Duon

Duon is a boss in the game Super Smash Bros. Brawl, fought by Snake, Peach, Shiek, Zelda, Fox, Meta Knight and Lucario. It's actually two robots in one-a pink one and a blue one formed together. Palkia and Dialga resembles this strange monster. After Snake had kicked all the Mr. Game & Watches out of the window, the Game & Watches had turned into Shadow Bugs which then formed into Duon. After the team defeated Duon, Duon transformed into a Mr. Game & Watch trophy that Peach revived. Duon is fought later in The Great Maze and has the same attacks.
