I like all the fire types final evolved, especially Incineroar, after watching the anime just released. Poor Delphox and Emboar
I have to say Typhlosion. It's generic...but then again I didn't like any of the 3 Johto starters to begin with. Could also argue that it's vanilla attributes are its greatest strength since it has no specialization whatsoever. In terms of design though; Delphox is my least favorite. For a Pokémon that looks overly feminine, it's definitely odd that it has a 3-1 male/female ratio. Same thing with Primarina.
At least, someone pointed out the fact that both Braixen and Primarina are the only starter lines that are more feminine in design, but have high male to female gender ratio. I don't mind this weird Gamefreak design idea. But it will open up many roleplaying opportunities whereby the character looks female and when that character announce he is male, everyone else lose their footing.
