Janja is the leader of a teenage clan of Hyenas in the Outlands, who are descendants of the hyena clan who served Scar. He is the arch-enemy of Kion. He is the main antagonist in the 2015 Disney Channel TV movie The Lion Guard: Return of the Roar and of its 2016 follow-up series The Lion Guard.
He is voiced by Japanese rapper Andrew Kishino, who also voiced Doug MacFarland.
The Lion Guard: Return of the Roar Edit
Janja orders his clan members Cheezi and Chungu to capture a honey badger named Bunga (who had entered the Outlands to get his Baobab fruit back) so he may have him for lunch, but luckily, Prince of the Pride Lands 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 tells his clan that the Lion Guard were legendary and were the most powerful team of lions in the Pride Lands until the previous leader Scar destroyed them (after they refused to help him overthrow his older brother Mufasa). Janja then tells his clan that they will strike the Pride Lands that night before the new Lion Guard is formed 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.
Kion then uses the Roar of the Elders to drive the hyenas out of the Pride Lands back to the Outlands, but not before Janja swears vengeance.
