Super Smash Bros. Brawl (The Subspace Emissary) Boss # 8: Wario

The showdown with Wario outside some Ancient Ruins. I have to admit that I'm bummed that they just used the SMB3 Airship music for this fight rather than some of the WarioWare tunes since Wario's level in the multiplayer has some of the best music in the whole game.
