The Martin Riggs Lethal Weapon TV show character is one of the most recognisable figures in modern television action drama: a brilliant, reckless detective whose grief and humour drive the series from its first episode. This guide explains the Martin Riggs Lethal Weapon TV show story in full, covering who Riggs is, how the series reimagined the famous film character for television, the major story arcs across the show’s run, and how the role changed during the series, all framed through the character’s career on screen.
Lethal Weapon began as a film series in the late 1980s, pairing the volatile Martin Riggs with the steady, family-minded Roger Murtaugh. The television version, which aired on Fox from 2016 to 2019, kept that central partnership and rebuilt it for a weekly series. The Martin Riggs Lethal Weapon TV show version is younger than the film version and is placed at the start of a new chapter in Los Angeles, where a transfer from Texas brings him into Murtaugh’s orbit and into a series of cases that test both men.
Martin Riggs Lethal Weapon TV Show Character Overview
In the Martin Riggs Lethal Weapon TV show, Riggs is introduced as a former Navy SEAL and a detective with the Los Angeles Police Department, transferred after a personal tragedy in Texas. He is exceptionally skilled in the field, fearless to the point of recklessness, and quick with a joke even in dangerous situations. That humour is not just comic relief; it is part of how the character copes, and the show returns to it again and again as a clue to what he is carrying underneath the jokes.
Riggs is paired with Roger Murtaugh, a veteran detective who values procedure, family, and going home safely at the end of the day. The partnership works because the two men are opposites who need each other. Murtaugh steadies Riggs, and Riggs pushes Murtaugh out of caution and back into the kind of police work that made him a detective in the first place. Their banter, arguments, and growing loyalty form the emotional spine of the series, just as they did in the films, and many of the show’s best scenes are simply the two of them talking in a car between cases.
What Makes Riggs Different From Other TV Detectives
Many television detectives are defined by a single trait, such as brilliance or toughness. Riggs is defined by a contradiction: he is both the most capable person in the room and the least concerned about his own safety. That contradiction creates tension in almost every episode, because his colleagues cannot tell whether his next risk is a brilliant instinct or a self-destructive impulse. The show uses that uncertainty well, letting other characters challenge him, worry about him, and occasionally save him from himself.
Riggs is also unusually open about his emotions for an action hero. He talks about loss, he seeks help at different points in the series, and his relationships with colleagues, friends, and family members are given real screen time. That openness is what separates the television Riggs from a simple action figure. Viewers are invited to care about him as a person, not just to admire his skill in a chase or a fight.
Martin Riggs Lethal Weapon TV Show Story Arcs
The Martin Riggs Lethal Weapon TV show story unfolds across three seasons, with each season balancing weekly cases against a longer personal arc. In the first season, the focus is on Riggs arriving in Los Angeles, forming his partnership with Murtaugh, and confronting the loss that brought him west. The weekly cases introduce the show’s rhythm: a crime, an investigation that goes sideways, a chase or confrontation, and a quieter scene in which the partnership deepens.
The second season expands Riggs’s world. New colleagues, new relationships, and new threats from his past raise the stakes, and the show explores whether Riggs can build a stable life in Los Angeles or whether his past will keep pulling him back. His bond with Murtaugh’s family grows stronger in this season, and the series leans into the idea that family, both given and chosen, is the force that might finally anchor him. The action remains large-scale, but the emotional story becomes the reason to keep watching.
The third season brings the biggest change in the Martin Riggs Lethal Weapon TV show run. Clayne Crawford, who played Riggs in the first two seasons, left the series, and the show introduced a new lead character played by Seann William Scott. Scott did not play Riggs; he played a different character, Wesley Cole, a former CIA operative who becomes Murtaugh’s new partner. The series addressed Riggs’s departure within its story, and the focus shifted to how Murtaugh adapts to a new partnership while honouring what came before.
The Partnership With Murtaugh
Across all three seasons, the Murtaugh partnership is the constant. In the Riggs seasons, Murtaugh is the voice of caution and experience, constantly negotiating between protecting his partner and letting him do the job only he can do. Their relationship moves from suspicion to trust to genuine friendship, and the show marks that progress in small moments: shared meals, family gatherings, and the unspoken understanding that each man will come back for the other.
That partnership is why the show survived a change of lead. Audiences had invested in Murtaugh as much as in Riggs, and the series built its third season around Murtaugh’s grief, adjustment, and new beginning. Wesley Cole is written as a different kind of partner, with his own history and style, rather than as a copy of Riggs, which lets the show honour the original pairing without pretending nothing changed.
Key Themes in the Riggs Story
Three themes run through the Martin Riggs Lethal Weapon TV show arc. The first is grief and recovery: Riggs’s story is, at its core, about a man learning whether he can live with loss and build something new. The second is loyalty: the show repeatedly asks what partners owe each other, and answers that loyalty means honesty, even when honesty is uncomfortable. The third is the cost of the job: the series shows, sometimes starkly, what high-risk police work does to the people who do it and the families around them.
These themes give the action its weight. A chase is exciting on its own, but a chase in which Riggs risks himself to protect someone he has come to care about carries a different charge. The show’s writers understood that balance, and the best episodes pair a strong case with a personal turning point for Riggs or Murtaugh, so that the action and the emotion reinforce each other.

Martin Riggs Lethal Weapon TV Show Legacy
The Martin Riggs Lethal Weapon TV show legacy rests on how successfully it translated a film icon to weekly television. Film Riggs, played by Mel Gibson, is a cultural touchstone, and any television version faced an obvious comparison. The series met that challenge by keeping the spirit of the character, the reckless skill, the humour, and the heart, while giving him room to grow across dozens of episodes rather than a two-hour film. That longer format let viewers see Riggs at his best, at his worst, and in the quiet moments between cases, which a film rarely has time to show.
Clayne Crawford’s performance is central to that legacy in the first two seasons. His Riggs is charming, volatile, and vulnerable in turn, and his chemistry with Damon Wayans as Murtaugh carries the series through its strongest stretches. The show’s later change of lead is part of its story too, and it is often discussed by fans as a turning point: a reminder of how much a series can depend on a single partnership, and how difficult it is to replace one half of it.
Why Fans Still Talk About Riggs
Fans still talk about the Martin Riggs Lethal Weapon TV show character because the pairing of action and emotion still works. Rewatching the Riggs seasons offers both the pleasures of a well-made procedural, with strong cases and inventive action, and the satisfactions of a character drama, with a hero who is allowed to struggle and change. That combination is rarer than it looks, and it is why clips, episode discussions, and cast retrospectives continue to circulate years after the finale.
The character also endures because he connects the television series to a larger tradition. Lethal Weapon helped define the buddy-cop genre, and Riggs is one half of its defining partnership. The television version kept that tradition alive for a new audience, introducing younger viewers to a dynamic that shaped decades of action films and shows. Whether a viewer starts with the films or the series, Riggs is the entry point to that tradition.
