Age of Ultron

The Age of Ultron was caused by Ultron, it was the name given by the Avengers for his evil plot, which was a new age.

Ultrons plan was to eliminate everyone on Earth and start a new age of mankind, a age of peace, not one of war and murder. But of course, the Avengers were against that and went after him attempting to stop him, finally facing off with him in Sokovia alongside new members like Captain Marvel, War Machine, Moon Knight, Scarlet Witch, Quicksilver, Vision, and The Falcon
