Jock is a Scottish terrier that wears a red toupee, blue sunglasses, and a red-and-white striped shirt. He is Don Karnage's head pilot of the Iron Vulture. He debuted in "A Bad Reflection on You part 2". Karnage often mistakenly calls him Scotty, though Jock eventually tells him otherwise.
Jock is one of the few Air Pirates who is not seen doing any harm to other people, possibly making him a positive person. Most of the time, Jock is seen sleeping.
