Antimony is the Amalgam version of DC's Platinum and Marvel's Scarlet Witch.
Antimony is a member of the Magnetic Men. She was built with the most emotion. She is also diamagnetic, therefore she is not magnetic and cannot be controlled by magnetism. Eventually, she and the other Magnetic Men gained sentience, but were soon killed in battle with the Impossible Mod.
Magneto was able to restore their lives. Antimony and the others were given the ability to transform into humans at will. Antimony was given the human name Debbie Walker and the profession of supermodel. Magneto told the Magnetic Men to lives their lives as humans, because he could not bring sentient beings into battle with him and risk another tragedy. The team eventually reformed.
