Cody sometimes believes Zack doesn't care about the things he does, but this is disproven when Zack went to see his brother's speech instead of going to a Black Eyed Peas concert with his "friend" Theo. Zack does not have as much knowledge but has as much common sense as his brother. Zack also has no stage fright unlike Cody as seen in The Suite Life Goes Hollywood. Zack also can usually be found eating food, like chocolate, more often so than Cody, as evident in the episode Health & Fitness where Zack attempts to stop eating too much candy, possibly because Dylan has noted that he is the heavier of the twins. Most of the time he receives no retaliation for these actions although he seems to be intimidated by Cody when Cody stands up to him.

Zack is also known to put Cody down a lot, though he is quick to stand up for him when other people do it. Also in the On Deck episode " Shipnotized" Zack stands up for Cody after Harvard's dean of admissions makes him cry, telling him he'd be lucky to get into clown college. He is the charming, cool, funny, and greedy twin, but can also have a soft spot, and caring spot, for example in the episode: Election the two brothers run for president, and Zack almost beats him unfairly, but then helps Cody win. He also is the lazier of the two, often bossing Cody around. Zack also frequently gets into trouble sometimes along with Cody. And when he had to leave Carey on the Sea School Cruise, he proved he will miss his mom and doesn't want her to go. In The Ghost of Suite 613 when he got scared, he ran to his mom. He makes fun of his brother often, for many things (being smart, a germaphobe, etc.) and although he makes fun of his brother for crying and running home to their mom, it is shown that at times he can be a momma's boy. He takes after his father in many ways.He is also a good friend of London Tipton. He wants to be like his dad, Kurt, who is a rock star. Zack usually picks on Cody, but becomes very protective of his brother when other people do it. Zack has an obsession with women, and has always had a crush on Maddie Fitzpatrick, who works at the candy counter.
