The Artificial Chaos (人工カオス Jinkou Kaosu?) are 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", although he cannot have had access to Chaos itself when he created them. When they were first created they began acting out and attacking the ARK (according to Gerald in Expert Mode, they had their electrode conductors reversed), but G.U.N. stopped them. They were later fixed, and then adopted briefly by the Black Arms and later by government to protect the ARK.

Game Appearance

Sonic Adventure 2

Artificial Chaos makes its first appearance in Sonic Adventure 2 as one of the main enemies at Crazy Gadget, Final Rush, Eternal Engine, Meteor Herd, Final Chase, Cosmic Wall, Mad Space, and Cannon's Core, as all levels take place on inside or outside of Space Colony ARK.

In the game, as the experiments were subdued at Space Colony ARK fifty years ago, Artificial Chaos are left to the colony as still being active. It seems they were perfected as they appeared in Sonic Adventure 2, where they protected the Space Colony ARK against intruders.

Shadow the Hedgehog

Artificial Chaos reappear in Shadow the Hedgehog, which has heavy connection to Sonic Adventure 2, story wise. Only P-1 types of Artificial Chaos appear in the game. Shadow himself appears to have a flashback to his time on the ARK, during the time when the Artificial Chaos went out of control. In the flashback stage, the player can choose to find and destroy them all, or simply stay away to make sure the professor is safe.

When the Black Arms invade the ARK, Doom's Eye calls the Artificial Chaos "the legacy of Gerald." At the stage The ARK, Black Doom states that "they are ours now", suggesting that the Black Arms somehow took control of all Artificial Chaos. They also appear in the Cosmic Fall level, attacking G.U.N. robots. They are the only enemies that can't be destroyed by the Shadow Rifle with one hit. However, they can be destroyed with one hit using bomb-type weapons.


Physical appearance

The Artificial Chaos are generally large pillars or floating orbs of water, with a mechanical head shaped like Chaos 0's towering on top. They exist in two different versions; P-1 and P-100. P-1s fight by stabbing their enemies with quick, extremely accurate tentacles of water, or by firing lasers from their green eyes. P-100 Artificial Chaos can split their liquid bodies into dozens of small blue 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 do explode (also causing the Cells around them to explode) but they do not hurt the player. After releasing its Cells, the Artificial Chaos head simply floats, defenseless, in midair until it is destroyed. Some Artificial Chaos seem to lack any intelligence or aiming abilities at all, and simply spin around while shooting lasers in random directions.


There are two primary different variants of these enemies Artificial Chaos P-1 and Artificial Chaos P-100. Artificial Chaos P-1 also has three sub-types of which have different attack patterns. P-1 appear in Tails and Eggman sections of Cannon's Core while P-100 also appear in Sonic's section of same level

Artificial Chaos P-1

Artificial Chaos2

Artificial Chaos P-1

These Artificial Chaos, which are believed to be the first prototype of the series (hence the name), are tall, stationary, and are able to pull their head into its body to protect itself. They had the ability to cling to any surface and attacked using either a laser built into its eyes, long tentacle-like extensions from its body, or a combination of both.

Float Type Artificial Chaos

These Artificial Chaos would float in midair with its water-part shaped as a large sphere. It either waits for someone to come within range, or floats toward them in the air. They attack with the same tentacles and lasers as the normal one.

Artificial Chaos P-100

Artificial Chaos1

Articificial Chaos P-100

This type of Artificial Chaos, which are believed to be the final prototype for the Artificial Chaos line (hence their name), have the ability to split up the nanobots that make up its body into dozens of smaller robots called "Cells". This, however, left the head open to attack and easy to destroy. When the head was destroyed, all the Cells that it spawned would self-destruct. These are also believed to be the version that Shadow destroyed when they ran amok on the ARK, though they acted a bit different, as they attacked with tentacles and only split up when damaged. In Shadow the Hedgehog, they can also grow to immense sizes, possibly by fusing with each other (several G.U.N. soldiers suggest this during the attack).

Artificial Chaos Cell


A Cell in Shadow the Hedgehog.

When the Artificial Chaos P-100 splits its body up, the pieces turn into small blob-like cyborgs that are referred to as its "cells". In Sonic Adventure 2, the cells would crawl on the ground and try to surround the player, at which point they would start to self-destruct. In Shadow the Hedgehog, they would emerge from the body of the Artificial Chaos P-100 when struck and float around the body for a few seconds before re-merge with the head. The cells will all be destroyed when the head is taken out.


  • In the original Dreamcast version of Sonic Adventure 2, their liquid bodies had a transparent effect. In Sonic Adventure 2: Battle, the transparency effect was removed, making them appear to have a more "solid" appearance. The Artificial Chaos experiments in Shadow the Hedgehog are more similar to their Dreamcast counterparts.
  • In Sonic Adventure 2, Artificial Chaos have a very good accuracy. A tip to avoid being hit is to be behind them.
  • According to Gerald's statement in Shadow the Hedgehog on Expert Mode in Lost Impact, the reason the Artificial Chaos became hostile was because Gerald Robotnik accidentally reversed the positive and negative electrode connectors within them. This created a problem in their programming and resulted in their hostility.
  • In Sonic Adventure 2, their bodies were indestructible and cannot be damaged except their heads, however in Shadow the Hedgehog, they can be destroyed in any spot in their bodies.
  • The P-100 series bears a great resemblance to Chaos 2 as both of them can separate themselves into pieces and make their brains float in mid-air.
  • Despite being mentioned in Sonic X anime, the Artificial Chaos did not make an appearance.
