Joss Whedon has definite ideas about how he wants to change Ultron, the sentient robot who will be the main villain in Avengers 2. Created by Hank Pym (Ant-Man/Giant-Man) and imbued with the scientist’s brain patterns, the super sentient robot Ultron has a serious Oedipal complex as well as many powers in his comic iteration including superhuman strength, speed, stamina, durability, plus he can fly at subsonic speeds and repair himself when injured. His offensive repertoire also includes energy blasts and an "encephalo-ray" that can place its victims into a coma, but also allows Utron to hypnotize and control his victims.
Whedon plans to cut back on those powers in Avengers: The Age of Ultron. In a wide-ranging 10-page interview in the issue of EW that goes on sale on Friday, the director explained: "I knew right away what I wanted to do with him. He’s always trying to destroy the Avengers, goddamn it he’s got a bee in his bonnet. He’s not a happy guy, which means he’s an interesting guy. He’s got pain. And the way that manifests itself is not going to be standard robot stuff. So we’ll take away some of those powers because at some point everybody becomes magic, and I already have someone (Scarlet Witch) who’s a witch."
Whedon told EW that he will have to be careful "to ground (Ultron) while still evoking that guy." But there is little doubt why Whedon chose to make Ultron the focus of the Avengers sequel, "As a character I love Ultron, because he’s so pissed off."
