>>25240571Chestnaught is fine, nothing wrong with it.
Greninja is also fine, although its ability is a bit on the strong side. Some fags will try to tell you it should be covered in bubbles, and they sorta have a point, but I think it's okay the way it is.
Delphox went wrong because they made it into a furbait biped in its stagve-2 form. It ruins the appeal behind Fennekin because it goes from being a cute pet fox to... whatever the fuck Braixen is. Worst still, it's 75% male, so most of those Braixen are crossdressers. And delphox looks like an old wizard man, so it even alienates some fans of Braixen. They couldn't fucking decide what they wanted the Delphox line to, so all 3 stages suffered. And you can make a quadrepedal wizard, by the way. It's not that hard. In /tg/ I've read stories about actual non-anthropomorphic dogs that can't talk being wizards, and in pic related someone was a Bear/Rogue. So it can be done.
