What did you think of 17 and 18's hypothetical fusion suggested by the Supreme Kai?
Well for one, they would look AMAZING…if we take this Fusion they pulled in Dragonball Heroes with GT!18 and Super!17. I reckon their design would be slightly different of course since they look different in DBS, but you get the gist.
And as long as it can be undone, I wouldn’t have any problems with it. It would have been kinda cool to see that TBH! But like Beerus said, if they get defeated, they lose two people at once so that is why it’s not the best of ideas for now…but still they prolly would have kicked ass!
