Barret is a heavy-set, muscular dark-skinned man with a dirty brown vest, green pants and large brown boots. His right arm was mangled in the loss of his hometown, and has been replaced with his weapon, the gun-arm, which lets him interchange various weapon attachments to it.
Barret has several bands of metal around his waist and his remaining arm, and a tattoo on his left shoulder. His hair is cut similar to a hi-top fade and he has a thick beard and a dog-tag around his neck. He has three scars on his right cheek.
Barret is characterized early in Final Fantasy VII as a brash, gruff man with a short temper and a tendency to curse. He is prone to firing his gun-arm into the air in fits of rage catching the attention of everyone around him. Barret's rage is accompanied by a deeper, albeit rarely shown thoughtfulness.
