Mary Mouser

Intro

Mary Mouser is an American actress known for playing Samantha LaRusso in Cobra Kai. Her work also includes the medical drama Body of Proof and the animated series Eloise. Those credits trace a career across voice performance, family stories and the action-driven continuation of The Karate Kid.

Career snapshot

Mouser worked on screen and in voice roles before joining Cobra Kai. As the title character in Eloise: The Animated Series, she performed through voice rather than physical presence. She later played Lacey Fleming in Body of Proof, appearing as the daughter of Dana Delany’s medical examiner Megan Hunt.

The entry point

In Cobra Kai, Samantha is the daughter of Daniel and Amanda LaRusso. The series places her within a younger generation whose relationships and rivalries develop alongside the returning adults. Her place in the LaRusso family connects her to the earlier films while giving the television story a separate set of adolescent experiences.

Screen identity and style

The part combines family scenes, friendships and martial-arts competition. Watching Samantha across the series means following changing loyalties and confidence as well as tournament results. Her character’s choices are often affected by events both inside and outside the dojo.

Collaborations and patterns

In a Netflix cast interview, Mouser recalled the welcome she received from Ralph Macchio when she joined the LaRusso screen family. Their father-and-daughter relationship provides one of the show’s links between generations. The convention photographs here show Mouser with fellow performers discussing the series in public.

Era reflection

Her other television credits include Karen Grant in Scandal. That role and Lacey Fleming offer viewing points outside Cobra Kai, while Eloise presents a different medium altogether. These formats provide context for an actor many viewers first encountered through one continuing streaming-series character.

Legacy and rediscovery

Begin with Cobra Kai’s early episodes to see Samantha’s family and friendships take shape, then compare Body of Proof and Eloise. The two gallery photographs were taken at Washington State Summer Con on June 22, 2025. They are distinct views from the same event; the portrait is cropped from the photograph of Mouser beside Tanner Buchanan.
