I recently watched Superman/Batman: Apocalypse, and as noted in the question Does Superman have super powers outside of our solar system? Superman and Supergirl have all their powers on Apokolips. The answers pointed to the fact that Kryptonians get their powers from any yellow sun, can potentially store energy from our yellow sun when away, etc...

What I want to know is what color is the sun of Apokolips? It seems like there is a lot of explanation of why a Kryptonian might have powers there, implying that it's sun is not yellow. I am curious because it seemed that Supergirl was there for a while and I would have assumed that her powers would have faded by the time the Justice League arrived if the sun wasn't yellow.

  • I can't seem to find any definitive proof of the color of their sun, but in many Superman comics, Kryptonians only lose their power when exposed to a red sun (like the one on Kryton). Apokolips may not have had a yellow sun, but it stands to reason that if the color wasn't red, they would keep some symbolance of their power. Kryptonians are notoriously susceptible to radiation (as seen from Krytonite of different colors and from suns), and it could have been something along the lines of their sun was a different color, thus allowing Kryptonians to have only one super power at a time, or lessen

  • Their powers to where they could control them better. All in all, as long as the sun wasn't red like their home world, it wouldn't drain their powers. And, red suns don't drain them quickly, only over a large (it varies from comics and tv shows) amount of time.

  • Also worth noting is that in most cases where Supes loses his powers, it's not from exposure to a red sun, it's from being hammered by red solar radiation, typically in a weaponized form. If Kryptonians absorb solar energy based on what is closest, then as long as they aren't being beamed with red light, they may still retain their powers. All of that is theory of course.

1 Answer 1


There is no definitive evidence of the color of the sun of the Fourth World, the home of New Genesis and Apokolips. Since they are both in a completely different universe, one that is closer to the Source, there may be extenuating circumstances for Kryptonians maintaining their powers there since it has been implied the Source is at least partially responsible for metahuman abilities.


The Source can be considered the Consciousness of the DC Comics Universe, where it is the non-religious equivalent to Buddha-nature. It is the "source" of all that exists. Alternatively, it can be considered a description of the Creator God of the Universe, a science-fiction analogue based on Judaeo-Christian belief. Mostly associated with the New Gods, the Source was the supposed origin of the "god-wave" that is believed to have been responsible for creating and empowering the "Gods" of the DC Universe with their divine abilities. It also seems to be partially responsible for the ability of DC residents to develop super-powers, especially those which defy physics. (emphasis mine) --Wikipedia > The Source

In previous DC continuities, particularly in the Silver Age, Superman has visited both New Genesis and Apokolips and retained his powers sufficiently to operate in both places. However, the strongest beings of these realms rival Superman in physical abilities. Beings such as Orion and Big Barda have comparable superhuman strength and Darkseid's is considered even greater than Superman's under most conditions.

New Genesis, New Gods #1

On New Genesis, the sky is lit and blue, so there is a possibility of there being a yellow sun in the New star system shared by both planets. Given the polluted skies of Apokolips, the sun is never seen in any event.

Given this information, we are forced to make assumptions:

  • The star above New Genesis and Apokolips is not likely a red one, otherwise they would lose their powers slowly (and Kara would be of less interest to Darkseid as the potential leader of his Furies.)

  • Superman and Kara-Zor-El (in this Apocalypse DC Universe storyline) both store solar energy sufficient for them to maintain their abilities even thorough supreme exertion. Neither seem to lose a step in terms of their powers in their performance on Apokalips.


There was an Elseworlds graphic novel titled Superman, The Dark Side where Superman's was transported to Apokolips by Metron and whose powers did not develop on Apokolips. Darkseid created a battle armor which channeled the power of the Apokoliptian fire-pits to his Kryptonian body, giving him a semblance of his Kryptonian might. He later discards this armor on Earth, once exposed to yellow sun radiation.
