The 1994 cartoon:
- The Other Darrin: A coupleómost notably, Doctor Doom and the Human Torchóbut nowhere near as extreme as what Iron Man went through.
- What Could Have Been: Plans for a third season included Sue's pregnancy (with She-Hulk or Medusa filling up the vacancy) and the return of the Sub-Mariner.
- And probably we've seen the return of Puppet Master, and find out where he's been.
The comic book:
- Follow the Leader: By Stan Lee's own account, the Fantastic Four were conceived as a way to cash in on the success of DC's Justice League of America series.
- What Could Have Been: According to Stan Lee's initial◊ plot◊, published in Fantastic Four #358:
- Reed's stretching powers would've harmed him.
- Sue was originally permanently invisible, and she'd be more or less an Invisible Streaker. To compensate, Sue would wear a mask to indicate her location.
- Ben would suffer from Chronic Back Stabbing Disorder.
- Johnny's powers were limited, meaning at any point his flame could shut off.
- During Chris Claremont's run on the title, he had initially planned for Kitty Pryde to be a recurring cast member, serving as a live-in nanny for Franklin Richards (this took place shortly after Excalibur was cancelled). Then-editor of the X-Men franchise Bob Harras wanted Kitty back in the main X-Men team.
- Writer Revolt: At least one version recounting the team's creation explained that it was meant to be Stan Lee's final comic work, filled to the brim with Author Appeal as a way to get back at Martin Goodman for pressuring Lee to Follow the Leader and write stories based on whatever genre was popular at the time. If the book had been a failure like Lee anticipated, he would've readily retired from comic book writing to pursue writing for Hollywood.
