It has happened a meloetta event for black/white 2 for those in Canada,Australia,New Zealand and the US. Starting March 4-25 anyone in the US can get their meloetta at any gamestop. Canada, Australia, and New Zealand will be able to get their meloetta on March 9-April 19.(sorry about the end date. Looking again I'm not sure the end date for Canada but more likely its the same) Level,attacks, or if it is holding an item are unclear as of now.(keldeo notice under pic)

Also keldeo event is ending at the end of the day so hurry and get it if you don't have one yet
