Just an idea I had

It'd be a small squad of characters against the player. Depending on the difficulty, the characters would be the following:
Uhm idk the difficulties but for now they'll be different only on Souls-like:
TVHead
The not better Hunter
Blue Cashier
Souls-like:
Shadow Soul
The World Master(I'll post him later)
Shadow Mage(i dont have an image of her lmao)

These guys would appear at the worst times and fight you before or after story battles.

so essentially theyre there to make you either super weak for boss fights or to make you have to redo the fight. that is the most evil thing ever and im all for it
