Death Arms is a very tall, muscular man of a wide build with slightly-tanned skin. He has a square jaw which juts out a notable amount, small eyes and short white hair, spiked out behind his head.
In his hero costume, he wears large headband with a yellow and black-striped caution pattern, matching his thick wrist-guards and the belt around his waist, a square buckle with a triangular decoration sat in its centre. He wears what looks to be a cyan-colored cardigan, which exposes his lower torso and the centre of his pectorals, held onto his chest on each side by small metal nuts. His pants are dark blue, a white stripe down each side, and are slightly baggy on him, and his shoes are plain black with a simple design.
Unnamed Arm Strength Quirk: Death Arms' Quirk grants him a superhuman level of strength in his arms. He is able to lift things that are so heavy, they could normally only be moved via industrial machinery.
