The marvel cinematic universe is again welcoming home the Fantastic Four. They’re rebooting the four and opening up the MCU to one of the best superhero teams plus some of the best villains like Doctor Doom, Galactus, Silver Surfer, and Annihilus. Marvel head Kevin Feige has only given us limited details about his reboot plan saying at Comic-Con, “I’m extremely excited about those characters and about bringing Marvel’s first family up to the platform and a level that they deserve” If you’ve been watching the MCU films closely there have actually been a number of clues and details that could set up the Fantastic Four’s MCU homecoming. There are four theories for how Marvel has already opened this door without fans realizing it.
#1 Avengers Tower will become the Fantastic Four’s Baxter building
We saw in spider-man far from home that the former Avengers tower was going through some remodeling. Some have suggested it could be the new Oscorp building but another theory is that the new occupants are Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm. In the comics the Baxter building was the towering Manhattan headquarters for the Fantastic Four it was renovated so that the team could use the top five floors for all their hero needs. In the MCU the vacated Avengers Tower is perfect. This place comes with a hi-tech lab, a jet landing pad and the guy who loved to be Iron Man.
#2 The Fantastic Four heroes are from another universe
Avengers End Game crack the MCU egg wide open with a series of alternate branch realities; one in which Loki gets away, another in which cap goes back in time to marry Peggy. Despite Mysterio’s lies in far from home, the MCU multiverse is still very real and we’ll continue to explore in Doctor Strange in the multiverse of madness. We don’t really know the rules of interdimensional travel in the MCU but you know who probably does Reed Richards. What if the Fantastic Four are superheroes from another alternate history but unlike Mysterio, their backstory is actually legit. Perhaps, during Doctor Strange and Wanda Maximoff multiverse exploration in that film. They’ll arrive in a branch reality in which is fantastic four are not the Avengers, the team protecting earth That would be super cool essentially it would be a reality in which Marvel didn’t sell off its most popular characters to other movie studios. You know the good timeline but of course, bringing in the good guys from that alternate timeline would also probably open the door to the dr. Victor Von Doom. What if Dr. Doom is the villain of Doctor Strange in the multiverse of madness.
#3 The Fantastic Four have been in the MCU the whole time in the quantum realm
One of the biggest loose threads from Marvel phase three was how Janet Van Dyne survived on her own for so long in the quantum realm. She didn’t say much but as she and Hank Pym left the quantum realm you can barely make out what looks like a tiny city in the background which is really cute. The quantum realm is an adaptation of the micro world in the Marvel Comics, a place visited by Ant-man and the Fantastic Four and Dr. Doom shrunk down into nothing but later was discovered as the ruler of the subatomic world. Perhaps part of Janet’s mystery story was connected to Doom or the Fantastic Four in that quantum realm city, racing on those goofy maggot things of course and game revealed that the quantum realm contains time vortexes and enable time travel. Scott Lang went into one of those so the five hours that he spent in the quantum realm was actually five years up here. This could connect with ant-man director Peyton Reed’s old Fantastic Four movie idea in 2003 which would have set the Fantastic Four in the 60s. What, if there were all collaborators with Hank Pym in the 60s, got lost in the quantum realm slipped into a time vortex and popped back out in the 21st-century post Endgame. Now everyone’s a superhero it’s not just us with. The quantum realm could be their version of the negative zone.
#4 In Space During Thanos Snap.
The way the Fantastic Four have got their powers of course in the comics is through cosmic radiation while on an unpermitted space flight. Endgame notices the way rocket described Thanos snap; “when Thanos snapped his fingers earth became ground zero for a power surge of ridiculously cosmic proportions no one’s ever seen anything like it”. Rocket then said that another surge happened again that was when Thanos used the stones to destroy the stones reducing them to atoms. I’m curious what effect that second shockwave could have had across the entire universe like a rift into the negative zone or enhancing the powers of the Fantastic Four turning one of them into a rock.
