|“||Oh, that's not a curse! That's just inexperienced casting.||”|
— Marcus after Murphy's Law ruins his hat on a fishing trip
He is voiced by Phil LaMarr.
He seems to be easy going and calm under pressure, as shown during his and Zack's fishing trip with Martin and Milo. Initially, he was skeptical of the existence of Murphy's Law, attributing the mishaps to things like 'inexperienced casting'. But once things really started going wrong he was quick to help.
He loves to scare his son and has been doing so all of Zack's life.
Marcus has a round face, brown eyes, and dark skin. He has short, dark brown hair that is receding and a goatee.
He wears a blue short-sleeved shirt with a darker blue color on the ends of the sleeves and the collar. His knee-length shorts are beige, and he wears a pair of brown sandals that have a thick strap across each foot.
He was shown in a flashback with his son and his wife on a boating trip where Zack got scared by a fish that landed on their boat.
In "Time Out", Marcus, Zack, Milo, and Milo's dad went on a fishing trip on Murphy's Yaw. At first, he doesn't believe in Murphy's Law, but throughout the day he eventually believes in the Murphy family curse.
In "Perchance to Sleepwalk", he and his wife were at a spa while their son and his friends went camping.
In "Milo Murphy's Halloween Scream-A-Torium!", his son revealed that he scared Zack every Halloween, much to his amusement. His most recent attempt had him dressed as a fish, his son's worst fear.
In "Cast Party", he drops Zack off at school.

“Son, you shouldn't get out of the boat.”
“Every time he comes home with a rip in his jeans or covered in "Pterodactyl blood," he credits it to some Murphy family curse.”
“Yeah, okay. Murphy's law, real thing.”
“I used to love getting dressed up, and my dad used to love scaring me. And man, was my dad good at it! Every year it was something new, as far back as I can remember. He was always scaring me... And it was awesome!”
