Cassandra Nova

Cassandra is able to duplicate the DNA of others physical beings and use that DNA to create a replica of that person and possess that created body so she can live in the body. She is also able to manipulate the DNA of others. She can manipulate the X-Gene in others so as to jumpstart their latent mutant powers. She can also move through solid matter and heal at an accelerated rate.

She also has the same telepathic abilities as Professor X.
