Roma-143

Black-Two (name and Spartan tag unknown) is a SPARTAN-II Commando of the UNSC Naval Special Warfare Command who served with Team Black as an intelligence specialist. Her visor is etched with the Roman numeral "II".

Conscription
She was abducted and conscripted into the SPARTAN-II program by Dr. Catherine Halsey in 2517 when she was six years old. She 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. She was assigned to Team Black, and trained with the other teams such as the Red Team. In 2525, she and the other candidates underwent a series of augmentations to improve their abilities. Black-Two was among the ones that survived and were not crippled or killed by the procedure.

Mission to Verge
Late in the Human-Covenant War, Team Black was sent to the former UNSC colony of Verge, now in the process of being strip-mined by the Covenant for helium-3.

Line Installation 1-4
In late 2552, Team Black was to embark on a covert mission to infiltrate a Covenant vessel. When their ship crash-landed on an Unnamed Moon, Black-Two stayed behind to drop a Slipbeacon to Fleet Command while the rest of the team went to scout the area. After Two was finished, she moved out into the Line Installation. While she was inside the structure looking for her teammates, 686 Ebullient Prism took control the HUDs of the team's MJOLNIR armors to deceive them and to pit them against each other. After Prism led Two to a Beam Rifle, Two found her way to a ledge where she spotted Black-Three, who appeared on her helmet display as a Hunter. Two opened fire on him, oblivious of the fact her HUD was being manipulated. In turn, Black-Four saw Black-Two as Thon 'Talamee and shot her in the head, injuring her. Knocked unconscious, Black-Two awoke some time later as the wound was healed by Biofoam. After waking up, she made her way into the Installation's command center, where she helped the rest of the team destroy 686 Ebullient Prism. After being severely damaged, the monitor was destroyed as it flew into the Installation's main weapon just as it fired at an incoming Covenant fleet. The fleet crashed on the moon, and Team Black moved back to the surface in order to find a serviceable vessel they could commandeer to escape. Outside, they faced a massive Covenant ground force.
