RUBY HEART

Ruby Heart is the protagonist of the game MvC2.

She is a French-speaking pirate who owns the flying ship that is responsible for carrying the Marvel and Capcom heroes into battle. Ruby Heart is looking for the mysterious orb that the final boss Abyss possesses. Once Ruby Heart finally obtains the orb, she doesn't seem very pleased with it, and throws it into the ocean.

It's long been rumored that she was / will be in the next DarkStalker game (if they make a new one), since she was originally planned to be made into a new DarkStalker character by Capcom.

MORRIGAN AENSLAND

Morrigan Aensland is a succubus video game character from Capcom's fighting game series Darkstalkers (or Vampire Savior in Japan.) She appears in Marvel Vs. Capcom 3 alongside Felicia and Hsien-Ko.
Morrigan is very vain, and lives for little more than the excitement of battle, although her endings in the games as well as various media show that Morrigan slowly takes up more of her responsibility seriously. She appears as a beautiful woman with long, light green hair, a very revealing top, and bat-like wings on her back and the sides of her head. Morrigan can reshape these wings into spikes and blades when attacking her enemies, as well as using them to shield herself from enemy attacks. Her wings can also separate from her, and form into a cloud of bats. She uses a variety of magical attacks as well.

n opening 1 Morrigan is seen fighting Ironman and in the mix she hits Deadpool, gets distracted and gets knocked out of the sky by a Unibeam where she is saved by Chris Redfield.

In Morrigan's MvC3 ending, she finds what seems to be a bar where several demons are. This place is implied to be a "small watering hole" that exists between the human and demon worlds and where the strongest demons come here to celebrate. Several characters can be seen here such as Satannish and Mephisto; Satannish claims the best of the best come here to have a drink and get in a good fight and Mephisto is surprised that Morrigan was able to even come here. Morrigan is interested and decides to raises a toast. They raise a toast to the place where darkness can dance and to their new guest, Morrigan.

Morrigan has moves based primarily on Ryu and Ken from Street Fighter. Morrigan's Darkness Illusion was the first super move to use the button press sequence (LP, LP, F, LK, HP) that is now commonly associated with the Shun Goku Satsu. In Marvel vs. Capcom 3, Morrigan gains a more distict style of fighting. She has plenty of options in the air, unlike Ryu or Ken, and is significantly faster then Ryu or Ken. One of the many running jokes (and points of criticism) among fans is that she has had the exact same sprite set as far as Capcom vs. SNK 2 (2001) as she did in the original Darkstalkers (1994). Her sprites looks especially out of place in the Capcom vs. SNK series as they gain a black outline in the borders. Obviously, in Marvel vs. Capcom 3, Morrigan has a new character model in 3D.

LILITH AENSLAND

Lilith Aensland is a character from Darkstalkers. She is a miniature succubus who was created from energy drawn from the succubus Morrigan. This dangerous excess energy was separated from Morrigan at birth by her father, Belial, who sealed it away. The separated energy formed a mind of its own and named itself Lilith.

As she is derived from Morrigan, she shares similar attacks with Morrigan but with some different executions as well. For example, her Soul Flash is a projectile attack like Morrigan's Soul Fist but instead of a ki blast, she summons a shining green bat with hearts resonating around its body that only travels for a short distance. She does have attacks unique from Morrigan, such as her Mystic Arrow where she tosses her enemies across the stage with her wings in the manner of a bow and arrow. She can also have her bats attack in a swarm. She shares Morrigan's ability to transform her clothes into whatever she wants to wear at the moment.

HSIEN-KO

Hsien-Ko (Lei-Lei in Japan) is a video game character from Capcom's fighting game series Darkstalkers (Vampire in Japan). She appears in Marvel vs. Capcom 3 alongside Morrigan and Felicia. She is a jiāngshī, a type of zombie from Chinese folklore.

In Marvel vs. Capcom 3, Hsien-Ko and Mei-Ling try to take advantage of the merging worlds to meet the Sorcerer Supreme of the other world and ask him to save their mother's soul. During her search for Dr. Strange, Hsien-Ko was attacked by heroes who viewed her as an intruder, much to her confusion.

In her ending, the twins finally meet Dr. Strange to make their request. Before Strange agrees, Hsien-Ko asks him if they did something wrong to provoke the attacks from "comic book superheroes." Stephen assures them they did no wrong since they were just trying to save their mother. He proceeds to not only saves their mother, but also makes Hsien-Ko and Mei-Ling human again. However, it is revealed that this was actually a comic book drawn up by Hsien-Ko, while Mei-Ling criticizes its quality.

Originally Hsien- Ko was on the "deconfirmed" list, as an interview with Nitsuma claimed that there would be no more Darkstalkers characters (when in fact this was an error on the translator, as he was only deconfirming werewolf J. Talbain in the original lineup of MvC3), causing her appearance to shock players who had seen the mistranslation.

FELICIA

Felicia is a video game character from Capcom's fighting game series Darkstalkers (or Vampire Savior in Japan.) She appears in Marvel vs. Capcom 3 alongside Morrigan and Hsien-Ko, two other Darkstalker females. Felicia was raised by a Catholic nun named Rose. When Rose died, Felicia left her town hoping to be a musical star. During her travels, she met many other catgirls of her kind. With her newfound friends, she set out for her dream of being on stage. Eventually, she and her friends started a musical with Felicia being the main star.
In the events of Darkstalkers 3, she wondered about how she could make others happy. In her ending, Felicia became a nun herself and founded an orphanage named "Felicity House."

In Marvel Vs Capcom, Felicia was seen with Mike Haggar trying to put out the flames on his "Vote Haggar" sign in the 4th opening. She was helping by blowing it out with her breath. Her tail then caught fire, where she ran around, jumped on Haggar's sign and scratched it with her claws.
On the U.S. website of Marvel vs Capcom 3, Felicia was until recently the only character whose entire body was cut out (the same was more recently done to Morrigan as well), leaving just her head and right hand. This could be due to her body and might have forced the developers of the website to adhere to censorship standards. The same thing goes for Marvel vs Capcom 3's Facebook picture of her. Even in the game's intro, her body is cleverly censored most of the time. Her breasts aren't visible because she is piggybacking on top of Haggar, and her buttocks are hidden at one point by her foot.

BABY BONNIE HOOD

Baby Bonnie Hood also known as B.B. Hood (Bulleta in Japan), is a character from the Darkstalkers series designed by Yoshiki Okamoto. Although she has a cute and innocent appearance (as her name suggests, she physically resembles Little Red Riding Hood), B.B. Hood is a murderous psychopath. As a Darkhunter, she kills Darkstalkers for money. As a homicidal schizophrenic, it is unwise for anyone to stand against her in her pursuit of money. Many look upon her as an antithesis to fellow darkhunters, Donovan Baine and Hsien-Ko.

When creating B.B. Hood, Okamoto stated in his design notes that every Darkstalker character is inspired by something in fantasy, myth, and horror. When creating B.B. Hood however, he wanted to do something a little more sinister. Rather than be based off of an archetype, or a myth, B.B. Hood is inspired by the frightening qualities of the human race itself. When motivated by greed or ambition and fueled by malice, no monster can compare to how terrifying humans can be. This is what B.B. Hood personifies, from her deceptive appearance to her relentless, heartless quest for money. It could even be said that B.B. Hood represents humanity's dark side (she even points it out in her ending in SNK vs. Capcom: The Match of the Millennium: "Violent, stingy, schizophrenic... It sounds... like me!"). These notes were included in the official Japanese strategy guide for Darkstalkers 3.

B.B. Hood's weapons of choice are a seemingly endless number of various armaments that she keeps hidden in her basket. Additionally, she tosses an endless supply of landmines from her pockets. Though a sweet little blonde on the outside, she's a powerful character and is highly psychotic. B.B. Hood is feared by weaker Darkstalkers everywhere.

B.B. Hood's profession was founded because droves of creatures from Makai had already flowed into the human world. Many of these creatures have since earned the interest of humans, be it scientific, prejudice, or simple curiosity. Items usable for decorations, materials that don't exist in the human world (such as the liquid and blood from their internal organs) are of keen interest, especially for research for bio-weapons and such. A "Darkhunter" is a job that was born to meet the demand for these clients.

ANAKARIS

Anakaris is a character from Capcom's Darkstalkers game series. He is the mummy of the twelfth pharaoh of Egypt. Foreseeing his death and revival, Anakaris created a pyramid and a place for his revival. Five thousand years later, he was revived when Pyron came along. In order to rule his kingdom once more, he gathered immense power from battling others and then travelled back five thousand years in time. When his kingdom came to be threatened again, he assumed the form of a mummy again to engage in the battles there. He eventually decided to protect his kingdom by moving it entirely into another dimension.

In the second installment of the Marvel vs. Capcom series, Anakaris makes a surprising selection for the Capcom camp. This incarnation of Anakaris is slightly faster and he maintains most of his Darkstalkers moves, with slight exaggerations. One of his new EX Moves is the Serpent Coffin which is an enhanced version of his Cobra Blow. In this variation Anakaris opens his coffin and releases three to four giant serpents at a time thrusting very fast horizontally.
Anakaris possess the most unconventional array of special moves compared to other characters in the series. The Pharaoh’s Curse, a slow moving air-to-ground projectile, turns the opponent into a small vulnerable icon of their original self for a short period of time. During the transformation, the opponent can only jump or move backwards or forwards. This unique move has been a trademark for Anakaris and has become very popular for Capcom as well. Anakaris also has unique projectile moves, which involve him putting his limbs into an entrance portal and coming out another. This takes a considerable amount of time and leaves a huge blindspot between him and his attacking limb.
