- Piplup in Diamond
- Bulbasaur in LeafGreen
- Piplup in Platinum (I really liked penguins)
- Cyndaquil in SoulSilver (and HeartGold when I swapped them)
- Oshawott in Black
- Oshawott in Black 2
Weirdly the only starter I have
never used is Squirtle. When I had the time to endlessly replay pokémon I was always either trying to have a team full of dragons or imitate Red from the manga (either way I nearly always had Gyarados and Aerodactyl), so the little turtle was just the odd one out. It doesn't help that Bulbasaur is the only Gen I Grass-type I like, so if I'm planning a team I can always find another Water-type 'mon and do without a Fire-type, but never get a replacement Grass-type.
