Toxic to the Touch... I love it. This is definitely my kind of club. <3 I would absolutely love to join this club. Poison-types are what I prefer most of all. But, if I had to choose a pair for partners, they would have to be Arbok and Dustox. I absolutely love them. I can't honestly say they were my favorite most of my life, but I CAN say they definitely grew into who I am now.
Now, for the question topics.
Which Generation Holds The Best Poison Types? Generation I, hands down. They pretty much had the most Poison-types offered throughout the series. Not to mention, Pokemon like Arbok, Victreebel and Weezing really paved the way for what lovely Poison-types we have now.
What Is Your Favorite And Why? I honestly couldn't tell you. I love a lot of them, but I can't put a finger on a favorite. I can't even discover my favorite overall Pokemon, but I'd like to think it would be Arbok, as my fascination of snakes were the one thing I held onto, as well as my obsession with Pokemon. ;P
Least Favorite? Qwilfish, hands down. I love ALL Poison-types, except that one. It's not memorable, and not really likeable. At least, to me.
Who Is Your Favorite Gym Leader/Elite Four Poison Type User? To be quite honest, I don't really like either Koga or Roxie. I know Janine is also a Gym Leader affiliated with Poison-types, but she works the same gym as the same role. A ninja. Not really a fan of ninjas. But if I did have to choose, it'd be Roxie. She's pretty cool, and I'm glad someone finally insisted on a Poison-type expert, but something just irks me about Roxie. But then again, beggars can't be choosers. ;P
Post Script: I hope this is quite alright. I couldn't get a good grasp going about joining, so I cobbled together a few example posts and the introductory post. Again, I'd love to join, Poison is where it's at.
