Fan Casting Mind Stone Stolen in Avengers vs X-Men (2015)

In a SHIELD bunker, guards protect something valuable behind the vault in that bunker. Then, a helicopter landed on the pad. It was an unexpected arrival of Nick Fury, director of SHIELD. He had come to take a look at what they found in Sokovia. Then they lead him to the vault, revealing a marvelous yellow gemstone. They say it had fallen from space and landed in Sokovia. Their scientists began testing it, and it turns out it gives people illusions to the mind, making them relive past memories, and even controlled their minds. Fury says "Thank you", but in a female's voice. Then his one eye turned yellow, and he kicked down the guards, took one of their guns, and shot them all down. Then the Nick Fury imposter revealed herself to be Mystique, which can only be one thing: Magneto. She gets out a communicator and tells Magneto that it's clear in the vault. Erik Lehnsherr comes out of the helicopter and goes through the bunker, killing the rest of the guards on his way to the vault. Then he sighs in astonishment, saying that "At last, humanity will know the punishment for killing and suppressing our mutant brethren."
