Note: This post contains spoilers for Marvel’s The Fantastic Four: First Steps.
New plot details for The Fantastic Four: First Steps have been leaked online by a subreddit called “Leaks and Rumors.” In a recent interview, Marvel President Kevin Feige confirmed that the events of The Fantastic Four: First Steps will lead directly into Avengers: Doomsday. It seems the new plot leak has a confirmed connection.
The film opens with the line, “You all know the story.” We get a brief montage of past battles — including the Fantastic Four fighting Mole Man — and an action sequence with them battling Red Ghost and his chimps. Back home, Sue (Vanessa Kirby) discovers she’s pregnant.

As the team prepares for the baby’s arrival, Shalla-Bal arrives with a warning. The team decides to go into space with her — she takes them to Galactus (Ralph Ineson), who is on a massive ship consuming a planet. Galactus agrees to spare Earth — but only in exchange for their child. The team refuses — and battles the Silver Surfer (Julia Garner).
During the fight, Shalla-Bal is thrown into a wormhole — where only a minute passes for the team, but she experiences a whole month. While she is gone, Reed (Pedro Pascal) comes up with a plan to teleport Earth away from Galactus — but when Shalla-Bal returns, she sabotages the teleportation technology. The team then changes course — now planning to teleport Galactus himself away from Earth.

Sue Storm (Invisible Woman) — the team’s leader — sacrifices herself to defeat Galactus, using all her powers to send him through a portal. She is later resurrected by her son — Franklin Richards.
Post-Credits Scene:
Sue is reading a book to Franklin. She gets up to grab another one. In the background, we hear the sound of a teleportation device activating. When she returns — she freezes. The book slips from her hand. Standing before her is a cloaked figure — Doctor Doom. We don’t see his face — but his full body is visible beneath a silver cloak. In one hand, he holds his iconic mask (rendered in CGI) — in the other, he carries an unconscious Franklin.
Cut to black. “The Fantastic Four will return in Avengers: Doomsday.”
Here’s the plot details for The Fantastic Four: First Steps:
Marvel Studios’ The Fantastic Four: First Steps introduces Reed Richards / Mister Fantastic (Pascal), Sue Storm / Invisible Woman (Kirby), Johnny Storm / Human Torch (Joseph Quinn), and Ben Grimm / The Thing (Ebon Moss-Bachrach) as they face their most daunting challenge yet. Forced to balance their roles as heroes with the strength of their family bond, they must defend Earth from a ravenous space god called Galactus (Ineson) and his enigmatic Herald, Silver Surfer (Garner). And if Galactus’ plan to devour the entire planet — and everyone on it — weren’t bad enough, it suddenly gets very personal.
The film also stars Paul Walter Hauser, John Malkovich, Natasha Lyonne, and Sarah Niles. Directed by Shakman, produced by Kevin Feige, and executive produced by Louis D’Esposito, Grant Curtis, and Tim Lewis.
The Fantastic Four: First Steps hits theaters and IMAX on July 25, 2025.
