Not 5 minutes just after Ultron is alive (and even before he gets a human body), he kills J.A.R.V.I.S. For his element, Tony will get defensive about Ultron as a strategy. Wanda permits Tony to choose Loki's scepter, believing he would destroy himself with it since that happened to absolutely everyone else whoever touched it. Speedster Pietro is a lot more hands-on in overcome, though Wanda relies on her telekinesis.
