Murphy's Law. Boom!

— Melissa Chase

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: for instance, she is prone to forgetting her personal belongings, such as her student discount card ("The Undergrounders") or her math book ("The Math Book").

Melissa was the first person brave enough to befriend Milo and is fiercely loyal and supportive of him. Even though Milo says that he doesn't think anyone would call him "tough", she does in front of Bradley and his friends ("Going the Extra Milo").

She's calm and controlled and loves when Murphy's Law shakes things up. She seems to enjoy betting on the results of Murphy's Law, and she often wins. She made a bet with Bradley and everyone who was interested that Milo and Zack would reach school on time. She won and replaced Milo's and Zack's destroyed lunches with the winnings. ("Going the Extra Milo") On another occasion, she bet Zack that Milo and his father being in the same place would increase the danger and won a dollar from him ("Worked Day").

She says that a tremendous portion of her self-esteem depends on her school grades. She also doesn't like egg puns ("Sunny Side Up"). She wants to become a 'journalist/queen of the Universe'. ("Worked Day")

Physical Appearance

Melissa is a slender girl with light skin and wavy, shoulder-length, ginger hair. Her blue eyes have visible pupils, and she's usually seen wearing a smug expression. Having caught a pop-fly to the face, her two front teeth are fake, though they cannot be differentiated from her other teeth.

She wears a white, elbow-length jacket with an upturned collar over a black shirt. The pink of her skirt matches that of her sneakers, which extend nearly as high as her socks.

When swimming, she wears a black one-piece swimsuit with two stripes across the waist, one pink and one white.

Richard Chase

ChristmasPeril (524)

Richard is Melissa's father. While the two of them are close, she tends to get annoyed when he expresses his disdain for Milo on a number of occasions. Melissa is not afraid to scold him when he's being rude. In spite of his frustration, she was able to convince him to let Milo ride in the firetruck after pointing out how much it meant to him.

She said exactly what he was about to say before he said it when repeating his driving mantra, implying he'd been narrating driving rules to her for some time. When Richard came to her school's parent-teacher meeting, she bragged about her grades, exchanging banter with her father after he reminded her to play it safe with his parental expectations.


Milo Murphy

Main article: Melissa and Milo's Relationship

Melissa and Milo are best friends who have known each other for years. She remained his closest friend for most of his life before Zack joined their group. Melissa has complete faith in Milo's ability to get himself and his friends through any situation Murphy's Law throws at them and by extension, is one of the only people in his life to hang out with him free of fear. She always stands up for him when he needs it and gives him encouragement anytime he begins doubting himself.

Zack Underwood

Main article: Zack and Melissa's Relationship

Having met through Milo when Zack first came to their school, the two are close friends. While Melissa has had years of experience with Murphy's Law and is, by nature, brave and fearless, Zack tends to be more nervous and realistic when things go wrong. She often encourages him to relax and see the fun in their adventures.


Bradley Nicholson

Bradley shows an interest in Melissa, often trying to spend time with her away from the danger surrounding Milo. While she is open to his attempts at friendship, Melissa would prefer to hang out with Milo, much to Bradley's disdain. She was quick to make a bet with him over whether Milo would make it to school on time.

Amanda Lopez

"You're a calm blue ocean."

Amanda and Melissa are on friendly terms with each other. Melissa is aware of Milo's interest in Amanda and has gone out of her way to keep things going relatively smooth when they hang out. She does her best to calm Amanda down when things get out of hand, using relaxation techniques in an attempt to make her feel better. When Melissa forgot her student ID, Amanda used her own so that she wouldn't lose her student discount.

She's used Amanda's obsession with order against her, but Amanda calls her out when she does so. This can be seen when she tricks Amanda into agreeing to go to Milo's party by claiming that cohesive color schemes didn't matter.

Chad Van Coff


Melissa is often annoyed by Chad's antics and tends to scold him for strange behaviors, such as rising up from behind her desk and constantly claiming that Mr. Drako is a vampire. He seems to like her and ran to her for help when he thought the school was being invaded by vampire hunters. In spite of her complaints, she helped him defend their teacher while continuing to claim that he wasn't a vampire.

She forced him to give her five dollars during the Athledecamathalon competition and then refused to give it back when she saw how easily he'd given up.


Martin and Brigette Murphy

Melissa is on friendly terms with Milo's parents and seems to have known them for a long time. She enjoys spending time with them alongside Milo and Zack, having gone on a skiing trip with Martin.

Sara Murphy

Melissa is on good terms with Milo's sister and enjoys hanging out with her. Sara was thrilled to introduce her to Doctor Zone, although, like Zack, Melissa ended up more tired and confused then excited about the show. They've ended up on a number of adventures together when things get out of hand. When Milo goes missing, Melissa and Zack go to Sara for help and end up saving the world from Pistachion invasion together.

Elliot Decker

Melissa is generally neutral towards Elliot in spite of his disdain for Milo, but she is not afraid to argue with him when he gets out of hand. She's used his obsession with safety to her advantage on a number of occasions.

Balthazar Cavendish and Vinnie Dakota

While Melissa doesn't know Cavendish and Dakota very well, she is on friendly terms with them. She often seems apprehensive of their strange antics. Originally, she confronted them after Chad convinced her that the duo were vampire hunters, and she'd agreed with his assumption that they were there to hurt Mr. Drako. This impression didn't last long, and Milo officially introduced them to her, Zack, and Sara in the episode Missing Milo.


Melissa is on good terms with Scott. They'd originally met when Melissa ended up underground with Milo and Zack, and again after she'd been pursued underground with Zack by Brick and Savannah. Scott helped her escape the agents and led her back up to the city.

“Dad! It's just Murphy's law; he can't help it. Besides, he just... A pound of sugar? Really?... Besides, he also just saved us by thinking on his feet. ”

“I started collecting this, thinking maybe I could figure it out, you know? Find a cure for Murphy's law. But then I realized Milo wouldn't want that. But, for some reason, I kept collecting info, so at least, maybe, I could rein it in or explain it or monetize it.”
