Clark Kent

"He's everything you want him to be, and more."

- James Olsen to Kara Danvers describing Kal-El

Kal-El of Krypton is the son of Jor-El and Lara Van-El. After being rocketed to Earth as a baby, he was adpoted by a kindly couple in Kansas, who gave him the name of Clark Joseph Kent, and later grew to become Earth's mightiest superhero, Superman.

Arrival to Earth
Kal-El was rocketed to Earth alongside his cousin Kara Zor-El, from the doomed planet of Krypton. Making it to Earth safely, Kal-El was adopted by a kindly couple in Kansas, who named him Clark Joseph Kent, and while he grew up having a normal human life, later in his adulthood, he'd grow to become the superhero known as Superman. During his first heroic act, he saved a plane.

Finding a lost family member
Twenty four years later after Krypton's destruction, Kara's pod crash landed on Earth. Clark evnetually tracked the ship down and found his young cousin scared and alone inside of her ship. As he felt that Kara should learn how to be a human, and that she needed a family that could be with her at all times, he left her with the Danvers family, scientists who had helped him understand his own powers.

Meeting J'onn J'onzz
At some point, Clark had at least one encounter with J'onn J'onzz, whether or not this encounter ended up in a fight, it is still unknown, but it was enough for Clark to call J'onn, "the most powerful being on Earth".

Sending James to National City
He later asked James Olsen who he knew wanted to broaden his own horizons, to go to National City to keep an eye on Kara, and to deliver the blanket he was wrapped in as a baby, so she could use it as a cape.

Reactron
He arrives to save his cousin from Ben Krull after being called by James Olsen.

Myriad
Superman was arriving in National City to help Kara, but he was also affected by Myriad upon arrival to the amazement of Cat Grant.

Personality
Clark was described by James to Kara as "everything you want him to be, and more". According to James Olsen, he is very stubborn. Clark is protective of his cousin Kara Zor-El, as he asked James to keep an eye on her while he is off saving the world. As noted by Kara, Clark can be very independent to the point of refusing help.

According to James, Clark doesn't work with the Goverment because of their secret experiments on alien life, which has also caused him to distrust the Goverment itself. As an experienced superhero, Clark is confident, he has a sense of justice, honor and good morals.

Powers

 * Kryptonian Physiology: Like all Kryptonians, Clark possesses the power to absorb the light and radiation of stars, specifically those in the yellow spectrum. His body is constantly absorbing and storing energy from Earth's yellow sun, which in turn grants them incredible powers, such as superhuman strength, senses, impenetrable skin, and even the power to defy gravity.
 * Solar Battery: Clark is able to absorb solar energy from a yellow sun.
 * Super strength: According to Kara, Clark is "the most powerful man in the universe", a title that he may as well have earned due to his amazing level of physical strength, as he is capable of lifting well over 1,000,000 tons without any effort at all. Clark may as well be a fair level stronger than his cousin Kara, possibly due to his longer exposure to Solar Radiation.
 * Super speed: Clark possesses the ability to move at incredible super speeds, far greater than that of any normal human, essentially making him "faster than a speeding bullet". Superman once showcased his immense super-speed, to a level that Kara has yet to shown, when he arrived just in time to save her from being killed, more impressively, he flew all the way from Metropolis to National City in a matter of seconds. However, it is unknown if he is faster, or in the same league of speed as the Scarlet Speedster, Barry Allen, aka the Flash.
 * Flight: As all Kryptonians under a yellow sun, Superman is able to fly at tremendous supersonic-speeds by manipulating his own gravitational field.
 * Invulnerability: Clark is essentially invulnerable to all Earthling weapons, with bullets simply bouncing whenever they come in contact with his skin. He has also demonstrated to have more durability against damage than his cousin Kara, as he was able to resist Reactron's fully powered attack without even moving, whereas Kara was severly weakened with a single blast.
 * Accelerated healing factor: Clark is able to heal much faster than a normal human. Also, Clark's body processes and burns calories much more faster than any other normal human, essentially allowing him to eat all he wants without actually increasing in weight.
 * Super hearing: Clark has super-sensitive ears that can pick up sounds from miles away.
 * Super breath: Clark is able to exhale powerful gusts of air from his mouth. He can also cause the temperature of his breath to drop, therefore able to freeze nearly anything.
 * X-ray vision: Clark is able to see through all solid objects; except for lead.
 * Heat vision: By concentrating every solar-energy reserve he has on his body, Clark can emit powerful heat lasers from his eyes.
 * Immunity: Like all Kryptonians, Clark is immune to all forms of earthly diseases and illnesses.
 * Telepathic Immunity: Like all Kryptonians, Clark is immune to all forms of telepathy.
 * Immunity to Weight Gain: Clark can eat whatever he wants and not gain any weight.

Weaknesses
Clark possesses all the typical weaknesses of a super-powered Kryptonian.
 * Green Kryptonite: Like all Kryptonians, Clark is weak against green kryptonite, as it is a radioactive mineral from his home planet Krypton. Green Kryptonite not only weakens his physical attributes, leaving him vulnerable to weapons and anything in general that can kill a normal human, but if he is exposed to it for too long, it will kill him.
 * Red Kryptonite: Like all good Kryptonians, if Clark is exposed to red kryptonite, he will be left without morality, rationality, or any cares whatsoever. Left with only malice, pride and wrath, Clark will become malevolent and prone to hostility and aggression, making him a danger to everyone around him.
 * Lead: Clark can not see through lead, even with his X-ray vision.
 * Red sun energy: The energy from a red sun is known to be the Kryptonian's natural sun and therefore, exposure to it will make them the equivalent of a human on Earth.
 * Extreme energy: Extreme amounts of energy can be enough to kill Clark.
 * Solar energy depletion: Using his powers to its maximum for an extended period can significantly drain his solar energy to the point where Clark loses all of his powers and is rendered more human like for at least a day. This renders him as weak as a human, allowing Clark to get injured and killed as easy as killing a human.
