Miguel Diaz is one of the main characters in Cobra Kai. serving as a deuteragonist-turned final antagonist in Season 1 and a deuteragonist for Season's 2-4.
Miguel Diaz was born in The United States on November 22nd, 2002, to Carmen Diaz and an unnamed father whom Miguel never knew, Miguel's mom (Carmen) and his grandma left Ecuador before giving birth to him, because he was a criminal with implied connections to a drug cartel. It's said that Miguel's father knows nothing about him. Miguel is in the 11th grade.
Miguel is a student of Johnny Lawrence's Eagle Fang Karate (allied with Miyagi-Do Karate) and formerly the top student of Cobra Kai Karate which has since been taken over by John Kreese.
In season 1, 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 during season 2. However, when he does show mercy during an intense fight against Robby Keene in the season 2 finale, it results in Miguel's spinal injury.
In season 3, he is rendered comatose for weeks until he awakes, ready to rebuild his life. Following his recovery, he knocks out Kyler who has joined Cobra Kai and is an essential part of it with just 3 strikes before he becomes a part of Johnny's new dojo, Eagle Fang, which eventually merges with Miyagi Do Karate in order to defeat Cobra Kai.
He is portrayed by Xolo Maridueña.
Miguel and his family moved into the apartment complex where Johnny lived at. Miguel attempted to introduce himself to Johnny, but Johnny rebuffed him.
Later, while visiting the mini mart to pick up some Pepto Bismal for his grandma, Miguel accidentally outed Kyler and his cronies as not being college kids when they went to go buy beer. Miguel attempted to apologize, but Kyler and his crew began shoving him around, taking his Pepto Bismal and pouring it on his head as well as nicknaming him "Rhea" (short for diarrhea). However, after Miguel was shoved onto Johnny's car, Johnny stepped in and beat up Kyler and his gang.
Inspired by Johnny's karate moves, Miguel encouraged Johnny to open up his own karate dojo and teach him karate. Though Johnny initially shot down the idea, he later changed his mind and opened up his Cobra Kai dojo in the mini-mall, inviting Miguel to be his first student. The dojo would later receive a second student when Aisha joined.
When Kyler began harassing Sam LaRusso and lying by saying she performed oral sex on him, Miguel stepped in and told him to back off. Kyler responded by challenging him to a fight, at which point Miguel used his karate training to beat down Kyler and his three cronies, impressing Sam and the whole lunchroom. The fight was filmed and uploaded to YouTube where it went viral, resulting in tons of publicity for Cobra Kai.
Miguel eventually began dating Sam, though their relationship became strained by Sam's father Daniel LaRusso's dislike of Cobra Kai. Later, after getting drunk at a Cobra Kai party in a canyon, Miguel got into a misunderstanding with Sam where he assumed Robby Keene was her boyfriend and accidentally hit her while trying to attack Robby, resulting in their relationship breaking up.
Miguel and Cobra Kai later entered into the All Valley Under 18 Karate Tournament which Robby also entered into as an independent fighter. Miguel and Robby would face off in the final round, though by exploiting an injury Hawk had inflicted on Robby out of turn, Miguel was able to beat Robby and win the tournament for Cobra Kai. As the announcer went up to give Miguel the first place trophy, Miguel dedicated his victory to Johnny Lawrence and Cobra Kai.
However, Miguel and Hawk were both punished by Johnny for using a cheap shot to win and made to do 50 push-ups on their knuckles. Though initially still hung up over his break up with Sam, Miguel eventually began dating a new Cobra Kai student named Tory Nichols.
After Hawk attacked and vandalized Miyagi-Do and took Mr. Miyagi's medal of honor, Miguel fought Hawk to recover it so he could give it back to the dojo. After defeating Hawk, Miguel took the medal and went to the LaRusso residence to give it back, only to be greeted by Robby. Miguel handed Robby the medal and told him to let Sam know he had given it back, though rather than do that Robby simply dropped the medal in the yard and did not inform Sam that Miguel had returned the medal.
Later though, Miguel and Sam were able to make amends a party hosted by Moon after Aisha told Sam that Miguel had in fact returned the medal. Sam went to apologize to Miguel for not realizing he was the one who returned the medal and the two ended up kissing, which was secretly seen by Tory.
On the first day of school, Tory went to attack Sam for kissing Miguel. Miguel raced to get to the confrontation to stop her and came in just as Robby Keene had stepped in in an attempt to resolve the fight. However, assuming Robby was trying to harm Sam, Miguel tackled him to the ground. As the whole hallway erupted into fighting, Miguel fought Robby, who was angry at him for kissing Sam and believed he was taking advantage of her. The fight eventually led onto the second floor of the school where Miguel managed to defeat Robby and pin him down. Remembering a speech by Johnny to not confuse "mercy" with "honor", Miguel let Robby go and told him "I'm sorry". However, still bitter over Miguel kissing Sam, Robby attacked Miguel and knocked him over the railing, sending him plummeting to the ground below. The impact of the fall severely injured Miguel and sent him into a coma, necessitating him to be hospitalized.
In Season 3, he is in a coma after the fall at the end of Season 2. He eventually wakes up and his mother and grandmother are faced with medical bills they can hardly afford. His sensei, Johnny comes to visit him but he is angry at him and blames him for the state he is in, he eventually reconciles with him and works with him to get his legs moving again.
He has irregular methods of physical therapy such as standing out of his wheelchair to grab a swimsuit magazine, and setting a fire under his wheelchair. These methods are unsuccessful but he slowly develops his healing process by tapping his foot at a Dee Snider concert and walks with a harness. He eventually fully gets his legs moving and convinces Johnny to open up a new karate dojo called Eagle Fang. He gets back together with Samantha LaRusso and meets her father, Daniel.
At a house party, Cobra Kai attacks the Miyagi-Do's and he faces his former bully Kyler, a new Cobra Kai. With Kyler's improved fighting skills and Miguel still recovering from his injury, Kyler has the upper hand for nearly the entire fight but Miguel gets enough motivation to regain his kicking and knocks him out with 2 kicks and 1 flipping knockout punch. Now with LaRusso and Lawrence's dojos allied against John Kreese, he is a star student of both.
However, Johnny and Daniel's combined dojo begins with a rocky start by their different styles feuding with their beliefs. Miguel and Sam decide to try to persuade them to work together. Miguel is able to eventually persuade Johnny by comparing him and Daniel's relationship as Rocky and Apollo from Rocky III. The next day, the students of both Eagle Fang Karate and Miyagi-Do decide to work on building an Okinawan sparring deck, in which it impresses Johnny and Daniel and decide to work their flaws together.
With Miguel and Sam dating again, Daniel invites Miguel's family over to learn more about each other and their goals. Although the night goes well, Miguel spills wine onto Daniel when talking about his college dream. Miguel and the other students of Eagle Fang work with LaRusso on new skills by trying to grab a koi fish from the dojo pond, however, no one is successful in doing so. When leaving, Hawk asks Miguel if he wants to practice, but Miguel says that his mom has to pick him up. Carmen ends up having car trouble and when Daniel hears about it, offers to take care of the car. Daniel drives Miguel to LaRusso Automotive so the two can work on it together.
This in turn, begins to bond Miguel and Daniel. The next day, Miguel comes up with an idea to catch the koi fish by going into the pond and surrounding them. This allows Miguel to be the first one to catch a koi receiving him a Miyagi-Do headband. While this happens, Johnny sees and he becomes jealous of their relationship. After practice, Miguel and Daniel work on Carmen's car again and Miguel learns of the history on Miyagi-Do and Daniel's career. Eventually, Daniel and Miguel finish his mom's car and Daniel tells Miguel to go drop him off at a birthday party. Miguel, who doesn't have a license, obliges and Daniel teaches him. The two bond over music and when Miguel runs a yellow light, Daniel tells him not to do so because it's dangerous. At the next light, Miguel stops, and the two smile.
During school, Miguel and Sam tell Hawk and Demetri that Johnny and Daniel are going to have a rematch to their fight from 1984. Sam and Miguel referee but Johnny and Daniel draw. The two dojos separate and Miguel goes back with Johnny.
Miguel and the rest of Eagle Fang learn about new updates to the 2019 All Valley Karate Tournament and need to get a girl student. They first come up to try bring Sam a chance, but Johnny rejects the idea. Miguel and Johnny then go to the school to try and find women fighters, but to no avail. After hours of trying, they find Piper who is Moon's ex-girlfriend, and ask her to join. She agrees and later when class starts, she doesn't show up. They learn that Piper joined Cobra Kai instead and need to find a new girl student. Bert talks about a girl named Devon and Johnny was able to persuade her to be their female champion.
Johnny goes to pick Miguel up for class and finds out about Carmen and Johnny's relationship. He is fine with their relationship but it begins to impact Miguel's training since Johnny doesn't want to hurt him. This upsets Miguel and he then confronts the two at family dinner. The next day, Johnny pulls Miguel out of school to talk in which Miguel still wants things to be the same. Johnny understands and when Sam shows up, Johnny teaches Sam and Miguel the flying tornado kick.
Prom night is here and Miguel and his family go to pick up Sam at the LaRusso's house. They take family photos and then make their way to the school. Sam and Miguel decide to not talk about Karate and have the night to themselves but when Robby and Tory show up together, it distracts them. A fight breaks out and Miguel, Sam and Tory all fall into the pool. That night, Miguel finds a drunken Johnny and helps him to bed. Johnny reveals that he loves him but calls him Robby, saddening him.
During the All Valley Tournament, Miguel shows off his offensive skills during the skills division but Eagle Fang end up falling into sixth place. After winning all his one-on-one matches, he faces Hawk, now going by Eli, in the semifinals. When Miguel is about to deliver a kick on a knocked down Eli, he ends up pulling a muscle in his back and collapses. Due to this injury, Miguel decides to not return to the fight. Before Sam's final match, the two reconcile and kiss. Miguel then leaves to go on a bus to Mexico City to find his biological father.
