He's a courier-controller cross. You can't see in the pics, but he has spots on his beard & massive hands
His temperament is a mix of Stalin and Marje Proops, so he's very friendly (mostly!), but very 'assertive' to the point of being a pain when he hasn't bollocked anyone for an hour every day. He also loves to drink, just like a courier, but he's not quite as mental as some people in Broadmoor.
