how strong is galactus

Galactus is an extremely powerful cosmic entity in the Marvel Universe, often considered one of the most powerful beings. His strength varies significantly depending on whether he has recently fed by consuming planets. When fully fed, Galactus can casually overpower many of the universe's strongest heroes, including Thor and the Fantastic Four, and can even destroy or easily defeat powerful cosmic beings like Celestials. He embodies a force of nature with abilities including vast super-strength, the "Power Cosmic" which allows reality manipulation, matter and energy control, telepathy, and immortality. Despite being nearly indestructible, he can be weakened when starved. Galactus stands above many cosmic characters but below some universal entities and can be a threat on a universal scale. In the Marvel Cinematic Universe (MCU), he is portrayed as similarly powerful, capable of planet destruction, super- strength, and cosmic powers, surpassing major villains like Thanos in direct combat when fully powered. However, his power is sustained by consumption and fluctuates with his feeding status.
