Solomon-069 was abducted and conscripted into the SPARTAN-II program by Dr. Catherine Halsey in 2517 when he was only six years old. Solomon was then taken to the human colony world of Reach, and trained by the AI Déjà and Chief Petty Officer Mendez, along with the rest of the Spartan children. He was known to be aggressive and headstrong.

In 2544, Solomon participated in an operation to retrieve the captured Catherine Halsey from the Covenant's Third Fleet of Glorious Consequence, along with a team consisting of Arthur-079, Kelly-087, Fred-104 and led by John-117. Operating an EVA Booster Frame in an attempt to infiltrate a Covenant ship, Solomon detected a signal from one of many CCS-class battlecruisers in the fleet, managing to enter through the curiously unshielded hangar and reached what he assumed to be their target. However, it turned out to be a false signal, and he discovered a Covenant antimatter charge, which subsequently detonated. The explosion destroyed the ship and vaporized Solomon with it.
