Pikachu from Pok?mon Yellow. But I didn't really get switching the party order to change who comes out first. Pikachu ended up around level 60 while the rest of my party was at level 30. lol I also beat Brock with a Pidgey because I didn't know Mankey would have worked. I was such a good trainer.
Chikorita from SoulSilver. I gave it the most stupid name ever, "Jumpy" because I noticed its sprite jumps around, but then I realise all of them do it. I still have it today as a Meganium.
Bulbasaur back with Pokemon Blue! <3
It's fun to hear about all the younger people that started with later games... it's so nice that your first ever starter can be on the current gen games by transferring it.
