Zack Underwood

Zack Underwood is one of the main characters in Milo Murphy's Law, voiced by Mekai Curtis. He is the best friend of Milo Murphy and Melissa Chase.

Personality
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 fun. (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 often says that things couldn't go worse, or he thinks that is some case, nothing wrong can happen.

Physical Appearance
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.
