I want an Onix pre-evo. I want Pebblix. I will not be satisfied until I get Pebblix. Give. Me. Pebblix. Now. Aside from that...more birds. A Kingfisher water starter would be amazing. More inanimate object Pokémon generally, because they're the best. Anything but more anthropomorphic furry bait will be fine, though.
BIRDS, BIRDS, MORE BIRDS. Especially legendary ones. Despite the fact that there are already five different legendary birds, if you don't count Lugia. In all seriousness, though. For the generic, early-game bird Pokémon, I'd like to see a non-normal type bird. Something similar to what they did with talonflame. Maybe a fairy or ghost type, as the only Ghost-flying Pokémon that exists is Sensu-style Oricorio, and a Fairy-flying one has yet to exist. I'd also like an evolution for Farfetch'd so that it wouldn't be so crap.
Don't worry, Lugia is nowhere near being a bird! I also would like to see more Oricorio styles, but I don't think they'll come in the next generation of their debut appearence. What I really want are some new formes/megas for Lunatone and Solrock. SM where the perfect chance for them and still they received nothing, tho.
All I'm asking for is a dolphin Pokémon. We have had seven generations of Pokémon, and we don't even have that yet? Jk, I'm going to ask for more. I would like to see some more evolutions and pre-evolutions for current Pokémon. Namely Qwilfish, Dunsparce, Sigilyph, and maybe a couple more Eevee evolutions (I'm not opposed).
More unique type combinations! Things like poison/steel, normal/ghost, and most importantly, grass/fire. Less overused/very common type combinations! Normal/flying, grass/poison, grass/bug, dragon/flying, normal/fairy have all had their chances. Let’s shake it up a bit! More evolutions! For Pokémon with no evolutions, like Stantler, Delibird, and Carnivine. More megas! For forgotten/unpopular Pokémon or some who could use a buff, like Farfetch’d, Jynx, and maybe Azumarill. Inanimate object Pokémon! Yes I actually like them. They take a lot of creativity to make, and I know the Pokémon team can do it.
In my opinion we can never have enough ghost Pokémon. I also like Pokémon that are based off of cultural aspects (not just myths and folklore, but Pokémon like Hawlucha and Oricorio). Also, I'm still waiting for an Electric/Poison type Pokémon.
B I R D S GIMME A BIRD OF (almost) EVERY TYPING POSSIBLE WITH FLYING! WE HAVE NO POISON-FLYING BIRDS, NO GHOST-FLYING BIRDS, NO GROUND-FLYING BIRDS, NO GRASS-FLYING BIRDS... ALL THE BIRDS. I WANT ALL THE BIRDS. I WILL MAKE THE WORLD'S BIGGEST BIRD COLLECTION. AND NONE OF YOU CAN STOP ME.
I want more quadrupedal Pokémon. The series seems to have formed the bad habit of taking Pokémon that should be quadrupeds and putting them on two legs for no reason. Also, a Bug-type that actually has more than four legs would nice.
This, let's get some funky types like Fire/Grass, typings we haven't had yet. That would be great be great.
I wouldn't mind seeing a Pokémon that is half centaur, or a Pokémon with more than four legs. I would love to see more mechanical Pokémon, human built robots.
I think it'd be great if the main bird Pokémon wasn't always typed as Normal. Then again, I'd just like to see a Fairy/Flying Peacock line in the game... Oh, and some new Mega Pokémon wouldn't hurt. Gen 6 and Gen 5 didn't get too many (I think Audino was the only Gen 5 Pokémon that got a Mega?) and it still pains me that the starters in Gen 6 didn't get any Megas. If they are planning for DPPT remakes in the future, Sinnoh Starter Megas would be cool too!
