Cheetor is full of youthful overconfidence. He's also the fastest Maximal on four legs, so he gets into way too much trouble. Thankfully, Optimus Primal keeps a steady eye on him. In return, Cheetor has grown to idolize Primal, whom he calls "Big Bot." Optimus Primal knows the young and inexperienced Cheetor needs a good role model, so he doesn't mind too much. And, hey, he's a good kid. Just...keep him away from Dinobot, okay? Impressionable minds, and all.
