More than skeptical about whether the game is going to be made or not, I’m skeptical about it being any good. That said, having given up on Marvel long ago, I’m only interested in the Capcom half:
Street Fighter: Would love if they get rid of Chun Li and Akuma, their gameplay has never made sense in Vs series (neither Ryu’s but welp he’s a sure bet). One character that I have always love to see here is Vega: his claw would get the hitboxes it deserves and his walldives and aerial moves are made for this games. Agree that Hugo would make a much better counterpart to the Hulk than Zangief. Other than that, who knows. In the wildest dreams Ingrid also appears as the Capcom OP character to Marvel’s Thanos.
Final Fight: Rolento is another character that would feel at home here. Maki with her tonfas and Cody fighting as dirty as possible would be other good fits.
Darkstalkers: not a problem at all with Morrigan and Felicia, but the males do deserve some love. Jedah is sorely missed and Anakaris would be way more fitting than Dhalsim.
Resident Evil. Sick of zombies here. Leon Kennedy and Claire Redfield would be nice to keep things fresh and Saddler from RE4 as a villain.
DMC. Dante of course and at this point Vergil is too “competitvely iconic” not to include.
Mega Man. Dunno: there’s the whole Inafune debacle and the fact Capconm probably wants to give the game an even more “westerinized” feel than SF (I would say fuck it and let the Japanese be Japanese rather than pretend them to be all about the hot dogs but w/e). Zero would make half the target audience roll their eyes but he’s another iconic character at this point. Other than him, Bass and Mega Man Volnutt feel right.
Others: Never played Monster Hunter, so I can’t say anything about that. Would love to see Captain Commando and Hayato back.
I’d like to see a Spider-Man villain this time around. We know Doctor Octopus got cut from MVC3, and he’s also not around at this point. Green Goblin is no longer Green Goblin, but Carnage is pretty active nowadays with his solo series. I could actually see him being in.
Marvel
5. Ms. Marvel/Warbird (Carol Danvers) - Since Rogue apparently got a lot of her powers from Carol, I imagine she’d have many of the same moves as Rogue did in XvSF, with the addition of energy blasts and stuff.
4. MODOK - Fuck the haters. MODOK rules. I loved barreling into people with his potato face, I can’t wait to do it again.
3. She-Hulk - What can I say, I’m a sucker for the first lady of musclegirls. Hopefully they give her a flashier moveset and restore her to her Vanilla MVC3 glory at the very least.
2. Venom (Eddie Brock) - Venom had insanely cool animations and style. Landing a Venom Web on his opponents and watching him tear them a new chest cavity was extremely satisfying.
Juggernaut - Come on. Don’t you know who the fuck he is?
Capcom
5. Tessa - Buxom witch lady whose movelist lends itself well to MVC. I love her and she’d make a great counterpart to Dr. Strange.
4. Gene - I’ve never played God Hand, I just want him in for his theme song. And I suppose it’d be nice to complete the Clover trifecta (Amaterasu, Viewtiful Joe, Gene).
3. Someone from Power Stone - Could it be Wang Tang? Could it be Gunrock? Or will they choose the least interesting choice, Falcon? I’d be glad to see anyone from it, to be honest.
2. Megaman X - Like I said, keep Classic Megaman in Smash, and give MVC Megaman X. Everyone wins, and his arsenal is more suited to a crazy “screen-filling laser cannon”-type game like Marvel anyways.
Sigma - SO much potential for an amazing character. He could be like a heavyweight version of Dante with the amount of weapons and moves he’d have.
If they could expand the Roster to an even 60 characters (30 per company) that’d be great too.
I like Tron Bonne but not everyone can make the cut. Bass deserves his shot.
They both use weapons but they use different weapons, Claire has a Bow Gun, Stun Gun, and a Grenade Launcher while Leon has a Shot Gun, Magnum and a Flamethrower, Claire would have less health, Leon would deal more damage than Claire at close range but less from a distance (since he mostly uses a shot gun). there’s plenty you can do to make them play differently.
