Kanto - Bulbasaur
Johto - Cyndaquil
Hoenn - Mudkip / Treecko
Sinnoh - Turtwig / Chimchar
Unova - Snivy / Tepig
Kalos - Chespin / Froakie

So:
Fire: 3
Water: 2
Grass: 5

Kanto: Bulbasaur
Johto: Cyndaquil
Hoenn: Treecko
Sinnoh: Chimchar
Unova: Snivy
Kalos: Chespin

Grass: 4
Fire: 2
Water: 0 0.0

I never realized that ,aside from pokemon yellow, I never owned a water starter.

Kanto:Charmander
Johto:Cyndaquil
Hoenn:Mudkip
Sinnoh:Chimchar
Unova:Oshawott
Kalos:Froakie(never played X and Y,But that's what I'd choose if I'd have it)

Fire:3
Grass:0
Water:2
So Grass is the least used,Water's the second,and Fire is the most used.

Fire and Grass are the ones I go after!

I know that I picked Snivy for Unova, but I rarely pick grass types. There just not my kind. Fire starters are my pick and I usually go for water starters next, so grass is my least favorite.

I do like the grass starters. But the only one I've actually chosen in a main game was Treecko in Emerald.

For some reason, I hardly ever pick a Water type starter.

The only Fire-starter that I really liked are Charizard/Charmander and Blaziken/Torchic.
