Rachel Anne Summers (also known as Rachel Grey) is a fictional character appearing in American comic books published by Marvel Comics. The character was created by writer Chris Claremont and artist/co-plotter John Byrne. In her first appearance, the character's surname was not revealed; in later appearances, she was established as the daughter of the alternate future counterparts to Cyclops and Jean Grey-Summers from the dystopian Days of Future Past timeline, making her the sister of Nate Grey and half sister of Cable as well as the niece of Havok and Vulcan. Although she is considered a unique multiversal anomaly with no alternate-universe counterparts, this has been contradicted by references to her stated relationships to certain characters in other dimensions. The character is a mutant with similar abilities to her mother, including telepathy, telekinesis, and a connection to the Phoenix, the latter of which was represented in her adoption of the Phoenix title after her mother's apparent death. Throughout her publication history, she has also been referred to by the monikers Marvel Girl, Prestige, and Mother Askani, most recently taking on the codename Askani. Publication history Rachel first appeared in The Uncanny X-Men #141 (Jan. 1981) and has since been affiliated with several comic book superhero teams including the X-Men and Excalibur.

The title was the follow-up to the 2019's Excalibur relaunch and was written by Tini Howard. In its fourth issue, Rachel Summers and her long-time friend Betsy Braddock confessed their romantic feelings for each other and their kiss was shown in a splash page.
