The Days of Future Past film was unique take on a story first told in pages of Uncanny Men #141 and #142. the film,
Kitty sends Wolverine back in time to stop something that would lead to future ruled by mutant-hunting sentinels. the comics,
however, Kitty was the time traveling hero.
Tasked with the same mission as Wolverine in the film, comic
book Kitty was sant back into the body of her younger self by
Rachel Summers. Since Kitty was co young in the film's depiction, she woulda't have a younger bedy to go to; she wasn't even born in 1973. So, she was given Rachel's original role and, sadly, that ts
the only version some fans will ever know.
