Lockjaw serves the Inhuman Royal Family, wielding the power of teleportation. He instantly transports individuals across vast distances, including between Earth and the moon-based city of Attilan, accompanied by a bright flash of light. This ability becomes crucial when Terrigen Mist exposure triggers superpowers in humans, escalating tensions between Earth and the Inhumans. Lockjaw facilitates the Avengers and Future Avengers' movement between Earth and Attilan during diplomatic efforts to avert war. During the resulting conflict, Lockjaw directly confronts threats to the Inhumans. He demonstrates fierce loyalty to the Royal Family, particularly Black Bolt, using his teleportation defensively and offensively to aid strategic repositioning in battles stemming from the Terrigen Mist crisis. He exhibits strong protective instincts towards Royal Family members and their allies, communicating primarily through barks, whines, and physical actions. His role extends beyond transportation, acting as a bridge between Inhuman society and human heroes amid the complex political and military tensions. Lockjaw's background reflects his traditional origins as a genetically altered canine companion and protector to the Royal Family, serving as their primary means of long-distance travel. His established powers and relationship with the Royal Family remain consistent, with the Terrigen Mist crisis presenting a significant challenge where his abilities are indispensable to managing the situation and protecting both Inhuman and human interests.
