I plan on picking Oshawott for my run of White 2. The little ice cream beaver has really grown on me since I've seen him in the anime. And the battle animation of him juggling his shell is to die for. The thing is too cute for my naive heart.
For Black 2, I'm gonna pick Tepig, who was my first Unova starter in BW1.
Snivy is up in the air. I plan on starting a new game in Black1 one of these days, and I planned to use Oshawott, but perhaps that will change. For Black 2, I think it all depends on what my other team members will be. I don't know yet, but it'll probably be Tepig for that one.
