Zim's Computer is the artificial intelligence that controls Zim's house and base; essentially, it is his entire base. It was voiced by the series creator, Jhonen Vasquez. In the Spanish dub, it was voiced by Víctor Delgado.


The computer is highly advanced in its ability to communicate with others, often choosing to speak in a more casual tone. Although the computer often gives its master advice, Zim usually ignores it, even shouting out "I don't pay you to contradict me!" in "Walk for Your Lives", to which the Computer responded with "You don't pay me at all!". It often becomes very exasperated with Zim, occasionally ignoring him, being sarcastic or blatantly refusing to perform any actions for its master. On some occasions, it will hold information from Zim, such as in "Backseat Drivers From Beyond the Stars", when the Computer casually blurted out, "P.S.; I've located an alien monitoring device within the base." In the cancelled episode "Nubs of Doom", the Computer flatly said "I don't want too!" when Zim demanded it bring him ear plugs. Sometimes instead of responding to Zim's harkening with its actual voice, it will reply with a few small beeps.

The computer is prone to defects, as seen in "Invasion of the Idiot Dog Brain". When the computer is proven to be defective, the Artificial Intelligence Brain is replaced with a new one. The Brains resemble human brains, and are plugged into the center of base, after which the new AI flows through data conduits. However, the computer seems to be functional most of the time, save for a fit of unexplained coughing in "Walk for Your Lives". Unlike GIR, the Computer is everything but dysfunctional. However, it gets annoyed with its master frequently.
