By the way, if anyone's interested in getting the Therian Formes of the Kami Trio, I've already caught Thundurus and Tornadus and i'm on the process of unlocking the Landorus Extension (almost there). I can lend them so that they appear on the Pokedex.
These Formes are exclusive to the Pokemon Dream Radar. It's a pretty nifty addition, since you can also catch other pokemon there (which will always have their Hidden Abilities), some good items and can also catch other legendaries (with their Hidden Abilities as well) as long as you have their respective cartridge (Pokemon Pearl for Palkia, Diamond for Dialga, etc.).
Edit - The Memory Link is really a pretty nifty thing. On my White's MC house I found both the Unova Pokedex completion certificate and the National Pokedex completion certificate. Brought back some good memories of completing both Dexes
