Cassandra Nova remains one of the X-Men's most chilling villains, primarily remembered for orchestrating the Genosha genocide in Grant Morrison's New X-Men run (a storyline that still haunts fans decades later). Frank Quitely's unsettling depiction of her psychic battle with baby Xavier in the womb has become iconic, cementing her status as a uniquely disturbing threat. Emma Corrin's performance in Deadpool & Wolverine introduced her to wider audiences, though comic readers appreciate the character's deeper psychological horror and her role as Professor X's mummudrai twin.
