Fuck ya! My most wanted character and day one main, as expected he shares a lot of simularity to Akihiko and Steve fox from Tekken and persona 4 arena!
Lil Mac is a hardcore Rushdown character who rules the ground, once he goes airborne he turns to shit. He has intense pressure and is a bit of a reverse Lucario, meaning that he gets stronger by dealing damage. Mac has a counter, a parry, an armored corkscrew blow, and his star uppercut. Build up his meter like how Akihiko builds up his cyclone gauge and get a massive finishing blow.
Also, the final boss in Punchout!! Wii was Donkeykong, I'll post a video of me beating the shit out of him someday, it might make Mael cry =P
And the final smash was referred as in Punch Out!! Wii as the Giga Mac. And the idea of meter to get star punch comes from Super Punchout!!
