Smash Ace
As my current avatar would attest, I love Ristar. I'd love him as a new Sega rep, though I know his kit could be a bit limited based upon his own gameplay but he could be an interesting psudo Dhalsim character with his arm mechanics. He's also one of those characters for Sega that strived to be the mascot before Sonic just rooted himself as such. And he's got loads of tunes I'd love to have brought in/remixed. I wanna head bonk the crap outa people.
