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 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.
Lockjaw is able to escape and becomes separated from his city. He roams the country for some time, accidentally terrorizing the local citizens, until he meets up with Johnny Storm and Wyatt Wingfoot. He journeyed with the pair in their attempt to breach the "negative zone" barrier. Before long, the Inhumans were freed from the "negative zone" barrier, and Lockjaw transported Crystal to New York, and brought Triton from Attilan to rescue Mister Fantastic. Lockjaw was later compelled to return Crystal to Attilan by Maximus.
With Crystal, Lockjaw was captured by Diablo. They later rescued the injured Quicksilver. Before long, Lockjaw attended the wedding of Quicksilver and Crystal. He also brought the Fantastic Four to Attilan to battle Thraxton.
At one point, Quicksilver and the Thing witnessed what appeared to be Lockjaw, apparently a sentient being once mutated by Terrigen Mists, speaking to them. This convinces Quicksilver not to expose his daughter Luna to those Mists. However, Lockjaw later brought Quicksilver to Washington D.C. in search of X-Factor, and Quicksilver there stated that Lockjaw's sentience was actually a hoax perpetrated on the Thing by Karnak and Gorgon.
Lockjaw brought the other Inhumans to Earth in search of Medusa when she fled Attilan to avoid a compulsory abortion. He also transported the injured Triton back to Attilan. With Crystal, he later summoned the Avengers to help battle Thane Ector and the Brethren. With the Avengers, he battled the Brethren.
Having always been particularly fond of Ben Grimm, Lockjaw elects to stay with him. Ben, fondly recounting that he "always wanted a dog", accepted. It is not known why Lockjaw did not accompany Ben Grimm when he felt the need to retreat to France during the Civil War.
Lockjaw is featured into the 2006 limited series Son of M. With the majority of the mutants on Earth having been rendered powerless, Quicksilver decides to steal the Inhumans mutagenic Terrigen Mists and re-power willing mutants. Lockjaw is convinced to help him on the mission. Traveling with Quicksilver's daughter Luna, they traverse the Earth, heading to such places as Genosha. The other Inhumans follow.
Lockjaw assists his family tracking down Black Bolt, who had been captured by the Skrulls. Using technology gained from their allies, the Kree, Lockjaw's abilities are upgraded, allowing him to teleport much farther.
It was announced at New York Comic-Con 2009, that Lockjaw would receive a four issue miniseries titled Lockjaw and the Pet Avengers, teaming with Lockheed, Redwing, Ms. Lion (Firestar's puppy from Spider-Man and his Amazing Friends), Zabu, Niels the Cat/Hairball, and a new frog Thor (Throg).
Lockjaw seemingly has "super-canine" strength in his jaw for a dog his age and size. At one time he locked on to the Thing's arm and the Thing could not get him to let go. Lockjaw can also teleport himself, and nearby living creatures and matter to anywhere he wants, from the Earth to the Moon, and can even open passages between dimensions. Energy barriers that are seemingly impenetrable to others seem to pose no problem to him. Lockjaw also has the ability to psionically trace a given "scent" across dimensional space.
Lockjaw is capable of chewing and swallowing inorganic material, such as scraps of sophisticated robots, with no ill effect. It is not known if this is his primary source of nourishment.
In the Secret Invasion: Inhumans miniseries, the Royal family enter into an alliance with the Kree to free Black Bolt from his Skrull captors. To that end, the Kree greatly enhance Lockjaw's teleportation powers, enabling him to teleport himself and others over vast interplanetary distances.
In the alternate future of Earth X, Lockjaw is shot by some gaseous bullet and murdered by Maximus. His teleportation-forehead assembly is seemingly the only part of him that has survived. It is used by Black Bolt and the other Inhumans to investigate happenings on Earth.
Lockjaw appears zombified along with the Royal Family of the Inhumans, creating a portal for them to meet with the Kingpin. He is later seen trying to attack Machine Man. The heroic cyborg tricks Lockjaw into teleporting to the mainstream Marvel Universe. There, a bomb hidden in a human brain destroys Lockjaw.
Lockjaw also appears in Ultimate Fantastic Four Annual #1. In this incarnation he seems to have teleportation powers similar to his 616 counter part (Though the limitation of the powers are not really defined). He leaves the Inhumans' Himalayan refuge with Crystal, who is running away because she was being forced to marry Black Bolt's brother, Maximus (only Crystal suspects he is mad). He is seen teleporting the Fantastic Four to the Inhumans' home. He also seems to be able to telepathically communicate with Crystal. If he can do it with others has still to be seen. After the Fantastic Four discover the city, the Inhumans leave, seemingly relocating to the moon. Several of the Inhumans indicate they had conspired for Lockjaw to be left behind in the human world.
