Nick Apostolides is an American actor and voice artist recognized for his portrayal of the iconic character Leon S. Kennedy in the Resident Evil franchise. Born in Boston, Massachusetts, he developed a dramatic acting style rooted in method techniques and combined this with a background in physical performance and stunts. Before his prominent work in voice-over and motion capture, Apostolides accumulated experience in over one hundred commercials and earned a regional Emmy Award nomination for hosting the history program American Ruins.

His entry into the world of video games and animation was fueled by a personal passion for the medium. He began contributing to major interactive franchises, with early credits including roles in the Life is Strange series. He voiced Frank Bowers in Life is Strange: Before the Storm and later took on the role of Charles Eriksen in The Awesome Adventures of Captain Spirit and Life is Strange 2. This period established him as a versatile performer in narrative-driven games.

Apostolides's defining role arrived in 2019 when he was cast as Leon S. Kennedy in Capcom's critically acclaimed Resident Evil 2 remake. He provided both the voice and full performance capture for the character, a task that drew upon his physicality and stunt experience. His performance was well-received, earning him the IGN Horror Fest Award for Best Actor in a Horror Game. This success cemented his association with the character, leading him to reprise the role in the 2021 Netflix original CGI anime series Resident Evil: Infinite Darkness. In the series, he once again performed the voice and motion capture for Leon, a government agent investigating a zombie outbreak at the White House. He continued his work in the franchise with the release of the Resident Evil 4 remake in 2023. Beyond this flagship series, his voice can be heard in other major properties, including Call of Duty, Medal of Honor, Apex Legends, and Warframe.
