Galactus is a cosmic entity which feeds by draining living planets of their energy.
When Galactus arrives to consume Earth, Iron Man ends up having to speak with him which results in both of them teleporting away. The Avengers track Iron Man to the planet where the D'bari live and witness their ships in the middle an evacuation after Iron Man who was empowered by the Power Cosmic led Galactus here. The Avengers had to work with the Guardians of the Galaxy to keep Galactus from consuming Earth. It later turns out that the planet that Galactus was consuming was becoming unstable before Galactus arrived. Galactus found himself unable to stop the process as the Power Cosmic-empowered Iron Man quotes "Galactus must feed." After the planet exploded, Galactus was knocked out cold, the D'bari settled on another planet, and Iron Man returned to normal. 
Galactus arrives on Earth where he lands on Las Vegas in order to consume Earth. After Terax was defeated, Galactus revoked his Power Cosmic and transformed She-Hulk into the Emerald Empress with it. The Agents of S.M.A.S.H. had to fight Galactus to keep him from consuming Earth. Following She-Hulk taking a dive in her fight against Terrax, Galactus returned the Power Cosmic to Terrax who takes Galactus to an uninhabited planet as part of the deal that She-Hulk made with Terrax.
