"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 was born on the planet Krypton. Sometime before the planet was destroyed, he was sent to Earth, where later took on the moniker of Superman. Eventually Kal had a breakdown; which led to him becoming a threat to the entire world.


Kal-El meets the army.

Kal-El was born on the planet Krypton and sent to Earth following Krypton's destruction. At some point during his adulthood, he would become known as "Superman".[1]

Eventually he would become a threat to the population of Earth and along with a group of individuals, he used his heat vision to destroy several buildings in Metropolis and that night, he killed Lois Lane during a live interview.[2] Then, he killed a squadron of military soldiers led by General Sam Lane, with John Henry Irons as one of the soldiers.[3] When Irons was trying to escape using his ship, Kal-El tried to stop him.[4]


Similar to Kal's Earth-Prime doppelgänger, he was once a moral, honourable and just individual, who fought to protect citizens of Metropolis and overall the entire world; prior to his breakdown.

At some point, Kal had a breakdown; which led to him becoming a murderer and a tyrant, as he has no guilt shame or remorse for killing several innocent individuals in Metropolis; such as Lois Lane and Sam Lane.

Powers and abilities


Kal-El using his powers

  • 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.[3]
    • Flight: Kal is able to manipulate his own gravitational field to generate thrust and propel himself through the air.[3]
    • Heat vision: By concentrating the solar energy in Kal's body, he can emit red energy beams from his eyes.[3]
    • Invulnerability: Kal was able to withstand direct gunfire without taking any damage.[3]


"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.[3]
