Rtas 'Vadum



Special Operations Commander Rtas 'Vadumee, or "Half-Jaw", as he is known unofficially, for his name is not mentioned in Halo 2 at all, is a Sangheili with white or "Ultra" armor, as Cortana calls those of his rank. He is a Commander of Covenant Special Operations forces. He is mostly recognizible because he is missing his left mandibles, hence the fan-name, "Half-Jaw".

Biography
Rtas was present during the campaign against the Pillar of Autumn at Halo. He escaped before the ring was destroyed.

The Infinite Succor
When the Agriculture Ship Infinite Succor was boarded by an unknown threat, Rtas lead a team there to investigate, along with securing a Legate known as the Minister of Etiology. They encountered the Flood for the first time there. In an attempt the kill the Flood, Rtas used the Engineering station to set a Slipspace course to the Sun. During that time, it was revealed that the Legate had become infected, and Rtas had to battle an infected Kusovai. It was there that an Energy sword cut off his left mandibles. He managed to escape two minutes before the Slipspace Jump occured. He is believed to be the only survivor of the Infinite Succor mission.

The Heretics


He was assigned to hunt down the Heretic Leader on a gas mining platform over Threshold. Joining him was the Arbiter, recently sentenced by the High Council. Aboard a Phantom, he provided reinforcements to the Arbiter as he progressed through the facility. Eventually finding the Heretic Leader, they chased him into another part of the platform. Rtas got out and joined the Arbiter in his search on foot.

Rtas is reminded of his past by a familiar "stench", moments before running into a battle between the Heretics and the Flood. Clearing out the area of hostilities, they futher pursue the Heretic Leader until he locks himself behind an unbreakable energy barrier. Giving up, Rtas was about to turn away until the Arbiter asks for his energy sword so he could cut the cables, possibly drawing out the fugitive. Rtas agreed, giving his partner his prized possession. Leaving the Arbiter to his work, Rtas left for his Phantom.

Changing of the Guard


Back in High Charity, the Jiralhanae were taking over the position of Honor Guard to the High Prophets. Expressing his disdain to the Prophets of Truth and Mercy, Rtas was disgusted by this radical switch in tradition and customs. However, Truth refused to hear any more of it, and Rtas was sent away. As he left, Truth muttered to himself "Politics, how tiresome".

The Search for the Sacred Icon
Soon afterward, he was involved in the Covenant operations against the Flood inside the Quarantine Zone.Travelling in a Phantom, he and his squad set down and set up an encampment, which was soon after attacked by the Flood. Soon after, he met up with the Arbiter, in his search for the Sacred Icon, the key to make way for the Great Journey. Leaving the Arbiter on his own, he gained a Spectre and rejoined his friend later in the Quarantine Zone. They arrived at a massive gondola, which would take them into the Library, towards the Sacred Icon. He stayed behind to attack and draw off some Flood, allowing the Arbiter to obtain the Icon.

Deactivating Halo
Word got out that the Prophet of Truth had his hands on the Sacred Icon and the Oracle and was going to begin the Great Journey. Commandeering a Wraith, Rtas spotted a Scarab walker parked outside a Jiralhanae encampment. Meeting up with the Arbiter once again, they attacked the surprised Jiralhanae and met up with a squad of Lekgolo and other Sangheili. Rtas was left behind when the Arbiter escorted Johnson to the Control Room, it is unknown of what happened to him.

The Invincible Rtas
Much like Sergeant Johnson, Rtas is invincible throughout Halo 2.

Production Notes
"Half-Jaw" was voiced by Robert Davi on Halo 2.

The "Half-Jaw" model for Halo 2 was created by Marcus R. Lehto.

Rtas only appears during the following levels:
 * Halo 2
 * The Arbiter
 * The Oracle
 * Sacred Icon
 * Quarantine Zone
 * Uprising (Cutscene)
 * The Great Journey

Joyride Studios had originally planned to produce Half-Jaw Action Figures in the eighth series of the Halo 2 8-inch figures, but the production was cancelled because they felt it was pointless to release another Elite figure with a different paint job. Also, in light of the Halo 3 announcement, Joyride is hard at work producing figures for Halo 3. They did not feel that a Half Jaw figure was worth producing.
