well, threre are many stories and drawings aabout DBAF (most of them fake) but i've heard a very cool story... it never mencioned new fusions and that kind of stuff... i like DBAF's art but only original ones (not those adapted ones that Maistro showed...
well the story i most liked goes like this...:
This goeas after GT when goku and the others decided that goku should fuse with the dragonballs, but these were full of evil again so goku, after a hard effort, got rid of the dragonballs, but this time, an Evil goku appeared... he destryed many cities adn a great battle occured... evil goku brought hell into the earth again and the Z warriors were getting beaten up, but when goku sees evil goku kill cold hearted a little baby, he goes berserk and transforms into ssj5, so he focuses a kamehameha in 1 hand and a genki dama in the other hand and then fires them at evil goku and wins the fight...
after a few days they decided to fuse goku with the dragonballs again (because now the evil power was gone) so goku went to another galaxie to test his power and he was so powerfull that he blew up that galaxie... so he decided to split his power in 2, the normal goku and goku san... goku san was good too but he hated goku because he was rejected by goku's friends... goku and goku san fought, but there was a tie... so they decided to train in diferent galaxies for some time and then return to earth to have their match again... when they returned, everything was very different, every1 has reached ssj4 level, vegeta recognized goku's power and said that he was no match fr goku... goku and goku san had their rematch in another planet and all the Z warriors went there too to see the match,but ,again, the result was a tie... when they returned to earth, it was being atacked by demons and the greatest of them all was in another planet... goku and goku san went to that planet while the Z warriors fought devils in earth... i don't remember this part well, but i know that there were 3 matches... 1 for goku, 1 for goku san and another for the 2 of them... they easily won the first 2 combats but the 3rd was very difficult and they were getting beaten up, so goku and goku san fused to have the "original power"... they defeated that devil and spared his life, but the devil atacked by the back, but goku with only 1 finger blocked the atack and killed him...
sorry, but i don't remember the ending...
