Cell is a recurring enemy in the  . It is a miniature robot model developed by Sonic the Hedgehog series Professor Gerald Robotnik which is created when an Artificial Chaos P-100, an experimental cyborg model based on the ancient deity Chaos which roams the Space Colony ARK, divides its body mass.
Cells up close in
. Sonic Adventure 2
The Cells have the same configuration as their
parent, resembling blob-like orbs of water with a small mechanical helmet. Originally, Cells had a green light on their helmet, but in they have red lights instead.
Shadow the Hedgehog
Sonic Adventure 2
The Cells made their first appearance in
and its remake Sonic Adventure 2 . Being created from Sonic Adventure 2: Battle Artificial Chaos P-100s, they never appear without an Artificial Chaos to spawn them.
Sonic in . Sonic Adventure 2
When an Artificial Chaos P-100 spots the player in gameplay, its watery body will split into a certain number of Cells, leaving its mechanical head hovering in the air. The Cells will then attack by constantly crawling toward the player and explode on contact, often in large numbers. If the player attacks them, they will explode (causing the Cells around them to explode too) but will not hurt the player.
While the player can destroy each Cell manually, destroying the head of the Artificial Chaos that spawned them will destroy them all at once. Each individual Cell gives ten
points when destroyed, but no points are awarded per Cell if they are destroyed by the head being destroyed.
Shadow the Hedgehog
, Cells once again appeared exclusively alongside Shadow the Hedgehog Artificial Chaos P-100s, never once appearing by themselves.
In this game, Cells will emerge from the body of an Artificial Chaos P-100 when it is attacked, leaving its mechanical head hovering in the air. After floating around the head for a few seconds, the Cell will remerge with the head. Like in
, destroying the Artificial Chaos's head destroys all its Cells too, although the player can still destroy each Cell one by one. While destroying a Cell does not award Sonic Adventure 2 points, the Artificial Chaos P-100's body will be smaller when its remaining Cells remerge.
Powers and abilities
The Cells are capable of levitation and can detonate themselves to damage foes. Being formed from an
Artificial Chaos P-100's body mass, the Cells can remerge with themselves to reform their gestalt form's body.
The Cells rely on their Artificial Chaos P-100's head for commands. As such, they will be destroyed when their associated head is destroyed.
