Frightbots are a type of evil robot found in Mother 3, utilized mainly by the Pigmask Army to act as instruments of torture with their ability to tell frightening stories.

They are found in Saturn Valley, where several terrorize the Mr. Saturns alongside Pigmask Captains and Majors, who keep the Mr. Saturns captive in their own houses.

Frightbots have the appearance of small grey projectors with speakers, are oddly known for telling various weird-sounding stories to Lucas and his party. They have relatively low HP, offense and defense, and are vulnerable to explosives and PK Thunder. Their battle music is "Zombeat".
