"It was a regular home, away from home."
—Batman explaining it's origins to Oracle

The Batcave on Arkham Island is a secondary headquarters built below Arkham Asylum as a precaution should he ever be separated from the primary Batcave under Wayne Manor. This "Batcave" is one of many "satellite-caves" established by Bruce Wayne as a base-of-operations within Gotham City. Batman used this particular Batcave as his base of operations during the Arkham Asylum Incident.

Suspended over an abyss, the cave possesses its own Batcomputer, an emergency Batwing, and various utility tools to complement the tools that Batman already carries. The cave is accessible from various points and has a security entrance at the base of Dead Man's Point, as well as access to Arkham Island's underground caves and old sewer system.

Incident Reports[]

Before Arkham Asylum Incident[]

At an unknown period of time, Batman discovered a cave system beneath Arkham Island after saving an inmate from falling to his death. He established a "satellite-cave" within it to serve as an emergency base of operations for rest and re-supply. Batman kept that Batcave a secret even from his most trusted allies.

Arkham Asylum Incident[]

After he discovered that Dr. Penelope Young might be involved in creating a formula by using Venom as a base, Batman contacted Oracle to investigate while he made his way to the satellite-cave via Dead Man's Point.
Once in the cave, Batman accessed the Batcomputer and deduced the Joker's plan to use Dr. Young's formula to create an army of Bane-like monsters. Batman returned to the surface, and later returned to the cave to create an antidote for the formula, named Titan, just as the Joker injected Poison Ivy with it. Ivy's powers over her plants increased dramatically, and, in her attempt to strangle Arkham Island in colossal vines, penetrated and destroyed the Batcave.

After both Arkham Asylum and the island were shut down and turned into TYGER's HQ, Batman likely abandoned this Batcave.
