What are all the legendaries I can find in Black/White 2?
Unlike previous games, you can catch all three Regis in one area. The difference is that you can only obtain Regirock at first, and you have to solve a puzzle which can only be discovered by visiting the area at day then at night. After obtaining Regirock, you will unlock the Steel Key in Black 2, and the Iceberg Key in White 2. You must activate the key via the Unova Link, and then you can obtain the respective Pokemon. You can obtain all 3 in one game if your friend shares the other key with you via Unova Link. All 3 are Lv. 65, further confirming that there is some villainous work going on keeping all these trio Pokemon at level 65.

I know. I put the link to the site I got all the info from. That explains it there.
Uh, you forgot the other forms of Tornadus, Thunderus, and Landorus. You get them with Dream Radar.
There are even more legendaries than what Dex master said.Anddexmaster tornadus, thunderous and landorus cannot be caught in white and black 2.
Is there a Pokemon in black and white 2 to save my masterball for?
Do you get another chance to catch Terrakion in Black and White 2?
