A Contender-class Artificial intelligence was a Forerunner A.I class that was the most advanced of its time.[1]

During the Forerunner-Flood war, one or more Contender-class A.I was created, 032 Mendicant Bias, and possibly the monitors of the Halo Arrays designed with the sole purpose of drawing out the parasite’s central intellect, the Gravemind and then begin gathering information from it. When instructed by the Forerunners, the AI would then unrelentingly attack the Gravemind until the beast withdrew from their galaxy or perished.[2] Only five Contender class A.I were ever made.

Known Contender-class AIEdit


  • It is possible that Offensive Bias was a Contender-class AI, as he was able to communicate with Mendicant Bias.
