Scarry Night

Since the series finale of The Lion Guard, The Villain League has discovered something horrible to them: Janja has starting to learn about the truth of his involvement to Cobra and the others, and might be this close to learning about Fagin's true identity ever since the events of Rise of Scar. Thus, Cobra has to find a way to keep the truth from him fearing they'll lose him if they fail, as they discover that Scar has new abilities since this event, as he only communicates to Janja and the others through his volcano avatar, while Fagin watches in secret. (TBC...)

(New characters...)
 * Makuu- An arrogant and hot-headed Nile crocodile who is the leader of his float after he defeated Pua in a "mashindano." In season 2, Makuu no longer causes trouble for the Lion Guard where he strives to become a better leader, but in this episode, he is corrupted once more, but not forever.
 * Reirei and Goigoi- Two thieving jackal parents from the Outlands who played innocent during the Kupatana Celebration when they celebrate the unity of animals in the Circle of Life to steal anything through careful manipulation until they were chased out.
 * Ushari- An Egyptian cobra who teams with Janja to awaken Scar.
 * Mpishi- A harrier hawk who hunts for new meals anywhere.
 * Kenge- A monitor lizard who paralyzed and put up a challenge for the Lion Guard.
 * Makucha- A cunning and devious leopard from the Backlands. While he has appeared in the episodes of the series before, Makucha becomes the main antagonist of season 3, starting with the episode "The Harmattan." After hearing from Makini excitedly talking all about the Tree of Life and the rare animals, Makucha uses that info to make a new goal- sneakily follow the Lion Guard to the Tree of Life so that he could feast on the rare animals.
 * Chuluun- A cunning and sneaky snow leopard. First encountered by the Lion Guard in the mountains in the episode "Ghost of the Mountain," Chuluun eventually is defeated for the first time as the Lion Guard fight back against her alongside a group red pandas. After her defeat, however, she encounters Makucha and joins him to follow the Lion Guard to the Tree of Life.
 * Kiburi- An arrogant Nile crocodile who was part of Makuu's float. He and his followers defied Makuu's orders which led to them working with Ushari. While Kiburi challenged Makuu to a "mashindano," his three followers tried to attack Simba from behind only for the Lion Guard to intervene. Kiburi and his followers were kicked out of Makuu's float and were exiled to the Outlands by Simba, with Kiburi vowing to have his revenge someday. Upon running into Ushari again, Kiburi and his followers were led to where Scar's spirit is and formed an alliance with him.
 * Sumu- A scorpion under Scar's loyalty that almost killed Simba with his venom before he was cured with the volcanic ash from Scar's volcano.
 * Ora- A ferocious Komodo dragon who is the leader of his bank. First encountered by the Lion Guard on an island in the episode "Dragon Island," Ora is eventually defeated after Kion used the Roar to escape the island. But little did the Lion Guard know that Ora survived and has joined Makucha and Chulunn to follow the Lion Guard to the Tree of Life.
 * Mama Binturong- A sneaky and arrogant binturong crime boss who lives in the stone forest.
