Some flashbacks to the Fantastic Four origin story

Once again we’re back in 4:3, looking at what seems to be archive footage of the Fantastic Four’s foundational voyage into space. (The group’s origin story involves the four astronauts gaining their superhuman powers after exposure to cosmic rays during a mission in space.) While the MCU opted to skip Spider-Man’s origin story after bringing the character into the films a bit late, it looks like Marvel is going to explore the Fantastic Four’s beginnings to some extent in First Steps. We see shots of what looks like Sue’s invisibility manifesting for the first time on their spaceship, and the Thing watching old footage of himself before his skin was replaced with rocks.
