Spartan Davis is a playable character in the game Halo: Spartan Assault. Very little is known about him. He was one of the first recruits to be added into the Spartan-IV Program and participated in the Battle of Draetheus V.
Davis was deployed to Draetheus V along with Sarah Palmer when a group of Covenant Remnant attacked. He was sent to Dreatheus V's moon X50, which was revealed to be a superweapon capable to destroy planets made by the Forerunners. He stopped the Covenant forces before they could use the weapon to destroy Dreatheus V. He later died protecting evacuating UNSC forces.
