Regardless of the Meta counter issue, he is a genuine Snake counter, so that's always something to consider. He's fast and powerful, with enormous range (rivaling Snake's) on his tilts and very wide coverage on his smashes. He kills early and takes a lot of damage. His vertical recovery may not be the best, but his horizontal recovery is pretty much ungimpable, and some of the best in the game. His short-hopped B-air has crazy range and is an excellent approach to almost everything. He has loads of Super Armor on a bunch of moves, notably his Up-Special and Neutral-Special (Donkey Punch). His grab is powerful and at higher percents can be used to cargo-throw -> stage spike opponents. His Down-B outranges every ground move in the game, and his F-tilt swats through most projectiles (and MK's tornado). His D-tilt trips and his Side-B stops all momentum as well as spiking and being great for punishing. His U-air is good for juggling some characters, especially Snake. Overall he's a very solid character, marred only by the D3 standing infinite. He'd make a great secondary, although there might be a little too much overlap with Bowser just because they're both heavies.
