X-Men (Xavier Institute member) (leader); formerly Guardians of the Galaxy, partner of Star-Lord, X-Men (New Charles Xavier School member), X-Men (Young) (tutor), Excalibur (founding member), S. Professor Charles Xavier located Kitty and set to recruit her for his school, and possibly as a new member of his X-Men.
After the X-Men saved Senator Kelly, Kate Pryde's consciousness left Kitty's body and returned to her own time, only to find her timeline had not changed. Later, Kitty was almost kidnapped by deformed mutant Caliban.
Caliban, who only sought friendship, return to his underground home.
While battling the Brotherhood of Evil Mutants, Colossus was frozen in liquid nitrogen.
While attempting to save Colossus, Kitty was kidnapped by Callisto, who intended for her to keep her word and marry Caliban, but Caliban released her from her vow, hoping she would one day return to him of her free will, and Colossus was saved by the combined efforts of Rogue and the Morlock, Healer.
One problem in their relationship was that Kitty was a devout Jew and Colossus was raised as an atheist. As the X-Men confronted Dracula over Storm, Kitty was temporarily possessed by Lilith and bit Piotr (Peter) Rasputin.
