How can I get Dialga, Palkia and Giratina in Black/White 2?

Question

In a tower, I found the Adamant, Lustrous, and Gistreous orb.
I was wondering if I could get those Pokemon in the game?

Answer 1

Dialga, Palkia and Giratina aren't available through regular gameplay in B2W2, even though you can get their orbs easily. Here are your options:

• Migrate them from a Gen 4 game (DPPt, HGSS) using Poke Transfer, which requires a second DS and obviously the extra game
• Catch them and transfer them from Pokemon Dream Radar, a spin-off game for the 3DS (only possible if the relevant game is inserted into the console, e.g. Platinum for Giratina)
• Receive them through an event via Wiimmfi, which will connect you to a custom server that runs expired events; see here for how to do it

Answer 2

No you can't get them in the game but there is currently an event for them.

Answer 3

You can't get those guys normally, but you can get shiny ones from an event currently going on.
