Greg Gates

A bearded Danish mercenary, he is noted by the base's mercenary force for being the only person who couldn't die, sometimes apparently oblivious or apathetic to the danger he faces. Greg serves as comedic relief and humor, as his actions lead him to trouble with his comrades and his officers, not to mention unintentionally making the civil war even worse. Pilots the A-10 (OVA), and A-4 Skyhawk (2004 anime), Greg appears in all versions of Area 88.
