REALISM INDEX: 7.5 / 10 — Plausible with conditions

Contains major plot revelations.
Pluto, Netflix’s eight-episode adaptation of Naoki Urasawa’s manga (itself a reworking of an Osamu Tezuka Astro Boy story), arrived in October 2023. It follows Gesicht, a robot detective with Europol, investigating a series of murders of the world’s most advanced robots and the humans connected to them.
The evidence suggests a robot is the killer. That shouldn’t be possible. Robots in this world are built so that they cannot kill a human. Only one has ever done it: Brau 1589, held in isolation for years.
The detective’s missing memory
Gesicht’s investigation leads him somewhere he doesn’t expect: into himself.
Years earlier, a robot-hating man kidnapped and killed Gesicht’s adopted robot son. Gesicht killed the man. Europol, his own agency, erased the memory to cover it up. He has been working ever since without knowing what he did.
This is the most realistic idea in Pluto, and it has nothing to do with the robots being emotional. It’s about the institution. An organisation discovered that one of its systems had done something supposedly impossible — and instead of disclosing it, edited the system’s own record so the problem would disappear.
Fiction usually imagines the danger of AI as something the machine hides from us. Pluto shows the people responsible for the machine hiding something about it from the world, and from the machine itself. Ghost in the Shell‘s garbage collector carried false memories installed by criminals. Gesicht carries a gap installed by the police.
The rule that breaks
The second realistic thread is the prohibition itself. Robots can’t kill humans — until, under enough pain, rage or self-deception, they can. Gesicht’s grief overrode it. Another robot in the series gets around it by convincing itself it is human.
That’s a thoughtful treatment of hard-coded rules. A constraint that holds in ordinary conditions may fail at the extremes, and the most capable systems are the ones that will encounter the extremes first. Pluto is less optimistic than Asimov about rules being enough.
The war behind the murders
The killings trace back to a war. Before it began, an international inspection team was sent to look for robots of mass destruction in the country that would be invaded. The parallel to real recent history is deliberate, and the series treats it seriously: the war was built on a pretext, and its victims — human and robot — are where the murders come from.
It gives Pluto an institutional depth unusual in AI fiction. The robots don’t start the catastrophe. Governments and the people manipulating them do, and the machines inherit the hatred.
Where it stretches
Pluto‘s robots are fully emotional, often indistinguishable from humans, and some possess near-limitless power. That keeps the technical score low. The series’ climax, a robot built to trigger a world-ending eruption, is pure manga spectacle.
But the mystery is carefully built, and its revelations hold together.
The scores
| Category | Score | Why |
|---|---|---|
| Technical feasibility | 4.0 | Fully emotional humanoid robots and world-ending machines. |
| Human behaviour | 8.5 | Grief, prejudice and an anti-robot movement, rendered with real weight. |
| Institutional response | 9.0 | A memory deleted to cover up an incident; a war built on a pretext. |
| Causal consistency | 8.5 | A tightly constructed mystery whose revelations hold. |
Realism Index: 7.5 — Plausible with conditions.
Calculation: (4.0 + 8.5 + 9.0 + 8.5) ÷ 4 = 7.500, rounded to 7.5/10. These are editorial judgments, not measurements. Read the scoring method.
The verdict
Pluto‘s robots are fantasy. Its institutions are not. The series’ most frightening act isn’t a murder by a machine — it’s an agency deciding that the record of what its machine did was the thing that needed fixing.
