Yes there are many differences. In dragonball af, Broly is the seventh super saiyan that helped bring Goku back. But in dragonball zeron it was Trunks from the future.
After the Xicor saga DBZERON goes a different way than DBAF.
Dragonball Zeron is the manga sequel which is after the anime Dragonball GT. From the evidence I have seen it relates to the Japanese fan manga Dragonball AF. But there are a lot of differences. The only villians that are common in Dragonball AF and Dragonball Zeron are Xicor and Zeel. People talk about the Dragonball Zeron Manga which is going to be released in 2020.
There is no Dragonball AF
Dragonball AF (AprilFools) does not exist.
they are no episodes of dragonball af and af stads for "april fools"
No, anything Dragonball AF is fake.
DragonBall AF stands for April Fools
AF is Fan made. There is no Anime, just Photoshop Images of Dragonball AF.
Dragonball AF was originally an April Fools joke. There's fan made manga but nothing official.
There are no Dragonball AF novels because it is a fan made product
Dragonball AF is a non-existend and fanbased spin-off the Dragonball series. The statement that there would be a new series is based on a fanmade comic (manga) which was not made by the original makers. The original makers have stated, both in a conference and an article in Shounen Jump, that their will be no Dragonball AF. Simply said: Dragonball AF is fanfiction. Dragonball AF is not real.
They will not, ever. Dragonball AF isn't an original creation of Akira Toriyama. He has nothing to do with it. Dragonball AF is simply a creation of a fan of Dragonball.
There isn't Dragonball Af episodes because it isn't official yet.
