Nick Cheetah is the cheetah-type mecha BioBuddy partner of Chase Davenport. He is a positive thinker, & though a robot, has no sense of direction. Nick acts like an older brother to Chase. Also, he is able to transform into a motorcycle for Chase to ride into battle (where his face becomes the handle & meter). When fighting in robot mode, Nick can also use his rear wheels as handheld weapons.
