It has been several months since The X-Men stopped William Stryker, but
that victory came at a price, they have lost Jean Gray when she tried to
save them from the collapsed reservoir. Scott Summers (Cyclops) is still
grieving about her loss. One day, he came out to the place which is where
Jean Gray sacrificed herself. Then, Jean Gray appeared right in front of
him. Though, it seemed that after that, Scott had disappeared. Meanwhille,
the rift between humans and mutants had finally reached the boiling point.
When humans discovered what causes humans to mutate, they have found a cure
for the mutation. The X-Men were appalled at this idea. It was not long at
all until the news about the cure came to Magneto. He decides to organize
an army of mutants and wage his war against the humans. Then, it became
clear that Jean Gray evolved into the Pheonix, her new mutant powers are so
strong that she can not control her own body. Then, she kills off Professor
X with her new powers. Now, The X-Men must stop Magneto again and put an
end to the war against the humans, as well as stop Jean Gray's Pheonix
powers.
When a cure is created, which apparently can turn any mutant into a normal
human being, there is outrage amongst the mutant community. Whilst some
mutants do like the idea of a cure, including Rogue, many mutants find that
there shouldn't be a cure. Magneto, who still believes a war is coming,
recruits a large team of mutants to take down Warren Worthington II and his
cure. Might seem easy for the X-Men to stop, but Magneto has a big
advantage, which Wolverine doesn't have. Jean Grey has returned, and joined
with Magneto. The Phoenix has woken within her, which has the ability to
destroy anything in here past, even if that 'anything' is a X-Men.
The X-Men, mutant heroes sworn to defend a world that hates and fears them,
are back! This time, with the help of new recruits The Beast and Angel,
they must face evolution itself in the form of their former teammate, Jean
Grey. Possessed with the cosmic power of the Dark Phoenix, the resurrected
Jean Grey has become a danger to herself, her mutant comrades, and the
entire planet. To stave off this imminent threat to humanity, a potential
cure is discovered and processed to treat -- and ultimately eliminate --
genetic mutations, once and for all. Now, as the battle lines are drawn,
the X-Men, led by Professor Charles Xavier, must contend with both Jean
Grey's world-consuming powers, as well as the malevolent Brotherhood, a
band of powerful mutants organized under Xavier's former ally, Magneto.
Mutants are on the verge of X-tinction, it seems, when US business
Worthington Industries discovers a cure for mutation. This scientific
breakthrough complicates and intensifies the battle - both physical and
ideological - between Professor X's integration-friendly X-Men and the
human-hating muties let by Magneto ...
When a private laboratory supported by the government finds the cure for
the mutants, using the DNA of a powerful boy, the mutants have the option
of giving up their powers and become human, but their society split.
Magneto opposes and decides to join a force to fight against the government
and kill the mutant boy. Meanwhile, Jean Grey resurrects uncontrolled by
Xavier and with the personality of the powerful Dark Phoenix. She destroys
Cyclops and Professor Charles Xavier, and allies to the evil forces of
Magneto, making them almost invincible.
