He is A-tier tho lol. but yes his bite is very good for punishing people who are dumb and just hold shield button, it can also kill at the edge. his side-b can be used for recovery and so can his down-b. his up-b may not be that good but u can recover low or high with his side-b. his fart fully charged can kill anyone at 60% or lower depending on where u are on the stage or what character ur using. overall Wario is a solid character with crazy air mobility and devastating combos! I would say his weakness is that he is a short ranged character and doesnt deal well with sword characters -_-
