Jean Grey vs Superman

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.
