Avengers 4 trailer should better be out of this world (no pun intended) given the hype it has created all over the social media platforms. The Untitled Avengers 4 is the sequel to Avengers: Infinity War and fans are eagerly waiting to see the very first trailer of the movie. Apart from the whole feature-length film, fans are also excited to see what Marvel and directors Russo Brothers are planning to show in the mid-credit and end-credit scenes in Avengers 4.

Mid-credit and post-credit scenes are some sort of a tradition in Marvel movies. The mid and post-credit scenes somehow tease the audience about the next movie in the series. There are few best post-credit scenes in Marvel films like, in 2008 release Iron Man, during the post-credit scene, it was shown how S.H.I.E.L.D.'s director Nicky Fury meets Tony Stark to inform him of a new initiative: The Avengers; In 2011 Thor, it was shown how Nick Fury brings Dr. Erik Selvig into S.H.I.E.L.D.'s secret underground facility to show him an artifact (which later turns out to be an Infinity Stone), and how it is actually Loki, who is controlling Dr. Selvig.

Even in Avengers: Infinity War, after the heartbreaking climax, fans were eager to see what's in store for them during the post-credit scenes. Infinity War's post-credit scenes revealed how before going into dust, Nick Fury manages to send an SOS to Captain Marvel.

It is not wrong to say that upcoming Avengers 4 will be the biggest Marvel Cinematic Universe film to date. The film is surely not going to be the last film from the studio and fans are excited to see if, during the post-credits of Avengers 4, they will get to see some new characters or a way ahead.

As per several speculations, Avengers 4 will reportedly introduce The Eternals. As per a few tweets by a Marvel expert, the studio is already casting for two Eternals characters, Karen and Piper, which will reportedly feature in Avengers 4 mid or post-credit scenes.

The most anticipated superhero film is scheduled to release one month after the release of Captain Marvel. The upcoming Avengers 4 will conclude the first phase of Marvel Cinematic Universe that began with Robert Downey Jr.'s Iron Man.
