The story involves the return of Batman's archenemy, the Joker, and his plan to destroy Bruce Wayne's reputation in Gotham City.
Joker, enraged at the thought, bashes the clown's head in for daring to even think this, as it would ruin his fun and rivalry with Batman.
He then drugs and forces Lucius Fox to give him access to all of Batman's weapons after completing a hostile takeover of Wayne Enterprises.
He also hires armies of thugs and uses them and Batman's weapons to terrorize and destroy the city while the GCPD is forced to stand by and watch.
This, along with Joker supplying and paying his army and bribing the city government, severely depletes the Wayne fortune by the tens of billions.
Batman gathers Dick Grayson, Jason Todd, Tim Drake, Cassandra Cain, Barbara Gordon, Stephanie Brown, Duke Thomas, and Harley Quinn.
Other Batman comics expanded on small elements of the larger ongoing storyline: The main story received generally positive reviews for the action, plot, and art style.
[2] Derek McNeil from DC Comics News wrote that "Tynion has done a masterful job of setting up the ultimate showdown between Batman and the Joker.
If the creatives can keep this energy going for the rest of this storyline The Joker War could find itself a spot among the great stories in the Dark Knights history".
[6] Jeffrey Movie Files wrote: "The Joker War is building to its conclusion with #100, but at this rate, Tynion really could take longer in playing it out as its been an amazing ride so far".
James Tynion and Jorge Jimenez bring everything together to provide a strong set-up for the final chapter of Joker War.
Hopefully Batman #100's increased page count will help in fixing these story problems and wrap up Joker War in a satisfying way".
