Which two powerful beings with seemingly no limits who can bring fear to both friends and enemies will emerge the victor?

Superman

Superhuman solar energy

Superman gets the majority of his powers from Earth's yellow star, effectively making him a giant solar battery; when he uses Super Flare he expels that stored up energy in the form of a giant blast.

Solar energy absorption and healing factor

Superman's powers rely on his cells' ability to absorb and metabolize solar energy from yellow stars like Earth's sun. His Kryptonian body is a living "solar battery" that absorbs solar energies and converts them to fuel for vast superhuman abilities that wouldn't otherwise be afforded under Rao, Krypton's red supergiant. His cells also store yellow sun energy so he can use his powers under objects, at night, in dark places, and in space.

Superman is shown, especially in recent comics, to possess remarkable recuperative powers that allow him to quickly heal from wounds and makes him immune to all forms of human or Earthly diseases, illnesses, viruses and toxins. Superman heals faster when he is closer to the sun and absorbing more solar rays.

Pre-Crisis, yellow stars were said to emit "ultra solar rays" which enabled Kryptonians' superpowers; penetrating the Earth itself, said rays also enabled Kryptonians to stay super-powered at night.
Post-Crisis, it is the overall high intensity of yellow solar radiation, versus the far weaker red solar radiation of Krypton's sun, that is shown as causing Kryptonians' superpowers. The more yellow sun rays Superman absorbs the stronger he gets; in some instances he has been shown to enter the sun in order to increase his powers to their highest potentials, as seen in 1998's DC One Million storyline. Superman can also absorb solar energies of other class stars such as white stars and also when he absorbed the solar energies of a blue star that increased his abilities to a higher degree and gave him additional abilities. The light of dwarf stars, pulsars, and quasars also grants Superman different abilities. However, he cannot gain enhanced abilities from the energy of red stars; various reasons have been given for this. When Superman visited Olympus, where he and Apollo got into a fight, Apollo struck Superman with a sun beam, making Superman stronger and feeling like he "drank a bucket of adrenaline."

Solar flare and heat vision

Superman's heat vision is the ability to emit solar energy from his eyes. This usually resembles bright red or orange laser-like beams, which may be invisible at low temperatures but extremely bright at high ones. The effective range of his beams is at least hundreds of feet. It can also reach hundreds of miles wide. In addition to varying the beam width, height, and intensity, Superman has demonstrated a high degree of skill and accuracy in manipulating his beam, being able to use this power with surgical precision and at microscopic levels. Superman can lobotomize or excise someone's psionic powers as shown in The Elite when he cut off Manchester Black's powers. Since the power can be used invisibly, Superman often takes advantage of that to perform tasks subtly without needing to get into costume. In some versions, these beams can also be used to rapidly expand air or other matter to produce great concussive force. The beams are tremendously powerful, and can be used to rupture steel plates and pulverize rock. Also in some stories, it can be reflected like a true laser. Superman can do this with great skill and accuracy, manipulating the blasts to strike multiple targets in rapid succession, or more mundanely to remove his very durable facial hair. In the Post-Crisis stories, Superman has the ability to destroy entire planets with his heat vision with minimal effort. However, it is sometimes shown to be one of his more physically draining powers to use, as it uses such concentrated solar energy. In the Pre-Crisis stories, Clark wears glasses with lenses made of Kryptonian glass (initially salvaged from his rocket ship's transparency dome) so he can fire his heat vision through them without damaging them. In the stories from the 1986 relaunch onward, Clark wears glasses with regular lenses, which force Clark to momentarily lift them out of his eyes' firing arc to use his heat vision effectively. In revision in Superman: Secret Origin, Clark wears glasses with Kryptonian glass that are intended to contain unwanted firings. Heat vision was initially introduced as "the heat of his x-ray vision" (a byproduct of his existing x-ray vision powers) in Superman (vol. 1) #59 (July 1949); heat vision as a separate power first appeared in Action Comics #275 (April 1961). In Superman #38, part of The New 52, it is revealed that Superman's heat vision is a precursor to a power called "super flare". This power utilizes all the solar energy stored within Superman's cells, allowing him to resort to an all-out attack. However, Superman cannot use it more than occasionally, as it drains him of all the solar energy he has stored up until he can recharge his cells with solar energy which takes him about 24 hours. During this time frame, he is essentially human in his abilities.

Superlongevity

In different levels varying between storylines, Superman is known to have an extremely long life span and much slower aging process, even potentially ageless. Staying inside a star for about 15000 years stopped his aging process, as seen in one DC One Million storyline.

Solar invulnerability

Immunity to almost all forms of harm and ailments, including extreme force and extremely high temperatures. Effectiveness has ranged from nothing less than a "bursting shell" being able to pierce his skin (in the beginning of the mythos), to being completely unharmed by a star going supernova, to withstanding the collapse of universes. Explanations for this ability have ranged from Kryptonians having a molecular structure with a density superior to that of titanium and having strong bonds within the cells of his body that cannot be pulled apart. His invulnerability has enabled him to withstand Darkseid's omega beams, a feat originally thought to be impossible. In the rare instances, however, that Superman has required medical attention, this resistance to injuries has complicated necessary procedures such as surgery. For instance, when a criminal shot him with a kryptonite bullet, a surgeon was forced to give Superman a controlled exposure to the mineral, thereby temporarily weakening his skin enough to make the incisions necessary to remove internal fragments of the bullet.

Superman can also withstand kryptonite in certain circumstances, but prolonged exposure will eventually be fatal. Superman's invulnerability is further increased by his bio-electric aura, which protects him from some attacks and can be extended to protect others like in All Star Superman. In some versions, this power greatly retards his aging and increases as he gets older, sometimes rendering him effectively immortal. The epilogue to the Justice Society of America storyline "Thy Kingdom Come" (a sequel of sorts to the Kingdom Come limited series) showing Superman surviving 1,000 years into the future, albeit as a very elderly, hunched-over man. Another version in DC One Million lives through the 853rd Century, some 83,200 years from now, though he was living inside the sun for thousands of years before coming out, making him godlike in his abilities. Superman is frequently depicted as being virtually indestructible, however his solar aura will drain away if he takes too much damage. Normally this isn't an issue since exposure to sunlight will instantly refuel the aura, but as seen with his duel against Doomsday, if Superman is out of sunlight for too long his defensive abilities will deteriorate.

Flight

Because Earth and the Sun exhibits less gravitational pull than that of Krypton, and also due to his solar-powered body, the Man of Steel can also alter his personal mono-directional gravity field to propel himself through the air at will. Originally, he only had the power to jump great distances, as stated by the 1940s Superman cartoons slogan "Able to leap tall buildings in a single bound." This was also shown in the movie Man of Steel. His power of flight has ranged from simply being able to jump great distances using his vast strength, to beginning in late 1941 being able to accelerate, float in midair, and change direction while traveling. Later he became able to traverse interstellar distances without stopping. Lex Luthor once theorized that Superman had to have originated from a gigantic planet with such enormous gravity (capable of literally crushing a normal Earthman to death in seconds) that his species had developed natural anti-gravity organs just to be able to function under normal conditions; on Earth, this would allow him to control his own gravimetric field in order to fly, due to the lesser gravity of the planet as well as his solar-powered body.

Strength

Enhanced physical strength far above that of a human and even most super-humans, making him "more powerful than a locomotive," is one of Superman's signature powers and has often been described as chief among his other abilities. Depictions of the upper limit of how much weight he can lift have ranged from being able to do the work of several laborers in half the time, crush diamonds in his grasp, lift objects hundreds of times his own weight including any sized vehicle over his head, bend steel with his bare hands, lifting mountains, and all the way up to in the Silver Age and Modern Age where he is seen moving entire planets. This makes him one of the strongest beings in the DC Universe. After being saturated with yellow solar energy in All-Star Superman, his strength was tested, and demonstrated to be sufficient to support over 200 quintillion tons (or 2x1020 tons in scientific notation, i.e., two hundred billion billion tons); he held this much with one hand and he even said he feels like he can pick up more, enough to pull Earth away from the sun. As of The New 52 reboot, his strength now exceeds 5.972 sextillion metric tons, and he managed to do it in the absence of a sun for five consecutive days with only a few drops of sweat, leaving Superman asking for more, although this has been done before by the New Earth/Infinite Crisis Superman, when he moved the Earth away from the Sun against Starbreaker's force. On this occasion, he did have the assistance of the Green Lantern, however, it should be noted that Green Lantern only made a chain out of willpower and connected it to Earth, with Superman alone providing the actual pulling strength. Explanations include being adapted to the heavier gravity of Krypton, and his muscles using the power of the solar energy which fuels all his abilities. While in direct yellow sunlight, his strength can be augmented to incalculable and limitless levels. He has strength necessary to shatter entire worlds. Superman's stamina has also been shown as limitless while he remains in yellow sunlight. DC Comics is not known to have coined a similar reference to Marvel Comics's reference, “Class 100 strength,” to Marvel characters whose super-humanoid strength levels are so high that they can lift (press) 100 tons or more for extended periods. It is possible that Superman's powers have no upper bound as long as there are stars or star like objects. He has also lifted the embodiment of Spectre known to be of infinite mass with the aid of Wonder Woman and Green Lantern, and he held a black hole with his bare hands alone. Unhealthy exposure to yellow or blue solar radiation can increase Superman's overall strength. However, despite his limitless strength under the radiation of a yellow or blue star, Superman has sometimes been overpowered and has even been beaten to death as his present strength is dependent on his intake of solar energy.

Kinetic energy explosion

In Action #49 of The New 52, Superman became able to harness the kinetic energy his body generates and focus it into his blows. While doing this and upon contact with a target, he can release the energy in the form of a concentrated explosion, decimating his target and thereby making his strikes all the more potent.

Superhuman speed and reflexes

Another one of Superman's signature abilities is his superhuman speed, allowing him to move, react, run and fly faster than the human eye can perceive. It was originally—and famously—classified as being "faster than a speeding bullet," allowing him to catch bullets in mid-air before they hit him, or anyone else. His top speeds have ranged from nearly a hundred miles per hour when he was first created in the 1930s to those surpassing the speed of light. His thoughts, perceptions and reflexes are also accelerated to be able to control his actions while moving at high speeds and being able to perceive the world in slow-motion. Superman's running speed has often been shown to be on par with that of The Flash's. (DC Comics even published a "limited collector's edition" titled Superman Vs. The Flash in the 1970s, whose content it promoted as "The Greatest Race Of All Time!" The two actual stories told within it reprinted a Superman story titled "Superman's Race With The Flash" and a story about The Flash titled "The Race To The End Of The Universe" that also involved the entire Justice League of America. Both races ended in dead heats.) Wally West said he was initially slower than Superman until overcoming his anxiety over succeeding Barry Allen and fully mastering the speed force. He describes Superman as running over two thousand miles per second.[18] In Superman: Red Son he claimed to be able to move faster than ten times the speed of thought.

Superhuman intelligence

Superman is often shown to have a flawless, eidetic memory of everything he has ever seen, read, heard, or otherwise experienced. In most portrayals, Superman is capable of multilingualism and is able to learn, speak and understand any language he comes in contact with. Superman possesses intellect that surpasses genius-level. People from Krypton already had genius-level intellect, being a society thousands of years ahead of Earth in technology. In the presence of a yellow sun, Superman's intelligence is further enhanced, literally to super-humanoid levels, giving him super intelligence and allowing his brain to operate faster than a supercomputer.[19] His intelligence has enabled him to create effective strategies and tactics when engaging enemies during situations from which his powers alone cannot save him.

Martial arts

While most authors prefer to portray him as a brawler in combat, relying more on the magnitude of his powers for victory rather than any real martial prowess, there have been some exceptions. Many stories depict Superman as a very capable Master Combatant with or without his abilities, as he has been trained by both Wildcat in boxing and Mongul in the fighting arts. He has fought and learned from Wonder Woman and has also learned martial arts techniques from Batman. To a lesser degree, Superman is also adept at armed combat, as he is shown to be decent with a sword and hammer. He has also learned two different types of Kryptonian fighting styles, Torquasm-Rao and Torquasm-Vo to enhance his body and mind. Initially, the New 52 saw Superman's return to being an untrained combatant, with the likes of Captain Comet remarking that the Man of Steel's brawling skills are formidable in spite of this. However, this was soon rectified in the form of his receiving combat training from Wonder Woman.

Superhuman breath

The ability to inhale and exhale huge volumes of air with great force, capable of extinguishing large fires and moving heavy objects such as cars. Super-breath also allows Superman to hold his breath for extended periods in airless environments. In one 1970s-era Superman comic, he saved a town from a tornado by inhaling the twister into his lungs. He then flew just above Earth's atmosphere, with his chest looking somewhat distended, and exhaled the tornado into space. In another 1970s comic, Superman was inflicted with a condition whereby if he stepped in the ground or otherwise came in physical contact with the surface of the Earth, explosive energy orbs would begin to rise from the area immediately near him, endangering anyone nearby. When Superman realized he was causing the orbs to appear, he resolved always to remain in flight until he could find a solution to the problem. Since, however, as Clark Kent, he could not be seen flying, instead, Clark walked around constantly expelling a jet of air straight down from his nostrils to keep his body just millimeters from his walking surface. The release (exhalation) of highly compressed air through a valve (such as pursed lips) causes it to drop radically in temperature. This is known as the Joule–Thomson effect, and when Superman does this, it is usually referred to as Freeze Breath, Freezing Breath, Arctic Breath, or Ice Breath, and can cool almost anything to sub-zero temperatures and freeze air moisture solid, effectively creating ice.

Superhuman senses

X-Ray Vision – The ability to see through solid objects, usually with the exception of lead. Early stories assumed that hiding objects in lead would prevent him from finding them; however, more modern stories have Superman being able to take advantage of lead's x-ray opacity to do a wide scan of an area with his X-Ray vision in which the lead objects become immediately visible and then narrow his search to those specific locations. Explanations for how this power works vary, but rarely include the emission and perception of actual X-Rays, as such high-energy radiation would actually be dangerous to living things on which he uses it. Another theory involves being able to see and concentrate on the patterns of natural cosmic radiation as it reverberates off objects. X-Ray vision was first used by Superman in Action Comics #11 (April 1939), where it was called "Superman's X-ray eyesight."

Superhuman Hearing – Can hear far more sounds with far more detail and at far greater distances than normally humanly possible, including sounds on frequencies undetectable by humans such as dog whistles. Superman is able to mentally screen out most of these sounds to be able to function normally, even in a noisy environment, and can focus in on specific things, like a person's voice or heartbeat, even if they are in another part of the city. He can sometimes be shown to hear sounds on other planets, which makes it likely that his hearing is fundamentally different from that of a human, as sound cannot travel through the vacuum of space. Like humans and most animals, he is skilled at automatically noticing his own name out of the jumble of several overheard conversations, making him adept at quickly responding to calls of distress all over the city

Superhuman Vision – His senses grant him the ability to see farther and with greater accuracy and detail than humanly possible. Sometimes includes the ability to see EM frequencies invisible to humans, such as radio transmissions, infrared light, and the bioelectric aura which surrounds all living things, even in pitch-black darkness. Offshoots of this power include Telescopic Vision, which allows him to "zoom in" on far away objects, sometimes hundreds of miles away, and Microscopic Vision, which allows him to zoom in on objects that would normally be too small to see, like those on a cellular or molecular level.Superhuman Olfaction – A heightened and highly accurate sense of smell comparable to some animals such as dogs. Can be used to detect things like the chemicals in a bomb hidden somewhere in a crowded room. Not all versions of Superman display this power.

Vocal Abilities — Superman has shown possession of various vocal abilities. Stories have shown him being capable of raising his voice to loudspeaker levels, for purposes such as delivering a message to a large crowd.Early Golden Age stories showed Superman capable of mimicking the voice of others and throw his voice through simple ventriloquism.
By the 1950s, the said ability had evolved into a stand-alone power called "super-ventriloquism," the ability of Superman to send his voice across vast distances, but only to a specific person or place.

Super-ventriloquism was used in both Silver Age and Bronze Age stories, but it was generally discarded in post-Crisis stories.

Energy Awareness - In Action #49 of The New 52, after intentionally absorbing large amounts of Kryptonite in an attempt to destroy a damaged layer of skin cells that blocking his body from absorbing yellow solar radiation, Superman developed this power. With it Superman is able can detect and comprehend the very flow, consistency, and application of waves, signals, and transmissions throughout the world. This gives him access to new forms of information, including perceiving radio-waves and other such communications.

Superman Prime (One Million)

- Is arguably one of the most powerful versions of Superman to have ever existed (canon or not). He was so powerful, he was responsible for lending a portion of his fantastic powers to his descendants to utilize across the solar system to protect Human endeavors.

As to his connection to DC canon, the character appears in a what was dubbed "a possible future". The Justice Legion came back in time to the canon DC Universe to recruit the Justice League, so his canonical nature is deterministic at best. That possible future was erased with the previous DC Universe, so this version of Superman currently cannot exist under canon.

Superman Prime (Kal-El) left Earth after the death of Lois Lane and traveled the Universe for 700 years before returning to Earth. During his travels, he acquired vast abilities and skills from every being he met and gained perfection over all the abilities he received. He left the Earth defended by his descendant who was dubbed "Superman Secundus".

It is believed Kal-El broke through the Source Wall during his travels and training and studied under the Source itself, meaning he could have a portion of the Source's power or more, the true extent of abilities he received from the Source are unknown. (The Source is believed to be the originator of metahuman ability in the DC Universe and the center of the power of Jack Kirby's New Gods line of heroes.)

When he returned he forged a covenant with his descendants, he would bestow upon them a
small fraction of his power as long as they served for truth and justice. He also gained the abilities of his lineage and magnified them with his own power; ie. the Superman of the 67th Century married the queen of the 5th Dimension, GZNTPLZK, which in turn gave Superman Prime the abilities and powers of a 5th Dimension Imp. (See: Mr. Mxyzptlk) After the covenant he left and returned to his Fortress of Solitude in the center of the Super Sun."

Kal-El is the creator of the Superman Dynasty which protected Humanity in his absence. During is absence, the Superman Dynasty added to their powers by adding to their genetic heritage over the centuries. Superman Prime was still more powerful than they were, even after their genetic improvements.

Vast Energy Absorption Powers: Superman Prime remained in the Earth's sun for 15,000 years. It was theorized there was no upper limit to his powers at this point. Given his feats after only a few decades of living on Earth, this extended time "sun-dipping" increased his powers to a level that dwarfed his incredibly powerful descendant, Kal Kent, who was already more powerful than the gravitation pull of a collapsing star and capable of traveling faster than light. Kal Kent is considered the equal of the most powerful canon version of Superman known up to that time: The Superman of Earth-One.

Reality Alteration: Shown as capable, with the aid the Superman of the 5th dimension, of turning a fragment of DNA inside-out through time into a full-fledged human being with the soul of the original individual, presumably among other capabilities.

Power Bequeathment:Superman Prime is noted as being capable of sharing a portion of his power with his descendants, this fraction alone itself being a degree of power "far beyond any held by any metahumans ever" (though tying them inextricably to the Super-Sun that Prime inhabits as the source of their powers).

Immortality: Superman Prime has not visibly aged since the late 20th/early 21st century. It is this version of the character which gave rise to the idea that Superman might age slowly or not at all as long as he was exposed to solar radiation.

In addition: Superman Prime also had access to what is believed to be the last Green Lantern ring and had the capability of powering and using it.

Jean Grey

Omega-Level mutant abilities

(Phoenix and Dark Phoenix)

Jean Grey-Summers is one of the strongest and most powerful mutants who ever lived. She has great control over her infinitely powerful abilities, capable of manipulating the universe in her palm. After the Phoenix Force became one with its true heart and soul in the human form of Jean Grey, whose mind serves as a nexus point for all realities, Phoenix was able to tap into the vast powers from the sum of all life (the Phoenix Force); hence, her own abilities were augmented and magnified to God-like cosmic power-levels; and she became capable of controlling and wielding the boundless and unlimited powers of the Phoenix Force. She can create and control flames at will  as well as control and manipulate pure matter, energy, and thoughts completely. She also can resurrect herself after death. The Phoenix is able to generate cosmic flames which are not dependent on oxygen. Her fire and flames are created either through cosmic energy or by her ability to stimulate molecules which generates heat. Therefore, Phoenix can manifest fire independent of her environment even under seemingly impossible conditions such as underwater or in the vacuum of space.

Telepathy : She can manipulate and control the minds of others and even higher order animals within a vast, potentially limitless radius. Her notable powers include:

Telepathic Defense: She can manifest her telepathy in a number of defensive ways.

Telepathic Cloak: She can mask her presence and the use of her abilities from being detected by other psions and psychic entities. She can extend these defenses to others around her as well. Cloaking via telepathy is not perfect and powerful psis may notice and 'see' through this ability.

Cloak Mind: Ability to rearrange the “mental engrams” of mutants so their distinctive mutant thought patterns cannot be detected by Cerebro-type devises or by other telepaths.

Psionic Shield: Ability to erect a psychic shield for protection of herself and of others minds.

Telepathic Illusions: She can create realistic telepathic illusions and cause people to experience events which are not actually occurring.

Telepathic Camouflage: She can alter the apparent physical appearance of herself and other people by altering the perceptions of those around her. This can go so far as to make other people believe that the camouflaged people are not there (invisible). A limit, if one exists, is only imposed by the number of people she is trying to fool, not the number of people she is camouflaging.

Telepathic Manipulation: She can manipulate other people's minds easily, achieving a variety of effects.

Mind Control: She can control the thoughts and actions of others.

Mind Possession: She can possess the mind of another, and use that being's body as her own.

Personality Alteration: She can alter the minds of others by force of will, permanently changing their personality partially or entirely.

Mental Paralysis: She can induce temporary mental or physical paralysis.

Mental Amnesia: She can erase any awareness of particular memories or cause total amnesia.

Mind Transferal: She can transfer both her mind and powers into other host bodies if her own physical body could be somehow killed.

Induce Pain: Can also induce mental pain merely by touching the brow of her victim.

Heal Trauma: The ability to erase a person’s memories and to heal mental trauma through “psychic surgery,” the power to stimulate or deaden the pain and pleasure centers in a persons brain.

Mental Sedating: Can telepathically "sedate" her victims so that, if already rendered unconscious, they remain so for as long as she continues to "sedate" them.

Neural Jumpstart: She can increase the speed of neural signals in the brain, she could increase another mutants powers to incredible levels, but the effect was only temporary.

Dilate Power: Ability to place “psychic inhibitors” in the minds of mutant adversaries to prevent them from using their powers.

Mind Link: Ability to develop a mental link with any person which remains as a connection to that individual.

Psionic Blasts: She can project psionic force bolts which have no physical effects but which can affect a victim's mind so as to cause the victim pain or unconsciousness and turning someone brain-dead.

Astral Projection: She can project her astral form from her body onto astral planes or the physical planes. In the physical plane she can travel in astral form over vast distances. In the astral plane, she can mentally create psionic objects and manipulate the aspects of her environment. She can communicate with others astrally through her own will, or through contact with the thoughts and memories of others.

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

Psionic Firebird: She can manifest her telepathy as a psionic firebird; whose claws could inflict both physical and mental damage.

Telekinesis : telekinetic abilities enable her to levitate herself or other objects, propel or manipulate them however she wishes, stimulate individual molecules to create heat, and generate concussive force or protective shields.

It was later revealed that Phoenix had a secondary mutation. This mutation makes her the physical embodiment of the Phoenix Force; she and the Phoenix itself has stated that they are in fact one and the same being. The Phoenix powers are infinite. She is able to manipulate matter and energy on a sub-atomic scale, although there is substantial variation in the amount of power she has access to at any point based on her current health, mental blocks (natural or constructed - by herself or others), and sometimes for other more esoteric reasons.

Phoenix Force Avatar: A cosmic entity which embodies  creation and destruction, and derives its power from those yet unborn. Phoenix's body is permanently tied to the Phoenix Force as a nexus. Phoenix Force thinks of Jean Grey is its "host, body, and self." The Phoenix Force gives her vast psionic ability to manipulate time, space, matter, and energy for virtually any purpose. Phoenix (Jean) can also revive, absorb, re-channel and preserve any kind of life-form, since the Phoenix is the sum of all life-force. The Phoenix Force can significantly boost her mental abilities allowing her to rearrange matter at a molecular level, to fly unaided through space, create intense heat and thermal energy by stimulating molecular activity to create fire, flames, and concussive blasts. She can create fire under any condition, including while submerged, and she can manipulate thermal energy in her vicinity. She can also manipulate the voluntary and involuntary responses in the human body. She is also given the power to control the whole universe as "One-True Phoenix" which allows her to change the future of the universe with her infinite power.

Cosmic Pyrokinesis: After merging completely with the Phoenix Force, Jean is now able to create cosmic fire and flames at will, an ability known as Cosmic Pyrokinesis. Cosmic Pyrokinesis is the ability to create, control, and manipulate cosmic fire, fire which are not dependent on oxygen. The source of Phoenix's cosmic fire derives from her ability to manipulate matter at the atomic level, which allows her to generate intense heat, combustion and concussive blasts by stimulating heat molecules, or simply from her access to cosmic energy, or by combining both powers at once to create more powerful cosmic fire. When using this fire offensively, she burns her victims at the molecular and sub-molecular levels; thus no ashes or other combustive by-products are produced. Her cosmic fire is different from flames that are usually created by common pyrokinetics (like Sunfire or the Human Torch). Because her fire is not dependent on oxygen, she can create cosmic fire under seemingly impossible conditions like underwater or even in the vacuum of space. When using her Cosmic Pyrokinesis, the fire usually manifests in the shape of a large fiery bird, a Phoenix. Phoenix, however, has complete control over her cosmic fire and can shape them however she wishes; as a fireball, fiery claws, or even the appearance of an ordinary fire. The pain caused by this fire can be either mental, physical or both simultaneously. Although her cosmic fire (particularly when augmented by the Phoenix Force) is powerful enough to destroy entire galaxies, Phoenix's control over it is so complete that it only harms what she chooses to harm, which she calls it "burn away what doesn't work"; thus, her cosmic fire will burn her enemies until they die or she extinguishes it by her own will, and it has no effect on her clothing or anything around her vicinity.

Telekinetic Sensitivity: That lets her feel the texture of objects she has a telekinetic hold on, feel when other objects come into contact with them, and probe them at a molecular level to identify if they contain alien materials or feel when two things which she has a telekinetic “hold” upon are similarly composed.

Resurrection: Any time Jean dies, the Phoenix Force will ultimately resurrect her. Sometimes this resurrection is instantaneous, at other times she spends time in the White Hot Room doing "Phoenix Work". If she dies, the Phoenix Force will automatically create a telekinetic cocoon, known as a "Phoenix Egg". If she's in the Phoenix Egg, the "Egg" is very hot to the touch. She also can resurrect others from death, not just herself. This was shown in New X-Men when she resurrected Emma Frost from death, by reconstructing and repairing Emma's body on a molecular level. Furthermore, Emma's body had been obliterated while in diamond form, so Jean telekinetically merged her diamond body back together on a molecular level and then downloaded Beast's knowledge of human physiology in order to ensure that Emma's internal and external organs were placed in the correct place physiologically. It is still unknown how she resurrects somebody who has been dead for a while. Maybe she calls for the departed soul mentally while in the psionic firebird form, and takes them back from the realm of the dead after the departed soul realizes that she is calling out to them. Perhaps she captures the departed soul with the claws of the firebird and thus brings it back to the real world. In Phoenix Endsong, the Phoenix Force simply goes to the grave and enters Jean's rotting body. Afterwards, Jean's body is instantaneously healed and Jean simply is revived. Also, in Warsong, the Phoenix Force brings back the deceased Esme in a similar way. Bonding with the partly rotten body and simply healing it. Once healed, it is like Esme simply woke up from a dream state.

Pyro-Telekinesis: Jean is able to move objects by increasing the heat around the object using her fire, moving that object.

Abilities

Jean excels in astral combat. She maintained a psychic link to Cyclops for a number of years. She possessed the memories of the Phoenix duplicate of her as well as those of Madelyne Pryor-Summers, her clone, and is thus an expert pilot. Jean has shown some proficiency in hand-to-hand, non-psionic combat; the extent of this is unknown as she prefers to utilize her telekinesis and telepathy during battle. She has a college education from Metro College.

Strength level

Jean Grey possesses the normal human strength of a woman of her age, height and build who engages in moderate regular exercise.

Jean demonstrated the utmost limit of her telekinetic potency by grasping multiple components (the strewn rubble of a Genoshan school), which, according to Hank McCoy, weighed anywhere up to 50 tons. This is so far the heaviest load to be seen, without tapping into the phoenix persona. From this display it can be theorized that Jean Grey's maximum telekinetic load, without the use of the phoenix persona, is 50 tons and possibly above.

Jean Grey was said to be the Phoenix and the original Phoenix, She has 3 kinds of Phoenix: Normal Phoenix, Dark Phoenix and The White Phoenix of the Crown.

Though the White Phoenix of The Crown's powers were not fully stated but it was actually obvious that she is extremely an overpowered entity, million million times greater and more powerful than a combined multiverse's mutants and entities—more powerful than the beyonder.

Jean Grey's Normal Phoenix was an omega level mutant as well as her Dark Phoenix but when it goes to White Phoenix of the crown it is beyond any known level with a very limitless power, is also immune to an advanced reality-warping; can warp reality to an omniversal level. 
The One-Above-All admired Jean so much; furthermore, Jean/White Phoenix of The Crown is the second most powerful mutant in all the sum of the universes(omniverse).
Phoenix' existence will never be changed, it is created to be forever existed in the omniverse to balance life and death, the nexus of psionic energy.

The Phoenix heals a wounded Universe, Multiverse or even an Omniverse.
The White Phoenix of The Crown is forever existed in all realities, One-Above-All and The White Phoenix of The Crown guard and watch the Marvel Universe(OMNIVERSE).

The White Phoenix of The Crown is more powerful than Beyonder, Living Tribunal, Franklin Richards, Molecule Man and other beyond omega level mutant except the One-Above-All—all the beyonders except the One-Above-All are under White Phoenix.
