Zim's Computer

Zim's computer is the artificial intelligence that controls his entire base and Irken ships. Communication-wise, the computer is highly advanced, and yet sarcastic and casual in tone, often driven to annoyance with his master. On the one hand, the computer loyally and successfully imprisons Dib after Zim's abrupt departure in "Dimension Mix-Up"; on the other hand, the computer finds himself assisting Sonic in his efforts to escape from Zim in "Dimension Takeover," prior to the  War on Xevious —much to Zim's chagrin. Most likely, it is the same computer A.I. that speaks to the Tallest as they are escaping from Zim during the Scattering of the Irken Armada, judging by the equally casual and sarcastic tone.
