Kevin O'Donnell, also known as Kenichi Ooyama, appears as a human character in the 2009 animated special *Jungle Emperor: The Brave Can Change the Future*. He is the son of Kenzou Ooyama, CEO of the artificial sanctuary Neo Jungle, created to house animals relocated from their natural habitats. Kevin possesses the unique ability to communicate with animals, though others initially dismiss this as childish fantasy.

Living within Neo Jungle's controlled environment, Kevin exhibits deep curiosity about the animals and respectful admiration for his father's work, despite his inherent naivete regarding the project's ethical implications. Viewing a demonstration video featuring a white lion intensifies his fascination, driving him to secretly explore Block B. There, near a waterfall, he encounters Leo. Initial wariness from Leo and his companion, Coco, fades as they sense Kevin's genuine curiosity and lack of malice.

This encounter sparks a significant bond with Leo. Through Panja and Eliza, Kevin learns of the animals' displacement and the artificial nature of Neo Jungle under his father's control. This knowledge triggers a shift in his perspective. He witnesses the escalating conflict between the animals and the human administration, particularly his father's increasingly authoritarian actions, like resetting Block B, which endangers the animals.

As Kenzou's actions intensify, Kevin decisively rejects his father's authority and aligns himself with the animals, actively supporting their rebellion. He aids their escape from Neo Jungle and commits to accompanying them on their journey to find a new, natural habitat in Africa, symbolizing his complete break from his previous life and acceptance of his role as an animal advocate.
