DB Movie 4, to be specific. Does he just continually get stronger throughout the movie? Or are all of the villains (mainly RR arc villains) nerfed to weaker than BoDB Goku?
Definitely seems like he got far stronger. With Z being taken into account, it was likely Toei was rolling with it's GT logic in regard to Zenkais, seeing as how Goku went from comparable to Yamcha who got wrecked by Blue to not getting oneshotted by Battle Jacket Black.
