Chaos is a secondary character in the Sonic the Hedgehog series, acting as the main driving point for the plot of Sonic Adventure. He's a slow and powerful heavyweight who can easily launch/beat up enemies and has a rather wide variety of ways to attack, at the cost of low mobility and lackluster aerial game. He's the 17th character in B.O.K.Oand was created by Sr.Wario.
This mutant was originally a cuddly Chao, but longtime exposure to the Master Emerald mutated it into Chaos, the protector of the Chao. After an attack on the sanctuary where the Chao lived, Chaos became the monstrous Perfect Chaos and laid waste to his enemies. Sealed away for thousands of years, he now waits to be freed by some idiot like Dr. Eggman for their own nefarious purposes.
Chaos throws a punch at the enemy with his stretchy arms. It does 10% damage if it lands.
Chaos briefly becomes Chaos 4 and leaps toward the opponent to bite them and do 8% damage.
Chaos briefly becomes Chaos 6 and whips the opponent with his tail to do 15% damage.
Chaos becomes Chaos 2 and punches the ground to create a shockwave that will do do 5% damage. If you get hit directly by the hit, it'll also do 15% damage.
Chaos creates a blue aura around himself. Anyone who touches the aura will be stunned for a few seconds, leaving them open for attack.
Chaos blasts a jet of water from his hand. It does no damage but will push enemies back and can be used to cancel some of their attacks.
Chaos throws his stretchy arm upward. If there are any platforms above him, he'll grapple straight to the platform, and if any opponents are grabbed onto, he'll fling them downward, making this a good recovery and kill move.
Chaos morphs into his water form. Here, attacks will do no damage to him and he can move around freely, but he can't attack or jump. Good for avoiding powerful attacks if timed right.
Chaos absorbs the negative energy of the Chaos Emeralds and turns into his terrifying form known as Perfect Chaos.
In this form, only attacks to the brain will hurt Chaos, he's incredibly large, he can fire powerful mouth beams, create small tornadoes, and the stage fills up with water for a period of time.
Chaos transforms into Perfect Chaos and fires a powerful energy beam from his mouth at opponents, melting them instantly.
