What is the password for Kyuren in Pokemon rumble blast?

Answer 1

Kyurem is not found via a password. There will be roughly a 5% chance that the catapult leading to the area boss will be shimmering, which means that the catapult will instead take the player to a special battle arena where the player first battled Zekrom at the beginning of the game. Here, the player will encounter a legendary Pokémon that will differ depending on the area they were previously in. Upon defeat, the legendary Pokémon will always be recruited by the player unless a confused enemy deals the final blow. Certain legendary Pokémon will only appear once certain circumstances have been met. Most of the lengendary Pokémon will not appear until after the player has beaten the main story.

To find Kyurem, you must have been previously in a Glacier area.
