Cassandra Nova is a Mummudrai, a bodiless parasitic life-form, originally living within Charles Xavier. She has formed her own body by copying Xavier's DNA.
History
First Battle: Cassandra Versus CharlesOrigin
Cassandra Nova began life the same instant Charles Xavier was conceived. The only exception is she was conceived without a body, so she improvised. She took Xavier's DNA and copied it (literally splitting Charles unborn zygote) to make her own body, effectively becoming his twin sister. She then grew with her brother until the time when Charles sensed its monstrous thoughts, Charles attempted to kill the creature resulting in its physical body being stillborn. However, the creature survived as chaotic cellular matter and clung to a sewer wall for decades, rebuilding its physical form and perfecting its effort to mimic human traits.
Jean Grey later discovered that Cassandra Nova is the mummudrai (from a Shi'ar legend, meaning opposite) of Charles Xavier. "Legend says each of us faces our own personal mummudrai in the womb, shortly before birth - it is our first experience of the alien, the other, the different". In reality, the mummudrai are a parasitic species born bodiless as psychic energy (generally within the mind of the original), and it was only through becoming entangled with Charles Xavier's developing telepathic mind that Cassandra Nova created a body for herself.
Genosha Genocide
Killing Trask to Gain the Sentinels
After she was able to rebuild herself, Cassandra returned with a vengeance. She convinced the last living relative of Bolivar Trask, Donald Trask III, to activate a pair of enormous wild Sentinels and send them to destroy the mutant homeland of Genosha, killing 16 million mutants. Cassandra duplicated Trask's DNA so she could also issue orders to the Sentinels, programmed to obey only those with the DNA of a Trask. Cassandra infected her own body with millions of nanosentinels just as she was captured by Cyclops and Wolverine.
Cassandra was taken to the X-Mansion, where she broke free and defeated most of the X-Men easily. Cassandra then put herself into Xavier's machine Cerebra (an enhanced version of Cerebro) and switched minds with her brother before Emma Frost snapped Cassandra's neck (Emma had been in Genosha teaching during the attack and witnessed her students massacred). Trapped in Cassandra's broken body, Xavier was unable to warn the X-Men before Cassandra, now in Xavier's body, shot him.
Possessing Charles and Killing the EvidenceImperial
Now in Xavier's body, Cassandra mentally forced the Xavier Institute student Beak to beat Beast into a coma after he discovered that Xavier and Cassandra shared the same DNA. Cassandra Nova then contacted the Shi'ar, whose leader was Majestrix Lilandra, Xavier's lover. Cassandra manipulated the Shi'ar Imperium, driving Lilandra insane and using her to make the Shi'ar Imperial fleet destroy the empire. Cassandra also made Lilandra send the Shi'ar Imperial Guard to wipe out the mutant population of Earth, starting with the X-Men. The Guard fought the X-Men until they were able to show the truth to the Imperial Guard.
Angered at Cassandra's treachery and realizing the danger she posed, the Imperial Guard fought Cassandra, who defeated them and headed into the mansion. She had planned on using Cerebra to eliminate all mutants. However, Jean Grey (who was becoming increasingly powerful due to a manifestation of the Phoenix entity) was able to split Xavier's consciousness into pieces and store a little part of him in every single living mutant mind. When Cassandra used Cerebra and focused on all the mutants, the pieces of Xavier's mind were brought back together; at the same time, Jean Grey telepathically attacked the Immensity, successfully defeating her, and forcing Cassandra out of Xavier's body.
Without a body, Cassandra became pure psychic energy, bodiless and blind. Emma Frost tricked Cassandra into returning to what appeared to be her old body, which was in reality the alien polymorph " Stuff."
Cassandra's essence entered the body and was locked into a self-repeating program in the synthetic brain.
With the "Hellfire Club"
Hellfire Club
Cassandra, back in her original form, returned in the "Danger" story arc of Astonishing X-Men, alongside Sebastian Shaw of the Hellfire Club. During this arc it was implied that Frost's survival of the destruction of Genosha in New X-Men #115 was due to Cassandra Nova catalyzing Frost's secondary mutation. In exchange, Emma was to assist Nova as part of a scheme to infiltrate the X-Men as a sleeper agent (Nova having erased the memory of their encounter at the time). However, it has yet to be stated whether this was real or a false memory implanted by Nova.This infiltration occurred when Emma tricked Cassandra into entering what appeared to be her original body: Cassandra managed to plant a seed of her consciousness into Emma's brain. She then played up on Emma's survivor guilt over not perishing during the Genosha massacre and also her general guilt over her past life as the villainous White Queen in the Hellfire Club. Cassandra's influence resulted in Emma creating manifestations of Cassandra in her human form, Sebastian Shaw, Emma's younger self as the White Queen (calling herself "Perfection"), and Negasonic Teenage Warhead, a former student of Emma's who was killed in Genosha. Emma and these manifestations then proceeded to attack the X-Men; Beast was reduced to a feral animal, Wolverine regressed to a his past James Howlett identity as a timid child, Kitty lost control of her phasing ability, and Cyclops lost the use of his powers and was rendered catatonic.
Meanwhile, Emma/Cassandra subjected Kitty Pryde to a cruel dystopic vision that tricked her into using her phasing powers to open the containment chamber where Cassandra, trapped in Stuff's form, had been imprisoned. Afterward, Kitty was to murder Frost and the rest of the X-Men, as Nova's permanent host. Cassandra's plans were foiled by a revived Cyclops, and other students at the Xavier Institute (including Blindfold and Hisako Ichiki). Cyclops revealed that while "Cassandra" had influenced Emma to recruit Kitty to free her from the container, Emma had actually recruited Kitty to the team to kill her in the hopes that this would thwart Cassandra's plans. Admitting that Kitty was too much of a challenge to possess, Cassandra then attempted to have Emma transfer her mind into Hisako. While Cassandra was attempting to manipulate Emma on the astral plane, Scott was talking to Emma in the physical world, trying to convince her to return Cassandra's mind to Stuff. Emma's only response was to say "Go to hell.", though it is unclear whether she was talking to Scott or Cassandra. It is as yet unknown if Cassandra's possession of Hisako was successful, or if Emma returned her mind to its prison.
Powers & Abilities
Astral Form
Cassandra Nova is one of the mummudrai. They are incorporeal parasites, composed solely of emotional energy born from the astral plane of existence. The mummudrai are usually forced to fight with the mind of their host over a body. However, given the vast potential in Xavier's genome, Cassandra Nova was able to build her own body, mimicking human traits as best she can. Cassandra Nova has access the full spectrum of mutant functions in Xavier's genome (meaning she has the powers of Charles Xavier, the ones he could have and the ones he might receive as a result of latent mutation), granting herself vast psionic powers . These powers include telepathy, telekinesis and a phasing ability. She was able to block the considerable telepathic abilities of Charles Xavier, create psionic armor, forge battle armor from the materials around her, disintegrate the complete tissue of Wolverine's arm and make her body completely intangible to an extent that even allowed her to withstand a direct blast from Cyclops. 
She has all the powers of the "average" mummudrai as well, which are astral projection and mental possession. Her telepathic capabilities are so advanced that she was able to hide her possession of Charles Xavier's body over quite some time despite directly interacting with considerable telepaths like Jean Grey, Emma Frost and the Stepford Cuckoos at the same time. The mummudrai are able to copy the DNA of sentient beings and use it to construct physical bodies for themselves. The mummudrai can also manipulate the DNA it copies to act as a rapid healing factor or to phase through solid matter. Further, they can manipulate the DNA of others, breaking it down at the molecular level. First using her DNA copying ability, she mimicked Donald Trask III, a relative of Bolivar Trask, so that she can voice command the Sentinels, who obey the Trask family line, to attack Genosha. She said it took her ten hours to read and copy the three billion base letters of Donald's DNA sequence. Then she manipulated Emma Frost's DNA to express her secondary mutation.
Alternate Realities
Earth-15104 : Here Comes Tomorrow
In the Here Comes Tomorrow future timeline, Cassandra's reeducation was a complete success; she had embraced Xavier's dream and went on to become Headmistress of the Xavier Institute. Instead of simply going by the name of Cassandra Nova, she added the Xavier surname to her own, now calling herself Cassandra Nova Xavier. Alongside Wolverine, the three remaining Stepford Cuckoos (now calling themselves the Three-in-One), Beak's grandson Tito Jr, E.V.A. and No-Girl ( Martha Johansson), Cassandra became one of the X-Men, fighting against Sublime and its armies of Crawlers, led by Apollyon. Cassandra was destroyed by Sublime after it unleashed Phoenix on the X-Men.
However, this time-line diverged from Earth-616 when Jean Grey reached back and psychically forced Cyclops to accept Emma's offer to run the Xavier Institute together. In the current time-line, Cassandra remembered her original identity.
Cassandra factors prominently in the future depicted in X-Men: The End storyline (Book 3). In this timeline she remains a villain. She is primarily responsible for the Shi'ar attacks on the X-Men, which she had manipulated in the hopes of gaining control of Jean Grey and the Phoenix Force. Her hope was to bond with the Phoenix and thus be able to destroy all existence. Though she was successful, Jean and Psylocke are able to subdue Cassandra. Jean then tells Cassandra that they are all going to transcend reality. Jean uses her connection to the Phoenix to bring a host of X-Men together (both dead and living) so that they can all become one with the universe while bringing others back to Earth. Xavier and Cassandra admit that they are scared of each other, and Jean tells them that this is part of being human. Then, she and the resurrected X-Men form a giant Phoenix and become part of the universe itself.
Ernst Connection
It was hinted in Morrison's run that Cassandra Nova took on the form of Ernst once she was placed inside the body of Stuff as part of her reprogramming. The final hint was in Here Comes Tomorrow (New X-Men #153), where she tells Martha Johansson, who Ernst was always seen around, that "of course you can still call me Ernst."
Subsequent writers have tried to contradict this, under presumed editorial edict. Chuck Austen's New X-Men, Cyclops and Beast investigate Cassandra's containment unit following the destruction of the mansion, only to never find it (and seeming not to care once they don't); this would seem to suggest she was either not Ernst or they didn't know she was Ernst (Xorn, Ernst's own teacher, did not know but suspected Ernst was more than she seemed). Joss Whedon Astonishing X-Men apparently contradicts it by showing Cassandra Nova still in Stuff's form. Likewise, Ernst has been distinctly shown along side the student body in other publications. However, these attempts at retcons have not successfully ruled out yet the possibility that Ernst may very well be a derived part of Cassandra Nova.
