Kyler Park (Cobra Kai)

Kyler Park is a recurring antagonist and the high school bully in the series Cobra Kai. He constantly targeted Miguel Diaz, Eli Moskowitz, and Demitri whom he sees them as unpopular losers and weaklings until the former learned karate and stood up for himself. He would later join Cobra Kai under the formerly retired John Kreese in the second season and his friend, Terry Silver in the fourth season, as his wrestling skills make him an above-average student.

Why He Intentionally Deserves No Mercy
Note: This characterization was likely done on purpose.
 * 1) The main problem is that Kyler is a spoiled rich brat who comes across as rude, immature, reckless, cruel, and egotistical who only cares about being the center of attention around high school no matter what it takes including beat up and harass unpopular students (like his favorite target, Miguel Diaz), making him an unsympathetic antagonist, a laughing hooligan, and a one-dimensional Mean Popular Boy.
 * 2) *He is also one of the worst characters in this show as he's done horrible things to Miguel and others.
 * 3) **His motivation over bullying people may be due to the insecurities of his parents who have high standards for him. This was even mentioned that his father was a strict, yet disrespectful/abusive parent towards his son such as defecating his mouth if he doesn't pass other exams including trigonometry, indicating that Kyler's parents were selfless people who wanted their son to be a perfectionist and rebel against their authority. That is a possible reasoning why Kyler sees his bullying victims as weak, unpopular losers.
 * 4) ***The fact is, Asian parents are known to be strict and demanding considering their children are insecure to forced into performing well in school in a manner of perfection.
 * 5) He always tries to play the victim - After he and his gang fight against former Cobra Kai student, Johnny Lawrence while harrassing and beating up his classmate, Miguel Diaz for spilling Pepto Bismol outside from the mini mall, he tells Daniel LaRusso that he and his friends were attacked from Johnny and mistaking him for being "some homeless-looking guy". Also, he even hides of his harrassment of Miguel which left Daniel puzzled and makes him a karma houdini for that.
 * 6) He is indeed unapologetic and does not after Miguel fight him back at lunch.
 * 7) He is portrayed like a lifeless stereotypical teenager who shows no respect but just to make others as losers.
 * 8) Since his role in the first season, his “fighting skills” used to consist of yanking people’s hair, pushing, and just put things on to someone.
 * 9) His dialogue is incredibly painful and would always say “loser” or constantly swearing.
 * 10) Similar to Peter Griffin (Family Guy) and Eugene Krabs (Spongebob Squarepants), he constantly bullies people he considers to be weak and even being sore losers only for his own gain and satisfaction. Examples include...
 * 11) *Spilling Pepto Bismol all over Miguel.
 * 12) *Throwing Demitri's backpack in the trash (resulting in it being covered in yogurt).
 * 13) *Making fun of Miguel of how much he is a sore loser at the library.
 * 14) *Beating up Miguel during Halloween night.
 * 15) *Spreading lies about Samantha to tarnish her reputation.
 * 16) *Helping Cobra Kai cut off Eli's mohawk.
 * 17) *Throwing Miguel to the pool to keep him out of trouble.
 * 18) His gesture to Miguel while with Samantha in the School Cafeteria may come across as cringe-worthy.
 * 19) He is sexist, only dating Samantha LaRusso for sexual desires. Examples include...
 * 20) Attempting to have sex at the Halloween Party possibly without Sam's consent.
 * 21) Attempting to GROPE her at the movie theater.
 * 22) *Samantha instantly noticed and fended off his assault.
 * 23) Despite being unlikeable, he gets more screentime in season 1, 3 and 4, while having absolutely no character development at all other being a mean-spirited jerk.
 * 24) Since being a bully, he comes off as rather bland to be cruel whenever he laughs, embarrassed and harassing people in their nerves.
 * 25) His evil smiling and smirking will get you on last nerve whenever he encounters Miguel or else.
 * 26) He never even learns his lesson whatsoever until season 5.
 * 27) His actor, Joe Seo does a weak job portraying him until he would later improved somehow in season 3-4.

Redeeming Qualities

 * 1) After being beaten by Miguel in the Cafeteria fight, he becomes scared of Miguel or any Cobra Kai student, showing that he is better off a coward on the inside for what he treated Miguel and he no longer torments every day at school.
 * 2) His fighting skills have improved in Season 3-4 thanks to John Kreese and Terry Silver's training.
 * 3) His characterization is slightly improved in Season 3-4 as he becomes more confident fighting opponents who are equally strong as him or stronger, like Miguel or Eli.
 * 4) His fight sequences with Miguel are enjoyable to watch even in the aformentioned Cafeteria fight and the LaRusso household.
 * 5) In Season 4, He gets his comeuppance again for helping Cobra Kai cut off Eli's mohawk. He is later beaten by Eli in the All Valley Tournament for that.

Trivia

 * In the fourth season, his last name is revealed to be Park.
