The Batcave is Batman's secret headquarters, consisting of a series of subterranean caves beneath his mansion, Wayne Manor. As his command center, the Batcave serves multiple purposes; supercomputer, surveillance, redundant power-generators, forensics lab, medical infirmary, private study, training dojo, fabrication workshop, arsenal, hangar and garage. It houses the vehicles and equipment Batman uses in his campaign to fight crime. It is also a trophy room and storage facility for Batman's unique memorabilia collected over the years from various cases he has worked on. In both the comic Batman: Shadow of the Bat #45 and the 2005 film Batman Begins, the cave is said to have been part of the Underground Railroad.
Kane signed away ownership in the character in exchange for, among other compensation, a mandatory byline on all Batman comics. This byline did not originally say "Batman created by Bob Kane"; his name was simply written on the title page of each story. The name disappeared from the comic book in the mid-1960s, replaced by credits for each story's actual writer and artists. In the late 1970s, when Jerry Siegel and Joe Shuster began receiving a "created by" credit on the Superman titles, along with William Moulton Marston being given the byline for creating Wonder Woman, Batman stories began saying "Created by Bob Kane" in addition to the other credits.
One of the most iconic fictional characters in the world, Batman has dedicated his life to an endless crusade, a war on all criminals in the name of his murdered parents, who were taken from him when he was just a child. Since that tragic night, he has trained his body and mind to near physical perfection to be a self-made Super Hero. He's developed an arsenal of technology that would put most armies to shame. And he's assembled teams of his fellow DC Super Heroes, like the Justice League, the Outsiders and Batman, Incorporated.
Intimidation: It is widely known that Batman has the ability to instill fear in others, even the people that know him best are intimidated by him. Even those who aren't afraid of the likes of Superman fear Batman. His ability to inspire great fear made him eligible for induction into the Sinestro Corps, although he was able to fight off the power ring's control.
