"He's not one of us, Sam. Where I come from, you're like me, and you don't trust him either because you know what he's capable of. You have to help me save your planet, Sam. Before Kal-El..."
John Henry Irons to Sam Lane about Superman's Earth-TUD22 counterpart[src]

Kal-El is the son of the late Jor-El and the brother of Tal-Rho. Sometime before Krypton was destroyed, he was sent to Earth, where later took on the moniker of Superman. Eventually Kal turned against humanity after meeting his brother, Tal-Rho.


Early life

Kal-El with his foster parents.

Kal-El was born on the planet Krypton and sent to Earth following Krypton's destruction.[1] On Earth, he was adopted by a family and lived on a farm. During a Fourth of July, his adoptive parents were killed in a car crash, with Kal being the sole survivor. Kal-El was placed in a foster home where he was mistreated by his foster parents and bullied by the other children. Eventually, his super-hearing developed, allowing him to hear his foster father beating his foster mother in the middle of the night. Kal confronted the man and accidentally killed him with his heat vision.

He fled the house but was arrested and taken to a special government facility where he was experimented on. Eventually, his super-strength had also awoken, allowing him to easily escape. While breaking out of the facility, he found the spaceship which brought him to Earth, and a sunstone crystal. Kal escaped to the Amazon, where he constructed a fortress using the crystal. At the fortress, he was trained by the A.I. of his late father Jor-El. Kal later became a vigilante known as Superman.[2]

Time as Superman

As Superman, Kal spent the next twenty years protecting Earth, winning the population's support. At some point, he thwarted a terrorist bombing of a federal building and captured a school shooter. Although he stopped many crimes, Kal grew frustrated as the worst of humanity still persisted, despite his efforts.[2]

Attacking Earth

Kal-El uses a nuclear bomb to destroy Coast City.

Kal was then approached by his brother, Tal-Rho. He promised Kal that they could cure Earth of its evilness if resurrecting Krypton through them. From there, Kal began attacking cities across the globe.[2]

Along with a group of individuals, Kal used his heat vision to destroy Metropolis, prompting major global resistance. That night, he killed Lois Lane during a live interview.[3] He also killed a squadron of military soldiers led by General Sam Lane, with John Henry Irons as one of the soldiers.[4] He also used a nuclear bomb to destroy Coast City.[2] On December 10, 2019, a wave of antimatter slowly began destroying the entire universe. As Irons was trying to escape using his ship, Kal tried to stop him. After Irons went through a wormhole to Earth-Prime,[5]

Battle on Earth-Prime

Kal was recruited by Magog to serve his needs.[2]

Kal-El was transported to Earth-Prime in 2049, where he battled Supergirl, but he was eventually defeated.[6]


Similar to Kal's Earth-Prime doppelgänger, he was once a moral, honorable, and just individual who fought to protect citizens of Metropolis and overall the entire world. However, due to his difficult upbringing and seeing the people of Earth not bettering themselves through his example, Kal eventually turned came to lose faith in humanity. This, combined with Tal-Rho's offering of a quicker solution, Kal came to betray humanity and began destroying the entire population.

Powers and abilities

  • Kryptonian physiology: Normally, like all Kryptonians, Kal-El's capabilities are no greater than a normal human of his physical conditioning. However, once charged by the energy spectrum of a yellow sun, he becomes able to perform various inhuman feats.[4]
    • Flight: Kal is able to manipulate his own gravitational field to generate thrust and propel himself through the air.[4]
    • Heat vision: By concentrating the solar energy in Kal's body, he can emit red energy beams from his eyes.[4]
    • Invulnerability: Kal was able to withstand direct gunfire without taking any damage.[4]


"The only remnants of your real home, Kryptonite, make you sick."
John Henry Irons, to Kal-El's Earth-Prime counterpart[src]
  • Kryptonite: Like all Kryptonians, even while empowered, Kal is vulnerable to the exposure of Kryptonite, a radioactive mineral from his home planet Krypton. Depending on the nature of the said Kryptonite, it will cause a different adverse effect on him.[1]
    • Green Kryptonite: Green Kryptonite not only physically hurts Kal, but also it weakens his physical attributes, making him equivalent to that of a normal human.[1]


  • Superman suit: Kal wore a black and silver protective suit as his alter-ego, Superman, to hide his identity from his enemies.[4]
