Killraven

• Also known as

Killraven is a warrior who was born on Earth-691 (the same as the Guardians of the Galaxy), which was attacked and taken over by the Martian Masters. Men were trained to be gladiators and women were used for breeding babies, which were a delicacy to eat for the Martians. It was in the Martian gladiatorial pits, Jonathan Raven earned the moniker, Killraven. Bringing together others looking to overthrow the Martian rule, or at least escape their grip, Killraven forms the Freemen group. Later on, after a plague kills most of the Masters on Earth-691, X-23 comes across Killraven, rescues him, and he makes Earth X his new home.
