This is the story that takes place more than a decade later, when Superman and Batman are getting old.
The new generation of superheroes has taken over the responsibilities of the older generation of heroes.
The elderly Batman has receded behind the scenes, and his favored Terry McKinas is trained by him as the new Batman, the future Batman.
The future Batman replaces the elderly Batman in the major event "Doomsday Future" to save the world destroyed by the brother's eye.
I won't talk about that big incident of pit daddy, it's not interesting.
In this future, the Joker died in a battle with Batman more than a decade ago.
But what Batman didn't expect was that the Joker's men took the Joker's body with them.
And freeze him.
Over time, a clown's fanatical admirers formed a gang called the Clown Gang.
All of the gang members are almost crazy, and they behave exactly like the clown's madness.
They even created a place in a corner of the city called Clown City.
This group of lunatics even dared to attack the police who went there to investigate.
It was all caused by a man called Terminal.
He used his current technology to resurrect the Joker, a man who had been lying in the freezer for more than a decade.
A long-lost horror legend in Gotham City.
“Joker！”
This makes the Joker Gang one of the scariest gangs in the city.
The future Batman Terry really has a bitter heart, and this group of neuropaths has really resurrected the Joker.
The most infuriating thing is that the clown gang has so many crazy people crazy to join!
They used the money in the Joker's account as funds, and even restored Bane's poison experiment.
And combined his experiments with the Joker, and successfully created this kind of thing as the Clown Bane Ensemble.
This new technology succeeded in making one of their members infinitely powerful.
The future Batman was forced by the Joker gang to escape from this place called Joker City.
So what is he supposed to do with this bunch of crazy guys?
