Martina Hughes, codename Knockoff, was formerly Marty Hughes. He was the son and only child of the villain Setup and an unknown baseline father. During a hiking trip, he was injured and lost a lot of blood; no blood for his type (O negative) was available at the rural clinic, and his mother donated blood for him. Because she was a regenerator, he healed into a clone of her, and manifested as a mutant, though not with the same powers. She's a Regen-3, PK-2 (flight and PK punches), EX-3.
