Batman #423
Crook holding woman hostage at gunpoint, Bats helpless before him,
Crook: "I'll blow her head off! I swear I will!"
Bats (slowly moving toward crook and woman: "...and I swear that if you harm that woman at all, I'll make you pay! I will break and twist things within you. You can't conceive of the pain I can cause. It's pain that will go on forever! You won't escape it...because I won't let you die!"
Needless to say, things ended all right that time.
