Chaos


 * This article is about the organism composed of chaos matter. For the gems, see Chaos Emeralds. For the small creatures, see Chao.

Chaos (Japanese: カオス) (also known as Chaos Zero) is the main antagonist in the video game Sonic Adventure for the Sega Dreamcast. Chaos is an immortal, ageless god-like creature that seems to be composed entirely of water (coincidentally Sonic has a weakness of water), 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"). 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
FKKKK YOUHHH DUUUUUDEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

YOU SOILED IT!! SOILED IT SOILEDDDD ITTTTTTTT!

I HATE YOU PEENUS

Sonic Heroes
Chaos did not appear in Sonic Heroes, but was mentioned in 2 lines, at the ending of Team Rose's story, when Froggy and Chocola are rescued, Metal Sonic says: "Chaos data...has been copied." At the final story, where Dr. Eggman says, "It's hopeless! Metal Sonic has combined your data with the power of Chaos and is super strong!" He copied Chaos' data from Big's frog, Froggy since he was "possessed" by Chaos's tail, along with Chocola the Chao, since all chao have some kind of relation with Chaos.

Sonic Battle
Chaos' next appearance is in Sonic Battle, where Knuckles the Echidna claims that Chaos appears when there is an upcoming disaster. When Dr. Eggman threatens the Earth with his Death Egg in the final story, a nearby volcanic crater is flooded, and Chaos emerges. It can then be challenged by the player. Chaos is the strongest playable character in the game (minus Emerl as he is customizable), but also by far the slowest.

Sonic Chronicles: The Dark Brotherhood
Chaos did not appear in Sonic Chronicles: The Dark Brotherhood, but was mentioned in one line, when Knuckles realized that Shade was an echidna. He said that Perfect Chaos flooded an ancient city and killed several hundred echidnas that resided there.

Mario and Sonic at the Olympic Winter Games
Chaos appears, as Perfect Chaos, in Mario And Sonic At The Olympic Winter Games as an obstacle in Dream Figure Skating (Sonic World). He also appears in is normal form as a VIP character that will sometimes send you letters and as a sticker.

Sonic Generations
Chaos will reappear in Sonic Generations, as a returning boss. It is unknown if Modern Super Sonic, Classic Super Sonic, both Super Sonics, or no Super Transformations at all, will battle him. He also makes a cameo in City Escape, along with the famous Chaos in Space 2.

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.



Chaos 0
This is the base form of Chaos before it has absorbed any Chaos Emeralds. It is humanoid, and about 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.

In Sonic Adventure 2, Chaos Zero (as it is called 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 as a treasure hunter in 2-Player Mode. In this appearance, it is significantly smaller than its prequel's counterpart, and its moves are all based on Rouge's. In Sonic Adventure 2: Battle, Chaos Zero is an initially available character. In this version, it is a very slow character, but has powerful attacks. It also cannot jump very high, which is in stark contrast to the prequel. In this game, Chaos Zero can glide, climb and dig just like Knuckles and Rouge, and it also gains three new attacks: Chaos Impact, a powerful ground punch that creates a small earthquake, Chaos Strike, a blue energy pulse that harms and confuses enemies, and Chaos Bind, a move which freezes the air around the enemy for 30-40 seconds. Chaos Zero is also able to swim underwater for an unlimited amount of time.

After Chaos appears in Sonic Battle, Emerl can challenge it and copy its abilities. After the player defeats Chaos, it is unlocked as a playable character in Battle and Challenge modes. In-game, Chaos can barely jump and is incredibly slow but its extendable limbs give it a much wider attack range than it appears to have, and it is very powerful. It can turn into puddle of water as usual, and can create fountains, tentacles, and orbs of water.

Chaos 1


After Chaos absorbs one Chaos Emerald, it is virtually unchanged except for 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 two Emeralds. It is taller and more muscular. The bones that were in Chaos 1's right arm now run along both of Chaos 2's arms and now both hands have Emeralds. Its head has moved forward, giving it a more unpleasant appearance, the horns on his head have also changed position to give it a hammerhead style look. 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. Knuckles the Echidna fights it in the Hotel Restaurant in Station Square. Sonic, Knuckles and Miles "Tails" Prower later meet Chaos 2 by the pool of water in the Mystic Ruins just before it becomes Chaos 4.

In Sonic X, Sonic and Knuckles fight Chaos 2 together right after Sonic defeats Chaos 0. In this version of the fight, Chaos sprays water from his hands and has a near-unbreakable shield of electrical properties.

Chaos 3
This form is never seen in the game due to the fact that Chaos 2 had absorbed 2 more Chaos Emeralds at once, skipping this stage and moving to 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 on the Egg Carrier just before it transformed into Chaos 6. Interestingly, even though Chaos' tail is absorbed by Froggy at the time being, Chaos 4 still sports a tail in which he can use for attack, so it may actually have two tails.

Chaos 5
This form is never seen in the game due to the fact that Chaos 4 had absorbed 2 more Chaos Emeralds at once, skipping this stage and moving to Chaos 6, although lacking its tail.

Chaos 6


After absorbing six Emeralds, Chaos has changed dramatically once again. It is no longer even vaguely humanoid, but a twenty-five foot tall scorpion/frog-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. (Interestingly, in Sonic X, Sonic and Knuckles work together to defeat Chaos 6, with Knuckles scooping away Chaos' body with Shovel Claw, and Sonic spin dashing straight through the exposed brain.) 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 and Big the Cat fishes Froggy out from inside Chaos. Chaos' new powers include creating powerful shock waves and trying to inhale enemies to eat them. He can also make dozens of spikes stick out of his body and smash enemies with his 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 will become a giant snake-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 fireballs, and firing a huge energy beam from its mouth. It has total control over water as Perfect Chaos is able to flood Station Square with ease. It is the final boss in Sonic Adventure, where only Super Sonic has the power to take it down. In its Perfect form, Chaos was quickly able to shoot down Eggman's Egg Carrier 2, which was a failsafe in case Chaos rebelled.

In Sonic X, Perfect Chaos looks more like the Loch Ness monster due to an increased "back" size and several new tentacles. Perfect Chaos also uses a few more powers, like absorbing projectiles like a sponge and then spitting them back at the attacker through its mouth, using its tentacles to attack (he is seen splitting skyscrapers in half with them), and creating crystal spires and an energy shield. He also controls water and, if you look closely before his battle with Super Sonic, his tongue is much longer than his enormous jaws. He can also fire an energy beam, which he uses to burn the Egg Carrier 2 to cinders.

It should be noted that Perfect Chaos' energy beam has an uncanny resemblance to Godzilla's Atomic Ray and that Perfect Chaos himself looks like Godzilla's rival Biollante. Also the fact that it destroyed a city may have led Sonic Team to giving it resemblances to kaiju. It is said that Perfect Chaos is Chaos' negative super form. In the Sonic X comic book, in which it absorbed the positive energy of the emeralds to take down Eggman's mecha, Chaos' positive super form simply looked like an over sized version of Chaos 0 with the seven Emeralds in its forehead.

Personality
Before Tikal's father and his soldiers came to the place where Chaos and the Chao lived and guarded the Chaos Emeralds, Tikal described Chaos as a very loving and gentle creature, being very protective of the Chao and possibly Tikal. 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 collect the Chaos Emeralds and destroy Station Square. However, when Super Sonic neutralized him, he turned back to his former self and was joyful to see that there were still Chao in the world.

Artificial Chaos
Artificial Chaos are robotic enemies that resemble Chaos. They 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", although he cannot have had access to Chaos itself when he created them.

After being created, the experiments went out of control and started attacking anyone in sight. As seen in flashback from Shadow the Hedgehog, Shadow himself fought Artificial Chaos on Space Colony ARK. They were eventually subdued, and by the events of Sonic Adventure 2 they were protecting the colony. Later still, they were taken over by the Black Arms and battled Shadow again.

Associated 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 0, 2, 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 when you fight Chaos 0 during the Story Mode of Sonic Battle. It has no name, but is number 18 in the Sound Test.

Sonic the Hedgehog Comics
The Sonic the Hedgehog comics echoed the Sonic Adventure storyline, with a number of variations. Chaos and Tikal were both imprisoned in a Black Emerald, which was broken open by a hammer wielded by Dr. Robotnik. This continuity also featured the Freedom Fighters, who assisted Sonic and Knuckles in the victory over Perfect Chaos.

Sonic the Comic
In the UK Sonic the Comic comics published by Fleetway Editions, Chaos is depicted as a much more intelligent and evil beast. Rather than being captured within the Master Emerald, Chaos was actually imprisoned by the Echidnas in a mystic container of some sort (showed fairly briefly). Robotnik somehow got a hold of this container, but never unleashed Chaos from his prison. However, his assistant Grimer released him when he saw that Robotnik was depressed after losing to Sonic so many times. The plan was that Chaos would devastate the planet and Robotnik would, in exchange for being made leader, use his old Chaos Nullifier device to defeat the monster. Unfortunately, Grimer hadn't realized that the Nullifier didn't work and thus Chaos couldn't be stopped...

In the comics, Chaos has a "fear factor" that instills anyone near him with incredible fear when they are around him, to the point where they fall to their knees petrified, though Sonic was able to resist this ability by focusing on his anger and rage. Unlike in the game, in the comic Chaos can talk (though in his first attack he seemed little more than a beast) and is actually a transformed Prosecutor of the Drakon Empire, transformed by Chaos Energy back during the ancient war between the Drakons and the Echidnas.

Chaos attacked the Floating Island in order to absorb the Chaos Emeralds, regaining his intelligence as he came into contact with them; Knuckles was forced to jettison the Emeralds, this sacrificing the Island, and the Freedom Fighters tried to locate them before Chaos could. Unfortunately, Robotnik - attempting to bring about Mobius's destruction - deliberately set things up so they couldn't trace the Emeralds and Chaos would get them all first. The creature transformed into Perfect Chaos (which resembled Chaos 6 from the game). Eventually Super Sonic (who at this point in the comic was separate from normal Sonic) absorbed all of Chaos's energy and Chaos reverts back to his fish state.

The fish was contemptuously thrown by Super into a river to be eaten by local predators, with Big the Cat looking surprised by the sight. Writer Nigel Kitching had planned to use the two characters as a double-act if the comic had continued, with Chaos trying to use an oblivious Big in order to contact the Empire. This idea would be recycled for the "unofficially official" continuation, Sonic the Comic Online, with Chaos (renamed "Buddy" by Big) trying and failing to regain his powers with Big's help; after two failures to regain his power, the Drakon ended up in a fish-tank and the mascot for Big's restaurant "Buddy's Bistro".

Nigel's original plan had Chaos as an ancient leader of the Drakon Empire, leading them against the echidnas. The Chaos Emeralds were special containers used to drain Chaos' powers from him, leaving him in a weakened state to be imprisoned. The final three issues would have featured a renewed Chaos summoning an army of Sentinels and the heroes having to prevent the wider Drakon Empire knowing Chaos had returned.

Nigel Kitching has said that the idea to give Chaos a 'fear factor' was to make him a little different (in particular to differentiate him from another STC villain, Megatox, who was also made out of liquid ) as well as making him interact with his enemies in a certain way.

Sonic X (anime)


The Sonic X anime follows the plot line of Sonic Adventure in episodes 27-32, resulting in Chaos's presence in those episodes in several of his many forms. However, Chaos's origins differ in the fact that it is described as "liquid Chaos energy" rather than the "God of Destruction".

Sonic X (comic)
Chaos first appears in the issue #5 in Cream's flashback. He later reappears in the issue #6, along with Tikal and an army of Chao, because the earth was in danger from Dark Chao and assisted Sonic to defeat them. He later defeats Eggman's robot with the help of the seven Chaos Emeralds (he did not transform into Perfect Chaos but was referred to a purified version of that form). When Eggman is defeated, he returns to his time with Tikal and the Chao.

Chaos then reappeared in issue #28 and #29. At the end of issue #28, once Dr Eggman collected the 7 chaos emeralds, thanks to his 'green bots', he used the master emerald and the chaos emeralds to recreate Perfect Chaos. Dr Eggman's green bots formed themselves in Perfect Chaos' chest so that Dr Eggman would have control over Perfect Chaos.

Issue #29 continued the story as Perfect Chaos being too powerful to stop. Dr Eggman used Perfect Chaos to attack Station Square again. Sonic reminded Chaos to fight his control, in which Chaos remembered his life with the Chao. He spat out the Chaos Emeralds, not using his form because of the green bots, and gave them to Sonic. Sonic used to the Chaos Emeralds to become Super Sonic, but was no match for Perfect Chaos who now also had the powers of Chaos Control and being under Eggman's power. After destroying Eggman's controller that controlled the green bots, Perfect Chaos attacked him. Super Sonic blasted through the green bots, destroying them. Chaos returned to Angel Island to go back into the Master Emerald.
