First playthrough of Pokemon Gold (Original), I picked Chikorita (I wanted Totodile but my bro picked it first and at that young age, I wanted to have the 'type' advantage).
Long story short, I hated Chikorita so much (Especially after Falkner) that by the time I was at Ecruteak, I straight up boxed (then Bayleaf) after I caught Heracross and my Eevee evolved into an Espeon (those two ended up becoming my core Pokemon as well as my two favorites). I also had Mareep and Gastly from after the first badge so I was fine for the rest of my playthrough.
Final Team for E4: Espeon, Heracross, Gengar (thanks bro) Red Gyarados, Ampharos and Ho-oh.
