The character named Greg is a bearded Danish mercenary who stands out among his fellow mercenaries due to his ability to survive any situation, often appearing unconcerned about the danger he faces. He provides comedic relief and humor, but his actions frequently lead him into trouble with both his comrades and officers. In all versions of Area 88, Greg is seen piloting two different aircraft: the A-10 in an OVA (Original Video Animation) and the A-4 Skyhawk in a 2004 anime adaptation.
