Early Life

Lockjaw, is the loyal companion of Crystal and the rest of the Inhuman Royal Family. Almost nothing has been revealed about Lockjaw's early history. Apparently, he wasn't a dog but did came up with both animal features and behavior along with teleportation powers.

Fantastic Four

Lockjaw's first encounter with a superhuman from the human world was with Johnny Storm of the Fantastic Four when the Inhumans had left their hidden city in search of Medusa. Lockjaw mistook Johnny for an Inhuman and took him back to their home, where a fight broke out when it was discovered that Johnny was an outsider.[6] The Fantastic Four arrived to help. During the battle it was revealed that the Inhumans were in hiding from another Inhuman known as the Seeker, who in the meantime had arrived in New York seeking the missing Inhumans.[7] Lockjaw and the Royal Family returned to their home land of Attilan, where the reigning king, Maximus, unleashed the Alpha Primitives to combat them. After a brief battle, Maximus realized that he could not hope to win over Black Bolt's courage, and handed the crown of leadership over to his brother.[8]

It's Slobberin' time!!!

While looking for a way to free the Inhumans who had been trapped behind a Null-Zone fieldd, Johnny and Wyatt Wingfoot encountered Lockjaw in the Himalayans. Johnny was happy to have found the creature as its teleportation ability could help them reach the Hidden Land of the Inhumans.[9]

Lockjaw transported Johnny and Wyatt into the Baxter Building instead, where Reed Richards examined his abilities. Lockjaw transported the Fantastic Four to the site of a battle between the original and the new Human Torch orchestrated by the Mad Thinkerr and his computer Quasimodo. Lockjaw teleported them away again when the Thinker's Lab was destroyed.[10]

Johnny and Wyatt traveled the myriad dimensions with Lockjaw in hopes that the beast would eventually transport them beyond the barrier around the Hidden Land.[11] Among other places, they were transported to a world full of dinosaur-like creatures.[12] Lockjaw then transported them back to New York, once more to Johnny's frustration, just in time to battle Doctor Doom.[13]

With the Inhumans free from the Null-Zone barrier, Lockjaw most often served as transportation between their home and New York, often taking Crystal to see Johnny Storm[14] or aiding the Fantastic Four or vice versa.[15][16][17][18][19][20][21]

Incredible Hulk

When Lockjaw encountered the Hulk in a mountain village, the Hulk attacked him. As a reaction, he teleported the Hulk to the dimension where the evil Inhumans had been banished.[22]

Silver Surfer

The Silver Surfer later crashed into the city, but was attacked by Maximus. Believing the all the Inhumans were responsible he battled Lockjaw and the royal family.[23]

When Crystal became ill due to the pollution in the rest of the world and to survive, Crystal returned to the Attilan, transported back home by Lockjaw.[24] They were accidentally transported to a decimate world, but were rescued by the Human Torcch.[25] Lockjaw and the Ben Grimm found themselves in an alternate universe where Reed Richards became the Thing.[26] Lockjaw stayed with Crystal as she nursed the injured mutant Quicksilver back to health.[27][28]

Lockjaw was present during the wedding Crystal and Quicksilver that was crashed by Maximus and Ultron[29] and after they were defeated, transported the married couple to their honeymoon.[30]

Lockjaw was borrowed by the Thing to track a Reed Richards from another dimension who had the same powers as Ben. Lockjaw transported him to another reality, however, to chase after it's local wild life.[31] After a bit of a chase, Ben managed to convince Lockjaw to teleport them to the right dimension, where he helped the alternate Fantastic Four, before Lockjaw brought him home again.[32]

Lockjaw along with the Inhuman royal family were transported away by the Grandmaster along with other heroes of Earth to a specially made arena, where they would battle each other to find the greatest of Earth's Champions.[33]

When Dazzler needed help fighting Absorbing Man she was unable to find any other heroes. Using communications equipment in the Baxter Building, Dazzler got ahold of Medusa and Black Bolt and asked them for help. Bolt arrived with Lockjaw to lend a hand.[34]

Lockjaw attended the naming ceremony of Crystal's baby, along with the FF when the moon was captured by a giant alien.[35]

Lockjaw accompanied the Inhuman Royal Family as they met with the UN Security council, acknowledging their existence to the outside world.[36]

The Thing was at the Mercy General Hospital gift shop buying a trinket for Alicia when suddenly, Crystal of the Inhumans and her pet, Lockjaw teleported inside the room. Crystal was in tears and needed Ben’s help. She begged him to return to Attilan with her to prevent Quicksilver from exposing their daughter, Luna, to the Terrigen Mists.

Lockjaw teleported Ben to Attilan and during the battle between the Ting aand Quicksilver, snatched the child from Pietro’s arms. Ultimately, it was Lockjaw, speaking for the first time in ages, who convinced Pietro to honor Crystal's wishes and not subject Luna to the Terrigen Mists. The Thing was equally shocked to hear the supposed animal speak, as it became apparent that Lockjaw was not really a dog, but rather an actual Inhuman, transformed into an animal by the Terrigen Mists.[5] 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.[37]

The Thing and Lockjaw teleported from Attilan to a small Southern town known as Rock Hollow. They discovered that the residents of Rock Hollow had taken to harassing a poor old woman named Sarah Anne Jackson and her mutant boy Lucas. Several of them gathered around Sarah’s small shack demanding that she turn Lucas over to them. But the arrival of the Thing and Lockjaw kept them at bay. Sarah was grateful for their and provided them with food and drink. Before long however, the crowd returned. One of them shot Lockjaw while another threw a brick through the front window, killing Sarah. Lockjaw teleported into town to warn the Thing. The Thing teleported back to the shack with him, but he was too late to save Sarah’s life. Suddenly, Lucas stepped out of the house for the first time in twelve years. His mutant powers had developed and he generated a wave of calm that dispersed the crowd. After burying Sarah Anne, the Thing had Lockjaw take Lucas Jackson to his new home, the Great Refuge of Attilan on Earth’s moon.[38]

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.[39]

When a mysterious ship crashed near the Blue Area of the Moon, Crystal accompanied by Lockjaw asked the Avengers to investigate.[40]

Heroes Reborn

Lockjaw also traveled to the Counter-Earth with the Royal family. This visit lasted for about a year; all were returned successfully.[41]

The Thing's Pet

Having always been particularly fond of Ben Grimm, Lockjaw elected to stay with him. Ben, fondly recounting that he "always wanted a dog", accepted.[citation needed]

Son of M

After the events of M-day the majority of the mutants on Earth having been rendered powerless, Quicksilver decided to steal the Terrigen Mists and re-power willing mutants. Lockjaw was convinced to help him on the mission. Traveling with Quicksilver's daughter Luna, they traversed the Earth, heading to such places as Genosha. The rest of the Inhumans followed them, to take back the rogue Inhumans and mist.[42]

New Avengers

Later, Lockjaw rejoined the Inhumans and the Avengers in order to assist a superhuman strikeforce in taking down the confused Void (Dark Sentry).[43]

Secret Invasion

During the events the Secret Invasion; Black Bolt was captured and replaced by the Skrulls leaving his former kingdom a prime target to be overtaken.[44] Lockjaw was among the Inhumans who battled the Skrull Infiltrator and exposed him the to Terigen Mist.[45] The remaining Inhuman Royal Family, along with Lockjaw, made a deal with the Kree for their help to rescue Black Bolt from the Skrulls.[46] Lockjaws abilities were enhanced with technology given to the Inhumans by allies of the Kree, which enabled him to increase the distance he could teleport himself and others. With his amped abilities, Lockjaw aided the Inhuman Royal Family in finding and rescuing Black Bolt.[47]

Pet Avengers

When Lockjaw discovered the Infinity Gems, he decided that he would form his own team of heroes to find the lost gems. Joining him were Throg, Lockheed, Redwing, Hairball, and Ms. Lion. Looking for a second gem led them to the Savage Land, face to face with a T-Rex.[48] Zabu arrived and helped them run off the dinosaur. He was invited to join the team. They sensed the location of the next gem in the past so they transported into the prehistoric past and ran into Devil Dinosaur, who happened to be protecting its nest, which inconveniently was the location of the gem. They managed to distract Devil Dinosaur while Lockjaw and Ms. Lion got the gem. They then transported themselves back to the present, only to appear over the open ocean.[49] They crashed into the ocean, but were saved by Namor's Honor Guard turtles, who agreed to help them find two more of the gems. Unfortunately, they were inside Giganto. The turtles fled and Hairball finally freaked out about so much water, waking up Giganto, who swallowed them. Inside, Ms. Lion found the gems, and they teleported away to the location of the final gem, the White House. The final gem was located in the Bo's collar. Bo took off barking out the front door, and the Pet Avengers followed, only to run headlong into Thanos.[50] Thanos, who was the previous owner of the Gems when united as the Infinity Gauntlet, intervened and killed Ms. Lion. The other animals were angered by this act and used the Gems to strand Thanos in an alternate dimension and subsequently revive their comrade. Retrieving the final Gem, the group decided to separate, but not before Throg advised that they now shared a psychic link and would reunite if needed. Ms. Lion resurrected by Hairball via the Soul Gem dubbed the group the Pet Avengers. Lockjaw presented the Gems to a surprised Reed Richards.[51]

Avengers vs. Pet Avengers

The Pet Avengers stopped the robbery of a candy store, and, telepathically recognizing the distress of The The Avengers, teleported themselves to Thor, Captain America, and Iron Man only to find they had been turned to frogs. The villain was none other than Fin Fang Foom followed by a legion of Dragons who then proceed to swallow whole everyone but Lockheed.[52]

With Kamala Khan

After Black Bolt released the Terrigen Mists all over the world, Kamala Khan's Inhuman genes were activated, gaining shape-shifting powers. Having an interest in the girl, Medusa sent Lockjaw to Kamala to keep an eye on the girl.

Powers and AbilitiesEdit


  • Intra/Inter-Dimensional Teleportation: Lockjaw's major power is the ability to teleport himself and up to about one ton of additional mass (including up to a dozen people, if their combined weight does not exceed that limit), across space and even to other dimensions. In order for Lockjaw to teleport another person or object with him, the person or object must stand within a radius of about 14 feet from Lockjaw's body, and preferably be in contact with him. Lockjaw is capable of teleporting himself as little as 10 feet or as far as 240,000 miles (the distance from the Earth to the Moon at its apogee) from his original spot. It is not yet known whether he can teleport himself farther than that. The process of teleportation appears to be psionic in nature and is accompanied by a visible discharge of energy from his antenna. The precise method by which his brain taps the associated psionic energies and harnesses them for use is not known. Lockjaw requires no recovery time after utilizing his teleportation power.[citation needed]
  • Spatial Distance Sense: The means by which Lockjaw can determine distances and spatial relationships between points of departure and arrival, including interdimensional ones, is as yet unknown. Presumably it is associated with or augmented by the use of psionic energies.[citation needed]
  • Psionic/Interdimensional Tracking Sense: Lockjaw also possesses a sense of smell so keen that he can track or locate a scent across dimensional space. Since odors cannot physically travel across dimensions, this ability of Lockjaw's appears to be at least in part an extrasensory (psionic) one, the precise nature of which is as yet unknown.[citation needed] He was stated to be able to teleport by tracking the mental energies of his target.[53]
  • Superhuman Strength: Due to his great size, Lockjaw's jaw is extremely strong. He can also carry 3,600 pounds on his back.[citation needed]
  • Claws: Lockjaw's claws can dig through solid Ferro-Concrete.[citation needed]
  • Superhuman Durability: Lockjaw is much more durable than a human.
  • Telepathic Link: Thanks to the power of the Mind Gem, the Pet Avengers are all telepathically linked with the other.[51]

Strength level

Lockjaw possesses great physical strength simply from size alone. Due to his canine physiology he is limited to what he can pick up by its shape, that is, whether he can hold it with his mouth. His mouth, however, is unusually large, as is his head, which is about 40 inches from flews to dome. His jaw strength is such that he once clamped onto the Thing's hand and the Thing was apparently unable to free it. Lockjaw possesses sufficient strength to support 3,600 pounds on his back and still be able to walk, as well as the power and physical toughness to dig through ferro-concrete with his paws.


Canine Urges: Lockjaw often suffers from canine urges. These often take the form of the desire to chase animals.

Speech Difficulty: Lockjaw can only speak with extreme difficulty.

Limited Manipulative Abilities: Being a canine, Lockjaw can only pick up or otherwise manipulate what he can fit his jaw on.



His teleportation abilities.


Although not being an actual dog,[4][5] Lockjaw is sometimes for one.[55]
