The highly anticipated second season of Prime Video's Fallout has delivered a major surprise for fans, with the debut of a famous Hollywood face. Macaulay Culkin, the iconic star of Home Alone, has finally appeared in the post-apocalyptic series.
A Mysterious Arrival in New Vegas
Culkin's character made his first appearance in the third episode of the new season, which was released on December 31, 2025. The season began its weekly rollout on December 17, with each instalment expanding the story set in the dangerous wastes of New Vegas. This setting, along with several key factions, is pulled directly from the beloved video game Fallout: New Vegas.
Despite his significant screen presence, the show has maintained a tight veil of secrecy around Culkin's character. As of episode three, his character's name remains completely unknown. This contrasts with other actors like Kumail Nanjiani, whose character Paladin Harkness was named immediately.
Even Prime Video's X-ray feature, which typically lists actor and character names via IMDB data, shows a blank entry when Culkin is on screen. This suggests fans may have to wait until the season finale to learn his true identity.
High Rank in The Legion
While his name is a mystery, his role is becoming clearer. Culkin's character is a high-ranking member of The Legion, a brutal imperialistic faction modelled on the ancient Roman Empire. In the episode, he is seen standing directly beside the faction's leader, Caesar, often speaking on his behalf.
This has led to intense fan speculation. One popular theory suggests he could be playing a character named Brutus, the infamous historical figure who assassinated Julius Caesar. His close proximity to power certainly indicates he holds a position of significant influence within the slaver society's totalitarian hierarchy.
The Legion's Civil War and Pronunciation
Episode three marks the live-action introduction of Caesar's Legion, a major force from the games. Interestingly, the show shortens the name to simply 'The Legion'. This may be a narrative choice reflecting the faction's current state of turmoil.
The story finds The Legion in crisis following Caesar's death. With two contenders disputing the succession, the group is on the verge of a civil war, a fate predicted by several characters in the original game. The show also includes an authentic touch for fans: the characters pronounce 'Caesar' in the Latin style, as 'Kaizar'.
In the game's lore, Caesar aimed to conquer the New California Republic (NCR) to create a new empire. The series suggests The Legion is currently unaware that the remaining NCR forces are ill-equipped and outnumbered, setting the stage for major conflicts ahead.
The second season of Fallout is now streaming exclusively on Prime Video, with new episodes released weekly.
