Janja

"Tonight, we outlanders will feast; hyenas and vultures alike! Tonight... we strike!"

- Janja to his followers.

Janja is the main antagonist of the 2015 Disney Channel TV film The Lion Guard: Return of the Roar and one of the main antagonists of its 2016 series The Lion Guard, both of which are based on the 1994 film The Lion King. He is the teenage leader of the Outlanders, a clan of hyenas who reside in the Outlands and serves as the arch-nemesis of Kion and The Lion Guard. He also has a major-domo: a vulture named Mzingo.

He is voiced by Andrew Kishino.

The Lion Guard: Return of the Roar
Janja orders his clan members Cheezi and Chungu to capture Bunga (who had entered the Outlands to get his Baobab fruit back) so he may have him for lunch, but luckily Kion is able to save his friend by unknowingly using The Roar of the Elders (which when used, causes the lions of the Pride Lands past to roar with him) which gives Bunga time to escape Cheezi and Chungu.

Later, Janja is informed by his major-domo Mzingo that Kion is setting up a Lion Guard to protect The Pride Lands. After hearing this, Janja informs his clan that they will strike the Pride Lands that night by singing "Tonight We Strike". Janja, Mzingo and the rest of the clan attack the Pride Lands and cause an antelope stampede, scoring several antelope that would've been plenty for them to eat, but aims to kill the rest of the herd. During the chaos, Kion's older sister Kiara gets trapped in the stampede. Luckily, Kion and the Lion Guard are able to lead the antelope away from Kiara and get her to safety.

The Lion Guard then drive the hyenas out of the Pride Lands back to the Outlands, but not before Janja swears vengeance.

"Never Judge a Hyena by Its Spots"
Janja along with Cheezi and Chungu are seen attacking a oryx herd, before The Lion Guard arrive. Kion orders the rest of The Lion Guard to calm the herd while he deals with the hyenas. However during the pursuit, Kion falls into a river and is swept into The Outlands when a log snaps under his feet.

Later near the end of the episode, Janja and his clan confront a female hyena named Jasiri (who according to their interactions, has encountered the clan before) who had entered Janja's territory to help Kion get out of The Outlands. Though Jasiri is able to easily fight off Cheezi and Chungu, Janja is able to pin her to the ground. But before he could to kill her, Kion returns and saves her by using The Roar of the Elders to scare Janja and his clan away.

"Can't Wait to be Queen"
Janja is informed by Mzingo that Kiara has been left in charge of The Pride Lands by Simba and is squabbling with Kion. This gives Janja an idea, so he tells Mzingo to give a message to Kiara.

The message Janja has Mzingo tell Kiara is that he wants a peace offering and asks her to meet Janja at Broken Rock, which is neutral territory between. The Pride Lands and The Outlands.

Kiara decides to meet Janja and goes to Broken Rock, but senses that something is wrong. Just then, Janja, Chungu, Cheezi and the rest of the clan approach her where Janja declares that with Kiara in his grasp, Simba will have no choice but to hand The Pride Lands over to him. The clan circle around Kiara and a couple leap at her. Kiara's agility secures her victory, but this is short lived when Janja pins her down. But before he can attack, Kion arrives, but this doesn't bother Janja as his clan is up 6-2. Just then, the rest of The Lion Guard arrive and join Kion and Kiara, marking the numbers as equal, which causes Janja and his clan to flee.

"Eye of the Beholder"
Janja and his minions start a stampede in a wildebeest herd, but are chased back into the Outlands by Kion and The Lion Guard, but during the process, Ono gets sand in his eye, temporary losing sight in that eye.

Later, Janja overhears Mzingo and his flock talk about Ono's poor vision and plans with Cheezi and Chungu via singing "Outta the Way", that they will trick The Lion Guard while Ono is out of commission.

After spotting Janja overlooking a zebra herd, The Lion Guard (sans Ono) go out to investigate. They go into a canyon, where they are trapped by Janja, Cheezi and Chungu, who then go to attack the zebras.

Luckily, Ono, despite his injury, arrives and is ordered by Kion to move the zebras while he uses The Roar of the Elders to blast the rocks trapping them. With The Lion Guard back in action, Janja and his minions flee.

"The Kupatana Celebration"
Janja and his clan make a small appearance in this episode when they chase after a jackal pup named Dogo. But when Kion and The Lion Guard come to Dogo's rescue, Janja learns that The Pride Lands is celebrating Kupatana and allows them to take Dogo, before leaving with his clan.

"Fuli's New Family"
Janja is being groomed by Chungu just before Cheezi arrives and informs him about Bunga being in the Outlands. Janja and his clan surround Bunga and prepare to attack him, but are stopped by Fuli. Using a piece of broken rock, Bunga and Fuli float downstream in lava whilst being pursued by the hyenas.

Luckily, Kion, Beshte and Ono arrive and stop the hyenas, leaving Janja, Cheezi and Chungu trapped on a burning log with no food.

"Follow That Hippo!"
Janja sneaks into the Pride Lands with Cheezi and Chungu. Upon seeing Ono flying above, the trio hide in a until he is gone. Chungu loudly compliments Cheezi, but Janja warns them that Ono may hear them.

Later, the trio hear a young elephant named Mtoto and his friends Shauku, Kwato, Kambuni and Gumba chase hyraxes and shout Janja's name. The trio follow the group with Chungu wondering if they are actually chasing the kids, with Janja telling him that they're playing pretend but it's about to get real. Janja, Cheezi and Chungu reveal themselves to the young animals and pursue them. Janja chases Mtoto, who evades him by causing Janja to crash into a boulder. Cheezi and Chungu (having failed to catch the others) approach Janja who decides to go after Mtoto as he is the slowest.

Janja, Cheezi and Chungu corner Mtoto near a river, but Beshte jumps out of the water and gives Mtoto (who can't swim) a ride on his back down the river, with the hyenas in pursuit. Janja and Cheezi wait for the two to pass beneath them, but Mtoto Ducks, causing the two hyenas to knock into each other. After Kion and the rest of the Guard arrive, Janja, Cheezi and Chungu are knocked into the river and are chased away by crocodiles.

"The Call of the Drongo"
Janja, Cheezi and Chungu are first seen pursing a herd of impalas with Janja calling out they only want to invite them to dinner with the impalas as main course. The Lion Guard arrive with Beshte standing in front of the hyenas, causing them to crash. Janja silences Chungu when he attempts to tell the Guard the joke Janja said. Kion then orders the trio to leave.

The trio then hear Janja telling someone they look tasty and he is going to eat them. Cheezi and Chungu think that Janja said it, but Janja says that he didn't say anything. He discovers a drongo bird named Tamaa impersonating him to scare a mouse. Cheezi manages to grab Tamaa and Janja says that they may not eat him if he helps in his new plan.

Janja instructs Tamaa to impersonate Kion, but Tamaa at first protests (as he had met Kion earlier and was warned not to use his voice for his own benefit), but agrees after Janja threatens him. After Tamaa uses Kion's voice to lure the impalas to the Outlands, the hyenas give chase and Janja declares that dinner is being delivered. Tamaa asks if he can go now, but Janja refuses, as Tamaa may still be useful to him. After he, Cheezi and Chungu lead the impalas to a dead end, Janja is pleased at how easy his plan worked and says that the hyenas are never going to let Tamaa go and beings to stalk the impalas.

However, Janja hears the voices of the Guard, saying that they are surrounded and that they should leave and let the impalas go. At first, Janja is terrified, but notices that Cheezi doesn't have Tamaa. He finds Tamaa and says that the Guard isn't there, before being pinned down by Kion. Janja tries to convince Kion that he, Cheezi and Chungu were trying to help the impalas, but this fails and he, Cheezi and Chungu flee.
