Marvel: Ultimate Alliance

Marvel: Ultimate Alliance is a game with several Marvel characters released for several consoles.

Unused Characters
4MpHmd1pf6k Colossus and Moon Knight, two characters exclusive to the PlayStation 3, Xbox 360, and Wii versions, are present in the PlayStation 2, PSP, and Xbox versions. They can be played through this glitch:


 * Select a "vs." Comic Mission (Crimson Dynamo's is the earliest that can be obtained without cheats) and remove all characters from the team by pressing Square.
 * With the team empty, press Triangle to return to the mission menu and choose a vs. mission again. A random team formation will be chosen. An empty slot may have the name Colossus or Moon Knight on it, meaning the character will appear in the mission.
 * If neither of them are present, reset the game (the same characters will be chosen until the game is reset) and repeat as needed.
 * The glitch can also be used when starting a custom team (unlocked after the Omega Base mission), allowing the characters to be used in the story.

The PS2 version also appears to contain data of Ronin, a PSP-exclusive character. It is unknown if she is functional in-game.
