Lockjaw is a fictional superhero character in Marvel Comics, first appearing in Fantastic Four #45 (December 1965). He is a giant, teleporting Inhuman bulldog and a loyal companion and protector of the Inhuman Royal Family. Lockjaw was originally born in the Inhumans' secret city of Attilan, where people possess the potential for superpowers through Terrigen Mist. Lockjaw's mother was brought to Attilan as a puppy and experimented on, eventually gestating five puppies through cloned genetic material.

Lockjaw possesses the power to teleport himself and nearby beings or objects anywhere on Earth or the Moon, and even across dimensions. He can also track scents across dimensional space and has superhuman strength and durability. Lockjaw is loyal and brave, often protecting his family in battles, and acts as the Inhuman Royal Family’s mode of transportation.
