This one felt really short, but it was good nonetheless.
I'm not sure what to make of Neva as of yet, I think he's evil, but then again he could be chaotic neutral. I don't think he'd actually translate the wish correctly (speaking of, can't Piccolo access Nail's language skills?).
I like Duu, his dynamic with Kuu is awesome. My partner pointed out how both of them share some mannerisms with Arale from Dr. Slump, which I think is spot on. He doesn't seem all that much more powerful, I hope they form a tag team with the option of fusing later on.
I guess that's it? Everything else was just fighting scenes. Vegeta probably turns SSJ and burts out of there.
Anyway, happy holidays to you guys!
