X-Men: 10 Worst Things The Mutants Have Done

Cassandra Nova is Charles Xavier's twin sister who would serve as a foe for the X-Men in the 2000s.

After her initial defeat, she would later manipulate Emma Frost to do her bidding and perform a psychic assault on each member of the super-team. This ranged from reducing Cyclops into a catatonic state, to turning Beast into a wild animal, but the one who got it the worst has to be Kitty Pryde.

First, Kitty is placed in a dream world where she has lived happily ever after with Piotr Rasputin, aka Colossus. She then gives birth to a child that she names Michael and raises him for the next three years. But one day, the X-Men arrive and take their son away from the couple as Professor X believes the infant to be a threat. Piotr even betrays his spouse and knocks her out to surrender Michael to their former allies. This pushes Kitty to find the boy at all costs, not knowing that she has been manipulated by Nova in an attempt to return her to power.

Though the events that transpire are mere hours, in Kitty's perspective, she had lived those three years which makes her loss even more painful.
