Destructoid.com revealed that the recently released Marvel Vs. Capcom 3: Fate of Two Worlds had the names "Doc Ock" and "Frank" in the game code.
Of course, "Doc Ock" being Doctor Octupus the Spider-Man villain, and "Frank" possibly from Dead Rising.
Apparently, a hacker got into the game and found the two names as part of code. For "Frank," I don't see a "West," but seeing how this name is included with the other video game characters, and not the Marvel characters, seems to add to the case (I was thinking Frank -- Castle!).
As Destructoid notes, this doesn't mean they will be downloadable characters, it could be the developers simply took them out before the game was finished.
Marvel Vs. Capcom 3: Fate of Two Worlds is available now!
