8 Superheroes Who Saw The End Of The World
2. A Few Surviving Marvel Heroes - Age Of Ultron
Prior to 2015, Age of Ultron wasn't just the name given to a mildly annoying MCU film from Joss Whedon. A couple of years before then it was actually a major comics event from writer Brian Michael Bendis and artists Bryan Hitch and Brandon Peterson.
Apart from the name and antagonist, the comic shares nothing in common with the film. It's not an origin story, and instead opens with a version of Earth ruled by Ultron, with Earth's Mightiest Heroes waging an underground resistance against the robotic despot.
Things have very much not gone according to plan in this future, with plenty of Marvel heroes dead as a result of Ultron's resurgence and things not looking rosey at all. The surviving heroes travel into the future to stop Ultron before he can travel back in time and conquer the planet (it's... slightly confusing), while Wolverine and Invisible Woman travel back to kill Hank Pym before he creates Ultron in the first place.
As one would expect the solution isn't as simple as it sounds, and things go from bad to... not quite as bad (but still bad). Whatever the case, those issues where we got to see the world ruled by Ultron were definitely up there with the freakiest Marvel dystopias.
