The listing, UNCANNY X-MEN issue 456 has ended.
While Psylocke waits imprisoned in the X-plane and has a strange encounter with her mad brother on the Astral Plane, the X-Men are ambushed and do battle with a band of costumed humanoid dinosaurs. The dinosaurs use their superhuman abilities to usurp Rachel’s mind causing her to think she is a dino-mutant. Rachel turns her telepathy against her teammates and helps the dinosaurs defeat the team. The X-Men are taken captive and carried through a glowing portal. X-23 alone escapes and frees Psylocke from the X-plane who single-handedly defeats the remaining dino-humanoids; together, she and X-23 enter an open portal to rescue the kidnapped X-Men including Wolverine.
