Scarlet Witch/Wanda Maximoff is the newest female in the Marvel Cinematic Universe, and she might be the most powerful. Introduced in the comics in the 1960s, Scarlet Witch is known as a longtime member of the Avengers. However, “Avengers: Age of Ultron” won’t show her as a hero right away. She and her brother Quicksilver/Pietro Maximoff (Aaron Taylor-Johnson) will be fighting the superheroes. Actress Elizabeth Olsen revealed how her character’s powers work, and it turns out that Scarlet Witch can do a lot more than just move things with her mind. 

1. She’ll feel the Avenger’s emotions. “Yeah, so I am able to go into someone's head and they'd never see. I can feel and see what they feel and see. So it's not just me manipulating them,” Olsen explained to IGN. “What I love about her is that, in so many superhero films, emotions are kind of negated a bit, but for her everything that someone else could feel -- like their weakest moments -- she physically goes through that same experience with them, which is pretty cool. Yeah, like if they have the biggest, darkest fear, I get to see that.”

Though Scarlet Witch will start out as an adversary, eventually, she joins the Avengers. Going into their heads and experiencing their feelings might give Wanda the insight she needs to realize that she shouldn’t be fighting against the superheroes.

2. Scarlet Witch will bring up the Avengers’ pasts. “She can make you have a nightmare, is one way of putting it,” director Joss Whedon told BuzzFeed. “‘Trip balls,’ would be another one.” He confirmed that she is the reason Hayley Atwell (Peggy Carter, Captain America’s former flame) and Idris Elba (Heimdall, Thor’s friend) appear in the film. She'll make the heroes recall faces from their pasts. Fans first noticed the actor’s names on the movie poster and speculation about flashbacks started immediately. It might not be a pleasant memory or dream if Wanda is trying to take down the team.

3. Her powers don’t end there. Those who stuck around for the post-credits scene in “Captain America: The Winter Soldier” saw the first scene with the Maximoff twins, Scarlet Witch and Quicksilver. They already know she can move objects with her mind, but that also applies to energy. “Yeah, I can control energy. I can manipulate energy, so that's what the red stuff is that we're playing with,” she said.

Also, the twins clearly know how to use their powers, so "Age of Ultron" isn't about figuring out how they work. They'll take full advantage of their abilities to fight their enemies. 

4. She’s from a fictional place. After hearing her brother Quicksilver’s accent for the first time in a recent trailer, many thought the accent was Russian. However, it seems the twins will be from a fictional location. “We know that we're from Eastern Europe,” Olsen clarified. “It's a make-believe place, so it's something that Aaron and I -- with the dialect coach -- kind of created together.”

The comics used the fictional country Transia as their home. The country was said to be located between Romania, Macedonia and Serbia, and that would certainly explain the eastern European accent. This might be one original detail that Whedon decided to keep. 

5. Dance influenced her movement. Scarlet Witch will look pretty graceful in the film because Olsen worked with a choreographer. “So we started off with Joss kind of having these ideas based off just images in the comics, of what the hand gestures would look like or the arms, and then I worked with a dancer, Jenny Wade,” she said. “She's a choreographer and dancer. So the two of us get locked up in a room together, and we move and we try and figure out what looks strong, where the energy comes from.”

The actress noticed that her moves weren’t quite as tough as other actor’s stunts. “It's funny, because everyone's doing stunt practices and choreography, but she and I are just doing weird moves and s---, you know, pretending we're making things shoot out of our hands,” Olsen laughed.

6. She relies on her brother. In a new video from Marvel, Maria Hill (Cobie Smulders) explains that their parents were killed when the twins were only 10. They might not have a team, but these two will certainly look out for each other. “They only have one another,” Taylor-Johnson explained. “It's kind of just them against the world.”

7. Scarlet Witch and Quicksilver hate the Avengers. They aren't exactly signing up to join the superheroes. Director Joss Whedon explained that they don’t view the Avengers as the protectors of the earth. “They don’t like America, and they don’t like the Avengers,” Whedon told BuzzFeed. “The Avengers are like a world power, and not everybody’s on board with the Avengers coming in and starting fights, even in the name of justice. So you need that dissenting voice, and you need to understand it and sympathize with it.”

Will they feel the same way by the end of the film? Though the Maximoff twins will eventually join the Avengers, they don’t have to right away. With two more sequels on the way, these characters could easily take their time to make that transition.
