Complete the Underground Ruins in pokemon black white 2 to battle and catch Regirock, then use the Key System to find Registeel or Regice.

Walkthrough
  1. 1
    Move into the large open area. Speak to the man on the north side if you wish, but he does not battle.
  2. 2
    Locate the concentric circles on the north side. Stand on the center of the smaller circle.
  3. 3
    To solve the puzzle, head through the stone doors ahead and inspect the stone statues for clues. If it is daytime, you will need to return at night, or vice versa, to see the complete clue.
  4. 4
    The solution is: From the circle in front of the door, move exactly nine tiles east, then six tiles south. Keep facing south and press the ‘A’ button.
  5. 5
    When asked a question, answer with ‘Yes’. The ground will shake, indicating the puzzle is solved.
  6. 6
    Go through the stone door again. The room will have changed. Head north to the statue.
  7. 7
    Move through the gap between the rock and the wall on either side of the statue.
  8. 8
    Follow the path around until you reach a thin path leading north.
  9. 9
    Follow this path to reach Regirock. Save your game before interacting with Regirock to begin the battle.
Tips
  • Wild Pokemon in the cave include Onix, Nosepass, Lairon, Boldore, Woobat, and Durant. In dust clouds, you can find Onix, Steelix, and Excadrill.
  • Ground-type Pokemon or those with Volt Absorb or Lightning Rod abilities are recommended for the Regirock battle, as it only uses Electric-type moves like Zap Cannon, which can cause paralysis.
Walkthrough
  1. 1
    Exit the current area back to the large cavernous room. Save and exit the game.
  2. 2
    From the main menu, select ‘Unova Link’ (4th option).
  3. 3
    Select ‘Key System’ (1st option).
  4. 4
    Select ‘Key Settings’.
  5. 5
    Select ‘Mysterious Door’.
  6. 6
    Select the newly unlocked key (Iron Key or Iceberg Key) to make it active.
  7. 7
    Exit back to the main menu and re-enter your game.
  8. 8
    Head back to the starting circle. Move nine tiles east and six tiles south.
  9. 9
    Turn the switch on and head through the door.
  10. 10
    Go to where you encountered Regirock. A new Regi will appear. Save your game before interacting with it to begin the battle.

Legendary Pokemon Battle - Registeel/Regice:

  • If playing Black 2, you will battle and can catch Registeel (Level 65, Steel-type).
  • If playing White 2, you will battle and can catch Regice (Level 65, Ice-type).
  • Both Registeel and Regice, like Regirock, only use Electric-type moves. Ground-type Pokemon or those with abilities that negate Electric-type moves are highly effective.
Walkthrough
  1. 1
    To encounter the final Regi, you must trade the key you obtained (Iron Key or Iceberg Key) from a player with the opposite version of pokemon black white 2 using the Unova Link Key System.
  2. 2
    Once you have the key for the other Regi, activate it using the Key System as described previously.
  3. 3
    Repeat the process of going to the starting circle, moving nine tiles east and six tiles south, activating the switch, and heading to the encounter location.
  4. 4
    Save your game before interacting with the final Regi to begin the battle.
Tips
  • It is recommended to obtain all three Regis (Regirock, Registeel, and Regice) by trading keys if necessary.
  • Once you have all three Regis in your party, you can encounter Regigigas in Twist Mountain.

To reach Twist Mountain:

  1. Exit the large cavernous room via the south exit.
  2. Head south-west to the minecart line and follow it west over the boulder.
  3. When the minecart line turns north, follow it in that direction.
  4. Pass the Pokemon Ranger to your north.
  5. Continue until you reach the doorway at the end and enter Twist Mountain.
