Lockjaw is a fictional character and alien bulldog-like being published by Marvel Comics. He first appeared in Fantastic Four #45 (December 1965), and was created by Stan Lee and Jack Kirby.
Lockjaw was born in the Island of Attilan, formerly in the Atlantic Ocean. Lockjaw resembles a giant bulldog and serves in the capacity of the Inhumans' teleporter and escort to the Royal Family of the Inhumans. Many times he has brought Inhumans to Earth and back again. At times, his powers have been manipulated by evil forces, most usually Maximus The Mad.
Lockjaw and the royal family encountered Maximus' creation, the Trikon, and were driven from Attilan's Great Refuge in exile.
Lockjaw first appeared as a member of the Inhumans when they attempted to retrieve Medusa from the outside world and take her back to Attilan. This led them into conflict with the Fantastic Four, the first humans they met, who were harboring Medusa after rescuing her from the villainous Frightful Four. Accordingly, Lockjaw is indirectly responsible for revealing the existence of Attilan to the outside world. They returned to Attilan and became trapped in Maximus' "negative zone" barrier around the Great Refuge.
