At first I was going to defend FNAF, but I do agree. They are getting really annoying, telling you to change characters because you're also a (Insert Canon Character Here). Others that roleplay robots having feelings- I mean I KNOW there's children possessing the animatronics, but all of the hardcore shippers (Not the just for fun ones, the ones who hate you for not shipping Chica x Foxy) really put their RP soul into having that ship in the RP, always trying to make a pass at their muse's crush. And FNAF OCs... Some are good, some are 2edgy4me... And only half of the time do the canon characters accept your OC into their little pact.
All in all, Ficho is just really strange to me. It must be the fact that I LITERALLY LIVE IN BONFIRE. Also, don't forget about the Creepypasta OCs "____ the Killer","Subject ____", etc.
