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.
He wears a red-and-white striped shirt, glasses, and a red hat.
- He is named the same as a Scottish terrier from the Walt Disney film Lady and the Tramp.
