In her teenage years, she hangs out with the other rich, popular girls at her high school. One such friend was the queen bee of her class; Yasmine, who had been chatting on the phone when her SUV collided with a Pontiac Firebird owned by Johnny Lawrence. A furious Johnny banged on the window of the SUV, demanding Yasmine furnish her driver's license and name of her insurance agency to him. Samantha, who was in the backseat, did not know how to react, and saw Johnny as a potential crook. Yasmine, who did not know protocol for handling a car accident, drove off. When Johnny's car was towed to LaRusso Auto Group, he recognized Daniel's daughter as one of the girls he shouted at.

Samantha resumes her training

Her relationship with her father is strained by his meddling in her potential romance with a fellow student named Kyler, but they reconcile after Samantha sees Kyler bully Miguel's friend group and subsequently ends their relationship. When Kyler begins spreading lies about her, Samantha is briefly friendless. Miguel eventually defends her and defeats Kyler's clique in a lunch room fight, after which he and Samantha begin dating. Samantha really likes Miguel but hides their relationship from her parents because her father disapproves of Cobra Kai. A series of assumptions and misunderstandings lead Miguel to believe that Samantha is ashamed of him and involved with Robby Keene. Between that and Robby's resentment over his father's Johnny Lawrence karate tutelage of Miguel, antagonism sparks between the two boys when they meet at a beach party.

However, after Robby kicks Miguel off the railing, Miguel is badly injured, Sam screams "Robby what did you do?"

Sam is rushed to the hospital. When Daniel and her mom Amanda LaRusso visit her in the hospital, they are appalled at Sam's condition and vow to get Tory expelled from school. Sam starts crying and blaming herself for what happened, saying she is not concerned about that; all she wants is for Miguel to get better.

Sam has a panic attack

Things gradually worsen between the dojos as the Cobra Kai's seek revenge for Miguel's accident. Sam refuses to be bullied and decides to show the Cobra Kai students they aren't doormats. The Miyagi-Do students take a stand during what escalates into an intense soccer game. To retaliate, the Cobra Kai students head to Golf N' Stuff Arcade and attack Chris at work, leading the Miyagi-Do students to help their friend and confront Cobra Kai. The confrontation leads to a fight in the laser tag section of the arcade. When Tory Nichols arrives and calls Sam's name, she suffers a panic attack during the fight as her body shuts down and stops her from defending Chris, who gets beaten up by Doug and Mitch or the rest of the Miyagi-Do students. She is forced to witness Hawk break Demetri's arm while Tory taunts Sam to show herself before vowing its not over. Sam blames herself for Demetri having his arm broken and breaks down in her mother's arms at the hospital while waiting with the Miyagi-Do's for Demetri's arm checks.

Sam decides to continue her training

Left with more trauma, Sam decides to quit karate for good and distances herself from everyone. Upon returning from Okinawa, Daniel learns the severity of Sam's trauma. He reconnects with her over a father-daughter fishing trip, though she isn't keen on the idea. She makes it known that she doesn't want to learn karate anymore and just wants her friends to be safe.

He sympathizes with her and assures her that he wants what is best for her. She decides to continue her training and learns how to fight with a bo staff.

When Miguel returns to school now fully recovered, Sam reconnects with him as he slowly realizes how bad things became after his accident.

Sam and Miguel during the LaRusso house fight

The brawl leads to a battle between Tory and Sam, in which Sam initially attempts to run away from as she still hasn't recovered emotionally from their last encounters. As Tory pummels Sam and begins to attack her with nunchaku, Sam remembers what her father said - only she can help herself when she's down. She regains her strength and is able to disarm Tory with her bo staff, until they are interrupted by a bloodied Miguel, Hawk, who has now joined the side of Eagle Fang Karate, and Demetri. Hawk warns Tory that the fight is over. She eerily tells Sam that the war between them will never end. Daniel learns of the attack and confronts Kreese, and the three rivaling sensei's - Daniel, Johnny, and Kreese, agree to a tournament to determine if Kreese will leave the valley or if Miyagi-Do and Eagle Fang will.

While he works with Johnny, she hopes she can convince Robby to return, unbeknownst to Miguel. Robby, however, has no interest in giving Johnny or Daniel a second chance. She admits she didn't stop caring about him, but he knows she didn't stop caring about Miguel either. Robby points out that she made her choice, and has to live with that. She just wants him to come back as it would help unite everyone. He is pleased to be the first person to tell her she isn't getting what she wants. She accepts his choice, but reminds him that he made it, not her.

While she is training with Johnny, they argue over jumping from building to building and tells him that Daniel wouldn't allow her to jump buildings. They talk about their previous encounters including the hit-and-run incident and Daniel rescuing her by breaking Johnny's door. She then rebuttals and explains to him about his current lifestyle but Johnny explains that if he listens to his parents, he'd have a decent job. Johnny then fails Miyagi-Do for not jumping but after her father texts him not to do things he wouldn't do, Sam then takes the risk and finally jumps to the next building, impressing Johnny and her classmates.

Sam and her mother see Tory working at the party place

Sam and her mother are at a party place for one of their worker's kids. Unbeknownst to her, Tory also works at the party place. She enjoys the performance but Tory is upset that she was watching. When Tory was telling a story to the kids, Sam interrupts the story by comparing it to their recent experiences, in order to aggravate Tory. Now fed up, she tells the kids to throw glitter at Sam. When Miguel arrives, Sam intentionally kisses him in front of Tory to get back at her, which aggravates the latter who storms out.

During school, she and Miguel tell Hawk and Demetri that both Daniel and Johnny are having a rematch at Miyagi-Do. When she gets home, she and her father argue about Johnny's teachings.

Sam and Miguel then fight Tory and Robby, but Sam, Tory and Miguel are pushed into the pool by Robby.

Sam bows to her two senseis during the tournament

On the day of the All-Valley Tournament, Sam is showing her skills using sai during the skills demonstration.

She wins her next matches, setting up the final match between her and Tory. Miguel congratulates her for reaching the final round and before she goes back to the arena, she and Miguel reconcile. During the final round, she incorporates Miyagi-Do teachings and Eagle Fang's teachings. At one point during the fight, Sam hits Tory who then stumbles out of bounds, but the referee does not give Sam point and incorrectly states that Tory was already out of bounds. When tied 2-2, Tory hits Sam in the eye, but does not even get a penalty. Unfortunately, Tory beats her and wins the girls division, also leading Cobra Kai to becoming grand champion but after Tory is declared the third point, she asks if Sam is physically okay. While Cobra Kai celebrates their victory, Sam then goes back to Daniel, telling him that they still didn't win despite doing the right thing. But Daniel gives Sam advice that it wasn't her fault. The LaRusso's then come home disappointed for their loss. Unbeknownst to Sam, Kreese's friend and one of the original owners of Cobra Kai, Terry Silver, who is co-teaching with Kreese at Cobra Kai, had apparently paid the referee to help Tory and Cobra Kai win, ultimately implying that the referee was intentionally biased towards Tory during the finals, as well as that Sam would have been the winner had he been fair.


"Maybe my right way is different than your. Don't I get a choice?"
―Samantha LaRusso to Daniel LaRusso[src]

Sam is a nice, polite and smart person. Despite hanging out with the popular crowd who are mean and nasty, Sam does not behave like them, showing she has her morals, and is able to maintain her true self. However joining the popular crowd does end their friendship with Aisha Robinson, though they are at the very least on speaking terms. After noticing her boyfriend Kyler bullying Miguel, Demetri and Eli she dumps Kyler, showing she is against bullying. After dumping Kyler, he ruins her reputation with her friends by making up lies about her, which causes her to lose her friends. Fortunately she develops a relationship with Miguel and even becomes friendly with Robby. She forms a friendship with Robby. Unfortunately a misunderstanding makes Miguel angry and accidentally hit Sam, causing her to dump him because she was holding Robby's hand. At the All Valley Tournament she seemingly makes up with Aisha after apologizing to her. She ultimately leaves the tournament after Miguel angrily tells her that he will hurt Robby, showing that she cares for Robby and fears Miguel then she knows that she made a mistake for starting the extended rivalry between.

At first she is heartbroken over her relationship with Miguel ending. However, after joining Miyagi-Do Karate where she spends time training and hanging out with Robby whom she develops feelings for, she seems to forget about Miguel. She tries to fix her friendship with Aisha, but the latter, who is angry at Daniel for insulting Cobra Kai in order to promote Miyagi-Do, takes her anger out on her, as well as has already befriended a new Cobra Kai student Tory. Believing that Tory has stolen her mom's wallet, she accuses her, but the latter denies without proofs. The two then get into a brief scuffle. Following this the two are rivals, though it's mostly on Tory's part as she frequently bullies and insults Sam. She and Robby eventually become a couple. However, she still has feelings for Miguel, and on the night before the first day of school a drunken Sam and Miguel share a kiss. Despite Miguel regretting the kiss as they are both in relationships, Tory, who is dating Miguel sees them kiss, but they are unaware that she caught them. It is the kiss that leads to the school brawl the following day.

After Miguel is rendered unconscious during the school brawl as a result of Robby kicking him off the railing Sam screams "Robby what did you do"? At the hospital Sam tearfully says she hopes Miguel's ok, showing she feels guilty about what happened. Sam even blames herself for the school fight. Her fight with Tory leaves Sam traumatized to the point that she freezes and has a look of fear on her face when Tory calls out her name, leading to her quitting karate. However, after getting encouragement from Daniel, she re-joins karate and eventually gets over her fear during her fight with Tory, allowing her to gain the upper hand over the latter. After Miguel is released from the hospital, the two rekindle their friendship. However, her relationship with Robby ends when he attacks Miguel for believing they had a thing going on. Shortly after the break up, she and Miguel rekindle their relationship.

In the fallout of the house fight and during the merge between the two dojos, Sam began to grow tired of the ideas her father placed on her as she was visibly uncomfortable when Daniel called her LaRusso 2.0 as well as when he jokes about her taking over the dealership in the future. While she was hesitant at first to train under sensei Johnny Lawrence due to his extreme methods, she started to follow Johnny's ideas after realizing that she didn't have to follow the same path her father followed. Unfortunately, Sam's Eagle Fang training also made her acquire a more impulsive nature about her problems, choosing to immediately attack anyone that threatened her instead of defusing the situation. Her new behavior was directly focused on Tory, whom already tried to kill her twice, leaving Sam to start instigating her at every chance she got, claiming that she was tired of the attacks she previously took from Tory. During the tournament Sam initially followed his father styles and ideas, but when the Miyagi-Do teachings proved to be useless as Cobra Kai had already learned them, she resorted to using the style that Johnny taught her by saying that she is the one that gets to decide which style should use. Sam eventually gets closure when her father finally accepts his ways and motivates her to use everything she learned to fight her own way. Despite this, she ends up losing the tournament to Tory which leaves her feeling very guilty.

Fighting Style

"You don't have to worry about me, Dad. I can handle myself. I'm a LaRusso."
―Samantha LaRusso to Daniel LaRusso[src]

Samantha taking down Miguel

Samantha trained in martial arts with her father as a child, and it is shown in season 1 that she has retained that knowledge when she fights off Kyler's advances and performs a takedown on Miguel.

After resuming her training in season 2, Sam shows that she's a quick, acrobatic, and elusive fighter with sound technique. Thanks to their tandem training she fights extremely well alongside Robby due to all the training the two shared, holding off several Cobra Kai students during the brawl at the mall with the wheel technique she and Robby practiced. During their training with Shochu-Geiko exercise, Sam was the only one that managed to attack Robby with success, she also managed to defend Robby's attacks during the Kangeiko variant by anticipating his strikes in the extreme cold. Sam had more trouble in her one on one fight with Tory during the school brawl, as she struggled with Tory's aggressive, however, Sam did barely managed to defeat her after a protracted fight.

During the arcade fight on Season 3, Sam is shown to easily defeat most of Cobra Kai's students, which include Mikey, Doug and Hawk, but she's unfortunately unable to keep fighting after Tory shows up as she started to froze do to her trauma from the school fight. Daniel later trains Sam with the bo staff in order to heal her trauma. After Tory broke into the LaRusso household with a bunch of Cobra Kai students to fight, Sam managed to keep up with most of her rivals but her PTSD briefly stopped her from taking on Tory once again. Fortunately, Sam quickly overcome her trauma and used a bo staff, which gives her a vital edge when Tory attacked her with nunchucks, defeating her once again.

Sam using both Miyagi-Do and Eagle Fang styles

During Daniel's and Johnny's brief alliance, Sam got to train under sensei Johnny Lawrence, who taught her a more offensive style of karate that diverged from the Miyagi-Do teaching she knew. Sam's Eagle Fang training made her add more aggressive moves to her repertoire, like the flying tornado kick, which she later used in the All Valley Tournament. During the fight in the prom after party, Sam strikes first against Tory and gains the upper hand, until Miguel stops her. When they fight again shortly after, Tory has the upper hand at first but then they appear to be even until Robby pushes Miguel and Sam into the pool. During the new skills competition at the All Valley Tournament, Sam shows her proficiency with Sai. In the quarterfinals of the all valley tournament, while initially losing to Piper, she regains her bearings and wins by using the Eagle Fang technique. In the finals, she combines both the Miyagi Do and Eagle Fang styles to put up a strong fight against Tory. While Sam does lose after a tough and close fight, that may be attributed to Terry Silver bribing the referee.

Due to her years of experience since childhood and her decision to combine styles from two different dojos, Sam is currently the strongest student at Miyagi-Do and one of the strongest among Miyagi-Do and Eagle Fang.

In the hospital, Amanda consoles Sam in the hospital when Sam was crying about Cobra Kai breaking Demetri's arm and her being unable to save Demetri.

Despite being virtually strangers, Robby pitied Sam when she's grounded and unable to attend her friends party. He faked a sprained ankle so they could attend the party. When Miguel saw them together, he became jealous and picked a fight that ultimately ended his relationship with Sam. When Daniel learned that Robby lived alone, he invited the teen to stay with the family. Robby and Sam were paired together inside Miyagi-Do, which allowed them to gradually grow closer. They worked seamlessly together in karate, being the perfect partners for one another. They acted as extensions of one another in a fight.

In the arcade, while Cobra Kai and Miyagi Do are fighting each other, Sam is left frozen when Tory says her name and calls out "where are you bitch?!", remembering their last fight at the school, Sam is left having a panic attack and hides from Tory when she has PTSD visions from the school fight which makes her unable to fight back and is forced to witness Hawk and Tory break Demetri's arm. In her nightmare, after Sam finishes her warm-up, she goes to the back door of Miyagi-Do, until she sees Tory appear out of nowhere. Tory kicks her in the face, and Sam has flashbacks of the school fight. She grabs Sam's hair and places her face in the pond to drown her in the nightmare. After being drowned in the pond, she realizes that it was all a dream. Back at the LaRusso's, Eagle Fang and Miyagi-Do are thinking of working together and to join forces to fight back against Cobra Kai in a bigger team until Cobra Kai breaks in the LaRusso's home. Tory beats up a Miyagi-Do student and she sees Sam and chases after her into the Miyagi home Dojo. Tory finally corners Sam in the LaRusso home dojo, however Sam is too frightened at first to fight against Tory. Sam remembers a quote from her father telling her she can get up when she is down. Tory says that she will need to make her own fun. Tory grabs a pair of nunchaku and attempts to attack Sam only to smash a picture of Mr. Miyagi. Sam then gets up and grabs a boa staff, and overcomes her fear. Sam and Tory have a fight and Sam lands a few hits on Tory with the boa staff. Sam eventually disarms and corners Tory, the fight is interrupted when the redeemed Hawk, Miguel and Demetri arrive and break up the fight. Hawk tells Tory that the fight is over, Tory refuses to believe the fight is over and she approaches Hawk and Miguel where she calls the two 'traitors' and threatens Hawk to watch his back but Demetri defends them and says they have friends watching it for them. Tory then leaves the home dojo.

In season 4, Tory and Sam's rivalry continues, though it has been dealt with by Amanda who threatens Tory to face a worst punishment if she comes near Sam again. When Tory is telling kids a story during a party for a worker's child, Sam intentionally mocks her by bringing up stuff that Tory did to her in the past, while also laughing at her singing, much to Tory's annoyance. Tory gets her revenge by convincing the kids to throw glitter at her, but Sam then instigates her again by intentionally kissing Miguel while Tory is looking at them, which leads to an angry Tory storming out. She and Tory cross paths at the high school prom, where she watches Robby dance with her. At Stingray's afterparty, Sam insults Tory but after the latter retaliates, Sam attacks her resulting in a fight at the party. Shortly after, Sam and Miguel fight Robby and Tory, but both lose when Robby pushes them into Stingray's pool. The two then face off in the final match where Tory wins the girls division, causing Cobra Kai to become grand champion. Despite losing to Tory in the tournament, her rival still shows some respect, as shown when she tells Sam if she's all right. This is most likely because Amanda told Tory to end her conflict with Sam during the tournament, as well as giving her advice to fight fairly regardless.

Aisha Robinson

Aisha is Sam's former best friend whom she has a strained relationship with. They became friends before Cobra Kai, but at some point before the series, Samantha became friends with the popular crowd, who often bullied Aisha. While Sam's actions strained their friendship, they were still on friendly and speaking terms.

During the early parts of season 1, Aisha and Sam are on speaking and good terms, despite Sam's association with the rude popular crowd. Despite disapproving the crowd, most notably Yasmine bullying Aisha, Sam never stands up for Aisha, possibly out of peer pressure. Halfway into the season when Sam loses her friends and becomes an outcast, Aisha shows no sympathy and is cold to her, possibly because she feels that Samantha is getting what she deserves. However, she seemingly forgives Samantha after she apologizes to her and tells her her revenge against Yasmine was great. The two then laugh about Aisha's revenge against Yasmine. Aisha encourages her to get back into karate.

Sam wants to rekindle her friendship with Aisha, but the latter still holds somewhat of a grudge against her. When Sam accuses Tory of stealing her mom's wallet, the two get into a brief fight. Aisha is dismayed at Sam for making an accusation without proof. During a party at Moon's house, Sam becomes even more irritated at Aisha because Hawk and a group of Cobra Kai students vandalized the Miyagi-Do, even though Aisha told her she had nothing to do with the incident. During her talk with Aisha, Sam tells Aisha that her victory in the drinking battle between her and Tory should be considered as payback, showing that Sam still will not heal her strained relationship with Aisha. She tells Sam that Miguel returned Mr. Miyagi's Medal of Honor which shocks her. When Sam appears to be dizzy, Aisha shows concern for her, showing she still cares for her. The following morning she messages Sam, asking her if she is alright, further indicating that she still cares about her. Aisha's decided to transfer her to a private school after the West Valley fight.

Sam visits Aisha ever since she moved and they talk about their recent experiences. In the end, Aisha tells Sam that she will be her original best friend.

Johnny Lawrence

Johnny was Sam's former enemy and now a sensei of her dojo. When Sam and her two friends crash Johnny's old Pontiac Firebird, Johnny is angry at her and her friends. Johnny holds some sort of anger against Sam for the hit and run incident and also the fact that her friends are bullying Miguel constantly. He even reminds Daniel about the type of friends Sam makes back in Season 1. In Season 2 and 3 they don't have interactions, but by the end of season 3, Johnny becomes the co sensei of the merged Eagle Fang Karate and Miyagi-Do, alongside Daniel, making Sam his student. Despite the merge not going well, she incorporates Johnny's teachings alongside Miyagi-Do in order for her to survive the tournament.
