Even after Bruce loses all memory of his life as Batman, the cave was still used by other members of the Bat-Family; Alfred took the de-powered Clark Kent to the cave to explain what had happened to Bruce, and Dick Grayson and the various Robins used it as a base of operations while opposing the schemes of the ruthless "Mother" in "Batman and Robin Eternal". When new villain Mr Bloom launches a massive attack on Gotham, Alfred is forced to allow Bruce into the Batcave to access an apparently-disregarded program designed to upload Bruce's memories to a series of Batman clones to maintain his legacy, Bruce overcoming the original project's limitation of being unable to upload the memories to a fresh body by having Alfred take him to the point of brain death and then download the data onto his blank brain. The Batcave serves as Batman's secret headquarters and command center, where he monitors all crisis points in Gotham City, as well as the rest of the world. The cave's centerpiece is a supercomputer whose specs are on par with any of those used by leading national security agencies; it permits global surveillance and also connects to a massive information network as well as storing vast amounts of information, both on Batman's foes and his allies. A series of satellite link-ups allows easy access to Batman's information network anywhere around the globe. The systems are protected against unauthorized access, and any attempt to breach their security immediately sends an alert to Batman or Oracle. Despite the power of Batman's computers, the Justice League Watchtower is known to have more powerful computers (composed of Kryptonian, Thanagarian and Martian technology), and Batman does occasionally use them if he feels his computers are not up to the task; on occasion he also consults Oracle for assistance. Additionally, the cave features state-of-the-art facilities such as a crime lab, various specialized laboratories, mechanized workshops, personal gymnasium, parking, docking and hangar space (as appropriate) for his various vehicles as well as separate exits for each type, memorabilia of past campaigns, a vast library, a large bat colony, and a Justice League teleporter. It also has medical facilities as well as various areas used in training exercises for Batman and his allies. The cave houses Batman's vast array of specialized vehicles, foremost being the famous "Batmobile" in all its incarnations (mostly for nostalgia, but also for contingencies, as all are serviceable and in excellent working condition). Other vehicles within the complex include various motorcycles, air- and watercraft such as The Bat-Wing, a single-occupant supersonic jet, and the Subway Rocket (which debuted in "Detective Comics" #667).
