Adriana-111

Adriana is a SPARTAN-II supersoldier. She was born around 2511 and was abducted by ONI to become a SPARTAN-II. She would constantly escape with SPARTAN Jai-006, but later would be captured by the trainers. It was for her that Spartan-006 decided to stay with the program. Upon returning to base after their final escape attempt, she met a Spartan named Mike. Together, these Spartans would come together to form Gray Team.

Like all of the members of Gray Team, Adriana shows less concern with protocol and the chain of command. She does not strictly adhere to Jai's orders, even though he is in charge of Grey Team. Almost a decade into the "Human-Covenant War", the Cole Protocol was put into effect. As such, Adriana and the other members of Gray Team are sent behind enemy lines in order to destroy the nav data held by the survivors of Madrigal, a world that had been glassed not long after Harvest.

Adriana is unlike most of the other Spartans-IIs. Where most of the other Spartans adhere strictly to protocol and the chain of command, she does not. She is not above openly questioning her commanding officer or even contemplating taking a UNSC Prowler without clearance. Also, she seems to not mind being out of her armor, whereas most other Spartans say that they feel exposed when they are not in their armor. She was partially responsible for neutralizing a situation that would have led to a massive violation of the Cole Protocol. Also, along with then-Lieutenant Jacob Keyes, she helped save over a million refugees of Madrigal, some of which were Insurrectionists. After the events at the "Rubble", she was assigned with the rest of Grey Team to a mission even farther behind enemy lines.

It has not been determined whether she survived to the end of the the War.
