The official UK Nintendo site has updated with information on how to obtain the Charizard C-gear skin, the second of the three skins to feature the final evolved forms of the original Kanto starter trio. Our C-Gear Skin page has been updated with the latest information. Below is the press release.

Press Release

If you’re a Pokémon Black Version or Pokémon White Version player and fancy giving your C-Gear a whole new appeal, listen up: over late 2011 and early 2012, three special C-Gear skins will be available via the Pokémon Global Link website, absolutely free. Each one of the skins will be available for a limited time only, so make sure you grab them while you can!

Each C-Gear skin has its own unique password; once you have that all you need to do is log in to the Pokémon Global Link website and use the password in the promotions page. This will unlock the skin for you to apply in-game whenever you fancy.

The Charizard C-Skin is available between October 13th 2011 and February 16th 2012 with the following password: EUPGL102011

Watch this space for news of the remaining limited Edition C-Gear skin coming in November!
