Rook might be the toughest tool in the shed but he sure aint the brightest. 

Rook is a tough as nails soldier having served on the elite commando unit known as the wreckers, but he has a soft and caring center. But he is also a hot head often running head first into battle brandishing his hands which he had replaced with guns to make sure he's never caught off guard, but unfortunately this often causes him to get himself into some sticky situations which his mates have to get him out of. 

Rook has a soft spot for organics even spending some time as a search and rescue operator on organic worlds, which often makes him the butt of many jokes form his fellow wreckers. 

Note: This role is not just limited to this project and actors will be needed to appear in multiple projects
