10 Little Known Supervillains That Could Make Marvel Millions

9. Cassandra Nova

Mephisto Marvel
Marvel Comics

Cassandra Nova was a Mummudrai. According to Shi’ar beliefs, these were parasitic spirit-like beings who represented the exact opposite any person they were associated with. The legend was every person had to overcome their own Mummudrai before being born. In Cassandra’s case, she served as the Mummudrai to none other than Charles Xavier.

Now because of Charles’ enormous latent power, Cassandra was able to attain a physical form, becoming his twin. The future Professor X sensed her evil presence, and initiated a battle inside the womb. This caused Sharon Xavier to miscarry Nova and Charles was born as a sole child. Or so it was believed.

For as it turned out, Nova had survived and spent years developing from a mass of cells, into a full bodied mutant. Hell-bent on taking revenge on Charles, she manages to gain use of an army of extremely powerful Sentinels and sends them on a rampage against the mutants.

This culminates in one of the worst massacres in comic history when her Sentinels slaughter around 16 million mutants. Her efforts are ultimately thwarted by the X-Men but with a resume as bloody as this, the future X-Men reboot within the MCU, could very well use her to lucrative effect.
