THERE IS NO SUCH THING AS DRAGONBALL AF.
Funimation have gone on record saying it won't happen. The gigantic Dragonball saga finally finished forever with the sixty-fourth and final episode of Dragonball GT.
Any writings or pictures you may have seen entitled "Dragonball AF" are nothing more than fan works. Don't assume just because a picture is surprisingly well-drawn or the fiction well-written that it is official. Not everybody is as useless with a pencil as you are. There are people out there with genuine artistic skills who enjoy doing fan art of Dragonball. There are people who like to dream about what might have happened next and devote their enormous creative energy into realising those dreams. Yeah, that Super Saiyan 10 Goku picture looks awesome. But it'll never happen. It's just wishful thinking.
And that's not counting all the excellent reasons there are not to make the series anyway.
Seriously though, Dragonball Z and GT should have been truncated after Frieza was defeated, like Toriyama originally intended. And then they should have scaled those 90-odd episodes down to a standard 26- or 13-episode arc like a normal anime show, which would be packed to gills with action, power, and plot twists. And brilliant.
In conclusion: There is no such thing as Dragonball AF.
