Starman

The Starman  is a main enemy from the EarthBound series who appears as an Assist Trophy in Super Smash Flash 2.

Character description
Starmen are extraterrestrial beings, and are among the original users of PSI. They are common among the higher ranks of Giygas' army.

It is unknown if Starmen are organic or synthetic, or if their outward appearance is just a suit; the American EarthBound player's guide implies in their enemy descriptions that Starmen are robots. Their speech in EarthBound also reflects this; in Mother 2, Starmen use the katakana script, which is a common way to denote robotic-sounding speech. The English version, lacking this, gives them "whirrs", "beeps" and "clicks", to indicate they are robotic beings. However, they may be organic, as the Rust Promoter, which is supposed to damage mechanical enemies, is useless against Starmen of any kind. Same goes for PK Beam γ in EarthBound Beginnings, as it does not affect mechanical enemies, yet can damage any Starman, save for the Starman Junior. Also, an enemy called "Ghost of Starman" is encountered towards the end of EarthBound, but if the Starmen are robots, they would not be able to become a ghost. The description of the Ghost of Starman in the EarthBound player's guide refers to it as an alien. They may also be connected via a sort of "hivemind"; when the Starman Deluxe is defeated, any Starmen summoned during the battle are defeated as well, and the Stonehenge Base becomes devoid of enemies.

Starmens' arms and legs do not seem to move, so Starmen instead appear to move around by means of teleportation (though this type is different from PSI Teleport). This can be seen when Ness approaches a Starman in EarthBound, as they will then teleport directly behind him and occasionally trigger a surprise attack in their favor.

In Super Smash Flash 2
Much like they do as Assist Trophies and enemies in Super Smash Bros. for Nintendo 3DS and Wii U, when a Starman is summoned in SSF2 it teleports around and attacks with two possible variants of PK Beam: PK Beam γ, which is a single focused beam attack, and PK Beam Ω, which is a barrage of beams in all directions. The beams can be reflected and absorbed.
