Synopsis
As Nightwing and Oracle enjoy a romantic meal outside Gotham, a riot in the Slabside
Penitentiary is making headline news - it has been instigated by the Joker in response to
learning the news that he has a fatal brain tumour. Oracle ponders how many lives would
have been saved if someone had just killed the Joker long ago. Joker meanwhile, is killing
Multi-Man time after time, hoping that he will ressurect with a useful power. Eventually,
he gains an explosive ability, clearing the way for the Slab inmates to access other floors
of the penitentiary. Shilo Norman realises with horror that they are on their way to bust
the powerful Doctor Polaris out.
The warden of Slabside orders the use of all available inhibitors on the inmates - the
regurgitants didn't work, so the metagene inhibitor gas is put into operation. The
inmates are horrified, apart from the Joker. When Black Canary, who discovered the riot
and sneaked into the prison, comes upon the villains, she discovers why - they've all been
transformed into carbon copies of the Joker: chalk-white skin, green hair, hideous smile
and incessant cackling. At that moment, Oracle returns to her appartment and is horrified
to find out what's been happening.
