Kyuremu, the 3rd legendary Dragon:
I wonder what it's story is. It doesn't seem as interesting as Reshiram or Zekrom. I mean, the version mascots have White Forest and Black City, respectively (I think that's how it is), but Kyuremu (Ice/Dragon) will undoubtedly get special treatment in the third version like always (i.e. Suicune, Rayquaza and Giratina)
