Did Iron Man have a role in creating a new villain? The plot synopsis of "Avengers: Age of Ultron" hints at the origins of the new villain. Fans of the franchise will also get to see some new characters introduced in the movie. The movie is slated to be released in 2015.

Earth's mightiest heroes will have to assemble once again to face a grave new villain. According to the official synopsis shared by IGN, something goes wrong when Iron Man tries to work on a dormant peacekeeping program.

As things do not go as planned - Captain America, Thor, Hulk, Black Widow and Hawkeye join Iron Man to fight against Ultron. Three new characters in "Avengers: Age of Ultron" are Wanda Maximoff, Pietro Maximoff and Vision. They are joined by the familiar Nick Fury and Agent Maria Hill.

Wanda and Petro Maximoff are twins. Comic book fans would know them better as Scarlet Witch and Quicksilver. The two have been a part of Magneto's group but were later seen joining the "Avengers" group in the comics.

The character Vision was an android created by Professor Phineas T. Horton in the comic books. He is seen fighting for Ultron initially but later switches sides and fights for the "Avengers" in the comic books.

The cast of "Avengers: Age of Ultron" include Scarlett Johansson as Black Widow, Chris Evans as Captain America, Robert Downey Jr. as Iron Man, Chris Hemsworth as Thor, Mark Ruffalo as Hulk, Jeremy Renner as Hawkeye, Samuel L.
