This article is about the character from the 2019 animated series. You may be looking for the character from the 1994 animated series.

Zack is a professional thief who works with his older sister Ivy and Carmen Sandiego.

Zack and Ivy are originally from Boston, Massachusetts, a historic city in the US.


Zack is the buffoon of the gang. He is generally noisy, idiotic, infantile, easily distracted, often repellent and less cautious than his sister, as he often thinks with his stomach, and as such is often reduced to following either Carmen or Ivy's instructions. On the other hand, despite being very goofy and having a looser behavior, he is surprisingly good at improvising lies, almost in a pathological manner; even if he doesn't know what he's talking about. His confidence can sometimes convince the people he's lying to, such as when he lied to Dash Haber about being a Duke and when he convinced El Topo that "the dingoes [were] going crazy".

Like his sister, he has a thick Boston accent. He can be trained to speak in proper diction when the need calls for it—especially when he needs to go undercover. The accent, however, will waver from time to time.

Zack has a large appetite and will eat any food, except for fish. He also hates it when people call Boston "Beantown".

Like everyone on Carmen's team, he uses his thieving skills for good. He also acts as a getaway driver for Carmen when she escapes her capers, being a highly skilled driver of both cars and boats (and once a helicopter). Zack is a big fan of action movies. When Carmen buys Zack a car from one of his favorite movies using money from V.I.L.E., Zack ponders whether the car is capable of the feats in the movie.


Zack has red hair, although lighter than his sister's. He has light cornflower blue eyes and freckles sprinkled across his face. Zack is shown to be decently tall. He wears a white and red baseball jersey, a black long-sleeve undershirt, dark blue jeans, and grey sneakers.



Zack often serves as a getaway driver for Carmen's Team, being able to drive almost any vehicle, from trucks, boats and the Al Sabaq 9000.


Zack has also shown to be a skilled actor, being able to replicate other accents relatively consistently.


Boston Championships

Before meeting Carmen, Zack and his sister Ivy were race car drivers. They borrowed money from a man named Sharkhead Eddie to drive. Ivy built the car they used and Zack drove it. They moved from amateur tracks to the professional league, where Zack met Trey Sterling, his rival. Trey taunted Zack about his car and Zack wrecked it in a reckless attempt to beat Trey. Zack and Ivy asked Eddie for more money to repair the car, but he refused, instead telling them to rob a store that was most likely used as a drop off point for the mob to pay him back.

Meeting Carmen Sandiego

That was where they met Carmen, and the store was actually used as a drop off point by V.I.L.E instead of the mob. They latched onto Carmen because they knew that she would lead them to the money. By the end of that night, however, they helped Carmen defeat V.I.L.E but realized that they were unable to use any of the money they stole. Zack and Ivy asked Carmen if they could tag along with her, and they have been with her ever since.

  • This version of Zack is a major departure from his other counterparts. In the original version, Zack and his sister, Ivy, work for the ACME Detective Agency whose main goal is to apprehend Carmen. In this version, Zack, while still heroic, is a professional thief who is actually aiding Carmen, who in this version is attempting to dismantle V.I.L.E.
  • Zack is always hungry in this incarnation, and Ivy often has to take charge in situations.
  • His favorite movie series is Rouge Vendetta.
  • Zack doesn't like fish, or the sea.
  • In The Need for Speed Caper, Zack tells Trey Sterling that he is a duke, and Ivy a rocket scientist. These are references to the earlier episodes "The Duke of Vermeer Caper" and "The Opera in the Outback Caper" respectively.
