Neither do I.

How come the title says Black and White, but the tags say Black and White 2? By powered up form do you mean Black/White form?

He means Black Kyurem & White Kyurem.

Answer 1

>While it is not known to evolve into or from any Pokémon, it has two other Formes, which are activated by using the Gene Wedge on it and either Zekrom or Reshiram, resulting in a fusion that removes Zekrom or Reshiram from the party until the fusion is undone. It will then become Black Kyurem (with Zekrom) or White Kyurem (with Reshiram).
