Gen8 - Scorbunny.I'm actually surprised at how many times Ive gone Grass starter now that I wrote that out. Every starter I had was great except Snivy. Seprperior was grossly underpowered amd losing large chunks of health at each attack. Maybe I ended up with a weird Nature combo but since I never pay attention to those things it became the first Starter I had to bench halfway thru my journey.
Amazing, you managed to start with a Gen 5 Pokemon in Gen 6! Poor Chespin, Froakie and Fennekin.
