1. The Brotherhood of Steel

The Brotherhood of Steel stands as one of the most iconic factions in the Fallout universe, and their portrayal in the TV series remains faithful to their game counterparts. This technocratic paramilitary organization operates on a medieval-inspired hierarchy with Squires, Knights, Paladins, and Elder Leadership forming their command structure.

Origins and Philosophy: Founded by American soldiers from the Mariposa Military Base shortly before the Great War of 2077, the Brotherhood believes technology caused humanity’s downfall and therefore only they are worthy of safeguarding advanced technology. Their philosophy has evolved from protecting humanity to gatekeeping technological progress, treating outsiders with suspicion and often hostility.

TV Series Portrayal: In the Amazon series, we follow Maximus, a Squire who dreams of becoming a Knight. After his Knight Titus dies in battle, Maximus takes his Power Armor and identity, eventually earning his Knighthood during the Battle of Griffith Observatory in Season 2. The Brotherhood’s T-60c Power Armor and rigid hierarchy remain central to their identity, showcasing their blend of ancient traditions with advanced technology.

Key Differences from Games: While the games feature multiple Brotherhood chapters operating independently, the TV series focuses on a single chapter, maintaining consistency with their established lore while streamlining the narrative for television audiences.

2. Vault Dwellers

Vault Dwellers represent the social heart of the Fallout TV series, with our protagonist Lucy hailing from Vault 33. Unlike the military-focused Brotherhood, Vault Dwellers form a social faction shaped by generations of isolation and controlled experimentation.

Origins and Structure: The series primarily focuses on Vault 33, which is interconnected with Vaults 32 and 31 in a complex social experiment called “Bud’s Buds.” This system was designed to create generational Vault-Tec loyalists who would eventually control the surface world. Vault 32 and 33 trade resources and intermarry, while Vault 31 supplies Overseers to maintain control.

TV Series Portrayal: Lucy’s journey from the naive Vault Dweller to wasteland survivor forms the core narrative arc of Season 1. The series reveals that Vault Dwellers were raised to believe the outside world was barbaric and uninhabitable, part of Vault-Tec’s psychological experiments to study human behavior under isolation and scarcity.

Notable Vaults Featured:

• Vault 33: Primary setting, home to Lucy and her family
• Vault 32: Connected to Vault 33, used for trade and marriage
• Vault 31: Contains cryogenically frozen Vault-Tec executives
• Vault 4: Former experimental vault now inhabited by mutant survivors
• Vault 24: Introduced in Season 2, contains disturbing experiments

3. New California Republic (NCR)

The New California Republic represents the largest and most organized democratic government in the post-war world, though the TV series reveals their tragic decline by the time of the show’s setting.

Origins and History: Founded by survivors from Vault 15, the NCR established Shady Sands as their capital and modeled their government after pre-war American democratic ideals. They’ve been a major faction since the first Fallout game in 1997 and played a central role in Fallout: New Vegas.

TV Series Portrayal: The show expands on NCR lore, revealing that sometime after the events of Fallout: New Vegas in the 2280s, Vault 33 Overseer Hank MacLean bombed Shady Sands. This devastating attack decimated the NCR, reducing their numbers and forcing them to operate from a new base at Griffith Observatory under Lee Moldaver’s leadership.

Current Status: By the time of the TV series, the NCR is a shadow of its former self, with Lee Moldaver’s death in the Battle of Griffith Observatory further weakening their position. However, loyal NCR members still exist, including Surface Dweller refugees in Vault 4 who maintain a classroom tribute to Shady Sands and practice religious worship of Moldaver as the “Flame Mother.”

4. The Govermint

The Govermint represents the fragmented nature of post-war authority, showing how law and order survive in pieces across the wasteland.

Structure and Philosophy: Unlike the organized NCR, the Govermint is an unorganized authority system with no unifying leader. Different regions have their own authority figures, including sheriffs, officials, and small administrations trying to enforce law and order in their own ways.

TV Series Portrayal: Sorrel Booker serves as one self-proclaimed president of the Los Angeles wastes, operating with sheriff enforcers named Rex and Troy. The Govermint maintains a wanted poster for Lee Moldaver, referring to her as the “Flame Mother.” The Ghoul (Cooper Howard) has some connection to Booker, suggesting a complex history that may be explored in future seasons.

Criminal Connections: The Govermint’s partnership with an organ dealer group operating out of a Super Duper Mart suggests that Booker functions more as a crimelord than a legitimate political leader, using the facade of government authority to further his criminal enterprises.

5. Pre-War Resistance (Hollywood Group)

This pre-war resistance faction represents one of the TV series’ most unique additions to Fallout lore, revealing that opposition to Vault-Tec existed before the bombs fell.

Origins and Leadership: Led by Lee Moldaver (then known as Williams), this resistance group consisted of Hollywood creatives including writers, filmmakers, and industry insiders who discovered Vault-Tec’s true intentions. Moldaver was a scientist advancing cold fusion research until Vault-Tec acquired her company as part of their monopoly goals.

Activities and Goals: The group gathered at Hollywood Forever Cemetery to expose Vault-Tec’s plans and prevent the coming apocalypse. Their efforts ultimately failed, but Moldaver mysteriously survived for hundreds of years without becoming a ghoul, suggesting she may have access to advanced technology or treatments.

Connection to Main Plot: This pre-war resistance directly connects to the main storyline, as Moldaver’s fight against Vault-Tec continued into the post-war world, eventually leading her to lead the NCR remnants and oppose Hank MacLean’s Vault-Tec agenda.

6. The Enclave

The Enclave serves as one of the Fallout universe’s most unambiguous villain factions, representing the worst aspects of pre-war American government and corporate power.

Origins and Ideology: Descended from the pre-war U.S. government’s shadow government, the Enclave considers themselves the only “true” humans and the rightful inheritors of the United States. They’ve committed numerous war crimes both before and after the Great War, including human experimentation and attempts at genocide.

TV Series Portrayal: In the series, we primarily encounter the Enclave through Dr. Siggi Wilzig, a former Enclave scientist who escaped their clutches. The Enclave conducts inhumane experiments on both humans and animals, maintaining their reputation as one of the wasteland’s most evil factions. Their appearance is limited in Season 1 but is expected to expand in Season 2.

Unique Power Armor: The Enclave possesses its own distinctive style of Power Armor, different from the Brotherhood’s T-60c models, showcasing their advanced technological capabilities despite their reduced influence in the post-war world.

7. Vault-Tec And Ally Corporations

Vault-Tec stands as the primary antagonist force across the Fallout universe, and the TV series reveals their central role in causing the Great War.

Corporate Conspiracy: The Season 1 finale reveals that Vault-Tec started the Great War to advance their agenda of creating a “new world utopia” under their control. The vaults were never meant to save humanity but rather serve as experimental laboratories to study human behavior under various conditions.

Allied Corporations: Vault-Tec’s corporate allies include:

• RobCo Industries: Led by Mr. House, teased at the series end
• Big MT (Big Mountain Research and Development Center): Known for bizarre experiments
• West Tek: Created the Power Armor used by the Brotherhood and researched the FEV virus
• REPCONN: Aerospace company specializing in rocket technology

Current Influence: Though the original corporate leaders are long dead, Vault-Tec’s influence persists through cryogenically frozen executives in Vault 31 and loyalists like Hank MacLean, who continues to work for the company’s goals in the post-war world.

8. Raiders

Raiders represent the most common and chaotic threat in the Fallout wasteland, serving as the primary antagonists for much of the TV series.

Nature and Organization: Unlike their purely chaotic portrayal in the games, the TV series’ Raiders show more calculated organization. While they still plunder and kill indiscriminately, they also collaborate with other factions to achieve specific goals, making them more dangerous than their game counterparts.

TV Series Portrayal: The Raiders demonstrate their brutality during Lucy’s wedding in Vault 33, where they disguise themselves as Vault 32 dwellers and massacre the inhabitants. They work with Lee Moldaver to kidnap Overseer Hank MacLean, using drugs like Jet to enhance their strength during the assault.

Cultural Practices: The series shows Raiders engaging in cannibalism and other extreme violence, establishing them as one of the wasteland’s most feared groups despite their lack of centralized organization.

9. Caesar’s Legion

Introduced in Season 2, Caesar’s Legion represents a unique imperialistic approach to rebuilding civilization, modeled after ancient Roman society.

Origins and Philosophy: First appearing in Fallout: New Vegas, Caesar’s Legion models itself after imperial Rome rather than the democratic ideals of the NCR. Their primary goal is the conquest of tribal communities across the American Southwest.

TV Series vs. Games: The TV series portrays Caesar’s Legion somewhat differently from the games. While the games present them as a disciplined, dangerous military force, the show depicts them with more comic relief elements, suggesting they’re not as effective or intimidating as their game counterparts.

Current Status: Despite their reduced threat level in the show, Caesar’s Legion remains active in the wasteland, representing an alternative to both the NCR’s democracy and the Brotherhood’s technocracy.

10. The Great Khans

The Great Khans represent one of the oldest factions in the Fallout universe, combining Native American aesthetics with biker gang culture.

Origins and History: Descended from Vault 15 survivors, the Great Khans originally targeted Shady Sands for raids, believing they had a right to its resources due to their shared origins. They’ve faced multiple extinction-level events but always survived, explaining their continued presence in the Fallout TV series timeline.

Cultural Identity: The Khans blend Native American and biker gang aesthetics, creating a unique visual style that sets them apart from other factions. They’re heavily involved in drug manufacturing and distribution across the American Southwest.

TV Series Introduction: Season 2 introduces the Great Khans to the TV series, showing their continued existence and adaptation to the changing wasteland dynamics. Their presence adds another layer of complexity to the faction landscape, offering viewers insight into how tribal societies have evolved in the post-war world.

Additional Factions and Groups

While the main 10 factions form the core of the TV series, several smaller groups and communities play important roles in the story:

Filly

A trading community built on a repurposed landfill in the greater Los Angeles area, Filly operates on purely transactional principles. Similar to Megaton from Fallout 3, it’s one of the first surface communities Lucy encounters, featuring shop owners like Ma June who help protagonists for the right price.

Vault 4 Residents

The inhabitants of Vault 4 represent a unique success story in the wasteland. Originally subjects of Vault-Tec’s DNA-splicing experiments, the mutant hybrids overthrew their captors and now maintain a surprisingly kind and supportive community. They also house NCR loyalist refugees who survived the Shady Sands bombing.

Wildcards

Independent characters like The Ghoul (Cooper Howard) operate outside traditional faction structures, motivated by personal goals rather than group ideologies. These wildcards reflect the player characters from the games, maintaining the series’ theme of individual choice and agency in a structured world.

Faction Relationships and Conflicts

The Fallout TV series excels at showing how these factions interact and conflict with each other:

• Brotherhood vs. Enclave: Technological supremacy rivalry
• NCR vs. Caesar’s Legion: Democratic vs. imperial ideologies
• Vault-Tec vs. Pre-War Resistance: Corporate control vs. freedom
• Raiders vs. Everyone: Chaotic violence against organized society
• Govermint vs. NCR: Competing claims to legitimate authority

These conflicts drive the plot forward and create the complex political landscape that defines the Fallout universe.
