I saw another wiki where they called Supernatural "crap". Should we rename the Supernatural article to "crap"? No, because what people do on other wikis has no bearing on what is done here. Now, there's a difference between giving an unnamed character a descriptive name (like those unnamed demons) and a straight-up fan name to a named character (like what had happened here).
This is the standard naming pattern for all characters from alternate universes and alternate timelines. I don't see why this character should be any different.
