I must say at page 2 or so of this thread I got terribly confused about what was being argued about but I still found it to be a fascinating read. Everyone here is quite persuasive I think so good job.
This special was released thirteen years after the end of the manga, and twelve years after the last film, Path to Power. It was also released five years before Battle of Gods. I think given all this it was really cool at the time since it seemed everyone wanted a new series then. I remember...
Baby inadvertently facilitating Goku's transformation by wishing for his own planet is brilliant. This so far is honestly one of my favourite arcs in the franchise.
For me it seems more logical to assume that Gokan would be stronger since Gohan >>> Vegeta, but I have no idea how strong the rival boost is meant to be.
