Nintendo has announced the first unique Pokémon distribution for Pokémon Black & White games in the US. This giveaway is a special Banette with its Hidden Ability of Cursed Body. This Pokémon is obtained via a password to be given in the next Nintendo Power issue and is accessible from yesterday (9/15/2011) until 3/1/2012. Providing the password isn't a unique serial code seen in the Japanese versions, I'll post up the info as soon as it becomes avialable.
In addition to this, the special Togekiss present started this month, giving the ability to receive a Togekiss with Super Luck in the month of your birthday, as set in your Trainer Club account. When it's your birthday month, you'll receive an e-mail regarding it within the system itself in your Trainer Club Account.
