>We know Egon Spengler was a real person

And from Scrapheap Shuffle we know a) that UF-Gryphon knew Spengler -- he mistakes Ido for Egon the first time they meet, and continues to call him "Egon" for the rest of the story -- and b) because he mistakes Ido for Egon, we know that it's the animated Ghostbusters which exist in the UFVerse -- because Ido looks nothing like Harold Ramis, and a whole lot like his animated counterpart.
