I don't know if this would be considered a spoiler but I'll tag it as such anyway. Something I've noticed about ZA is how many Pokémon are missing from the Kalos Pokédex. And before anyone wants to "well, actually" me and say that they've seen someone online talk about this, well I haven't so I'm gonna bring awareness to it.
I wanna say I'm not trying to bash the game necessarily but it does upset me how many Pokémon were removed. Especially my babies Azumarill, Quagsire, Beartic and Bellossom 🙁 – Don't get me wrong I've liked ZA so far, I'm just someone who found this out yesterday and wants to talk about it. I know that the game takes place in one city so having every Pokémon might've been a lot (especially the sheer amount of ocean Pokémon with no ocean) but it's still disappointing. If I'm wrong and just missed one or two of these please let me know I'd be very happy to be proven wrong!!! Anyway, without further ado, here's every Pokémon that was in X/Y that was removed from ZA.

NOTE: + means that Pokémon + their evolutions. Pokémon that IMO have a "sibling" are being lumped into one because this post is long enough (i.e. Plusle/Minun, Sawk/Throh, etc.)
Also no Ditto but makes sense due to no breeding.
