In another multiverse, there's some whacko garbage- ahem, there's Astria Chavez-Khan, daughter of Kamala Khan and America Chavez, and her best friends, Univa Maximoff and Amaya Parker. They're in a heap of trouble when Anastasia Bishop, who comes from an AmeriKate multiverse, decides she's jealous of Astria and her family.
I do not care if Night Star is already used in the MCU- if there can be two Captain Marvels, there can be two heroes/hero-villains with the same name. Deal with it. Also yes I wrote the story as a screenplay, it was harder to write everything as a normal story. I don't know if this counts as a fanfic though.
