Bugs are robotic probes used by the Machines to track a bluepill's location in the Matrix. They are placed onto a human subject's skin, where they will burrow underneath and take shelter inside the subject's body.

While activated they appear to be a small dark gray steel shrimp-like robot with wiry tentacles and a single red eye. However, once deactivated the squirming probe will appear to be back in a motionless steel probe and the red eye turns off.

Bugs can be removed from the host's body using an extraction device. The process is difficult and requires a fair amount of skill. When detected, the bug can simply move to a different position.


The bug burrowing into Neo’s Belly Button.

  • In The Matrix, after refusing to cooperate during interrogation by Agents Smith, Brown and Jones, Neo has a bug placed on his abdomen, which burrows into his navel. It is later removed by Trinity and Switch.

The bug being ripped out of Neo’s Belly Button.

  • Ash in the Animatrix short film "A Detective Story" has a bug planted behind his eye during what he believed was an eye examination dream which was removed by Trinity when he found her.


  • The scene where the bug enters Neo’s navel was intended as a rape metaphor, since Neo’s mouth is sealed shut and a phallic shaped object is forcefully penetrating his navel, with it representing an orifice. This however is not confirmed by the actual franchise creators.
