In BBTAG, the Persona characters themselves constantly mention outloud that they are so lucky that at least got stuck in a dimension that allows them to use their Personas/powers to fight.
In other verses, like the Xeno multi-franchise, stuff like Personas or non-corporeal strong wills are actually weak and inferior, because those belong to the lower domain and not the upper one, no matter what. Shulk and Pyra's inclusion in Smash ironically turned Joker from one of the most powerful, to one of the weakest fighters in Smash, because he's now stuck relying on lower domain entities and wills all around, never able to escape from the grasp of U-DO's existence, who is located in the upper domain.
The Persona lore is too incompatible to pair with a lot of IPs. Even Jojo I'm not sure if could work without making up weird writing excuses, because Stands don't need to rely so badly on cognitive palaces or shit like that to fight or use their powers. Stands get more free passes than Personas, unless some strong entity starts turnning the real physical world into a place affected by will and Personas.
