The Ruined Hall is a stage in the Subspace Emissary of Super Smash Bros. Brawl. It is a straightforward stage, containing only a boss battle against Galleom for the second and final time before entering the Great Maze.
The playable characters are Lucas and the Pokémon Trainer. After the battle, Galleom's head reveals a Subspace Bomb, which is set to detonate over the ruins in 15 seconds. Pokémon Trainer has fainted, but Lucas uses PK Thunder on Galleom's arm, blowing it off, sending Lucas and the Pokémon Trainer back down to earth. Lucas is too scared to do anything about crashing, but fortunately, Lucas and the Pokémon Trainer are saved by Meta Knight. Wario's trophy, defeated earlier, is sucked into Subspace, along with the ruins.
- Since the level purely consists of a Galleom boss fight, Boss Battle Song 1 plays throughout the level.
- In the ending cutscene, a small part of Menu 1 plays.
