This was the best shown version of a predecessor to the legitimate bat suit, as other versions simply showed a fully trained Bruce in street clothes using his skills to disguise himself. In the main scene featuring the suit, we see Bruce fight his teacher Ducard and he uses a sword, the surrounding area and the bracers to high effect, although he does lose the training exercise.
One of the first suits we see from Christopher Nolan’s Batman Begins is Bruce Wayne’s League of Shadows training garb. While mostly built for ease of movement and warmth, the uniform also includes the armor bracers and triangle blades which are present in most bat suits, which is why we count it as a prototype of sorts. This was a great suit because we got to see that Bruce was obviously taught how to use minimal weapons and tricks, but could if need be.
Additionally, members of the group Batman, Incorporated, Bruce Wayne's experiment at franchising his brand of vigilantism, have at times stood in as the official Batman in cities around the world. Various others have also taken up the role of Batman in stories set in alternative universes and possible futures, including, among them, various former proteges of Bruce Wayne.
Batman is often treated as a vigilante by other characters in his stories. Frank Miller views the character as "a dionysian figure, a force for anarchy that imposes an individual order". Dressed as a bat, Batman deliberately cultivates a frightening persona in order to aid him in crime-fighting, a fear that originates from the criminals' own guilty conscience. Miller is often credited with reintroducing anti-heroic traits into Batman's characterization, such as his brooding personality, willingness to use violence and torture, and increasingly alienated behavior. Batman, shortly a year after his debut and the introduction of Robin, was changed in 1940 after DC editor Whitney Ellsworth felt the character would be tainted by his lethal methods and DC established their own ethical code, subsequently he was retconned as having a stringent moral code. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.
