SPARTAN-X879

Born in 2527 to a pair of rebel parents onboard an asteroid lair, Daniel was brought up to hate the UNSC. After his parents died attacking a UNSC Fissile Munitions factory, Daniel was lost. He was quickly taken by ONI operatives and conscripted into the SPARTAN-X Program. However, he never really truly came over fully to the UNSC. Inside that, he was given command of Fireteam Cobra, and became close friends with SPARTAN-X117 Charolette Riggers. 
He soon became Jake Hammer's rival, and his team competed fiercly with the others. In 2552, he took part in Operations Shadow and Anvil, and nearly died during the insertion into New Paris' atmosphere. He fought his way through the planet, but was captured by Covenant forces planting a bomb. He was lead around for over a month before they dropped him in the Prison Hold of the Fist of Justice, where he took part in the Second Battle of Installation-04. 
His current status is unknwon.
