The character debuted in The Brave and the Bold #28 (March 1960) in the story "Starro the Conqueror", which was also the first appearance of the Justice League of America.[2] According to editor Julius Schwartz, the title "Starro the Conqueror" was inspired by a Ray Cummings story, "Tarrano the Conqueror".[3][4] The second appearance of Starro was 17 years later in an 11-page Aquaman story in Adventure Comics #451 (May–June 1977). It appeared again only four years later in a two-part story in Justice League of America #189–190 (April–May 1981), then again a year after that in an alternate universe story in Captain Carrot and His Amazing Zoo Crew! #1 (March 1982), and it appeared briefly in Crisis on Infinite Earths #9 (December 1985).
In post–Crisis on Infinite Earths DC comics, Starro appeared in a five-part story in Justice League Europe #25–28 (March–July 1991) and was revamped and reintroduced in JLA Secret Files #1 (September 1997) and JLA #22–23 (September–October 1998). Another version of the character featured in the intercompany crossoverJLA/Avengers #1–4 (September 2003 – May 2004); Teen Titans (vol. 3) #51–54 (November 2007 – February 2008); Green Lantern/Sinestro Corps: Secret Files #1 (February 2008) and Booster Gold (vol. 2) #13–14 (December 2008 – January 2009).
Its post–Infinite Crisis appearances include R.E.B.E.L.S. (vol. 2) #1–13 (April 2009 – April 2010) and R.E.B.E.L.S (vol. 2) Annual #1 (December 2009). Another version appears in Forever Evil #1 (November 2013), and a new version called Genetically Modified Starro appeared in New Super-Man #4 (2016).
Starro is a highly advanced starfish-like alien with a single central eye and prehensile extremities. The entity visits Earth and empowers three starfish; the creatures begin wreaking havoc, such as exploding an atomic bomb and absorbing its energy, kidnapping scientists and absorbing their brain power and placing the residents of Happy Harbor, Rhode Island, under mental control. Eventually, they are stopped by the superheroes Aquaman, the Flash, Green Lantern, Martian Manhunter and Wonder Woman. The heroes defeat Starro by coating it with quicklime, which nullifies its abilities.[5][6] A segment of Starro survives and regenerates into a complete creature, but is stopped by Aquaman before being able to renew its plan of conquest.[7]
Starro eventually reappears and forces humans to nurture it until it is able to assume its former proportions. Being able to reproduce asexually, Starro creates millions of miniature duplicates of itself, which the authors called spores. These spores attach to the faces of the entire population of New York, allowing Starro to control their minds with its own. The creature uses these spores to control several members of the Justice League until it is defeated by extreme cold.[8] Later, after Superman is accidentally transported to an alternate universe, Starro is again defeated by Superman alongside Captain Carrot and his Amazing Zoo Crew. Superman then takes the defeated Starro back to his universe.[9]
Starro later convinces Justice League Europe that it is dying and wishes to return to space. Aided by former Green Lantern Kilowog, Starro returns to his original spaceship and tricks the heroes by programming it to explode. It then releases thousands of spores over a fictional version of Western Europe. Controlling the minds and bodies of thousands of humans, Starro seizes power, with several members of Justice League Europe opposing the alien. Starro is finally defeated when the Justice League member Ice freezes the original Starro.[10]
During JLA and referring to itself only as It, another member of Starro's species takes control of the Flash and the population of the fictional Blue Valley using spores. Although the JLA intend to intervene, they are advised against doing so by the Spectre, who reveals the alien's intention is to capture and control the heroes and use their special abilities to conquer the galaxy. The JLA requests the Spectre to temporarily remove their powers, thus eliminating the potential threat they may have posed otherwise. This tactic allows them to distract the entity while Batman disables it with extreme cold.[11] This version of Starro returns and is revealed to be a scout for a much larger member of the species called the "Star Conqueror". Covering Europe with its body, the entity gains control of the minds of most humans while they sleep. Dream of the Endless aids the JLA in battling the entity psychically in a shared dream; simultaneously, a small team of heroes attacks its physical form. Assisted by a homeless man resisting the entity's control, the heroes free mankind from the alien's influence. Dream captures the Star Conqueror and stores the entity with his other keepsakes.[12]
In the 2005–2006 "Infinite Crisis" storyline Starro appears as a member of Alexander Luthor, Jr's Secret Society of Super Villains.[14] Starro eventually returns to Captain Carrot's universe to spark a conflict between aquatic and terrestrial creatures. Despite the efforts of the Zoo Crew, Starro floods the planet and defeats the heroes, who are then magically transported to safety with other surviving refugees by another animal team, Just'a Lotta Animals. Zoo Crew member Pig Iron battles Starro underwater, sacrificing himself as the rest of the heroes escape.[15]
In R.E.B.E.L.S., a new incarnation of Starro is introduced. This version is Cobi, a Hatorei alien from the planet of the same name.[16] After the Star Conquerors invaded his planet, Cobi fell under their control and worked with them to expand their empire.[17][18]
An alternate universe incarnation of Starro, amalgamated with Krypto, appears in JLA: The Nail.[20]
An alternate timeline incarnation of Starro appears in Booster Gold vol. 2.[21]
During the Justice League: No Justice event, one version of Starro sacrifices itself to protect the universe from the Omega Titans.[22][23] However, Batman preserves part of it which grows into a new individual dubbed "Jarro".[24][25][26]
Starro is an alien conqueror with a humanoid central mind commanding spores that resemble either giant or small Terran starfish. An asexual creature, Starro's spores are capable of generating clones that act in accordance with the original's will. The clones are parasites by nature and can attach themselves to a humanoid's face, and subsequently take control of the host's central nervous system, thereby controlling the host. Control of the host is lost once removed from the victim. Originally the first Starro could transform two Earth starfish into duplicates of itself equal to it in size and power.[28]
Both variants of the parasite are capable of energy absorption/projection, flight, changing color and self-regeneration, while the larger ones have a high degree of invulnerability as well as telepathy; the giant Starro possessing much more potent mental capabilities is able to indirectly influence the minds of a potential host race, capable of lulling countless people into an induced slumber and accessing their thoughts via dreams.[29] Another of the original Star Conquerors possessed psychic abilities powerful enough to overwhelm and circumvent the willpower of Hal Jordan to prevent access to his Lantern Ring's abilities.[30] Their size can also vary from being as big as city blocks to larger than a small planetary ocean body, in which case said Starro probe can radically alter the very climate, topography, and geography within its vicinity akin to terraforming. A future Starr Conqueror spore eventually came to weaponize five Qwardian power rings on its pointed tentacles; the rings could create objects based on the wielder's thoughts, but only those fueled by fear instead of willpower. Given the difficulty in their usage, Starro's capacity to use five at once indicated a mastery of the fear element and its usage in battle, as shown when it went up against multiple iterations of Titans all at once.[31] The latest version of the Star Conqueror shows how it uses its parthenogenesic capabilities to breed microscopic clones of itself, which can be inhaled by potential victims, serving as a catalyst to affect the giant iteration's telepathic abilities.[32]
The humanoid Starro possesses superhuman durability and telepathy and can transform Earth starfish into Starro spores.[33]
Starro appears in the Batman Beyond two-part episode "The Call", voiced by Christopher McDonald via Superman. While in captivity, Starro spent years plotting to take over Earth before taking control of Superman and infiltrating the Justice League. However, the alien's plot is foiled by Batman before Aquagirl and Big Barda send Starro and its offspring back to their home planet.
Starro appears in Batman: The Brave and the Bold, voiced by Kevin Michael Richardson (original form) and by Dee Bradley Baker (titan form).[34][35] Throughout the episodes "Revenge of the Reach!", "Clash of the Metal Men!", and "The Power of Shazam!", several Starro parasites come to Earth and take control of most of Earth's heroes while the alien's herald, the Faceless Hunter, eliminates anyone who Starro could not possess. In the two-part episode "The Siege of Starro!", the primary Starro launches an invasion with its thralls, but Batman, Booster Gold, Firestorm, B'wana Beast, and Captain Marvel join forces to defeat it and free their allies. In response, the Faceless Hunter kidnaps B'wana Beast and forces him to combine the Starro parasites into one giant Starro. After Batman defeats the Faceless Hunter, B'wana Beast sacrifices himself to separate the Starros.
Starro's species appear in Young Justice. Chronologically, they first appear in flashbacks depicted in the third and fourth season episodes, "Evolution" and "Teg Ydaer!" respectively, in which Klarion the Witch Boy summoned them to Earth to conquer it at the beginning of human history before they were repelled by Vandal Savage, though one Starro was frozen in ice. Throughout the first season, Atlantean scientists discovered the frozen Starro in the present. Black Manta and a group of mercenaries attempt to steal it for the Light, but are thwarted by Aqualad and Garth. In retaliation, Manta destroys Starro before it can be thawed, but a small piece is later recovered and sent to S.T.A.R. Labs for study. Sometime later, Light members Sportsmaster and the Riddler steal the sample so Klarion, Professor Ivo, and the Brain can infuse with it with technology and magic to create Starro-Tech, which their sleeper agent Red Arrow uses to brainwash the Justice League on Savage's behalf. Before the Team eventually rescues the League, Savage has six Leaguers attack the planet Rimbor to remove them from Earth during the events of the second season.
Starro is alluded to in the Smallville episode "Prophecy" via a device that the organization Marionette Ventures uses to control Stargirl and Lois Lane.[citation needed]
Starro appears in The Suicide Squad.[37] This version is capable of growing larger and more powerful depending on the number of thralls it possesses or consumes. Additionally, its control is permanent, with the hosts dying as soon as its spawn attach to their faces. Thirty years prior, Starro was captured by American astronauts and transferred to a Corto Maltesean research facility called Jötunheim, where the local and U.S. governments secretly collaborated to fund and oversee the Thinker's experiments on Starro using enemies of the Corto Maltesean regime in what would be called "Project Starfish". In the present, Amanda Waller sends the Suicide Squad to destroy Starro before it can be weaponized by Corto Maltese's new anti-American regime and to conceal the U.S.'s role in the project. After the team accidentally release Starro, it kills the Thinker in retaliation for experimenting on it. Upon escaping, it enslaves Corto Maltesean citizens and soldiers before being killed by the squad and a swarm of Corto Maltese's rats controlled by squad member Ratcatcher 2.
Starro makes a cameo appearance in the Batman: Arkham Knight DLC "A Matter of Family". This version was meant to be part of a sideshow act for Seagate Amusement Park before it was abandoned.
