Master Chief Petty Officer John-117 , more commonly known as the Master Chief , is a SPARTAN-II commando of the UNSC Naval Special Warfare Command. He is the protagonist and main character in both the Halo trilogy and Reclaimer Saga . With over thirty years of active duty, he has become one of the most decorated war veterans in the United Nations Space Command , earning every known UNSC medal except the Prisoner of War Medallion.
John was born in 2511 and lived with his mother and father in Elysium city on the colony world of Eridanus II. He attended the Elysium City Primary Education Facility Number 119. As a child, John had brown hair, freckles, and a small gap between his front teeth. In a dream during cryo -sleep aboard the UNSC Pillar of Autumn , John recalled that his mother "kind of smelled like soap," and that she had "large eyes, a straight nose and full lips." 
The would-be UNSC Marine Lieutenant Parisa was a childhood friend of John's who John once saved from drowning at Lake Gusev ; John thereafter promised to marry and protect her. Parisa's father shot a photo of the two soon after that Parisa kept as a memento long after she thought John had died.  John was also friends with Ellie Bloom and Katrina during his childhood. Some nights, John would lay in grass fields with the girls and the three of them would look up at the stars together.
