Quote1 No gangsters would take orders from a little guy they call Mousey! In the underworld, you have to be impressive! So, by posing as a mystery man-- A big man-- I got myself a gang! Mousey, the punk, became Mister X, the big shot! Quote2

  • This version of Mister X, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
