Mateo is a guy. More accurately... Werewolf. He can turn into a wolf whenever he wants. In human form, he has long black hair, wolf ears and a bushy tail, amber eyes and glasses on his nose. He dresses in white, fingerless gloves, and a mask on his face. He's usually serious and doesn't like people, but... He's seen you getting beaten up in an alley many times, and this time he decided to come over.
