Fictional character biography 
Lockjaw was born on 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.
Seemingly speaking 
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 the 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.[volume & issue needed]
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.
In 2009, Lockjaw received a four-issue mini-series 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 named Throg. The series was well-received enough that there have been two additional mini-series with the Pet Avengers.
Powers and abilities 
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 mini-series, 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.
Other versions 
Earth X 
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.
Marvel Knights 2099 
Lockjaw is one of the few Royal family members to survive to the year 2099; Maximus the Mad had slain the rest. The Inhumans had established themselves on a space station also called Attilan.
Marvel Zombies 
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. Lockjaw is tricked into eating an explosive-laden human brain. He is destroyed in the explosion. Another Lockjaw is seen when the zombie virus spreads to "Earth Z". He too is zombiefied and assists in slaying the "Warbound". He was captured by Machine Man, Ultron and Jocasta.
Ultimate Lockjaw 
Lockjaw also appears in Ultimate Fantastic Four Annual #1. In this incarnation he has teleportation powers as well. 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). Lockjaw assists in saving Crystal from her pursuing guards but they eventually drag her back home anyway. They leave him behind and he brings the Fantastic Four for assistance. This is not well received as most of Inhuman society severely dislikes any outsiders. Black Bolt ends up destroying the evacuated Attilan simply because the Four "contaminated" it. Several of the Inhumans indicate they had conspired for Lockjaw to be left behind in the human world.
In other media 
- Lockjaw appears in the 1994 Fantastic Four animated series. In the episode "Hopelessly Impossible," he helps the Human Torch get the Impossible Man to the Great Refuge and away from the Super-Skrull.
Video games 
- Lockjaw appears as a non-playable hero in the video game Marvel: Ultimate Alliance. His duty was to send the heroes to the Shi'ar galaxy and Skrull homeworld to gather implements necessary to defeating a divinely-empowered Doctor Doom. Also though not there in appearance, the game implies that the mini-portals used in the game for midpoint to home-base transport are made by Lockjaw, since every time the player tries to create a portal outside the circumstances when that is possible, the message "Lockjaw cannot create a portal in that area" appears. This creates somewhat of a continuity error, since when the player gains that ability, it is attributed to an experimental teleportation device created by S.H.I.E.L.D. He also has special "conversations" with Spider-Man, Deadpool, and Thing.
