This is the tale much like other ones you have read. Where fan of a franchize goes to a con in near complete costume finds weird guy selling that last part of the persons costume and they get warped after buying the part to equestria as that being they have dressed as. I bet you have read stories where preson buys the final part to a costume and it is for the charecter of the opposit gender and the person has to deal with that mess. In my story I would kill just to walk on two legs reguardless of gender. No me being arugable the biggest yugioh fan on the planet went dressed as Naturia Exterio my favorite monster and after buying the last part I was missing I get which is the dragon armor helmet. I got warped to equestria after going against my instincs telling me not to I buy the part I need from a creepy sales guy dressed in my opion closely to the arms dealer in resident evil four.
