In celebrated cartoon series, movies, and video games, a talented voice actor created the caped crusader’s distinctive voice.

Kevin Conroy, a well-known voice actor whose solemn delivery on Batman: The Animated Series was for many Batman fans the unmistakable sound of the cape-wearing vigilante, passed away at the age of 66.

Producer of the series Warner Bros. revealed on Friday that Conroy had passed away following a battle with cancer.

Conroy frequently appeared alongside Mark Hamill’s Joker as Batman in the renowned animated series that aired from 1992 to 1996.

He went on to voice Batman in a whopping fifteen movies, four hundred television episodes, and twenty video games, including the Batman: Arkham and Injustice series.

No one has played the Dark Knight more in the eight decades of Batman.

According to Hamill in a statement, “He has been the undisputed Batman for several generations.

It was one of those instances where everything came together perfectly and the world was made better because they selected the ideal candidate for the job.”

Conroy’s portrayal of the Dark Knight “will forever stand among the finest interpretations of the Dark Knight in any medium,” according to a statement from Warner Bros Animation.

Conroy began the role with no prior experience in voice acting or comics. His Batman was a dark, heavy character. Bruce Wayne in this version was slim and dashing.

He claimed that the 1930s movie The Scarlet Pimpernel, about an English aristocracy who leads a double life, served as his inspiration for the conflicting voices.

Conroy stated to The New York Times in 2016 that it was “so much pleasure as an actor to sink your teeth into.” “To call it animation is an injustice. It resembles mythology more.”

Over the years, Conroy’s performance changed and occasionally included references to his personal life. Conroy claimed that his own father was an alcoholic and that while he was in high school, his family broke apart. The 1993 animated movie Mask of the Phantasm, which focused on Bruce Wayne’s unresolved problems with his parents, was the result of him channeling those feelings.

Conroy wrote a comic book called Finding Batman about his unexpected experiences with the character and as a gay guy in Hollywood. It was published earlier this year.

He remarked, “I’ve frequently wondered how appropriate it was that I should land this role.

“As a gay child growing up in a devoutly Catholic home in the 1950s and 1960s, I’d become skilled at concealing parts of myself.”

He claimed that a voice he didn’t recognize—one that “seemed to shout from 30 years of rage, misunderstanding, denial, love, and yearning”—emerged within Conroy for Batman.

He remarked, “I felt Batman rising from deep within.”
