Galactus "died" during a battle with the entire Shi'ar empire, multiple other races and most of Earth's superheroes. This was only after he was severly weakened from hunger and the Silver Surfer turned Galactus' own energy siphoning equipment against him. Galactus turned into pure energy upon his death. However, when he died, a creature named Abarax (Sp?) moved in from some alternate reality with the power to destroy the universe. Mr Fantastic's Kids, somehow brought Galactus back to form to kick Abarax's ass which he promptly did. He then kicked 9 colors of sh1t out of Mr T., Chuck Norris, and Vin Diesel.
