The Batcve was the secret underground headquarters of Batman. It's located beneath Wayne Manor.
History[]
The cave was discovered by Bruce during his marriage proposal to Andrea Beaumont. The caverns were located beneath Wayne Manor. This is where Bruce designed his first Batsuit and dons the cowl of Batman for the first time.
It is also where Batman took Dick Grayson to show him his secret identity.
In Heart of Steel: Part I, Randa Duane infiltrated the cave, learned Batman's secret and tampered with the Central Computer Console, and takes the design specs of the wetware chips, under HARDAC's orders.
In His Silicon Soul, the Batman robot used the Batcomputer to download HARDAC into it.
In the flashback of Old Wounds, Bruce shows Barbara the cave and his secret identity for Dick's sake.
In Sins of the Father, Tim Drake discovered the cave and Batman and Batgirl's identities.
When Bruce retired as Batman in Rebirth: Part I, he shuts down the Batcave and vowed never to be Batman again. Twenty years later, Terry McGinnis, a teenager, discovers the cave and learns Bruce's secret. In Rebirth: Part II, Terry steals the Batsuit to stop Derek Powers from shipping a virus and avenge his father Warren McGinnis who was killed by Mr. Fixx. After defeating Powers and Fixx, Bruce allows Terry to be Batman and monitor him on the Batcomputer.
