Dumas is Stephen Forrest Lee, an assassin with the ability to change his physical appearance. The limitation is that he must concentrate while shape-shifting, or his appearance deteriorates. He is the nemesis of Mark Shaw, who is also the bounty hunter known as Manhunter. Shaw eventually killed Dumas. There was also a second Dumas, a Yakuza member who was injected with the DNA of the original and adopted the identity. Mark Shaw later became Dumas and began hunting down other Manhunters. It was revealed that the government brainwashed him into thinking he was Dumas. This makes it unclear if Dumas was ever a real person, or he was just a brainwashed Mark Shaw. Dumas was created by John Ostrander and Kim Yale, first appearing in Manhunter #1. (1988)
