John-117

Master Chief Petty Officer John-117, also known simply by his rank as the "Master Chief", is a Spartan-II supersoldier of the UNSC Navy's Special Weapons division. He served as one of the most important figures of the Great War alongside the "Smart" A.I Cortana.

=== Early life ===
Born on March 7, 2511, John 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. The would-be UNSC Marine Lieutenant Parisa Andrews was a childhood friend of John's. John once saved her from drowning at Lake Gusev, after which he promised to marry her and keep her safe. A photo of the two was also taken by Parisa's father soon after, and would be kept as a memory by Parisa long after she thought John had passed away. He also was a friend of Ellie Bloom, living next to each other in their childhood, and Katrina, who played obstacle races with him and Ellie.
=== Spartan training ===
John and the rest of the children chosen for the SPARTAN-II program were brought to the Reach FLEETCOM Military Complex, their new home for the next several years. There, Lieutenant Halsey informed the children of their new purpose: they were destined to become protectors of Earth and all its colonies. The next morning John discovered his service tag, stitched into his training uniform, and his new name: John-117. John began adjusting to his new life, training with other Spartans under Chief Petty Officer Franklin Mendez.
In their first training exercise, John was grouped with fellow trainees Kelly-087 and Samuel-034 in a game of "Ring the Bell". John rushed ahead of his teammates and crossed the finish line first; however, he was befuddled to learn that his team had lost, as Kelly and Sam came last. This taught John the importance of teamwork and the next day, his team scored higher. John soon bonded with Kelly and Sam, who would become his first and closest friends among the trainees. For eight years John was schooled in history, military strategy and tactics, and weapons, and was given extreme physical training. During his training, John used to tease Serin-019 and her habit of eating leftovers from meals of the other candidates.
John quickly proved himself to be one of the program's top candidates. Both Dr. Halsey and Chief Mendez identified him as one of four emerging leaders within the Spartan-II group, along with Kurt-051, Jerome-092, and Frederic-104. Halsey believed John held both the skills and natural ability to lead the entire Spartan-II group. Mendez disagreed with her assessment, instead believing Kurt would fulfill the role as team leader. John's leadership skills were correctly observed, as the results from their mission clearly solidified his role as the overall leader of the Spartan-IIs. He also became the established leader of Spartan Blue Team.
== Physical appearance ==
As a child, John had brown hair, freckles, and a small gap between his front teeth.
