Shupavu and Njano, having heard this, report back to Scar and Ushari in the Outlands Volcano, who orders them to keep an eye on the situation about Makuu and Kiburi. Having heard the report, Scar announces that a Mashindano is a perfect way to cause a disturbance, by getting Kiburi and his crocs to take down King Simba while everyone else is distracted.

The Guard gets a little further but bumps into Reirei's pack. Kion turns to Bunga, who leaps onto some nearby rocks and bounds over the jackals, farting on them. Worn out, the Lion Guard reaches the volcano. Before they can ascend to get the ash, Janja's clan arrives. The hyenas attack, and the Lion Guard defend themselves, with even Makini helping out (albeit accidentally). They make their way up the volcano, where Kion observes the slowly setting sun.

The Outlanders continue their multiple attacks on the Pride Landers, with all of them being unsuccessful. Shupavu and Njano overhear Janja's hesitation over his position as well as Kion hosting a war on the Outlands, bringing the information over to Scar and Ushari. In retaliation, Scar orders Janja to go to the Lair of the Lion Guard and not let them out, not telling him the rest of the plan, but also informing him that Kion's Roar of the Elders, used at its highest potential in the Caldera has enough power to destroy him, should the plan fail. Janja and his clan go along with the mission, battling the Lion Guard inside the lair, whilst Kiburi's float and Reirei's pack plant dry grass near Pride Rock giving the vultures a chance to make an aerial assault, planting fire everywhere, trapping the Lion Guard, Janja's clan, and Simba's pride in the flames. Anga and Hadithi manage to rescue the Royal Family, while the Lion Guard rescues the hyenas (sans Janja who escaped to the Outlands to get Jasiri) and escape the flames. Once they've escaped, Janja, who is given a second chance by Kion, gives tells them how to defeat Scar. With this news, the Pride Landers, now joined by the hyenas, prepare for the final battle against the Outlands.

Once they're there, Kion battles the skinks and soon defeats them afterward before confronting the firey ghost himself. The ghost of Scar briefly speaks to Kion, before sending Ushari to attack Kion, giving him a facial wound identical to his great-uncle. Scar attempts to use this to anger Kion by stating that they are alike with their scars. Kion, resisting anger, and remembering his grandfather's words, offers Scar forgiveness, telling him he cannot judge him for his previous actions. With a single breath, Kion summons the Great Kings of the Past, sending down rain from the heavens, vanquishing Scar forever. Ushari, desperate to avenge Scar, attacks Kion again, making one last attempt on his life, but is intercepted by Bunga and falls to his death in the flames below, ending the battle for the Pride Lands once and for all.
