- "A man from the stars."
- — Description in Mother.
Starmen appear in many places in Mother, and know PK Beam and PSI Shield. One can first be fought as a boss, appearing as a monochromatic hotel worker in Halloween's hotel that attacks Ninten and co. after they sleep the night. As an enemy, they can be found in Valentine, the Advent Desert, north of Easter, the Swamp, and at the base of Holy Loly Mountain.
Starmen reappear in EarthBound, where they are found in the Stonehenge Base. Here, they are significantly stronger; they can fire a beam, guard, use PSI Magnet α, Shield α, or use a Sudden Guts Pill. Solidifying them with items such as Jeff's Slime Generator or the Monkey's Love has a relatively high chance of success. They provide a substantial amount of experience when defeated.
