Summary
High-ranking Covenant Elite stationed on Installation 04 in 2552. After the Pillar of Autumn was shot down, and First Lieutenant Melissa McKay conducted a salvage operation of supplies in the ship, 'Ontomee was put in charge of the crash site to make sure the Humans could not access it anymore.
During the final days of the Installation, 'Ontomee and his overworked and undermanned staff received fortunate relief in the form of Zuka 'Zamamee (under the Alias of Huki 'Umamee) and Yayap. Without asking questions, 'Ontomee put them in charge of twenty Jackals and assigned to inspect and unload supplies.
Under attack from both Flood and Forerunner constructs, 'Ontomee and his staff are further troubled when the Master Chief arrives on board the ship with the intention of destroying the entire Halo. 'Ontomee calls a meeting of his staff where he, 'Kasamee, and 'Zamamee discuss the Master Chief. 'Zamamee agrees to hunt him down, to the relief of 'Ontomee.
In all liklyhood, he is killed when the Autumn's fusion generators explode.
NOTE: 'Ontomee likely has a first name as most Elites do, but it is never mentioned.
Rank
'Ontomee's rank is never mentioned, nor is his official title, but the fact that 'Kasamee, a Major Elite, as well as 'Zamamee, a SpecOps Elite, are subordinate to him, indicate that he is likely either a Zealot or Ultra grade Elite. Since the only Ultra Elites on Installation 04 were killed on the Truth and Reconciliation after it was infested by the Flood, it is likely that he was a medium-rank Zealot.
