Cassandra Nova is a formidable and sinister villain in the X-Men universe, known for her extraordinary powers and relentless pursuit of revenge against her brother, Professor X. This enigmatic mutant, born as Charles Xavier’s genetic mirror, possesses a vast array of psionic abilities, including telepathy, telekinesis, and the power to manipulate her physical form. Her deep-seated hatred for Charles stems from their shared origin in the astral plane, where she formed as his dark reflection. Cassandra’s malevolent nature led her to unleash a devastating genocide on the mutant population of Genosha, resulting in the deaths of millions. Despite her apparent defeat, Cassandra’s legacy continues to shape the X-Men’s world, with her presence looming over current adaptations such as the Disney+ series and the upcoming film.
