PSI was originally used by [[Giygas]]'s race. When [[George]] and [[Maria]] were abducted by these aliens in 1909, George studied the powers and eventually learned to use them and eventually passed them down to [[Ninten]], his great-grandson. Much later, it was shown that in the year 199X, [[Ness]], [[Paula]], and [[Poo]] could each use different types of PSI.

Each PSI move can have up to 5 ranks: α, β, γ, Σ, and Ω (Also π and Supr in Mother).
PSI moves become stronger as the user levels up, its power level being designated by the Greek letters α (alpha), β (beta), γ (gamma), and Ω (omega), as well as Σ (sigma) and π (pi) in some cases.
 
They moves are also separated into four different categories:
There are also four categories of PSI: Assist, Offense, Recover, and Other. Most offensive PSI can be countered by high ranks of [[PSI Shield]] or [[PSI Counter]].
*'''Assist PSI''': for PSI moves that alter parameters of allies or foes, inflict status effects, or shields.
*'''Offense PSI''': for PSI moves that inflict damage. All PSI moves in this category are called ''PK'', except on [[Earthbound]].
*'''Recover PSI''': for PSI moves that replenish HP, PP, or remove status effects.
*'''Other PSI''': for PSI moves designed to be used on the overworld map, such as [[Teleport]]. This category does not exist on [[Mother 3]].

PSI costs PP to use, which can be recovered by eating certain foods or resting at a hotel. When a character [[Status ailment#Can't concentrate|can't concentrate]] or is [[Status ailment|forgetful]], they can't use PSI. In [[Mother 3]], when a character is learning a new PSI technique, they will become [[Status ailment|feverish]], slowing them to a walk.
