@JDMarvel and we can introduce more characters, obviously, but I think the fantastic four and the x-men are already enough. But we still might not want to see the x-men clash with the new avengers right off the back whereas I think it would be cool to see the F4 clash with the guardians right away. I don't think they would like each other right away so that could be some good comic relief. I feel like Johnny Storm and Peter QUill would vibe....
But we don't even have to introduce all of the x-men right away? Start with one fo them meeting the entiry of the new avengers because the avengers try and save the world from what thtey think is some evil person but is actualy just a rouge mutant? Something like that. I haven't come up with good plots for the actual seperate movies tho
