SPOILER WARNING: This article contains major spoilers for "Crisis on Infinite Earths, Part 2," the second installment of this year's Arrowverse crossover.

Another hero has fallen in the second chapter of "Crisis on Infinite Earths."

Kevin Conroy's Bruce Wayne was killed by his younger cousin, Batwoman's Kate Kane, while the two talked and then fought inside Conroy's Batcave. Kate learned that this version of Bruce Wayne had broken his oath of no killing, and sensing how twisted he is, kicked him into a piece of equipment, resulting in Conroy being electrocuted thanks to his metal exoskeleton.

Conroy recently revealed his main "Crisis" scenes feature Rose and Melissa Benoist's Supergirl, who helped him transition from voicing Batman to playing him in live-action.

"Everybody was so generous to work with," said Conroy. "I can't emphasize enough how welcoming everyone was, especially Ruby. She is so open and giving. I just fell into her eyes at one point and we just connected on camera. It was wonderful."

"Crisis on Infinite Earths" continues in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
