Hajun's of Ragnarok

In a Moment of Boredom hajun from my other story (Hajun in the multiverse of madness) after remembering a manga from his human time, he decides to hold a tournament with the best fighters from various universes (animes, movies and books) that he knew and do they fight the gods he has chosen, to determine whether these universes should continue or be erased by the mad god HAJUN! All this just to kill your boredom.
