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 a clan of hyenas who resides in the Outlands and serves as an enemy to 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 It's Spots"
Janja along with Cheezi and Chungu are seen attacking a gazelle 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 face against a female hyena named Jasiri who had helped 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. Luckily, Kion returns and saves her by using The Roar of the Elders to scare Janja and his clan away.
