Robert "Bob" Johansson
An engineer and programmer who got lucky with a sudden influx of cash from a buyout, unlucky with a sudden car crash, and very lucky that he had just signed onto a cryostorage company. The original Bob is dead, but all digital copies remember being him.
- The Aloner: He finds interacting with other people to be largely annoying. Bobs can go for decades alone without any real trouble, though they usually break down and build a clone eventually. Mario got a double dose of this trait.
- Small Reference Pools: Lots of nerdy sci-fi, not much else. Of course, since the people the Bobs talk to the most are other Bobs, they always understand all their references.
A fully artificial AI assistant given to Replicants to aid them.
- Artificial Intelligence: An autonomous (if not very imaginative) intelligence designed to essentially give replicants the calculation abilities that they lack, since they're not true AIs. GUPPI is the one who originally interjects in Bob's thoughts with precise numbers and measurements whenever he thinks of things in vague terms, until he orders it to stop and only respond to spoken commands.
- Shout-Out/ Expy: Soon after Bob leaves Earth, he changes GUPPI to look like Admiral Ackbar. The audiobook narrator even does a good imitation of his voice!
Bob-1 Johansson, HEAVEN-2
The Bob who first left Earth. After surviving an attack in Epsilon Eridani, he makes more clones, then goes off to Delta Eridani alone.
- Cargo Cult: He accidentally starts the first religion on Delta Eridani when he helps the Deltans fight the gorriloids. He's upfront about his abilities, so most of the more intelligent members of the tribe just treat him as a powerful ally, but some of the others start building shrines.
- Cloning Blues: When his original core is destroyed and he is restored from backup, he spends a few minutes considering the nature of his existence, before deciding that he is similar enough to the original Bob to still be considered Bob.
Marvin Johansson, HIC17378-1
One of Bob's Bobs in Delta Eridani. He helps catalogue the Deltans and their behaviors, often stepping in with advice about production of observation drones and busters.
- The Quiet One: Not as much as Mario, but he tends to keep quiet unless he absolutely needs to speak up. Bob often forgets he's there.
Riker "Will" Johansson
The very first of Bob's clones. He went back to Sol with his clone, Homer, to see if there were any survivors.
- Beleaguered Bureaucrat: Dealing with the survivors on Earth is not an easy job.
- Deadpan Snarker: Generally the straightman, but he has a reserve of wit.
- Pragmatic Hero: Riker is very blunt, just like his namesake. This causes problems when trying to negotiate with the survivors in Sol, and Homer has to make deals behind his back to keep him from starting another war.
Riker's first clone, built in Epsilon Eridani. He is a clown and a jokester, and grates on Riker constantly. Despite that, he was more than happy to go back to Sol with him.
- Class Clown: He got a double dose of Bob's humor, to the point that he even uses a cartoon avatar of Homer Simpson for a while, until Riker gets him to stop. However, when the chips are down, Homer is very reliable.
- The Gadfly: Looks to be a significant chunk of his relationship with Riker. He was just as adamant about going back to Earth to make sure everyone was okay, despite not getting along with Riker at all. Riker was confused and irritated by Homer's choice of Homer Simpson as an identity/avatar, because original!Bob found the character grating. And Riker got a lower sense of humor, more seriousness than most Bobs.
- The Social Expert: The Bobs aren't particularly social, so his ability to make people like him is invaluable. He even goes behind Riker's back and gets a deal with Spitsbergen and the USE, which Riker was too blunt to consider.
One of Riker's clones, built in Sol. He is significantly more negative than most of the other Bobs, which Riker finds annoying. But when the chips are down, he does a good job.
- Dropped a Bridge on Him: He triggers a nuclear trap while exploring the system and is destroyed. We never even find out where the trap came from; it could have been a remnant from the war or an attack by VEHEMENT.
- The Eeyore: Namechecked; Riker semi-accidentally calls him Eeyore a couple times. He always points out the worst parts of any situation, except when things are at their worst and everyone can see what's wrong.
Bob's second clone. A malfunction with his SUDDAR array gave him some interesting data, so he volunteered to stay behind in Epsilon Eridani and terraform Ragnarok, where he would have time to research.
- The Smart Guy: He comes up with several important inventions for the other Bobs, from observation drones, to a robotic avatar, and even a Subspace Ansible. The last is the most important, and will eventually link all Bobs together perfectly. But unfortunately, it takes decades to get the plans to the other Bobs in the first place, so by the end of the first book Riker's cohort is the only one he is linked with.
Bill's first clone. He decides to stay in Epsilon Eridani to help with research and terraforming.
- The Igor: He accuses Bill of treating him this way, using him as an assistant and never listening to his advice. Bill relents, and Garfield's more cautious style proves helpful when moving the ice to Ragnarok.
Bill's second clone. He leaves for Alpha Centauri with Goku, despite the fact that they are constantly at each other's throats.
Bill's third clone. He leaves for Alpha Centauri with Calvin, despite the fact that they are constantly at each other's throats.
Bill's fourth clone. He leaves for Epsilon Indi alone, not wanting to wait for another clone or to pair up with either Calvin or Goku.
- Pet the Dog: He saves the Australian replicant and builds him a VR sim, when it would have been simpler to just kill him and scavenge his wreck.
Bob's third clone. He eagerly leaves for for Omicron2 Eridani, the supposed home star of the Vulcans.
- The Knights Who Say "Squee!": He jumps at the opportunity to go to the Vulcan home star. When he discovers twin worlds, he immediately names them Vulcan and Romulus.
Bob's fourth clone, and by far the most antisocial. He leaves for Beta Hydri, a relatively distant star, so as to stake his claim early.
- The Aloner: As Bob put it, "He makes Guppy look like a social butterfly." Ironically, Guppy quickly becomes Mario's only friend once Mario gives him enough memory to grow as a person.
- The Quiet One: He barely speaks to the other Bobs in Epsilon Eridani, and doesn't seem particularly concerned when he can't create a communications station in Beta Hydri.
The man in charge of training Bob and ensuring the success of the project as a whole. He is friendly and amenable, and acts much like how Bob would expect someone from the 21st-century to act.
- Dropped a Bridge on Him: He gets killed in a bombing shortly after Bob leaves Earth. Bob doesn't even get to say goodbye.
- Eternal English: Subverted. He was specifically trained to speak in a dialect that Bob would find familiar.
- Reasonable Authority Figure: While he works for FAITH, he's not a theocrat. He empathizes with Bob's plight, and warns him about the loyalty switches and kill triggers hidden in his code.
The ambassador of the FAITH survivors on Earth once Riker returns. He is initially angry and demanding, but proves reasonable once all other options are exhausted.
- Just a Machine: Constantly refers to Riker as "replicant," orders him to give special consideration to FAITH, and tries to use the secret command override. Of course, all that does is get him ignored.
- Reasonable Authority Figure: After his attempts to control Riker fail, he puts forth a reasonable plan to help other survivors in exchange for special consideration. It's implied that Homer suggested it, but either way it's a real turn around.
Major Ernesto Medeiros, BES Serra do Mar
The replicant in the Brazilian probe. He is a ruthless military mind who has decided that the best way to colonize the stars is to kill all the other probes.
- Axe-Crazy: He is very much of the "shoot first, ask questions never" mindset. It's not just that the Bobs are FAITH ships, either; he killed the USE probe without any signs of discussion.
- Boring, but Practical: He's not an engineer or a programmer, but he is an excellent tactician and a ruthless soldier. He is able to set several ambushes for Bobs using unexpected tactics, including secret Brazilian projects he was keeping in reserve.
- Undying Loyalty: He keeps fighting for the Brazilian Empire long after the Brazilian Empire is no more. Of course, if he has similar loyalty switches as the ones FAITH put in Bob, he might not have a choice.
- We Have Reserves: He has this attitude towards himself and his clones. While this attitude is inevitable to a point, he occasionally leaves his clones behind unprotected with nothing but a 3D printer.
Captain Matias Araújo
A Brazilian replicant left behind in the Sol system. He was uploaded to a number of gunships rather than probes, so he has no real manufacturing capability, but he is the last military force standing in Sol.
- Axe-Crazy: He makes Medeiros look sane, spitting vitriol and trying to render the Earth uninhabitable out of spite.
- Undying Loyalty: Like Medeiros, he keeps fighting even after it's clear that the Brazilian Empire has lost. In his case, he's willing to render the entire Earth uninhabitable—killing numerous Brazilian survivors—to get the last blow against China, who killed Brazil.
United States of Eurasia
Colonel George Butterworth
The highest-ranking member of the USE still alive, and in charge of a large group of refugees on Earth. He is the first one to contact Riker after Riker diverts Araújo's asteroids, saving the planet.
- Reasonable Authority Figure: Although he and Riker often butt heads, he has a pretty strong bargaining position. He provided the plans for the colony ships, so his people should be the first to go. His biggest problem is that he gets mad about anything that seems to delay construction. Homer goes behind Riker's back to make a deal to delay the ships slightly so that the Spitsbergen ship can be built faster.
The Australian Federation
The Australian replicant. He was a fisherman before his mind was cloned, and he was chosen for his ability to last for a long time away from people. Unfortunately, once he was in space, he went insane from lack of stimulus.
- Go Mad from the Isolation: Between being locked in a ship with no real body and having no one to talk to, he goes crazy and his personality splits, switching between declaring himself "Emperor Mung of the Intergalactic Jalapeno Empire" and believing that he's a prisoner of said "Empire" under interrogation. Linus builds him a VR body, but lets him believe he's not a replicant for the meantime.
