Yeah, it just felt dumb how they ended it. No Celesteela battle, Soph doesn't get to copy Ash and catch an UB for just a few moments.... it just blasts off, and will probably be the last we ever see of that species. Buzzwole's episode was actually satisfying.
I hope we can see the other UBs actually get to fight. I swear to Arceus, if they solve Guzzlord's problem by feeding it instead of showing it off as a deadly opponent I'm going to be so pissed off. That's the one UB that deserves a battle, a two parter even! And no, I'm not saying that cause it's my favorite.... cause it's not. If you've been to Guzzlord's world, you'd understand.
Also, I really hope somebody other than Ash can catch an UB. Even if it's just for a small moment like Buzzwole, which would be most likely, it'd still be nice to see Kiawe, Mallow and the others.... maybe even the TRio in one episode... get that honor.
