Sentient starfish-shaped alien species with a central eye and prehensile extremities. They are also known as Star Conquerors. Adult Starro can asexually generate parasitic clones from their own body and command them to act in accordance with his will. Although equipped with only limited mobility, Starro parasites can attach themselves to a victim's face, whereupon they attack a body's central nervous system, subsequently taking control of both their mind and body, acting as transmitters of the adult starro's will. A Starro parasite can maintain control over its victim for an extended period of time, forcing them to obey their every whim, even if it goes against the nature of the selected target. This ability only works so long as the parasite maintains physical contact with its victim. Once the parasite is removed, the victim regains control of their mind and motor function.
Starro can absorb energy and rechannel it as powerful blasts of energy, which it directs through the tip of each tentacle and generate energy fielsd allowing them flight in both outer space and atmospheric environments.A fully grown Starro is impervious to most conventional forms of attack. Gunfire and similar weapons are ineffective against a Starro. Starro can also change the color of its skin for different purposes,
The first passage of a Starro on Earth happened in 1960. It was destroyed shortly after its arrival but surviving fragments managed to redevelop sentiance afterward from time to time.
