Kyler is first seen with Brucks and two other of his friends trying to buy beer from a mini-mart. When Miguel unintentionally tells the store clerk that Kyler and his friends aren't old enough to buy it, Kyler and his gang begin bullying Miguel, taking the Pepto Bismal he bought for his grandma and dumping it on his head, as well as nicknaming him "rhea" (short for "diarrhea") for buying it.
After shoving Miguel up against Johnny Lawrence's car, Johnny decides to step in, telling them to back off. When Kyler makes fun of Johnny, Johnny fights off the gang, using his karate moves to easily beat all of them down. However, the fight is soon broken up when the police arrive and arrest Johnny.
Kyler later begins dating Sam LaRusso and ends up being invited to have dinner with her family by her father, Daniel LaRusso. At the dinner, Kyler tells Daniel about what happened at the mini-mart after Daniel asks him about his black eye, but spins it to make Johnny seem like the aggressor, leading Daniel to go confront Johnny about it at the latter's Cobra Kai dojo.
Sam eventually breaks up with Kyler when she discovers he has been bullying Miguel. To get back at her, Kyler spreads rumors that she had given him a blowjob after the two went to see a movie. After Kyler makes fun of Sam at lunch, Miguel gets up to go and confront him. Kyler and his gang challenge Miguel to another fight, but with the training he received from Johnny at the Cobra Kai dojo, Miguel is able to beat down Kyler and his three cronies in front of the entire cafeteria.
Kyler later appears again accompanying Yasmine and her friends when they go down to a canyon to set up for her birthday, only to discover that Cobra Kai had gotten there first and thrown a party. Yasmine tells Kyler to go down and force the kids to leave, but after sighting Miguel and Hawk, Kyler gets scared and suggests they go somewhere else.
