I really want to see the next one do a legends of gaming super crossover with the existing cast and all these guys from third parties:
Megaman (obs)
M. Bison
Ammaterasu (OMG yes!)
Chocobo with Moogle
Black Mage
Slime (Dragon Quest)
Belmont
Jimmy Lee and/or Billy Lee
Haggar
Yagyu (or the other Contra dude)
Commander Keen (a must)
Space Marine (Doom)
Carmen Sandiego
Duke Nukem (unfortunately is a legend)
Lara Croft (see above)
Tails (and mabye Knuckles as well, anything post Knuckles in Sonic is lame)
Eggman
Spyro the Dragon
Pitfall Harry (ESSENTIAL)
Tecmo Defensive Linesman (Quarterback sack!)
And finally cut a deal with Microsoft in some way to get Banjo-Kazooie and Joanna Dark
Edit - Oh, and the Jouster (from Joust) to get one more early western character in
Edit 2 - Joe Musashi
NiGHTS
Gillus Thunderhead (Sega needs more love)
Ryu Hayabasa (more Tecmo)
Edit - 3 It just occured to me that I completely neglected anything from Hudson/NEC or the Turbografx. Therefore:
Bonk
Bomberman (also, I really shouldn't have left that one out at all!)
The Lode Runner (an icon of my own childhood even if no one elses)
WiiU - Vectorferret
