Expert Inquisitor: Batman is adept in the use of interrogation techniques, employing anything from law enforcement methods to outright torture. Several techniques have been seen, include hanging a person over the edge of a building by one leg or chaining a person upside down and beating them. He usually just plain uses his frightening appearance to get answers. "Fear is an excellent motivator" he once said."
The informal name "Batman family" is used for a group of characters closely allied with Batman, generally masked vigilantes who either have been trained by Batman or operate in Gotham City with his tacit approval. They include: Barbara Gordon, Commissioner Gordon's daughter, who has fought crime under the vigilante identity of Batgirl and, during a period in which she was confined to a wheelchair due to a gunshot wound inflicted by the Joker, the computer hacker Oracle; Helena Bertinelli, the sole surviving member of a mob family turned vigilante, who has worked with Batman on occasion, primarily as the Huntress and as Batgirl for a brief stint; Cassandra Cain, the daughter of professional assassins David Cain, and Lady Shiva, who succeeded Bertinelli as Batgirl.
Batman's primary vehicle is the Batmobile, which is usually depicted as an imposing black car, often with tailfins that suggest a bat's wings. Batman also has an aircraft called the Batplane (later called the "Batwing"), along with various other means of transportation. In proper practice, the "bat" prefix (as in Batmobile or batarang) is rarely used by Batman himself when referring to his equipment, particularly after some portrayals (primarily the 1960s Batman live-action television show and the Super Friends animated series) stretched the practice to campy proportions. For example, the 1960s television show depicted a Batboat, Bat-Sub, and Batcycle, among other bat-themed vehicles. The 1960s television series Batman has an arsenal that includes such "bat-" names as the bat-computer, bat-scanner, bat-radar, bat-cuffs, bat-pontoons, bat-drinking water dispenser, bat-camera with polarized bat-filter, bat-shark repellent bat-spray, and bat-rope. The storyline "A Death in the Family" suggests that given Batman's grim nature, he is unlikely to have adopted the "bat" prefix on his own. In The Dark Knight Returns, Batman tells Carrie Kelley that the original Robin came up with the name "Batmobile" when he was young, since that is what a kid would call Batman's vehicle. The Batmobile was redesigned in 2011 when DC Comics relaunched its entire line of comic books, with the batmobile being given heavier armor and new aesthetics.
Batman refuses to fight his friends and allows himself to be captured. Scarecrow infects him with a mind control toxin, but Batman had already taken an antidote, so he pretends to be under Scarecrow's control in order to foil his plan. Scarecrow reveals he will spread his new toxin across the Eastern Seaboard with blimps, so Batman slips the counteragent he developed into Scarecrow's toxin. Everyone infected is cured and Batman takes Scarecrow to prison. Batman later talks with Catwoman about the relationship they shared while they were in Gothtopia. Although Catwoman wants to have a relationship with Batman, he is not interested.
After revealing this knowledge to the original Dynamic Duo, Tim argued the need for a Robin to give the Dark Knight hope, especially when faced with a seemingly hopeless and unyielding war on crime. Though reluctant at first, Batman gave Tim the opportunity to prove that he was as good as his word. After months of grueling training, Tim Drake became the third Robin.
In the current Prime Earth continuity, Julie is an artist and her father is Mallory Madison, an arms dealer who sold the gun that was used to kill Bruce's parents. Julie first dated Bruce Wayne during their teenage years, but met him again after his mind had been erased and he had forgotten ever being Batman. The two fell passionately in love, with Bruce being prepared to settle down and marry Julie. However, things got so bad in Gotham that Alfred realized Batman was needed and he and Julie were forced to give Bruce his old memories back, erasing his mind of the relationship.
Harley Quinn: Best known as "The Joker's Girlfriend", Harley has had occasional romantic encounters with Batman, most notably her kiss with him in the episode Harley's Holiday from Batman: The Animated Series. Recently, in the The New 52, there have been a couple of stories in which Harley became infatuated either with Bruce Wayne or Batman. These attractions appear to be entirely one-sided and Batman has shown no signs of attraction towards Harley.
