River Rat grew up on the mighty Mississippi. His father and grand father were river boat captains. River Rat knows the inner workings of any river and can navigate a path of least resistance for him and his fellow brothers in arms. He is an expert marksman when it comes to wild game. His steady hand and cool thinking in battle have saved more lives than not. He lives in his armored boat called "Grace" that also serves as the Joes' water communications base. Either on land or on the river, River Rat demands respect for him and his boat.
