Starro refers both to a starfish-shaped alien species also known as Star Conquerors, and their humanoid leader, Starro the Conqueror, a member of the Hatorei species who used their innate psychic abilities to gain control of a Star Conqueror Motherstar in the distant past and who uses the Starros as his instrument of conquest.

Science City was the site of one of the first attacks by the alien menace known as Starro the Conqueror. Starro sent one of his transformed agents to secure the Hall of Science building, and absorb the scientific knowledge of its residents. Wonder Woman and the Martian Manhunter of the Justice League of America flew to Science City to combat Starro and rescue the captured scientists.

In a possible future setting, a Starro took control of time traveler Rip Hunter and used him to send his spores backwards in time to Avignon, France in 1348. From there, he was able to retroactively take control of the entire world. The time-traveling super-hero Booster Gold used Rip Hunter's Time Sphere to travel to the future and correct the time anomaly that enabled Starro to come to power.[1]

Later, Starro takes control of L.E.G.I.O.N. and uses their widespread galactic influence to further his goals towards dominating the universe.[2]


  • Alien Physiology
    • Reproduction: Starro can asexually generate parasitic clones from his own body and command them to act in accordance with his will. By extension, Starro can also transform ordinary Earth-based starfish into loyal Starro agents.
    • Regeneration: despite its immense resilience and energy absorption capabilities, Starro probes are still susceptible to physical injury if dealt enough damaging force. The larger Starro's are capable of physiological regenesis in the likely event of suffering severe abrasion.
    • Flight: A fully grown Starro is capable of wingless flight in both outer space and atmospheric environments.
    • Mind Control: 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. 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.
      • Remote Mental Influence: Even without a Starro parasite directly controlling a host, The larger Starro can influence minds on a more indirect level by reaching out to the dreaming within the resting subconscious mind. Able to appropriate induced sleep within a host to ensnare them within it's own wakeless fantasy allowing it to probe and assimilate the minds of countless potential vessels that it can then seed with a smaller Starro organism later on.
    • Energy Absorption/Projection: Starro; both mini-clones and larger proginator, can absorb energy and rechannel it as powerful blasts of energy, which it directs through the tip of each tentacle as well from its central eye.
    • Invulnerability: A fully grown Starro is impervious to most conventional forms of attack. Gunfire and similar weapons are ineffective against a Starro.
    • Color Alteration: Starro can change the color of its skin to (presumably) any color of its choosing. It once changed its hue to yellow in order to fend off attacks by Green Lantern.
    • Terraforming: The much larger Starro' in the parasitic species roster can range to the size of planetary ocean bodies in scale. As an added quality these massive probes are capable of aggressively changing global ecosystems on a small or larger scale such as alienating the whether patterns for offensive needs.

  • Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
  • Starro the Conqueror was created by writer Gardner Fox and artist Mike Sekowsky. The Starro species was further developed by writer Grant Morrison.
  • The biology of the Starro parasites is similar to, and predates, that of the Facehugger parasites seen in the 1979 movie, Alien and its corresponding sequels.
