Grass:
precious. arboliva is nice too, grass-type families havent struck such a chord in myself ever. its probably my favorite grass now with arboliva coming at a close second.
Fire:
probably my favorite pokemon introduced in g9 this mon is beautiful its MY little flaming goldfish. competitively its hilariously powerful too, definately something you'd not expect from the tiny goldfish of the group. also, its kinda neat how canonically chi-yu can beat the other four, since its scarlet entry explicitly state it can easily melt rocks and sand, meaning it can just, kinda, destroy ting-lu's body. and obviously the 5400 fahrenheit flaming goldfish would make quick work of the animate snow and pile of dead leaves.
Water:
isnt it adorable
its also got some shockingly nice (minimaxed) stats, complete with np. pretty neat.
Normal:
[godly gift]
dudunsparce used boomburst!
Electric:
competitively i love this thing. the thing is right now, almost no (meta) electric switchins would like to take an earth power and vice versa, making shocks stab combo shockingly (heh) good (if slightly prediction reliant). not to mention how cool hadron shocks is in aaa. design-wise ive grown to like it, it just looks neat.
Psychic:
i really like the design, even more than ceruledge's initially (though ive grown to like ceruledge more, mostly because armarogue's psychic typing threw me off so much). i strongly believe it 100% looks like a not-psychic type tho. still, its not like its competition is impressive, to me anyway.
Fighting:
im completely obsessed with this mon competitively. the sheer magnitude of sets it can run is totally unreal. not to mention with flutter banned in many places valiant becomes the de facto offensive fairy. design wise...i just like it. i really, really like it. idk why. maybe because i already like gardevoir and feel that mixing it with gallade's bades only made it better? its still my second favorite mon of g9 tho.
Rock:
its so pretty. glimmora's showdown sprite (and whatever sprite it was taken from in-game) does not do it justice. when it opens up like ingame it is perhaps the prettiest mon in all of g9 and i love it. competitively it really has potential to be a nice disruptive attacker with an interesting typing, nice coverage, and corrosion to uniquely disrupt stuff. but of course its other ability toxic debris, access all hazards except webs as well as dual screens, signature mortal spin, and memento automatically fates it to be locked into ou as a suicide lead, at least for now.
Ground:
clod.
Flying:
i probably like bombirdier a bit more mostly because jugulis is weirdly small, even smaller than regular hydrei. but hydrei has been one of my faves for a while and it just looks cool. competitively dark/flying is neat and it gets some really cool coverage, but gf didnt give it np or roost like the morons they are. bombirdier imo just looks nice. rocky payload is also a really cool ability mostly because rock is such an underused type in both bh and aaa, i wonder what people will do with it.
Bug:
the complete lack of competition helps. it is also hilariously over 3 meters tall, making it the biggest bug AND the biggest fighter (even taller than koraidon, mind you). which is just hilarious imo. the massive size also looks incredibly comfy to just snuggle in. competitively i fit it on surprisingly many teams as one of the better great tusk answers around, and fimp wisp and uturn are all such nice tools. it also helps that volcarona is one of my two favorite pokemons, although i still greatly prefer volc to slither.
Poison:
again, volc is one of my two all-time faves (other being dewgong). and i think iron moth's design is really cool. i like the showdown 2d model more than the in-game model, honestly. it just looks so geometric. competitively boots pivot moth finds its way on a couple of my teams and i really love using it. in aaa its desoland set both hit hard as hell (thanks to being a 140 spa fire) and is one of the best checks to primsea iron bundle, which is neat, though resists to its attacks are so unreasonably common.
Dark:
chi-yu aside, im again indecisive, though im leaning towards moon a bit. moon's design is just so wickedly cool imo and ive always been a fan of mmence. competitively im a fan of vanilla dd/acro/eq/crunch set because ground/flying is so damn good and moon is so damn strong. with chien i just like ice-types, i think it has a neat design (not as much as moon's tho), and competitively in stabmons chien goes completely nuts but even outside of that dark/ice with that stat spread and sword of ruin is so strong. yes both of these outrank jugulis and bombirdier.
Ghost:
i tried to keep it exclusively to sv, but hisuian zoroark hit home for me in so many ways i could not not put it here. the typing, the design, the very neat competitive merit, the typing.... and the design and typing....
with sv its these two. ive always been a fan of ghosts and they both just look nice. ceruledge's design is so elegent although i do wish its legs were a bit less, err, wide. playing with opulse ceruledge in aaa is definately what made it on par with flutter imo tho. flutter is just a bigger, fancier misdreavus, but i think thats what misdreavus needed anyway, so no qualms with that. ghost/fairy also happens to be the two most spammable stabs in the game (tarrows aside), and i enjoy clicking a stab and seeing almost no resists on the other side.
Ice:
3 way tie. bax looks like naked duraludon with a spike attached but somehow doesnt look too bad and dd glaive rush sets completely sold it for me. people say tera ground is the way. i disagree, teras dragon, and cancels the poor unfortunate soul standing in front of me. who cares about the drawback when the guy in front of me dies and the guy that comes in next also dies. bundle is just what ive always wish gf did with an ice-type. its fast and strong and posess an amazing stab combo. effortlessly taking kills with this in aaa is kinda fun ngl, althought that may make me kind of a sadist. ive talked about chien in the dark section. these three were just, generations of ppl wanting good offensive ice-types coming into fruitation. and i love them.
Steel:
ik this is pla but i dont rly like any of the sv ones. im not a huge fan of goodra either, but im still kinda pissed they took away overcoat which wouldve made it so damn good in bbp. rip 90/8/12 bulk with dragon/steel that evolves from base goomy = does not have a completely terrible g9 movepool.
Dragon:
all talked abt above
for the covers i prefer korai slightly designwise but mirai competitively almost everywhere. bh finally gets a good special electric.
Fairy:
both valiant and flutter (my second choice) are already up there, the other ones arent bad. fidough is absolutely adorable and scream tail is neat and has pixiburst in oms where it can access it, which is cool. but valiant is still so far and away #1 here i cant stick them in this slot in good faith.
