Occulus was the ruler of the Inniverse, who was trained by the Gem Guild of that world and learned to tap the vast powers of the sky-bound gems of that dimension. He eventually rose to lead the guild and his world, plucking out one of his eyes and replacing it with a gem in his quest for power. His troops kidnapped Franklin Richards when a portal to their dimension was opened by the Fantastic Four, and learned the child could amplify his powers. He was opposed by the FF. Despite gaining vast power due to Franklin, he was ultimately defeated when Reed Richards had the resistance build a giant gem screen; the screen's oppositional charge deflected Occulus into deep space. Occulus was later rescued by the rogue Watcher Aron, who used him to battle the FF and Fantastic Force alongside other villains; he was defeated once again.
