How about that Avengers: Age of Ultron trailer, eh? What an entrance! We’ve come a long road and seen a lot of Marvel films to get to this point, and it seems certainly well earned. You may be wondering, though, who is this Ultron fella that seems to be creeping out our heroes by shambling into Tony Stark’s pad? What’s his deal and where does he come from? In the comics, Ultron is, arguably, the major Avengers villain as he is first and foremost an antagonist to the group itself, rather than say Loki who’s really more of a Thor villain. While the origin of Ultron may be different in the movie, we thought we’d walk you through the birth and “life” of this sinister automaton who has been a thorn in the Avengers side for so long. Get better acquainted with the comics history of Ultron after the jump.
