To prep fans for the film “Avengers: Age of Ultron” arriving May Day, Marvel Studios has been releasing single-character posters for the past couple of weeks. While the previous posters have revisited characters we already know and love, the newest batch highlight two newcomers to the “Avengers” team.

Marvel began by releasing the first full-scale cinematic poster for the movie. Afterward, characters such as Iron Man (Robert Downey Jr.), Captain America (Chris Evans), Hawkeye (Jeremy Renner) and even Nick Fury (Samuel L. Jackson) all appeared in killer posters of their own. Available for viewing via IGN, the posters feature the characters with devious Ultron robots bearing down on them. Now, the twins Pietro Maximoff and Wanda Maximoff have been given the same star treatment.

Quicksilver (Aaron Taylor-Johnson) and his sister Scarlet Witch (Elizabeth Olsen) have been teased for quite a while now. While their comic-book counterparts have an incredibly rich backstory in relation to “The Avengers,” not much is known as to how writer and director Joss Whedon will work them into his highly anticipated production.

According to Yahoo Movies, Quicksilver can move at superspeed, while Scarlet Witch can manipulate reality. As the trailers have shown, she’s got the ability to give people visions and some telekinetic powers. The characters are technically mutants, but the word mutants cannot be mentioned in the Marvel Cinematic Universe (MCU), because all things “X-Men” are owned by Fox. Due to the fact the Marvel comic-book characters have such a deep affiliation with the Avengers, however, they’re legally allowed to appear in “Avengers: Age of Ultron.”

In the comic books, the twins wound up becoming members of the team, and Scarlet Witch even engaged in a romantic relationship with fellow “Age of Ultron” newcomer, The Vision (Paul Bettany). Still, it’s unclear how the film will explain their apparently magical powers. CinemaBlend noted they will likely be used to springboard the MCU into its forthcoming “Doctor Strange” flick, starring Benedict Cumberbatch as the sorcerer who will introduce actual magic into the comic-book movie world.

Judging by the recently released third trailer for the film, it looks like the Maximoffs will begin the movie on the side of the villainous robot Ultron (James Spader) before turning over a new leaf and joining the rest of the superpowered team for a final throwdown with some robot drones.

“Avengers: Age of Ultron” will bring Scarlet Witch and Quicksilver to life when it hits theaters May 1. Until then, fans will have to just keep rewatching the trailer we’ve posted below.
