Unmutuals

Unmutuals are yanme'e who suffer from a (or perhaps multiple) Yanme'e personality disorder(s), where the affected creatures are unable to function as a single coherent low grade hive-mind, leading to significant problems in such a rigid socialized species. This inability to function turns them into 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 and often tortured. However, despite their violent, random natures, some Unmutuals can be clever and intelligent.

One such penal colony was transferred to Verge, where they worked to maintain the local beacon with a constant supply of helium-3. 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 by Black-Two, there may have been survivors.

The term "unmutuals" is an inexact translation from the original Covenant word. Another descriptive term is "incapable of socialization."
