This variant of Cassandra Nova Xavier was an Omega level mutant and the twin sister of Charles Xavier, who she tried to strangle in the womb with her umbilical cord. Not long after she and Charles were born, Cassandra was deemed a danger to the multiverse by the Time Variance Authority, and was banished to the Void. As she grew into an adult, Cassandra found the barren, ruined wasteland the ideal place to explore and perfect her telekinetic abilities and tactile telekinesis without restraint.
