Mezo is a tall, muscular young man with pale gray hair swept forwards, covering most of his face, and bent downwards at almost a right angle over his eye. He has six arms attached by a web of skin; the arms are very physically strong, and while his Quirk is not in use, only the front two arms have hands, the rest ending in thin stumps. Despite his frightening appearance, Mezo is friendly and gentle and will work nicely with anyone. He is not the type to hold grudges.
