So this image http://image.noelshack.com/fichiers/2015/23/1433689455-emr07z.jpg is on the source section for Fusion Dance. I'm getting conflicting answers concerning this when searching the image. Some use it as fact while others say the image is fake, mutiple times from different sites. Can anyone confirm or deny its authenticity?
Nonsense. This article was completely invented by the editors of the magazine, and has nothing to do with the canon (which states that Potara is stronger, by the way). For example, this garbage is also their work. They did a lot of this. There was even a scan (I won’t find it now), which said that Zamas was stronger than Daishinkan. Only all this is non-canon
Herms from Kanzenshuu already delved into this. Originally in the manga Potara was superior. But as of current and in all current media dance and potara are equal, the only thing not equal is the time for each fusion.
I believe that Toriyama stated that in a long battle, it woulb be Vegeto who would win. In a short one, it would be Gogeta. Gogeta is more powerful, but Vegeto's fusion lasts longer. If Vegeto could last longer than 30 mins. Vegeto would win by default.
