“I didn’t have to go easy on you. A different binding agent, a stronger mix… I want you to remember that. I wanted to remind you to stay out of my way. In all the years to come, in your most private moments, I want you to remember the one man who beat you!” – Batman: The Dark Knight Returns, Part 2 (2013)
Said iconic quote, spoken by an armored Batman to a roughed up Superman (Mark Valley), had already made its screen debut in the second part of the animated Batman: The Dark Knight Returns adaptation anyway. At the peak of the their thunderous physical conflict at Crime Alley, it appears Bruce Wayne will earn the ultimate victory and wants to make sure Superman realizes how much he enjoys having the upper hand, right before succumbing to a heart attack. However, after hearing heart beats from his grave, Clark Kent discovers that his friend is still alive and he really did become the sole victor against the Man of Steel.
