King Cobra was a powerful gangster from New York who took control of a prison and operated it as a refuge for mobsters. The Shadow and his agents took him down when they used high-grade TNT to blow up the prison.
- This version of King Cobra, 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.
