Bidoof and Bibarel.
Garchomp annoyed me in Elite 4.
I really don't like Dragonite (though, I hang around people who really don't like Dragonite, so they may have effected my way of thinking haha). Plus, I lovelovelovelove Dratini and Dragonair... What happened with the next one up, hey? Orange? Yes, favourite colour, but no. Just no.
Geodude and Zubat. I'm sure you all realise why. Ugh.
