Ghost (Marine)

"I need you to be strong - strong enough to do what you've never done in your life. Can you be strong enough to allow yourself to be... can you just be human?"

- A dying Marine under Ghost's command

Sergeant "Ghost" was in the Hades Corps of the UNSC Corps of Engineers. He was know for being cold, showing little to no emotion toward his Marines.

Biography
His is a very inspiring story. He was known among local Marines after an engagement with Covenant forces that left his entire platoon decimated. During that incident, a dying Marine asked Ghost to be human for once, as he came across as a cold-hearted, soulless individual. The Marine died in his arms, and Ghost "died inside", crying out into the sky and vowing to avenge his fallen platoon.

Battle of Algolis
"And for one last instance, I'm human again."

- Ghost's last words

Ghost was deployed with the Hades Corps to destroy navigation material and prototype weapons during the Battle of Algolis, as per the Cole Protocol. At first it appeared that he disobeyed orders to destroy a set of Prototype Armor by joining the battle in it, however he insisted that he is performing his duties by using the time left until self-destruct initiation to provide cover for the soldiers and civilians' extraction. The initiation of the self-destruct's final phase requires a voice command.

Ghost held off Covenant forces long enough for a group of evacuation shuttles to escape. He was overwhelmed shortly after. Seeing that the evacuation shuttles escaped safely, Ghost commented on his newfound humanity before uttering the code to activate a nuclear self-destruct feature on his armor -- the code was "be human". The resulting blast annihilated the surrounding the Covenant infantry.

A Marine commander in orbit of Algolis edited a log of the events, redacting requests for Ghost to be court-martialed, marking him Missing In Action, and stating that he demonstrated great conduct as a Marine and a human being.
