Bytan

Bytans are a spherical creature with a large eye. It is encountered in the Subspace Emissary mode in Super Smash Bros. Brawl. If undisturbed, Bytans will start multiplying and become much more difficult to avoid. There are also large Bytans that are much stronger than the normal smaller ones. They are identical to a character from the old Game Boy accessory, the Game Boy Camera.
