Big Sonic 1: Basic idea

This was originally a big Sonic X Re:Zero fanfic idea, adding other ideas here that I felt were worth keeping. Ideas originally posted to Reddit by me(will update each new Fanfic recomendation thread), spoilers for stuff beyond S2 will be here, but after a warning that can be missed. I encourage people to use any and all of these ideas. Original description below:

This is my idea for a Re:Zero X Sonic the Hedgehog fic without any reincarnation or overpowered Subaru, just have him be a random civilian from the world of Sonic the Hedgehog, idea originally made for reddit. It is mostly a relatively detailed order of Sonic events from a random civilian's perspective after a bunch of tidbits about Sonic's world. I sprinkled in some ideas in here that include some spoilers up to the end of S2(Arc 4) of the Re:Zero anime without spoiler warnings, but try to put a warning right before anything that goes beyond what the anime covers(Arc 5+). I encourage you to use any ideas here for any fic you may have, including ones that aren't Re:Zero related, I have no plans to write this fic as of now. Spoilers to basically every piece of cannon Sonic media.
