Biggs is a lean young man with swept-back brown hair and a bandana tied round his forehead. He wears an olive shirt and green three-quarter trousers, brown boots with silver fasteners round the ankle, brown gloves, and two belts: one black and one brown, the latter of which has a pouch on his left hip. Biggs is considered the strategist of the group, acting as a calm contrast to Barret's intensity. Biggs can nonetheless be hotheaded and a bit of a complainer, griping about Barret's strictness as he dozes off on the train. He enjoys drinking, as he is ecstatic over the refreshments Tifa provides for the rest of Avalanche upon their return from Mako Reactor 1, and invites Cloud to partake. Despite his confidence, Biggs is prone to overthinking, particularly when involving his allies, to the point of becoming stressed. He alleviates this by occupying himself with tasks such as cleaning. In Final Fantasy VII Remake it is revealed he enjoys teaching children, and used to be a teacher before joining Avalanche.
