Jak
From Halopedia, the Halo wiki
Template:Ratings Template:Covenant Character Infobox Jak, was a Covenant Jackal stationed aboard the Pillar of Autumn crash site during the events on Installation 04. After a raid by the ODSTs led by First Lieutenant Melissa McKay, he was assigned to inspect and haul cargo coming into the crashed vessel for use by the Covenant who occupied it. This was to make sure that Flood did not infiltrate the vessel.
He was placed under the command of Yayap, after the Grunt arrived at the site following a failed battle at Alpha Base. He did not like the Grunt, calling him a "Gas Sucker." Nevertheless, he complied with Yayaps orders because he had no choice. He, along with Bok and Yeg tried to make Yayaps life difficult, nonetheless.
After Bok was killed by a group of Flood hiding in a cargo pod, Jak suddenly became much more respectful of the Grunt. It is unknown, what happened to Jak although it's highly that he was killed when the Master Chief detonated Installation 04.
