Minute: 20
Context: after Goku regains consciousness following his fight with Beerus
Goku: “This ain’t good. The only way to get stronger would be to merge with Vegeta…and even then, I don’t think I could win.”
Significance: Pretty much the same line originally appeared in the extended edition of BoG. The word for “merge” here is 合体/gattai, which in Japanese is used to refer to both Potara fusion and the Fusion dance. Though in Japanese the proper name for the Metamorean dance-style Fusion is simply the English word "Fusion" (フュージョン/Fuujon), this is treated as a proper noun and the process itself is referred to with Japanese words for fusing/merging such as 融合/yuugou and 合体/gattai. Goku even introduces the Fusion dance as a 合体技/gattai-waza, "merging technique", when the concept makes its debut in chapter 469. On the other hand, the process of fusing with the Potara is always described as 合体/gattai, and not with the English word "Fusion" or the Japanese 融合/yuugou.
