Wrench

Wrench is a pretty laid back dragon who is deaf. Numbers acts like his translator which is more than he could ever ask of his partner. Though Wrench doesn't speak he's pretty good at conveying what he's thinking through the various expressions that play across his features when he's not trying to be stone faced. He's helping Numbers but little Lester is keeping them from their goal. He doesn't care much for the meek little tundra but wants to make sure to get all the information they need before going after him.
Apart from being the silent intimidating muscle Wrench is actually kind and lovable but no one is able to get close enough to find that out other than Numbers, who he absolutely adores.
