X-Men (The Last Stand)

A pharmaceutical company called Worthington Labs announces that it has developed an inoculation to suppress the X-gene that gives mutants their powers and makes them different from humans, offering the "cure" to any mutant who wants it. While some mutants are interested in the "cure", including the X-Men's Rogue, many others are horrified by the announcement. In response to the news, the X-Men's adversary Magneto raises an army, warning his followers that the "cure" will be forcefully used to exterminate the mutant race.

While Mystique was on the prison, Magneto plannned to escape Mystique. Upon freeing Mystique, they also freed Juggernut. One of the guards was awaken and pointed the gun with cure to Magneto. Mystique covered Magneto so she was the one who was hit. She was left in the prison cell with human form. Magneto told Mystique that "I am sorry my dear but you're not one of us anymore."

Cyclops, still depressed about the loss of Jean Grey, returns to Alkali Lake, where Jean sacrificed herself to save the X-Men. Jean appears to Cyclops, and as the two kiss, Jean changes and appears to kill Cyclops. Sensing trouble, Professor Charles Xavier sends Wolverine and Storm to investigate. When they arrive, the two X-Men encounter telekinetically floating rocks, Cyclops' glasses, and an unconscious Jean.
Xavier explains that when Jean sacrificed herself, she unleashed the powerful alternate personality she calls "Phoenix". Wolverine is disgusted to learn that Xavier has kept Jean in check telepathically, but when Jean awakens, he realizes she is not the Jean Grey he knew. Jean pleads with Wolverine to kill her, but when he refuses, the Phoenix surfaces and telekinetically slams Wolverine into a wall. She then escapes to her childhood home.
Magneto, also aware that Jean is now a powerful mutant, meets Xavier at Jean's house. The two men vie for Jean's loyalty until the Phoenix resurfaces, unleashing her devastating power. She destroys her family's house, disintegrates Xavier, and leaves with Magneto.

Following the loss of Xavier, the X-Men regroup and confront Magneto's army, which is attacking the pharmaceutical company's laboratory on Alcatraz Island. During the fight, Beast injects Magneto with the "cure", nullifying his mutant powers. While they were fighting They told Kitty to follow Juggernut to get the "Cure". Kitty used her power to pass through the walls and put Juggernut on the ground. After, Kitty ran away. Juggernut was shouting that "Don't you know me, I am the Juggernut bitch!". Juggernut was able to escape and followed Kitty. Upon reaching at the cure, Kitty tried to use her power but she can't use it if she is with the cure. Juggernut arrived and Kitty told him to "Come on you dickhead!" Juggernut was down after it.

After the battle, the Phoenix emerges and begins to destroy everything and everyone around her. Momentarily gaining control, Jean begs Wolverine to save her. Telling Jean he loves her, Wolverine reluctantly kills her with his claws.

Despite the X-Men's losses, life goes on. Magneto, now an ordinary man, sits at a chessboard and reaches out toward a metal chess piece that trembles slightly.

And that's the end of the third part of X-Men (The Last Stand).
