What character from a video game do you best recall unlocking?

Mine'd almost be Ness from N64 SSB, but I think really it's Mewtwo from Melee, playing matches all morning, I think it was 700 required. Sun blaring through Window, listening to my ipod, must've been 6th grade, was my step sister's system. It was fly. I love Mewtwo, anyone else? http://ift.tt/1VCajFF
