How's it goin? If ya need anything, I'm Gavin.


Gavin grew up in a SHIELD facility where he'd lived since he was born. His mother, Ilyana,was a genetic creation made from the combined DNA of several mutants by SHIELD in an attempt to create their own mutant police force. However, after the formation of the fifty-state inititive, the project was scrapped, but they still made Ilyana reside at SHIELD headquarters in New York. Gavin knew little of his father, other than that his name was Dean MacCallister, and that he was a SHIELD agent. Having never known his father, and always being kept away from his mother, Gavin was essientially raised by a SHIELD agent named Alana Xiao. She raised him as though he was her own son, along with her daughter Alexis. After a while, Gavin began a relationship with Alexis. While celbrating their 1 year anniversary, a secretly sent Sentinel attacked them. In this instant, Gavin's mutant gene activated. In a rage that Alexis was in danger, Gavin lost control of his abilities, causing the Sentinel to explode, being ripped apart on a molecular level. After the attack, Alexis brought him back to her mother, who despite Alexis asking for her help, simply turned him over to SHIELD to experiment on him and analayze his DNA. Miserable, betrayed,and at the mercy of SHIELD, Gavin contemplated suicide when suddenly his mother teleported into his cell with Alexis with her. He embraced her and asked what they were doing there, the entire time staring at Ilyana, though he could not see her face due to the dark hood she was wearing. She only walked up to her son, kissed him on his forehead, smiled, and teleported away. Alexis told him she could get him out of the headquarters, but that he'd need to find somewhere safe. She handed him a brochere for the Xavier Institute and told him he's be safe there. When he asked why she had the brochure, she smiled and walked with him through the walls and outside of the facility. She told him she was a mutant as well, and had attracted the Sentinel that night, and that because of it, had considered going to the institiute, and would come find hom there when she could. He nodded and left for Xavier's. He eventually arrived at the Institute, enrolled, and is currently training to be an X-Man under the codename Ion while waiting to reunite with Alexis.


Complete Molecular Control of Matter. He uses this in a vast variety of ways. He lossens his molecular structure to give him intangibility, condenses it to give near invulnerability. He can also uses his abilities on other matter. He can slow molecular motion to the point of causing objects to stand still, and can accelerate molecular motion to the point of causing explosions, or spontaneous combustion. He can expel small amounts of his own molecules (Usually his fingernails) as projectiles as a weapon. With extreme exertion, he can control the movement of his own molecular structure, exhibiting a teleportation-like ability where he disperses his molecules and reforms them in another location
