The evil AI known as Ultron is one of the Avengers' most powerful and dangerous foes, with a murderous drive to replace all organic life on Earth with robots and androids like him and the raw power to challenge the entire team of Earth's Mightiest Heroes.
Now, as of January 31's Avengers Inc. #5, he's back in the mainstream Marvel Universe in a surprising new form that ties into the series' overall mystery. What's more, Ultron also rears his head in Avengers: Twilight #2, also out on January 31, bringing a double dose of Ultron to the Avengers and potentially setting the villain up for an even bigger return in the near future.
