11. ...And Uses It To Create His Own "Vision"
As was rumoured early in the production process, it may be Ultron and not Tony Stark who creates the Android Avenger, and it seems that it is Ultron's ego and his desire to prove that he is superior to humanity (the same compulsion that makes him want to wipe them out) drives him to want to be a creator. He is compelled by the singular urge to prove that he is better than his own creator - hence the puppet/Frankenstein imagery that was so heavily featured in the first trailer - and the sceptre will provide him not only with the power to create "life" (something he's already achieved with his drones) but also to create super-powered (and thus superior) life. Something goes wrong however, and it could be that Banner and Stark simply reclaim Vision and turn him to their side.
