This story discusses major plot developments, including the ending and post-credits scenes, in “The Fantastic Four: First Steps,” currently playing in theaters. From the very first scene, the question of what will become of the child of Reed Richards (Pedro Pascal) and Sue Storm (Vanessa Kirby) looms over “The Fantastic Four: First Steps.

First Steps' includes two post-credits scenes. Here's how that big reveal sets up what's coming in Phase 6 of the MCU.

Thanks to the Thunderbolts* post-credits scene, we'd all assumed we knew how The Fantastic Four: First Steps was going to end; with Marvel's First Family having hopped on a ship and travelling, somehow, to Earth-616 on the Sacred Timeline. You know, the universe in which the Avengers exist...

First Steps was just about reboots and retro vibes, think again. With their First Family, Marvel is cracking open a cosmic door to something far bigger.

When Entertainment Weekly asked Fantastic Four: First Steps director Matt Shakman if Downey Jr. filmed that post-credits scene, the filmmaker pleaded the fifth. "For others to talk about," he teased. However, Shakman did reveal that it was the Russo brothers who helmed the post-credits scene since it was shot for Avengers: Doomsday.

Yes, The Fantastic Four: First Steps stars Pedro Pascal — but it also transports the Marvel Cinematic Universe into a whole new phase.

When the movie wraps up and the credits roll, should you stick around a little longer for any post-credit scenes? Nope! There are no additional scenes after the story concludes, and Netflix will likely just throw you right into the original Happy Gilmore if you let it play out (but only until it leaves the platform at the end of the month).

Two bonus clips at the end of the blockbuster movie show that the DC universe might be different than you think.
