1st Gen Favorite 1st Gen Pokemon?

Pikachu for Sure!

For many years Jigglypuff was my favorite, now it is more of Sandslash.

MY top favorites include
Jigglypuff
Sandslash
Articuno
Mewtwo
Flareon
Haunter

I'd have to say Starmie. Though that came about more because of my Soul Silver playthrough than any of the 1st gen games.

Runners up would be Gengar and Lapras.

Marowak is my favourite Pokemon of all time!
Bulbasaur second and Nidoking in third.

Haunter, the design of the Pokémon it's evolutionary tree Gasty Haunter and Gengar's numbers in the National Dex 92,93,94.

10. Scyther
9. Ninetales
8. Vileplume
7. Arcanine
6. Butterfree
5. Vaporeon
4. Clefable
3. Lapras
2. Raichu
1. Rapidash

my fave first gen pokemon is also my all time fave one Flareon, used to like jolteon slightly more in gen 1 but when I played through kanto agin in lefgreen flareon became my new fave since it did so well on my team

My favorite first gen Pokemon is probably Lapras.

Charizard because Charmander was my starter and I couldn't help by get attached. I also like Machamp, Snorlax, Electabuzz, Magmar, Jynx, Scyther, Pinsir, Hitmons and Mewtwo a lot. I'd order them:

1. Charizard
2,3,4. Electabuzz, Magmar and Jynx
5. Mewtwo
6. Snorlax
7,8. Scyther and Hitmons
9. Machamp
10. Pinsir

Snorlax, Lapras, Scyther, Aerodactyl, Omastar, Kabutops, Jynx, Mr. Mime, Hypno, Raichu, Venusaur, Golbat, Kangaskhan, Tauros, Exeggutor, Venomoth, Vaporeon. Most of the pokemon I like at the end of the Kanto dex are more interesting than the beginning of it oddly enough.

When I was younger, I was obsessed with Mewtwo, but now I don't care for him that much. I guess my favorite now would have to be Staryu.

Charizard and Lapras in my opinion are the best designed pokemon of Kanto

Snorlax ofc

Gotta be the Gastly family ain't it..

Gengar and Growlithe. Gengar because it's awesome and Growlithe because I always wanted a puppy when I was little.

I've changed my mind and I enlarge the "family"

Lapras

I would say my favorite would have to be Ninetails.

Lots of good choices, but it's Poliwrath for me. My other's are Scyther, Gengar, Electabuzz, Golduck, and Cloyster.

OOOOO! Charmander line, Squirtle line, Pikachu line, Abra line, Eevee line, Growlithe line, Gastly line, and Dratini line. So unique. :D
