Why, in the name of all that is holy, is Snivy not the Kalos Grass-Type starter?


At first glance, there's nothing inherently wrong with Snivy being a Unova Pokémon alongside Tepig and Oshawott. Aaaand then you take a look at Serperior's design concept, which trickles down throughout the entire family. Let me put this into perspective. We are looking at a Pokémon here who is not only based off of French royalty (the country Kalos is based on), but was released in the
very region that came before Kalos and STILL didn't have any competitively viable niche until- you guessed it! Generation 6, which just so happened to be the very same generation that released the Unova starters' hidden abilities for the first time AND even buffed the Grass-Type a little bit as an added bonus with their new spore/powder move immunity.
As if all of that wasn't bad enough, with some simple switching around the Unova and Kalos starter positions, not only can Snivy's placement be resolved, but we can do that while still having two balanced starter Pokémon trios AND creating a gap in the controversial Fire/Fighting starter pattern as yet another perk of this decision! For Unova, let's go with a trio of Chespin, Fennekin, and Oshawott, and for Kalos, let's go with Snivy, Tepig, and Froakie (the latter two also fit the hidden ability point better than Oshawott, I might add).
I'm sorry, guys, I just... I will never look at a Grass-Type Pokémon with
literal inspiration from the "Rose of Versailles" and the queen of the same name background and think
"Oh, that's definitely a Unova Pokémon."
