Chaos 4 is the fourth form of Chaos and a boss that appears in the Sega Dreamcast video game, Sonic Adventure, and Sonic Adventure DX: Director's Cut. It is fought near the lake in the Mystic Ruins with Sonic, Tails and Knuckles.


As Chaos 4, Chaos is more fish-like, differing greatly from its appearance as Chaos 1 and 2. Chaos 4 has a shark-like body with a dorsal fin on both its back and a horn on its forehead, and the flaps on the sides on its head have grown longer. It also has two sharp pelvis fins and a pair arms like Chaos 2's, except its hands look more like fins and lack thumbs. Inside its hands and wrists it has grey bones, each with a Chaos Emerald embedded in them. It also has bones running from its tail fin to its belly where it has a pelvis-like bone holding two Chaos Emeralds.


Chaos 4 was encountered after Sonic the Hedgehog and Tails finished their battle with Knuckles the Echidna, where Dr. Eggman stole the Chaos Emeralds they had to turn Chaos 2 into Chaos 4. Chaos 4 proceeded to attack the heroes, but was defeated.

Onboard the Egg Carrier, Big the Cat also encountered Chaos 4, but only briefly before it transformed.

If Chaos 4 is out of water it simply floats in the air. Chaos also can launch an extendable arm, charged by energy to the opponent as well.
