I am probably GT's biggest defender, and for the longest time held GT just as canon as anything in the universe.Cetra wrote:Side story does not mean not canon. And going by the rules of Dragon Ball asking again would probably even result in different answers because opinions were changed - even if they were different before, which I do not believe.Confidence Matters wrote: The only difference between GT and BOG & ROF is that GT was stated to be a side-story based on the events of Z - it's canonicity was noted otherwise by AT, and only its canonicity. Which makes it a non-canon continuation.
But I recently learned that Akira used the actual words "side-story" to describe GT, and not simply an ambiguous "gaiden" (which could also mean "tale"), in I believe the GT Dragon Box.
I don't know japanese and was told this by Vegetto from here on r/DBZ, so take it for what you will. But if it is true he referred to it as such, using those exact words, GT is not canon.
I guess you can say that Future Trunks' timeline featured in the manga is also a side-story that is obviously canon, but that was a different timeline altogether - so if anything, GT is also a different timeline altogether based on the events of Z.
I guess we will see in the future if AT writes anything that contradicts GT in GT's timeline placement.
