Despite the edgy name, he is simply a human turned into a black hole. His blood turns into crystallized jewels, and his body turns to wriggling red masses.
His existence starts creating anomalies across Earth, people turning into angels and anthropomorphs, human technology advancing heavily due to increase brain function, the earth expanding into a large planet with many continents and people who are trapped in their own earth sized bubbles. The become those familiar shows and worlds that people are stuck in.
After many years, he eventually grows tired and literally crashes out by destroying all life and making one world that he wants to play God and rebuild in his sight.
