Wolverine was replaced by X-23 like just this year.
If Marvel bough Fox’s assets then I’d rather they keep the X-Men separate from the rest of the films and just continue the existing line. Really worried that the Dark Phoenix film is going to be utter wank though, the Scott and Jean they cast in Age of Apocalypse were both personality vacuums, and that film as a whole was a mess.
Bringing the FF into the Marvel Universe IS an exciting prospect. I’d definitely go in for a film set in the 60s where the FF are the OG superheroes to pop-up (after Captain America and other WWII guys tho, obv). Have it all campy and OTT with all the wacky Kirby shit they can throw in. But really the FF licence likely encompasses a shit ton of villians who’d work really well for the existing characters. Namor, Dr Doom, and the Skrulls would all be brilliant Avengers villains, and the cosmic stuff like Annilus would be good for a Guardians Of The Galaxy film, and then I’d shit my pants if we could see Thor scrapping with Galactus and Silver Surfer in a film.
