DC with its multiverses and multiple crises can get confusing in a hurry, especially for the Justice League. That doesn't mean it lacks great stories though. Some of the Justice League's greatest adventures revolve around these crises in fact, yet less metaphysical Justice League storylines also offer a lot to celebrate. At the end of the day, there are a ton of great Justice League comic books.
The best Justice League stories are the ones that really dig deep into the various characters, analyzing their fundamental values and their interpersonal relationships. Of course, there's always great action to be had with what are essentially (and sometimes literally) the seven gods of the DC Universe. And with so many different writers to pen these tales, there's no shortage of variety in how the heroes are represented.
So here are some of the best Justice League comics. Prepare for a whole bunch of Grant Morrison. And spoilers. There will be spoilers.
Mark Waid and Alex Ross team-up to write a tale set in the future with an aged and retired Justice League in Kingdom Come. The world is overrun by vigilantes with looser morals than traditional heroes, which are still in existence doing their own part to defend the world, and conflict arises between the two sides. The Justice League members are forced to come out of retirement to put a stop to the escalating violence. Of course, Lex Luthor gets in the middle of things, further complicating matters, ultimately resulting in the death of a hero. The story deals with the hallmark theme of DC: the tenuous nature of superheroes' relation to humanity, viewed as both saviors and dangerous gods.
Tower Of Babel
Tower of Babel is an intriguing tale of internal strife amongst the Justice League members. Written by Mark Waid, it reveals just how cunning and calculating Batman is, almost to the point of making him less human than his super-powered colleagues. We discover that Batman has created contingency plans to eliminate each Justice League member should they somehow be compromised, but he didn't consider what would happen if his contingency plans themselves were compromised. Ra's al Ghul gets his hands on them and all hell breaks loose, leading to some serious drama between the heroes, and some interesting philosophical questions.
Even if you've never picked up a comic book, there's a good chance you've heard of Crisis on Infinite Earths. This storyline is one of the grandest in all of comics, with some of the most famous heroes dying in multiple universes, and ultimately doing away with the multiverse entirely. Written by Marv Wolfmanand and George Pérez, Crisis on Infinite Earths served a function, but it wasn't simply a utility - it was traumatic and expansive; a truly epic comic book story.
In Alex Ross's upside down JLA story Justice, the Legion of Doom fear that the Justice League of America are actually insufficient defenders of the world, so they plot to destroy them in order to become the true defenders of Earth. Each Justice League member ends up facing threats tailored specifically to them, and the heroes find themselves dispersed and greatly weakened. Ultimately, the Joker of all people ends up playing an integral role in saving the day, which in and of itself makes this a must read.
