What’s your fav fic idea, planned or written
In general: someone becoming a spectral. Bonus points if it's from a Near Death Experience since we haven't seen what that looks like in comic yet and not a lot of people have written what it could be! Personally I make it so there's a ghost outside the body but has a tether into the person's heart. If the tether breaks, that's it, the person is dead. The tether will fray slowly on its own and also slowly gain a color. Becoming a spectral through this method depends on how long the person was "dead" for and how much they remember being "dead", although there are outliers for both criteria.
Specifically: I'm not entirely sure! In terms of what makes me happiest when brainstorming ideas for it, I'd say that one of my AUs where Peekaboo and Forge are switched (so that Peekaboo is the one that possesses Johnny in Chapter 4) is always a hoot to think about, since it involves a lot of Peekaboo being very chaotic in a looney toons esque fashion and having a foil in Violet, who's trying to figure out what's up with him and make sense of this odd relationship she now has with both Johnny and Peekaboo. There's also fics I have planned exploring what interactions could happen with Stephen and Isaac, including a few where they kind of sort of become acquaintances. One such fic is in the works now!
