Biography

Pre-Cobra Kai

Samantha is the daughter of Daniel and Amanda LaRusso and the older sister of Anthony. At the age of 8, Sam was taught karate by her father, and was close to Mr. Miyagi. He described their relationship as the first time he felt like a Grandfather. As Sam got older, she lost interest in karate and quit. However, she retained her knowledge and skill.

Cobra Kai

Season 1

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.

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. Samantha is upset with Miguel's behavior and breaks up with him. After a second confrontation with Miguel at the All-Valley Tournament, Samantha returns home and resumes her own karate training.

Season 2

Sam, upset over her breakup with Miguel blocks him on social media. At first she decides not to join Daniel's Miyagi-Do Karate training because she does not want to fight her Cobra Kai friends, but soon changes her mind.

She tries to patch things up with Aisha but the latter is upset with her when Daniel insults Cobra Kai in his commercial. She develops a dislike to new Cobra Kai student Tory. When her mom's wallet is missing during a pool party she immediately accuses Tory who angrily denies having it. She then grabs Tory's hand but Tory knocks her down. This incident starts their rivalry.

After struggling to get more students at Miyagi Do for several days Sam's Daniel's and Robby's luck changes when Cobra Kai's ruthless teaching cause several students to join Miyagi-Do. Overtime she and Robby develop feelings for each other. While Robby at first thinks it is a bad idea for them to date, he soon eventually changes his mind and the two start dating but don't tell Daniel.

When Sam and Robby go to a skating party together they run into Miguel and Tory who are a couple. While she and Miguel wait in line to get more skates Sam asks him why he is dating Tory which offends him and the two have a brief argument. When Tory intentionally knocks her down, Sam, fed up with her behavior, knocks her down, but this angers Miguel and causes both she and Robby to get kicked out despite Miguel and the possible manager being unaware that Tory started it.

When Sam and Robby go to Moon's house for a party she gets revenge on Tory by beating her in a drinking contest, but she gets too drunk which makes her woozy. After finding out from Aisha that Miguel returned Miyagi's medal of honor which Hawk stole a while ago she goes outside to get some air. When Miguel checks up on her she thanks him for returning the badge and the two share a kiss but immediately regret it. However, they are unaware that Tory saw them kiss.

After the cops arrive everyone leaves the party and Sam tells Robby not to take her home because she does not want her parents to see her drunk. So, Robby takes her to Johnny's house and the two spend the night there. The following morning however Daniel arrives at Johnny's door, and both he and Johnny have a brief fight until Sam and Robby stop them Daniel then angrily takes her home.

While Sam is in class on the first day of school she is threatened by Tory over the intercom for kissing Miguel. When She and Tory meet in the hallway, Tory viciously attacks her. Robby attempts to stop the fight, but Miguel, unaware of Robby's intention, attacks Robby. Sam and Tory resume the fight and a huge brawl between Miyagi-Do and Cobra Kai soon breaks out. Sam tries to get Tory to stop fighting but the latter won't listen. Despite struggling for a while, Sam is eventually able to get the upper hand. However, Tory then attacks Sam with her spiked bracelet and manages to injure Sam's wrist with it. Tory is about to stab her with the bracelet but Sam kicks Tory off her and then kicks her down the stairs, winning the fight. However, after Robby kicks Miguel off the railing, resulting in Miguel being 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. When Daniel returns to the hospital and notices Sam isn't in the room, Amanda tells him the doctor prescribed X-rays for her, believing her injuries more serious than originally thought; possibly a broken rib.

Season 3

Sam is left traumatized by the events of the school fight. Her arm now dons three scars from the impact of Tory Nichols' brass knuckles. Sam's consequence for fighting is a two-week suspension from school. Her parents attempt to protest the suspension but fail to change the principal's mind. She struggles to regain a sense of normalcy after the event but is determined to help Miguel with his surgery. In the meantime, she writes emails to Robby who is serving time in a juvenile detention center for his role in Miguel's accident. As she waits for his replies, Sam organizes a car washing fundraiser in the hopes of contributing to Diaz's medical fund. When the students from Cobra Kai Dojo attack Nathaniel and steal the fundraising money to donate in the name of Cobra Kai, Sam steps up to train the Miyagi-Do Karate students properly and becomes their leader while Daniel is away at Okinawa, Japan to save the dealership which is at hands of collapsing by Tom Cole. Her escapades are cut short by her mother, who is upset over Sam's returns to karate. Sam brushes her mother's concerns off, claiming that she doesn't know what is going on with the rivaling dojos.

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 attack Chris at his work, leading the Miyagi-Do students to confront Cobra Kai. The confrontation leads to a fight in an abandoned mall shop. Sam suffers a panic attack during the fight as her body shuts down and stops her from defending Demetri 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. 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.

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. The trip helps her remember why she loves karate, and Daniel reminds her that only she can help herself when she's down and no one else. 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. He refuses to train under Kreese or be friends with Cobra Kai students after everything they did to Sam and the others. Her and Miguel deliver a speech together to save the All Valley Karate Tournament when the council deems it "harmful to the community." They convince the city council to hold the tournament, which brings Miguel and Sam closer. They share a moment in the Miyagi-Do dojo that is unfortunately witnessed by a now released Robby. He believes Sam and Miguel were dating the entire time he was in juvie. He also thinks they were having an affair before Miguel's accident. Robby attempts to fight with Miguel until Sam pushes him away. The pair end their relationship, and Robby leaves. In the days that follow, she and Miguel share a kiss and playful banter. They instead work together to unite the students from Eagle Fang Karate and Miyagi-Do Karate. Over the week of Christmas, they convince the two dojos to work together by "parent trapping" them at the LaRusso family home. Their efforts at peace are derailed by a surprise attack from the Cobra Kai dojo.

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 fight Tory 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. Eagle Fang and Miyagi-Do merge for the sake of training, bringing Daniel and Johnny together as joint senseis. Sam stands by Miguel as they resume their training, preparing for the the tournament against Cobra Kai Dojo.

Personality

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.

After defeating her ex boyfriend Kyler and the latter gang when they were mocking Sam during season 1 of Cobra Kai, the two go on a date and become a couple. However, their relationship becomes strained when Sam does not want to bring him to her house to meet her family, due to Miguel being apart of Cobra Kai. Things get more strained when Sam does not respond to his texts. Unbeknownst to Miguel, Sam's mother took her phone away, which is why she is not responding. When Sam arrives to a party with Robby, Miguel wrongly assuming they are together, confronts Sam and attacks Robby, but accidentally hurting Sam in the progress, leading to her dumping him.

In season 2, the two don't have much interaction. Sam is upset over their break up in the beginning of the season, and wants nothing to do with him due to his actions. Sam however, would move on from Miguel and date Robby. Sam however, disapproves Miguel dating Tory because of their bad blood, and even confronts him on that, making Miguel upset. On the night before the first day of school, a drunk Sam thanks Miguel for returning Mr. Miyagi's badge of honor, and the two share a kiss, but immediately regret it due to them already being in relationships, but are unaware that Tory saw them. After Miguel is kicked off the railing by Robby the following day, Sam is horrified. At the hospital she tearfully says that she hopes Miguel is ok.

Later in the season, Sam and Robby go to a party together. When they arrive at the party, they're seen holding hands together, but this angers her current boyfriend Miguel, which cultivates in Miguel accidently hitting Sam when attempting to attack Robby, causing Sam to dump him.

In season 2, Robby moves in to Sam's house after his mom takes off with a guy. This along with both being in Miyagi Do, causes them to have more interactions. They develop feelings for each other and eventually become a couple. However, on the night before the first day of school, a drunk Sam kisses Miguel, without Robby's knowledge. When Tory exposes the kiss the following day at school, Robby is shocked. Despite learning the fact that she kissed Miguel, Robby is still loyal and protective of Sam. At the end of the school fight, Sam sees that Robby kicked Miguel off the school railing which makes Miguel unconscious. Sam asks Robby, "what did you do."

When Sam is interviewed about the fight in the beginning of season 3, she defends Robby by saying that Miguel being kicked off the railing was an accident. While Robby is in Sylmar Juvenile Corrections (SJDC) serving time for kicking Miguel off the railing, Sam emails him several times to check up on him, but eventually stops after he doesn't respond. She however, is unaware that Robby isn't writing due to him constantly being harassed by Shawn and his gang. After eventually being released from juvie, he goes to Sam's house, but sees her sparring with Miguel and in a compromising position, and then accuses her of cheating. Sam defends herself, but Robby doesn't believe her. When Miguel defends her, Robby tries to attack him, but is stopped by Sam. Robby then ends their relationship and walks out, saddening Sam.

Tory Nichols

Tory is Sam's biggest rival. It has been shown that the two girls are quite opposite, Sam comes from a wealthy home and has more of girly girl sense of fashion, while Tory's family lives in a poor lifestyle and is some what of tomboy, as well as both have different view of philosophy. Tory has a strong hatred for Sam, for having privilege life and as well for her being the ex-girlfriend of Miguel, this has lead her to bully and insult Sam.

While both on the ground, Tory attempts to tear Sam's face, however Sam quickly blocks it and kicks her down the stairs making Sam win the fight more honourably.

In season 3, The school fight and the scars on her arm has left Sam to have PTSD and fear Tory.

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 realises 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.

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.

In season 2, 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, Aisha tells Sam that Miguel returned Miyagi's Medal of Honor which shocks Sam.

She encourages Demetri and some of the other Miyagi Do's to get aggressive with the Cobra Kai's during a school soccer game, but this gets them detention. After Nathaniel is beaten up by Cobra Kai, Sam re-opens Miyagi Do, with Demetri rejoining. When Hawk is on the verge of breaking Demetri's arm during a fight at the arcade, Sam doesn't attempt to stop him, as she freezes out of fear when Tory calls out her name. After Hawk breaks Demetri's arm, Sam is shown to be very guilty. Sam's guilt over not helping Demetri haunts her for a while. In the finale, when Sam tries to get Miyagi Do and Eagle Fang to work together, Demetri along with most of the group disagrees, but ultimately everyone comes to an agreement, leading to the dojos merging.

In Season 3, Amanda looks after Sam and tries her best to help her through her PTSD while Daniel was busy dealing with the problems. Amanda bans Sam for doing karate and she attempts to appeal Sam's two week suspension in Aftermath but the school board decline the appeal which infuriates Amanda. Amanda then finds out about the physical contact soccer game between Cobra Kai and Miyagi-Do and she berates Sam for doing karate without permission and also saying she could've got suspended again but Sam tells her that she doesn't know what is going on with the rivalling dojo's. 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. Amanda then allows Sam to continue with karate as she better understands that John Kreese is responsible for fanning the flames of the rivalry between the two dojos and what Sam is experiencing.

Unfortunately, when Sam was just nine years old on November 15, 2011, Mr. Miyagi had passed away.
