyenas and jackals fight together, and Janja comes very close to defeating Kion, but the distraction of Tamaa the Drongo allows Kion to overpower Janja. The hyenas and jackals surrender and are still sent home by the Lion Guard.
In the Outlands Volcano, Janja, Ushari, Reirei, Kiburi, and Mzingo have gathered for a meeting with Scar. When their leader orders his next plan for Simba and the Guard Janja asks how they will take down Simba and the Guard on the same day. Scar explains that the scorpion named Sumu will help take care of Simba. As Sumu enters Janja first jumps on top of Reirei, then Kiburi, panicking. After Sumu has left, Janja asks Kiburi if Sumu is gone. Kiburi answers 'yes' before throwing Janja off his back.
As per Scar's orders, Janja and the rest of his clan lie in wait outside. When the now exhausted Lion Guard make their way up the Outlands Volcano searching for the antidote for Sumu's sting, Janja's clan ambushes the Guard and engage in combat. Janja immediately pins Kion down but is thrown off when Cheezi and Chungu are catapulted across to him. Later, once the Lion Guard have been introduced to Scar, Janja and the rest of the newly formed Army of Scar approach the Lion Guard, cornering them over the volcano. Kion uses the Roar of the Elders to force some of the army away, causing Janja's clan to take their turn. But like those before them, they are left defeated back in the volcano when Kion uses his Roar again.
Under Scar's orders, Janja and many members of the Army of Scar set Kilio Valley on fire and ambush Ma Tembo's Herd while the Lion Guard try desperately to extinguish the flames. Janja approaches Mtoto but is tackled by Bunga before he can cause harm to him. Outnumbered and unable to keep up with the fire, the Lion Guard have no choice but to retreat, leading the elephants away from Kilio Valley and leaving the valley to Scar's army, who watch them deviously.
After he and the other villains successfully take over the valley, Janja states that it was only thanks to the hyenas that they were successful, sparking off a debate between the leaders over who was the most helpful in the battle. Scar appears after Mwoga drops an ember and congratulates them for winning, and proceeds to tell them to stay in the valley, explaining to him and the others it’s all part of his plan to take over the Pridelands piece by piece. It isn't long before everyone agrees that the place is a dump, except for Goigoi, who finds it cozy. Janja decides to appoint himself the leader, which arouses anger from the other animal groups. Refusing a parliamentary procedure as stated by Mzingo, Janja starts to tell everyone that he'll run the dump. Reirei states that she'll be the one to run the dump, followed by Mzingo, who wishes to run it democratically. They turn to Kiburi, who refuses to sing, and then continue to argue with each other. Later, Ono notices the army fighting between each other, with Janja attacking Kiburi.
Janja returns to the Outlands to hear of Scar's new plan, but he is immediately chastised by Ushari for being late. When the pair starts to argue, Scar appears, stating that he has no time for ridiculous arguments. Janja tries to pin the blame on Ushari, but Scar refuses to listen and explains his latest plan. He orders Janja to take his clan and drop rocks in the top part of Hakuna Matata Falls at night to block the river from flowing. Janja questions why and Ushari explains that it will cut off major water supply during the dry season. Janja is still a little uncertain, but takes his clan and leaves the Outlands.
That night at Hakuna Matata Falls, Janja and his clan start pushing the rocks into the river as instructed. He orders Cheezi and Chungu to begin by pushing the largest rock when they start commenting on the rock's texture. He asks what they're doing when a familiar voice speaks, leaving him wondering who it was. When Cheezi and Chungu run past, the voice speaks again, and this time, Janja recognizes the voice. When Kion reveals himself from some logs, he catches up to Cheezi and Chungu. When Cheezi questions where they came from, Kinyonga appears to tell them that they learned it from her. Startled by the chameleon, the trio runs into the river to escape.
After getting out of the water, Janja decides not to tell Scar about their defeat by the Lion Guard, and blame it on some foliage and rocks. Kion peers down at them from above and orders them to leave and they do as instructed.
Janja, Cheezi, Chungu and Kiburi and his float try to attack the Lion Guard. After being beaten they flee to the Outlands. Later on, Janja tells his clan about the new plan from Scar, which is a three-sided attack. Jasiri's Hyena Resistance overhear it, and push a rock down the canyon and make a rock slide. Janja tries to climb up and over the rock slide but takes a rock who makes him fall and slide down. Angrily he and his clan go back to the volcano. When Janja is so soon back, Scar assumes he has defeated the Lion Guard easily. Janja then tells him that there was a rock slide and they didn't make it to the Pride Lands. Scar becomes angry and roars at Janja which knocks him backward. Kiburi and Reirei come back from their attack, and Kiburi blames Janja for not showing up. Janja gets his ears down and tells Scar that it only was bad luck. Scar then gives Janja and the others another chance, but with Kiburi as the leader. When Kiburi messes up, Scar angrily puts Reirei in charge. Reirei messes up too and Scar becomes very angry. The skinks come to inform Scar that Jasiri and her Hyena Resistance are working with the Lion Guard and that They're behind the Army's latest failures. Scar asks Janja if he missed a detail when he told that he took care of Jasiri, Wema, and Tunu. Janja fearfully tells him that The Lion Guard came in and saved them. Scar becomes angry but gives Janja one more chance. After telling the plan to him, Scar coldly orders Janja not to fail him again. When Janja's clan, Kiburi's float, and Reirei's pack surround the Hyena Resistance, the Lion Guard comes to the rescue. While Janja is about to attack Jasiri, a crocodile who is after Fuli, hits Janja instead of Fuli, making him fall into a steam vent.
When Kion has roared the others away, Jasiri hears Janja asking for help. She runs over to the steam vent and sees Janja sliding down toward the lava. Jasiri doesn't hesitate and bites into Janja's mane and pulls him up. Janja, shocked and confused, asks why Jasiri helped him. Jasiri mentions that she'd help any hyena, telling him they're the same by saying Sisi ni sawa. She then suggests Janja should leave Scar and join the Hyena Resistance to help defeat him. Janja hesitates, but ultimately refuses and runs away saying that he and Jasiri aren't the same. Despite his refusal, Jasiri just smiles, remaining hopeful he'll come around. Unknown to the hyenas, the skinks saw what happened, and begin to doubt his loyalty so they decide to report Scar.
Janja, Cheezi, Chungu, Reirei, Goigoi, Kiburi, and Tamka are sent by Scar to attack Basi's Pod and Big Springs. Shujaa takes a tree branch and starts running after Janja, Cheezi, and Chungu. Janja orders them to run, but Shujaa hits them and they go flying away. However, after Scar hears how they got beat by a huge gorilla he gets mad. Janja tells him how Shujaa ripped up trees and threw boulders at them. Scar then comes up with a plan. He orders his army to keep attacking the Pride Lands. That way Shujaa can mess of the Pride Lands for them and do more damage than they could ever do. Scar's army goes back to the Pride Lands and starts sneaking up on some Sable Antelope. Shujaa tries to help by making a path through Nyani Grove, but he starts knocking down trees. The baboons start to run towards the buffaloes Kion orders Fuli and Beshte to go after them.
Janja could see that Scar is right, by saying Shujaa is a menace. Kion uses his roar to blow Janja and the others away. Later they come back to Big Springs and this time there is a fire. Janja is attacking Kion. Ono goes to get Beshte but Beshte's leg gets hurt from a tree falling on it. Shujaa comes to save Beshte and scares off the crocodiles, jackals, and hyenas.
Janja is in the volcano listening to Scar's new plan. He then later goes to Makuu's Watering Hole and threatens to be nice to him, before they kick him out of his watering hole. Kiburi then comes and fights Makuu. Janja watches them fight until later goes to fight. He jumps on to Makuu's tail, holding him down. Ma Tembo then comes running towards them, doing her reverse-reverse trunk whip, which knocks Janja away. He then lands on Kiburi and then they spin a bit and gets knocked off Kiburi and watches Makuu pounce on Kiburi. He then shouts that all the Outlanders should regroup on higher ground. He thinks he got them, just as Kion uses the roar and blasts them back to the Outlands.
Scar orders the army to ruin the celebration that's at Mizimu Grove. However once again Kion has gathered the Pride Landers to fight them. Soon Scar reveals himself in front of everyone and scares the Pride Landers away. Kion uses the roar on the Outlanders and they are blasted back to the Outlands.
Janja sits on a rock in the still torched Kilio Valley, talking to Cheezi and Chungu. They mention that Kion has been growing up and his roar is now more powerful than ever. Janja blows them off and begins to walk away while thinking that they might be on the wrong side and begins to sing A New Way to Go.
Later, he is in the volcano, where Scar has summoned him. Scar knows about Janja thinking of leaving him. Therefore, Scar asks him to distract The Lion Guard in their own lair, while Scar fulfills the rest of his plan. Janja, thinking that he only has to distract the Guard, agrees. Janja heads into The Pride Lands feeling pretty good about it. He laughs so that the Guard will notice him and his teammates. He then lures them into the lair and run around so that the Guard won't catch them and kick their tails. They proceed with the plan, suddenly realizing a fire in the entrance of the lair that has been made by Scar's other followers. Janja is in shock and jumps trough the fire before it gets too big. Then he sees that his clan couldn't make it trough and are still stuck inside the lair. Janja figures out that Scar gave him the plan to distract him and his clan so that Scar could get rid of them. He is angry, but knows just what to do and rushes into The Outlands to get Jasiri.
He comes to her and says that he has thought about what she said about being the same, and tells her that the Guard and his own clan are stuck inside the lair. Jasiri rushes away with Janja to save them.
When they come back, The Guard already has gotten themselves and Janja's Clan out of the lair through Beshte's pool. Though the Pridelanders are having trouble trusting him. They eventually agree after encouragment from Makuu and Janja then tells King Simba that Scar revealed to him that only Kion can destroy Scar by using the most powerful roar he has into the volcano before they get some rest before the big battle. However, Scar reveals to Ushari that he deceived Janja, knowing he would turn on him and that using his most powerful roar in the volcano would cause a giant eruption that would destroy the Pride Lands rather then Scar.
The next morning they all go to the Outlands to defeat Scar once and for all. They run to the Outlands, where they meet the Army of Scar that now sees that Janja has left them. The Outlanders of course get beaten up by Pride Landers and The Lion Guard goes to the volcano to get Scar out of the way. During the battle, Cheezi and Chungu briefly forget their new alligance to the Pride Lands and almost attack the rhinos. This causes Janja to angrily tackle them and remind them they are on the Pride Landers side now before apoligizing to the rhinos and continuing the fight.
When they come out again, Kion goes onto a rock and announces, that Scar has been defeated. Everyone is very happy, but then Cheezi asks who will lead the Outlands so that there will be peace. Janja comes onto the rock and says that he found the perfect to lead. Kiburi dissapointedly asks if Janja himself wants to lead. Janja answers that he is not that dumb, but Jasiri should lead. Kion likes the idea and she is now the leader of the outlands. Janja replys, that all the hyenas will help, even his clan. Kion goes to see Rafiki because his scar is bugging him. Jasiri kindly says that he should go and Janja gives Kion a sad look as he leaves.
Anga remembers a time when they were all younger. Fuli comes up to Kion, Beshte and Bunga saying that a hyena has stolen an egg. Turns out that hyena is Janja. Janja is trying to steal an egg with Cheezi and Chungu. They all try to stop the hyenas and take the egg back.
Jasiri and Janja comes to the Tree of Life with Azaad. Bunga forgot that Janja was on their side and attacks him. Kion asks why they're here. Jasiri explains that Zira and her pride have returned. Jasiri is worried about Kovu and Vitani being growned up. Kion decides to go back home to the Pride Lands. Kion says to Rani that they have to go back home. Makini says that she needs to stay at the Tree of Life since she's Queen Rani's Royal Mjuzi. Rani says that Kion and his friends will always be welcomed at the Tree of Life. Kion thanks Jasiri for coming to get the guard. She says that she's returning the favor. Kion asks Ono if he still remembers all of the moja kwa moja stone's on Rafiki's map. Anga finds the lake and Kion says they'll need to move fast. Azaad finds a short cut to get around lake. Beshte wouldn't be able to fit through the cannyon. Kion uses the Roar of the Elders to make it bigger. It brings them to a ravine Kion uses the roar to send Bunga across. Janja starts to panic and Kion uses the roar on Jasiri and Janja. Janja was happy that was the best time Kion used the roar on him. Kion soon uses the roar to make it rain and get a log. They hop on the log and goes down the river. Kion keeps finding new ways to use the roar to get home faster. Azaad takes them to the Great Stone Wall he says the wall is too large to climb. Kion uses the roar again to blast a hole through the wall. Anga spots that the Great Stone wall is holding back a lake. She tells Kion to stop roaring however he doesn't and water comes through. Kion pushes the water back up. Anga soon spots hyraxes and klipspringer's. Fuli orders Beshte and Ono to fix the rock wall while Bunga and Anga take care of the hyraxes. Jasiri, Janja, Fuli and Azaad help the klipspringers get to safety. Jasiri tells Janja to keep the klipspringers running in one direction. They all save the animals and they go back to help Kion, Beshte and Ono. They soon make it around the Great Stone and back to the Outlands.
While walking through the Outlands Madoa, Cheezi and Chungu come by Madoa explains that they don't know what happened to Zira and her Outlanders cause they were hidding. Mzingo and his vultures comes by. Mzingo calls Jasiri Prime Minister and welcomes them back. Jasiri asks Mzingo if he will help Kion make peace in the Pride Lands. Mzingo says they will and Kion thanks them. Anga soon spots a strange lion on Pride Rock. Jasiri explains that it's KovuZira's son. Vitani's Lion Guard soon comes to the Outlands and starts attacking. After having enough Kion decides to use the roar on Vitani but Kiara stops them. Kiara explains that Kovu and Vitani has joined their pride. Vitani soon notices Kion and says that he looks different with that scar. Kovu explains that Zira has completed her journey through the Circle of Life. Kiara tells Kion to go to Pride Rock. Kion thanks Jasiri and Jasiri says if they ever need help they know where to find them. She leaves with the hyenas and vultures. Jasiri and the hyenas come to Kion and Rani's wedding. She watches as Kion becomes king of the Tree of Life.
Janja, Cheezi, and Chungu are in the Pride Lands. When the Lion Guard spot them, Janja announces that they should scram. They run into a large canyon, where they fool the Lion Guard into getting lost inside. The Lion Guard are able to escape the maze though, and Janja orders his henchmen to go after them. They all go different ways and soon realize that they have gotten themselves lost in their own trap.
Janja, Cheezi and Chungu kidnap Timon and Pumbaa when they wander too close to the Outlands. Although Chungu is worried that they are friends with the Lion Guard, Janja does not care.
If the Guard choose Bunga's route, they find Janja, Cheezi and Chungu fast asleep having taken a nap along the way back home. The Guard use Termites to break open a thorn cage that they have placed the duo in and, when they awake, the bugs bite Janja's nose.
If the Guard choose Ono's route, Janja leaves his prisoners on a rock surrounded by lava in the Outlands. The Guard are able to save Timon and Pumbaa by getting Beshte to push some rocks into the lava, redirecting the flow. Janja arrives to discover that the lava flow has been redirected to his own lair.
Janja and his crew go on a night hunt in the Pride Lands until the Lion Guard enters the scene thanks to a little bat alerting them. During the chase, Janja is alerted by one of his clan members that Cheezi and Chungu ended separated from them and decided to use that to their advantage. While the guard was chasing them, Cheezi and Chungu would bring something back. As Janja waits for them at the border between the Pride Lands and the Outlands, he begins to get annoyed that his two members haven't arrived yet. Until, the two come sliding down from the cliffs right into him; upset at another failed plan Janja calls them useless and returns to the Outlands.
Janja and his clan are descendants of Shenzi, Banzai, and Ed, and the hyenas from the original film. as stated in a promotional Disney Junior video.
In Rescue in the Outlands, Janja smiles with a somewhat dreamy expression when he says that Jasiri is fearless. This has led some fans to believe that he is romantically interested in her, which Ford Riley seems to confirm, stating that Janja is very confused about his feelings for Jasiri, despite his hatred for her good nature and beliefs. In addition to this, many of Janja's interactions with Jasiri can be interpreted as wanting to impress her (e.g. "Lemme show you how a real hyena fights"), and Janja hesitates when Jasiri offers for him to join her Hyena Resistance. In Battle for the Pride Lands, it is revealed that Janja has been thinking about Jasiri’s “Sisi ni sawa” philosophy, and when he finally realizes that Scar does not care for him, he immediately runs to Jasiri for help saving his clan. Later, he comments “I could get used to [her] laugh”, and does not hesitate to volunteer her to run the Outlands in place of Scar.
Janja and Cheezi are the only members of their clan who resemble the main hyenas from the original Lion King movie. Janja looks similar to Banzai and Cheezi looks similar to Ed.
A popular fan theory is that Janja is the son of Shenzi and Banzai, however, there is no proof of this theory being valid. Likewise, is no proof that this theory is false.
Along with the above, Janja is the leader of his clan, despite females usually leading a hyena clan, such as Shenzi from the original film, and Jasiri. Although there were shown to be no female hyenas in the clan so it's likely that Janja was a last resort.
However, after Battle for the Pride Lands, Janja likely revokes the leadership of his clan and submits to Jasiri's clan, making the clan similarly formed to real-life hyena clans.
