The past history of Phillip Masters of Earth-772 mirrors that of his Earth-616 counterpart up until the point in which Spider-Man joined the Fantastic Four. Spider-Man's inclusion on the team would lead to Sue being put on the sidelines while the team traveled to the moon and battle Red Ghost and his Super-Apes.
Like his Earth-616 counterpart, Puppet Master would take control of the Sub-Mariner, only in this reality he would capitalize on the fact that Sue Storm was alone on Earth, using her torn emotions between Mr. Fantastic and Namor to lure her to meet the Sub-Mariner and be captured. Using the Sub-Mariner as his pawn, the Puppet Master would lure the rest of the Fantastic Five to battle Namor in Atlantis. In this reality, Namor would shake off the Puppet Master's control, and he would be defeated much in the same way on Earth-616: His submarine being crushed by a giant octopus originally used to guard Susan Storm while Namor battled her comrades.
The ultimate fate of the Puppet Master of Earth-772 remains unrevealed, however as his Earth-616 counterpart survived a similar fate it seems unlikely that his encounter with the octopus ended in his death.
