>>49254283It depends of the kind of story you are writting, but for me the ideal rival should be your bro, not a jerk.
Also he should be as great as you are and have a good character arc and do cool shit. He should not be your bitch even when he loses to you.
He should also look cool and imposing, not a lame faggot like Barry.
The girl rival must a be hot 12 years old girl.
