that is practically the most powerful thing in shonen battle anime to ever exist. it wouldn't matter if he had the best stand for dodgeball, or even the greatest most powerful Stand to ever exist, because mid way through the fight when all hope seems lost, she'd suddenly have a better one. worse, he is a smug arrogant jerk who is questioning her power and thinks she thinks too highly of herself- he's practically the shonen battle protag's normal prey.
