Zach

Zach is a minor character in The Amazing World of Gumball. He is the alter ego of Gumball, and he made his first appearance in "The Name."

Upon discovering that his real name is Zach, Gumball begins to act, and dress differently, and wishes to be called Zach. It is discovered that this alter ego is taking over Gumball by altering his memories, up to the point where Gumball doesn't remember what his nickname is or what he's done as "Zach." The Wattersons decide to make "Gumball" his legal name, before Zach takes over completely. Gumball soon defeats Zach, and he fades/disintegrates away.

Appearance
Zach wears purple sunglasses, and pops out his collar. He speaks in a deeper voice than Gumball, while usually raising his eyebrow at every moment. He also has a different personality than Gumball.

Personality
Zach is boastful, confident, arrogant, and, generally, full of himself, like the stereotypical jockjerk. Unlike Gumball, who recognizes his own failures, and lives with them, Zach refuses to acknowledge any of his shortcomings or losses, going so far as to alter the memories of his/Gumball's failures to turn them into victories. He also views Gumball as a loser.

He typically rides a purple skateboard around everywhere, and refers to himself in the third person while mentioning fake "cool" memories he's done with them at his school.

​Abilities
Zach is a memory jogger. Each time Zach claims a victory in Gumball's memories, Gumball slowly fades away. He uses all kinds of weapons, like a bazooka while attempting to blast Tobias, and a tennis racket to attack Carlton and Troy with multiple tennis balls.
