Which is why I said the spun off a bunch of characters( and brought Namor back to prominence) but didn’t retain enough that have a certain dynamic with them.The only reason you can say that is because a lot of their villains have been made into "everybody's" villains.
Kang is literally a descendant of Reed.
Annihilus was made to be more of an Avengers villain but he started in FF.
Super Skrull and the Kree/Skrulls in general are considered "cosmic Marvel villains" but started in FF.
Klaw became a BP villain but started in FF.
MODOK was originally a FF villain.
Mephisto was a FF villain
So on and so forth. They still have a ton of other villains that haven't made it out of comic book form that you can build up tho.
Xmen doesn’t have deep bench either but there are so many that they have dynamics within dynamics.
