Batcave (Arkham Island)

The Batcave is an underground cave system located below Arkham Island.

Batman: Arkham Asylum
Batman created a small Batcave under Arkham Island and stored some supplies there just in case a massive breakout would occur in Arkham. That breakout became reality when the Joker managed to take over Arkham as the first stage of trying to take control of Gotham. This Batcave proved useful for Batman as it allowed him to analyse the Titan formula and defeat the Joker. During that time, Joker attempted to take control of the Batcave by using his thugs who were defeated by Batman. The Batcave was destroyed by Poison Ivy's plants when she was injected with Titan.
