First appears in Icon #1 (May 1993) – an original character from Milestone Media Comics.
Created by Dwayne McDuffie and M. D. Bright.
Although published and distributed by DC Comics, the Milestone titles took place in a different continuity.
Milestone imprint was discontinued in 1997.
In 1994, the character was involved in Worlds Collide, a month-long crossover between Milestone and DC Comics’ Superman titles.
At the 2008 Comic-Con, DC Comics executive editor Dan DiDio announced that the Milestone Universe and characters would be revived and merged into the DC Universe, as part of an agreement between DC Comics and Milestone Media.
The merger treated the characters as new to the universe, ignoring the previous crossover. Icon, along with Shadow Cabinet, appeared in Justice League of America (vol. 2) #27, written by Dwayne McDuffie.
