"I am Kal-El of Krypton. It is time to fulfill my destiny." – Kal-El, declaring his purpose to Martha Kent, Crusade

Kal-El is the native Kryptonian name of Clark Kent, the son of Jor-El and Lara, and he is Clark's Kryptonian persona following Jor-El reprogramming.

Physical Appearance



Kal-El has the appearance of his father. He has black hair and navy blue eyes, and his voice pitch is between a high voice and a deep voice. His hair is wilder and longer than Clark's.

Kal-El's basic clothing is with the color black; he wears a black buttoned t-shirt with a black belt, black jeans and black farmer boots.

Despite his articulate and fluent speech, Kal-El is cold, unfeeling and void of any emotions and attachments, as he has no memories or recollections of Clark's family and friends because of his reprogramming by Jor-El. He sees humanity as a weakness.

Kal-El is strongly driven to pursue his Kryptonian calling and hone the Stones of Power. He has some of Clark's latest memories before his assimilation into the wall, as he was able to remember both Jonathan Kent and his time in the wall, which he claimed "felt like home." He is curious and observing, and was able to tell that Lois talked too much.

It is also worth mentioning that Kal-El is more confident with his powers than Clark, which is possibly why he can fly and Clark couldn't at the time.

Season Three

Jor-El captured a human female named Lindsey Harrison and re-programmed her as a Kryptonian named "Kara" whose mission was to lure Clark to the Kawatche Caves so he could re-program him in order to force him to embrace his destiny. When Clark still defiantly refused, Jor-El threatened to kill Jonathan Kent if he didn't comply. Clark agreed to go with Jor-El in order to save Jonathan, leaving Jonathan in a coma.

Season Four

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.

After becoming aware of his whereabouts and mission, Kal-El set out to find the Stones of Power. Accepting his destiny, he used his powers to find the Crystal of Fire, but his quest was interrupted when Martha used black kryptonite to free Clark from Kal-El.

Powers and Abilities

Kal-El flight

Being completely rid and void of any ambition and focus on everything except to fulfill his destiny, Kal-El possesses powers that far dwarfs and overshadows Clark's at season four, to at least season seven.

  • Solar battery: Kal-El's abilities are nourished by the yellow sun. [citation needed]
    Kal-El power

    Kal-El overpowers Clark.

  • Super strength: Kal-El possesses boundless strength being excessively way more powerful than Clark. He tore off a plane door off its hinges with one hand.
  • Super speed: Kal-El can most likely reach speeds that Clark couldn't even dream of.
  • Flight: Kal-El can fly at insane velocities, able to reach altitudes that far exceed 20,000 feet.
  • Telekinesis: Kal-El can call Kryptonian objects to him.
  • Super stamina: Kal-El may not be able to tire under normal circumstances.
  • Super breathing: Kal-El could function in space.

Kal-El didn't demonstrate heat vision, X-ray vision, super hearing, super breath, Arctic breath, telescopic vision or micro vision, but he most likely could've used them perfectly if he wanted to.


Kal-El is most likely to have the same vulnerabilities as Clark and other Kryptonians, though he didn't display any.

  • Green kryptonite: Even though it was not shown, Kal-El was vulnerable to green kryptonite.
  • Blue kryptonite: Blue kryptonite can strip Kal-El of his abilities.
  • Black kryptonite: was able to restore the balance between Kal-El and Clark Kent.
  • Kryptonian dagger: A Kryptonian dagger can kill Kal-El.
  • Doomsday: Doomsday can simply and effortlessly slaughter Kal-El.


Kal means "child" and El means "star" in the Kryptonian language.[1] In Kryptonian dialect, the family name is spoken first and the given name next when the meaning of the name is expressed. Hence, Kal-El means "star child." The name was suggested to Lara by Kara while they were visiting the Kent Farm before the first meteor shower.

With the help of Dr. Virgil Swann, Clark learned that his birth name was "Kal-El." He has been referred to as "Kal-El" by Dr. Swann, Lionel Luthor, Jonathan Kent, Jor-El, Zor-El, Lara, Kara, the Disciples of Zod, Brainiac, General Zod, Raya, Bizarro, Baern, Titan, Martian Manhunter, Chloe Sullivan, Lana Lang, Lex Luthor, Faora, the Legion of Super-Heroes, Tess Mercer, Alia, Major Zod, Carter Hall and Lois Lane.

Clark has introduced himself as "Kal-El" to the Disciples of Zod, Lara, Martha Kent, Dax-Ur and Linda Danvers (the alternate universe version of his cousin Kara).


Dr. Swann: (reads the Kryptonian transmission) "This is Kal-El of Krypton, our infant son, our last hope. Please protect him and deliver him from evil."
