If you are a DC animated fan, I have the sad duty to announce that Kevin Conroy, the actor of Batman - The Animated Series, the Justice League and Justice League Unlimited series, dozens of assorted Batman movies, and video games has passed away. This undoubtedly is one of the toughest announcements to make. But, upon discovery of some failing health, we've lost Kevin Conroy. We've lost the most dynamic voice of the Batman animated universe. He is the only one I know that can be Bruce Wayne in one episode, then the Dark Knight the next and go full tilt on the Joker and his goons.
Sadly, without Conroy, Mark Hamill (the voice of Joker) has no punchline. I mean, Hamill was the yin to Conroy's yang. Much like how Fred Welker is the yin to Peter Cullen's yang in the Transformers universe. Both Conroy and Hamill's dynamics worked so well in the original series, movies and games, I'm afraid nothing will top that sort of pairing.
In such a time as this while our nation grapples with an unknown future, we take this time now to remember Kevin Conroy, the purely badass modern Batman we've come to know. As such, we as fans of the series are all the Dark Knight.
I am vengeance. I am the Knight. I. Am. Batman!
Conroy's Wikipedia article says he had intestinal cancer.
