What Is a Mummudrai?
The term used to describe Cassandra in the comics is that she is Charles’ “Mummudrai,” a term that comes from the theology of the Shi’ar, the interstellar imperialists who’ve long been a part of X-Men continuity’s connection to the realm of the Marvel cosmic. According to the Shi’ar, every living being has their own Mummudrai, a bodiless spirit on the Astral Plane that reflects the “anti-self”—the complete inverse of their organic counterpart. Every living being, before birth, faces the their Mummudrai and defeats it on the Astral Plane, as part of the birthing process.
Mummudrai are made up of emotional energy, and don’t usually take physical forms. Cassanda is the most famous in the comics, but they’ve appeared a few times here and there since New X-Men.
