Zack is the new kid in town and the voice of reason when things get out of hand. While the rest of the town is used to Milo, Zack is trying to enjoy the adventure of being Milo's best friend without getting destroyed. He wants to follow Milo because he wants a change from common life. In fact, he accepts going to school with Milo because his adventures are unique. (Going the Extra Milo)
He also wants to be safe enough though. In the episode Sunny Side Up, he has no problems on doing a science project with Milo, even knowing that it's extremely hard, but when they made it he didn't let Milo get near to make the project safe.
Maybe because he's new, he seems to not be fully aware of what Murphy's law can cause. He often says that things couldn't go worse, or he thinks that is some case, nothing wrong can happen. Zack is also fairly self-conscious about previously being part of The Lumberzacks, at times trying to conceal the fact from his friends while at others actually hoping to be recognized for the role.
Zack has brown skin and black hair. He wears a short-sleeved yellow shirt with a white long-sleeved shirt underneath, gray pants, and blue and white sneakers.
Prior to moving to Danville - or at least the area of it where he currently resides - Zack was the leader of the boy band The Lumberzacks, who gained some popularity from their song Chop Away at My Heart. Zack later left the band and came to be embarrassed by the fact of his membership in it, as described in Secrets and Pies. In Murphy's Lard it is revealed that, due to an incident on a boat ride with his parents, Zack has developed a crippling phobia of fish.
Zack first meets Milo in Going the Extra Milo when he is on his way to attend his first day of school, with the pair meeting at the bus stop. After seeing several other students - including Bradley Nicholson, Chad, and Melissa Chase - purposefully keep their distance from Milo, Zack questions the reasoning behind it and initially wonders if Milo is supposed to be a "tough guy." He soon learns that Milo is, in fact, the subject of ongoing mishaps due to Murphy's law, which Zack begins to experience as the two are forced to flee from a section of concrete pipe that has fallen off of a truck. The two are able to escape due to Milo's quick-thinking but are forced to chase the bus.
Zack and Milo endure several other calamities - an oil spill that catches fire, a pack of wolves, and a beehive that becomes stuck on the head of one of those wolves - as they continue their pursuit of their school bus. After they end up in the city sewers, Zack announces his intentions to go his own way, only to gain a new perspective on the unusual situation from Milo, who notes how much more exciting their morning has been than that of their classmates. The two are then caught in a flood caused by the absence of the pipe they escaped from previously, washed into a river, and then thrown off a cliff only to land on top of a flying saucer. However, as they are about to be apparently dissected by the aliens, Zack informs the extraterrestrials that they may become late for school, and the aliens then teleport the pair to their first-period classroom just in time. The pair is elated but then realize that their lunches have been destroyed, only to discover that Melissa has taken care of the situation due to starting a betting pool in which the different students on the bus bet food on whether or not Zack and Milo would make it to school on time.
In Sunny Side Up Zack teams up with Milo and Melissa for a science project involving creating a device that will enable an egg to survive a long fall intact. They are eventually successful, though only after destroying an inordinate number of eggs, and Zack and Melissa take their last remaining egg and the device home with them. Zack then has a nightmare about the device being destroyed, but wakes up to find that it wasn't real; unfortunately, the egg is smashed before they can take part in the experiment. Fortunately, an egg Milo had put in his pocket earlier turns out to be intact, allowing them to test their device in front of the class. The device and the egg end up going through an insane amount of punishment after being hit by a delivery truck, but ultimately the egg lands safely-only to be eaten by Diogee after Zack's group is graded with an A.

When the two hit upon the idea that Time Ape is actually Doctor Zone's brother, the fans are disgusted, but Zack and Melissa are later proven right.
In The Note, Zack and his friends attempt to recover the signature page from a bulk doctor's note for Milo, as otherwise he will have several unexcused absences and have to repeat seventh grade.
