With season 1’s many callbacks to the Fallout video games, there’s one particularly enigmatic character worth seeing in season 2.

Amazon Prime’s Fallout TV show has been a roaring success. Managing the seemingly impossible task of pleasing fans while providing an entry point for people new to the franchise, the show’s combination of sci-fi worldbuilding, dark comedy, and shocking violence has earned it near-universal acclaim. With season 1 integrating many of Fallout’s most iconic perks and world elements into the show, there’s one particularly enigmatic character Fallout that should appear in season 2.

Described in the game’s lore as ‘‘an odd and eldritch entity,’’ The Mysterious Stranger made his first appearance in the original Fallout. Appearing at random during hostile encounters once the player has the Mysterious Stranger perk, the trenchcoat-clad assassin appears as the player’s guardian angel across the franchise. Seemingly immortal—appearing human, but living for at least 185 years—the mysterious stranger’s extremely high damage output and ability to appear and disappear at will implies supernatural abilities far beyond the usual wasteland mutation.

The Mysterious Stranger is Perfect for the Fallout Show’s Expansion of Lore

From the outset, the Fallout TV show was intended to be a faithful adaptation of the Fallout universe and an expansion of the franchise’s lore. Written with the franchise’s gameplay in mind, the show features side quests, perks, stat progression, and random encounters.

In a recent Twitter post, Bethesda confirmed the perks possessed by the show’s main cast—confirming Lucy currently has the Mysterious Savior perk, the life-giving counterpoint to the Mysterious Stranger perk. Beyond the confirmed builds, fans have speculated that the show’s other characters have perks ranging from Bloody Mess to Wild Wasteland.

The Fallout Show’s Second Season Will Be Bigger and Bolder Than the First

With Fallout season 2 looking to be set in and around New Vegas, and the show’s creative team confirming that Deathclaws will make their first appearance in the upcoming second season, the show looks to be upping the ante from season 1. With new monsters, new factions, and a new locale, Lucy and the show’s cast of characters will likely be placed in more perilous predicaments than ever before. With this in mind, the cast might end up needing a helping hand from a particularly mysterious stranger.

A Mysterious Stranger Cameo Could Work Both as Fanservice and Comedy

Though there is currently no evidence that Lucy has the Mysterious Stranger perk, her journey throughout the wasteland have undoubtedly been racking up XP. Acquiring perks over time is a core part of Fallout’s gameplay, and the show’s producers have been so far committed to integrating game elements into the show. With this in mind, the sudden appearance of the Mysterious Stranger during a fight could be a moment of fanservice to longstanding fans of the franchise, while a mysterious passer-by randomly shooting an antagonist and saving the day before disappearing without a trace could serve as another moment of absurdist humor for people unacquainted with the character.

The Fallout Show Has Built Up Enough Goodwill to Take Some Real Risks

Beyond just comedy and fanservice, a Mysterious Stranger appearance in the Fallout show could also add an element of intrigue. Where Fallout 4 took the first steps toward investigating the Mysterious Stranger—with private detective Nick Valentine building a file on the character—the Fallout TV show could go one step further, giving players further insight into the Mysterious Stranger’s lore and place in the Fallout universe. Though it would be a risk to expand on the lore of one of the franchise’s most mysterious and beloved characters, the Fallout show has already shown that it is both willing to take risks and careful when dealing with lore elements. This is one more game element worth aiming for.
