Conroy had unfortunately been dealing with cancer for a while, though I think for a lot of us this is probably our first time hearing this news.
This is one VA death that is pretty shocking to me as Conroy was actually the first Batman I knew growing up and his voice was just such a great fit for the character, and I remember being absolutely ecstatic when he returned to the role for Rocksteady's Arkham trilogy.
RIP Kevin Conroy, he'll always be my favorite Batman.
