2. Scarlet Witch
The Maximoff twins were the big new additions to the cast for Age Of Ultron, but unfortunately only one of them has lived to fight another day. Scarlet Witch, after the death of her brother, is now a part of the Avengers, and she'll presumably be fighting alongside Cap and co in this film. I really liked the character and Elizabeth Olsen's portrayal in Age Of Ultron, and have very high hopes for her going forward. She has the potential to be one of the most powerful characters in the entirety of the MCU, and will hopefully be playing a big part in the future. On the other hand, she's been quite absent so far in the build-up to the movie. She wasn't a part of the image that was revealed showing the two sides, and Olsen
has described her character as a "wild card." That makes her role in this movie one of the most intriguing. Will she be responsible for starting the war? Is she going to play both sides, or switch halfway through? Although I'm hopeful she will survive, her being a 'wild card' really does increase the chances of her dying.
