Scar was the younger brother of Mufasa, the uncle of Simba, granduncle of Kiara and Kion, the adoptive father of Kovu, and the brother-in-law of Sarabi.
In the past, Scar possessed the Roar of the Elders, led the Lion Guard, and later after having killed both Mufasa and his Lion guard, and exiling Simba, ruled the Pride Lands before his defeat by the claws of his nephew. He is also the main antagonist of Season 2 ahead of Kiburi, Janja, and Ushari.
He returns for Season 3 as the main antagonist of the opener Battle for the Pride Lands, which marks his final appearance in the show. He appeared as a hallucination to Kion later on in the season.
Unlike other known Pride Lander lions, Scar had a dark orange (deep brown in one painting) coat with a sleek, thick, darker brown mane and a light hair tuft on his chin. He had a triangular face and a pale muzzle and underbelly. His eyes were green when he was alive but in the volcano they are white, with a dark scar, running down the left one. He was a very lean lion, especially in comparison to his brother. As an teenager, his mane was short and reached his chest, but this grew bigger as an adult, stretching to his underbelly. In addition, he gained black tufts on the back of his forelegs.
In The Lion Guard Magazine, Scar is shown as a burnt orange lion with a black mane and paler fur on his muzzle, toes, and underbelly. Tufts of black fur are present on the elbows of his arms. The fur on his lower jaw is long, and his nose is black. He has a long muzzle, sharp features, and a thin, pink scar over his left eye.
As a fiery spirit, Scar has dark orange-brown coloring with a yellow nose and markings on his ears and the edge of facial fur. He has pale yellow eyes. His scar is shown as being pure white.
Scar cared only for himself. His selfishness fueled his anger.
Scar's personality is the polar opposite of Mufasa's: he's ruthless, mean-spirited, power-hungry, jealous, cruel, pompous, manipulative, charismatic, and insane. He is quite simply, pure evil. His jealousy stemmed from the fact that his brother was chosen to be king, a role which Scar believed should belong to him for boasting more intelligence. Scar was so hungry for power that he resorted to removing his own family and eliminating the kingdom for good. It was his thirst for power that caused him to lose the Roar of the Elders, and stripped the Pride Lands of its protectors.
Unlike the majority of Pride Landers, he does not believe in the Circle of Life concept and cares only about himself and his own glory. He is also highly intelligent, capable of planning ingenious schemes, and has a very low tolerance for individuals, which show a lack of intelligence and for failure. Scar has been known to use others to perform his deeds, keeping himself out of sight from those who may cause him harm and gets overconfident at times.
During his younger years, as leader of his Guard, Scar often did patrols on his own, showing his confidence. He was also a bit naive, as he trusted a Strange Lion that ended up double-crossing him. However, he proved to be very tactic with his intentions as after he turned traitor and slaughtered the stranger, he spun the narrative around in his favor to make him the hero of the story, showing his lust for attention.
In Battle for the Pride Lands, it is revealed that much of Scar’s maniacal personality is a result of being poisoned by a cobra when he was younger, as well as fueled by his jealousy and resent for his older brother, Mufasa. However, the venom did not turn Scar evil, as instead it brought out his darker traits as he became more willing to embrace his desires to be king. Scar still possessed enough control over himself that he could have chosen to remain as leader of the Guard, but his desires for the throne and his jealousy for his brother convinced him he was the better king. In addition, it was also revealed that Scar's descent into fury was a result of being ridiculed by a teenage Mufasa, and giving the nickname "Scar," after his facial wound, whilst Scar himself was looking for praise, showing how truly petty Scar is.
In the end, Scar has no concept of forgiveness nor compassion towards others, caring only for himself, and has no comprehension of family, clearly shown when he is surprised and dumbfounded when his great-nephew, Kion forgives him for his crimes and instead calls upon the Great Kings of the Past to judge Scar rather than destroying the evil spirit in hatred.
Scar was the second-born in the Pride Lands to the King and Queen of Pride Rock, under the name of "Askari", who was his ancestor and the leader of the original Lion Guard, and had an older brother named Mufasa, who was destined to be the next King. As traditional for all second-born children of the royal family, Askari was tasked with leading the Lion Guard to protect the Pride Lands and defend the Circle of Life. As the leader and fiercest member of the group, Askari was bestowed a power called the "Roar of the Elders" by the Great Lions of the Past which, when used, would cause the Great Lions of the Pride Lands' past to roar with him, which made him feel powerful.
Scar got his nickname from Mufasa, after being bitten in the face as an adolescent by a cobra after being led to him by a strange lion, telling him that the most powerful lion should be the real king and that when he helped him both could rule over everything. All he needed was to do what the rouge lion said to him and he would cure the venom. But Scar became infuriated and roared at the lion and cobra with the Roar, blasting them towards the volcano where they were destroyed.
Enraged that Mufasa ridiculed him instead of praising him for defeating the lion and cobra, Scar planned to dethrone his older brother as king by using the Roar of the Elders against him. When the rest of his Lion Guard refused to assist him in his plot, Scar was furious and eliminated them by using the Roar of the Elders on them, forming Broken Rock in the process. As punishment for using the Roar of the Elders for evil, Scar became weakened by this misdeed and lost the ability to use the Roar forever, making him shriveled and worse. In the years that followed his Lion Guard's downfall, Scar still concentrated his life on plotting to claim his older brother's throne and continued to devise schemes with three hyenas from the Elephant Graveyard, lead by a female hyena named Shenzi to rule the Pride Lands.
After his nephew Simba was born, stripping him as Mufasa's successor to the throne, Scar plotted with the hyenas to kill both him and his older brother and take control of the Pride Lands. In the end, though, he was only able to slaughter Mufasa using a wildebeest stampede and convinced a young Simba to run away, blaming him for Mufasa's death. However, when Simba came back as a young adult and discovered the truth behind Mufasa's death, he battled, and defeated his uncle and reclaimed the Pride Lands. After Scar was defeated by Simba and thrown off Pride Rock into a burning fire that broke out during the fight, he was double-crossed, attacked, and eaten alive by his hyena henchmen.
Sometime prior to Simba's return to Pride Rock, Scar hand-chose Kovu to be the next king in the wake of his demise. Kovu is the youngest son of Scar's most loyal follower, Zira, with whom he shared a very close relationship, enough to explain to her about the Roar of the Elders, and all its powers. Zira's faithfulness to Scar lead her to attempt to continue his legacy through his protege Kovu at long last, years after Scar's defeat by the claws of Simba.
After Kion is told that he will be the leader of the new Lion Guard, Simba and Rafiki show him the history of the Guard, using paintings within the Lair of the Lion Guard, including Scar's leadership and how he lost it by eliminating his own Lion Guard after they refused to help him overthrow Mufasa. As Kion, Bunga, Simba, and Rafiki leave, a painting is shown with Scar's head rising from a volcano, foreshadowing later events.
Later, when Mzingo informs Janja's clan of Kion's new position, Janja wonders how that could be possible, since Scar was the last lion to lead the Guard, up until he eliminated them.
As Kion and his family discuss Makuu's rise to power, Nala gently reminds Kion, that Simba had to fight Scar to reclaim his leadership. Scar's name was mentioned again, when Kion backed down when using the Roar in a state of fury, saying that he did not wish to become like his great-uncle.
It is revealed that a group of lionesses were loyal to Scar during his reign. Among those lionesses was Zira, whom Scar trusted enough to share the secrets about the Roar of the Elders.
It is also revealed that prior to Simba's return, Scar chose Zira's youngest cub, Kovu to be his heir. Sometime after Scar's defeat, Simba banished Zira, her family and other lionesses loyal to Scar from the Pride Lands to the Outlands. Zira mentions Scar multiple times, claiming that, if it weren't for Simba, Scar would still be King. But Kion says that Scar was never the real king. Infuriated, Zira reveals her true colors and orders an attack on Kion. However, just before the Outsiders can hurt him, Zira offers to forgive him, if he will join her and leaves him under the watch of her pride, while she goes to fetch her cubs.
During the final fight between the Outsiders and the Lion Guard, Bunga urges Kion to use his Roar, but Kion worries that he will lose the Roar, as Scar did for using it against other lions. However, Bunga reminds Kion that Scar did not lose his Roar, because he used it against other lions, but because he used it for evil. Kion then uses the Roar successfully and blows away all the Outsiders.
A painting of Scar and how he destroyed his Lion Guard is viewed by Kion in the Lair after he uses the Roar in anger when saving his mother, Nala, from Janja's clan. When Bunga mentions how his uncles called him the worst lion ever, Kion becomes more troubled. Worried that he may be following in Scar's footsteps with his temper, Kion later talks to Mufasa, who tells him that Scar held no interest in helping others, caring only for himself.
Fed up with being hurt anytime he is near the Lion Guard and after discovering Kion's secret of speaking with Mufasa, the venemous Ushari starts pondering how he can use that information for his own benefit. He runs into Janja's clan, and in order to save himself from being eaten, Ushari starts trying to bargain with Janja, telling him of Kion's secret. The pair wonder, if they can bring Scar back to life, and do some research. After luring Makini into speaking with her mentor about it, they discover a way to bring him back by using a bakora staff and a powerful Roar near the volcano and get to work on a plot. The hyenas steal Makini's Bakora Staff and, knowing that Kion's Roar is most powerful when his loved ones are threatened, kidnap Kiara, dragging her back into the Outlands with them. Although the Lion Guard save her, Janja manages to taunt Kion into using the Roar in anger, which causes the volcano to erupt. Once they have left, Janja enters the volcano and finds out that Ushari is still unable to summon Scar. In a temper, Janja grabs the staff and throws it in. With a small eruption, the ghost of Scar suddenly appears and, after being questioned, introduces himself.
Now that he has returned, the resurrected Scar begins to plot his revenge on his nephew, Simba and reclaim control again over the Pride Lands, first forming an alliance with Ushari and Janja and his clan. Upon learning from Ushari's skink spies, that the Lion Guard has accidentally awakened Makuu and his float from their hibernation during the dry season, Scar sees this as an opportunity to wreak havoc in the Pride Lands and orders the Skinks to keep watch on the situation and inform him of any changes. When informed that a rebellious member of Makuu's float, Kiburi, has challenged the latter to a Mashindano, Scar decides this is the perfect opportunity to get rid of Simba, knowing that many Pride Landers, as well as the royal family, will be in attendance. He orders Ushari to trick Kiburi into believing that if he ambushed Simba, he will rule the Pride Lands. However, while Ushari succeeds in tricking Kiburi, the plan ultimately fails, due to the Lion Guard's interference. This also causes Kiburi and his three crocodile followers to be banished from both, the crocodile float and the Pride Lands. On their way to the Outlands, Kiburi and his followers run into Ushari again, who takes them to the volcano, where Scar reveals himself to them. Scar explains his revenge plan to Janja, Ushari, Cheezi, Chungu, Kiburi and his followers, explaining his scheme to unify all the animals in the Outlands. With an army of henchmen at his side once more, Scar seeks to ignite a hostile takeover of the Pride Lands to reclaim the kingdom as his own domain and break the Circle of Life for good.
Upon hearing from one of Ushari's skink spies, that Beshte has ended up in the Outlands alone, Scar sees this as the perfect opportunity to eliminate the strongest of the Lion Guard and thus weaken it. After Cheezi and Chungu question it, Scar irritably explains, that the heat of the Dry Season weakens hippopotamuses. He states that due to Beshte's trust in the skinks, it wouldn't be difficult to take advantage of this, and states that the skinks would lead Besthe to Rocky Plateau, where Janja, Cheezi, and Chungu could trap and then crush him with huge rocks.
The plan nearly succeeds, but is ultimately thwarted when the rest of the Guard arrives just in time, and Kion uses the Roar of the Elders to send the hyenas flying away. After landing near the volcano, Janja, Cheezi, and Chungu decide not to return to Scar immediately, knowing that he will be furious at them for their failure. As they begin to walk away, however, Ushari arrives and coldly informs them, that Scar wishes to see them and isn't happy. Then, a small eruption can be seen at the top of the volcano, apparently confirming this.
Scar sends Janja, Cheezi, and Chungu in search of Reirei's pack, wanting to get them on his side. During their search for the jackals, Janja and his goons stumble on Jasiri, who marks the area as her turf (something which Janja forgot to do) and defeats and sends them back to the volcano, when they try to get it back. Upon hearing about Jasiri, Scar, at first, sees her as a possible valuable ally, but Janja reveals that Jasiri is friends with the Lion Guard and also respects the Circle of Life, unlike the other Outlanders. With this information, Scar changes his mind and decides that she is a threat. He orders Janja to get rid of her immediately and to do this with his entire clan, as he perfectly understands that Jasiri is too strong for only him, Cheezi and Chungu. As they leave, Scar coldly warns Janja to not disappoint him again.
Scar stops an argument between Janja, Cheezi, Chungu, and Ushari (the latter having been trampled on by the others) and learns from the hyenas, that they have discovered a supply of watermelons, intended for the elephants through the Dry Season. Scar sees this as a potential to break the Circle of Life by removing the melons from the Pride Lands as this will cause the elephants to become dehydrated as a result. He orders Janja and his goons to return and steal all of the melons. But Janja is hesitant as the Lion Guard had already prevented them from doing so earlier and will probably be waiting for them. Ushari then reveals having a friend, who can help and will not disappoint them. Satisfied, Scar orders Ushari to find his friend Kenge and tell him to deal with the Lion Guard.
Scar orders the hyenas to kidnap Zazu, because the bird has valuable information about the King, Simba, that Scar wants to use for his advantage. When Janja questions him on what to do next, Scar orders him to interrogate Zazu. Although this annoys Janja, Scar explains that Zazu is "keeper of all the secrets of the Pride Lands", and that the information Zazu could disperse would make it easy for them to take over the Pride Lands. He then warns Janja to hurry up, as the Lion Guard must already be searching for Zazu.
At some point, Scar finally managed to do both, find Reirei's pack and get them on his side. In the volcano, Scar is shown speaking with Reirei and Janja, after they managed to separate the Lion Guard by attacking the Pride Lands in two different places at once. He reveals that their first mission was merely a test when Janja questions why they went to all that trouble and still returning to the Outlands with nothing and that their main objective would be in the next mission - eliminating Rafiki. When Janja and Reirei show confusion at this plan, referring to 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 that the skinks have told him is meditating at Mapango Cliffs, while Reirei's pack will distract the Guard. He next appears in a dry season fire, angrily telling a retreating Janja to stay and fight. Janja complains that his clan is outnumbered, but Scar responds with 'not for long', as the jackals soon arrive to help, so Janja does as Scar says. Kion, who was chasing after Janja, catches a glimpse of Scar before he vanishes, causing him to wonder about what he just did see there. After the hyenas and the jackals are defeated, Kion goes to the area where Scar appeared and sees that a scorch mark with a strange symbol remains. Rafiki recognizes it from the Paintings of the Past, as a sign of terrible evil and goes off to consult the Paintings of the Past for further information.
While the Pride Landers gather for Kumbuka, Scar gathers his army, now with Mzingo and his flock on their side. He announces that they will finally destroy the Lion Guard and end Simba's reign. When he is questioned, he informs them that he will be getting some help and subsequently introduces them to a scorpion, named Sumu. He then remarks that the day the Pride Landers celebrate his defeat will soon be known as the day that he returned. After successfully stinging Simba, Sumu returns to the Outlands to give Scar the good news. He is surprised to learn that bringing the Lion Guard to their volcano was exactly what his leader wanted. Scar orders Ushari to tell everyone to get ready for the Lion Guard. Although unaware that Scar has sent Kiburi's float, Reirei's pack and Janja's clan to delay them, the Lion Guard plow through the groups and make it to the volcano, where Makini picks up the cure for Simba's ailment, volcanic ash, and places it safely into a gourd. Before they can leave, Scar finally reveals himself, rising from the flames. When Kion recognizes him, Scar commends him for his intelligence. Scar further reveals that he was behind his father's attack, and he extends his commendations to the Lion Guard for working out that he was the mastermind behind everything. But when the Lion Guard turns to leave, regardless of knowing that his plan failed, Scar summons the Army of Scar.
The Army of Scar starts to confront The Lion Guard and slowly corners them to a small ledge in the volcano, right in front of their leader above a pool of lava. When Kion considers using the Roar, Scar warns Kion of the dangerous side-effects of using it in a volcano, but the young cub surprises him by using the Roar in a way he never thought possible, Kion is able to defeat the majority of his army.
Infuriated, Scar commands Mzingo's Parliament to pursue them, and get the ash back from Makini, whose gourd contains it. But despite their best efforts, the Lion Guard work together to ensure Makini and the gourd's safety, and Kion's roar blows the vultures straight back into Scar's domain.
Looking out over his tired and defeated army, he comments darkly that the war has just begun.
Upon learning of his evil uncle's return from his son, a concerned Simba goes with him to consult Mufasa and asks about how to defeat Scar. Although the problem is unfortunately beyond his experience, he is certain that, between his son, who has already saved the Pride Lands before from Scar and his grandson, who is the leader of the Lion Guard, that they can defeat Scar. He leaves them with the message that the wisdom is within the Pride Lands, leading both lions to believe that he could be referring to an animal. And Simba knows just who he may be referring to and sends Fuli and Makini to search for an old and wise tortoise named Kongwe. Scar is later mentioned again when, after arriving at Pride Rock, Kongwe confesses that not even she is sure how to defeat Scar, but assures everyone that they will find the solution eventually and that they just need to look. She also assures them that good will always triumph over evil, in time.
Scar orders his minions to set fire to the Kilio Valley. After they succeed in doing so, he rises from the small flame of a remaining flaming stick, that was thrown to the ground by Mwoga and praises his army for doing their work well, before ordering them to remain in Kilio Valley. When being questioned by Kiburi and Reirei, Scar reveals that his plan is to take over the Pride Lands piece-by-piece, so that the Lion Guard will have nothing left to defend the Circle of Life and protect the Pride Lands.
Scar summons Janja and his clan back to the volcano. He stops a brief argument from Ushari and Janja (as the Cobra was berating the hyena for arriving late) and orders the hyena leader to enter the Pride Lands with his entire clan, enter the riverbank above Hakuna Matata Falls at night, and push the rocks into the river until it stops the water from flowing as this will cut off a major water supply during the middle of the dry season, which will thus cause the Pride Landers to get thirsty and will plunge the Pride Lands into unrest, desperation, and chaos. However, Scar is unaware that a female chameleon named Kinyonga, who is spying on him by using her camouflage ability, has heard everything and is planning to expose it to the Lion Guard so they can foil his latest scheme.
Soon after the plan has been confirmed, however, Shupavu and her group notice Kinyonga's shadow against a wall, and brings her to the attention of Scar, who then asks to know who dares to spy on him. Ushari then commands them to stop the intruder, and the skinks pursue Kinyonga out of the volcano.
Jasiri tells her clan that Scar has returned, but that they also will help the Guard to defeat him by forming a Hyena Resistance. Elsewhere in the Outlands while preparing to attack Mizimu Grove, Janja's clan gets blocked by a rock slide caused by the Hyena Resistance. When Scar hears the news, he gets super mad and fiercely roars at Janja, knocking him away. Scar almost grows angry at Kiburi too, who saves himself by stating that the problem was that the plan did not go as planned. Scar then orders Kiburi's float to take over Big Springs. However, the Hyena Resistance stops them. Then, he orders Reirei's pack to take over Ukuni Woods. The Hyena Resistance watch above, and roll down a large boulder to the front of the cave, sealing Reirei's pack in before they can leave. Later, Janja and the skinks report back to Scar and reveals that Jasiri and her Hyena Resistance are behind all of this. After hearing that Janja lied to him about eliminating Jasiri on their previous encounter, Scar is furious and demands that he takes care of her and her clan for good, by playing them at their own game. He tells Janja to announce that he and his clan will be attacking Mizimu Grove again, but will instead attack her and her clan, while the Lion Guard is at the grove. Janja gets confused initially, but Scar soon makes it clear. After telling him to also bring the jackals and crocodiles with him and his clan, Scar coldly warns Janja not to let him down...again.
After hearing from Shupavu and Njano that Kion, Bunga, Kiara, Tiifu, and Zuri are at the Mud Pots at the edge of the Pride Lands and how easy it would be to set the place ablaze, Scar orders Njano to fetch him a vulture, who will be delivering a gift of fire to Kion and his companions.
Scar is furious when he hears that Janja's clan, Reirei's pack and Kiburi's float were defeated again. They then explain that it was actually a very big and strong gorilla named Shujaa who defeated them, not the Lion Guard and that he was able to tear apart the landscape easily. Scar's fury turns into interest and excitement upon learning this. Since the gorilla is destroying the Pride Lands while he's trying to help the Lion Guard, Scar orders his army to keep attacking so the gorilla can make more damage.
Scar finds out that the Pride Landers are working together to defeat him. When Janja finds this funny, Scar tells him that Pride Landers forming an alliance would mean problems for his plan. However, since Kion's friendship with Makuu was being swayed, Scar orders his army to take over Makuu's watering hole, something, that ignites excitement in Kiburi.
After hearing the news of Makini's Mpando Mpaya from the skinks, Scar orders his army to ruin the event. During the battle, small flames fall from the sky, setting Mizimu Grove on fire and destroying it. Scar then appears in the flames, making himself known to of all the Pride Landers and confronts Simba for the first time since his return. When Simba demands to know what Scar wants, Scar taunts his nephew by calling him naïve and listing his success in destroying first the Kilio Valley, then Big Springs, and now Mizimu Grove. He then leaves laughing after declaring that soon all of the Pride Lands will belong to him again. Terrified to learn that Scar has returned, the Pride Landers panic and consider leaving the Pride Lands.
Several months into the war with the Lion Guard, Scar hears from his skinks that Janja is considering defecting from his army and joining Jasiri, as well as the Lion Guard planning to assault the Outlands. Scar summons Janja and tells him that Kion is powerful enough to defeat him and could do so if he uses his most powerful roar in the caldera. Scar then orders Janja to go distract the Lion Guard by luring them into their lair at Pride Rock and not letting them escape. However, Janja doesn't realize that the plan wasn't just meant to eliminate the Lion Guard and the Royal Family, this was also Scar's plan for eliminating a potential hyena revolt. While Janja and the hyenas are distracting the Lion Guard inside their lair, the other Outlanders start a fire on Pride Rock and Janja barely escapes the lair before the main exit is blocked off. Janja realizes Scar betrayed him and goes to find Jasiri for help while the Lion Guard and hyenas escape the lair using the underwater entrance to Beshte's pond. Scar appears on top of the fire on Pride Rock and sees that Kion survived the fire. Scar tells Kion to lead the animals out of the Pride Lands since Kion isn't powerful enough to defeat him, but Kion can come to the caldera if he wants to try before disappearing. Having defected to the Pride Lands, Janja tells Kion what Scar told him that the only way to defeat Scar is to use the most powerful roar at the caldera.
Back at the Caldera, Scar tells Ushari that he anticipated that Kion would survive and admits that he lied to Janja about how he could be defeated by Kion's roar. Even though Kion's roar could defeat Scar, if Kion were to use his most powerful roar in the caldera, it would cause a massive volcanic eruption that would turn the Pride Lands into a wasteland and kill all of Scar's enemies at once. For the next part of his plan, Scar tells Ushari how he actually got his scar. In a flashback, an adolescent Scar is patrolling the Pride Lands, when a strange lion walks up to him. Knowing that he has the Roar of the Elders, the strange lion filled Scar's head with lies, and suggested that Scar should be the king of the Pride Lands. But he then met a strange cobra and the snake gave him a scar on his left eye with venom, which caused his darker desires for the throne to emerge out in force. The Lion tried to coerce Scar into obeying him in exchange for a cure, but Scar used the Roar to eliminate the Lion and the Cobra. After a young Mufasa brushed off what happened to Scar instead of praising him, Scar wanted his Lion Guard to eliminate Mufasa so that he could take the throne. However, they refused to obey him, so Scar used the Roar and destroyed them. This caused him to lose the Roar forever, which made him shrivelled and horrible. Losing the Roar also led up to him killing his brother, exiling his nephew, and ruling the Pride Lands with an iron claw before he was defeated and killed in his fight with Simba. Once Scar has informed Ushari, he tells the cobra that in order for the plan to work, Kion must lose control of the Roar, before announcing that the day of the battle will mark the day Kion gets his scar.
Afterward, the Lion Guard arrive at the Outlands Volcano after having defeated the Outlanders. Scar confronts the Guard and orders Ushari to attack Kion, who is left with a scar over his left eye, like his great-uncle's. Scar tries to goad Kion into using the Roar in anger by singing his own version of Sisi Ni Sawa. Kion remembers not to fight fire with fire, and tells Scar that he forgives him for all the evil deed he has done, much to Scar's horror. Kion then summons the Great Lions of the Past with a gentle blow of air, who then create rain over the volcano. Being made of fire, Scar's spirit is extinguished by the rain. In his last words, Scar tells Kion that the Roar of the Elders is a curse and that he will see that they are the same before vanishing completely. The lava then hardens into rock, destroying the Mark of Evil, finally ending Scar's threat to the Pride Lands once and for all.
Whilst Kion and the Lion Guard are en route to the Tree of Life, Scar appears as an hallucination in a pool of water to Kion, telling him that they are the same. However, Kion rejects the claim and slaps against the water, dissolving the image of Scar.
After Queen Janna's funeral, Kion talks to Rani about his grandfather Mufasa and what his great-uncle Scar did to him. Rani responds stating she already heard it from her grandma, also mentioning she learned what "Sisi ni sawa" means from her grandmother Janna.
In a news article, Nuka, Vitani, and Kovu are noted to be his descendants. This is, however, impossible as their mother Zira, is a mere follower of Scar, not his mate. However, according to Simba's Pride director Darrell Rooney, and writer Flip Kobler, Zira was originally designed to be Scar's mate, with Nuka, Vitani, and Kovu being Scar's cubs. However, this would've lead to incest between Kiara and Kovu as first cousins once removed. As a result, Zira's relationship with Scar was obscured to make her "just a follower." This would suggest Scar is unrelated to Zira's children.
According to Ford Riley, Scar was originally named after Askari, the leader of the first Lion Guard. It was shortened by Mufasa to the nickname "Scar" after he got his scar.
This contradicts the book, A Tale of Two Brothers, where Scar's original name was Taka and he received his scar from a buffalo stampede. However, unlike the book, The Lion Guard is confirmed by Disney to be canon to the original film.
He is the third deceased character in the series following his ancestor, Askari and his older brother Mufasa.
