Felicia

First Appearance: Darkstalkers (Arcade) 

Raised by a nun, Felecia only dreams of stardom and a singing career. She has the grace, agility and claws that fit her species, and even her body language comes off more cat than human. Also, she's the only fighter in MVC2 who goes nude, as everything she's "wearing" just seems to be hair. 

Gambit

First Appearance: Uncanny X-Men Annual #14 

Native to New Orleans, Gambit joined the X-Men and left behind a murky past of crime. He usually does the right thing while also making time with teammate Rogue. Aside from being skilled with a collapsible staff and hand-to-hand combat, he has the mutant ability to take living and non-living things and charge them with concussive energy. The items then explode on impact, with his trademark throwing cards having the force of a grenade.

Guile

First Appearance: Street Fighter II (Arcade) 

A Major in the Air Force, Guile began fighting to avenge the death of his best friend, Charlie. So he fought his way to the top to take down the guilty party, M. Bison, but decided to be the better man and just beat him but spare his life. Occasionally he has a glimmer of hope that Charlie lives, but when not pursuing that he lives with his family. In fact, this ripped master of the sonic boom is related to Ken by marriage, as each is married to one of a pair of sisters.   

Hayato

First Appearance: Star Gladiator (Arcade) 

Known as the main character of Capcom's first 3D fighter, Hayato Kanzaki and the lightsaber rip-off he wields have been largely forgotten. Taking place in 2348, Hayato is out to save the orphanage he grew up in  - and the planet that it's on - from the evil, Nobel prize winner/cyborg Dr. Bilstein. Making the transition from 3D to 2D worked pretty well for Hayato, as MVC2 keeps him in the public eye way more than his dead series does. 

Hulk

First Appearance: The Incredible Hulk #1 

Needing little introduction, Hulk is the raging beast below the surface of innocent nerd, Bruce Banner's psyche. Created from  a freak gamma bomb accident, whenever he loses control of himself, the Hulk comes out, with his limited intelligence and unlimited power. Basically Hulk is as strong as he needs to be, because if he isn't strong enough, he gets angry then gets stronger. On top of that he has an amazing healing factor and is virtually unkillable when Hulked out.   

Iceman

First Appearance: The X-Men #1 

One of the original five X-Men, Bobby Drake has the ability to create ice out of thin air by dramatically reducing the heat in the immediate area. Normally used to throw ice projectiles or make slides out of ice that he and friends travel on, his powers seem good but limited. However, it's been recently pointed out that he is one of the most powerful mutants, with powers that could inflict global climate shifts. Though his life has had ups and downs, the X-Men can always count on his loyalty.   

Iron Man

First Appearance: Tales of Suspense #39 

Featured in a recent film you may have heard of, Iron Man is one of Marvel's top heroes. When an injury led lazy playboy and industrialist Tony Stark to make a life-saving suit of armor, Tony decided to keep on using it to help the world. Unlike most heroes, Iron Man's costume is in a constant state of flux, as improvements and alterations are continually being made, Though flight, strength and energy blasts are a given, who knows what else the cybernetics genius will add to his robo-clothes next.   

Jill

First Appearance: Resident Evil (PlayStation) 

One of the two main characters in the original Resident Evil, Jill Valentine is known the world over as the "master of unlocking." She's equally good with a pistol as she is with a lock-pick, taking down hundreds of Zombies as a member of S.T.A.R.S. She's sorta in the recent RE5, but we'd rather not spoil things. But despite being the enemy of the undead, one of her moves summons them to aid her in MVC2. Has the world gone topsy-turvy?
