The Artificial Chaos P-1 (人工カオス Jinkou Kaosu?) are robotic enemies that appear in Sonic Adventure 2 and Shadow the Hedgehog.

While they don't appear in it, the latter game explains that the renowned scientist, Professor Gerald Robotnik, had built the Artificial Chaos series 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.


The Artificial Chaos are generally large pillars of water, with a mechanical head shaped like Chaos 0's towering on top. P-1s fight by stabbing their enemies with quick, extremely accurate tentacles of water, or by firing lasers from their green eyes.


Artificial Chaos P-1s appear 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, P-1s 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.

Powers and abilities

P-1 Artificial Chaos are capable of firing lasers from their eyes and can extend tentacle-like stretches of water from their bodies, much like Chaos 0 itself. Some P-1 seem to lack any intelligence or aiming abilities at all, and simply spin around while shooting lasers in random directions. They are also capable of clinging onto ceilings and other surfaces thanks to their body being made of water, and can also hide their robotic head within their bodies to protect themselves


Artificial Chaos P-1 has two sub-types of which have different attack patterns. P-1 appear in Tails and Eggman sections of Cannon's Core.

Guard Type P-1

The Guard type are standing Artificial Chaos that can only fire lasers from their eyes, and cannot retract their heads or use tentacles to attack the player.

Float Type P-1

These Artificial Chaos would float in midair with its water-part shaped as a large sphere, making these types resemble the P-100 series. 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 their normal variants.


  • 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.
  • 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.
  • Despite being mentioned in Sonic X anime, the Artificial Chaos did not make an appearance.
