Galactus' further MCU appearances after 2025's Fantastic Four film are unknown. However, he will likely be set up further in Avengers: Secret Wars before he becomes the main antagonist of the next three MCU phases: Phases 7, 8, and 9.
A version of the Beyonder is reported to be the villain of Avengers: Secret Wars in the MCU. While it seems that the MCU is setting Kang up to be the next big bad, it could also be the Beyonder. As per MyTimeToShineHello, a version of Beyonder will be involved in MCU's Secret Wars event.
As of this writing, Galactus is rumored to be the villain in the upcoming Fantastic Four movie. While some fans may think that Galactus is a threat that needs to be built up over multiple films, that might not entirely be the case.
Galactus, Marvel's Devourer of Worlds, is basically a god, but even he may not be able to defeat Imperiex, DC's Destroyer of Galaxies. Galactus is easily one of the most powerful beings in the Marvel Universe, but DC's equivalent, Imperiex, puts that power to shame.

Who is higher than Galactus?
Thanos (With Infinity Gauntlet)
With just the flick of a finger, Thanos could make Galactus disappear in an instant. With the might of all the Infinity Stones and his natural strength, Thanos is nearly unstoppable, and arguably no single hero or villain in the Marvel world could defeat him alone.
Despite the fact that Galactus is a cosmic being older than the universe who regularly consumes entire planets, the earthbound Juggernaut shockingly proves to be more powerful than him–and one stunning side-by-side comparison confirms it.
Galactus proved more than a match for Darkseid - who had ample opportunity to utilize his greatest powers and even try to turn the Silver Surfer to his will - and the Devourer of Worlds only spared his foe once it became clear that he had nothing to gain by continuing their conflict.
Galactus would easily defeat Dormammu outside the Dark Dimension, but it turns out that even on Dormammu's turf, he retains his power and has the means to grow even stronger.
Galactus was killed by Thor during the "Herald of Thunder" story arc in Thor (vol. 6) #1–6 (March–August 2020), and reappeared after a two-year hiatus in Fantastic Four (vol. 6) #45 (July 2022)—the final issue of the event "Reckoning War"—where Galactus is resurrected by his former heralds.
Robert Downey Jr. confirmed that Iron Man 4 is indeed in the works. While negotiations continue for his return, this would mark his 7th appearance in a standalone Marvel movie and his 9th outing as Tony Stark in total.
Yes, reports suggest that Robert Downey Jr. is expected to return as Tony Stark/Iron Man in Avengers: Secret Wars. While the original Tony Stark of Earth-616/199999 sacrificed himself, Marvel could use the Multiverse to bring RDJ back as a variant Tony Stark.
The Fantastic Four had the privilege of being the first superhero team to take on and defeat Kang the Conqueror. After Kang traveled through time and conquered Ancient Egypt, the Fantastic Four found themselves also traveling through time and battled Rama-Tut, ousting him from his throne.
Doctor Doom is the main antagonist in 2015's Secret Wars comic, which gives the idea some appeal. The first Secret Wars miniseries from 1984 is being overlooked, despite Doom dispatching Kang in its story.
The heroes include the Avengers (Captain America, Captain Marvel, Hawkeye, Iron Man, the She-Hulk, Thor, the Wasp, and the Hulk), three members of the Fantastic Four (Human Torch, Mister Fantastic and the Thing), solo heroes (Spider-Man and Spider-Woman) and the mutant team the X-Men (Colossus, Cyclops, Nightcrawler, ...
Galactus may have immense power, but he needs to constantly feed on planetary-levels of energy to sustain it. Goku, on the other hand, often reaches his most powerful form when he's at the very end of his rope. So while Galactus would get weaker as the fight went on, Goku would get stronger, giving him the edge.
In the pure context of who is stronger, galactus would win. He's a world devouring abstract conceptual deity. But Kang has his merits such as his title and if marvel likes anything it's making their titles literal. Hulk is physically superior to EVERYONE no contest.
The rule of Cyttorak's magic states that nothing in the universe can physically stop his avatar, which is why the full-blast of Thor's God-Force just slid right off the Juggernaut while Galactus (a being not protected by magic) takes damage from it.
Oddly enough, Hulk might actually be able to hit Galactus hard enough that he notices that he's been hit. But that's about as far as the fight goes. Galactus would see him as nothing more than a little green annoyance to be flicked away like a gnat.
In terms of sheer power, Galactus would be able to do the most destruction, followed by the Death Star and then Unicron, going by the size of planets that they have attempted to destroy in the past.
Against Galactus, a being of Superman's size and strength would only stand a chance if Galactus is tremendously weak with hunger. Even if that were the case, the odds of Superman triumphing over Galactus are incredibly slim.
There was one time in the comics when Deadpool faced Galactus head on, and somehow won. Instead of slicing the giant to pieces or punching through his heart, Deadpool just talked and talked - and talked. Indeed, Galactus got so annoyed by Deadpool's quips that he eventually surrendered.
The source of the Power Cosmic and among the most powerful cosmic entities in the Marvel Universe, Galactus destroys worlds with little effort. Spider-Man stands no chance against him but in at least one reality in the multiverse, Earth-11638, Spider-Man single-handedly defeated Galactus with some supernatural power.
While the original Silver Surfer of Marvel's Earth-616 universe is immensely powerful on a cosmic scale, he is nothing compared to his DC crossover variant, as that version could take down Galactus with a single hit–and there's one very specific reason as to how that's even possible.
