Kyler Park (Cobra Kai)

Kyler is a high school bully in the series Cobra Kai. He constantly targeted Miguel Diaz, Eli Moskowitz, and Demitri until the former learned karate and stood up for himself. He would later join Cobra Kai under the formerly retired John Kreese, as his wrestling skills make him an above-average student.

Why He Deserves No Mercy

 * 1) The main problem is that Kyler is a spoiled rich brat who comes across as rude, immature, reckless, and egotistical who only cares about being the center of attention around high school no matter what it takes to beat and harrass them (including his victim, Miguel Diaz), making him an unsympathetic antagonist, a laughing hooligan, and a one-dimensional Mean Popular Boy.
 * 2) 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 in 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 Diaz at the mini-mall which left Daniel puzzled and makes him a karma houdini for that.
 * 3) He has no reason so exist, but is meant to show what Johnny Lawrence would have become if John Kreese pressures to do karate mercilessly a lot.
 * 4) He is indeed unapologetic and does not after Miguel fight him back at lunch.
 * 5) He is portrayed like a lifeless stereotypical teenager who shows no respect but just to make others as losers.
 * 6) 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...
 * 7) *Spilling Pepto Bismol all over Miguel.
 * 8) *Throwing Demitri's backpack in the trash (resulting in it being covered in yogurt).
 * 9) *Making fun of Miguel of how much he is a sore loser at the library.
 * 10) *Beating up Miguel during Halloween night.
 * 11) *Spreading lies about Samantha to tarnish her reputation.
 * 12) His gesture to Miguel while with Samantha in the School Cafeteria may come across as cringe-worthy.
 * 13) He only dated Samantha LaRusso for sexual desires. Examples include...
 * 14) Attempting to have sex at the Halloween Party possibly without Sam's consent.
 * 15) Attempting to GROPE her at the movie theater.
 * 16) *Samantha instantly noticed and fended off his assault.
 * 17) Despite being unlikeable, he gets more screentime in season 1 and 3.
 * 18) We barely even know much about Kyler or his motivations.
 * 19) His bullying antics gets old very quickly and will get you on your last nerve.
 * 20) His actor, Joe Seo does a weak job portraying him until he would later improved somehow in season 3.
 * 21) He barely gets any character development whatsoever.

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.
 * 2) His fighting skills have improved in Season 3 thanks to John Kreese's training.
 * 3) His characterization is slightly improved in Season 3 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.

Trivia

 * It's implied that his bullying behavior may be due to the insecurities of his parents who have high standards for him. This was mentioned that his father was just some selfish, greedy rich man who would be disrespectful to his son by defecating his mouth if he doesn't pass trigonometry, indicating that Kyler's parents were selfless people who wanted their son to be a perfectionist and rebel against their authority.
