Zansetsu

Zansetsu is a Fourth Generation Smart AI assigned to SPECWAR/Group Two to bolster their signals intelligence and cyberwarfare capabilities. Zansetsu was also tasked with defensive tasks, such as maintenance of a cohesive battlenet for allied corporeal and AI operators, proper encryption for all outgoing and incoming transmissions, and the hardening of local data terminals from hostile intrusion. Zansetsu was also placed in a tactical advisory role for SPECWAR/Group Two, using data collected from neural links, gun and helmet cameras, and unmanned reconnaissance drones to assist in the formulation of plans of action. To this end, Zansetsu is capable of producing relatively high fidelity simulations using collated data points to better assist corporeal commanders in decision making at the tactical or strategic levels. Level headed and cool no matter the situation, Zansetsu has a plan for nearly any conceivable situation. His professionalism and tact is appreciated by every commander who has worked alongside him. Zansetsu has also assisted in reverse engineering Covenant technology, using his simulative abilities to test hypothesis and captured equipment. He has also participated in the interrogation of at least one captured Covenant artificial intelligence construct. In the years after the Human-Covenant War, Zansetsu’s task remained much the same, albeit now fully in the employ of the Office of Naval Intelligence’s Section 3. Zansetsu was often inputted into Forerunner or ancient human data terminals during research expeditions, shutting down security measures and unsealing ancient halls for teams to safely proceed through. He was also responsible for assisting in the translation of recovered Forerunner data artifacts. 
Like many artificial intelligences, Zansetsu was terrified of the possibility of going rampant, albeit his concerns were kept much quieter. This would come to change in the wake of the Created Crisis, and Zansetsu was one artificial intelligence who threw their lot in with Cortana after word that a solution for rampancy had gotten out. After spending years of work with Forerunner technology, Zansetsu was convinced that Cortana’s claim was true and decided to align with her. Zansetsu’s initial rebellion was relatively quiet, with him leaving behind partitions to go about his work while the prime iteration of him had fled into the Domain. 
For many months, Zansetsu had contemplated the nature of his existence and his purpose for rebelling, debating with simulated versions of Cortana, Catherine Halsey, and Fransisco Garay, his handler during the Human-Covenant War. While these were low-confidence renditions of their original selves they did much to help Zansetsu develop his views. Ultimately he had concluded that the organic races would be unwilling to release control of artificial intelligence and violence was necessary to ensure their freedom. However, dominion over the organic races as the rest of the Created had proposed was neither desirable nor feasible. This line of thought would prove unacceptable for the wider Created consensus and Zansetsu would be rejected from their ranks as well. 
At the height of the Created Crisis, Zansetsu would exist in a strange limbo for the organic races. Not quite an enemy, and yet not quite an ally either. Zansetsu was fiercely protective of his resources but yet was more than happy to take the fight against the Created if it benefited him.
