@spambot: A starving Galactus swept an entire galaxy destroying every planet and star in it’s path in Annihilation after Annihilus siphoned all the energy he absorbed from the planets he was destroying with the cosmic control rod so him having the energy to “vomit the energy of a thousand worlds” means nothing. A starving Galactus still possess a great deal of energy unless he’s on the verge of death.
It doesn't really say he destroyed every planet and star in the galaxy. In the comic it actually happened in it just says it destroyed 3 star systems and was still going. Then in Thanos Imperative I think it was the writers mentioned it having swept the galaxy clean of the annihilation wave. That doesn't = destroying every star and planet in a galaxy. The batteries being used to siphon off Galactus' power were also in the same room so when they were destroyed its extremely likely he absorbed much of that energy before he unleashed that blast. Stop embellishing in an attempt to argue on behalf of Galan.
