Miguel "Miguelito" "Miggy" Diaz is one of the main characters in Cobra Kai.
He is Johnny Lawrence's bullied teenage neighbor who convinces the former karate champion to train him. Miguel quickly becomes the top student at the newly reopened Cobra Kai Dojo and is responsible for the influx of students that followed. Miguel's path while under the leadership of Johnny takes many turns, as he falls into the classic Cobra Kai mindset of "no mercy".
Despite being briefly corrupted, Miguel is able to correct the error of his ways thanks to Johnny's amendment of the "no mercy" mentality. However, when he does show mercy during an intense fight against Robby Keene, it results in a spinal injury. Miguel is rendered comatose for weeks until he awakes, ready to rebuild his life. Following his recovery, he sides with Johnny against John Kreese and becomes a part of Johnny's new dojo, which eventually merges with Miyagi-Do Karate in order to defeat Cobra Kai.

Miguel was born in Ecuador on June 17, 2002, to Carmen Diaz and an unnamed father whom Miguel, his mother and grandmother fled from because he was a criminal with implied connections to a drug cartel. It's unknown if Miguel's father knows about him.
A naïve, asthmatic 15-year-old with little self-defense reflexes, Miguel is attacked by a group of rich bullies led by Kyler while shopping in a bodega. When the bullies shove Miguel onto Johnny's car, Johnny, who happened to be sitting outside the bodega, confronts them and ends up fighting them before being arrested.
Although Miguel asks Johnny to train him, Johnny refuses until he decides to restart Cobra Kai, and Miguel becomes Johnny's first student in the new dojo. Aside from learning karate, Miguel becomes the dojo's janitor and website administrator. In short time, Johnny becomes a father figure to Miguel, despite objections from Miguel's concerned mother.
Miguel is determined and improves quickly under Johnny's tutelage. When Samantha confronts Kyler over rumors he spread about her, Miguel comes to her aid and defeats Kyler and his clique, gaining popularity in the school and earning Johnny's respect. He and Samantha become a couple, which becomes an issue later as Sam is Daniel LaRusso's daughter and Miguel is Johnny's student. Unfortunately, Cobra Kai's philosophy begins to affect Miguel's values as a series of misunderstandings with Samantha and Robby encourages him to become much more violent and ruthless, which results in Samantha ending their relationship and a rivalry between him and Robby to form.
At the All Valley Karate Tournament, Miguel reaches the semifinals along with Eli Moskowitz (Hawk), a fellow Cobra Kai. In the semifinals, Miguel defeats the defending the champion Xander, thus allowing him to advance to the finals. Prior to the finals he apologizes to Samantha for his behavior, but when Samantha rebuffs him for the way he has been acting, Miguel defends his actions and threatens to hurt Robby in the final, which causes Samantha to leave the tournament. During the finals, Miguel viciously attacks Robby's shoulder--the one Hawk had injured in the semifinals. However, even with his injured shoulder, Robby is able to tie the score at 2. When Robby tries to help Miguel up, Miguel instead yanks Robby's arm and further injures his shoulder, and the referee warns Miguel for unsportsmanlike contact. When Johnny tells Miguel to avoid Robby's right arm and that he can win without fighting dirty, Miguel's response is "there is nothing dirty about winning", which shocks Johnny. Miguel manages to defeat Robby, thus winning the tournament for Cobra Kai. Following his victory, Miguel hugs his mother and grandmother, but is also upset to learn from Demetri that Samantha left.
Despite being one of the primary characters and focuses in season 1, this season sees his role reduce significantly.
Both Miguel and Hawk are scolded by Johnny for their cheating/cheap moves during the tournament, stripped of their black belts, relegated to white belts along with the rest of the class, and forced to do 50 push-ups under Johnny's order. When Miguel confronts Johnny about the punishment, Johnny explains to him that when he was younger, he did not show mercy or honor and eventually paid the price, and the reason he is being tough on Miguel is so that he can be a better man than Johnny ever was.
At first he wants to talk things over with Sam. He sends her some apology texts, but she doesn't respond. Sam later blocks him, making him further guilty and upset. However, he soon meets a new Cobra Kai student named Tory, and over time they become a couple. However, it's quite clear the girl he truly loves is still Samantha.
While dropping off some of his mom's food at Johnny's apartment, Miguel notices a picture of Robby on the fridge. He tells Hawk, and the two find out that Robby is Johnny's son. They assume that Johnny is only being hard on them because of his relationship to Robby. They confront Johnny, but the latter angrily tells them to mind their own business. However, Johnny later tells Miguel how he screwed up with Robby, and that he is proud to now be teaching Miguel, which makes their bond stronger and helps Miguel realize that Johnny isn't favoring Robby over him.
During a competition in the woods hosted by Johnny's sensei John Kreese, Miguel finds out that Hawk was the one who instigated the vandalism of the Miyagi dojo and stole Mr. Miyagi's Medal of Honor, and Miguel uses the training exercise to defeat Hawk and takes the Medal. He goes to Sam's house to return it, but when Robby opens the door Miguel gives the Medal to him instead, trusting that he would give it to Sam.
As the relationships between Miguel and Tory and Sam and Robby progress, they cross paths at the rollerskating rink where Tory works. There Miguel realizes that Sam and Robby are there as a couple. Tory sees this too, and she provokes Sam by kissing Miguel in front of her, making Sam jealous. Miguel and Sam then have an argument about why he is dating Tory, followed by Tory and Sam get into a physical altercation resulting in Tory falling. This leads Miguel to defend Tory against Sam, and Sam and Robby are kicked out of the rink.
During Moon's house party on the last day of summer vacation, the feud continues in a drinking contest between Tory and Sam, which results in a drunken Sam. During a quiet moment together, Sam realizes that Miguel was the one who gave back the Medal, and she thanks him. Then the two share a kiss, which they both immediately regret. However, they are unaware that Tory sees them.
When a school fight starts on the first day of school, Miguel sees Robby holding Tory against a locker. Unaware that Tory was attacking Sam before and Robby was trying to stop the fight, Miguel tackles Robby and the two fight. After gaining the upper-hand on Robby, Miguel notices Sam and Tory fighting. He runs to stop the fight, but is stopped by Robby who attacks him. With the assistance from two of his Cobra Kai friends, he manages to kick Robby into one of them who grabs hold of Robby. After being encouraged by his friend to go, Miguel runs to Tory and Sam, leaving Robby to deal with his two friends. After reaching Tory and Sam, he tries to stop Tory from attacking Sam, only for Tory to kick him in he face, causing him to have a bloody lip.
After Robby defeats Miguel's friends he runs to help Sam, only for Miguel to stop him. They then continue their fight, Their fight seems to be even. At times Miguel has the upper-hand and at times Robby has the upper-hand. After gaining the upper-hand on Robby again, Miguel tells Robby that Sam loves him more than Robby, causing an infuriated Robby to aggressively attack Miguel and gain the upper-hand yet again. Miguel, however, manages to recover and get the better of Robby by flipping him over and trapping his arm in a lock. After seemingly winning the fight, he decides to show mercy due to Johnny's teachings. He lets go of Robby's arm and apologizes (possibly for kissing Sam). However, an infuriated Robby, who is likely still angry at Miguel for kissing Sam, gets up and kicks Miguel, who flips over the railing he was backed-up against. Miguel is admitted into the hospital in critical condition.
Miguel has a broken spine as a result of Robby accidentally kicking him over the railing, and he is paralyzed for a few weeks until Season 3, Episode 7, a few days before Robby gets out of the juvenile detention center.
This season sees Miguel as one of the key characters, similar to season 1.
While in a coma, Miguel is dreaming about fighting and beating an opponent in the All Valley tournament, but eventually he wakes up. His legs, however, aren't functioning. While he is supposed to have surgery, it is unknown whether this will help him to walk again. Initially, Miguel blames Johnny for being in this position, but after some time Johnny starts giving hope to Miguel.
After Miguel is released from the hospital, Johnny begins performing exercises with him in order to help get his legs functioning. Initially, the exercises aren't working, frustrating Miguel. However, while at a concert, Johnny and Miguel witness Miguel being able to tap his foot, giving eveyone some hope. Johnny continues to work with Miguel, sometimes with unorthodox methods, especially in comparison to the physical therapy Miguel also receives. At the same time, Miguel helps Johnny with a Facebook profile.
While at a restaurant helping Johnny with photos for his Facebook profile, Tory sees Miguel. He expresses that he's upset that Tory did not come to visit him while he was in the hospital. He also does not like when Tory says that Cobra Kai is trying to get back at Miyagi-Do for what happened to him, since he does not see it as Miyagi-Do's fault. At the same time, Tory voices her disappointment for his kiss with Sam. Miguel still does not see this as justifying the fight Tory caused and the brutality with which she faught Sam, and he tells her that she needs help, which angers Tory, as she feels he is calling her crazy. When Miguel ends their relationship, Tory leaves upset and in anger. Later that day while training with Johnny, Miguel lacks motivation, which annoys Johnny, who does not know that Miguel is struggling because he is upset about his breakup with Tory. The two get into an argument, with Miguel accusing Johnny for giving up on his students. After he finishes his ranting, Johnny points out to Miguel that he is standing without assistance, making them both happy and causing them to hug. From then on, Miguel continues to improve with Johnny's training. Miguel goes from a wheelchair to crutches and eventually walking on both feet without the need of any support.
Now, that Miguel can walk again, he goes back to school, but not before telling Johnny he will help recruit students to Johnny's new dojo, which Johnny calls Eagle Fang Karate. At school he rekindles his friendship with Sam, and expresses disappointment in Hawk after learning from Demetri that Hawk broke Demetri's arm. Miguel's and Hawk's friendship ends as a result of Hawk's ruthless actions. Luckily for Miguel, some of his classmates join Johnny's dojo such as Mitch and Bert. They begin training together, but Miguel still struggles with his recovery. He hurts himself while attempting to kick in training, but Johnny tells him that it's alright and that no one expects him to be back to his normal self. After Mitch gets news that All Valley is cancelled, Johnny tells Miguel it's okay, since he would not have been able to compete anyway, which angers Miguel who protests and wants to defend his champion title. Johnny tries to make Miguel understand that he does not want to risk Miguel getting hurt again, but Miguel is adamant on competing and defending his title. The conversation ends with Miguel storming into his apartment and Carmen talking to Johnny about her believing in him saving the All Valley Tournament.
In the community hearing about the tournament, Councilperson Roberts is summarizing that the All Valley Tournament should be banned because of the school brawl and the City Council thinking that karate is the problem, but then Miguel shows up. Miguel points out to Roberts that he was involved in the school fight, and that he was the one who was kicked off the second floor balcony and was paralyzed as a result, and he tells the Council that it was Johnny who helped him walk again. He then explains to the Roberts that he was bullied and how karate is a means of teaching kids to defend themselves, and that tournaments are safe places to practice these skills. He also credits Johnny for his success. He is joined by Sam who makes similar arguments. Miguel ends his case by saying that the All Valley should be allowed to be held to give the kids ways of defending themselves. Moved by their pleas, Councilperson Roberts allows the tournament to resume, making both Miguel and Sam happy and hug.
Back at Sam's house, Miguel and Sam are chatting and celebrating their accomplishment of saving the tournament, and Miguel jokingly gives Sam a hard time about Miyagi-Do. Miguel even teases her into taking him down a second time, reminding of their first date. The two briefly spar, but then stop and stare at each other (romantically). Unfortunately, in that moment Robby walks in on them together, having come to see Sam after his release from juvenile detention center, and he accuses Sam of cheating on him with Miguel. Miguel tries to calm Robby down, tells him it isn't Sam's fault and points out how Robby wasn't there for Sam when she had panic attacks and PTSD from Tory's attack and teh school fight, but Robby angrily tells Miguel to stay out of it. Miguel refuses to do this, and it becomes clear that the rivalry from season one continues. Robby then reignites their rivalry and attempts to punch Miguel, but Sam blocks his punch and pushes Robby away, while telling him to stop. Robby angrily states that they deserve each other and then breaks up with Sam. This leaves Sam devastated and Miguel shocked over nearly being attacked by the same person who put him in the hospital.
The following morning, Miguel and Sam are inside the Miyagi-Do dojo, where Miguel is looking at a picture of Mr. Miyagi and holding Daniel's Okinawan hand drum. Sam asks Miguel to put the drum in his pocket and attack her. Miguel does so, but is blocked by Sam the same way Daniel blocked Chozen's attacks in Karate Kid 2. Miguel then performs a take down, causing both to fall. On the ground, the two kiss, but they are walked-in on by Daniel LaRusso. Although initially tense, the relationship between Daniel and Miguel softens as the two bond over the car Daniel got from Mr. Miyagi. Daniel tells Miguel certain facts about Johnny and his rivalry with Johnny, which Johnny never told Miguel, helping Miguel realize both sides to the rivalry between the two senseis.
Later that night, Sam invites Miguel and the other Eagle Fang students to her house while Amanda and Daniel are out in the Country Club Dinner with Ali and Johnny. She wants all of them to work together, which no one can agree upon except Sam and Miguel. However, after some discussion they agree and unite. Just in time, since Tory interrupts the "party" with a group of Cobra Kai students, including Kyler. Miguel is especially unhappy to see Kyler has joing Cobra Kai due to his past bullying. The Cobra Kai then attack, resulting in a fight. Miguel first pins Mikey to the table, but then faces Kyler. Kyler has the upper-hand for most of the fight due to Miguel still recovering from his fall off the balcony and only recently returning to training. However, while being repeatedly hit by Kyler, Miguel remembers the encouragement Johnny gave him while in the coma and his dream about competing in the tournament, as well as imagining Robby as his opponent. Now, regaining his confidence, Miguel defeats and knocks out Kyler, and thanks him for the motivation.
Back at Cobra Kai, when Daniel is getting the better of Kreese, Miguel and Sam show up and stop the fight between them. Robby arrives and stands next to Kreese, siding against his old sensei and father in the same move, and shocking Daniel and Johnny. Robby angrily shouts at Miguel, Sam, Daniel and Johnny and tells the four to leave. The following morning, Miguel and the other Eagle Fangs show up at the Miyagi-Do dojo, where they begin training under Johnny's and Daniel's leaderships in preparation for the tournament against Kreese, Robby, Kyler, Tory. Mikey, Doug, Big Red and the rest of the Cobra Kais.
Miguel initially appears as a naïve, good-natured, kind-hearted teenager. He is depicted similarly to Daniel LaRusso in the Karate Kid series before the latter joined the Cobra Kai. Miguel beocmes much like a hybrid of Johnny and Daniel from the first Karate Kid film, and the change of character he goes through is significant. Initially, Miguel will only fight for those he cares about, for example defeating Kyler and his gangs after they insult Sam. He goes from being a nice kid who was incessantly bullied to an aggressive karate champion who makes his former tormentors afraid to be around him. More negative tendancies begin when he is convinced that his girlfriend, Samantha, thinks he's not worthy of meeting her family, or was secretly seeing someone else instead (Robby). Miguel proceeds to show more aggression and less sportsmanlike behavior in the All Valley Tournament. It is suggested that Miguel's transformation from a mild-mannered and pleasant person into a vicious and obsessively competitive individual represents the way that Cobra Kai's "strike first" and "no mercy" rules corrupt innocents and turn them into antisocial bullies.
Despite becoming indoctrinated into Cobra Kai's "Strike First, Strike Hard, No Mercy" code in the end of season 1 and during the tournament, he being corrected by Johnny seems to calm Miguel down. He's still a nice kid that respects his sensei and stays loyal to his friends. This is also later shown where he initially rebuffs Kreese's teachings, realizing that's not what Johnny wants them to learn. After discovering that Hawk vandalised the Miyagi-Do dojo and stole Mr. Miyagi's Medal of Honor, Miguel defeats Hawk in combat, takes the Medal and goes to Sam's house to return it, showing his decency, honor and understaning the value of the Medal, despite his prior actions and Cobra Kai's ruthless mentality. Although initially still interested in getting back together with Sam at the beginning of season 2, Miguel soon meets a new Cobra Kai student named Tory, and the two start dating, and Miguel manages to bring out Tory's softer side. When he and Sam kiss at Monn's party, he knows it is wrong and still shows his loyalty and connection to Tory by worrying about her whereabouts in the ensuing panic when the arrival of police breaks up the party. At the end of the season, Miguel reveals that he adopted Johnny's adapted code of showing mercy in the fight against Robby during the school brawl, but this does not save him from being badly injured.
In the beginning of season 3, Miguel blames Johnny for being in his situation (hospitalized and not able to walk), and he feels hopeless about ever walking again. However, with Johnny's encouragement and training, Miguel recovers and is able to walk again. After returning to school, he rekindles his friendship with Sam, and shows disappointment in Hawk's latest behavior and actions, completely turning his back on Kreese's old methods for Cobra Kai and embracing Johnny's modified teachings. He soon rekindles his relationship with Sam and becomes a part of Johnny's new dojo, as well as learning to reconcile what Johnny has told him with his new understanding of Daniel LaRusso upon meeting him for the first time. During his fight with Kyler at Sam's house, he is losing most of the time due to him not being back to full form, but after remembering Johnny's encouraging words, he gains his confidence back and defeats Kyler, revealing his determination and strength. The seasons ends with Johnny's and Daniel's dojos merging into one, making Miguel a part of Miyagi-Do.
- "Yeah, it all happened so fast. Everything just came together. I was blocking. I anticipated. I slithered."
- ―Miguel Diaz to Johnny Lawrence[src]
After he begins his karate training with Johnny, Miguel develops into a solid all-around fighter. Not as flashy as Eli Moskowitz, Miguel favors simple, effective techniques and combinations. His defensive skills, movement, and timing are excellent; he can wait out an aggressive opponent and pick the right moment for a counter, as seen in his match with Xander Stone. Like any true Cobra, however, he can turn on the offense when he needs to. He is also skilled against multiple opponents, as displayed in his lunchroom fight with Kyler's gang.
When his anger gets the better of him, Miguel fights more aggressively and underhandedly, evidenced during his fights with Robby at the All Valley Tournament and school brawl, though he also knows when to fight a fair fight and show mercy. Miguel has fought underhandedly, evidenced at the All Valley Tournament, where he aggressively attacks Robby's injured shoulder (in a manner not too dissimilar to Johnny Lawrence underhandedly attacking Daniel LaRusso's injured leg in the 1984 All Valley Tournament), and even yanks it in the finals.
Miguel's biggest weakness is letting his guard down, which allows his opponents to attack him by surprise and beat him. After gaining the upper-hand on Tory in their sparing match, he ends up dropping his guard by offering Tory his hand, who uses this opportunity to flip him over and beat him. After seemingly beating Robby in the school brawl, he drops his guard by letting Robby go. However Robby then viciously attacks Miguel, who is unable to defend himself due to dropping his guard, resulting in Robby unintentionally rendering him unconscious and severely injuring his spine.
While Miguel defeated Robby in the All Valley tournament in season 1, their match was basically even despite Robby's injured shoulder putting him at a disadvantage. Miguel resorts to attacking the shoulder to win, indicating that he may not have won if he hadn't fought dirty, and that Robby may have won if he had not been injured. Their fight and the result suggests that Miguel was an inferior and less skilled fighter than Robby. In the school brawl in season 2, however, Miguel successfully pins Robby to the ground without fighting dirty, showing that Miguel is a more skilled fighter than he was in season 1, as well as that he was the better and more skilled fighter than Robby at that time. Arguably, however, Robby was angry and not focused because Miguel said that Sam loves him more than Robby, which is what gave Miguel the upper-hand on him.
Miguel's physical strength has come a long way since he began his training. Near the end of the school brawl, he dented a metal railing when he attempted to kick Robby.
In season 3, he doesn't start training until later on due to his injury in the season 2 finale. When he starts walking and training again, his kicking is weak and he almost hurts himself, due to his legs not being back to full strength. Since his legs are not back to full form, this puts him at a disadvantage in his fight with Kyler, until he regains his confidence, with the latter then allowing him to defeat Kyler.
Miguel is likely the best and strongest next generation student among the three dojos (Miyagi-Do, Eagle Fang and Cobra Kai).
Carmen is Miguel's mother. Both of them have a close relationship and care for each other. However, Carmen is often overprotective of Miguel, especially after he decides to do karate. While she forbids him from doing karate after he is beaten up by Kyler and his gang, she is then persuaded by Johnny to let him do it. Following this, she doesn't seem to be as protective, though she seems ambivalent about the violence that continues to be involved. In the end of Season 1, she is seen cheering on Miguel from the beginning to the finals of the All Valley Tournament. However, in Season 2, after the school brawl, Miguel is admitted to the hospital due to the fight with Robby, and Carmen is shown to be distraught and extremely distrusting of Johnny.
In season 3, Carmen is with Miguel in the hospital before and after he wakes up from his coma. After waking up from his coma, she is there to make sure he is ok. After Miguel is released from the hospital, one does not see a lot of their interaction, but Carmen eventually expresses her appreciation to Johnny for helping Miguel recover and walk again, and Johnny and Carmen get back together.
Rosa is Miguel's maternal grandmother. Rosa supports his decision to do karate. In the end of Season 1, she is seen cheering on Miguel from the beginning until the finals of the All Valley Tournament. In Season 2, she is concerned when Miguel is admitted to the hospital after being kicked over the railing by Robby.
In the beginning of season 3, when the nurse tells Rosa and Carmen to remind the comatose Miguel that they are there and to talk about things he loves, Rosa talks to Miguel about his favorite sports teams. While this is the only interaction in the season, shortly after Miguel wakes up from his coma, Rosa is the one who asks Johnny to be there for Miguel, and reminds him that that Miguel needs him, as well as pleads him to pray with her, which Johnny accepts.
Johnny is Miguel's karate sensei and a father figure. When they first meet in Season 1, Johnny is rude to Miguel. However, one night at Reseda Mini Mart, Johnny engages in a fight with Kyler and his gang for harassing Miguel, though it's not clear it this is because he wants to help Miguel, or because Miguel accidentally hit Johnny's car. Miguel attempts to explain to the police that come to arrest Johnny that it wasn't his fault, he did not just attack the teenagers, which reveals his growing attachment to Johnny. The following morning, Miguel asks Johnny to teach him karate, but Johnny refuses to teach him at first. Later, Johnny changes his mind when he reopens the Cobra Kai dojo.
In many ways, Johnny becomes a Mr. Miyagi to Miguel, who is more often remniscent of Daniel than Johnny. Johnny passes on his Halloween skeleton costume idea to Miguel, though their situations are reversed from Johnny and Daniel in the original The Karate Kid. This time, Miguel is the one badly injured by Kyler and his gang, and Johnny is the one to find Miguel and bring him safely to his apartment. This results in Carmen wanting to forbid Miguel from continuing karate and coming near Johnny. After some time, Johnny realizes that he truly cares about Miguel, who is one of the only people who hasn't given up on him. So, he then persuades Carmen that she should let him back into his dojo and he promises not to fail him. Carmen agrees to let Miguel do karate again, but only if Johnny makes sure that next time Miguel will be able to defend himself.
With Johnny's training, Miguel becomes a skilled fighter, which allows him to defeat Kyler and his gang, resulting in several students joining Cobra Kai and Johnny even giving his old gi to Miguel as a reward. Miguel and Johnny bond over the course of season 1, with Johnny even giving Miguel advice on dating Daniel's daughter. In the season 1 finale, Johnny expresses discomfort when Miguel fights dirty against Robby in the All Valley Tournament. While he advises Miguel not to fight dirty, he continues to anyway, which allows Cobra Kai to win the tournament. Despite the victory, Johnny feels bad about what Miguel has become.
In season 2, Miguel and Hawk are rebuked and punished by Johnny for their dirty tactics in the tournament. When Miguel confronts him, Johnny says he paid the price for not knowing the difference between honor and mercy, and wants Miguel to avoid making the same mistake. Their bonding continues, with Johnny even telling Miguel that he is proud to be teaching him. In the finale, Miguel gets the better of Robby, but lets him go after remembering Johnny's advice. However, this backfires, as an enraged Robby attacks Miguel and Miguel flips over a railing, rendering him unconscious and severely injuring his spine. At the hospital, Johnny listens to a voicemail Miguel left earlier and peeks into Miguel's room and sees him lying unconscious, causing him to cry and feel guilty.
When Miguel wakes up from his coma in the beginning of season 3, he is cold to Johnny at first, as it was Johnny's teachings that he followed that led to him ending up in the hospital. However, after some time, Johnny begins giving a hopeless Miguel courage, and they become close again with Johnny helping Miguel return back to training and Miguel helping Johnny with his dating and social life via facebook and accepting that Johnny was seeing his mother. When Miguel is released from the hospital, Johnny works with Miguel to help him walk again through training, and eventually Miguel begins to walk again. After being able to walk, he joins Johnny's Eagle Fang Karate dojo. By the end of the season, The Eagle Fang and Miyagi Do dojos have merged, and Miguel along with the rest are training at Miyagi-Do with Johnny and Daniel as the co-sensei's.
Samantha is Miguel's girlfriend part of season 1 and part of season 3, and she plays a similar role in the rivalry between Miguel and Robby that Ali played between Johnny and Daniel in The Karate Kid. On his first day of school, Sam catches Miguel's eye and he wants to approach her, but he is interrupted by Kyler. After defeating her ex-boyfriend Kyler and his gang during the lunch altercation, the two go on a date and become a couple. Their relationship mascot is an octopus from the prize Sam earned on their first date together. However, their relationship becomes strained when Sam does not want to bring him to her house to meet her family, due to Miguel being a member of Cobra Kai, which is the rival dojo to her father's Miyagi-Do. Things get more strained when Sam does not respond to his texts, though this was not Sam's fault. Unbeknownst to Miguel, Sam's mother took her phone away. Still, she eventually manages to get a hold of her phone and wants to meet Miguel at the party, which she arrives at with Robby. Seeing this, Miguel assumes they are together, confronts Sam and attacks Robby, but he accidentally hits Sam instead. After this, she asks Miguel to leave her alone and their relationship ends for the rest of season 1.
In season 2 , the two don't have much interaction. Initially, Miguel wants to make things right and rekindle their romance, but Sam wants nothing to do with him due to his actions. When spending more time with Tory, he falls for her and starts dating her instead. Sam, however, has bad blood with Tory and disapproves of Miguel dating her. She even confronts him about it, upsetting Miguel. On the night before the first day of school, a drunk Sam thanks Miguel for returning Mr. Miyagi's Medal of Honor, and the two share a kiss, but immediately regret it due to them already being in relationships. They are unaware of the fact that Tory saw them, which is what leads to Tory attacking Sam the next day in school, and to the fight between Miguel and Robby. After Robby flips Miguel over the railing, Sam is horrified both at what Robby did and Miguel's condition. At the hospital she tearfully says that she hopes Miguel is ok.
Shortly after waking up from his coma in season 3, Sam visits him and gives him a get-well card, and the two apologize to each other for the whole situation. After Miguel is able to walk again, he returns to school and rekindles his friendship with Sam. Over time, they rekindle their former romantic feelings for each other and end up back together. Sam and Miguel work together to bring Eagle Fang and Miyagi-Do together, and by the end of season 3, Miguel is training with Sam and the other Eagle Fangs and Miyagi Dos at the Miyagi-Do dojo.
Tory is Miguel's love interest in season 2. With Miguel initially being upset over his breakup with Sam, Tory, who had joined Cobra Kai and taken interest in Miguel, helps him get over his breakup. The two quickly become a couple, and while Miguel does not know the full extent of Tory's family background, he knows she works hard, and he s willing to defend her behavior against the criticism of others. Tory also has an influence on Miguel about what can be considered fair or not fair in fighting and in life. However, Tory witnesses Miguel and Sam kissing the night before the first day of school. In the school brawl that she instigates, Tory, still angry over the kiss, kicks Miguel's face when the latter tries to stop her from attacking Sam. She is horrified, however, when Miguel is kicked over the railing by Robby.
The next time they see each other is while Miguel is at lunch with Johnny, who is posing for pictures for his Facebook profile. Tory sees him when Johnny goes to the bathroom. Miguel shows that he's upset with Tory for not coming to visit him in the hospital. He is further upset when Tory says that Cobra Kai is trying to get back at Miyagi-Do for what happened to him, while Tory voices her disappointment for his kiss with Sam. Miguel tells her that she needs help, but this angers her, as she feels he is calling her crazy. Miguel then breaks up with Tory for her role in severely injuring Sam and starting the school brawl, and then she leaves in anger. The next time they see each other is when the Cobra Kai students enter Sam's house in order to attack the Miyagi Do and Eagle Fang students who had just formed a truce. Miguel tells Tory she doesn't have to do this, to which Tory says "it's too late". Then a fight breaks out, which Cobra Kai loses. Before Tory leaves, she calls both Miguel and Hawk traitors.
Aisha is Miguel's friend. The two become close friends when Aisha joins the Cobra Kai Dojo, since for a while they are the dojo's only two students. Miguel plays a role in convincing Johnny to take her on as a student. Initially Miguel is careful about sparring with Aisha, and it is implied this is because she is a girl, but she quickly relieves him of this misguided thinking. When Johnny tells Miguel to do everything he has learned to attack Aisha, he seems to be apologetic for attacking her, but Aisha strikes him back.
While they don't have as much interaction in season 2, they are still friends. Also, Aisha is the one who tells Sam that Miguel was the one who returned the Medal of Honor.
Hawk is one of Miguel's closest friends. They meet in the school's cafeteria, where Demetri introduces them, and immediately become friendly due to being somewhat outsiders and bullied by Kyler and his gang. Eli joins Cobra Kai after witnessing Miguel using his skills from Cobra Kai training to beat up Kyler and his gang. After becoming Hawk, he would go on to become one of the top students along with Miguel. Despite Hawk's abrasive personality and actions, as well as the two getting into a fight over Mr. Miyagi's Medal of Honor that Hawk stole, they remain close friends. At the end of the fight, when Miguel has fallen from the second story balcony. Hawk immediately recognizes Robby as the one responsible for this. He is also one of the first at the scene on the stairs and tries to wake Miguel up, but a policeperson tells him to back off. Hawk believes that their sensei, Johnny, is indirectly responsible for the situation Miguel is in.
In Season 3, Hawk is one of the people who regularly visits Miguel in the hospital. He interrupts Sam's visit to Miguel and keeps the rivalry between Cobra Kai and Miyagi-Do alive, extending so far as to organizing the theft of the fundraising money for Miguel's surgery (though it is implied that the money does become contributed to the costs of the surgery in Cobra Kai's name). After Miguel is able to walk again, he returns to school, where he is welcomed back by Hawk. However, after learning from Demetri that Hawk broke Demetri's arm, Miguel confronts Hawk and shows disapproval about him letting Kreese get inside his head. Hawk's latest actions lead to their friendship ending. However, it is assumed that their friendship is rekindled when when Hawk redeems himself by defecting from Cobra Kai and becoming part of Eagle Fang, joining forces with Miyagi-Do.
Demetri is one of Miguel's friends. They meet in the school's cafeteria and immediately become friendly due to being somewhat outsiders and bullied by Kyler and his gang. After Miguel uses his skills he learned at Cobra Kai to beat Kyler and his gang, Demetri reluctantly joins Cobra Kai, but has trouble participating due to his lack of athleticism and more passive nature. He ends up quitting after Sensei Kreese hurts him. Despite quitting, which upsets Miguel, the two are still close. In season 2, the two rarely interact due to Demetri joining Miyagi-Do, though the two are probably still friends.
At first in season 3, Demetri buys Miguel a comic book as a get better present. Then, when Miguel first meets Demetri at school, he is concerned when he sees his broken arm, and Demetri tells him about what Hawk did to his arm. By the end of the season, the two are training at Miyagi-Do with the other Miyagi-Do and Eagle Fang students.
Robby and Miguel have tense relations from the start. One could say he is Miguel's main rival. While the two don't have much interaction, they never have a positive one. Both dislike each other since their separate and unaware moments of first seeing the other. Their rivalry is similar to Daniel and Johnny's original rivalry, but on more personal levels. Miguel hates Robby for stealing Sam away and Robby hates him for stealing his father, who is Miguel's sensei. In the penultimate episode of season 1, Miguel and Robby meet at a party, where Miguel has gotten drunk out of desperation over Sam not returning his texts or calls. When Miguel sees his girlfriend and Robby walking together to the party, he is immediately jealous. Getting the wrong idea, he attacks Robby, but accidently pushes Sam in the process, leading her to dumping him. In the season 1 finale, Miguel and Robby face off in the All Valley Tournament, where Miguel viciously attacks Robby's shoulder which was injured thanks to Hawk in the semifinals, allowing him to defeat Robby and win the tournament, though it was a close match.
In season 2, they don't have much interaction. When Miguel went to Daniel's house to return Mr. Miyagi's Medal of Honor that Hawk stole, he was shocked when Robby opened the door. He does not realize that Robby was not yet really together with Sam; he was there because the LaRusso's took him in after his mother abandons him for a short period. Still, Miguel gives him the medal, trusting that Robby will give it to Sam. Instead Robby, worried the admission would ruin his chances with Sam, pretends to find the medal in the Miyagi-Do dojo. Sam finds this out through Miguel at the party, but appreciates that Robby admitted it to her in the end before the school fight. When the school brawl starts, Miguel becomes involved when he notices Robby is holding Tory, Miguel's girlfriend, against a locker. Unaware that Robby was trying to stop the fight, as well as believing he was attacking her, Miguel attacked Robby, causing the two to fight. Their fight is long and intense, and it appears to be evenly matched. Eventually, Miguel flips Robby and put his arm in lock, but after remembering Johnny telling him to show mercy, he lets Robby go and apologizes. Unfortunately, an enraged Robby attacks him again and flips him over the railing, resulting in Miguel falling on the stairs below and suffering a broken back. Horrified at what he had done, Robby runs away.
Later in season 3, Robby, who was recently released from juvenile detention, sees Miguel, who is now walking again, with Sam. Getting the wrong idea, he tries to attack Miguel, only to be stopped by Sam. Robby then walks away and his relationship with Sam ends. Later, when Miguel and Sam show up at Cobra Kai to stop Daniel from further escalating his fight with Kreese, Robby comes out and tells all of them to leave.
Kyler and his gang are a group that bully Miguel in the first half of season 1. It starts when Miguel outs Kyler and his friends for trying to buy liquor while being underage. Their resulting attack on Miguel leads to Johnny becoming involved, and eventually to Johnny taking Miguel on as his first student. Since their first meeting, Kyler and his gang would frequently bully and harass Miguel. At the Halloween party, Kyler and his gang beat Miguel up so badly that Johnny has to help him get home, and it leads to Miguel's renewed efforts to gain enough strength to stand up to them. Eventually, when Kyler and his gang are harassing Sam in the cafeteria, Miguel defends her and is able to use his skills to defeat Kyler and his friends. Following his victory, Kyler is afraid to go near Miguel for the rest of the season.
In season 3, Miguel and Kyler first meet at the park when Kreese tries to persuade Johnny to rejoin Cobra Kai. The two glare at each other, realizing they are now students of rival dojos. They see each other again when Cobra Kai students come to Sam's house in order to fight Miyagi-Do and Eagle Fang, who had just formed a truce. Miguel and Kyler spend most of the fight fighting each other. Unfortunately, Miguel is at a disadvantage, as while he recovered from his injury enough to walk again, his body, most notably legs, aren't back to full form yet, combined with him only recently getting back to training. Kyler has the upper hand over Miguel for most of the fight, but when Miguel regains his confidence, he wins in the end by knocking Kyler out.
Daniel is Miguel's girlfriend's father and later his co-sensei. In Season 1, they see each other for the first time when Daniel goes to confront Johnny about Kyler being assaulted by Johnny. Johnny tells Daniel the truth about what happened, since it was really Kyler who had attacked Miguel. Daniel is shocked to know that Miguel is training under Johnny, and warns him not to be like him. Daniel tells his daughter to stay away from any Cobra Kai students, without knowing that Miguel and Sam are dating, which strains Sam's and Miguel's relationship. Miguel does not know about Daniel's advice about whom Sam should date, and he attempts to introduce himself to Daniel before thinking that Sam is actually interested in Robby, who happened to be eating dinner at the LaRusso house that evening.
On the other hand, Johnny was shocked to see Miguel is dating Daniel's daughter, and he decides to tell Miguel his side of the story about Daniel. This causes Miguel to dislike Daniel and not want to be associated with the LaRusso family.
Miguel and Daniel do not interact directly over the first two seasons, seeing as Miguel is Johnny's student, though they see each other at numerous occasions, including the All Valley Tournament. There, Daniel witnesses Miguel using his signature move, the Crane Kick, against the opponent in the preliminary round, much to his chagrin.
Upon meeting LaRusso for the first time after his recovery in season 3, Miguel starts to see that they have more in common than he previously believed, and he begins to respect LaRusso and his methods, as well as his perspective in the rivalry with Johnny. By the end of the season, Miguel trains at Miyagi-Do with the Miyagi Do's and Eagle Fang students, with both Daniel and Johnny as his co-senseis.
Miguel is one of the first people to doubt John Kreese's intentions when the latter shows up at Cobra Kai in seaason 2 and wants to co-lead with Johnny. He trains under Johnny and Kreese together, but is quick to note that some parts of Kreese's story don't add up. However, he accepts his sensei's judgement that Kreese has changed and that Johnny still has command of the dojo. Still, when Johnny is not available to teach, Miguel has difficulty trusting Kreese or his ruthless training tactics. He also has no problem leaving Kreese and Cobra Kai behind when Johnny goes to start his own dojo. For most of season 3, Miguel's interactions with Kreese are limited, but he is never happy to see Kreese.
- Miguel can speak fluent Spanish and English.
- He has an asthmatic condition that requires the use of an inhaler in the early part of season one, though it is implied that training strengthens his lungs and the condition loses severity for him.
- Robby and Miguel have fought each other twice, and both have won once through unethical tactics:
- Miguel won by attacking Robby's injured shoulder, which includes him yanking it when the latter attempts to help up him by offering his hand.
- Robby won by attacking Miguel and kicking him off the railing after the latter released Robby from a hold and apologized for their skirmish.
- Hawk nicknamed him El Serpiente ("the snake") for his first-place victory in the All-Valley tournament.
