A question, Callie. Does this collaborative project still have to be some kind of spin-off, or otherwise something that wouldn't go on the Creepypasta Wiki? Because that would make things harder for everyone to agree on a single spin-off topic.
If the topic is open, though, I could always pull a few old dusties out of my big ol' hat of ideas. I wouldn't mind sacrificing one.
- God is a small child, his/her whims our reality; keep in mind that children are incredibly selfish and whimsical.
- Dice that decide a human's fate--life, death, suffering, etc. Think Death Note with dice, or maybe "tarot" dice.
- A "Missingno theory" about corrupted Pokémon (either actual corrupted data or something in-universe) turning into the glitch species encountered in-game. I only mention this because Pokémon is one of the few spin-off topics popular enough for the bulk of the community to collaborate on.
Sounds like a similar episode of The Twilight Zone. My concept of execution was a bit different in that the child would not necessarily be aware of his or her power, nor would those around it until interacting for an extended period.
