History
The history of this Invisible Girl presumably mirrors that of her Earth-616 counterpart up to the point when Galactus first arrived on Earth. Unlike on Earth-616, the Watcher chose not to interfere so the Fantastic Four battled Galactus alone. Once Galactus had assembled his Elemental Converter, Sue tried to stop him by using her invisible forcefields to keep the device's twin igniters from touching. However, when Galactus realized that she was responsible, he ended her interference by blinding her. Mister Fantastic eventually stopped Galactus by using his own technology to create an Ultimate Nullification Ray that projected zero energy that was poisonous to Galactus and using the weapon to kill Galactus. Mister Fantastic then used the zero energy to undo the harm that Galactus had caused to the planet and, within a year, turn Earth into a paradise.[1]
Unfortunately, this miracle proved to be short-lived because the generator that Richards had built began to malfunction. Reed realized that the Zero Energy was building up too fast but by then it was too late for anything to be done. The Zero Energy exploded out of its containment and destroyed New York City. Then, with nothing to stop it, the Zero Energy continued unchecked and destroyed the Earth before spreading out across the entire universe, unmaking it all.[2]
