Kal-El

Kal-El is the Kryptonian birth-name of Clark Kent as well as his alternate personality after he was reconditioned by Jor-El. The son of esteemed scientists Jor-El and Lara, Kal-El was spared Krypton's fate by being rocketed to Earth as an infant in hopes of becoming a great hero.

Powers
His reprogramming by Jor-El didn't augment Kal-El's physiology in any way. As such, he still possessed all the abilities that Clark did at the time. Due to his psychological barriers being removed, Kal-El's abilities may very well have been considerably superior to his alter-ego.


 * Solar Battery: As a Kryptonian, Kal-El's abilities are rooted in his body's reaction to the yellow sun of Earth - his cells deriving nourishment and energy by metabolizing the radiation from the younger, stronger star. This endows him with momentum and overwhelming levels of strength and power.
 * Super-Strength: Kal-El wielded impressive super-strength - easily ripping off the pressurized door of Lex Luthor's jet with one hand. Without any of the doubt or humanity of Clark Kent, Kal-El was willing to use the full measure of his might. In his last moments, he single-handedly choked Clark.
 * Super-Speed: Like his super-strength, Kal-El could have pushed his body to velocities surpassing what Clark was capable of at the time. While he didn't rely on his running speed, it was his flight speed that showcased his full power - reaching terminal velocities that broke the sound barrier.
 * Super-Breathing: Kal-El was able to seamlessly hold his breath and survive both while flying at over twenty thousand feet in the air as well as outside of Earth's atmosphere, all without showing any sign of breathlessness or discomfort over the span of several dozen minutes or even up to an hour.
 * Flight: While Clark at the time was held back by insecurity as well as various other psychological barriers, Jor-El wholly purged Kal-El of these weaknesses. Liberated as such, Kal-El could harness his energy to suspend gravity's pull on him at will - breaking through Earth's atmosphere and flying in the air for the 1st time.
 * Technopathy: This was exclusive to technology from the planet Krypton, as they were engineered to respond to Kryptonian DNA signatures. With this, Kal-El was able to summon the Crystal of Fire to him just by raising his hand, and later he interfaced the coding in the Kawatche Caves just by touch.

Weaknesses
As a Kryptonian, Kal-El possesses the same weaknesses as Clark Kent. He is susceptible to any variant of Kryptonite, is rendered powerless by the radiation of a red sun, and can be affected by arcane spells like any man. Kryptonian metals as well as powerful aliens can injure him.


 * Black Kryptonite: Of all the variants, black Kryptonite affects Kal-El in a particular way. As it purifies Kryptonians of the darker aspects of their personality, it can separate Kal-El's personality from Clark's - giving him control again, while also losing any additional powers Kal-El may wield.

Origins
Clark was born as Kal-El, the only son of Jor-El and Lara, on the planet Krypton. Kal-El was a few weeks old[24] when Krypton was about to be destroyed after his uncle Zor-El ignited Krypton's core and also due to General Zod's attempt to conquer its people, Jor-El placed Kal-El in a spaceship, to send him to a good family on the planet Earth where he visited years ago. Though Lara wondered if the people of Earth would accept and love him, Jor-El reassured her that the family he chose would be good to him. Kal-El came to Earth during the meteor shower which struck the community of Smallville, Kansas, on October 16, 1989.

He was sent from Krypton as an infant, but because of the distance from Earth, Kal-El appeared to be between the ages of two and three when his ship crash-landed. Jonathan and Martha Kent found him in Miller's Field: unable to have children themselves, the Kents adopted the young orphan and raised him as their son. Because he owed a favor from Lionel Luthor, Jonathan allowed him to produce forged paperwork that made it official. They arbitrarily picked a May 13, 1987 birth date for their new son and named him Clark, Martha's maiden name.

Season 3
During the 1989 meteor shower, Jor-El saved a teenage girl named Lindsey Harrison after her mother's car was struck by a meteor. Sealing her inside the Kawatche Caves, he transformed her into a Kryptonian vessel - giving her new memories, Kryptonian-like abilities, and longevity.

Emerging from the caves sixteen years later, Lindsey - with no memory of her former life - made her way to the Kents' property where she introduced herself as Kara from Krypton, claiming to have come to recollect Clark as punishment for Jonathan breaking his covenant with Jor-El.

Eventually, Chloe learns "Kara's" true identity through fingerprint records. Jonathan confronts the two just as they are about to enter the cave wall. Jor-El seemingly destroys Lindsey - now useless - and begins strangling Jonathan, threatening to kill him if Clark doesn't enter.

Resigning to his fate, and hoping to spare his Earth father, Clark cooperates and begrudgingly enters the glowing fissure - disappearing into the cave wall. Inside the void, a naked Clark wakes up in a fetal position enclosed in energy, with Jor-El proclaiming he is to be reborn.

Season 4
Three months later, Clark returned, re-programmed as Kal-El of Krypton, a more obedient version of Clark who fully embraced his destiny. He was found in a cornfield by Lois Lane, where she took him to Smallville Medical Center. It was here that Martha Kent discovered Clark and volunteered to help him find a sign he was waiting for. Kal-El agreed to follow her, and the two returned to the Kent Farm.

Martha tried to jog his memories by showing him important parts of Clark Kent's life. When she showed him a picture of Jonathan Kent, he remembered him, and said that he's a dead man. Then, Kal remembered his Origins and Jor-El. Martha tried to convince him to give her her son back, but he pushed her out of the way. He then procided to break earths gravity laws, combining his Super Strength and Super leap to jump up into the air, high enough to give him a boost to fly for the 1st time.

Kal broke into Lex Luthor's Air Plane, and stole the Crystal of Fire. He then went down to the Kawatche Caves, but was inturupted by Martha Kent, who had Black Kryptonite. She then uses it to seperate Kal-El from Clark Kent.
