Artificial Chaos P-1

Artificial Chaos 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", which is, of course, Chaos. After being created, the experiments went out of control and started attacking anyone in sight.

In Shadow the Hedgehog, 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. In any case, the experiments were subdued, and it seems they were perfected as they appeared in Sonic Adventure 2, where they protected the Space Colony ARK. In the stage "The ARK" in Shadow the Hedgehog, Black Doom states that "they are ours now", suggesting that the Black Arms somehow took control of the Artificial Chaos.

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-1:s 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, shooting lasers in random directions.
