Victor was born around 2511 and was one of a genetic make-up that the Office of Naval Intelligence and Dr. Halsey were interested in. After being selected as a suitable candidate for the SPARTAN-II Program in 2517, he was abducted and sent to Reach, and trained by the AI Déjà and Chief Petty Officer Mendez, along with the rest of the Spartan children. He was assigned to Team Black, and trained with the other teams such as the Red Team. In 2525, he and the other candidates underwent a series of augmentations to improve their abilities. Black-Four was among the ones who survived and were not crippled by the procedure.
While being trained by SCPO Franklin Mendez, Black-One and Three secretly had a romantic relationship. Victor was jealous of them and reported them to Mendez, who sent both to the brig. Red Team then heard of this and tracked down Black-One. In the ensuing struggle, Black-One lost her left eye to send the message that her team should take their training seriously. Soon, Black Team gave Red Team a beating in return and were given a ten-day stint in the brig as a result. Victor never spoke with Black-One after that incident. Later, Victor developed a false memory that it was he who had had the relationship with Black-One.
Battle of Verge
In mid-2552, during the Human-Covenant War, Team Black was sent to destroy a heavily-fortified Covenant Beacon within the ruins of Cuidad de Arias on the UNSC Colony world, Verge. Black-Two encountered an apparently non-hostile Yanme'e, and convinced the other members that they could trust the Drone for intelligence on the area. Hopalong, as the Drone was nicknamed, led Team Black accordingly through underground tunnels that were hollowed-out by swarms of Drones. Black-Two, during their attack on the Mgalekgolo and Kig-yar positioned by each pylon, discovered that the Drones were psychopathic prisoners rather then slaves as Hopalong led them to believe. Team Black was able to set C-12 Shaped Charges just before Hopalong freed the hostile Drone inmates. Although Black-Three struggled with the swarm and was ultimately rescued by Black-Two, the team escaped the area and the charges on the pylons were detonated.
Some time after the mission on Verge, Victor partook in the Battle of Line Installation 1-4 on an uncharted moon. He carried the AI Iona within his MJOLNIR suit. When Black-One was captured by mechanical Gatherers, Victor and Black-Three reluctantly allied with the Covenant forces also on the moon in order to rescue their captured comrades. However, the Forerunner Monitor of the Installation, 686 Ebullient Prism, hacked into Victor's MJOLNIR HUD, tricking him into attacking his allies, wounding Black-Two and nearly killing Black-Three. Viewing everyone as Black-Three, Victor was determined to settle his grudge against Three. It took Three and Iona to remind him of the importance of his adopted family, snapping him out of his frenzy. Team Black then went to assist One against Prism. They destroyed the Monitor with the Installation's main gun, simultaneously bringing an entire Covenant fleet crashing down. Team Black then went out to fight the survivors so as to commandeer a functional Slipspace drive to get off the unnamed moon.
Personality and traits
Victor is generally quiet and reserved. He is also exceptionally calm; no matter the situation, Black-One noted that Victor's voice never as much as wavered, something she found extremely disturbing. This makes him appear near-emotionless to the outside, and particularly hard to read. Despite this however, he appears to only contain his emotions, as he suffered an emotional outburst during the battle at the Line Installation, relating to an incident in the team's training days. This, coupled with the fact he developed a false memory he genuinely believed in about the relationship incident would suggest he is somewhat emotionally unstable.
