Eh, Geno isn't exactly the first "first-party" character I'd pick. I'd actually love to, if they could try to see if MS would play nice again, see if they couldn't get either a character from KI into Smash (I'll take Fulgore, please), any of the Battletoads, or some other "wait, HE'S/SHE'S in Smash!?" on the level of Terry Bogard, Joker, and Banjo character; someone that defies all odds (I thought Joker was a pleasant surprise, but then they got my KOF main in there and I'm over here like, "CAN WE GET SOL BADGUY IN SMASH NOW!? WITH GUILTY GEAR MUSIC!?") on who you'd expect to be on the table for DLC characters in Smash. Dante (NOT DONTE, DANTE, CAPCOM!) would also be cool given all of his weapons (that he'd use better than Harem Emblem Bait #8) and the fact that it'd be a cool crossover between Bayonetta and DMC! Either him, and/or Phoenix Wright, who could I think would be cool given his history on Nintendo consoles!
Also, Travis Touchdown. Need I say more?
