Bio:
Formerly known as Maverick, Agent Zero has been a member of the X-men, team X and took part in the Weapon X program.
He lost his powers during M-day, an event that caused 90% of all mutants losing their powers.
Even without his mutant powers, Zero is an excellent hand-to-hand combatant, a precision marksman, and an expert in covert operations and demolitions.

I took some creative freedom regarding the colours as you can see in the comparison pic below. I didn't like the green so much.
