Mack

Personality
Mack is an UNSC A.I. on Harvest. His chosen avatar is that of a cowboy, exactly as those from spaghetti western movies. He is lighthearted and speaks in a southern drawl. He is in charge of all of Harvest's agricultural operations. These planetary operations include the control of the JOTUN harvesting devices which are used for planting, maintaining, harvesting and packing of agriculture on Harvest, as well as preparing the agriculture for it's journey up Harvests space evevators.

He works adjacent to a separate A.I., Sif, who is responsible for Harvests shipping operations, as well as the Orbital Space Station, Tiara and its seven space elevators.

Battle of Harvest
He often would playfully "flirt" with Sif, eliciting strange responses in the female AI, seemingly of hate but tinged with an unexplainable feeling analogous to human attraction underneath. Eventually he reveals to Sif that he is not one but two AI's, his counterpart being an A.I. known as Loki, the originally the A.I. of the UNSC Skidbladnir. As the Covenant press their attack on the planet, he gives over his control to Loki, transmitting "himself" into the thousands of JOTUN machines below. He instructs Loki to keep Sif safe, but Loki disagrees and believes it to be easier just to destroy her. Mack eventually rebels against Loki, resisting his attempt to activate a ground-based mass driver, an early, ground based version of the Magnetic Accelerator Cannon (MAC), which Loki was trying to use to destroy the Tiara, as well as Sifs data center so that she would not fall into the Covenants hands. Mack's final transmissions are extremely mysterious as the Covenant burn his world...he continues to resist, but as his resources dwindle he makes a last desperate attempt to help his now destroyed "love" Sif by burying her destroyed Space Elevators. He tries to "Bury your strands so deep their fires can't reach them \ \ and glass them like the rest". His final words are a misquoting of Shakespeare, a habit he had that annoyed Sif but created a bond between the two.
