Chao Walker

Chao Walker is a battle suit used by a Neutral Chao in Sonic Adventure 2's multi-player mode. The suit was built for Chao by Tails for unknown reasons. Chao Walker was an unlockable character in Sonic Adventure 2. He returned in the enhanced port Sonic Adventure 2 Battle as a starting character in the multi-player mode. In the GameCube version, a Dark Chao Walker replaces Big the Cat from the Dreamcast version; it is said to be built by Dr. Eggman for Dark Chao.

On Sonic & Sega All-Stars Racing, the Chao Walker and the Dark Chao Walker make a small cameo in the EGGMAN place.
