Your main character already has time fart powers so the timey whimy junk is already plausible.
Wait sense the games are cannon to the show that means Kenny has interacted with the New Kid and knows about their Time Farts knowing time travel is possible
I’d really love to explore the future of South Park and what has happened to everyone and have a boss fight with Victor Chaos.
Haha, yeah a future South Park game with Butters as Victor Chaos would be hilarious! I can’t wait to see where the show and games go next.
