My first was a female Pidgeot in FireRed. My sister traded me three Pidgey because I was giving her some of my Pokémon. Two weren't nicknamed but one was nicknamed Rusty (which was supposed to be a bad thing) and I decided to train her using the VS Seeker on Cycling Road, just outside of Celadon City. Originally, I planned to evolve her to a Pidgeot, just to complete the Pokédex and I would deposit her into a box for the rest of eternity afterwards. Anyway, I used the Exp. Share for ages, using my Charizard to battle. Eventually though, I began using her on her own and after a while, she overtook my Charizard and became my favourite Pokémon.
