I was just thinking, don't the legal rights for these characters differ between mediums? I mean, we all know Sony has the rights to Spider-Man films, so none of the MCU films can reference Spider-Man, and we won't see Andrew Garfield's Parker joining the Avengers, but this is TV, so is that different? I mean, doesn't Disney already have TV shows with all their characters, or is it different when it's animation? If they could get away with it, wouldn't it be great to have a small appearance by Spider-Man? Nothing to step on the toes of Sony's movies, but just an indication that he's out there, and he exists in this version of the Marvel universe. Same for the F4, and maybe even Mutants.
