The Counter-PSI unit is an item in EarthBound, only usable by Jeff. It is gotten by fixing the Broken machine, gotten from Apple Kid in Twoson, with at least an IQ value of 1.

Its purpose in battle is to render an opponent unable to use PSI for three turns, much like PSI Block, except that one lasts until the end of the current battle. Its success rate doesn't seem to be high however, and is particularly useless on stronger enemies.
