Psion

Psions are a powerful race of clairvoyant, psionic beings who were conquered and enslaved by the Cabal in the hopes of weaponizing their abilities. At some point, they created the OXA Machine, a machine able to perceive the future, but the Cabal destroyed it. Freeborn Otzot, a particularly brilliant Psion, later succeeded in rebuilding the OXA Machine, but ironically is the reason why their enslavement has been prolonged.

Destiny
The strength of a Psion's attack depends on the type of Psion. An ordinary Psion will only be able to attack at point blank range, a Psion Operant will be able to launch a short-range attack, and a Psion Flayer will be able to send a psychic attack from quite a long distance. These attacks deal Arc (or electrical) damage, signifying their power over mind and (potentially) machine. Certain Psions are known to channel Void and Solar power, though this is restricted to Flayers observed in the Prison of Elders. Psions become much more dangerous during Nightfall Strikes, as they acquire a Void shield.

Destiny 2
A sect of Psions belonging to the Red Legion utilize new Void-based abilities as well as Cabal Headhunters. These Psions have an upgraded version of their old wave attack, now referred to as a "rupture ability," which explodes and launches enemies into the air. When killed through a headshot, the upper parts of their heads are visible, revealing that they have bald, veined heads, with a single eye, reflected in their helmets. These eyes can be either blue or orange.
