Unmutuals

Unmutuals are Yanme'e who suffer from the equivalent of a personality disorder, where the affected creatures are unable to function as a single coherent low grade hive-mind, leading to significant problems in such a rigid socialised species, creating the equivalent of psychopaths - they brutally attack other Yanme'e sometimes with little provocation, and smash eggs. These individuals are outcasts, sentenced to work as slaves in Kig-Yar operated penal work colonies, where they are worked to death.

One such penal colony was transferred to Verge, where they worked to maintain the local Beacon. They were accidentally freed by Team Black, tricked by a lone individual who offered an alliance between the Yanme'e and the UNSC. While many of these Yanme'e were killed by the destruction of the Beacon, there may have been survivors.
