Recently released concept art showing the two sides facing off featured a notable omission. Aside from Hulk and Thor (who we figured wouldnt be making an appearance anyway), Scarlet Witch was conspicuous by her absence: odd, considering that shes front and centre in Captain Americas Caffeine Free Avengers line-up at the end of Avengers: Age Of Ultron. In recent interviews, the actress behind the weird hand movements of the Witch, Elizabeth Olsen, has declared that Wanda Maximoff is the wildcard in the deck, and that theyve been working hard on a new way of portraying her powers, calling it a transformation. At one point in the comics, the Scarlet Witch has the power to bend and shape reality to her whim on an almost limitless scale, which is definitely the kind of ability that Stark might consider required regulation. But would that mean controlling her or recruiting her? And how would newborn magic robot the Vision feel about that? In the comics, Wanda and the Vision are an item, and even marry, and Avengers: Age Of Ultron certainly teases the possibility of that relationship arc coming up in the MCU. Is Stark moving against the Scarlet Witch, an Avenger, the catalyst for conflict in the film? Maybe well see a hint of their plans for her in the trailer.
