Todd Russell was a U.S. Army soldier who received serious, disfiguring injuries in the line of duty, after which he was used as a guinea pig for experiments by the D.E.O. Treated with a compound similar to that used on Basil Karlo, Russell developed identical powers, but it also erased his memories.
When Todd Russell escaped captivity, he became mentally unstable due to the experimental treatments that he was subjected to. He became so unhinged and self conscious about his appearance that he began killing prostitutes, especially those who looked at his face, in order to satisfy his violent tendencies.
Todd Russell, the seventh Clayface, first appeared in 2002's Catwoman #1, but wasn't fully shown until issue #4 and he wasn't named until Catwoman #44. He was created by Ed Brubaker and Darwyn Cooke.

The One You Love
Two years later, Russell was inadvertently sprung by Catwoman when she stole his container from S.T.A.R. Labs without fully knowing what it was. He later aided her in defeating Hugo Strange's gang by posing as Catwoman and staging her death by getting "killed" by Angle Man.
