Picture it: the sky over Attilan splits open with a crack of displaced air, and a 2,000-pound bulldog materializes out of thin blue light, carrying the entire Inhuman Royal Family on his back. No portal device. No magic spell. Just a massive, wrinkly canine who happens to bend space itself. That's Lockjaw — and he's only the beginning of Marvel's surprisingly deep roster of dog characters.
Most fans can rattle off every Avenger, every X-Man, every Spider-variant in the multiverse. But ask them to name a single marvel comics dog and you'll get blank stares. That's a shame, because Marvel's canine characters have been quietly doing some of the most creative heavy lifting in the publisher's universe for over sixty years. These aren't mascot throwaways or one-panel gags. They're teleporters, hellhounds, tactical partners, and emotional anchors — and their collectors know it.
This piece is the deep cut you didn't know you needed. We're covering every significant dog in Marvel continuity, their actual power sets, the issues that matter for collectors, and a few misconceptions that need correcting (yes, we're talking about Redwing).
Lockjaw — The 2,000-Pound Teleporting Bulldog Who Carries the Inhumans
Let's start with the one that started it all. Lockjaw first appeared in Fantastic Four #45, cover-dated December 1965, created by Stan Lee and Jack Kirby during their most fertile creative stretch. He was introduced as a companion to Crystal of the Inhuman Royal Family, and from issue one, he was never just a pet. The Inhumans relied on him as their primary means of long-distance transportation — a living teleportation engine with the body of an English Bulldog scaled up to roughly the size of a minivan.
Powers That Go Way Beyond "Big Dog"
Lockjaw's signature ability is teleportation. He can open dimensional portals and transport himself and passengers across vast distances — the Official Handbook of the Marvel Universe #6 (1983) lists his effective range at approximately 2,000 miles, though he's demonstrated interdimensional travel on several occasions, including jumps between Earth and the Moon's Blue Area. He can carry up to six adult passengers plus cargo without visible strain.
But teleportation is only part of the kit. Lockjaw possesses:
- Super-canine strength — Class 5 estimated. He's tackled the Thing and held his ground.
- Enhanced durability — His hide resists energy blasts and extreme temperatures. He's survived direct hits from Kree weaponry.
- Dimensional sensing — Lockjaw can track interdimensional energy signatures, essentially sniffing out portal paths that no instrument can detect.
- Near-human intelligence — He understands complex commands, emotional nuance, and tactical situations. Whether he technically qualifies as sapient has been debated in-universe and among fans for decades.
The Tuning Fork Question
One detail that trips up casual readers: the tuning-fork-shaped antenna on Lockjaw's forehead. Some early fan theories suggested it was an artificial implant that granted his powers. Marvel eventually addressed this directly — it's a natural physiological feature of his species, not technology. The Official Handbook entry makes this clear, though the confusion persists in fan wikis to this day.
"Lockjaw's loyalty isn't programmed or commanded. He chooses who he protects. That's what separates him from every other super-powered creature in the Marvel stable." — Comics Beat, "Inhumans at 50: The Legacy of Attilan's Greatest Creation" (2015)
Key Appearances Every Fan Should Read
If you're building a Lockjaw reading list, these are the essential arcs:
- Fantastic Four #45–47 (1965) — First appearance and introduction to Inhuman society. Crystal and Lockjaw's bond is established immediately.
- Inhumans Vol. 1 #1–12 (1975–1977) — The Neal Adams / Doug Moench run. Lockjaw gets significantly more panel time and character development here than anywhere else in the Bronze Age.
- Quasar #14–16 (1990) — Lockjaw is revealed to have been an Inhuman all along (or so the story suggests), adding a layer of tragic identity to the character.
- Silent War #1–6 (2007) — Lockjaw plays a central tactical role in the Inhumans' war against the Kree Empire. His teleportation is weaponized at a strategic scale.
- Inhuman Vol. 4 (2014–2015) — Charles Soule's run integrates Lockjaw into the broader Marvel Universe as the Inhumans become a major faction post-Infinity.
Outside comics, Lockjaw appeared in 26 episodes of the Marvel's Avengers Assemble animated series (2013–2019) and was a recurring presence in the 2017 Inhumans television series, where the practical effects team had to build a full-scale animatronic for close-up shots. That physical prop later sold at Heritage Auctions for $4,250.
Thori — Thor's Hellhound Puppy With Fire in His Belly
Where Lockjaw is Marvel's elder statesman of canine characters, Thori is the scrappy newcomer with a body count. He debuted in Thor Annual #1 (August 2014), part of Jason Aaron's sprawling God of Thunder saga — one of the most critically acclaimed Thor runs in Marvel history, which ran for 25 issues and redefined the character for the 2010s.
Thori is the pup of Garm, the monstrous hound who guards the gates of Hel in Norse mythology (and in Marvel's Asgard). When Garm is killed during the events of the storyline, Thor discovers a surviving puppy — a small, snarling, fire-breathing hellhound with the same dark fur and ember-red eyes as his mother. Thor takes the pup and names him Thori, a diminutive play on his own name. It's a surprisingly tender moment in an otherwise brutal arc.
What Makes Thori Dangerous
Despite being a puppy, Thori inherited a frightening arsenal from his mother:
- Hellfire breath — Not regular fire. Asgardian hellfire burns through magical barriers and can damage beings that are immune to conventional flame, including certain demons and enchanted armor.
- Supernatural speed and agility — Thori moves like a shadow. Even as a juvenile, he's faster than most Asgardian warriors in full sprint.
- Dimensional tracking — Inherited from Garm's role as Hel's gatekeeper. Thori can sense and follow beings across dimensional boundaries, which makes him invaluable for pursuit scenarios.
- Rapid maturation — Asgardian hellhounds age faster than mortal dogs. By his third appearance, Thori had already doubled in size.
The character only appeared in a handful of issues — Thor Annual #1, scattered issues of Thor: God of Thunder, and a brief cameo in War of the Realms tie-in material (2019). But Thori has a cult following among Thor fans precisely because he represents something rare: a moment of genuine warmth in Jason Aaron's otherwise grim Asgardian saga. When Thor is at his lowest — unworthy, depressed, drinking — Thori is there. A hellhound puppy sitting at the feet of a broken god. That image stuck with readers.
The Wider Kennel: Other Canine Characters Worth Knowing
Lockjaw and Thori get the spotlight, but Marvel's universe has room for more dogs than you'd expect. Here are the ones that deserve attention:
Kree Sentry Dogs and Universal Inhumans
During Jonathan Hickman's FF run (2011–2012), the concept of Universal Inhumans was introduced — Inhuman populations seeded across multiple alien races by the Kree. Among these were canine Inhumans from various species, each with distinct Terrigen-triggered mutations. These weren't one-off background details; Hickman used them to underscore the scale of the Kree's genetic experimentation program. The Universal Inhuman dogs appear primarily in FF #7–8 and the Infinity event tie-ins.
The Wolf of Asgard — Fenris and His Legacy
While not strictly a "dog," the Fenris Wolf occupies the canine-adjacent space in Marvel's Asgardian mythology. Fenris has appeared as a recurring antagonist since Journey into Mystery #112 (1965), and his offspring — including Garm, Thori's mother — carry the wolf bloodline into Marvel's canine roster. The distinction matters for collectors: issues featuring Fenris tend to command higher prices than standard Thor villain appearances because the character bridges Marvel and Norse mythology in ways that attract crossover interest.
Bullet — The Punisher's Four-Legged Partner
Here's one that even dedicated Marvel readers often miss. In The Punisher Vol. 5 #31–37 (2002), Frank Castle temporarily partners with a trained attack dog named Bullet during a particularly bloody campaign against a trafficking ring. Bullet isn't super-powered. He's a German Shepherd with military training, and his inclusion was praised by readers and critics for adding an emotional dimension to Castle's character that human companions rarely achieve. Garth Ennis, who wrote the arc, has spoken about using the dog to show a sliver of vulnerability in a character defined by his emotional armor.
Bullet didn't survive the arc. (Ennis doesn't do happy endings for animals.) But the issues remain some of the most sought-after from that volume, with CGC-graded copies of #31 selling in the $80–$120 range as of mid-2025.
Lockheed — Honorable Mention (Not a Dog, but Family)
Shadowcat's companion Lockheed gets brought up in every "Marvel pets" conversation, and it's worth addressing here: Lockheed is a dragon, not a dog. He's a small, purple, Flerken-adjacent space dragon who bonds with Kitty Pryde in Uncanny X-Men #166 (1983). Including him in a dogs list would be a disservice to both the character and the reader. But he matters contextually — Lockheed proved to Marvel editors that non-human companions could drive readership and emotional engagement, which indirectly opened doors for characters like Lockjaw to get more prominent treatment in later decades.
The Redwing Problem: Marvel's Most Misidentified Sidekick Animal
This needs its own section because the confusion is so widespread it's become a meme in comics communities. Redwing, Sam Wilson's (the Falcon) animal partner, is not a dog. Redwing is a red-tailed hawk — a raptor, a bird of prey, an actual falcon. He first appeared in Captain America #117 (September 1969) and has been a bird in every single canonical comic appearance since.
The confusion stems from the Marvel Cinematic Universe, where the Disney+ series The Falcon and the Winter Soldier (2021) and earlier films depicted Redwing as a drone — a high-tech UAV that Sam Wilson controls remotely. That's a completely different thing from the comics' telepathically-linked hawk, and it's caused a generational split in how fans perceive the character. Search "Redwing Falcon dog" on any platform and you'll find thousands of results from people who've never read the source material.
For the record: Marvel Comics has never depicted Redwing as a canine. Not in main continuity, not in alternate universes, not in What If? specials. If you're collecting Falcon-related comics for animal sidekick content, you're getting a hawk — which, honestly, is way more interesting than another super-dog.
Collector's Guide: Marvel Comics Dog Issues and Market Values
If you're hunting marvel comics dogs issues for your collection, here's the landscape as of early 2026. Lockjaw first appearances anchor the market, but there are sleeper picks across the board.
| Issue | Character(s) | Significance | Est. Value (CGC 9.0+) |
|---|---|---|---|
| Fantastic Four #45 | Lockjaw | First appearance of Lockjaw and the Inhumans | $2,500 – $8,000+ |
| Inhumans Vol. 1 #1 | Lockjaw | First solo series; Neal Adams cover art | $150 – $400 |
| Thor Annual #1 (2014) | Thori | First appearance of Thori the hellhound | $15 – $35 |
| The Punisher Vol. 5 #31 | Bullet | First appearance of Bullet; Ennis / Dillon | $80 – $120 |
| FF #7 | Universal Inhuman dogs | Hickman's Universal Inhumans debut | $8 – $20 |
| Silent War #1 | Lockjaw | Lockjaw as strategic weapon; David & Linsner | $5 – $15 |
| Values based on recent eBay sold listings and GoCollect data as of Q1 2026. Actual prices vary by condition, pressing, and label notes. | |||
The obvious takeaway: Fantastic Four #45 is the holy grail for Marvel dog collectors, and it's not even close. But the sleeper pick is The Punisher #31 — Garth Ennis's run is being reassessed by the market as one of the definitive Punisher eras, and Bullet's arc adds a unique emotional dimension that attracts crossover collectors from the military/working-dog niche.
On the merchandise side, Lockjaw has seen a resurgence in vinyl figures since 2023. Funko Pop's Lockjaw (Marvel #657) retailed at $10.99 and now trades in the $35–$55 range on secondary markets. Diamond Select's 10-inch Lockjaw statue from their Marvel Select line (2018) originally retailed at $49.99 and currently commands $85–$120, with sealed-in-box copies hitting $150 on eBay. Thori merchandise remains sparse — a single Hasbro Marvel Legends figure was announced at San Diego Comic-Con 2024 but hasn't shipped as of this writing, which has driven pre-order prices to nearly double the $24.99 MSRP on third-party sites.
Why Marvel's Dogs Hit Different Than DC's
If you're reading this, you've probably already thought about Krypto the Superdog. DC's canine roster — Krypto, Ace the Bat-Hound, Streaky — is more famous by volume, and that's largely because DC leaned into animal spin-off comics decades ago. Krypto the Superdog had its own animated series (2005–2006, 39 episodes), a direct-to-video film, and multiple comic runs aimed at younger readers.
Marvel took a different approach. Their dogs are integrated into the main continuity rather than spinning off into kid-friendly sidebooks. Lockjaw is woven into Inhuman politics, intergalactic warfare, and Royal Family dynamics. Thori exists within Thor's mythological saga. Bullet exists in the Punisher's war on crime. These dogs live in the same violent, complicated, morally gray universe as their human counterparts — and that gives them a weight that Krypto's Saturday-morning adventures simply don't carry.
It's worth noting that the DC crossover reference in our topic — Ace the Bat-Hound — has never appeared in a canonical Marvel/DC crossover comic. Ace debuted in Batman #92 (1955) and has been a DC exclusive ever since. The idea of a Lockjaw vs. Ace matchup is pure fan speculation, and honestly, it wouldn't be much of a fight. Lockjaw teleports. Ace is a German Shepherd with a Bat-mask. We love him, but the power gap is enormous.
Frequently Asked Questions About Marvel Comics Dogs
Can Lockjaw actually talk?
No, not in the traditional sense. Lockjaw communicates through body language, expressions, and a limited set of vocalizations that his companions understand contextually. Crystal and Medusa interpret his intentions with high accuracy, and long-time readers can pick up on his cues too. In Quasar #15 (1990), there's a brief moment where Lockjaw appears to speak a single English word through a telepathic relay, but this has never been repeated and is generally treated as an anomaly rather than a canonical power.
Is Lockjaw a mutated dog or an Inhuman who was transformed?
This has been one of Marvel's longest-running fan debates. In Quasar #14–16, writer Mark Gruenwald suggested that Lockjaw was actually an Inhuman who had undergone Terrigenesis and ended up in a canine form. However, subsequent writers — including Paul Jenkins in Inhumans Vol. 3 (2000) and Charles Soule in Inhuman Vol. 4 (2014) — have treated Lockjaw as a genetically enhanced canine companion, which is the interpretation most current Marvel reference materials use. The Official Handbook of the Marvel Universe: Inhumans (2007) lists him simply under "Inhuman Royal Family companions" without clarifying origin, which is probably intentional.
How many issues has Lockjaw appeared in?
Lockjaw has appeared in over 200 comic book issues across Marvel's publishing history, including main-story appearances, cameos, flashback sequences, and alternate-universe variants. His most concentrated runs are in the various Inhumans series and Fantastic Four tie-ins. He also appeared in the Marvel Knights line, the Secret Wars (2015) event, and the Death of the Inhumans limited series (2018).
Will Thori get his own series?
As of mid-2026, Marvel has not announced a solo Thori series. The character's appearances remain limited to the Thor franchise, and his future is tied to the direction of the current Thor ongoing series. That said, the character's cult popularity — particularly on social media platforms where fan art of Thori consistently trends during Thor-related news cycles — makes him a candidate for a limited series if Marvel decides to test the market.
Are there any Marvel dogs I'm probably forgetting?
Almost certainly. Marvel's 85+ year publishing history includes dozens of one-off canine characters that appeared in single issues and were never seen again — background dogs in street scenes, pets belonging to supporting characters, and animals involved in origin stories. But the characters covered in this article represent the ones with lasting impact: the dogs that came back, that grew, that mattered to the stories around them. If you're digging deeper, check the Marvel Super-Heroes anthology series from the late 1960s and early '70s, where several one-shot stories featured canine characters in lead roles during Marvel's experimental period.
