Telekinesis

Telekinesis is a psi-power commonly used by most psychics, enabling them to lift and manipulate objects and living beings with their minds. It is abbreviated as "TK."

Manifestation
Telekinesis manifests in a number of different ways.

The use of telekinesis is sometimes completely invisible, with the object being lifted with no other visible evidence of psychic powers being used. Sasha Nein in particular is shown to use this invisible version of telekinesis, shown by how he sometimes levitates the cigarettes he smokes, and also how he levitates Loboto.

Other times, telekinesis manifests as a semi-transparent psychic hand holding the item, animal, or person. The hand does not necessarily have to resemble the user's hand. The color of the hand is often the color of the user's psychic energy. This is seen in Razputin Aquato, who uses an orange TK hand that resembles his own physical hand.

Uses
Telekinesis is used to lift objects and living beings (both mental and physical) with the mind. This use is limited, however, as some characters note that even when lifted with telekinesis, an object can feel "heavy," and some things can only be lifted a short distance off the ground and cannot be carried.

Psychics can also use telekinesis to throw items, which can be used to attack enemies.

Behind the Scenes
NOTE: The information in the following section is non-canon.

Due to a glitch in Psychonauts 2, telekinesis can be used in conjunction with psi-blast to create a technique that has been dubbed "prop-surfing," which enables players to grab an item with telekinesis, stand on top of it, and charge a psi-blast.
