Gamers and comics fans alike are rejoicing over the announcement of Marvel vs. Capcom 3, which was long thought lost to the rigours of development hell. No, true believers, MvC3 would not rot beside the Duke Nukem Forevers of this world, and finally see light.
From the teaser trailer, we know that there are six confirmed characters: from Marvel we have Wolverine, Iron Man and the Hulk, while Ryu from Street Fighter, Darkstalkers' Morrigan and Resident Evil's Chris Redfield represent Capcom. There looks to be roughly 30 spots open for other characters, however, and I thought I might take the opportunity to give four more of my fantasy picks, and why they should be there - two from Capcom, two from Marvel.

All right, if we're going to have a fighting game, we may as well have someone who's good at fighting. Iron Fist's modus operandi is to beat the stuffing out of things, and if the game developers are feeling particularly creative, they can have his punches be stronger than his kicks due to the apparently metallic nature of his hands.
Danny Rand will be able to flip around all agile-like, use his chi powers to throw the odd fireball and summon the power of Shou-Lao the undying for an ultimate attack. Add in some sweet combos and some "stances" a la Street Fighter's Gen, and you've got yourself a hell of a powerhouse.

Frank's seen his share of action lately, jumping into the spotlight of two of Capcom's bigger games. Appearing first as a secret character in the Lost Planet sequel and again in another Capcom fighting game (this time versus anime company Tatsunoko), Frank's no stranger to combat.
Really, his character's worked in a fighting game before as somewhat of a joke character. The sheer amount of hammerspace-produced weapons, along with zombie-based attacks leaves Frank a quirky, yet playable character.
Plus, he's covered wars, y'know.

While a little out of left field, I have a good reason for wanting Strange in a Marvel vs. Capcom game: so they can finally have a hero-villain counterpart to the tentacle monster Shuma-Gorath, who has been part of the fighting game series since 1995's Marvel Super Heroes.
A great frustration of mine is when people don't know the origin of the monster; by leaving Strange out, you don't get that explanation. His character wouldn't be hard: a projectile-heavy player who benefits from hanging back and throwing around energy. Hey, Strange has been known to throw a punch or two in his time as well; give him some spotlight!

All right, I know what you're thinking: how would they fit two Ryus on the roster? While that might be a roadblock that Capcom couldn't overcome, I think the Breath of Fire series has been largely cast to the wayside in the legacy of kick-ass RPGs. While licenced for release in the USA by Squaresoft, Breath of Fire 1 was a Capcom production.
True to the story, Ryu is part dragon. A natural swordsman, have one of his ultimates make him shape shift to his dragon form for a little bit. Maybe even give him a fire breath attack or something. You know, because of the title of the game and all.
Ultimately we're just going to have to wait and see what Capcom has in store for us. Hopefully they give us what I and many other comic fans crave: equal representation from the obscure and mainstream characters.
