Gen1 Pokemon that actually look good.

[Thomas Elliot]

I remember Yellow being such an improvement over R/B, I know part of it was the fact that we could see the sprites in color now.
As far as R/B is concerned, I think pretty much from Staryu until Mewtwo, with a few exceptions (Articuno and Moltres for example), pretty much retain their same style today.

[Felmarg]

I think that dratini and dragonair look pretty good in yellow. They are the right colors!

[Trace★]

Golbat for sure xD

Look at that tongue!

[Greekboy]

Nidoking and Nidoqueen have good sprites, look identical to their art.

[Zoruagible]

I loved Squirtle's sprite. Gengar's was cool as well

[HoorayForJay]

Beedrill looked badass in yellow.

[Pilpulp]

For sprites I liked, Staryu, Jolteon, Zapados, Lapras, Jigglypuff & (of course) Pikachu.

[Lucario95]

Arcanine looked awesome in the Yellow Version

[^Cutty^]

I like how most of all water pokemon looks at that time.

[RondezView]

I love Jolteon in Green! He looks so happy and talkative. (Don't ask me how a pokemon can look talkative, but Jolteon does.)

[John Wallrein]

I like Dragonite's sprites in Red/Blue and Yellow. They actually looked "tough" and aggressive which when I think of a Dragon with strength like Dragonite has I want it to look like that. The later gen's after it made Dragonite look more like a gentle teddy bear.

[PopPrincess_Lyra]

Meowth's sprite in Yellow was the best one throughout the whole game series tbh :3 nya~

[TheGreatArcher]

Psycho!!!!!!!! Lol..................................!!!!!!

I like yellow's sprite for Geodude. It's nicely shaded, it's in a cool pose, and it resembles it's anime counterpart.

[lugia used splash]

I quite like all of Gravelers Gen 1 designs.

Its too bad Golems gen 1 sprites are pretty bad..

[Doggiedoggie]

It was gen 1, they all looked good. This was back when they had good ideas.

[Dragontail]

I thought Golbat's Gen. 1 design was alright. The R/B one was the best.

[Chriiis]

I'd have to say Aerodactyl, it's one of the ones that sticks out to me as not looking nearly as generic; It looks closer to it's real self.

[pacman000]

^Yes indeed.

Blue's Mew sprite is cute. Green's...let's not go there.

My favs are Rapidash and Dragonite

[Sabrina's Doll]

Rapidash in Red looked gorgeous. I was disappointed that you had to wait near the end of the game to even catch one.

[jailo]

Hitmonlee was good and if i remember right i think Lapras was alright aswell

[Rayze Darr]

Snorlax, Aerodactyl and Haunter all stand out to me as being pretty near-flawless sprites. They could easily be colored in and used in any of the GBA games with no complaints.

[AnonNekomata]

In Red/Blue: I like Ivysaur's sitting up pose- it's a shame they didn't do this in any more sprites afterwards. Fearow, Meowth, Rapidash, Seadra and Moltres (with its unusual style) are quite lovely, for such old sprites. And Golbat is getting an honourable mention because... well... it's certainly one of the more memorable sprites. If only for how outright bizarre it looks.

In Green: Pidgeot is getting a mention, deal with it. I happen to like its pose- the R/B one just looks like one of those wooden bird things that you often see tipping into a glass of lemonade. Ninetales is absolutely gorgeous and by far my favourite Green sprite. Fearow, Ponyta, Rapidash, Tauros, Jolteon, Flareon and Aerodactyl are all quite nice, too. And Mew does look a tad like some sort of alien creature, but the pose is interesting. XD

In Yellow: There was a serious step up in sprite quality. Everything looks pretty good, for the graphics at the time. Ninetales, Persian, Rapidash (for a third time- it just has some really nice poses and sprites!), Dewgong, Scyther, Lapras and Articuno are some of my personal favourites. Although I think my favourite overall is Dragonite- it just looks so determined!

[darkerkyurem6]

Nidoqueen is decent.
