Reacher’s 13 Best Supporting Characters, Ranked

Jack Reacher is a truly unique character in the action thriller genre, and the Prime Video series Reacher has brought him to even more viewers with its great adaptation of Lee Child’s novels. While the show stays mostly true to the books, two key changes actually make the story even better.

The show Reacher tackled its biggest hurdle by letting the main character speak more than he does in the novels. While some fans weren’t thrilled with this change, it was important because the story relies heavily on Reacher’s internal thoughts. Giving him more lines also strengthened his connections with the supporting characters, which is crucial for believable on-screen interactions. Another key improvement was expanding the roles of those supporting characters, turning many into memorable heroes or compelling villains.

13. Richard Beck

Played By Johnny Berchtold

A beloved character meets their end in a single episode of season 3, creating a moment fans had been anticipating. Unlike many of the secondary characters in Reacher, Richard isn’t skilled in fighting or planning. Surprisingly, despite being somewhat naive and needing help, Richard quickly became a favorite among viewers.

Richard, the son of the troubled Zachary Beck, is a gifted and kind person who loves ice cream. He understands he’s trapped in a difficult situation and longs to be free. While he doesn’t have many dramatic moments, it’s obvious he has valuable skills that would thrive elsewhere, making his season finale a hopeful one, similar to the outcome for Reacher.

12. Shane Langston

Played By Robert Patrick

Robert Patrick has built a career playing strong, intimidating characters, and his role as Shane Langston in season two of Reacher is no exception. Langston serves as a compelling villain, contrasting the Special Investigators by selling the “Little Wing” missile to a dangerous arms dealer. Although the season’s overall storyline wasn’t as strong as previous ones, Langston was a well-developed character whose impact was unfortunately diminished by a weak plot point.

Effective villains usually take action before explaining themselves, but Langston’s long-winded speeches ironically gave Reacher and his team crucial time to react. This often made their victories seem like fortunate accidents. However, Langston’s dramatic method of eliminating opponents – having his followers throw them from a helicopter – perfectly set the stage for their ultimate, airborne confrontation.

11. “A.M.”

Played By Ferdinand Kingsley

A.M., a character with multiple identities, is captivating, cruel, and deeply unsettling, sometimes all at once. His scheme involving a cosmetic surgeon and his team is a highlight of Reacher season 2. Unlike villains like Tuco from Breaking Bad or Moriarty from Sherlock, who are thrilling because of their wild actions, A.M. is just as unpredictable but maintains a chilling calmness.

Season 2 of Reacher features multiple villains, but A.M. is particularly interesting because he shares some key similarities with Reacher himself. Both men are wanderers, seemingly without a permanent home or strong connections. While Reacher holds onto his identity despite owning little, A.M. is driven solely by financial gain and operates almost like a phantom.

10. Zachary Beck

Played By Anthony Michael Hall

Though Zachary Beck initially seemed like a typical villain in season 3 of Reacher, Anthony Michael Hall brought depth to the role, making him a troubled and relatable character. The season quickly showed that Beck and his son were actually hostages being manipulated by the true antagonist, Quinn.

Lee Child described the outcome for his character, Reacher, as “a sad twist,” especially because the complex relationship between Beck and his son was central to the story. The reasons behind Beck’s distant behavior toward Richard were gradually revealed, making their connection as interesting as any other relationship in the series – even those involving Reacher himself. While Beck’s fate wasn’t entirely unexpected, Alan Ritchson’s performance ensured it still had a strong emotional impact.

9. KJ Kliner

Played By Chris Webster

If you weren’t familiar with the Jack Reacher novels, the character of KJ initially seemed like a privileged and entitled young man using his wealth to get what he wants. His unpleasant personality serves a purpose, though: it makes both the audience and Reacher underestimate him.

The three seasons of Reacher
Season	Year	Rotten Tomatoes critics’ rating	Rotten Tomatoes audience rating
1	2022	92%	91%
2	2023	98%	77%
3	2025	98%	73%

The first season of Reacher ended with a truly shocking twist, and it cleverly paved the way for future seasons filled with unexpected turns. While later villains have also surprised viewers, none have been quite as unsettling as the reveal that KJ was responsible for the deaths of both his father and Reacher’s brother. Given how action-packed Reacher is, it’s hard to create a villain audiences will remember unless they’re physically imposing or a credible, distant threat. However, KJ stood out as a unique character even before the shocking truth about his past was revealed.

8. Guillermo Villanueva

Played By Roberto Montesinos

Each season of Reacher features a new setting, so viewers learn not to get too invested in supporting characters. However, unlike some action shows that prioritize action over character development, Reacher consistently builds compelling characters. The series continues to improve, and season three boasts some of its best, like Guillermo Villanueva, who surprisingly made it through the season.

Guillermo initially seems like an easy character to eliminate – he’s tired and always snacking. But he quickly proves invaluable, offering practical advice and surprisingly outsmarting tougher opponents. His caring side, especially towards the upset Richard, and his heartwarming return home to his wife give him a satisfying conclusion, a far cry from the unremarkable retirement he expects as a law enforcement officer.

7. Xavier Quinn

Played By Brian Tee

Reacher is determined to get revenge on Xavier Quinn, who brutally tortured and killed someone Reacher cared about, Dominique. While some plot points, like Reacher surviving being shot and then losing his memory, don’t quite add up, the show is worth watching because the actor playing Quinn is fantastic at portraying a truly terrifying villain. Quinn stands out from other antagonists on the show – who are usually motivated by greed, cunning, or power – because he clearly enjoys inflicting pain.

Similar to Beck, Quinn is shown to be working under someone he fears, but his personality and past actions don’t make him seem any less threatening. He constantly keeps everyone guessing about whether he recognizes Reacher, and although his death was expected from the book, he had the potential to be a truly compelling villain.

6. David O’Donnell

Played By Shaun Sipos

Many viewers loved Reacher’s old coworker and are hoping he appears in season 4. O’Donnell was both humorous and complex – not just a funny sidekick, but someone who could have easily been a hidden enemy. He stood out because, unlike most people Reacher encounters, he genuinely understood him while also keeping him grounded with perfectly timed remarks.

Despite delivering many of the show’s funniest moments, O’Donnell remains a crucial and capable member of the Special Investigators. Even when Reacher’s actions became expected, O’Donnell’s storyline kept viewers guessing – his devotion to his family suggested he might not make it home, and his hidden behavior implied he could be working against Reacher. Now that his loyalty has been established and he’s become a fan favorite, O’Donnell could reappear in future seasons, just like Finlay and Neagley.

5. Gaitano Russo

Played By Domenick Lombardozzi

Like many of Reacher’s eventual allies, Russo initially seems like an enemy. He shares a tough, intimidating presence with characters like Tony Soprano and Vic Mackey from The Shield, and could easily have been portrayed as a corrupt officer. However, Russo’s strong sense of right and wrong, and his determination to fight the true villains, won Reacher’s respect. Unfortunately, this ultimately led to a heartbreaking end for his character.

As a huge Jack Reacher fan, I was genuinely stunned when Russo stepped in front of that bullet meant for the kid. It was a major departure from the books, but honestly, it created some of the most powerful moments of the season. It was the first time the show really hit me emotionally, and it was heartbreaking to see Neagley, who never shows physical affection, break her rule to comfort Reacher. It really underscored the impact of Russo’s sacrifice.

4. Paulie

Played By Olivier Richters

Jack Reacher is known for his imposing size, so when another character appeared who made him look small, it immediately hinted at a classic underdog fight. The showdown, which had been building throughout the third season, lived up to expectations with intense and over-the-top action. Paulie was the stronger of the two, but his underestimation of Reacher led to a violent conclusion involving a machine gun that had been prominently featured throughout the series.

Olivier Richters, a 7’2″ professional bodybuilder and actor nicknamed “The Dutch Giant,” plays Paulie. He’s nearly a foot taller than Alan Ritchson, who is 6’3″, and his impressive size and strength immediately grab your attention. But Paulie isn’t just intimidating – Richters also gets to showcase some comedic timing, adding another layer to the character beyond his physical presence.
