Jonathan Doherty

The Rookie (Serial number: 11282-31220-JD) is a Lance Corporal in the UNSC Marine Corps, joining on July 7th, 2547. Little is known of this marine other than his initials being "J.D." and that he was born in Crisium City, Naniwa, Luna.

He is an Orbital Drop Shock Trooper who was recently transferred from the 26th MEF, part of a Rapid Offensive Picket that suffered near-annihilation at New Jerusalem, Cygnus. Like most ODSTs, his actions speak louder than words. He served in Mombasa, Kenya in 2552 and is a part of Dare's squad.

Background
During the First Battle of Earth, The Rookie was one of the ODSTs with the mission to attack the Prophet of Regret's Assault Carrier positioned above the city of New Mombasa. However, in the last moment before the drop, ONI operative Dare took control of the squad. The Rookie himself, however, was largely unaware of this as he was sleeping. He was awakened by Romeo in a rather rude manner right before the drop.

As the squad dropped toward the ground, instead of landing onto the Covenant ship, Dare changed the squad's course towards the ONI Alpha Base on New Mombasa. Unfortunately, moments before they were meant to hit the ground, the Carrier jumped into Slipspace, generating a massive shockwave and an EMP, scattering the pods all around the city. The Rookie's pod in particular was slammed by Mickey's pod, cracking the pod's window and plunging it into free-fall.

Six hours later, The Rookie slowly woke up in his pod, in the occupied city center of New Mombasa. The city's urban infrastructure AI, the Superintendent, had been monitoring him and waiting for him to wake up. As the Rookie dropped to the streets below and started to move on, the Superintendent provided him with valuable help, such as activating signs and streetlights to guide him, as well as uploading a map of the city to his VISR database.

As the Rookie explored the city, he tried to piece together clues to find out what happened to his squadmates while avoiding the numerous Covenant patrols in the city.

Trivia

 * The Rookie is the main protagonist of Halo 3: ODST, a prequel and expansion pack to Halo 3.
 * The Rookie has been confirmed to have an action figure modeled after him by McFarlane Toys, the creators and manufacturers of the popular Halo action figures. It is set to be released alongside the other figures in the sixth series.
 * The Rookie's enlistment date is 07/07/2547. This is a reference to Bungie day, which is held on July 7th.
 * The Rookie is the first ODST you can play as in the Halo series without modding.
 * Theoretically he could not have been born after July 7, 2529, as he would have had to be at least 18 years of age to enlist. However both Romeo and Mickey appear to have been underage when they enlisted, so this may also be case with the Rookie.
 * The rest of his squad refer to him as "Rookie" because he is the newest member of the squad, despite the fact that he enlisted before and holds a higher rank than Mickey.
 * The Rookie's armor has gone through many cosmetic changes throughout the time period since the first announcement of Halo 3: ODST but seems to have reached a final look (shown above).
