Chungu's personality is a bit similar to Banzai. He is a little dimmer and less intelligent than Cheezi.
Chungu, unlike the other hyenas, is more muscular with spots on his back, gray and black fur, black muzzle, and black paws and nose.
Intellect: Chungu is not as intelligent as Janja, but he quickly knew that Kion was too afraid to come to save Bunga from harm. But with his great loyalty, he knew that he wouldn't be fooled by Tamma, as he pointed out that he only listens to Janja's orders and knew that Tam figured that Tamma was lying.
Skilled Combatant: Chungu's size and strength allows him to hold his own against Kion for a short period of time.
Animal Strength: He was able to hold his ground for short period of time against Kion's roar.
Chungu and Cheezi are sent by their boss Janja to capture Bunga (who had entered The Outlands to get his baobab fruit back) so he can have him for lunch. Luckily, Kion is able to save his friend by using The Roar of the Elders, which shocks the two hyenas, giving Bunga time to escape.
Later, Chungu and the other hyenas learn from Mzingo that Kion is assembling a Lion Guard to protect The Pride Lands to which Janja declares that the clan will attack The Pride Lands that night.
Chungu accompanies Janja and the rest of the clan when they attack a gazelle herd and cause a stampede, which Kion's older sister Kiara gets trapped in. Luckily, Kion and The Lion Guard come to Kiara's rescue and get the herd away from her. Kion then uses The Roar of the Elders to drive Chungu and the other hyenas back to The Outlands.
Chungu, Janja, and Cheezi attack an oryx herd but are stopped by The Lion Guard. Kion orders the others to calm the herd while he goes after the hyenas, but a log snaps under Kion's feet and he falls into a river which sweeps him to the Outlands.
Chungu and his clan later appear when they try to attack a female hyena named Jasiri, who had just helped Kion find Flat Ridge Rock in order to escape the Outlands. Luckily, Kion returns and saves Jasiri by scaring Chungu and his clan off with The Roar of the Elders.
Chungu, along with Cheezi, is seen with Janja when Mzingo arrives and says that Kiara is temporary queen and is squabbling with Kion, which gives Janja an idea.
Chungu, Cheezi and the rest of the clan ambush Kiara when she comes to Broken Rock to have a supposed peace treaty with Janja. Just as Janja pins Kiara down, Kion comes to his sister's aid and is soon joined by the rest of The Lion Guard, causing Chungu and the rest of the clan to flee with Janja.
Chungu, Janja, and Cheezi are first seen attacking a wildebeest herd but are forced to flee back to the Outlands by The Lion Guard.
After learning that Ono has an eye injury (due to getting sand in it) and is out of commission, Chungu along with Cheezi aid Janja in trapping the remaining members of The Lion Guard in a canyon before preparing to pick off a zebra herd.
Luckily, Ono (despite his injury) arrives and moves the zebras away from the canyon, giving Kion time to blast the rocks trapping them with The Roar of the Elders. After getting caught up in the blast, Chungu returns to the Outlands with Janja and Cheezi.
Chungu and his clan pursue a jackal pup named Dogo, but Kion and The Lion Guard come to the pup's rescue. When hearing that The Pride Lands is celebrating Kupatana, Janja allows The Lion Guard to take Dogo and leaves with Chungu and the rest of the clan.
Chungu is grooming Janja just before Cheezi arrives and informs them of Bunga being in the Outlands. Chungu and the clan ambush the honey badger, but before they can harm him, Fuli comes to her friend's aid.
The two friends then use a piece of broken rock to float downstream in lava whilst being pursued by Chungu and the clan. Luckily, Kion, Beshte and Ono arrive and save their friends, leaving Chungu, Janja and Cheezi trapped on a log with no food.
He and Cheezi are banned from the Outlands by Janja because he believed it was always their fault when his plans failed every time. However, after the betrayal of their replacements Nne and Tano against Janja, and after the Lion Guard defeat the two rebel hyenas, Janja accepts Cheezi and Chungu to go back with him in the Outlands.
