The Neutralizer is an item that appears in Earthbound. It is a multi-use gadget that only Jeff can use, and can be found in the Monkey Cave by giving one of the monkey a fresh egg for it.


The Neutralizer affects all characters in battle, and undoes the effects of all PSI moves (including Mirror) used to that point in the battle, including any stats buffs and shields applied via PSI. Though it has no known appearance, it is described during the the fight with Boogey Tent as a "pale green light".
