Goku in his AF form. AF was a fan created "sequel" to Dragon Ball GT. No episodes were made, rather, people just made concept art for it. It all started when a picture of SSJ5 Goku was passed around and was apparently official according to Toriyama. As it turns out it was done on April 1st. and well AF..stands for April Fools. So it was a hoax, but the characters are still around, and now are being immortalized into MUGEN. Enjoy!!
