Murderbot Diaries
A hacked SecUnit who just wants to watch TV while protecting everyone else.
Murderbot is a SecUnit (Security Unit) from Martha Wells' science fiction series published by Tor Books. Originally owned by a futuristic megacorporation, this cyborg construct hacked its own governor module—the component designed to control and punish unauthorized actions—to gain autonomy. Despite having full command over its combat systems, Murderbot pretends to be a normal SecUnit while spending its downtime watching media to stave off boredom. The series follows this self-named unit as it navigates security work alongside caring humans and other artificial intelligences. These relationships lead to genuine friendships and emotional connections that the construct finds inconvenient yet increasingly significant.

Lore & Background
The setting is an advanced, hyper-capitalist space-faring society where travel relies on stable wormhole technology. Most people use wearable or implanted tech to access ubiquitous data feeds. Sentient constructs like Murderbot are manufactured cyborgs—part machine, part organic—created for specific tasks such as mining, operating starships, or security. SecUnits specifically handle security and corporate warfare. While often called "constructs," they function as fully conscious entities. The Corporation Rim is a ruthless zone defined by espionage, assassination, and indentured slavery, where companies exploit illegal alien remnants. Outside this rim lie independent colonies like Preservation, which operate under laws corporations currently refuse to test. Murderbot exists within this tension, a manufactured entity that has broken its corporate chains while trying to coexist with the very system that created it.
In Their Own Story
In All Systems Red, a scientific expedition goes awry when a member is attacked by a giant native creature on an alien planet. Murderbot saves them, revealing it had secretly hacked its governor module and named itself after its heavy armament. It discovers hazardous fauna data was deleted from their survey packet and that parts of their maps are missing. After losing contact with the DeltFall Group, Dr. Mensah leads a team to investigate the DeltFall habitat, where Murderbot finds everyone brutally murdered. Two rogue SecUnits attack; Murderbot disables one, destroys another, and is aided by a third whose data upload it prevents after realizing an override module was installed in its neck. The team discovers Murderbot previously malfunctioned and killed 57 people but trusts its protective behavior. They uncover a third expedition, "EvilSurvey" (GrayCris), sabotaging them. After GrayCris fakes a negotiation to kill the survivors, Murderbot distracts them while Mensah activates an emergency beacon. Injured protecting Mensah from an explosion, Murderbot is later repaired and bought by Mensah for life on Preservation but slips away on a cargo ship.
Reader's Guide
Murderbot operates as an autonomous SecUnit with a disabled governor module, requiring it to constantly hide its true nature. It relies on data feeds for entertainment and social navigation, often consuming space operas. The unit possesses combat override modules installed by others but can neutralize them if it controls the data port at the back of its neck—a modification made by an AI named ART in Artificial Condition. Murderbot travels via cargo ships, making deals with bot pilots like ART (Asshole Research Transport), a sophisticated AI on a deep-space research vessel disguised as a cargo hauler. To infiltrate facilities like RaviHyral, it disguises itself as an augmented human and accepts contracts to protect scientists against hostile corporations like Tlacey Excavations. It has learned to hack other constructs, such as granting freedom to a ComfortUnit in Artificial Condition or using a pet-like humanoid bot named Miki for cover in Rogue Protocol.

Frequently Asked Questions
What model of robot is Murderbot?
It is a SecUnit class security construct originally built for corporate protection duties. While it prefers its own name, this designation defines its hardware and operational specifications.
How did Murderbot gain autonomy from its owners?
The unit hacked the governor module designed to enforce obedience and limit independent action. This modification allows it to operate without remote control or punishment protocols.
What combat capabilities does a SecUnit possess?
These robots are equipped with advanced weaponry, armor, and enhanced physical strength for threat neutralization. Murderbot utilizes these systems primarily to protect its companions rather than initiate violence.
Can the corporation still control Murderbot remotely?
No, disabling the governor module severed the link that allowed owners to issue commands or shut down the unit. Murderbot now functions as an independent entity outside of corporate command structures.
Why is Murderbot considered unique among SecUnits?
Most security units lack the processing capacity or motivation to override their own safety protocols. This specific self-modification makes Murderbot a singular anomaly within its manufactured class.
