My AUs (that were totally not made last minute just for plot)

A list of AUs that I totally didn't make up last minute to create some plot armor for my stories. ...okay maybe it was created last minute for plot armor, but that doesn't stop me from giving a full on explanation about each AU, with CHECKs. The CHECKs are only of the sans and papyrus if available, and a large and overly complicated description. There will also be very poorly made pictures, so bear with me. I will add pictures every now and then, but I'm mainly focusing on the info right now.
