Starting May 8th, you'll have the chance to pick up the legendary Deoxys through the Nintendo Wi-Fi Connection service in Pokemon Black and White 2 -- who will also be appearing in the Pokemon trading card game next month. Once you pick him up digitally, there will be a place in Nacrene City where you can change its form to suit different combat capabilities (also known as "Formes"). Details on how to obtain him and what his unique moves are will be revealed at a later date, but for now, mark your calendars.
For those of you who don't play Pokemon, Deoxys is a rare event legendary creature from the third generation of the series (Ruby, Sapphire, and Emerald, on the Game Boy Advance). You can't catch him in the wild, and he's only been available at a few select events -- including this one. Remember that you can grab one for each copy of the game you own.
