Runt is the "muscle" of the meta-human group that inhabits The Voice's mansion. He presents himself as a friendly presence when he is with his roomies and friends but just like them he's no qualms about their aggressive ventures into society. In fact, he revels in them.
Although not directly shown, it is possible that he is either an avid sleeper or secretly acts outside of the mansion walls, as he's been missing in most of the issues.
Little is known about his past and his parents, but it has been stated that his strength surfaced early in his life and his parents violently abused him because of that. He had spent most of his childhood beaten and locked in cages and, because of his strength, had to work like a slave until his eventual escape.
Powers & Abilties
Strength and Agility: He's stated to possess some degree of enhanced athletic ability, specifically heightened strength and agility. Little has been shown to support this, however one punch from him has been enough to break several teeth of an ordinary person.
