The Marble Attack[1] is a move that appears in Sonic Adventure and Sonic Adventure DX: Director's Cut. It is a technique used by Chaos 2, where it turns itself into projectiles.


When performing the Marble Attack, Chaos 2 splits its body into several small blobs of water in order to use them as projectiles.

In gameplay, the Marble Attack is used during the Chaos 2 boss battle. Chaos 2 uses this move to hurl the spheres of water at Knuckles in order to damage him. However, these orbs can easily be repelled with a well-timed Punch.
