That's First Appearance. We use Origin. If we used First Appearance, New Hope would be it. But we use Origin, which says what media they originated from. If Vader were only in New Hope, then the Origin could be New Hope. But seeing as how he appears in six movies, various television shows, countless video games, books, and merchandise, his origin would be from the Star Wars franchise.
