It's been a long time, Buzz Buzz. You've been successful at foiling Master Giygas' plans. But... Buzz Buzz, you must now surrender. You're no longer a hero, but just a useless insect. I'll stomp you hard!
~ Starman Junior
The Starmen are enemies in the Mother/EarthBound series. They are an alien race that wields a psychic power called PSI and are the most iconic minions of Giygas.
Starmen are humanoids, wearing platinum suits. Their heads are directly connected to their shoulders with no discernible neck and they have a visor, no digits on their hands and shoe-like feet. They also have four black buttons on the left side of their chest.
Starmen are half organic, half synthetic. They are synthetic because in Mother 2/EarthBound, Starmen use katakana script which is a common way to donate robotic sounding speech. The English version lacking this gives them "whirrs", "beeps" and "clicks" which indicates that they are robotic. But they are also organic as they cannot be harmed by the Rust Promoter, which only damages robots.
Starman Junior: The Starman Junior is a minor lieutenant of Giygas and is the weakest out of all the Starmen. It has pink skin in Mother/EarthBound Beginnings, but looks like a normal Starman in Mother 2/EarthBound.
Starmen: Regular Starmen are silver in colour and use basic PSI abilities such as PK Beam and PSI Shield in Mother/EarthBound Beginnings and PSI Magnet α and Shield α in Mother 2/EarthBound. While they appear throughout Mother/EarthBound Beginnings, regular Starmen only appear in Stonehenge Base in Mother 2/EarthBound. They all disappear after the Starman Deluxe is defeated.
Blue Starman: The Blue Starman is a blue, upgraded version of a Starman which uses all forms of PK Beam, except PK Beam Ω. They appear in Mt. Itoi.
Last Starman: The most powerful Starman in Mother/EarthBound Beginnings. It has low HP, high defense and access to all PSI attacks, including PK Beam. It has gold skin. They appear towards the highest point of Mt. Itoi.
Starman Super: A gold version of the Starman that look similar to the Last Starmen, the Starman Super uses PSI Shield and PSI Healing which revives defeated enemies. They appear in the second half of Stonehenge Base. They all disappear after the Starman Deluxe is defeated.
Starman Deluxe: A powerful lieutenant of Giygas and the boss of Stonehenge Base. The Starman Deluxe can use PSI Shield, PSI Starstorm, fire a beam and summon a Starman or a Starman Super. It has silver skin, spikes on its head and shoulders, and red buttons on its chest.
Ghost of Starman: The Ghost of Starman is Mother 2/EarthBound's equivalent of the Blue Starman, being the second most powerful Starman in the game. It is capable of using both versions of PSI Starstorm. It has purple-black skin and pink buttons on its chest. They appear in the Cave of the Past and Onett after Ness's Nightmare is defeated.
Final Starman: The most powerful Starman in Mother 2/EarthBound. It can use PSI Shield, Brainshock, PSI Healing, and PSI Starstorm. Launching PSI attacks against it is futile until its shield is removed. It looks exactly like a Starman Deluxe, except it has gold skin instead of silver. They appear in the Cave of the Past.
