Otto-031

Black-Three (name and Spartan tag unknown) is a SPARTAN-II Commando of the UNSC Naval Special Warfare Command, assigned to Team Black as a heavy weapons specialist. His visor is etched with the Roman numeral "III".

Conscription
He was abducted and conscripted into the SPARTAN-II program by Dr. Catherine Halsey in 2517 when he was six years old. He was then taken to the planet Reach, and trained by the AI Déjà and Chief Petty Officer Mendez, along with the rest of the Spartan children.

Training
He was assigned to Team Black, and trained with the other teams such as the Red Team. During so, he had an unauthorized relationship with Black-One. They were ratted out by Victor-101 however, and put into the brig by Chief Mendez. Immediately following their release, a skirmish occurred, involving Black-One, Black-Three, and a few rowdy members of Red Team, which was set off by Black-Three's love affair with Black-One, which was debated as "non-Spartan behavior". In 2525, he and the other candidates underwent a series of augmentations to improve their abilities. Black-Three was among the ones that survived and were not crippled or killed by the procedure.

Later Career
Late in the Human-Covenant War in mid-2552, Black-Three served in the Battle of Verge and the Battle of Line Installation 1-4.

Personality and traits
Three's demeanor can be described as bold and particularly audacious, and he seems to genuinely enjoy fighting. He is generally outspoken and somewhat pragmatic, and his vocabulary usually consists of wisecrack-ridden military banter. Even so, he is shown to be rational and has demonstrated the ability to put personal feelings aside and stay focused on the task at hand, unlike Black-Four, who, despite his calm facade, is evidently prone to emotional breakdown mid-mission.
