This Chaos has absorbed four of the Chaos Emeralds. It can move quickly when in water and also has the power to alter the water's environment.


— Official description, Sonic Adventure website[5]

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. He is fought near the lake in Mystic Ruins with Sonic, Tails and Knuckles.

Appearance[]

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

History[]

Sonic Adventure[]

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 he transformed.

Powers and abilities[]

Chaos 4 has new powers over his previous form, including being able to fire energy waves, swimming at high speeds, creating water explosions by slamming his body on water, and turning into four balls that bounce toward the player. If Chaos 4 is out of water, he simply floats in the air. Chaos also can launch an extendable arm, charged by energy to the opponent as well.

Battle[]

Boss guide[]

Sonic/Metal Sonic[]

The battle with Chaos 4 is fought over water. The player must use the lily pads to stay out of the water, and must jump immediately after landing to avoid slipping and falling off. Chaos 4 attacks if he senses the player sitting in the water, thus, it is best to hop around the lake. Chaos 4 uses a variety of distance attacks that consist of multidirectional shock waves. When Chaos 4 stops attacking and pokes his head up, just as the Chaos before it, Chaos 4 breaks into small pieces, then reforms. It is best for the player to stay out of Chaos 4's way until he pops up, then let him have it with a normal attack.

Tails[]

Chaos 4 is fought over water. As Tails, stay out of the pond as much as possible. Chaos 4 attacks quickly when Tails lands, so the player must jump immediately to dodge Chaos 4's attack. It is best not to fly farther than the player needs to and stick close to Chaos 4. Chaos 4 is temporarily vulnerable when he rises. Quickly land near him and attack. The reforming energy balls can hurt the player if they are not careful. It takes four hits to sink Chaos 4.

Knuckles[]

At the time the player faces Chaos 4 as Knuckles, they have previously seen the Chaos monster's fourth incarnation while playing as another character (whether it be Sonic or Tails). Knuckles has trouble getting out of the pond if he falls in. The player must make quick stops on the lilypads and wait for the monster to peek up. Knuckles can land beside Chaos 4 and use his punching attack to damage Chaos 4, though there is a risk at getting hit. Alternately, the player can ball up and drop on the monster from above. It takes four hits to sink the beast.

Although Chaos 4 had the environment advantage, it still lost the battle. It later appeared on the Egg Carrier where Eggman turned it into Chaos 6.

Trivia[]

  • According to Sage, Wyvern may reference one of the five Ancient Tribes, with a tail developed instead of legs, hence Chaos 4's appearence.[6]
