The Batcave is the underground headquarters of Batman underneath Wayne Manor.
History[]
Batman Unlimited: Animal Instincts[]
The cave first appears at the beginning, where Red Robin was training with the training robots, and Batman analyse the robberies caused by Cheetah, Silverback, Man-Bat and Killer Croc around Gotham City.
Later, Batman and his allies brought Man-Bat to the cave, and cured him of his mutation.
Batman Unlimited: Monster Mayhem[]
When the Joker infected all of Gotham's technology with his digital laughing virus, Batman and his allies used old-fashioned brainpower with the use of books and maps in the Batcave when the Batcomputer was out of action.
Batman Unlimited: Mechs vs. Mutants[]
Damian Wayne, the current Robin, used the Batcomputer in the cave to study old video footage of his father's previous battles with the Joker, and the file on the Penguin.
After thwarting Penguin's plans with the help of a reformed Mr. Freeze to destroy Gotham from the mutated Bane, Clayface, Killer Croc and Chemo, Batman and his allies share a coffee at the cave.
