Chaos

Chaos is a video game character and the main antagonist in the video game Sonic Adventure for the Sega Dreamcast. It also appeared in the first 11 episodes of Season 2 of Sonic X. Chaos is the first main antagonist of a Sonic game that is not Doctor Eggman. This eventually became common in the 3D games, with Eggman's role as the main villain being replaced by other villains (though often Eggman still makes an appearance). Chaos is an immortal, ageless god-like creature (referred to as the "God of Destruction" by Eggman) that seems composed almost entirely of water (save for his brain, green glowing eyes, and, in some later forms, bones) but is also said to be concentrated Chaos Emerald energy (in Sonic X, Doctor Eggman implies that it is composed of "Chaos energy in a liquid state"), however it has been revealed that Chaos is a Chao that came into contact with the Chaos Emeralds. It was trapped inside the Master Emerald for thousands of years before being released by Dr. Eggman in a bid to conquer the world. It was also the original guardian of the Chaos Emeralds, Chao, and the Master Emerald. In Sonic Adventure it absorbed the negative energy of the Chaos Emeralds to attain its final and strongest form.

Past
Chaos is a mutated chao that uses its power to guarantee clear water around the altar of the Master Emerald, and to protect its fellow Chao. However, the leader of the Echidna tribe, Pachacamac, tried to steal the Emeralds so he can use them against his enemies. His warriors storm the shrine where the Emeralds are kept, harming many Chao in the process. Chaos, in a fit of rage at seeing the Echidna tribe hurting the Chao, absorbs the negative power of the Chaos Emeralds and transforms into "Perfect Chaos". The resulting floods destroy the Echidna civilization. Pachacamac's daughter, Tikal, seals both Chaos and herself into the Master Emerald. It is from this point in history that the Emeralds are called "Chaos Emeralds".

Present (Sonic Adventure)
In Sonic Adventure, where Chaos is introduced for the first time, Dr. Eggman, having read ancient tablets describing the fall of the Echidnas and Chaos, releases it by shattering the Master Emerald in order to make the creature help him in his quest for world domination. Chaos swears to follow Dr. Eggman as it knows that he can get the Chaos Emeralds back.

Eventually, Eggman's plans, as always, fall through at the hands of Sonic the Hedgehog and his friends. Chaos abandons him and collects the Emeralds itself, absorbing the negative powers of them and transforming into Perfect Chaos again. This leads to the city Station Square's destruction as a result of the flooding. Having only taken the negative energy, Chaos discards the remnants of the Chaos Emeralds. This proves to be the means to its downfall as Sonic absorbs the positive energies of the Emeralds and transforms into Super Sonic, eventually defeating Perfect Chaos and in the process ridding Chaos of its evil mindset and turning it back to Chaos 0. Tikal's spiritual form then approaches Chaos, and together they disappear in a flash of light.

Sonic Adventure 2
In Sonic Adventure 2, Chaos Zero (the "zero" is spelled out in-game) is a secret character that can be unlocked by getting all A's in Rouge's missions. After that, it will be playable in the 2-Player Mode's "Treasure Hunting" stages. In Sonic Adventure 2: Battle, the game's enhanced remake for the Nintendo GameCube, Chaos Zero is an initially available character, and does not require unlocking.

Chaos Zero is a fairly slow character, but has powerful, long-ranged attacks. In this game, Chaos Zero can glide, climb and dig just like Knuckles and Rouge, and it also gains four new attacks: "Chaos Impact", a powerful ground punch that creates a small earthquake that trips the opponent and stuns him/her temporarily, "Chaos Strike", a blue energy pulse that harms and confuses enemies, "Chaos Bind", a move which freezes the air around the enemy and immobilising them for 30-40 seconds, and "Chaos Screw", in which Chaos spins upwards in the air while extending its arms. Unlike other characters in this game, Chaos Zero can't drown, being composed of water itself.

Sonic Battle
Chaos's latest appearance is in Sonic Battle, where Knuckles claims that Chaos only appears in times of great crisis. When Dr. Eggman threatens the Earth with his Death Egg in the final story, a nearby volcanic crater is flooded and freezes over, and Chaos emerges as Chaos 0. It can then be challenged by the player, and defeating it (with Emerl) unlocks it as a playable character for Battle and Challenge modes. It also has a number of skill cards that Emerl can learn.

Chaos 0 is the slowest character in the game, but its extendable limbs give it a much wider attack range than it appears to have, and it is very powerful. Some of his combos can KO an opponent instantly. It can turn into puddle of water as usual, and can create fountains, tentacles, and orbs of water to fight.

Chaos's forms
Chaos' form and skills change and increase with every Chaos Emerald that it absorbs. Over time it develops from a humanoid water creature to a horrible, world-destroying monster. The names for the various forms are generally "Chaos" followed by the number of Chaos Emeralds inside it, with the exception of its final form. The forms presumably called "Chaos 3" and "Chaos 5" are never shown in Sonic Adventure due to the circumstances of absorbing two Emeralds at once in two different instances, causing it to skip these two forms.

It is implied that Chaos has a tail. The tail is somehow connected to Big the Cat's pet Froggy. The tail is never shown until "Chaos 6", because that is when Eggman lets Chaos absorb Froggy (that he stole from Big).



Chaos 0
This is the base form of Chaos before it has absorbed any Chaos Emeralds. It is humanoid, and about 150 cm (five feet) tall with bright green eyes. Its brain is visible in this form through its watery exterior. Sonic Adventure begins with Sonic fighting Chaos 0 outside the City Hall in Station Square. Its attacks include extending its arms to punch, spinning around with its arms extended and jumping high and quickly onto light posts in order to get out of Sonic's range.



Chaos 1
After Chaos absorbs one Chaos Emerald, it becomes taller and has a line of bones that travel down its right arm into its hand, where the Emerald is located. As such, the arm becomes bulkier. This form briefly appears in the Mystic Ruins in Sonic Adventure after Sonic or Tails fights Eggman for the first time. Chaos 1 is never fought, only briefly appearing in cut scenes. Due to this, its abilities are unknown. Some of its abilities were shown in Sonic X only shortly. Knuckles also meets Chaos 1 in a hotel restaurant just before it transforms into Chaos 2.

Chaos 2
Chaos is much stronger after absorbing two Emeralds, becoming taller and more muscular. The bones Chaos 4.



Chaos 4
Chaos changes considerably after absorbing four Chaos Emeralds. It is now a huge shark-like creature with razor-like fins. It fights Sonic, Tails and Knuckles in a small pond in the Mystic Ruins, but is defeated. Its new powers include being able to fire energy waves, swimming at high speeds, creating water explosions, and turning into four balls that bounce toward the player. If Chaos 4 is out of water it simply floats in the air. The third and fourth Emeralds Chaos absorbed are now located in its belly. Big the Cat encounters Chaos 4 just before it transforms into Chaos 6.



Chaos 6
After absorbing six Emeralds, Chaos has changed dramatically once again. It is no longer even vaguely humanoid, but a 7.5 meter (25 foot) tall scorpion-like creature. It also has eight or more eyes, a bulldog-like head and a mouth filled with razor sharp teeth. Its tail is tipped with a pendulum-type blade. Unlike its previous forms, Chaos 6 cannot be injured by attacking its head, as the brain is too deeply situated to be damaged. Instead, Chaos 6 can only be damaged by freezing and shattering its liquid body. Both Sonic and Knuckles fight Chaos 6 on the Egg Carrier after Big the Cat fishes Froggy out from inside Chaos. Chaos's new powers include creating powerful shock waves and trying to inhale enemies to absorb them. It can also make dozens of spikes stick out of his body and smash enemies with its huge tail. The Emeralds it absorbed are now all around its body.



Perfect Chaos
After absorbing the negative energies of all seven Chaos Emeralds, Chaos has become a god of destruction. It has become a giant kraken-like beast with a mouth extending far beyond its eyes, which for the first time have pupils that are thin and resemble those of a reptile's. At the base of its snake-like body seems to be a huge whirlpool or cyclone. It has large tentacles extending from its base. Perfect Chaos's new powers include creating small whirlpools, firing clusters of yellow and pink energy bolts, and firing a huge energy beam from its mouth. It is the final boss of Sonic Adventure, where only Super Sonic has the power to take it down. In its Perfect form, Chaos is quickly able to shoot down Eggman's massive Egg Carrier 2, an exact remake of the original Egg Carrier, that was built as a fail safe in case Chaos rebelled. One noticeable fact about Perfect Chaos is the significant resemblance between him and the Godzilla monster Biollante from the 1989 film.

Artificial Chaos
Artificial Chaos are semi-robotic enemies that appear in Sonic Adventure 2 and Shadow the Hedgehog. The latter explains that the renowned scientist professor Gerald Robotnik had built them as experiments, and based them on "a god of an ancient culture", quite obviously meaning Chaos. After being created roughly 50 years prior to the games, the experiments went out of control and started attacking everyone in sight.

In Shadow the Hedgehog, Shadow himself appears to have a flashback to his time on the Space Colony ARK, during the time when the Artificial Chaos went out of control. In the flashback level, the player can choose to find and destroy all 35 experimental Artificial Chaos, or simply stay away to make sure the professor is safe. Either way, the experiments survive, as they appear in Sonic Adventure 2 as common enemies that protect the ARK. In the level "The ARK" in Shadow the Hedgehog, the villain Black Doom states that "they are ours now", suggesting that the Black Arms somehow took control of the Artificial Chaos. They also make a very minute appearance in the "Cosmic Fall" level, and are not mentioned by either Vector or Black Doom.

The Artificial Chaos appear as mechanical heads shaped like that of Chaos 0, towering on top of a large pillar or orb of water-like material. The pillar-shaped Artificial Chaos usually do not move, although they can turn in place. The orb-shaped Artificial Chaos float somehow in mid-air and they are mobile. All Artificial Chaos can only be destroyed by hitting the mechanical heads; hitting the water portions will cause the player to merely bounce off. They exist in (at least) two different versions; P-1 and P-100. P-1's fight by stabbing their enemies with quick, extremely accurate tentacles of water, or by firing laser beams from their green eyes. Some Artificial Chaos seem to lack any intelligence or aiming abilities at all, and simply spin around, shooting lasers in random directions.

P-100 Artificial Chaos can split their bodies into dozens of small drones (known as Cells) that are controlled by the floating robotic head, but are not armed with lasers. These drones constantly edge their way toward the player and explode on contact. If the player attacks them, they also explode (also causing the Cells around them to explode in a chain reaction) but they do not hurt the player. After releasing its Cells, the Artificial Chaos head simply floats, defenceless, in mid-air until it is destroyed. It should be noted that if the Artificial Chaos head is destroyed, all of the drones explode.
