Whether you grew up watching Spider-Man: The Animated Series between 1994 and 1998 or have since tracked it down (you can find it on Disney+), we're sure you're somewhat familiar with this show.
If so, you'll probably remember that it ended on a major cliffhanger when Spider-Man defeated the Green Goblin and Mary Jane ended up being trapped in limbo. We never got to learn what became of MJ, meaning this was yet another series focused on the web-slinger that had an unresolved ending.
A sixth season didn't happen after executive producer Avi Arad and the head of Fox Kids, Margaret Loesch, reportedly got into an argument that ended with the series being cancelled. Over the years, producer John Semper Jr. has shared some intel on plans for the show's continuation, and that's what we've rounded up here.

6. Spider-Man Finds Mary Jane
While there was a certain level of satisfaction that could be taken from the final episode of Spider-Man, Mary Jane's fate being left a mystery has bugged fans for years now.
The series wouldn't have kept us waiting, though, because season six was going to kick off with Madame Web taking the wall-crawler to 19th century London. He'd have found MJ there, albeit without her memories, and was ultimately successful in bringing her home.
However, this trip through time wouldn't have been without its challenges as Peter was set to learn that Carnage was also there, and the real Jack the Ripper!
This would have been a solid resolution to that cliffhanger, but there were plenty of other crazy ideas set to follow previous seasons adapting everything from Secret Wars to The Clone Saga.
5. More Dormammu
Dormammu became a recurring threat in Spider-Man and surprisingly even played a key role in the creation of Carnage. It probably won't shock you to learn that he was set to return in the sixth season, this time teaming up with Mysterio.
That villain was going to be revealed as being alive and in possession of the Time Dilation Accelerator.
Initially using it to rob banks, Quentin Beck would have inadvertently found himself in Dormammu's dimension. From there, he'd have teamed up with this powerful new ally, taking Baron Mordo's place by setting out to bring the Doctor Strange villain into Spider-Man's world.
Ultimately, Ghost Rider would have made a guest appearance to help Spidey defeat them both.
4. Betty Brant's Debut
The series made good use of Peter Parker's supporting cast, but if there was one character conspicuous by her absence in The Daily Bugle, it was Betty Brant.
Well, she was coming to Spider-Man, albeit as Joe "Robbie" Robertson's assistant rather than J. Jonah Jameson's secretary. Just like her comic book counterpart, she was going to have a crush on Peter, though it's unclear what sort of impact - if any - that was going to have on his relationship with Mary Jane.
Interestingly, this Betty's surname would have been spelt "Brandt," though it's possible that was just a mistake on the concept art that's since done the rounds.
There's no word on who would have voiced Betty in the series.
3. New And Returning Villains
If there's one thing Spider-Man always did right, it's pitting the web-slinger against a varied set of villains.
More new additions were set to be made to the series in its sixth season, including Beetle, Puma, and Jack O'Lantern. Seeing that trio in action would have been a blast; sure, they're not exactly among Spidey's most iconic villains, but the show could have had a lot of fun with them.
Most exciting, however, were tentative plans for Sandman to appear.
Some familiar faces were also set to return, with Miles Warren once again suiting up as the Jackal and Richard Fisk returning, this time as the Rose (in a storyline that was also set to involve him framing Ned Leeds).
2. Spider-Man And His Amazing Friends
We always got to see a lot of amazing Easter Eggs in Spider-Man, but one big plan for season six would have featured a throwback to Spider-Man and His Amazing Friends.
In an episode guest-starring Iceman and Firestar (likely voiced by original actors Frank Welker and Kathy Garver), Spidey was going to team up with them to beat an unknown villain.
However, once that team-up had concluded, they'd have all looked at each other and said something along the lines of, "Hey, maybe we should all hang out together and be friends. Wouldn't that be amazing?" After a brief pause, they'd have said "Nah" and gone on their separate ways!
This would have been one for longtime fans, and it's a real shame this never became a reality.
1. The Green Goblin Lives
While it took a while before he was introduced, the Green Goblin definitely became Spider-Man's greatest enemy in this show, though it looked like his story might have been over after Norman Osborn ended up trapped in limbo.
Just like Mary Jane, however, he was set to escape from that purgatory and would have taken the mantle of Green Goblin back from his son, Harry.
We don't know how things would have played out for him beyond that, but this rematch would have been a must given everything he'd put Peter through. There were lots of comics featuring Norman from around this time that could have inspired what we'd seen in the series too.
Oh, and while we're on the subject of "green," rumour has it The Hulk was set to appear!
