Aberration

Aberrations were creatures from or touched by the Far Realm, thereby making them utterly alien to the Prime Material Plane, the fundamental planes, the parallel planes, or any other regions of the local cosmology. Aberrations generally all had bizarre anatomies, strange abilities, alien mindsets, or any combination thereof. Most aberrations had darkvision out to 60 feet. As a group, they had no other special abilities or immunities.
