After Tritan went into space to fight a demon, he landed in a grey hole. Where as black holes erase matter, and white holes create matter, grey holes change matter. When Tritan arrived on the other side, he was no longer him self, as his arms were gone and his ribcage crashed entirely.
A few days later after floating in space in pain, he went into insanity and harnessed a sun. His missing arms gave way to a bunch of tentacles and he became effectively a sun-eater.
But that is not the full story. Through the hole, two beings emerged known as Peira Noid and Sheyna. While in the grey hole, DNA from the demon he was fighting not only managed to switch the gender of his alternate personalities, but also made both half-demon. The demon was destroyed, but still lives on as Eve, Sheyna's other personality.
Solarizeus has the powers of light. It is utterly effective against dark powers.
He also knows how to use fire as well.
