Now that Marvel's Inhumans has debuted its first two episodes in IMAX theaters, audiences have been formally introduced to the Royal Family including the likes of Anson Mount's Black Bolt, Serinda Swan's Medusa and Iwan Rheon's Maximus the Mad. Many fans, however, are predicting that the series' true scene-stealer might just be Lockjaw, the property's giant dog with a penchant for teleportation and overall adorableness. One aspect behind the fan-favorite mutt that has had fans guessing, though, is how the show will handle Lockjaw's mysterious and controversial origins.

After debuting in the pages of Fantastic Four #45 (by Stan Lee, Jack Kirby and Joe Sinnott), it was made clear that the creative team saw Lockjaw merely as a giant dog. Years later, in the panels of The Thing #3 (by John Byrne, Ron Wilson and Hilary Barta), Lockjaw speaks in a quick scene that ostensibly revealed the teleporter as an Inhuman person who had ended up looking and acting like a giant dog after going through Terrigenesis, the process through which Inhumans have their biology changed (and typically develop super powers).

Thanks to an exclusive interview with Inhumans showrunner Scott Buck, we now know the answer as to what exactly Lockjaw will be in the upcoming television series. "Lockjaw is a dog," Buck told CBR. "Lockjaw is not an Inhuman. This is not his territory. He’s a dog. He’s always been a dog. How he came to be this way, why is he so big? How can he teleport? It’s a fun mystery. We’re not going to fully explore that — just yet, anyway."

The series' official synopsis states:

After the Royal Family of Inhumans is splintered by a military coup, they barely escape to Hawaii where their surprising interactions with the lush world and humanity around them may prove to not only save them, but Earth itself.
