Psionics

Psionics are individuals with psychic powers and abilities. This includes ADVENT, GUTHALOT, and Human forces.

Psionics are rated on a 1 to 5 scale. A psionic rating of 1 means the individual has no psychic ability. A raiting of 5 means the individual has extremely powerful psionic ability.

All standard Human, Alien and ADVENT/GUTHALOT are Class 1 Psionics, meaning they have no active ability but are still vulnerable to Psionic effects.

A Sectoid is a Class 2 Psionic.

A standard Psi Operative is a class 3 Psionic.

An ADVENT/GUTHALOT priest is a Class 3 Psionic.

A Gatekeeper is a Class 4 Psionic.

An Avatar is a Class 5 Psionic.

All Chosen are Class 5 psionics.

Brice Price is the only individual who is off the scale, coming in as a Class 6 Psionic. This means she is twice as powerful as any class 5. There is a common theory that Turbo might also be a Class 6 Psionic, due to his ability to survive without a body.
