Galactus possesses no true form, but this nightmarishly horrific spin on the Devourer of Worlds transforms him into the monster he truly is.

Reed’s plan for victory against Galactus, as heartbreaking as it seems, is a stroke of genius on his part. Galactus consumes planets to stay alive as he traverses the cosmos of the Marvel Universe, so depriving him of that nourishment would cause him to wither to nothing. Furthermore, Reed knows there’s no real way to keep Galactus away from planets without controlling him from within. By taking control of Galactus,Reed Richards gets the perfect opportunity to starve Galactus to death.Instead of physically taking planets away from Galactus' reach, the Fantastic Four discover a proper solution at last.

Comic book panel: Reed Richards reveals that, because Galactus is now under his direction, he is choosing not to devour planets and will instead let himself starve to “end the threat of Galactus forever."

Originally, there was only one weapon strong enough to defeat Galactus in Marvel lore: theUltimate Nullifier. This weapon is such a powerful weakness for Galactus that the mere sight of it causes him to concede to the Fantastic Four and leave Earth in peace inFantastic Four#50. Since then,Galactus has been beatenin other ways throughout his history by a variety of different Marvel heroes, buthe’s always and eventually returned. One Fantastic Four hero has used similar methods as Reed Richards to defeat him for a period of time, using Galactus' signature Power Cosmic against him.

With the Power Cosmic, the Human Torch Reaches Galactus' Level

While Reed’s strategy to reach Galactus' level proves effective, he isn’t the first to be granted the Power Cosmic and use it to overcome the tyrant. In theRising Stormstoryline by Waid and Mike Wieringo,the Human Torch gets kidnapped by Galactusandbecomes his powerful new Herald. Because Johnny had swapped powers with Invisible Woman beforehand, the Power Cosmic is channeled through him as an upgrade to her power-set rather than his usual fiery abilities. Johnny takesInvisible Woman’s powersto the next level with “cosmic sight,” which is what allows him to beat Galactus.

Johnny manages to use a machne built by Reed to move Galan’s energy around, freeing him from the soul of Galactus. Though this defeat isn’t permanent, asGalactus has since come back more terrifying than ever, it shows howthe Fantastic Four tapping into the Power Cosmic enables them to surpass Galactus.

Reed Richards is indeedcapable of killing Galactusonce he’s stolen his form and powers. However, in the end, his Fantastic Four teammates stop him from going through with his plan. He takes on the Power Cosmic because he feels that he’s lost his intellect after the birth ofhis daughter, Valeria, hence why he’s risking his life for a taste of Galactus' vast intelligence. His family assures him that he’s just dealing with the stress of a new child, and that he shouldn’t leave his children behind with his sacrifice. Thus,Reed relinquishes Galactus' power and returns to his loved ones.
