In an interview with with Lorraine Cink, Joss Whedon revealed that a Marvel Character, apart from The Avengers, Ultron and other characters who we've seen in the trailers and posters will be appearing in Avengers : Age of Ultron. Here are some characters who might possibly appear in the movie.
Since the announcement that Spider-Man is coming back to MCU, fans have desperately been waiting to hear the news of this beloved superhero's appearance. But with no confirmation as to who will be playing the web-slinger, his appearance might be unlikely.
2. Black Panther
This might be the most likely scenario as we already know that Ulysses Klaw (played by Andy Serkis) will be appearing in the movie and also the fact that The Avengers will be seen kicking some ass in Wakanda, the home of T'challa.
With Ant-Man releasing just two months after Avengers : Age of Ultron, the appearance of this superhero in the post-credits scene doesn't seem like a bad idea.
A few days back, we saw a glimpse of the Avengers Tower in the trailer of the Daredevil TV show. Can we now see "the Man Without Fear" appearing in Avengers : Age of Ultron? Only time will tell.
5. Guardians of the Galaxy
Many of us already know that the Guardians of the Galaxy are connected to the third instalment in the Avengers franchise, Avengers : Infinity War Part 1 and Part 2 which are slated to release in 2018 and 2019 respectively. So there is a good chance we might see any one or more of the Guardian(s) in a special appearance.
