Alloy was the combined giant, humanoid form of the Metal Men and a member of Magog's Justice Batallion. His body consisted of the original Metal Men as follows: Platinum (head), Mercury (left arm), Tin (left leg), Iron (midsection), Lead (right leg), and Gold (right arm).
Along with Magog, Alloy was the only survivor of the Justice Battalion that survived the Kansas disaster following a disastrous attack on the Parasite. In the aftermath, Alloy joined Superman's Justice League and later participated in the battle against the rogue metahumans at the Gulag. He was among those killed from the United Nations nuclear bombing in which his body was blasted in half.
