Sometimes I wish that Dragon Ball had better creepypastas, because I think there's some room for potential to explore these type of possibilities. I mean more like inverse shit rather than the usual "le spooky lost footage/video game with hyperrealistic blood oooo". The idea isn't really new but it would be interesting to see the perspective of someone trying to survive or witnessing someone like Cell or Goku Black creating chaos or explore different bad endings. I don't think anybody brought up Dragon Ball: The Others but that one also share what Grotesque Land Story had with evil variants of existing characters causing chaos against Goku and the others. There's some storytelling about the false beings too, and I like how it can vary since Goku's alternates are hostile while Broly's are docile. It even gave Piccolo more importance to me.
