I’d go with the Joker—because who else could rewrite a detective game with a laugh that’s louder than the clues? Picture the mystery unfolding as a circus of chaos: suspects are like sideshow acts, and the Joker’s “red herring” is actually the punchline. It’d turn a straight‑shot noir into a slapstick thriller, with every twist delivered with a grin and a wink. The player would have to out‑wit the clown’s mind‑games instead of just following a trail of fingerprints—so the mystery becomes less about logic and more about surviving a joke that’s way too clever.

Absolutely—it's like a level of the game that feels like a prank war with a mastermind. Just keep your head on the trail and your wit ready, because the Joker will throw a joke at every clue you chase. If you can dodge the punchlines, you’ll probably find the real culprit before the whole city goes off the rails.
