Chaos

**Chaos** (カオス *Kaosu*?) is the main antagonist of *Sonic Adventure*. Chaos is an immortal, god-like creature composed entirely of concentrated, water-like chaos energy.[5] It was trapped inside the Master Emerald for thousands of years before being released by Dr. Eggman in a plot to conquer the world. Chaos was also the original guardian of the Chaos Emeralds, Chao and the Master Emerald. In *Sonic Adventure,* Chaos absorbed the negative energy of the Chaos Emeralds to attain its final and strongest form, Perfect Chaos.

## Personality

Before Tikal's father and his soldiers came to the place where Chaos and the Chao lived, Chaos was a very loving and gentle creature, being very protective of the Chao and possibly Tikal.[11] But after the Chao that Chaos guarded were injured, Chaos became evil minded and furious at other beings and became completely consumed by anger and rage. When unleashed in the present time, it wanted nothing more than to destroy the world once more, even assisting Doctor Eggman in collecting the Chaos Emeralds to ensure such. However, when Super Sonic neutralized it, Chaos returned to its previous peaceful and gentle demeanour.

## Powers and abilities

Chaos is an incredibly strong creature whose power is so great that it is revered as a god of destruction. Even at its weakest, Chaos is said to possess immeasurable powers.[12]

Chaos possesses the ability to absorb Chaos Emeralds and its form, power and skills change and increases with every Chaos Emerald that it absorbs, until it reaches a fully realized Super transformation. Over time it develops from a humanoid water creature to a horrible, world-destroying monster. Because of its liquid-like appearance, it is also immune to bullets and gunfire.

### Chaos' Forms

#### Chaos 0

In its basic form, Chaos 0 can use his extendable arms that are fueled by energy, to attack his opponent. He is also very agile, being able to jump several tens meters. His body is also bulletproof, due to being a liquid being consisting of chaos energy. He is capable of limited shapeshifting, so he can be in a drip form, that he uses to escape. Chaos 0 is very potent fighter as he could take on Knuckles the Echidna, who is master of martial arts.[13]

Chaos possesses a variety of special attacks, used only by itself. It can deliver a powerful ground punch that creates a small earthquake, releasing a blue energy pulse that harms and confuses enemies, and finally freezes the air around the enemy for thirty to forty seconds. Chaos has some skills of a treasure hunter, that he can search for Emerald shards, or anything else. Being a liquid being, enables it to swim indefinitely.

#### Chaos 1

After Chaos absorbs one Chaos Emerald, Chaos has slightly changed. Chaos 1 increases in size and gains a line of "bones" that travel down its right arm into its hand, where the Emerald is located. As such the arm becomes bulkier. He briefly appears in *Sonic Adventure* after Sonic or Tails fights Eggman for the first time, and is never fought. Due to never being fought, his abilities are unknown. Knuckles also meets Chaos 1 in the Hotel room just before it transforms into Chaos 2.

#### Chaos 2

Chaos is much stronger after absorbing the two Emeralds. It is taller and more muscular. It has also developed new powers like a blue energy shield to prevent frontal attacks and the ability to transform into a huge ball, several small orbs, or waves of water.

#### Chaos 4

Chaos' shape is transformed to a shark-like water creature that can swim and dive into water. It can split itself into projectiles just likeChaos 2, however it is upgraded with new abilities to match the new form, including more control on water and nimble leaps that create waves of water toward the opponent.

#### Chaos 6

After absorbing six Emeralds, Chaos has changed dramatically once again. It is no longer even vaguely humanoid, but a scorpion/spider/frog-like creature. Chaos now commands more energy to empower his body, and also use his retained tail to smash opponents.

#### Perfect Chaos

After absorbing the negative energy of all seven Chaos Emeralds, Chaos will become a giant serpentine dragon-like beast with a mouth extending far beyond its eyes, which for the first time have pupils that resemble a reptile's. At the base of its snake-like body seems to be a huge whirlpool and cyclone. It has large tentacles extending from its base.

Perfect Chaos' new powers include creating small tornadoes, firing clusters of yellow and pink energy balls, and shooting a powerful energy beam from its mouth. It has complete control over water as Perfect Chaos is able to flood Station Square with ease.

## Theme songs

Chaos has a number of theme songs in the games that are attributed to itself. The genres of the songs vary.

* "Boss: Chaos ver.0, ver.2; ver.4" - plays during the battles against Chaos 0, 2 and 4. It is also used in Super Sonic's story summaries as there is an image of Perfect Chaos in the backdrop.
* "Boss: Chaos ver.6" - plays during the battles against Chaos 6.
* "Perfect Chaos Revival" - plays during the second half of the battle against Perfect Chaos. It also plays in *Mario & Sonic at the Olympic Winter Games* when Perfect Chaos appears.
* "Open Your Heart" by Crush 40 - plays during the first half of the battle against Perfect Chaos; shared as the main theme of *Sonic Adventure*. A cut-down, instrumental version is also used in *Mario & Sonic at the Olympic Winter Games*.
* A special song plays in the fight against Chaos 0 during the Story Mode of *Sonic Battle*. It has no name, but is number 18 in the Sound Test.

## TMNT X Pokemon

As one of the villains, you have to hit the chaos emeralds to count as a hit.

## Trivia

* In Greek mythology, Chaos was the name of the first deity to come into existence. It is described as vast and formless, much like the being from the *Sonic* series. According to Hesiod, Chaos was also the dark void from which the Earth goddess Gaia was born.
* Although Chaos first appeared in *Sonic Adventure*, he was briefly alluded to as early as the prologue in the manual for the Japanese version of *Sonic the Hedgehog 3*, where Knuckles speculated that the crashed Death Egg in the lake on Angel Island was the egg containing a legendary dragon that was fated to destroy the world.
* Because of positioning on the map, Big the Cat is able to come in contact with Chaos 4 prior to his battle with Chaos 6 by approaching the arena from the proper direction and jumping into it. This is the only time that directly touching Chaos does not harm a character.
* In *Sonic Adventure* and *Sonic Generations*, Chaos is translucent, but in all his other appearances he is opaque.
* Chaos 1 is the only seen form of Chaos not to have a boss.
* Chaos 1, 2, 4, and 6 have what appear to be bones, but Perfect Chaos does not have any. The bones are probably meant to hold the Chaos Emeralds in place until he has all seven of them.
* Chaos 3 and 5 are never seen, as Eggman gives Chaos the third and fourth emerald at the same time and he gives the fifth and sixth emerald to him off-screen.
* When the Chaos Emeralds are in Chaos, they look like a gradient color tint rather than their usual diamond design. Additionally, the emeralds that appear inside Chaos are rarely the same color as the actual Emeralds he has received; his second Chaos Emerald, the Gray Emerald, appeared Red once he had absorbed it.
* Chaos was purposefully created for *Sonic Adventure* to be a boss that would have been difficult to render on systems before the Dreamcast.
* In *Sonic Adventure 2*, Chaos is featured on several billboards. First, billboards advertising two fictional soft drinks (Chaos Cola and Chaos Soda) appear in several stages, such as Shadow's Radical Highway stage. Second, in City Escape and the Big Foot boss battle, Chaos 0 can be seen on billboards advertising a fictional movie named Planet of the Chaos, apparently based on Planet of the Apes. The movie is shown to be rated PG-13 by the MPAA.
* There is a special kind of Chao, called the Chaos Chao, whose head and limbs resemble those of Chaos 0.
* Chaos and Chaos Gamma are the only playable characters in *Sonic Battle* that do not have a story mode.
	+ They are also the only unlockable playable characters in *Sonic Battle*.
* According to an interview on Sonic Central, Sonic does not know the whereabouts of Chaos, Fang the Sniper, Bark the Polar Bear, Ray the Flying Squirrel, Bean the Dynamite, or Tikal.[15]

* Chaos appears as the final boss in the *Sonic the Hedgehog* Level Packof *LEGO Dimensions*. In this game, a giant Chaos 0 from another dimension attacked the Death Egg seeking the Chaos Emeralds, where it fought Sonic the Hedgehog until Sonic could go Super Sonic and defeat the beast.
