Kamar de los Reyes, a Puerto Rican actor best known for playing the police officer Antonio Vega in the soap opera “One Life to Live” and for voicing the villain Raul Menendez in the video game franchise “Call of Duty,” died on Sunday in Los Angeles. He was 56.

He died of cancer, according to Lisa Goldberg, the publicist for his wife, the actress Sherri Saum.

De los Reyes was born in San Juan, Puerto Rico, on Nov. 8, 1967, to a Cuban father, Walfredo de los Reyes, and a Puerto Rican mother, Matilde Pages. He described himself as coming “from a family of musicians”: His two brothers and father were acclaimed percussionists, and his grandfather was a famous trumpeter.

De los Reyes was raised in Las Vegas and, after high school, moved to Los Angeles to pursue acting. But his first big break was in New York, where he took on the role of Pedro Quinn in the Off Broadway play “Blade to the Heat,” a performance The New York Times described in 1994 as the show’s “most arresting.”

“More than any words he utters, the actor’s haunted eyes, sunken cheeks and shaved head convey the extent of Pedro’s torment,” David Richards, The Times’s theater critic, wrote. “In repose, he’s almost spectral. In the ring, he’s like a short circuit, and his silent scream of triumph is a guaranteed spine-tingler.”

In his longest-running and perhaps most widely known role, he was a gangster-turned-police officer, Antonio Vega, in the soap opera “One Life to Live.” De los Reyes appeared in nearly 300 episodes from 1995 to 1998 and from 2000 to 2009. After his character is released from his prison sentence for murder charges when it’s revealed he was acting in self-defense, he becomes a police officer and has a series of romantic entanglements.

The show, which ran from 1968 to 2012 mostly on ABC, was groundbreaking for its diverse cast, including the first Black actor to play a lead role on daytime television.
