Avengers 4: 9 Surprise Cameos That Could Still Happen

9. The Defenders

Though the relationship between Marvel Studios and Marvel TV is... fractious, to say the least, that hasn't stopped fans from asking for the characters from the company's Netflix shows to appear alongside the Avengers.

Daredevil, Luke Cage, Jessica Jones and yes, even the other one, have all been a force on Earth's Mightiest Heroes at some point or another in the comics. Daredevil and Luke in particular can fondly recall their Avenging days, and with the synonymy between the Man Without Fear and Spider-Man being as strong as it is, it really doesn't make any sense to keep them apart.

More interesting, perhaps, is how the LEGO set for the Infinity War Sanctum Santorum contained a Daredevil Easter Egg, with ol' horn-head appearing on a Daily Bulletin newspaper on the sidewalk.

The Netflix characters were briefly considered for a brief appearance in the third Avengers, but with the logistics behind such a collaboration ostensibly proving too difficult to implicate, it might be a while before we see the Defenders collide with their big-league counterpart.
