An original character from DC's Milestone Comics imprint, she first appeared in Icon #1 (May 1993) where she was created by Dwayne McDuffie (writer), Denys Cowan, and Mark Bright. 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 proper. The merger treats the characters as new to the universe, ignoring the "Worlds Collide" Milestone/DC crossover of 1994. Rocket reappeared in Justice League of America (vol. 2) #27, written by creator Dwayne McDuffie.
