A legendary piece of Sailor Moon lost media has finally been found after twenty years. The complete seventeen-minute pilot for what is colloquially known as "Saban Moon" is now available to watch online. The show was set to be an Americanized adaptation of Sailor Moon with a combination of live-action acting and animated segments, but the pilot created by Toon Makers was never picked up for production.

For years the only evidence for its existence was various animation cells and a single music video for the show recorded with questionable quality that had been uploaded online. In part two of her The Western World Of Sailor Moon documentary, YouTuber Ray Mona detailed her search for the long-lost pilot and how she was able to finally find it in the Library of Congress. This is a particularly stunning find for fans of Sailor Moon as the series celebrates its 30th Anniversary this year.

"This was really hard to keep a secret," Ray Mona said in her video. "I mean, the whole thing had come as a shock to me as well, and frankly, my first time watching all of this it felt like some kind of surreal dream. So I tried my best to try and replicate that same feeling for people watching at home."

Through her efforts, she was also able to learn of various toy prototypes for the never-aired series that were produced by Bandai. While some toys eventually hit store shelves after the beloved DIC dub of Sailor Moon reached American audiences, there are still some that currently remain lost, but might still be in existence somewhere. With the full episode now revealed, fans were able to see the Toon Makers version of Tuxedo Mask and Queen Serenity for the first time as well since animation cells featuring the two characters have never surfaced online. The video containing the pilot in Ray Mona's video can be viewed below.

However, there are still mysteries that remain about the show. Ray Mona was unable to obtain the official script for the live-action portion of the show from the Library of Congress as it was, "misplaced in the facility and was unable to be recovered for the time being." Outside of her finds, there is also still a Making-Of video about the creation of the pilot, mentioned by Rocky Solotoff in an interview, that has yet to be found.

With the pilot itself now available to view, it remains to be seen if the search will continue in earnest to find these last lost bits of Toon Makers' Sailor Moon. There are still many secrets to potentially uncover for the series, like the Americanized names of the cast outside of Usagi would have been named Victoria. Still, it is an exciting time to check out the pilot and imagine what an alternate timeline Sailor Moon might have looked like in the United States.
