History
Dr. Morrow was a brilliant scientist that had his lab on a private island. He would become a target of the Skrulls who were mailing out boxes that would emit cosmic rays that were supposed to make humans their slaves. Instead, it mutated Morrow into a giant creature. When the Fantastic Four would arrive on Morrow's island they would clash with him until the Invisible Girl would trap him in an invisible force field. When Morrow would attempt to fire his laser weapon again, it would backfire and knock him out. It would be the Invisible Girl who would recognize Morrow and lead to an investigation to learn that Morrow had been mutated by the same kind of box as they had[1].
Morrows current activities remain unrevealed.
