Inspired by the X-Men animated series two-parter One Man's Worth, the Age of Apocalypse was the first X-Men crossover event of its kind. It literally took over the entire X-Men line to tell the tale of what happened to the world after David Charles Haller, otherwise known as Legion, traveled to the past and mistakingly murdered his father, Professor Charles Xavier. The act radically changed the flow of events following the incident. Most notably, the X-Men were not formed by Xavier, but Magneto. And under his leadership Apocalypse, one of the X-Men's most powerful foes plunged the world into chaos, eventually taking over most of North America. Under his rule a large portion of the human population and any mutant not deemed strong parished or sent to languish in breeding pits. Eventually the time period was repaired and most of this nightmare fades into nothing, but even years afterwards, the wounds it created are still felt.
The story was brutal and at times heartbreaking as we saw many of our heroes either die grusome deaths or be transformed into deranged evil mirror versions of themselves. As tragic and twisted of a tale it was, it had some of the best and bravest storytelling we've seen since the creation of the franchise. What are your favorite parts of that storyline? What do you remember most?
