Created by writer Jonathan Hickman and artist Pepe Larraz, she first appeared in X-Men (vol. 5) #12 (November 2020). She is a mutant whose powers prevent her from ever losing. Isca lived on the ancient island of Okkara and was the younger sister of Genesis. When the Amenthi Daemons invaded the island and split it into Krakoa and Arakko, Isca initially fought alongside her fellow mutants. However, when it became clear that the forces of Annihilation were going to win, her powers compelled her to defect to the Daemons. After the entire mutant population and Arakko were sealed away in Amenth to stymie the invasion, Isca continued to fight against her people for Amenth. After millennia of battle, Annihilation sent Isca to her sister Genesis with a proposal for the queen of Arakko to face the dark ruler of Amenth in a duel to the death and end the war. This was ultimately a trap: by killing Annihilation's host, Genesis was forced to become its new host in order to prevent the uncontrolled Daemons from destroying Arakko.

At the battle's conclusion, Isca traveled to Earth with the rest of the Arakkii mutants and claimed a seat on Arakko's ruling body, the Great Ring of Arakko (though she abstained from voting so her powers would not influence other members' votes). She later assisted Magneto in terraforming Mars to be a suitable home for Arakko and traveled there when the island was relocated. Isca's service in the Great Ring was marked by frequent ideological clashes with Storm, the new Regent of Arakko. During the duel between Magneto and Tarn for the latter's seat on the Great Ring, Sunspot tricked Isca into wagering against Tarn, resulting in her lover's death. When the Eternals declared war on mutantkind and sent Uranos to attack Arakko, Isca's powers compelled her to defect to their side and she killed fellow Great Ring member Idyll the Future Seer.
