Oh, before Goku shows up to save everyone. Tienshinhan shows up to save everyone. Wow, unique. That hasn't happened since the previous arc. No idea why Toriyama decided to put that in there. Probably just to appease Tenshinhan-fans but it's pretty bad imo as it adds nothing.
Introducing another form of fusion is also weird and I never got why Toriyama does it. He could have written around the time the dance takes somehow. Like, I dunno, have another character show up to give them some time. Like, I dunno, Tienshinhan?
Well, this fusion is different, because it's permanent.
well, this week it is.
