Sigh...so many posts, no time to read em all!
Well, Dartrix...is Dartrix, and appears to have some sort of cape. Could evolve into Groot.
I can't see Brionne evolving into anything else but that leaked final. Popplio might be not have a gender specific design, but Brionne does, and looks like the young girl with pig tails. The leaked final to me feels like an analogt her growing into a woman, and an enchanting one at that. Hopefully, for once, they reversed the gender ratio.
And finally, we have Torracat. I didn't like Litten very much. The whiskers made him look like unkempt. But Torracat looks poised and confident, like a brand new Jaguar ready to tackle to road. If he is to walk on two feet, I'm glad they held off on making him bipedal for the first two forms.
And why don't people like the leaked final for that one? Is it because he pees fire? I mean, he's this tough, muscular looking beast, and is the one I'd feel most comfortable with taking on the Ultra Beasts going by looks alone. He is what the Lycanrock night form should have been IMO.
And it looks like they nerfed Greninjash before he was even released. Not being able change him like in the anime is going to make him underpowered, especially without the Protean boost. It would probably would have been better to have him change once a quarter or half of the opponent's health was gone, so he could be useful in Ubers. There wouldn't even be a point of breeding Battle Bond even if it was possible, because Protean would be better overall 9 out of 10 times!
