Banner and Stark move their hands around in the air a whole bunch and use CGI virtual computer screens to create Ultron, a computer program similar to Avengers favorite, the disembodied manservant Just A Rather Very Intelligent System (J.A.R.V.I.S.). As the pair head out to party with their teammates, Ultron takes over J.A.R.V.I.S (voiced by Paul Bettany) and Starks' armored army. Now that Ultron has a body, he hides out in the former lair of Baron Von Strucker and uses HYDRA tech and the staff of Loki from the first film to create drone Ultrons. He's also joined by two new characters: Wanda "Scarlet Witch" (Elizabeth Olsen) and Pietro "Quicksilver" Maximoff (Aaron Taylor-Johnson), the brother and sister team who were given their powers in the film by the aforementioned Strucker, and have a hatred for Tony Stark after they were left in a collapsed building as children waiting for one of his bombs to go off. Ultron plans to use the pair to "tear the Avengers apart from the inside" using Wanda's mind-control power and Pietro's super speed.
