10 Greatest MCU End Credits Scenes
4. The Avengers
Whereas the other movies had been slowly building towards something big, Avengers was the first proof of concept that these heroes coming together was actually going to work. Then again, the real threats were just beginning.
Throughout the film, most of us fans were just under the impression that Loki had been working with the Chitauri Army to rule Earth, but there was still some thread that seemed to be missing. With Tony Stark launching a nuclear missile into the vacuum of space, he had caught a glimpse of what other terrors were out there in the universe. Even though there is a delightful scene of shawarma indulgence towards the end, this is where many of us first caught a glimpse of Thanos.
As a mystic figure talks about the Avengers' victory, we see an off-color purple alien come into frame - the Mad Titan himself, Thanos.
Despite having one of the biggest victory laps in the entire MCU, this last scene showed everyone that now was not the time to rest. Things were about to get a lot bigger than we imagined.
