Batman
Technology

Batman utilizes a vast arsenal of specialized, high-tech vehicles and gadgets in his war against crime, the designs of which usually share a bat motif. Batman historian Les Daniels credits Gardner Fox with creating the concept of Batman's arsenal with the introduction of the utility belt in Detective Comics #29 (July 1939) and the first bat-themed weapons the batarang and the "Batgyro" in Detective Comics #31 and 32 (Sept. and October 1939).

Batman's batsuit aids in his combat against enemies, having the properties of both Kevlar and Nomex. It protects him from gunfire and other significant impacts, and incorporates the imagery of a bat in order to frighten criminals.

The details of the Batman costume change repeatedly through various decades, stories, media and artists' interpretations, but the most distinctive elements remain consistent: a scallop-hem cape; a cowl covering most of the face; a pair of bat-like ears; a stylized bat emblem on the chest; and the ever-present utility belt. His gloves typically feature three scallops that protrude from long, gauntlet-like cuffs, although in his earliest appearances he wore short, plain gloves without the scallops. The overall look of the character, particularly the length of the cowl's ears and of the cape, varies greatly depending on the artist. Dennis O'Neil said, "We now say that Batman has two hundred suits hanging in the Batcave so they don't have to look the same...Everybody loves to draw Batman, and everybody wants to put their own spin on it."

Finger and Kane originally conceptualized Batman as having a black cape and cowl and grey suit, but conventions in coloring called for black to be highlighted with blue. Hence, the costume's colors have appeared in the comics as dark blue and grey; as well as black and grey. In the Tim Burton 's Batman and Batman Returns films, Batman has been depicted as completely black with a bat in the middle surrounded by a yellow background. Christopher Nolan 's The Dark Knight Trilogy depicted Batman wearing high-tech gear painted completely black with a black bat in the middle. Ben Affleck 's Batman in the DC Extended Universe films wears a suit grey in color with a black cowl, cape, and bat symbol. Seemingly following the suit of the DC Extended Universe outfit, Robert Pattinson 's uniform in The Batman restores the more traditional gray bodysuit and black appendage design, notably different from prior iterations by mostly utilizing real world armor and apparel pieces from modern military and motorcycle gear.

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 (originally a relatively traditionally, but bat-motifed plane, later seen as the much more unique "Batwing" starting in the 1989 film), 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, which was before frequently depicted to resemble a sports car, 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 keeps most of his field equipment in his utility belt. Over the years it has shown to contain an assortment of crime-fighting tools, weapons, and investigative and technological instruments. Different versions of the belt have these items stored in compartments, often as pouches or hard cylinders attached evenly around it.

Since the 1989 film, Batman is often depicted as carrying a projectile which shoots a retractable grappling hook attached to a cable (before this, a he employed a traditionally thrown grappling hook.) This allows him to attach to distant objects, be propelled into the air, and thus swing from the rooftops of Gotham City.

An exception to the range of Batman's equipment are hand guns, which he refuses to use on principle, since a gun was used in his parents' murder. In modern stories in terms of his vehicles, Batman compromises on that principle to install weapon systems on them for the purpose of non-lethally disabling other vehicles, forcing entry into locations and attacking dangerous targets too large to defeat by other means.

When Batman is needed, the Gotham City police activate a searchlight with a bat-shaped insignia over the lens called the Bat-Signal, which shines into the night sky, creating a bat-symbol on a passing cloud which can be seen from any point in Gotham. The origin of the signal varies, depending on the continuity and medium.

In various incarnations, most notably the 1960s Batman TV series, Commissioner Gordon also has a dedicated phone line, dubbed the Bat-Phone, connected to a bright red telephone (in the TV series) which sits on a wooden base and has a transparent top. The line connects directly to Batman's residence, Wayne Manor, specifically both to a similar phone sitting on the desk in Bruce Wayne's study and the extension phone in the Batcave.

The Batcave is Batman's secret headquarters, consisting of a series of 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 book Batman: Shadow of the Bat #45 and the 2005 film Batman Begins, the cave is said to have been part of the Underground Railroad.
