James Ackerson is an intelligence operative who has spent his career climbing the ranks of the UNSC’s secretive Office of Naval Intelligence.


Early Life[]

James was born to a bridge builder on Reach. He, his mother, and sister Julia lived together happily. They often spent time with James's paternal uncle Arthur. Julia was stolen by Dr. Halsey at the age of six and placed into the Spartan program. She didn't survive the augmentation and died. At some point, James's mother died and his father developed a form of dementia.[1]


Before his promotion to ONI, James was a soldier who saw combat.[2]

SPARTAN-II Program[]


James Ackerson introduces himself to Master Chief and the Silver Team, explaining that he is Dr. Halsey's replacement and the new leader in charge of the Spartan program. He expresses his intention to utilize the Spartans to their full potential and highlights his reluctance to dismantle anything built by Halsey.

Ackerson and John don't see eye to eye. He presses Master Chief about unauthorized projects run under Dr. Halsey. He questions the credibility of John's account of the events on Sanctuary, stating that there is no confirmation from other soldiers. Ackerson even interrogates Kai, pressing her for information about John's wellbeing.

Later, it is revealed also that Ackerson is the person responsible for keeping Dr. Halsey captive. He engages with the Halo Keystone, and consults with Cortana, learning that there is a 97% probability of something happening.[2]


Ackerson is a confident and self-assured man.
