Pre-Cobra Kai

Born October, 2002, 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 this angry man 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, though they have yet to label their relationship. 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.
