Zachary "Zack" Martin (Dylan Sprouse), along with his brother Cody Martin, is one of the two main protagonists in The Suite Life series. He is typically the unstudious, outgoing, rebellious,self- centered and often the lazy twin, who is often seen wearing skater clothes. Academically, he is a straight "D" student, though he shows a great interest for wood shop—the class in which he is the best student.
Zack is good friends with Marcus, Woody, London, Maddie, Barbara, Jessica and Janice, Bailey, and Bob. He was dating Maya Bennett, a girl whom he met working as a waitress at the Juice Bar on the S.S. Tipton, but they broke up in the series finale, "Graduation on Deck".
