Lockjaw

Lockjaw is a massive, teleporting dog who serves as the loyal companion and transport of the Inhuman Royal Family of Attilan. Exposed to the mutagenic Terrigen Mists like all Inhumans, he emerged with extraordinary teleportation abilities, making him an irreplaceable ally to Medusa, Black Bolt, and beyond.

Few Marvel characters have burrowed into fans' hearts quite like Lockjaw, the colossal, tuning-fork-adorned companion who bounded onto the scene in Fantastic Four #45 back in 1965 — a Silver Age gem conjured by the legendary duo of Stan Lee and Jack Kirby. Affiliated with both the Inhumans and the Fantastic Four, Lockjaw has shared countless adventures alongside royalty like Black Bolt and Medusa, making him a fixture in the regal, otherworldly corners of the Marvel Universe for an astonishing six-plus decades. With 258 catalog appearances spanning Fantastic Four, The Inhumans, and FF, and four key issues to his name, he's far more than a supporting player — he's an enduring icon of the Silver Age whose presence signals that something genuinely special is happening on the page. If you haven't spent time with Lockjaw, you're missing one of Marvel's most beloved and surprisingly essential figures.
