Had this one sitting around in my files, so I thought I'd post it today.

Two main antagonists from parodic(-ish) horror video games, who might seem all cute and innocent, but are actually more terrifying than what you would be let to be thought. Both are also the leaders of a group, can break the 4th wall, can warp reality in some way, and have some sort of meta powers, per-say (Flumpty's plot manipulation and Monika being able to control her game), which they use to mess around with their game (Though I already noted this for Monika).

Tbh don't really see this working as an actual fight, but I think it's an alright idea.
