The chief warthog is a large, brawny animal with a wild black mane and a reddish-brown pelt. His tusks are noticeably bigger and curvier than any of the other warthogs in the sounder.
Although the chief warthog's personality is not explored, he appears to be protective of his power and territory, with a willingness to jump into a fight without much thought.
While traveling with a family of warthogs, Pumbaa stumbles across a warthog sounder. With permission from the chief warthog, the family takes up residence with the sounder. While listening to the chief warthog talk to his family, the ill-tempered Growler gets an idea to frame Pumbaa for trying to take the sounder's land, which will get him in trouble with the chief warthog.
As Pumbaa continues to spend time with the family, Growler slips away and speaks with the chief warthog, lying to him that Pumbaa has plans to steal the sounder's land. Enraged, the chief warthog agrees to ambush Pumbaa when Growler leads him to the Rocks. With the plan in motion, Growler acts unusually friendly toward Pumbaa and tricks him into following him to the Rocks.
Growler leads an oblivious Pumbaa to the Rocks, where the chief warthog and his followers surround Pumbaa. Pumbaa tries to reason with the angry warthogs, but in his bumbling explanation, he manages to make them all laugh with his silly antics, and Growler's mother comes up just in time, breathlessly explaining her son's trickery to the chief warthog. Relieved to not have to hurt Pumbaa, the chief warthog invites Pumbaa and his friends to share one last meal of grubs with them. After the meal, Pumbaa says his goodbyes, and he returns home with his two friends, Simba and Timon.
