Offensive Bias (Earth-4001)

"The metarch looms over us, a servant greater than its masters, and, I hope, untainted. Soon we will know."

- The IsoDidact musing on Offensive Bias just before the Battle of the greater Ark

Offensive Bias is a metarch-level Forerunner artificial intelligence. One of the few Contender-class ancillas, it was created to counter the rampant A.I. Mendicant Bias. It commanded the last of the Forerunners' defenses at the greater Ark and at the final battle of the Forerunners. While seemingly less creative and independent than Mendicant Bias, Offensive Bias was still capable of coordinating inconceivable numbers of ships, sentinels, personnel, as well as an original Halo and the systems of the greater Ark simultaneously. More importantly, Offensive Bias was designed to be far more methodically lethal than Mendicant Bias.
