Christopher Smith was a diplomat who loved peace so much that he would routinely dress up in body armor, kit himself out with a variety of lethal weapons, and parachute into international trouble spots where he would cause absolute mayhem in order to preserve it.
The Peacemaker participated in the Crisis on Infinite Earths. This version of Christopher Smith ceased to exist following the Crisis, but much of his history is shared by the Christopher Smith of New Earth.
- Peacemaker first appeared as a backup feature in The Fightin' Five, but was later awarded his own title with the Fightin' Five as his backup feature. After five issues, the Five ousted him from his own book once more.
- This version of Christopher Smith (Earth-Four), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985-86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
