— Melissa referring to Zack

Melissa Chase is one of the main characters in Milo Murphy's Law, voiced by Sabrina Carpenter. She is best friends with Milo Murphy and Zack Underwood.


Confident and self-assured, Melissa is smart, if sometimes a little scattered. She was the first person brave enough to befriend Milo and is fiercely loyal and supportive of him. She's calm and controlled and loves when Murphy's Law shakes things up. Even though Milo says that he doesn't think anyone would call him "tough", she refers to him as such in front of Bradley and his friends (Going the Extra Milo). She says that a tremendous portion of her self-esteem depends on her school grades (Sunny Side Up). From the same episode, she doesn't like egg puns. She wants to become a journalist or Queen of the universe (Worked Day). She has a tendency to lose her personal belongings, such as her student discount card (The Undergrounders) or her math book (The Math Book). She seems to enjoy betting on the results of Murphy's Law, which she often wins. In Going the Extra Milo, she bet Bradley and everyone who was interested Milo and Zack would reach school on time, getting their lunches for them and in Worked Day, she bet Zack that Milo and his father being in the same place would increase the danger, winning a dollar from him.

Melissa has been very good friends with him for years. She has complete faith that although Milo gets into accidents, he will always get where he needs to be on time.

(In Sunny Side Up, she sees that their classmates hide to make sure to not be in Milo's team, she call them "cowards"). She doesn't seem to mind Milo's misfortune, as shown in Party of Peril where she is the only one not behind protective glass as Milo prepares to blow the candles on his birthday cake.

  • In Party of Peril, Mort asks Melissa if her dad was a paramedic which she answers "yes", but in Worked Day we see him working as a fireman. This could possibly be due to real life firefighters being trained paramedics as first-responders on the scenes.
