>>48030880First of all, I don't see what this has to do with anything, the name alicorn is irrelevant because pegacorns absolutely have been a thing since fucking forever. MLP didn't invent this shit.
Second of all, I could swear I read a long time ago that the word Alicorn WAS historically used to mean pegacorn, but that it was very rare. And the fandom found out about this and popularized the term. I have no proof of that tho it's just a memory.
