Joseph Chill (Earth-1352)

"Your Honor... not a day goes by that I don't wish I could take back what I did. Sure, I was desperate, like a lot of people back then... but that don't change what I did."

- - Joe Chill

Joseph "Joe" Chill was a hitman operating in Gotham City who was the responsible for the deaths of Thomas and Martha Wayne in front of their son, Bruce, when he was a child, under orders of then Mayor Hamilton Hill. The event led Bruce to develop post-traumatic stress disorder, and in years, become the vigilante Batman.
