Hmm... tricky question. I'd probably go with

. Maybe it's just me, but in a game with such creatively designed fighters like

and

, a fighter who literally just punches people comes off as boring. I never like playing as him since I like using aerials when I play Smash and getting gimped at 0 and dying feels cheap, and I never really have fun playing against him either. I particularly can't stand that KO Punch of his; I get that he has **** recovery, but it doesn't feel entirely fair that this one character essentially gets a FS Meter by default when everyone else doesn't. It reeks of special treatment, quite frankly. He's probably the only character that I feel the game would honestly be better if he wasn't in it.
Dishonorable mentions go to

(playing as or against him frankly bores me to death),

/

(she's easily the most tilting character in the game to play against IMO; that tether grab can **** off), and

(one word: Doriyah).
