The Joker's Video Threat was a video broadcasted on Gotham City News and involved Brian Douglas, one of the Batmen, and the Joker, who at some point, kidnapped Douglas and began to torture him in a slaughterhouse.
The video began with the Joker asking Brian Douglas his name, which he replied. He was then asked if he was the real Batman, which Brian simply said "No". The Joker started laughing at his response, removed Douglas' mask and barked, "Then why do ya dress up like him?!" Brian bravely replied that the reason of his imitation was because Batman is a symbol that everyone doesn't have to be afraid of criminal scum such as the Joker. The Joker wasn't buying this reply and proceeded to viciously interrogate Brian while he sat weeping in fear. He asked for his opinion on Batman making Gotham City a better place, and demanded fiercely for Brian to face him. Everything became silent for a few seconds, and the Joker now turned the camera on himself, making his speech on how "crazy" Batman made Gotham. If Gotham wanted order, the clown demanded that Batman should take off his mask and turn himself into the police. However, if he refuses to do so, people will die everyday, starting on that night. He stated that he made his promises and began to laugh maniacally as he started lunging at Brian off-camera as the image shook madly. Brian was heard screaming in reaction to whatever was happening.
Afterwards, Brian's body was hanged outside the window of the Mayor Anthony Garcia's office at Gotham City Hall with his face painted like the Joker and his mouth cut into a glasgow smile like the Joker's, interrupting the mayor's conversation with Harvey Dent, and the video was released to the public. Bruce Wayne was given the message but continued to set up the fundraiser for that night.
