In a contest by @Special Riolu made this! I'll explain why who is who in a minute.
Jimmy: He is a treecko because he is a popular choice and can hold his own. Throughout the game Jimmy has to fight a ton of people who are way stronger (Like Johnny and Damon and etc.) so yeah. He is also a calm and.collected friend if you don't get on his bad side.
Petey: He is a Chikorita because, lets be honest, he's pretty weak. He has the capabilities of the non-clique students and just as strong, which is pretty.much 0 to none. Although he may be weak, he's a character who doesn't lack in the brains section in the slightest. He is a loyal friend to.Jimmy and was there with him all throughout his journey through Bullworth Academy.
Gary: Gary is insane, so charmander works best. He is a strong character who can definitely beat both jimmy and Petey (hence why he's a fire type). He wants to take his spot in the school and rule everybody in it and he'll go to drastic measures. He hates Petey and Jimmy was only apart of his scheme.I
