Isaac-039

Summary
Isaac-039 was one of the SPARTAN-II supersoldiers. Isaac was not well known among the Spartans, likely because he did not seem to have a close relationship with John-117 or Fredric-104. He did, however, appear to be close to Vinh-030.

Biography
Isaac was conscripted into the SPARTAN-II program in 2517 at age six, when Dr. Catherine Halsey singled him out as a physically and intellectually superior child. He was abducted from his home and replaced with a Flash-Clone. He was then taken to Reach where he was trained with the rest of the Spartan soldiers by Deja and Chief Petty Officer Mendez.

Isaac was never mentioned by name until the Battle of Reach in 2552. He was assigned to Red team, under charge of Fred. They were assigned to the surface of Reach to defend the generators for the orbital MAC guns. As they descended, their Pelican, Bravo 001, was hit and the Spartans were forced to jump from the crashing vessel. Isaac was wounded during this jump, suffering two dislocated arms which hampered his fighting ability severely.

He was then assigned to "Delta" Team by Fred, under charge of Will-043. Their mission was to secure the fallback position for the Spartans- CASTLE Base. Vinh, Will, and Isaac were separated from three other Spartans and the remaining members of Charlie Company but arrived at CASTLE Base. They were unable to enter the facility until Fred and Kelly-087 met up with them and whispered Oly Oly Oxen Free into the speaker of the facility. Dr. Catherine Halsey was present, and opened the door for them. He was then checked out by Dr. Halsey and sent to survey perimeter defenses for the facility, along with Vinh. This proved unnecessary however, as the Covenant attacked immediately.

Vinh, Isaac, Fred, Kelly, Will, and Dr. Halsey were then trapped under CASTLE Base for several days after Halsey activated Operation: WHITE GLOVE to destroy the base and keep it from falling into enemy hands. Isaac was able to upgrade his MJOLNIR armor with parts salvaged from the base.

After Fred discovered the massive room containing the Forerunner Crystal, it sent a massive radiation spike that allowed the Covenant to triangulate on the group's position. A Covenant Gravity Lift quickly appeared. The group retreated to a nearby tunnel, as Vinh and Isaac dropped Satchel Charges to cover the Spartan's tracks. The Charges detonated, but Vinh and Isaac disappeared. They could not be raised on the COM and it is highly likely that they are dead. Isaac is listed as MIA, but is assumed to be KIA. It is possible, though extremely unlikely, that he was captured by the Covenant and is still alive.
