History
Grom's history presumably resembles that of his Earth-616 counterpart until the villains became organized, took over the United States, and killed off most of its superheroes.[1] Grom's history after this unknown.
Decades later, Grom and a number of enemies of the Fantastic Four launched an attack on Area 87 where the powerful reality-warping mutant Clyde Wyncham Jr. was being kept in stasis so his powers didn't grow out of control. He placed in stasis by Mister Fantastic, and the villains wanted to kill Wyncham just to spite Richards. However, the villains inadvertently woke Wyncham up. After awakening, Wyncham used his power instantly all of the villains, including Grom.[2]Attributes
