Dude. I went right after you!
—Zack to Lawrence Dooley about going right after him on the water slide.

Zachary "Zack" Kwan is a main character on School of Rock. He is one of the electric guitar players of the School of Rock band, and a student at William B. Travis Prep School.

He is portrayed by Lance Lim.


Lance Lim ("Growing Up Fisher") as "Zack", a reserved child of overbearing parents, who comes out of his shell as the band's electric guitarist. He walks the line between fearing the consequences of breaking the rules and embracing the independence that Dewey encourages. Zack is a good friend to all, and with the confidence he gains from the band he makes the choice to become his own man instead of a "Yale man". For example, in We're Not Gonna Take It, Zack gets caught by his dad playing his electric guitar in his room instead of practicing classical guitar. His dad talks to Principal Mullins and takes Zack out of Mr. Finn's class and moved him to Mr. Fox's class. After Zack gets caught jumping out of the window to join Mr. Finn's class, Mr. Kwan comes and talks with Zack about his rebellious attitude and Zack stood up for himself for the first time. Zack says that Mr. Finn had a big influence on him and taught him to not be afraid to stand up for what you believe in.


Zack has some of the best guitar skills in school. He’s also got some of the strictest parents, which isn’t the best combination for a wannabe rock ’n’ roller. He’s often torn between following orders and breaking the rules but luckily, he’s great at talking his way out of trouble!
