A commission for a client. Pacifist diplomat Christopher Smith is the Peacemaker, a man who loves peace so much, he is willing to kill anyone who stands in its way. Peacemaker first appeared in the Fightin' 5 #40 in 1966 published by Charlton Comics. He was part of this team for five issues. Apparently he became popular enough that he was given his own series that lasted five more issues. Peacemaker became one of Charlton Comics biggest heroes.
Peacemaker was acquired by DC Comics along with other Charlton heroes. He was introduced into the DC Universe by means of the Crisis on Infinite Earths maxi-series. Peacemaker made his DC Comics debut in Crisis on Infinite Earths #6 in 1985. In the epic adventure that destroyed DC’s Multiverse, the Charlton characters were revealed to have existed on Earth-four. Their Earth along with Earths one, two, S and X were the only surviving Earths, which ended up converging into a single composite Earth, were the character was given a new origin.
