I don't pick "mains" in the traditional sense, but these are characters I play as a lot. Lee Chaolan (Tekken) Dante (Marvel vs. Capcom 3) Link (Super Smash Bros) Literally every guest character in Mortal Kombat

Link was my first character in Smash Bros as I love Zelda! Wonderful choice!

Yeah. Lee Chaolan is really fast. I remember almost always losing to him while playing as Kazyua and Heichachi in the arcade mode of 1 and 2. Although my mains were always someone from Mishima Bloodline.
