Kal-El

Kal-El is the one of the last survivors of his home planet, Krypton. Kal-El was soon sent to Earth alongside his cousin Kara Zor-El. He was then adopted by the Kents. In his adulthood, he moved to Metropolis and became Superman, and a founding member of the Justice League.

Early life
When his parents, Jor-El and Lara Lor-Van realized Krypton was on the verge of destruction, they put Kal-El in a pod and sent him to Earth, as Krypton exploded.

Kal crash landed in Smallville, Kansas, on the Kent farm, where he was adopted by Johnathan and Martha Kent.

At the age of 22, Clark moved to Metropolis, and became the world-famous superhero known as "Superman".

Personality
Clark is considered a "big blue boy scout" by those around him, even earning the nickname "Boyscout". He is willing to make whatever sacrifice a hero needs to make, and puts everyones lives before his own. He is very inspirational, which is hinted at numerous times. He welcomes people with open arms, no matter what.

Powers
Kryptonian Physiology: Superman possesses incredible superhuman abilities when exposed to yellow solar radiation: vast superhuman strength, speed, and stamina; invulnerability; flight; super breath; x-ray vision; telescopic and microscopic vision; freeze breath; heat vision; and super hearing. As a result, Superman is considered to be the most powerful member of the Justice League, something that many people, both allied and enemy, have admitted, since many of his key attributes and capabilities go beyond the extraordinary as pointed out by Wonder Woman.
 * Solar Energy Absorption: This is the main source of Superman's powers, his cells act as solar batteries that absorb different types of solar energy such as Earth's yellow sun, granting him vast superhuman abilities.
 * Superhuman Strength: Superman possesses incredible superhuman strength, allowing him to lift a truck and beat Parademons with it easily.
 * Flight: Superman has the ability to fly at high speeds by manipulating the graviton particles around his body allowing him to defy gravity.
 * Heat Vision: Superman has the ability to fire beams of intense heat from his eyes, capable of burning through steel, destroying and bore into Darkseid's eye sockets.
 * Superhuman Speed: Superman is capable of moving, reacting, running, and flying at near light-speed, though he limits his velocity on Earth to prevent environmental damage. While his reflexes aren't at the Flashs' level, Superman's natural mobility is able to just keep up with the speedster.
 * Nigh-Invulnerability: Superman is nearly indestructible, being able to take large amounts of damage without being injured. However, his invulnerability can be broken down by magic, or kryptonite. Sufficient enough physical strength can also harm him.
 * Accelerated Healing: Superman possesses a limited, but rapid healing factor which is further enhanced by his exposure to direct sunlight. Despite being fatally wounded by Doomsday, he survived and entered into a healing coma, where he slowly recovered from his grievous wounds. Upon being exposed to the sun's rays, all of the injuries he had sustained during his fight with Cyborg Superman had instantaneously healed.
 * X-Ray Vision: Superman has the ability to project harmless X-rays from his eyes, allowing him to see through solid objects with the exception of lead. He used this to see through Batman's smoke screen and look through Batman's mask to discover his identity.
 * Underwater Breathing: While his physiology appears human, Superman is able to breath and speak clearly underwater without any aid and can handle the bottom depths pressure of the ocean unfazed.
 * Superhuman Hearing: Superman's hearing is very sensitive, allowing him to detect even the faintest of sounds.

Abilities

 * Skilled Combatant: Superman is known to utilize hand to hand combat most of the time, as he uses his powers against his foes. During combat situations, Superman makes use of an improvised fighting style that relies on overwhelming force and speed.
 * Genius-Level Intellect: Superman's brain can process things at an extremely faster rate than normal human beings. His intelligence is also extremely high, possibly higher than the likes of Batman and Lex Luthor.

Weaknesses

 * Kryptonite: Superman is highly vulnerable to the radioactive crystalline substance known as Kryptonite. If he comes into contact or comes near it, he will be weakened, and nearly pass out. If the dose is high enough, it could kill him.
