Cassandra Nova, a formidable villain in the Marvel Universe, particularly within the X-Men series, is the malevolent twin sister of Charles Xavier. Created by Grant Morrison and Frank Quitely, she is a mummudrai, an astral parasite, who embodies the dark and destructive aspects of Xavier's psyche. Possessing immense psychic powers, Cassandra Nova is capable of telepathy, telekinesis, and cellular manipulation. Her hatred for mutants and relentless pursuit of their eradication make her one of the X-Men's most dangerous adversaries. Nova's intellect and ruthlessness are matched by her cunning, as she orchestrates devastating attacks against the mutant community, including the genocide of the mutant population of Genosha. Her complex relationship with Xavier adds a profound psychological dimension to her character, making her a uniquely unsettling and deeply personal foe for the X-Men. Base your audition off of Cate Blanchet's Hella from Thor: Ragnarok.
