Lockjaw is Crystal's companion as well as the "family dog" and teleporter of the Inhuman Royal Family. When Maximus tried to seize the throne of Attilan, Lockjaw helped the rest of the Royal Family escape to Earth. Although he was hurt upon arriving on Earth, he helped the Royal Family to reunite before transporting them back to the Moon so they could try to save Attilan. After going through the process of Terrigenesis, Lockjaw was adopted by the Inhuman Royal Family where he served as their means for transportation, as well as their pet. Over the years of serving the family, Crystal, adopted him, taking full care of him, and the two became companions. With the new outbreak of Inhumans, Black Bolt sent down Triton to retrieve a new Inhuman. Lockjaw transported Triton down to Hawaii, but never returned to retrieve him, due to his possible demise down on Earth.
