The Quarter Attack[1] is a move that appears in Sonic Adventure and Sonic Adventure DX: Director's Cut. It is a technique used by Chaos 4 where it splits its body apart and uses them as projectiles.


When using the Quarter Attack, Chaos 4 splits its body into for separate parts which it launches at opponents as water orbs.

In gameplay, this technique is used during the Chaos 4 boss battle. When preparing to use this attack, the Chaos Emeralds will leave Chaos 4's body before said body splits apart and shoot them one by on at the player. These orbs can be avoided by simply moving around. If the player is hit by this attack, they will take damage.
