Fantastic Four’s Shocking Credits Scene Sparks Epic Avengers: Doomsday Multiverse Rumors

The Fantastic Four: First Steps mid-credits scenes have ignited a wildfire of rumors surrounding Avengers: Doomsday, and fans are buzzing with excitement and speculation. What exactly do these post-credit moments mean for the Marvel Cinematic Universe’s future? Let’s break down the key points and what they could imply for the upcoming Avengers installment.
- Introduction of Doctor Doom in a mysterious mid-credits scene
- Potential multiverse connections between Fantastic Four and Avengers: Doomsday
- Robert Downey Jr.’s rumored involvement as Doom
- Implications for Franklin Richards and the cosmic stakes ahead
- How these scenes tie into Marvel’s broader Phase 5 and 6 plans
Doctor Doom’s Shadow Lurks in the Mid-Credits Scene
Right after the main story, a mid-credits scene drops a bombshell: Doctor Doom appears, crouched in front of a young Franklin Richards, mask in hand, cloaked in his iconic green cape and hood. This moment is set four years after the events of First Steps, but Marvel hasn’t confirmed if this Doom is played by Robert Downey Jr., who is rumored to star in Avengers: Doomsday slated for 2026.
Interestingly, the scene resembles an AI-generated fan video that surfaced just days before the movie’s release — a coincidence that has fans questioning how much of the rumor mill is becoming reality.
What’s clear is that Doom knows Franklin is no ordinary child. Much like Galactus, who also coveted the baby, Doom’s interest hints at Franklin’s immense cosmic potential. The scene shows Doom sneaking into the Baxter Building apartment — a chilling moment that raises the question: Is this Doom from the Fantastic Four’s home universe Earth-828, or is he a multiverse traveler?
Multiverse Mysteries and Marvel’s Expanding Universe
The Fantastic Four’s adventures unfold in Earth-828, a different universe from the main MCU setting, Earth-616. While Latveria, Doom’s traditional home, is acknowledged in First Steps, Doom’s threat level on this Earth seems low, as he isn’t listed alongside other villains like Red Ghost or Puppet Master. This suggests the Doom we see might be from another universe altogether, possibly stepping through a TVA-like portal to hunt Franklin for his cosmic power.
This theory gains weight when considering the larger Marvel plans. Avengers: Doomsday is rumored to explore multiversal chaos, with Doom aiming to become a godlike figure by merging realities — an arc inspired by Jonathan Hickman’s acclaimed comics run culminating in Secret Wars.
What We Know About Avengers: Doomsday
Here’s what’s officially on the table:
- Directors Joe and Anthony Russo return, having helmed Avengers: Endgame.
- The movie is set to release on December 16, 2026.
- Robert Downey Jr. is confirmed to lead a star-studded cast including Fantastic Four, Thunderbolts, past Avengers, and even some 20th Century Fox-era X-Men characters.
On set photos have shown Ebon Moss-Bachrach’s Thing alongside Wyatt Russell’s U.S. Agent, hinting at a massive team-up. But the biggest tease remains Doom’s pursuit of Franklin and the potential multiverse collapse that could set the stage for the much-anticipated Secret Wars event in 2027.
Could Doom Be a Variant of Tony Stark?
One wild speculation is that this Doom could be a variant of Tony Stark. While nothing is confirmed, Marvel’s creative team, including Kevin Feige and director Matt Shakman, are keeping details tightly under wraps, promising only that more will be revealed over time.
The Post-Credits Scene: A Fun Twist
After all the intensity, the post-credits scene offers a lighter moment: an intro to a fake Fantastic Four cartoon created by Titmouse, a studio known for modern 2D animation. This segment pays homage to the classic 1994 Fantastic Four cartoon but with a fresh and much better style — a nice treat for fans craving a bit of nostalgia with a modern twist.
All in all, the credits scenes from Fantastic Four: First Steps have set Marvel fans abuzz with theories and excitement. With Avengers: Doomsday on the horizon, the MCU’s multiverse saga is shaping up to be one of its most ambitious yet. Stay tuned as more details emerge!
