Capítulo 13: Persona 5 in different worlds

I recently came across two fanfics that have to do with Persona in some way. One only has one chapter, but the title is in DC with persona. The other has more chapters, and it's about the main character from persona 5 somehow ending up in the world of RWBY so far. It's pretty cool. So I thought, what if the persona 5 main character found himself in danmachi or other worlds like Marvel, or the whole team in persona 5 ends up being transported to a different world. It could also be a reincarnate story where someone wishes for or is given the abilities of the main character of persona 5 or a persona system. Either way, I feel both ways need a nerf. In some way, if the character has access to all the personas you can get in the game right off the bat, it would be to op, although I wouldn't mind it. I thought it would be more entertaining if the main character has to collect soul fragments or persona fragments that he collects from defeated or killed enemies used to create the persona or unlock the persona through the compendiumin the velvet room. For example, if the person is in the world of danmachi, he gets the fragments from killing monsters in the dungeon, stronger monsters, larger fragments, or beat an adventurer get some fragments as well, same thing stronger adventurer equals more fragments. So yeah, either just the main character of persona 5 in other worlds or take the whole group into other worlds I'm just thinking of the whole group who come speeding in while everyone is in Morgana while Futaba Sakura hacks into the avengers coms saying we're here to help during the battle of New York against Loki and everyone is just what the hell is going on and did that car just turn into a walking and talking cat, I think it would both be funny and cool all at once even while writing this and thinking about it I'm snickering from the idea
