💀 Batman Endgame (2014-2015): the final battle between Batman and the Joker
If Death of the Family showed the Joker attacking what Batman LOVES, Batman Endgame shows the Joker attacking what Batman IS. Published between 2014 and 2015 by the duo Scott Snyder and Greg Capullo at the peak of their New 52 run, this arc is the culmination of their collaboration and probably the most definitive Batman-Joker showdown ever written. The title itself — Endgame, the end of the game — makes the intent clear: this is meant to be the last fight, the one where everything is at stake, the one after which nothing will ever be the same. The Joker no longer wants to play with Batman. He wants to end their story in the most devastating way possible. To go further on this subject, see also Doctor Death (Karl Hellfern): Batman's very first supervillain.
This article explains why Endgame is considered the logical conclusion of the Snyder/Capullo era and one of the greatest Batman arcs of the 2010s. On the agenda: the diptych context with Death of the Family, the Joker's attack on the Justice League in the opening, the disturbing theory of an immortal Joker, the Joker virus ravaging Gotham City, the final battle in the caves beneath the city, and the ending that left its mark on readers. To place this work in the complete chronology, a detour through the overview of Batman comics by era provides the broader New 52 context.
Endgame at a glance
📚 The Snyder diptych: Death of the Family, then Endgame
To understand Endgame, you have to read it as the second half of a conceptual diptych. In Death of the Family (2012), the Joker offered Batman a twisted kind of love: he wanted to rid him of his family to make him purer, stronger, more alone. This was a Joker who loved Batman in his own warped way. In Endgame (2014), that logic is completely reversed. The Joker has realized that his love was never returned, that Batman never saw him as an equal or a partner. So he swings from love to total hatred. He no longer wants to seduce Batman or transform him. He wants to destroy him.
This emotional progression across two arcs is one of Snyder's major narrative achievements. It treats the Batman-Joker relationship as a full-fledged love-hate story, with its phases, its breakups, its escalations. Few writers have dared to push the almost romantic dimension of this antagonism so far. This psychological boldness places Endgame in the lineage of the great works that have explored the Joker's psyche, alongside The Killing Joke by Alan Moore. To understand the complete evolution of the Joker in all his versions, a detour through the complete history of the Joker provides the full mythological context.
The culmination of the New 52 run
Endgame arrives after several years of the Snyder/Capullo run, which had redefined Batman for New 52 continuity. After The Court of Owls , which reinvented Gotham's ancient history, and after Death of the Family, which brought back the Joker, Endgame is the emotional and narrative high point of the entire period. It is the arc in which Snyder draws on everything he has built to deliver the definitive confrontation. Being that high point gives the arc unmatched dramatic weight — readers feel they are witnessing something irreversible.
| Arc | What the arc does |
|---|---|
| The Court of Owls | Reinvents Gotham's ancient history |
| Death of the Family (2012) | The Joker wants to rid Batman of his family |
| Endgame (2014) | The Joker swings from love to total hatred |
⚡ The shocking opening: the Joker turns the Justice League against Batman
Endgame opens with one of the most spectacular sequences of the entire Snyder run. The Joker has managed to poison the Justice League — Superman, Wonder Woman, Flash, Aquaman, Green Lantern — and turns them all against Batman. The first half of the arc shows Batman facing, one by one, the most powerful members of the Justice League, compelled by the Joker's poison. This sequence is a tour de force: it demonstrates that Batman, the human without powers, can stand up to the most powerful beings on the planet thanks to his preparation and his intelligence.
The fight against Superman is particularly memorable. Batman, equipped with special armor and a piece of kryptonite chewing gum (a typical Snyder touch), takes on a poisoned Superman in the streets of Gotham. This scene perfectly illustrates Snyder's philosophy of Batman: he has a plan to neutralize every member of the Justice League, including his own allies, because he always anticipates the worst. This image of an ultra-prepared Batman with a plan for everything echoes his economic and intellectual rivalry with other billionaires such as Lex Luthor. To understand the dynamics of the Justice League, where Batman has to deal with super-powered beings, a detour through how the Justice League was created provides the team's context.
🧬 The disturbing theory: is the Joker immortal?
The most dizzying idea in Endgame is a theory that Snyder raises without ever fully resolving it: what if the Joker were immortal? The arc suggests that the Joker has existed in Gotham for centuries, that traces of him can be found in old photographs of the city, that he may be a supernatural force rather than a mere human criminal. This mythological dimension of the Joker — an eternal embodiment of the chaos that has haunted Gotham since its origins — gives the arc an almost cosmic depth.
Snyder ties this theory to a substance called "Dionesium," a compound similar to the Lazarus Pits that grant a form of regenerative immortality. Dionesium would explain the Joker's supernatural longevity and his ability to always come back. The arc remains deliberately ambiguous about whether the theory is true — the Joker himself mocks the idea and refuses to confirm or deny it. This ambiguity is typical of Snyder's genius: he never gives a definitive answer, leaving the mystery of the Joker intact. This supernatural dimension of the character anticipates later explorations such as Batman Who Laughs and the Dark Multiverse.
The Joker as a folkloric entity of Gotham
This idea of an immortal Joker turns the character into a kind of eternal bogeyman of Gotham, comparable to urban legends and folkloric figures. The Joker would not be just a criminal — he would be the very spirit of the cursed city, its dark side made flesh. This reading gives the Batman-Joker antagonism a mythological dimension: it is no longer a hero against a criminal, but order against primordial chaos, the rational against the eternal irrational. This conceptual elevation is one of Snyder's most lasting contributions to the Joker's mythology, and it shapes the way later writers handle the character.
In short
Snyder suggests, without settling the question, that the Joker has existed in Gotham for centuries thanks to Dionesium, a compound similar to the Lazarus Pits. The Joker himself refuses to confirm or deny this theory.
☠️ The Joker virus ravages Gotham
The heart of the action in Endgame is the Joker's release of a virus derived from his own toxin. The virus turns the people of Gotham into laughing, murderous creatures — "Jokerized" victims with frozen grins and bleached skin who attack everything in their path. All of Gotham becomes a battlefield where Batman must make his way through a population turned into the Joker's army. This urban epidemic gives the arc an apocalyptic scale worthy of the great zombie horror films.
Even members of the Batfamily and Batman's allies are infected, forcing Bruce to fight the people he loves while searching for a cure. This desperate situation thematically recalls the great crisis crossovers such as No Man's Land, in which Gotham becomes a zone of total chaos. But where No Man's Land was a natural disaster, the Joker virus is a deliberate, personal attack, designed specifically to break Batman morally by forcing him to fight his own city. This personalization of the catastrophe is what sets Endgame apart from other crisis arcs. To understand how Batman protects Gotham from his base, a detour through the Batcave provides the context of his infrastructure.
🕳️ The final battle in Gotham's caves
The climax of Endgame takes place in the underground depths of Gotham, in a network of ancient caves. It is there that Batman and the Joker face off one last time, far from the city, in a primal confrontation that brings their conflict back to its essence. This choice of setting — the caves, the underground, the geological origins of the city — is symbolically powerful. Batman and the Joker literally return to the roots of Gotham to conclude their story, as if their battle were as old as the city itself.
Without revealing the entire ending, so as to preserve the reading experience, Endgame closes on a note that seems final — the two enemies vanish together into the depths, sealing their shared fate. This ending, which seemed to close their story for good, made a deep impression on readers in 2015. Of course, comics being comics, neither Batman nor the Joker stays gone for very long. But in the moment, Endgame managed to create a feeling of finality that is rare in a medium where death is rarely permanent. This ability to move readers despite knowing that nothing is final is the hallmark of the greatest comic arcs. To explore the Joker's later return in the following decade, a detour through Joker War (2020) shows how the antagonism continues in the post-Snyder era.
Key point
Batman and the Joker face off one last time in ancient caves beneath Gotham and vanish together into the depths. This ending left its mark on readers in 2015, even though neither of them stays gone for long.
🦇 The legacy: the conclusion of an era
In conclusion, Batman Endgame will go down in Batman comics history as the masterful conclusion of the Snyder/Capullo era, one of the most respected in modern mythology. The arc accomplished several major things. First, it delivered the most definitive and emotionally charged Batman-Joker showdown of the 2010s. Second, it firmly established the theory of the immortal Joker as a mythological dimension of the character. Third, it demonstrated Snyder's narrative mastery in building a story across several arcs — Death of the Family and then Endgame forming a coherent, complete diptych.
The influence of Endgame can be seen in every later Batman arc. The Joker's supernatural dimension, the idea of Gotham as a city haunted by ancient forces, the love-hate relationship pushed to its peak — all of these elements have fed the creators of the 2020s. Endgame is also the arc that confirmed Greg Capullo as one of the greatest Batman artists of all time, his rendering of the Joker Jokerizing Gotham having become iconic. For readers who want to explore the whole Snyder era, the analyses of Black Mirror and the Court of Owls complete the trilogy. And to place this arc within the full comics continuity, the overview of Batman comics by era offers a historical map of the entire mythology, while the gallery of Gotham villains details every antagonist in the universe.
