Andy is the main protagonist of the Original Advance Wars Saga. Though young, and naive at times, Andy has a knack for mechanics, and defends his friends.

Fighting for Orange Star, Andy teams up with Max, Sami, and Nell to defend their nation when attacked early on by Blue Moon, and then is a key player in uniting Cosmo Land to combat Sturm and the Black Hole Army. The fact that his units have no strengths or weaknesses, coupled with fact that his CO powers allow him to heal his own units, make him a versatile and formidable CO.
