Dragon Ball AF (Motion Manga)

"It was rumored to stand for “After Future,” because the series took place 200 years after the end of GT. Others said it stood for “Alternate Future."

The earliest known record of the image purported to be "Super Saiyan 5 Goku" (drawn by David Montiel Franco) is the May 1999 issue of the Spanish magazine Hobby Consolas.

By October 2000, a specialized website called Majin.com posted the "Tablos" drawing as a new SSJ5 Goku, claiming that Dragon Ball AF was a real thing. On November of the same year, the website administrators apologized and said they were tricked by a con artist. After that, and since Majin.com was in English, the misinformation virialized all over the World Wide Web. In the end, a lot of fans—remarkably Toyotarō (then known as Toyble) and Young Jiji—based their own fan art and fan fiction on this fan-made rumor.

Though Super Saiyan 5, the Saiyan form shown in Dragon Ball AF, has not been seen in official Dragon Ball material, it is mentioned as a possible form by Bulma in the Dragon Ball GT episode, "The Heart of the Prince". Additionally, in Dragon Ball Xenoverse 2, after Mira absorbs Towa, his transformation resembles that of Super Saiyan 5.
In the Budokai and Budokai Tenkaichi video game series, the alternate costume for Gogeta in his Super Saiyan 4 form shares the silver hair characteristic with the fan-made Super Saiyan 5 form.

Goku's Perfected Ultra Instinct form from Dragon Ball Super shares the silver hair characteristic with the fan-made Super Saiyan 5 form.
Likely through pure coincidence, there is a mailbox with the letters "AF" on it in West City, as well as on a mailbox in Purple City.
