Between the X-Men films never being strong sticklers for continuity and the Deadpool movies almost feeling entirely separate from the franchise’s other entries, Shiolo Kutsuna’s Yukio should basically just be considered an all-new character.
It’s important to mention that this isn’t the first time we’ve seen a version of Yukio in the X-Men film franchise.
While Rhett Reese expressed interest in exploring Yukio more, it remains to be seen if she’ll be brought back for Deadpool 3 or X-Force.
She was previously portrayed by Rila Fukushima in 2013’s The Wolverine, but this Yukio more closely resembled the version from the printed page, although she was also a mutant who experienced visions of the future.
