10 Things Marvel Wants You To Forget About The Fantastic Four
3. Their Comic Was Canceled Due To A Dispute With Fox
Comic publishers and movie studios are basically gigantic fussy babies masquerading as corporations, so it should come as no surprise that someone getting to play with Marvel's toys meant that Marvel would spend several years just pretending that they never liked that toy to begin with.
This is why no one likes Ike Perlmutter.
Due to a dispute with Fox over the film rights of Fantastic Four, Perlmutter sent down a kill order on anything having to do with the Fantastic Four, while the X-Men merely got severely sidelined. All this so that Marvel wouldn't have to give "free advertising" for what they saw as a rival getting to use their stuff.
Now obviously Marvel would get the last laugh there, and that's a whole other can of worms we won't get into today, but this is also clearly an example of Ike Perlmutter being just the worst.
The Fantastic Four have since come back, but there was a solid few years where the world the Richards family built outright rejected them, and whatever metaphors you draw from that... none of them are good.
