Jim Holden

Jim Holden is the captain of the Rocinante, a former UN Navy officer from Earth who was born in Montana, United States. Holden was born to eight parents (five fathers and three mothers) as part of a "genetic collective" at a time when Earth's population was over 30 billion. Holden's story begins when he witnesses the destruction of the Canterbury at the hand of a Martian ship and spreads the word. The MCRN Donnager takes him and his crew captive, and demand he frame Naomi Nagata for the destruction of the Cant and tell her off as an OPA member so as to clear the Martian name. Instead, he escapes with his small crew, minus Shed Garvey after his death, when the Donnager destroys itself to avoid capture. They then rename their ship the Rocinante and acquire the help of military official Fred Johnson. The four vote unanimously to find Fred. When they arrive, they are provided with lodging after meeting Fred, who they begin to work for. Eventually, Holden and his team are given coordinates to one of the stealth ships that destroyed the Cant, where they find all the airlocks open and the decks depressurized, with only a "Lionel Polanski" escaping in a pod. This leads them to a hotel on Eros where they meet Joe Miller, who reveals that Polanski is really Julie Mao, the woman he has been searching for.

Holden and Miller are separated from the rest of the crew of the Rocinante and realize that the inhabitants of Eros are being infected with the protomolecule, the virus that killed Julie, and dosed with radiation to help it grow. He and Miller are able to make it onto the ship to get treated. In Caliban's War, he and his crew have worked for the Outer Planets Alliance for 18 months since what’s become known as the Eros Incident, and the job just doesn’t feel right. While assisting a botanist in the search for his daughter, Holden comes across signs that people are still trying to tame the protomolecule, and the threat comes very close to home. Breaking his OPA ties, he becomes an ever-more-important piece in the four-way chess game for who will run the solar system.

As the solar system prepares to mount its first large-scale exploration of the ring in the next book in the series, Abbadon's Gate, Holden’s interaction with the alien consciousness in the form of an old friend named Miller convinces him that he wants to be as far away from the ring as possible. Greater forces have other plans, however, and the crew finds themselves at the ring with fleets of Earth, Mars, and Outer Planet Alliance ships. In Cibola Burn, sensing trouble brewing on Ilus/New Terra, Chrisjen Avasarala sees the need for someone perceived as unbiased to negotiate and report on events there and chooses Jim Holden. After making the journey, the crew tries their best to balance colonial claims, government priority and the awakening creatures on the planet within a crisis greater than all their earlier concerns.

Sensing trouble brewing on Ilus/New Terra, Chrisjen Avasarala sees the need for someone perceived as unbiased to negotiate and report on events there and chooses Jim Holden. After making the journey, the crew tries their best to balance colonial claims, government priority and the awakening creatures on the planet within a crisis greater than all their earlier concerns. Still the captain of the Rocinante and increasingly competent and trusted negotiator and troubleshooter of the solar system, is back in the thick of things as a combined fleet of ships from Earth, Mars, and the Outer Planets Alliance fight the Free Navy and try to structure a new place for humanity in the universe. When the war is over, he is the one to suggest creating an organization made up of Belters that would control space commerce so they will still have a functioning economy. In Persepolis Rising, Holden looks to the next chapter of his life, retirement. When the Laconians return through the gate, Holden is drawn back in to the fray. While his companions all escape to lead the resistance against Duarte, he is taken back to Laconia as a captive.

A comic book revolving around Holden and detailing his past before Leviathan Wakes, written by James S. A. Corey, Hallie Lambert and Georgia Lee and illustrated by Huang Danlan, Triona Farrell, Juan Useche and Rahzzah, was released on February 1, 2017. Holden is the only character to be used as a viewpoint character in all eight novels. Ty Franck, one half of the Corey pen name, writes all chapters about Holden. In The Expanse television series, Holden is portrayed by Steven Strait and appears in all six seasons of the show. Strait was cast in August 2014. Franck and Abraham have said that Holden is "holy fool. He’s an idealist, a man who faces things with this very optimistic view of humanity.  He believes that if you give people all of the information, they’ll do the right thing with it because people are naturally good." Amy Wilhelm of Book Club Babble has praised the television series, as well as the character of James Holden, saying: "All in all, the casting and the writing is well done. Although his physical characteristics don’t exactly scream grew up on a farm in Montana, Steven Straight’s ability to show Holden’s cockiness, uncertainty, intelligence, and thoughtfulness all through his varied facial expressions is dead on."

Joe Miller

Joe Miller is a Belter who worked as a detective for the Ceres station security firm, Star Helix Security. While working with his partner, Dmitri Havelock, Miller is hired to find Juliette "Julie" Andromeda Mao, who has disappeared in the book's prologue. Over the course of the first book in the series, Leviathan Wakes, Miller discovers that Julie was on the Scopuli, which was used as bait when it sent out a distress beacon that was picked up by the Canterbury, however this was a ruse for a seemingly Martian ship to destroy the Cant. He connects the dots, discovering that Julie was in fact connected to the Cant's destruction, as she was the only survivor on the Scopuli at the time, however, after investigating and angering Anderson Dawes, who is known OPA, he is suddenly fired from Star Helix Security by Captain Shaddid, who is in Dawes' pocket. Miller continues looking for Julie, even developing a sort of a crush on her. He goes to Eros and meets Jim Holden and his crew of the Rocinante, who are looking for a "Lionel Polanski", revealed to be a name used by Julie. Miller discovers that Julie has died of something called the protomolecule and is then infect with the virus and dosed with radiation to help it grow. As everyone on Eros has the same thing happen to them, Miller and the other five members of the Rocinante crew escape and Miller is treated, though everyone on the station is killed. Miller invades Thoth station and finds Antony Dresden to get answers, but later kills Dresden for his actions against Eros Station. Holden blames Miller for killing Dresden, until they make up and Miller sacrifices himself after meeting a still-alive Julie inside the Protomolecule. Miller dies helping crash Eros into Venus to destroy the Protomolecule, but it instead just begins reassembling into a new form.

Miller's consciousness continues on in disembodied form in Abaddon's Gate, now part of the vast protomolecule matrix and used for his investigative capabilities. Talking to and trying to work with James Holden, he has limited insight into the actions taken by the gate, and knows there is a vast tapestry of opportunity and danger associated with it and those who built it, because someone destroyed them. In Cibola Burn, Miller is still trying to figure out his role within the alien construct, while maintaining his connection with Holden. Eventual clues come together allowing him to shut down the alien machinery and potentially save everyone. However, both the remnants of Miller and the Investigator are killed in the process.

The chapters involving Miller are written by Daniel Abraham, one half of the Corey pen name. In The Expanse television series, Miller is portrayed by Thomas Jane and appears the first two seasons of the show, with special appearances in the third and fourth after the character's death. Jane was cast in the role in August 2014, along with Steven Strait as James Holden and Shohreh Agdashloo as Chrisjen Avasarala. Corey has said that it was apparant upon the character's creation that Miller was a "classic noir character". Corey also called Miller a "cynic and a nihilist" and said that "He looks at the dissemination of information as a game you play. He doesn’t have faith in anyone else’s moral judgment. Control of information is how you get people to do what you want, and he doesn’t trust anyone else to make that call".

He, especially in the first season, looks like the generic tough guy. And we had a bunch of people who auditioned for it who were playing generic tough guy. And Wes [Chatham] had actually read the novella that has Amos' backstory, and loved character, and understood the character coming in. Everybody else was coming in and looking gruff and mean and looking for a fight. Wes was just coming in and going, 'Yep. Ejecting you too.' It was perfect."

Carlos "Bull" c de Baca, a member of the OPA serving as chief security officer aboard the Behemoth. De Baca is given the job of third in command of the Behemoth, formerly known as the Generation Ship Nauvoo, which the OPA salvaged and repurposed as a warship. Not only is Bull absolutely loyal to Fred, he also is the most likely of the command crew to secure the mission's success, which is why Fred asks Bull to “make it work”. When Clarissa triggers her faked broadcast of James Holden, in which he claims responsibility for the sabotage of the Seung Un and to being ordered to do so by the OPA, Bull understands all the implications. He also understands that all of the human governments need to stand united in facing the alien ring and the possible threat coming from it.

In order to avoid another open shooting war/battle among Mars, Earth, and the OPA at all costs, he convinces the Behemoth's captain that being the first to take hostile action against the Rocinante will stop the Behemoth from being seen as Holden's backup, and distance the OPA from Holden's statement about 'claiming the ring' for them. After the Behemoth fires a Torpedo at the Rocinante, the other flotillas join by also targeting Holden's ship—forcing him to travel into the ring as an attempt to escape.

Marco Inaros

Marco Inaros, a commander of Free Navy, a radical OPA branch. Marco succeeded in knocking the old regime back on its heels. When the allied forces advance against him, he is forced to contend with the fact that, while the Free Navy has advanced military hardware, he and the other leaders do not have the tactical knowledge needed to properly fight navies led by professional officers. He attempts to make up for this shortcoming by pulling out of the Belt without fighting, forcing his enemies to expend their resources in a costly occupation, explicitly comparing the Free Navy to the Taliban. This does not work and the Free Navy is eventually destroyed by a combination of mutinies, desertion, battles with the inners, and its ships being consumed by the force in the gates.

The character is introduced in the beginning of the second season of the series, which adapts the second half of Leviathan Wakes, though in the book series the character is not established until the second book, Caliban's War. Abraham also called Bobbie one of the hardest characters to cast because "it was really important to us not to blink on keeping the ethnicity and background of the character true to the books. And there's just not a lot of folks like her in people's Rolodexes. We had to set up places in a bunch of places. Again, it wasn't just L.A., New York, see who you get. We had to go to Hawaii, and we had to go to New Zealand, we had to really push to get the right people to read for it. And then she came and read for it, and then it was easy. But it still was hard."

As of Abaddon's Gate, Jules-Pierre was part of various conspiring organisations, all of whom wanted to use the protomolecule for profit. He was brought down by James Holden in the events that occurred during and after the near-destruction of the Ganymede colony, a major food supplier for the outer planets of the belt.

• Namono "Nono" Volovodov, wife of Anna, with whom she has a daughter, Name. Raven Dauda portrays the character in the television series adaptation, appearing in a recurring role for the third season.
• Teresa Duarte a.k.a. Tiny, the daughter and heir of the High Consul. Duarte does not appear in the television series
• Paolo Cortázar, a former member of Protogen's nanoinformatics research division, he is now the lead researcher on Laconia. He was released by rogue members of the OPA, and has been working with the rogue Martian fleet under Admiral Duarte ever since. He is the lead researcher on Laconia and is working on making Duarte immortal using protomolecule technology. Carlos Gonzalez-Vio portrays Cortázar in the second and fifth seasons of the television series adaptation of The Expanse in a recurring capacity both times. Abraham has noted that Cortázar and Amos Burton have an interesting dynamic, saying "Amos and his rather odd psychology and background talk to each other a little bit in the plot ... those two characters have a lot to say to each other, and they just didn't wind up in the same place at the same time in the books."
• Santiago Jilie Singh, a captain in the Laconian Imperial Navy and commander of the Gathering Storm. The character does not appear in the television series adaptation.
• Anton Trejo, High Admiral of the Laconian Imperial Navy and captain of the Heart of the Tempest.
• Michio Pa, executive officer of the OPA ship Behemoth, later captain of the Free Navy ship Connaught. She joined the Free Navy because of Marco's promises to build a better, more prosperous society on the outer planets with resources stolen from colony ships. As the war continues, she tries to pressure Marco Inaros to negotiate a ceasefire so the rebuilding can begin. She repeatedly points out that there is a limited time frame in which the Belt and outer planets can create a self-sustaining economy to no avail. In the end, she and other members of the Free Navy desert.
• Basia "Baz" Merton, a welder from Ganymede, later citizen of Ilus. His ship pushed through the gate to be the first to settle a new planet. Called Ilus by the inhabitants, they found a rich vein of lithium that could provide a valuable trading commodity with other systems. The United Nations sends a scientific party to the planet with a legal charter to the land. This drives Basia to actions he never thought he would do, and it seems like he has a never-ending set of decisions between bad choices, while he's only trying to do what he thinks is best for his family.
• Winston Duarte is an admiral in the Martian Congressional Republic Navy, until he and a splinter group broke away from Mars and went through the ring gate to the planet Laconia. Duarte learned of Laconia and the vast amount of protomolecule technology that was left behind by the creators through his position at the MCRN, and felt that it needed to be acquired and understood, in the event that the race that destroyed the protomolecule builders returned. He sees himself as a Philosopher King who will lead humanity to victory over whatever destroyed the Protomolecule builders. To achieve this and avoid problems with succession he has begun treatments to make himself immortal. Duarte does not appear in The Expanse television series.
• Shadavir Errinwright is the UN Undersecretary of Executive Administration. In the television series adaptation, Errinwright's appearance is changed from the dark-skinned man with a round, soft face and a British accent he is in the books to light-skinned with an American accent, and he is portrayed by Shawn Doyle in a main capacity for the first three seasons.
