Iratus is an artificial intelligence construct, based on a Jiralhanae donor and aligned with the Banished.

Biography
"That project was a walled garden. No one on the outside should have even known about it."

- LV106, regarding the Iratus project.

Iratus was created by the Lux Voluspa company as part of an effort to research artificial intelligence creation utilizing brain donors from species aside from humanity. This included Jiralhanae donors; a decision considered by researchers "LV038" and "LV106" as something that was "always going to draw some attention eventually." The Lux Voluspa facility was ultimately breached by a cyberwarfare attack, with an intrusion package deployed using internally-sourced encryption and displaying a Jiralhanae retrieval signature. The originators of this attack were later indicated to be the Banished, who were able to steal the Iratus AI matrix from the facility.

After Cortana's defeat at Zeta Halo, the Iratus AI was present inside the Banished shipbreaking facilities on Camber. When Spartan-IVs Sigrid Eklund and Hieu Dinh were deployed to the facility, they were able to trap Iratus inside of Dinh's neural interface, compromising his armor and cognitive functions. Eklund was ultimately able to commandeer a Banished Phantom back to the Avery J. Johnson Academy of Military Science to seek aid from friendly forces.

Upon arrival at the Academy, Spartan Laurette Agryna took the injured Dinh indoors where Iratus aggressively introduced himself. Agryna found schematics of the Banished facility on Camber through him and uploaded it to the Academy's combat simulation. In an attempt to irritate Iratus to leave Dinh's armor and go after another Spartan instead, she ordered her Spartans to hit the simulation in order to save Dinh's life. Iratus eventually left Dinh for another Spartan and was successfully contained along with a Banished archive.

Now a Personal AI contained by the UNSC, Iratus was casually used by Spartans in training simulations. On occasion, Iratus encouraged Spartans to join the Banished.

Halo Infinite
Iratus was added into Halo Infinite multiplayer as a personal AI in Season 02: Lone Wolves.
