10 Unbelievable Marvel Plot Twists That Shocked The World

Let's face facts here. The Avengers event, The Crossing, wasn't the greatest story ever told. In fact, it wasn't that good at all. But it did have a WTF moment that deserves inclusion here, and that was Tony Stark turning evil, getting killed, and then returning as his teen self.

When a time-traveling Kang drops in on an earlier rendition of Marvel's supergroup. After failing to brainwash Hank Pym, he turns his attention to Iron Man, who he has much more success with.

This turns Tony into a murdering machine and he takes out Yellowjacket, Gilgamesh, and Crystal's nanny (for some reason), and when the rest of the Avengers finally figure out what's going on, he tries to off them as well.

Figuring out that the only way to best Iron Man is to go even further back in time and bring a young version back to the future with them, they do just that. Unfortunately for Teen Tony, it doesn't quite go according to plan, and Adult Stark nearly kills the bejesus out of him as well.

In the end, Older Iron Man sacrifices himself to save everyone, leaving the younger version of himself to fill his metal shoes.
