History of character is unknown.
- enemy of Doctor Mid-Nite
- This version of Mister Nitro (Earth-Two), 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.
