The Command Module is a device that Plankton makes to impress Karen, and to try to replace her. The module is seen in the episode "Komputer Overload."
The Command Module is an old dark blue hair dryer with an antenna taped to the back of a miniature light brown windmill with sharp blades that spin very fast. The hairdryer on it has a built-in flame-thrower.
Role in episode
The Command Module dislikes other robots and attempts to demolish them, but later, the robots combine into one robotic mayhem machine for Plankton to control, with the Command Module in the top section. At the end, since the giant robot is connected to a plug and eventually came closer to the Krusty Krab, the plug comes off. Thus, the robot topples and falls, leaving Command Module and the others destroyed, ending Plankton's evil plan to steal the formula.
The hair dryer should have fallen off since it was only taped and would be much heavier.
