Christopher Chance first appeared in “The Assassin-Express Contract”, a backup story written by Len Wein and illustrated by Carmine Infantino that ran in Action Comics #419 (October 26, 1972)
Christopher Chance is the Human Target, a private detective and bodyguard for hire. Master of disguise and all manners of combat training, he is nearly unmatched in skill. Chance will assume the identity of his clients and personally handle any danger when they believe their life is being threatened. Eventually the Human Target became addicted to impersonating clients – even the most unethical ones. He submerged his own personality so deeply that he forgot what it was like. Chance is now incapable of personal relationships, for he is never sure if the emotions he feels are his own, or those of someone he has imitated.
