9 Major Marvel Movie Events That Could Follow Avengers: Infinity War
5. Secret Invasion
There are a lot of Secrets at Marvel, and Invasion is one they should consider sharing with cinemagoers.
A loose adaptation is the way to go since Marvel doesn't hold the rights to every character involved in this 2008 event but, thematically, it's good fit for the MCU.
As the Chitauri found out the hard way in the original Avengers, Independence Day-style invasions don't go down too well in the Marvel Cinematic Universe due to the number of super-powered beings on Earth.
So wannabe alien infiltrators must be more creative than that, like the Skrulls were in Secret Invasion. It turned out the shape extraterrestrial race had been abducting and swapping out the planet's heroes for years, so nobody knows who to trust.
This scenario would work well in the MCU as it would pit the Avengers and their allies against an alien threat that has learned lessons from the past, thus forcing Cap, Iron Man and co - presuming they're still around by this point - to alter their tactics.
Of course, Marvel's top brass would need to get their counterparts at 20th Century Fox around the debating table to work out who own the rights to what where the Skrulls are concerned, but it could happen.
