The Contender

"The Contender" was a fragment of abstracted personality. It was ultimately destroyed by Flood-infected battleship that had destroyed the Forerunner vessel that was ferrying it to the Ark.

Nothing is currently known about "The Contender", other than it's translated title. Mendicant Bias was a Contender-class Ancilla, therefore, it can be assumed that "The Contender" was simply a fragment containing basic protocol for a Contender-class AI, however likely corrupted it was at the time of it's destruction.

History
In order to prevent Mendicant Bias from subverting or harming him, Offensive Bias had shattered of Mendicant Bias into its component sections and scattered them throughout the few remaining ships of his fleet for transport to Installation 00, where he would study the fallen AI construct. Much of his fleet was destroyed or ravaged by the Flood, as per the case with "The Contender".
