In role-playing games, an alternate character, often referred to in slang as alt, alt char, or less commonly multi, is a character in addition to one's "primary" or "main" player character. Players are generally not secretive about their alternate characters, unless having multiple characters is illegal, or in a role-playing environment where alternate characters might be judged by the actions of the primary character. In games where multiple characters are illegal, enforcement of this restriction can be difficult, especially without specialized tools.
