Others
- The Hive Queen is the physical embodiment of the central consciousness of the Formics.
- Jane is an artificial sentience thought to exist within the ansible network by which planets communicate instantly across galactic distances and instant communication is made possible through the hundred worlds.
- Anton is a scientist of European descent who discovers two genetic modifications which will allow the human brain unlimited growth, at the cost of unlimited physical growth. This discovery, Anton's Key, is named in his honor. However, research into human genetic engineering was outlawed by the international community, and when the nature of his work was discovered, he was subjected to classical conditioning to make it difficult for him to continue or even discuss his research.
- Volescu is an unethical scientist of European descent, and the brother of Bean's father. He illegally modified 23 human embryos, "turning" Anton's Key within them; only one, Bean himself, was ever grown to maturity. Volescu was later discovered and had to destroy all his "research," but Bean escaped him by, at the age of 9 months, hiding himself in the tank of a toilet. Volescu was later imprisoned for his crimes.
- Poke is an orphan girl from the streets of Rotterdam, the leader of a "crew" of fellow orphans who eventually take in Bean—and Achilles. Poke gave Bean his name, which he was originally unfond of, but later recognizes himself as Bean and ignores Colonel Graff, who tells Bean his true identity as Julian Delphiki. In Rotterdam, Bean, on some instinct, tells Poke to kill Achilles when she has the chance; she refuses, and Achilles later kills her, after kissing her, by stabbing her in the eye and then throwing her in the Rhine. Bean witnessed the kiss in the dark and, after leaving the scene, came to the realization that Poke was unsafe. He rushes back to find Poke already dead; Bean then blames himself for Poke's death. When Bean tells the story of Poke to Ender's jeesh on the journey to Eros, he decides to trust Petra, saying to her, "You cried for Poke, and that makes us friends."
- Sister Carlotta is a Catholic nun who works as a recruiter for Battle School. Like Poke, she takes in both Bean and Achilles; however, her battery of psychological tests manage to identify Achilles for who he truly is. Later, when he escapes from a mental institution in Belgium and begins his reign of terror, she and Bean go undercover to oppose him, eventually linking up with Peter Wiggin. She, like Poke, meets her death at Achilles' hands; Bean is never able to forgive himself for these deaths.
- Stilson is a bully in Ender's Game. In the very first chapter of the book, he and three friends gang up on Ender, who decides to win, not just this fight, but all fights that might happen in the near future. Ender's counterattacks are so effective that Stilson, unbeknownst to Ender, suffers enough injury to later die in the hospital.
- Descoladores are a possibly sentient species that are first presented in Children of the Mind. Little is known about them other than the fact that they communicate using genes, through a virus, known as the Descolada, and that they can use that virus to alter the genes of all life on a planet, causing mostly lethal mutations. There has been much debate as to whether the Descoladores are Ramen, or whether Xenocide needs to occur (although the end of Children of the Mind lets us to know that the protagonists have decided to be Ramen themselves, and not use the Little Doctor to kill them all). It is suspected that they created the Descolada and other viruses in order to 'terraform' (to their liking) planets such as Lusitania. Upon arriving at their home planet, a group of scientists led by Miro, Jane, Quara, and Ela broadcast the remains of the Descolada found on Lusitania. This molecule contained the genetic makeup of all life on Lusitania (including humans and Pequeninos), although they did send an earlier version of the virus that had not seen the attempts to overcome it. The Descoladores responded by transmitting a genetic molecule back that affects the same place in the brain as heroin. Differing hypotheses for this transmission included a pacification attempt by the Descoladores to sedate and capture the intruders, as well as a welcoming "hug" to a new species. This led to the belief that the Descoladores communicate by transmitting a molecule meant to be manufactured and ingested by the receiving party. Another hypothesis is that this is the way the Descoladores communicate with animals, perhaps using philotic twining to communicate amongst themselves.
