certain key genetic markers as well as for his aggressively
competitive nature, John-117 was taken from his home at the age
of six and conscripted into the Spartan program. At fourteen,
along with 74 others conscripts, he underwent the Spartan II
augmentation process to enhance his speed, strength, skeletal
structure, intelligence, memory, reflexes and visual perception.
Only 33 Spartans emerged from the augmentation process intact.
John-117 quickly became the acknowledged leader of the Spartans,
rising to the rank of Master Chief Petty Officer in the UNSC
Naval Special Warfare Command.
Master Chief's Mjolnir Mark V Powered Assault Armor consists
primarily of a titanium alloy outer shell over a titanium
nanocomposite bodysuit. The Mark V's upgraded functions include
an integrated neural lace, enabling the suit to carry a
fully-functioning Artificial Intelligence to enhance the
abilities of its user. The Spartan's lifting capacity is
doubled, and reaction time is improved by a factor of five,
making thought and motion almost instantaneous. Additionally, a
self-recharging shield generator was installed
reverse-engineered from Covenant technology and the suit's
titanium helmet includes an integrated Heads Up Display.
Master Chief participated in nearly every major conflict by
human forces of the Covenant, including the Harvest Campaign,
the Battle of Jericho VII, the Raid on the Third Fleet Of
Glorious Consequence, and the Fall of Reach. It was while
retreating from Reach aboard the UNSC Cruiser Pillar of Autumn
that Master Chief was thrown headlong into the Battle of
Installation 04...known more commonly as Halo.
To his fellow Spartan II warriors, Master Chief is a leader. To
the soldiers of the UNSC, he is a demigod of war, an
inspirational titan on the field of battle. A hero to humankind
and a demon to The Covenant, he is humanitys best hope in the
face of total annihilation.
