Alessio Cortez was a Captain of the Crimson Fists Fourth Company known for his pride, stubbornness, and being impossible to kill. It is said that only two bones in his entire body hadn't been broken one or more times. Cortez went missing in action after a battle with Eldar Raiders, and nothing is known of his whereabouts as of late M41. His old friend and brother Marine, Pedro Kantor, remains convinced that Cortez is still alive.
