Zach is a supporting character in the film Sky High.
Zach wears fluorescent colors like white, yellow, and green. His style of dress is very casual and in most cases clashing (such as wearing white socks with his sandals and a white visor on his head).
Illumination: Zach can glow in the dark. There are times where he will simply clap his hands and start glowing or will be begin to glow when in a dark environment.
Zach is exuberant and confident in himself. He is loyal to his friends and tends to talk big to the bullies, often earning him a spot crammed in a locker. When he is assigned to the Sidekick class, he tries to persuade Coach Boomer to change his mind, thinking that the gym setting was not right for showing off his ability.
At times, he tries to impress Magenta by acting tough and nonchalant like she is.
In the end, he is recognized as a hero for assisting the other heroes in stopping Royal Pain's devious plan of creating a generation of supervillains.
