Loki was a Planetary Security Artificial Intelligence construct in service with the United Nations Space Command. He was stationed aboard the Phoenix-class Colony Ship, UNSC Skidbladnir until it landed on Harvest.

Avatar and Role

Loki and Mack actually shared the same data center and processor; however, only one could use it at any one time. Mack showed Sif that in his data center, he had two matrices (it is assumed that one is for Mack and the other is for Loki). When the swap was needed, Mack would send the relevant data to Loki's matrix before Loki assumed control of the data center (and by extension everything Mack had influence over on Harvest). Besides a few minor variations of the avatar, mainly the eye color (Mack's eyes were gray, Loki's were red) and cleanliness (Loki's avatar was clean whereas Mack's was dirty from "working in the field"), they looked the same.

Biography

When the Tiara was boarded by Covenant forces, Sif sent a distress signal intended for Mack. However, by that point Loki had already switched places with Mack. Mack had told Loki to keep Sif safe; however, Loki believed it would be better to destroy Sif to protect all other human colonies. He unleashed a powerful virus upon Sif that purged her code throughout all her clusters save one, which he kept operational to monitor the invaders. When Lighter Than Some began repairing the Tiara's data center, he found Loki's fragment and they developed a makeshift plan to lure the Covenant warship Rapid Conversion in range of the planet's mass driver. Loki succeeded in executing the plan, disabling the warship and commencing the evacuation of Harvest's surviving population. However, he hadn't anticipated a counter-assault by the Covenant, and was saved only by Mack, who was inhabiting the JOTUNs. However, Loki's data center was damaged by a spike grenade, weakening him.

Mack then turned on Loki, using his JOTUN "all-in-ones" to hack the MASER dish and destroy Loki's fragment in the Tiara (his attempt to protect what little was left of Sif). During the evacuation, Loki, in his weakened state, was unable to rebalance the Tiara's load after the collapse of the number seven strand, but he received help from a rampant Sif who had been repaired enough by Lighter Than Some that she was able to help complete the job. After the evacuation was complete, Loki sought to finish the job he had started (destroying Sif) but was once again faced with stiff resistance from Mack's army of JOTUNs. However, Mack did concede to Sif's agreement that her destruction was the best thing for humanity, and Loki fired a mass driver round directly into her data center, completely obliterating her.

The full details of the nature of Loki's own destruction are not known; Mack later does reveal that Loki was destroyed in an explosion that consumed Harvest's reactor (which housed Mack/Loki's data center). From Mack's transmission though, the reactor went critical, possibly due to the firing of the mass driver twice in quick succession again which Loki had to work hard to keep from causing an overload the first time and in his weakened state, may not have been able to prevent a second time. Also he may have chosen to destroy himself like he did with Sif in order to prevent the Covenant from getting their hands on him.

Trivia

• Loki is named after the god of mischief in Norse Mythology. He was an adept shape-shifter and could change not only his form, but also his sex, possibly referencing the ability to switch between himself and Mack. In Norse Mythology, he usually plays the role of villain and trickster.
• There is a group of structures called "The Pillars of Loki", which could be a reference to him.
• Loki seems to be the only AI with two different personalities; those of himself and Mack.
• The ship Loki served on, the Skidbladnir, it is also a reference to Norse mythology. It was the name of a ship which Loki requested to be made for Freyr, in preparation of the theft of Sif's golden hair.
