I think diddy is super dope!
But he is tiny making his range abysmal
Make him bigger, and make dtilt actually kill confirm or combo. He has very low kill power having dtilt up smash would be nice. People can super hard di out and they will be fine.
So all I want to see rn is diddy being bigger, having slight more kill power, and kill confirms with dtitl.

A suggestion i would like is for side b to have the command grab variant and for diddy to actually pick up the banana as a gimmick, to make it function like grabing an item in smash

Make every smash attack have a bigger hitbox.
