This story contains spoilers for “The Fantastic Four: First Steps.”
Marvel’s First Family has finally made its formal MCU debut, which means it’s time to engage in everyone’s favorite tradition: breaking down the movie’s post-credits teases to suss out what’s next.
Directed by “WandaVision” helmer Matt Shakman, “The Fantastic Four: First Steps” introduces audiences to Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Ben Grimm (Ebon Moss-Bachrach) and Johnny Storm (Joseph Quinn). The movie, which officially opens Friday, pits the quartet of superpowered astronauts against Galactus (Ralph Ineson), a cosmic entity with an insatiable hunger for planets.
As the title teases, “First Steps” marks the beginning of Phase 6 of the Marvel Cinematic Universe, which will culminate with a pair of massive “Avengers” crossover films.
Like most MCU installments, “The Fantastic Four: First Steps” features multiple post-credits stingers. The first, which is shown midway through the end credits, sets up the superhero team’s next big adventure.
The mid-credits scene takes place four years after the Fantastic Four’s showdown with Galactus. It shows Sue sitting on a couch, reading a story to her and Reed’s son, Franklin Richards. After finishing the book, she steps away to grab another, turning down robo-assistant H.E.R.B.I.E.’s suggested title. Sensing something is wrong, Sue starts charging her powers. She rounds the corner to check on Franklin and finds a mysterious cloaked figure interacting with her child.
While his face is not shown, his green cloak and the mask he is holding make it clear to fans familiar with their Marvel lore that this is Doctor Doom.
This marks the first appearance of the iconic villain in the MCU. The character, also known as Victor von Doom, made his comic book debut in “Fantastic Four” No. 5 (1962) and has been a foe of Marvel’s First Family ever since. In the comics, the character is both a scientific genius and a sorcerer hailing from the fictional country of Latveria. (The name of the country is briefly shown in “Fantastic Four: First Steps.”)
Doom’s introduction into the MCU has been highly anticipated since Marvel Studios’ presentation last year at San Diego Comic-Con. Among the major announcements was that the fifth “Avengers” film had been retitled “Avengers: Doomsday” and that “Iron Man” actor Robert Downey Jr. would be returning to the franchise as Doctor Doom.
While Doom’s exact interest in Franklin is not revealed, it’s easy to assume that the child’s powers would be appealing to a supervillain. This encounter also hints at the reason why the Fantastic Four eventually make their way to the universe where the rest of the MCU heroes reside.
“First Steps” is set on Earth-828 — a tribute to “Fantastic Four” co-creator Jack Kirby, who was born Aug. 28, 1917 — a retrofuturistic world in a separate corner of the Marvel multiverse. But the “Thunderbolts*” post-credits scene shows the Fantastic Four’s spacecraft Excelsior appearing in their world on Earth-616. Could Doom have kidnapped young Franklin and taken him to an alternate universe? Whatever the reason, Samuel Sterns’ warning from the “Captain America: Brave New World” post-credits scene was apt: The multiverse is coming.
Fans might wonder how the “Fantastic Four” post-credits scene might have played out had the studio not altered its original plans to feature Kang the Conqueror as the franchise’s next big bad. In the comics Kang and Franklin are part of the same family tree so it’s easy to imagine him as the surprise interloper Sue sees. Either way, a magical nanny might have been helpful. (Marvel Studios pivoted from its original plan after Kang actor Jonathan Majors was convicted on assault and harassment charges in 2023.)
The second “Fantastic Four: First Steps” credits scene is shown after the full credits roll and serves more as a fun bonus and tribute to the eponymous superhero team’s animated past.
“Avengers: Doomsday,” hitting theaters Dec. 18, 2026, will be a massive MCU crossover featuring members of the Fantastic Four, the Thunderbolts/New Avengers and more. Confirmed “Doomsday” cast members include veteran “Avengers” stars Chris Hemsworth (Thor), Anthony Mackie (Sam Wilson/Captain America), Sebastian Stan (Bucky Barnes), Paul Rudd (Scott Lang/Ant-Man) and Tom Hiddleston (Loki), as well as Florence Pugh (Yelena Belova), David Harbour (Alexei Shostakov/Red Guardian), Lewis Pullman (Bob Reynolds), Wyatt Russell (John Walker) and Hannah John-Kamen (Ava Starr/Ghost).
Up next for the MCU is “Wonder Man,” a series starring Yahya Abdul-Mateen II that will debut on Disney+ in December. The next Phase 6 film is Marvel and Sony’s “Spider-Man: Brand New Day,” slated for a July 2026 release.
