Johnny Morely was a US trooper captured by the Viet Cong, and drugged into doing their bidding by Dr. Han. With additional herbs, she gave him the power to transform into an invulnerable giant. Superman rescued him, and they made short work of the Cong.

  • This version of Jonathan Morely (Earth-One), 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.
