MARVEL with her role as a leader in the new community — but her conflicted identity has come at a deep personal cost. Now, pulled into the distant past by an unhinged villain with deep ties to mutant history, Ms. Marvel will witness the iconic birth of the Uncanny X-Men and their first encounter with Krakoa from an all-new, all-different perspective. But when history begins to change... can either Kamala Khan or the X-Men themselves survive the experience?
