Summary
The longstanding debate regarding the smartest person in theMarvelUniverse was officially settled by the daughter ofGalactus.The Marvel Universe has many superintelligent characters, but fans have conflicting perspectives on who the smartest of them all truly is. There are the usualcandidates, including Iron Man, and Bruce Banner, and of course, the Fantastic Four’s Reed Richards – who Galacta declared the most intelligent.
InGalacta: Daughter of Galactus#1 – written by Adam Warren, with art by Hector Sevilla Lujan – the protagonist namesReed Richards (a.k.a. Mister Fantastic) as the smartest individual in the Marvel Universe. Given that she is endowed with a portion of the"Powers Cosmic" wielded by Galactus, the issue presents her acknowledgment of Reed’s intellect as more than just a statement of opinion, but as an observable fact of the Universe.

The way that Galacta’s powers work, her word on the subject can effectively considered gospel, meaning her assessment is as close to “canon” as a quantification of characters' intelligence can get.
As Reed Richards researches and explains what’s happening to Galacta, she’s utterly distracted by"the mind of the most brilliant hominid presently spawned by this world’s biomass."

Galactus isone of the most dangerous Marvel villainsand longest running enemies of the Fantastic Four.His daughter is Galactus' exact opposite. She isn’t as power hungry as he is and, as such, isn’t as hungry in general, restricting herself to a tight diet. As she leaves Galactus a"quantum-entanglement equivalent of a voicemail,“Galacta reflects on the Fantastic Four once she approaches them for help regarding a cosmic tapeworm inside her. As Reed Richards researches and explains what’s happening to Galacta, she’s utterly distracted by"the mind of the most brilliant hominid presently spawned by this world’s biomass.”
She salivates at the thought of how Reed’s electrochemical evokludge is oozing through his human brain, more than the average brain. Because of her unique insights on the universe intune to her biology,Galacta’s is able to see, smell, and taste realityin ways that no one else can. Her senses can practically taste the neurontransmitters firing off in Reed Richards brain as he’s talking,empirically establishing the extent of his superintelligence.This only makes her all the hungrier in his presence, thinking about how delicious the brain of Reed Richards (which amounts to 14 gigacalories) alone would be.

Cementing Reed Richards as Marvel’s smartest character, via Galactus' daughter, establishes the undeniable genius that he wields.

Galacta Puts An End To The Debate
The way that Galacta sees the universe makes it clear that the way she views Reed Richards is not a matter of opinion, but actual fact. In the same comic, she namesThor’s Mjolnir as Marvel’s ultimate weapon, not out of hyperbole, but because she can understand everyone and everything in all reality on a molecular level. That’s how she’s also able toconfirm thatReed Richards is literally the smartest man in the galaxy. Cementing Reed Richards asMarvel’ssmartest character, viaGalactus’daughter, establishes the undeniable genius that he wields, and his capability to outsmart any foe.
