Newly announced for the Ultimate Marvel vs. Capcom 3 roster, Doctor Strange (first vid) and Resident Evil's Nemesis (second vid) are both large-and-in-charge characters that hope to dominate the field, one with supernatural and magical powers and the other with utter brute strength.
Doctor Strange uses his "sorcerer supreme" knowledge to fire all sorts of projectiles at this opponents, whereas Nemesis just roars and crushes his foes with ballistic missiles, tentacles, and powerful punches. So kind of a cross between Iron Man, Hulk, and Venom. Of course, this means that you can create a full team of Resident Evil characters with Wesker, Chris, and Nemesis (and have them actually get along for once).
Expect plenty of more characters to be announced as Ultimate Marvel vs. Capcom 3 reaches its November release date.
