After the Gun Devil took over his body, Aki became the Gun Fiend where his hair was let down and his eyes and forehead were covered in dark veins. The barrel and slide of an M1911 was seen sticking out of his face in between his eyes with the gun’s hammer sticking out the back of his head, Aki's left forearm was replaced with an M4. He can no longer speak, and it seems he’s lost all control of his body. And yet, it feels as if a part of him was still there. He just can’t hurt you, even now.
