15Batman - Dark Knight Returns
In Frank Miller's seminal classic The Dark Knight Returns, when Batman comes out of retirement and starts causing a whole load of problems in Gotham City, the President of the United States (in this case rel="noopener noreferrer">Ronald Reagan

When Batman doesn't take Superman's warnings to heart, the Man of Steel is left with no choice but to take his old friend down, but Batman is no pushover. In one of the greatest knockdown, drag-out fights in comics. In the end, the entire fight was part of Batman's plan, something Superman had no idea of until well after the fact.
This battle, now over thirty years old, has continued to stand out as one of the best fights to ever end up on the four-color page and served as the jumping off point for Batman v Superman: Dawn of Justice.
