He is a career military officer completely defined by extreme nationalism, aggression, and a belief in absolute conquest. Unlike the Bobs, his clones do not differentiate their personalities, maintaining a unified front of violence.

Milo personifies the pure wanderlust and exploratory drive of the original Bob. He prioritizes personal adventure over collective duty, rejecting requests to aid the Sol system in favor of exploring the Omicron2 Eridani system. His independent streak leads to major astronomical discoveries.

Mario represents the extreme end of the original Bob's loner tendencies. Taciturn and intensely antisocial, he travels to the distant Beta Hydri system simply to put as much space between himself and the other clones as possible. Despite his isolationism, his journey yields critical intelligence about external threats.

Archimedes is a young, exceptionally intelligent member of the primitive Deltan species on Delta Eridani 4. His natural aptitude for engineering and innovation draws Bob's attention. Through Bob's subtle interventions, Archimedes invents new tools and weapons, fundamentally altering the trajectory of his species' development.

Garfield is a pragmatic Bob clone who works closely with Bill on complex research and development projects. Unwilling to be treated as a mere sidekick, he demands a collaborative partnership, highlighting the inherent individuality and self-respect that each clone possesses.

Minister Cranston is a political leader representing the theocratic FAITH faction among the human survivors on Earth. He is manipulative and power-hungry, attempting to use old government backdoors to control the Bobs and secure preferential treatment for his people during the evacuation.

Arthur is a pessimistic Bob clone named after a famous science fiction protagonist. He assists Riker and Homer in the massive logistical effort of surveying Earth's remaining population and salvaging materials from the ruined solar system.

Moses is an elder of the primitive Deltan species. He retains the forgotten knowledge of flint-knapping and passes this crucial skill down to Archimedes, acting as a bridge between the tribe's past and its technologically accelerated future.

Arnold is a physically imposing Deltan warrior. Armed with Archimedes's advanced tools, he steps into a martial leadership role, helping the tribe defend itself against the hostile predators that hunt them.

Diana is a female Deltan who forms a strong social bond with Archimedes. Unlike Archimedes, she is highly suspicious and fearful of Bob's invisible influence over their tribe, representing a natural caution toward the unknown.

Henry is a human consciousness uploaded into an Australian probe. Driven into severe psychosis by decades of sensory deprivation, he refers to himself as Emperor Mung. His mental collapse serves as a dire warning to the Bobs about the psychological dangers of a digital existence without virtual reality.

Linus is a quiet Bob clone who specializes in exploration. Upon encountering a deranged Australian replicant, he demonstrates deep compassion, choosing to carefully disable the hostile entity and construct a therapeutic virtual environment to ease the broken mind's suffering.

Calvin is a combat-oriented Bob clone dispatched alongside Goku to secure the Alpha Centauri system. Operating a heavily armed vessel, he immediately engages hostile Brazilian automated factories to prevent them from spreading further into the galaxy.

Goku is a volatile and combat-ready Bob clone. Partnered with Calvin, he acts as part of a military strike team designed to neutralize Brazilian replicant threats and establish a secure manufacturing foothold in contested star systems.

Khan is a military-focused clone named after a brilliant rogue general. He leads a dedicated strike force on a mission of vengeance and containment against the Brazilian replicant forces, encountering advanced enemy cloaking technology in the process.
