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

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

Zack is currently being 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 when playing his electric guitar in his room instead of doing his homework. His dad talks to Principal Mullins and she takes out Zack of Mr. Finn's class and moves him to another class. After Zack gets caught jumping out of the window, Mr. Kwan comes and talks with Zack on why he is acting rebellious and standing up to him. Zack says that Mr. Finn 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!
