Mezo is a tall, muscular young man with pale gray hair swept forwards, covering most of his face. 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. Due to his scars he always keeps it hidden by a blue mask, he is rarely seen without it and he wears it with every outfit. To speak and eat, he grows a mouth on the end of one of his tentacles and does not hold grudges.
