History
Galactus's body was originally destroyed by Jean Grey during her time in space. But this caused him to be transformed into a psionic entity driven by the pure rage of what had happened to him. He ventured to Earth with his heralds the Silver Surfers to exact revenge on Galactus's murderer Jean.
He planned on destroying the planet but Jean who was possessed by the Phoenix Force used her enhanced abilities to kill the remaining part of the World Devourer and his heralds.[1]
