Origin
He along with Gene Bitner, Simon Lestron, and a few others’ mutant powers were used by the Yellow Clawto cause chaos. They were eventually freed from the Yellow Claw’s hypnosis thanks to Suwan and Jimmy Woo of the F.B.I.
Soon later Craig, Gene, and Simon were recruited by Tobias Messenger for his team the Promise. The team would place themselves in suspended animation for ten years at a time and only come out for a week in search for new mutant recruits to join them. Unbeknownst to Tobias and Simon the teaching circuits in place allowed for Simon’s mind to grow essentially giving him the mind of an adult while he was stuck in the body of a child.
X-Men: The Hidden Years
When the X-Men were still fairly new in the world Tobias and the rest of the Promise decided to try and take the newest members of the X-Men, Lorna Dane and Alex Summers unwillingly into their group. Craig was able to use his power called dreamcasting to pit the X-Men against each other making them each appear as monstrous looking creatures to one another which caused them to take each other out. Havok was the only one remaining until Gracie kissed him and used some sort of energy drain mutant power to take him out as well. Since Lorna and Alex had the least connection to Charles Xavier and his beliefs and perceptions of mutants Tobias felt they’d come around to their cause more easily. Lucy Robinson talked Tobias into also taking Warren Worthington III as well. Through the use of “teaching circuits” Tobias had hoped the new recruits would wake up with an understanding of his cause and join willingly after that.
However Lucy was able to rig her and Angel’s suspended animation cylinder causing them to awaken in a much shorter time. She wanted out of the Promise because she believed Tobias has become obsessed with his dream and that he doesn’t care who’s lives he ruins in obtaining his goal. Lucy herself abandoned her family for Tobias’s crusade to save the world.
Eventually Lucy was able to wake up Lorna along with the rest the Promise but suspiciously Tobias wasn’t able to awaken even though his vitals were normal. It’s suggested that Lucy had something to do with it. Simon and the remaining members of Promise decided it best to remain awake and help mutants now before a war that may or may not even happen.
Craig and Gracie decided to adopt Simon in a way since he was still in the body of a kid they thought it better for him to stick with them.
