Peacemaker.

About Peacemaker

Peacemaker is an antihero originally owned by Charlton Comics and later acquired by DC Comics. The Peacemaker, Christopher Smith, first appeared in Fightin' 5 #40 and was created by writer Joe Gill and artist Pat Boyette. In his debut appearance, he was depicted as a pacifist willing to do anything to bring peace to the world. When DC Comics acquired Peacemaker they changed the character, as depicting him as a violent vigilante haunted by the ghosts of his past. Smith's incarnation would later be killed, and though another incarnation of Peacemaker would follow, Smith's incarnation would later be brought back and become a recurring character.
