yeah, kirby combos you into the 50s with a grab, and unlike other combo characters, he can kill (dair to fsmash goes around shields most of the time)
wario comes in at an angle you can't hit, and dk's a big target for the 1:00 fart. wario does good against all big characters except dedede (dk, bowser, snake, ganon, ike, and c. falcon) dedede and metaknight are his only two real bad matches, and dedede is by far the worst for wario. i think its a really bad matchup, but i might have a scewed opinion because the only warios i play are futile and plan 9
