In the comics, yes. Not in film though. I don’t think they had any film crossovers before that.
There was no X-Men/Blade/Spider-Man mingling for example, but they were also from different studios (Fox, New Line, and Sony Pictures respectively).
Hasn’t happened yet, but that sort of thing is planned now that Disney has the Fox stuff. And they did get Spider-Man to fight Thanos despite originally being a Sony property.
So far the ultimate crossover has been in Deadpool and Wolverine. There you have the X-Men, Avengers, Fantastic Four (Johnny Storm at least) and Blade all in one film. They even brought in Elektra from those awful films. It took them a while to get the rights all squared away, but we get to benefit from Disney’s ridiculous power in order to cameo the crap out of a movie.
Yeah Kang Poochied back to his home planet because of the actor’s troubles. The What If Cartoon implied that the team from that show (The Exiles?) defeated him off camera.
I considered it, but that wasn’t the crossover of the Hulk/Thor/Daredevil TV or film series, because only Hulk had a series. They wanted to spin off something with Daredevil and/or Thor but it didn’t happen. It was a failed backdoor pilot.
I still remember for a long time thinking it was cool we actually got some kind of live action Daredevil and Thor, even if I had to wait until Netflix made a decent Daredevil, and we didn’t see a proper Thor (IMHO) until Hemsworth.
I remember way back when the writers could get a fanboy audience to Go Fucking Nuts by just having Val Kilmer ask: “Where will you go? The circus must be halfway to Metropolis by now…”
