Totodile, Torchic, Bulbasaur.
Previously, I had a thing for the bird/flying-inspired starters: Charmander (-> Zard) on LeafGreen, Torchic on Emerald, and Piplup on Diamond.
Nowadays, that hasn't really changed ('cept for Mudkip in Emerald since Roxanne was annoying me), but the 2G starters lack any bird or flying influence. So Water it is. My Zard from FireRed will do just fine, freeing me up for the Kanto Grass starter in SoulSilver, and completing my starter type trinity.
