The Secret Six is the name of three different fictional comic book teams in the DC Comics Universe, plus an alternate universe's fourth team. Each team has had six members, led by a mysterious figure named Mockingbird, whom the characters assume to be one of the other five members. The third, anti-heroic incarnation of the Secret Six was rated by IGN as the fourth Best Comic Run of the Decade in 2012.
