The Pyrite Bldg (Japanese: パイラのビルPyra Building) is a location found in Pokémon Colosseum. It is a run-down old storage building where Miror B.'s minions distribute Shadow Pokémon to Trainers who've won the Pyrite Colosseum challenge. There is an elevator leading from the top floor to the bottom, which can only be accessed from the top due to a one-way door at the bottom floor. Another elevator at the bottom floor provides access to The Under, but requires an Elevator Key to be accessed and used. The entrance to Pyrite Cave is located on the roof.
Trainers with a Poké Ball by their names may be challenged for a rematch after defeating certain bosses. In a rematch they may have higher-level Pokémon, and any Shadow Pokémon previously caught will be replaced.
