They've Taken Residence In My Mind And They Won't Quiet Down. - Tumblr Posts
Uhh

[May or may not have been writing a little something based off that... An AU where after he dies from Muscular Dystrophy. (The timeline is vastly different here. And cherry picking things that are and aren't canon)
Long story short, he essentially goes vengeful netherborn ghost on South Park. And since he's got eldritch blood (and I like the idea of him being stupidly overpowered) he essientally burns the town to the ground. Full on Godzilla levels of destruction.
Sprinkling in a bit of the memory alteration that after South Park is destroyed, any and all records and memory of the town are GONE. Mostly. People will have vivid nightmares of the event from time to time, and the ruins remain abandoned and forgotten. Even Kenny can't remember it very well. Like his mind (or his powers) are shielding him, trying to keep the burden of guilt from him.]
Since Kenny apparently has a ghost form do you think he's ever or could somehow wind up as a vengeful form of his ghost self? Ha like maybe sometimes the nature of how he last died just made him so angry his normally passive ghost self temporarily took the form of a poltergeist or some other variant of angry spirit ghost?
