You probably shouldn't have done that!
— Jack's catchphrase.
You know... because of you, all of our lives are a lot better.

Sensei Jack Brewer is the main protagonist of teen sitcom Kickin' It. He was born on October 8, 1997 and is the newest member of The Wasabi Warriors along with Kim who joins after, and is often seen as having the hero complex of the group. He is a dedicated skateboarder who learned martial arts from his grandfather, Bobby Wasabi's former teacher and sensei. As a kid, he moved around a lot, but is able to adjust quickly, and he is able to make friends very easily. Jerry, Eddie, and Milton invited him to sit with them in school even before he takes out four Black Dragons, who happen to be bullies. He lives by The Wasabi Code. Jack has the highest rank in the dojo, being a 2nd degree black belt. He is also a heartthrob as seen by the many girls that fall for him. He is the unspoken leader of the Wasabi Warriors. He is Kim's boyfriend and main love interest.



Jack often has to inspire people to do their best, and often helps the group solve their problems. He is convinced Kim has a crush on him (which she does) and he has a crush on her in return.

He was first seen in the dojo when he jumped through the wall to try to not be caught by the mall cops. He has a fear of clowns ever since his fifth birthday. He's loyal to his friends and will go to extreme lengths to protect them. For example, he saved the dojo from getting destroyed with a wrecking ball in Dojo Day Afternoon by stopping the wrecking ball. In the episode Wax on, Wax off, it is shown he's the best at sparring (A badge on his Gi which says "Best Sparring"). During My Left Foot, it is seen that Jack is not very good at football, and can barely even throw the ball. In Eddie Cries Uncle, it is revealed Jack is part of an intramural basketball team. When he was younger, Jack was taught Karate by his grandfather, who trained Bobby Wasabi for all his movies, with his cousin Kai (Kickin' It in China), until his family were ashamed of Kai.

As of Spyfall, he now works at the Bobby Wasabi Dojo as an instructor.  He was promoted to assistant sensei in The New Girl.

After Kickin’ It In The Office, he is now a Sensei.


Jack is extremely strong, which allows him to do several things the other members of the dojo cannot. Jack is not only gifted at karate, but he is a 2nd degree black belt and is able to instruct students of the dojo just as well as Rudy. He is also a very talented skateboarder, as seen in Badge of Honor and Skate Rat. He likes playing by his own rules and sometimes gets upset when others enforce rules upon him. Jack is an extremely nice guy, and goes to great lengths to help out his friends. Jack is cool, yet sensible, and he knows what decisions to make in tough situations. Because of his personality, many girls are attracted to him.


Jack is described as a tall, muscular, and very good looking teenage boy. He has a pretty boy face and great hair, which is referred to several times on the show. He also has a mole on his face. It was mentioned that he was voted having best hair in eighth and ninth grade. Because of his appearance, many girls are attracted to him.


  • Kim CrawfordGirlfriend - Kim was the first person from the gang Jack had met in Seaford High School. He caught her falling apple with his foot. In the episode Wasabi Warriors, Kim manages to appear with Jack quite a lot, and, from this, became a theory of the two liking each other. When they first met, Kim was training in the Black Dragon Dojo, but Jack was brought into the Bobby Wasabi Dojo. Kim and Jack were put together for the vertical peg kick part of the tournament. Frank from the Black Dragons had just hurt Jack's leg, but after Kim saw Jack successfully kick the peg by launching off his hands, she decided she wanted to train with him and the Wasabi Warriors.

    From then on, fans had the idea that the two were to get together and go out with the cute couple name, "Kick". In the episode "Road to Wasabi", Kim and Jack were together in almost all of the scenes. Jack even took Kim into his arms, grabbing her waist and spun her around to kick the ninjas behind him. In the episode "Ricky Weaver", which helped fans understand the relationship between them, Jack tries to protect Kim from Ricky Weaver, who planned to break her heart. He also teases Kim by imitating her snort. At the end of the episode, Jack asks Kim to go out to eat, and she says yes while biting her bottom lip. This tends to be an enticing way of implying your thought, "I wonder if he's going to kiss me." Also, in Kung Fu Cop, Jack constantly flirted with Kim in his dream and after he woke up he said everybody had bad hair except Kim, because she looked pretty. She then said thanks and said her mood ring turned red, just like it did in the dream when he flirted with her. A red mood ring often means excited or happy with what is about to happen. That scene suggests that their relationship may lead to becoming more than just friends. Overall, they have a good, stable relationship; to the point where they can be more than friends, and it is shown in many episodes that he likes her and vice versa. Also, in Karate Games, Jack and Kim are filming a movie together and they have to kiss, but they didn't kiss. Then they pulled away when the director, they had previously fought, yelled "CUT!!!". Jack asked Kim on a date in Kickin' It On Our Own. They both danced together in Spyfall. They were both very close during the dance. In Two Dates and a Funeral, Jack asks Albert to bet on Kim so that they can go on a date. Kim makes Jack a bracelet, and Jack gets Kim a corsage. In that episode, Kim and Jack finally start dating, and officially, are a couple. In the fourth season Jack and Kim are still dating even though Kim is in Japan. Kim is seen in three episodes in that season. In Seaford Hustle Kim and Jack were supposed to have a phone conversation each other but Jerry ignores her calls. So, to make up for it, Jerry flies Kim out to visit. Kim and Jack and ecstatic to see each other and share a kiss at the end of the episode.
  • Rudy - Sensei-Student, Friends - Sensei Rudy owns one of the branches of the Bobby Wasabi Dojo. He meets Jack when Jack does a flying sidekick and crashes through his wall. He offers Jack a spot in his dojo

    so that he can win two belts to keep his dojo. At first he and Jack get off to a bad start after he lies to Jack about his punishment for skateboarding in the mall and for destroying the dojo wall. Jack soon learns though that he did it for the dojo and Jack soon forgives him. Later on in the series they change from sensei-to-student phase to a friendship phase. Rudy tries to help the kids in any situation. In Eddie Cries Uncle , Rudy tries to help the kids earn money. In We are Family and Breaking Board, he helps Eddie as well.

After Jack leaves, Milton says aloud that he was sad he learned Jack's name and that he was going to miss him. Jack is very loyal to Milton and helps him whenever he has a problem. In Fat Chance, Jack helps prove to Milton that he is a hero after he helps out a former sumo wrestler. In Swords and Magic, Jack also helps Milton fight a group of boys for a game that is played in the park every year. In Clash of the Titans, Jack (and Kim) help
