Rtas 'Vadum (Earth-2356)

Rtas 'Vadum, nicknamed Half-Jaw, is a male Sangheili commander who served the Alliance to Restore the Republic and the Swords of Sanghelios. He is one of Arbiter Thel 'Vadam's right-hand-men alongside Mahkee 'Chava.

Personality
Rtas 'Vadum is a very solemn, and dutiful individual who will carry out his assigned tasks to the letter without hesitation. In the Five Leaders Summit, he voiced distaste in teaming up with the Alliance to Restore the Republic, believing that they were using the Sangheili as mere tools for the safety of their own interests. It was not until Arbiter Thel 'Vadam's explained everything to him, telling them that they would be working alongside each other as equals, that this concern abated.

Appearance
Unlike most Sangheili, 'Vadum has green eyes instead of orange. He stands an imposing 7 feet 11 inches tall and weighs 323 pounds. Perhaps the most memorable feature of his appearance is that he is missing his two left mandibles, as they were cut off in a fight. As such, he is commonly referred to as the "Half-Jaw". 'Vadum wears white armor during the final years of the Galactic Civil War. During his service with the Swords of Sanghelios and the Alliance to Restore the Republic, he donned standard combat armor that is used by Special Operations Commanders. Following the dawn of the Galactic Civil War, he began to wear the assault harness variant with noticeably larger shoulder pads, with a combat helmet.
