The Plastic Man of Earth-Twelve was the (unnamed) son of that world's version of the original Plastic Man, who as a child had drunk the same liquid which empowered his father. This version of Plastic Man was wiped from history by the events of the Crisis on Infinite Earths.

  • This version of Plastic Man, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
