Three of Five (William McRaven)

William’s family began as scientists sent to Deneva as a part of a team to help the planet research for the United Federation of Planets. The Borg attacked his planet. As a result of the invasion, he was assimiliated. Later, on a mission for the borg, the captured vessel that he was on with his fellow drones crashed on a planet, and they became stranded. After several years, they lost their connection to the Hive, and started getting their consciousness back. Being freed from the collective, he found his way to Earth, where he joined Starfleet. He wanted to redeem himself from the things he did as a borg. He was mostly adequate with his training, he excelled in engineering, repairing ship components. He hasn’t consciously used his cybernetics since he has been freed from the collective.
