    Cassandra Nova is one of the mummudrai which 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 Charles Xavier's genome, Cassandra Nova was able to build her own body, by mimicking human traits as best she can. Cassandra Nova possesses telepathy comparable to Charles Xavier. After copying the DNA of Charles Xavier, Cassandra Nova has had accessed to the full spectrum of the latent mutant functions in his Charles Xavier (which means Cassandra Nova has all the powers of Charles Xavier, the ones he could have had and the ones he might receive, as a result of latent mutation), granting herself vast psionic powers. These powers include: telepathy, telekinesis, and the being able to release an astral form, which allows Cassandra Nova to focuses both her telepathy and telekinesis. Cassandra Nova is powerful to the point where she has defeated most of the X-Men easily, has beaten the Imperial Guard as well, and was able to break out of a gravitational bottle, which had been built to contain the Juggernaut. Cassandra Nova also has all the powers of the "average" mummudrai as well including:

    DNA Duplication/Shape-Shifting: Cassandra Nova is capable of copying the DNA of sentient beings and using it to construct physical bodies for herself. Cassandra Nova was able to build herself her own body, by mimicking human traits as best as she could. Cassandra Nova is also capable of accessing the full spectrum of latent mutant functions in one’s genome. Cassandra Nova was able to mimic the DNA of Donald Trask the third, a relative of Bolivar Trask, so that she could voice command the Sentinels, who would only obey the Trask family line, in order to attack Genosha. Cassandra Nova said it took her eight hours to read and copy the three billion base letters of Donald Trask's DNA sequence code.

    Biological DNA Manipulation: Cassandra Nova is able to manipulate the DNA of others, breaking it down at the molecular level. Cassandra Nova was able to manipulated Emma Frost's DNA to express her secondary mutation. Cassandra Nova has also stated to Emma Frost that she could strip her down to a single neuron without even blinking.

    Jumpstart/ Power Bestowal: After analyzing the DNA of another superhuman mutant, Cassandra Nova is able to selectively evolve their existing genetic traits as well as catalyze the untapped genetic potential of latent mutants. Once begun, the procedure is irreversible and can often result in unpredictable side effects.

    Phasing: Cassandra Nova can manipulate the DNA she copies to allow her to be capable of going through solid matter by passing her own atoms through the spaces between the atoms of the object through which she is moving though. In this way she and the object through which she is passing can temporarily merge without interacting, while each is not harmed when Cassandra Nova has finished passing through the object. This process is called “phasing.” When Cassandra is phasing her body becomes completely intangible to an extent that has allowed a direct energy blast from Cyclops to harmlessly pass right through her.

    Regenerative Healing Factor:Cassandra Nova can also manipulate the DNA she copies to act as a rapid healing factor. If injured, Cassandra Nova’s metabolism can allow her to rapidly regenerate and heal from large amounts of damaged or even destroyed bodily tissue hundreds of times faster and with more efficiency than a normal human regardless of the cause. Thanks to this superhumanly regenerative "healing factor," Cassandra Nova has been able to completely recover and heal from almost any injury of damaged and even destroyed bodily tissue which would have proved to be fatal to normal humans, including those with superhuman healing abilities. Cassandra Nova has survived from having her nick broken, has healed her severed vocal cords, regenerated brain cells, and Cassandra Nova has even fully regenerated organs such as her eyes or other large portions of her flesh including regenerating lost limbs, such as her feet and arms, which have been completely severed.

    Astral Form Projection: Like other mummudrai, Cassandra Nova is capable of releasing her astral form, through which she uses to focus her telepathy and telekinesis.

    Telepathy: Cassandra Nova is a powerful telepath comparable, possible even superior to Charles Xavier with vast psionic powers as she is capable of displaying various psionic feats with the minds of others including reading the minds of others as long as they don’t possess any kind of telepathic or psychic defenses and can project her thoughts into the minds of others within a long vast ranged distance that is a potentially limitless radius of herself and Cassandra Nova is one of the most powerful telepaths on the Earth. Cassandra Nova has been stated to be an Omega-Level Telepath by Psylocke and Cassandra Nova telepathic capabilities are so advanced that she has stated that she is more powerful than Emma Frost, Cassandra Nova was able to hide her possession of Charles Xavier's body for quite some time despite directly interacting with considerable telepaths such as Jean Grey, Emma Frost and the Stepford Cuckoos all at the same time. Cassandra Nova is powerful enough to use Cerebro, and she even tried to take over Charles Xavier‘s mind while he was using Cerebro. Cassandra Nova can use her telepathy in other way for different effects including, but not limited to:

    Telepathic Cloak: Cassandra Nova can mask her presence and the presence of others from being detected by other telepaths. Cassandra Nova’s abilities can at times go undetected or be counteracted by other more powerful telepaths depending on their power or level of skill in using their own psionic abilities. Cassandra Nova can extend these cloaks to other beings around her as well.

    Mind Control: Cassandra Nova is capable of controlling the minds of others upon mere concentration. Cassandra Nova was able to control Beak’s mind and force him to beat Beast into a coma with a baseball bat.

    Mind Possession: Cassandra Nova is capable of possessing the minds of another, and using that beings body as her own and once tried to take over Charles Xavier‘s mind while he was using Cerebra.

    Mind Alteration: Cassandra Nova is able to mentally alter the minds of others by force of will. Cassandra Nova was able to alter the minds of some of the X-Men in order to make Wolverine’s consciousness regressed to his past James Howlett identity as a timid 10 years old child, and reduced Beast’s consciousness to that of a primitive feral animal.

    Mental Detection: Cassandra Nova can sense the presence of another superhuman mutant within a small but as yet undefined radius of herself by perceiving the distinctive mental radiations emitted by such a being.

    Telepathic Illusions: Cassandra Nova is capable of creating realistic telepathic illusions which she can use to cause other people to experience events which are not actually occurring and project telepathic images. Cassandra Nova once was able to use realistic telepathic illusions to make Shadowcat believe she and Colossus were married and had a baby boy named Michael together who was taken by Charles Xavier in order to free herself.

    Mental Paralysis: Cassandra Nova is able to induce temporary mental or physical paralysis and Cassandra Nova was able to rendered Cyclops catatonic.

    Power Negation: Cassandra Nova can also mentally disable the powers of other mutants temporarily by preventing them from having access or control of their powers. Cassandra Nova was able to make Shadowcat lose control of her phasing ability, and Cyclops lost the use of his powers as well.

    Telepathic Camouflage: Cassandra Nova is capable of mentally masking herself, and the presence of other beings around her from being detected by telepathically altering the perceptions of others. Cassandra Nova can telepathically disguise himself and others, making her own appearance and those around her to be different to what other beings are seeing by either changing the appearance of clothing, or more involved disguises such as facial features and can even make herself seem to be invisible to that said person.

    Mental Amnesia: Cassandra Nova is capable of erasing any awareness of any particular memories or causing total amnesia in another person as Cassandra Nova was able to erase some of Emma Frost’s memories.

    Psionic Blasts: Cassandra Nova is capable of projecting psionic force bolts which although have no physical effects, but which can affect an individual’s mind so as to cause it’s victim intense pain or unconsciousness and even turning someone brain-dead.

    Psionic Shield: Cassandra Nova is able to erect powerful psychic shields for the protection of herself and the minds of others from any attempts that would mentally affect her mind or the minds of others including from such attempts as mentally reading, altering, controlling, or mentally harming her mind or others. Cassandra Nova was capable of blocking the considerable telepathic abilities of Charles Xavier.

    Post Hypnotic Implanted Seeds: Cassandra Nova is able to implant seed of her mind and consciousness into another’s allowing her to manipulate and somewhat control a person even if she is unable to have access of her powers. Cassandra Nova was able to implant a seed made up of her consciousness into Emma Frost’s mind after she was defeated allowing herplay up on Emma's survivor guilt over not perishing during the destruction of Genosha and also her general guilt over her past life as the villainous White Queen in the Hellfire Club in order make Emma Frost assist Cassandra Nova as part of a scheme to infiltrate the X-Men as a sleeper agent.

    Astral Projection: Cassandra Nova is capable of traveling through as a astral form onto either the astral planes or the physical planes of which she does not need to eat, drink, breathe, or sleep, due to being unrestricted by the physical laws which also makes her invisible, intangible, and makes her incapable of being harmed by anything less than very powerful psionic or telepathic attacks. In the physical plane Cassandra Nova can only travel in her astral form for over short distances. In the astral plane, Cassandra Nova can use her powers to mentally create psionic "ectoplasmic" objects and manipulate the aspects of her environment in the astral plane. While most telepaths are capable of staying in their astral form for up to 24 hours max before their physical body start to deteriorate. Cassandra Nova is capable of staying in her astral form for a longer amount of time due to her regenerative healing factor.

    Mind Transferal: Cassandra Nova is capable of transferring both her mind and powers into other host bodies if she wishes even if her own physical body would be somehow destroyed and Cassandra Nova once was even able to switch bodies with Charles Xavier through the help of Cerebra (an updated version of Cerebro) for quite some time while acting like Charles Xavier despite her directly interacting with considerable telepaths like Jean Grey, Emma Frost and the Stepford Cuckoos at the same time.

    Telekinesis: Cassandra Nova possesses powerful telekinetic abilities enabling her to manipulate living beings, inanimate objects, and even energy to some extent telekinetic. While it’s not fully known how powerful her telekinesis is, when captured by the X-Men, Cassandra Nova was able to break out of a gravitational bottle, which had been meant to contain the Juggernaut. Cassandra Nova can use her telekinesis in other way for different effects including, but not limited to:

    Levitation: Cassandra Nova can use her telekinesis to telekinetically levitate herself and others in mid air through the sheer force of her own force of will and move around at a speed at least over 10 miles per hour (16.0934 kilometres per hour) or hover and stay suspended in mid air at will, however it’s unknown if Cassandra Nova can truly fly or not.

    Telekinetic Force Fields: Cassandra Nova can use her telekinesis in more standard ways, such as creating powerful telekinetic force fields around herself in order to defend herself and other while repelling against incoming attacks including a missile attack.

    Concussive Blasts: Cassandra Nova can project her mental energy at a specific target, through which she can release devastating concussive force blasts of telekinetic energy powerful enough to disintegrate normal humans and has shown to be powerful enough to disintegrate the complete tissue of Wolverine's arm all the way down to the bone.

    Psionic Armor: Cassandra Nova has also shown that she can forge battle armor from the materials around her. While in Charles Xavier’s body she had constructed a psychic monster around herself, seemingly made up of the flailing body parts of all the people she had absorbed or controlled which she used to beat Gladiator.


    Education: Cassandra Nova has had various courses at the Xavier Institute.

    Genius-Level Intellect: Cassandra Nova has a genius level intellect and is an expert strategist capable of forming multiple plans even during combat as she seems to be a well educated woman, who is an expert in resist domination, the power of persuasion, strategy, manipulation, Biology and Genetics.

    Strength level

    Cassandra Nova possesses the normal physical human strength for a woman her age, height, and build who engages in minimal regular exercise. However, through telekinetic use, Cassandra Nova can lift much heavier amounts of weights.
