"Back on Krypton, no one was their own man. Growing up, I was taught that to accept help from people is not a shame, it's an honor."
"Your cousin never talks about Krypton."
"He was a baby when we left. But I remember it. All the time.
Kara Danvers and James Olsen[src]

Krypton was the home planet of the Kryptonians; before its destruction in 1979. It was located 2,000 light-years from Earth,[1] orbiting an old red dwarf star called Rao.


The planet was separated into guilds, two known ones being the science and military.[2] Krypton was governed by the Ruling Council, but its exact composition and functioning are unknown.

Apparently, birds didn't exist on Krypton.[3]

A flower native to Krypton was the Dar-Essa.[4]

Krypton had historic sites of the ancient ruins in Old Krypton, before the worship of Rao.[5]

Krypton's scientists designed probes powered by BetaHedrons, which contained information on the planet's culture, religion, technology, etc. These probes were sent out into space as a means of communication and so others could learn about Kryptonians' civilization.[6]



Kryptonian life began on Urrika, the planet's first continent. Urrika was inhabited by the Juru, a matriarchal tribal people with a polytheistic religion. Among their worshipped entities was Yuda Kal, a goddess of life and birth. Over time, the people's religion became monotheistic, with the sun god Rao becoming the only God. With the worship of Rao, modern Krypton was born.

Over time, the Juru's way of life became condemned due to its usage of dark magic. Eventually, the Ruling Council of Krypton ordered any evidence of the Juru, including their language and so-called "superstitions", to be destroyed and erased from their history.[5][7]

War with Daxam

Krypton is known to have feuded with its sister planet, Daxam, over their various differences, such as Democracy vs. Monarchy and how life should be lived. Both Krypton and Daxam went to war over their respective ideals, with casualties in the thousands.[8]

Dominator invasion

According to Kara Zor-El in episode Invasion!, at some point prior to 1966, Krypton faced an invasion by the Dominators. These hostile extraterrestrials killed many Kryptonians and even performed dangerous experiments on some.[9]


"Krypton's not just a place, it's a spirit. It's hope. It's sacrifice. It's what our parents did for us. What you did for Jonathan. We have made our parents proud by fighting for what's right. So, we have to keep fighting. And as long as that spirit is alive, Krypton will never die."
Kara Zor-El to Kal-El[src]

In 1979, the planet was known to be unstable, and would soon be destroyed. Amidst the chaos caused by the impending death of the world, members of the House of El chose to save who they could by sending them away from the planet. The infant Kal-El and his cousin, Kara Zor-El, were sent to Earth, with Kara instructed by her parents, Alura and Zor-El, to look after Kal-El. Shortly following their departure, the planet finally destabilized and exploded, destroying it utterly. The destruction of the planet released a shockwave that knocked Kara's pod off course and also sent radioactive pieces of the mineral kryptonite flying into space, some of which found its way to Earth.[1]

It was later discovered that Argo City survived the planet's destruction thanks to the efforts of Zor-El.[10] However, on December 10, 2019, it was destroyed in an antimatter wave, killing all, leaving Kal-El, his wife, Lois Lane, and their son, Jonathan, as the only survivors who later on evacuated to Earth-1 after that same wave destroyed Earth and the rest of Earth-38.[11] Argo was restored when the multiverse was recreated.[12]

    • It's implied that Krypton died in Earth-1's universe, and some kryptonite found its way to Earth since Oliver Queen has at least a few kryptonite arrows.[13][14]
