I used to write myself and my friends into silly stories and dump them on Facebook when Notes was a thing. I've written so many! One such example is What? I'm a Pokemon?! (which I've brought back and re-written). The general premise was that everyone had been pulled into this unnamed PMD universe and had no idea who they originally were except the two main characters. This also included characters from other franchises - Death Note, Slayers... the ones I can remember anyway (they were my two big obsessions at the time.)
I have a soft-spot for this story, so I've revived it a couple of times to share with others. The most recent re-write has removed this cross-over idea somewhat, although I still deliberately drop cameo hints to some of the background characters. For example Rollo is a new addition who is deliberately based off Anai from Aggretsuko, and Pika the guild master was always meant to be Liszt from Ookami San and her Seven Companions (with a bit of PMD's Wigglytuff thrown in for good measure). I managed to find the entire original story (unfinished 'cos I never completed it) in my Facebook notes and I will be harvesting some of the ideas from it to recycle. I'd forgotten so much! The new idea is a little less crack-fic and more comedy with drama. I will try to maintain some crack-fic elements though because the original was a crazy random mess. This is more apparent in the first two chapters of the re-write since they're the most loyal to the original idea.
I also found another Pokemon 'fic I wrote for my friends called Pokemon Cracked Version, but it is utter cringe and will remain forever hidden in my long-lost Facebook notes
Afterthought after proofing - Man I love using brackets huh...
