Lockjaw
Part 1: The Dossier: An At-a-Glance Summary
Core Identity: Lockjaw is the impossibly large, teleporting bulldog-like companion to the Inhuman Royal Family, serving as their loyal protector, primary mode of transport, and a surprisingly sentient friend.
Key Takeaways:
Role in the Universe: Lockjaw is the official teleporter and guardian of the
Inhuman Royal Family, capable of traversing interstellar and interdimensional distances in an instant. He is also a founding member of the
Pet Avengers.
Primary Impact: His teleportation ability is a crucial plot device in countless Marvel storylines, providing immediate transport for heroes in cosmic wars, planetary invasions, and personal crises, making him one of the most powerful and reliable transporters in the entire
Marvel Universe.
Key Incarnations: The fundamental difference between his comic and screen versions lies in the ambiguity of his intelligence. In the
Earth-616 comics, whether he is a sapient being or just a hyper-intelligent animal is a long-running, intentionally unresolved debate. In the
Marvel Cinematic Universe (MCU), he is portrayed more straightforwardly as a deeply loyal but non-sapient animal companion.
Part 2: Origin and Evolution
Publication History and Creation
Lockjaw first bounded into the Marvel Universe in Fantastic Four #45, published in December 1965. This landmark issue, titled “Among Us Hide… The Inhumans!”, was a product of the legendary creative duo of writer Stan Lee and artist Jack Kirby. His creation was part of Lee and Kirby's explosive expansion of the Marvel cosmos during the Silver Age of comics. They were moving beyond street-level heroes and into grand, mythological science fiction. The Inhumans were a secret race of super-powered beings, hidden away from humanity, and Lockjaw served as their perfect, bizarre, and awe-inspiring introduction.
Kirby's design for Lockjaw is iconic and utterly unique: a gargantuan bulldog, so massive he dwarfs a grown man, with a distinctive tuning fork-like antenna protruding from his forehead. This antenna was a classic Kirby visual motif, signaling a character's connection to cosmic energies or psionic powers. Lee's writing imbued him with a personality that was simultaneously that of a loyal family pet and a mysterious, immensely powerful entity. This combination of the mundane (a dog) and the cosmic (a universe-hopping teleporter) made Lockjaw an instant fan favorite, embodying the imaginative spirit of 1960s Marvel.
In-Universe Origin Story
The true nature of Lockjaw's origin has been one of the most debated and retconned mysteries in Marvel Comics history, creating a rich tapestry of conflicting accounts that only adds to his mystique.
Earth-616 (Prime Comic Universe)
Lockjaw's origin is deliberately shrouded in ambiguity, centered on a single, fundamental question: Is he a dog who gained powers, or was he once a person?
Initially, Lockjaw was presented simply as the Royal Family's pet, an Inhuman animal (similar to how dogs or horses exist for humans) who had been exposed to the transformative Terrigen Mists and granted his signature teleportation abilities. For years, this was the accepted status quo. He behaved like a very intelligent and powerful dog, and no one questioned it.
The major twist came in The Thing #3 (1983). In a moment of frustration, Quicksilver, who was married to the Inhuman princess Crystal at the time, claimed to have discovered the “truth.” He alleged that Lockjaw was, in fact, an Inhuman who, like many others, had been mutated by the Terrigen Mists into a grotesque, non-humanoid form. He feared a similar fate for his own daughter, Luna. This “revelation” sent shockwaves through the fan community and was treated as canon for over a decade. It reframed Lockjaw not as a pet, but as a tragic figure, a sentient being trapped in a canine form.
However, this dramatic origin was eventually retconned. In X-Factor #71 (1991), it was revealed that Quicksilver's claim was based on a lie. The Inhumans Gorgon and Karnak later confessed to having played a cruel prank on their perpetually arrogant brother-in-law, knowing he would believe it. Subsequent stories, such as the limited series Lockjaw and the Pet Avengers and All-New Inhumans, have strongly reinforced the idea that Lockjaw is indeed a canine of Inhuman origin—an animal who underwent Terrigenesis—not a transformed humanoid. The 2017 Lockjaw miniseries further supported this by introducing his biological siblings, confirming he was part of a litter. Despite this, the “was he a man?” question remains a popular piece of trivia and a testament to the character's enduring mystery.
Marvel Cinematic Universe (MCU)
Lockjaw made his live-action debut in the 2017 ABC television series Marvel's Inhumans. In this continuity, his origin is significantly simplified and presented without the comic's long-standing ambiguity.
Within the MCU, Lockjaw is definitively an animal. He is the loyal companion of Crystal and the official teleporter for the Royal Family of Attilan. His origin is not explored in depth, but it is implied that he is a unique Inhuman creature, born as he is, whose teleportation ability is natural to his species or was granted via a controlled Terrigenesis process intended for animals. There is absolutely no suggestion that he was ever a humanoid Inhuman.
His role in the series is pivotal. After Maximus stages a coup on Attilan, Lockjaw is tasked by Black Bolt with teleporting the Royal Family to safety on Earth. In the process, he is stunned by Maximus's subordinate, Auran, and teleports himself to Hawaii, accidentally scattering the rest of the family across the island of Oahu. He is then struck by a civilian vehicle and taken in by a compassionate Earthling named Dave. His recovery and reunion with Crystal form a significant subplot of the series, as his inability to teleport leaves the Royal Family stranded and vulnerable.
The adaptation in the MCU serves a clear narrative purpose: to streamline a potentially convoluted backstory for a television audience unfamiliar with decades of comic book retcons. By presenting him as a super-powered but fundamentally animal companion, the showrunners made him an immediately understandable and sympathetic character without the baggage of his sapience debate.
Part 3: Abilities, Equipment & Personality
Earth-616 (Prime Comic Universe)
Lockjaw's abilities make him one of the most potent non-combatants in the Marvel Universe, with a power set that is both simple in concept and nearly limitless in application.
Powers & Abilities:
Inter/Intra-Dimensional Teleportation: This is Lockjaw's signature power. The tuning fork on his head is believed to help him focus this psionic ability.
Range: Virtually unlimited. Lockjaw can teleport himself and others anywhere on Earth, from one side of a room to the other, or across the galaxy from Earth to the Kree or Shi'ar empires. He can traverse dimensions, having entered the
Negative Zone,
Asgard, and various other realities.
Capacity: He can carry a significant number of passengers, typically the entire Inhuman Royal Family and a few guests, along with cargo if needed.
Mechanism: The process is nearly instantaneous. He seems to require a vague sense of his destination, but his power often exhibits a precognitive or instinctual element, taking him exactly where he needs to be, even if he hasn't been there before.
Superhuman Strength & Durability: As a creature weighing over a ton, Lockjaw is immensely strong and tough. His jaw strength is incredible, capable of chewing through thick steel. He can withstand tremendous physical impacts and energy blasts that would kill a normal creature.
Matter Ingestion: Lockjaw has a famously robust digestive system. He has been seen eating and seemingly digesting everything from enormous quantities of food to entire robots and pieces of scrap metal with no ill effects.
Enhanced Senses: Lockjaw possesses a sense of smell so powerful it can operate on an interdimensional level. He can track specific individuals or objects across vast cosmic distances, a feat he has used multiple times to locate lost allies.
Precognitive Sense (Speculative): On many occasions, Lockjaw has appeared at a precise location just in time to save someone or alter the course of an event, without any obvious instruction. This has led to speculation that he possesses a low-level form of precognition or “cosmic awareness” that guides his teleportation instinct.
Personality & Intelligence:
Lockjaw's true level of intelligence is the character's central enigma. He is fiercely loyal, brave, and generally good-natured. While he most often exhibits the behavior of a very smart and affectionate dog—enjoying head scratches, playing fetch, and responding to commands—there is overwhelming evidence of something more.
Evidence of Sapience: He understands complex, multi-step verbal commands and abstract concepts. As a leader of the Pet Avengers, he formulated strategies and communicated effectively with his animal teammates. In one memorable instance in
Thing #3, he telepathically projected four words to
Ben Grimm: “I like you, Ben.” While this could be attributed to a temporary telepathic link, it remains a key piece of evidence for his supporters.
Ambiguity: Ultimately, Marvel writers have kept his status deliberately vague. For every moment of profound intelligence, there is another where he is happily chasing a ball. He is best understood as a being with an intelligence that defies human classification—part animal instinct, part cosmic wisdom, and wholly unique.
Marvel Cinematic Universe (MCU)
The MCU's Lockjaw is a more grounded, though still fantastical, interpretation. His abilities are visually spectacular, but his personality is clearly defined.
Powers & Abilities:
Teleportation: His primary ability is visually represented by a shimmering, blue, crystalline energy effect that envelops him and his passengers before they vanish. The range is shown to be at least from the Moon to Earth. Unlike the comics, his power in the show is depicted as something that can be exhausted or disrupted. Physical trauma, like being hit by a car, was enough to incapacitate him and temporarily disable his teleportation ability.
Enhanced Durability: He is shown to be incredibly resilient, surviving a direct impact from a car that would have been fatal for any normal animal. However, he is not invulnerable and required time and care to recover from his injuries.
Strength: While not explicitly tested, his size (stated to be 2,100 lbs) implies superhuman strength.
Personality & Intelligence:
In Inhumans, Lockjaw's personality is that of a highly intelligent and exceptionally well-trained animal, but an animal nonetheless. He is deeply bonded with Crystal, responding to her commands and affection. He displays clear emotions like fear, pain, joy, and loyalty. There is no hint of the sapience debate from the comics. He is a super-powered pet, and his relationship with the Royal Family is one of master and beloved animal companion. This change removes the mystery but reinforces his role as a source of emotional connection and sympathy for the audience.
Part 4: Key Relationships & Network
Core Allies
Crystal: His most important relationship. Crystal is his primary master, companion, and handler. Their bond is one of deep, unconditional love and trust. Lockjaw has been by her side since she was a child, and she is the one who most often directs his teleportation. He is incredibly protective of her and will go anywhere and face any danger for her.
Black Bolt & Medusa: As the King and Queen of the Inhumans, Lockjaw serves them with unwavering loyalty. He is their most trusted asset, acting as their royal transport, guardian, and a silent confidant. He obeys Black Bolt's silent commands without hesitation and provides a comforting, stable presence for the entire Royal Family.
Ben Grimm (The Thing): Lockjaw has a special and unusual friendship with the Fantastic Four's ever-lovin' blue-eyed Thing. Ben is one of the few humans Lockjaw seems to have a genuine affection for, often greeting him with slobbery enthusiasm. Their bond was cemented during adventures where Lockjaw acted as Ben's transport and guide, and it was to Ben that Lockjaw once seemed to “speak,” creating a unique connection between the two gruff but good-hearted characters.
Kamala Khan (Ms. Marvel): After Kamala Khan's Inhuman origins were revealed, Queen Medusa assigned Lockjaw to be her protector and companion. The giant teleporting dog became a recurring and beloved member of Ms. Marvel's supporting cast. Their dynamic was heartwarming and often comical, with Lockjaw acting as her loyal steed, a furry shoulder to cry on, and a powerful backup in her early fights.
Arch-Enemies
Lockjaw does not possess personal arch-enemies in the way a traditional superhero does. His enemies are the foes of his family and allies.
Maximus the Mad: As the primary antagonist to the Inhuman Royal Family, Black Bolt's brother has frequently been Lockjaw's main adversary. Maximus's schemes often involve attempting to neutralize, control, or exploit Lockjaw's teleportation abilities. Lockjaw has been instrumental in thwarting Maximus's coups and escaping his traps on numerous occasions.
Thanos: During the
Infinity storyline, Thanos and his Black Order launched a devastating assault on Attilan. Lockjaw was on the front lines, using his powers to evacuate Inhuman citizens and teleport warriors into strategic positions. He stood in direct opposition to one of the universe's greatest threats, proving his courage and value in a galactic-scale conflict.
Affiliations
Inhuman Royal Family: This is his core and defining affiliation. He is not just a pet or a servant; he is an integral member of the family household, present at nearly every major event in their history.
Pet Avengers: Lockjaw was a founding member and the de facto leader of this unique team of super-powered animals. Alongside Throg (a frog with the power of Thor), Zabu (Ka-Zar's sabretooth tiger), Redwing (Falcon's falcon), Lockheed (Kitty Pryde's dragon), and others, he embarked on a quest to collect the Infinity Gems. This role showcased his intelligence, leadership, and heroism outside of his duties to the Inhumans.
Fantastic Four (Associate): Through their long and close alliance with the Inhumans, Lockjaw has become an honorary ally of the Fantastic Four. He has frequently provided them with emergency transport into deep space, the Negative Zone, or other hard-to-reach locations, making him an invaluable resource for Marvel's First Family.
Part 5: Iconic Events & Storylines
First Appearance & The Coming of the Inhumans
In Fantastic Four #45-47, Lockjaw serves as the world's introduction to the Inhumans. When Medusa flees Attilan, Lockjaw and the Royal Family pursue her into the outside world, leading to a direct confrontation with the Fantastic Four. Lockjaw's sudden, silent appearances and his immense power were a source of profound mystery. He single-handedly defeated the Thing and the Human Torch before the two groups eventually allied. This storyline established him as a being of immense power and the loyal gatekeeper of the Inhuman race.
War of Kings & Realm of Kings
This 2009 cosmic crossover event saw the Inhumans, having taken control of the Kree Empire, go to war with the Shi'ar Empire, led by Emperor Vulcan. In a conflict spanning galaxies, Lockjaw's role was elevated from transport to a critical military asset. He acted as a one-being rapid deployment system, teleporting entire squads of Inhuman soldiers for surprise attacks, extracting key personnel from collapsing warships, and maintaining a communication line across the vast battlefield. His power was a deciding factor in several key engagements, demonstrating his strategic importance on a cosmic scale.
Infinity
When the Avengers left Earth to fight the Builders, Thanos saw his opportunity to attack. His primary target was Attilan, where he believed his secret Inhuman son, Thane, was hiding. As Thanos's forces descended, Lockjaw became the key to the Inhumans' survival. He executed a mass evacuation, teleporting the population of Attilan to safety moments before Black Bolt unleashed his voice and leveled their city. Throughout the event, Lockjaw continued to serve the Inhumans in their resistance against the Black Order, once again proving his bravery under the most extreme pressure.
Lockjaw and the Pet Avengers
This series of miniseries gave Lockjaw his first true starring role. After learning of the existence of the Infinity Gems, Lockjaw is tasked by the Medusa of a pocket dimension to assemble a team to find them. He travels the world, recruiting other animal heroes. The series is lighthearted but treats its characters with respect. Lockjaw is portrayed as a wise and capable leader, communicating with the other animals and formulating the plans that lead them to success against foes like Fing Fang Foom and even Thanos. It's a definitive storyline for anyone interested in the “sapient Lockjaw” theory.
Part 6: Variants and Alternative Versions
Ultimate Universe (Earth-1610): Lockjaw appears in the Ultimate Fantastic Four annual as a member of the Ultimate Inhumans. His appearance and powers are largely identical to his Earth-616 counterpart. He serves the same role as the Royal Family's teleporter and is shown to be fiercely protective of Crystal.
Marvel Zombies (Earth-2149): A horrifying version of Lockjaw exists in the Marvel Zombies universe. After being infected with the zombie plague, he retains his teleportation abilities. He becomes the primary mode of transportation for the zombified superheroes, “BAMPFing” them across the globe and eventually to other universes in their unending search for living flesh to consume, making him partially responsible for the plague spreading across the multiverse.
Age of Apocalypse (Earth-295): In this dark, alternate reality ruled by Apocalypse, the Inhuman Royal Family were not reclusive royalty but rather loyal agents of the alien Shi'ar Empire. They were killed by Apocalypse's son, Holocaust, and Lockjaw is presumed to have died with them, as he is not seen in this timeline.
Marvel's Avengers (Video Game, 2020): Lockjaw appears in the main campaign of the Square Enix video game. When a young Kamala Khan is on the run, she finds sanctuary with the “Inhuman Resistance,” where Lockjaw is a comforting presence. He is depicted as a large, gentle companion and later provides a crucial teleport for Kamala, helping her on her journey to reassemble the Avengers. His design is faithful to the comics, and he serves a similar role to his time in her solo comic series.
