I came around to the Tom King Batman train a lot later than most for reasons now well documented on Bleeding Cool, and Batman Annual #2 by King, Lee Weeks, and Michael Lark is a big part of the reason I ever came around to it all.
Also, side note, yes I know the "Batman-Hater Holiday Special" posts were put up in reverse order. There was a lot of scheduling confusion, which was entirely my fault.
Batman Annual #2 is a heartfelt and beautiful tale of the first meeting and last days shared by Batman and Catwoman. The resulting comic works entirely off its characters, emotion, and phenomenal artwork.
The sweet, little moments shared between Bruce and Selena in this comic are enough to melt the heart of even the most bitter readers. It effectively cements Batman and Catwoman as one of those classic couples on par with Superman and Lois Lane or Spider-Man and Mary Jane.
The ending is gripping enough that I have no shame in admitting that I almost teared up in public while reading it. This comic really is one of the main reasons that I was won over into loving the Batman once again.
Lee Weeks and Elizabeth Breitweiser give a solid noir feeling to the first half, which really matches the feeling of their first meetup: a wild thief and a grim detective discovering each other's secrets. Michael Lark and June Chung give a more understated feeling to the quieter latter days of Bruce Wayne and Selena Kyle.
Batman Annual #2 is a masterpiece of Batman storytelling. It shows how and why this couple works so well, it wins you over, and it warms your heart in a way you would never expect from a comic about the Caped Crusader. It easily won its place on this list.
