Brook is the half-sister of River, who is a hero member of the Defenders. River and Brook are both daughters of the aqua-villain Fathom, who is the son of Aquarius, leader of the Celestials. When River was born, she was put into the care of her mother and raised a loving, good person. But two years later, Brook was born of a different mother, and Fathom stole her away to raise her to help him commit crimes and spread chaos across the country.
