~Jean Grey's Limitless Powers & Abilities~

Jean Grey-Summers is an Omega-level mutant, and has been one of the physical hosts of the vastly powerful Phoenix Force who possesses god-like powers and is one of the most feared beings that ever lived. With the Phoenix Force, Jean has potentially limitless psionic powers of telepathy, telekinesis, cosmic pyrokinesis and energy manipulation - Henry McCoy has said that, based on her massive power levels, "on the Richter scale, she'd be a 12". When bonded to the Phoenix, she is said to outclass mutants, granting her complete control over matter, energy, thought, and unlimited psionic energies. She can tap into reserved energies for future generations, denying them of existence.

Jean is considered to be one of the Earth's most powerful telepathic minds. Jean Grey, as the Phoenix, has limitless telepathic powers, able to influence any individual. Jean's telepathy allows her to communicate with others telepathically, read the thoughts of others, influence and control the minds of others, project her mind into the astral plane, and generate telepathic force blasts that can stun or kill others. Jean is one of the few telepaths skilled enough to communicate with animals (animals with high intelligence, such as dolphins,dogs, and ravens). She can also telepathically take away or control people's natural bodily functions and senses, such as sight, hearing, smell, taste, or even mutant powers. A side effect of her telepathy is that she is gifted with total recall - she remembers everything.

The Phoenix can revive, absorb, re-channel, and preserve the life-force of any kind of life-form, meaning that she can take life energy from one person and give it to others, heal herself with the same life energy, or even resurrect the dead, since the Phoenix is the sum of all life and death. As Phoenix, Jean's powers escalate to an incalculable level: allowing her to rearrange matter at a subatomic level, fly unaided through space, survive in any atmosphere, manipulate electromagnetic and cosmic energies for various effects and atmospheric disturbances. She has cosmic-level pyrokinesis, which allows her to create, control, and manipulate cosmic fire of extreme power. Note that her cosmic fire is not dependent on oxygen, which means that she can ignite it under seemingly impossible conditions such as the vacuum of space or underwater. Her cosmic pyrokinesis derives from her ability to generate intense heat

She manifests a "telekinetic sensitivity" (called "the Manifestation of the Phoenix") to objects in her immediate environment that lets her feel the texture of objects, their molecular patterns, feel when other objects come into contact with them, and probe them at a molecular level. She can also create stargates that can transport her to anywhere in the universe instantaneously. When she engages her Phoenix powers, Jean is surrounded in a flame-like energy corona that takes the form of a large bird of prey. As the Phoenix, Jean can resurrect herself after death and is unaffected by the passage of time. It should be noted that she isn't "borrowing" the powers of the Phoenix Force (as is perceived by some due to the fact that Jean was a host for the Force); Death itself has said that Jean is the rightful owner of those powers. Further evolution allowed her to actually become one with the Phoenix Force (as opposed to serving as its host) due to her status as an Omega-level mutant with unlimited potential.
