PSI

PSI (Psionics), including the subcategory PK (Psychokinesis), are the psychic powers that appear throughout Mother series.

Origin and discovery

PSI was originally the provenance of Giygas's race. When George and Maria were abducted by these aliens in the early 1900s, George studied the powers and eventually passed down his research notes to Ninten, his great-grandson. Many humans with no connection to the aliens or to George's family line are also shown to be able to use PSI, such as Ana, Ness, Paula, Poo, Lucas, Claus, Kumatora and the Garrickson baby.

Types of PSI

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:

• 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.

Qualities of PSI

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

Memo description

"PSI is a mysterious and useful power that can replenish your energy or even assist in your transportation needs. Using PSI will deplete your PP."
