Though not much had changed in regard to terms of costume between films, the difference of the slightly more sleek symbol and the armor makes us think that Batman has decided that he needs to up his game, both in terms of fashion and fighting, and keep up with the kind of criminals that Gotham seems to be producing at an increasingly alarming rate.
By 1964, sales of Batman titles had fallen drastically. Bob Kane noted that, as a result, DC was "planning to kill Batman off altogether". In response to this, editor Julius Schwartz was assigned to the Batman titles. He presided over drastic changes, beginning with 1964's Detective Comics #327 (May 1964), which was cover-billed as the "New Look". Schwartz introduced changes designed to make Batman more contemporary, and to return him to more detective-oriented stories. He brought in artist Carmine Infantino to help overhaul the character. The Batmobile was redesigned, and Batman's costume was modified to incorporate a yellow ellipse behind the bat-insignia. The space aliens, time travel, and characters of the 1950s such as Batwoman, Ace, and Bat-Mite were retired. Bruce Wayne's butler Alfred was killed off (though his death was quickly reversed) while a new female relative for the Wayne family, Aunt Harriet, came to live with Bruce Wayne and Dick Grayson.
Batman is a comic book superhero character created in 1939 by the writer/illustrator team of Bill Finger and Bob Kane. He is a DC Comics character, first appearing in the Detective Comics #27. He has many features that differ from other comic book superheroes, including an extremely dark personality that tends to show little remorse when he exacts vigilante justice on various villains. Also, so many people have “recreated” Batman over the years that there are significant inconsistencies in the way the character behaves, is perceived, and looks, and there are also many different takes on the degree or lack thereof of participation that Batman’s sometimes sidekick Robin is involved in his story.
The "Batman: Hush" storyline introduced Tommy Elliot, a childhood friend of Bruce Wayne's. As Hush, the bandaged villain, Elliot secretly orchestrates constant attacks on the Batman by manipulates many of the Batman's Rogues Gallery's villains. As the manipulations and orchestrations grow so does the sexual tension between Batman and Catwoman, to the point where they actually become romantically involved? to a certain degree. Ultimately, Batman's distrust in Catwoman ends the doomed relationship. Hush tricks Batman into believing that Jason Todd, the second Robin who was killed by the Joker, is actually alive. An angry Jason fights Batman but he is later revealed to be none other than Clayface. In a bizarre twist of writing, the DC creators decided to go ahead and let Jason Todd actually become alive, imagine that, but he arrives in the guise of ? the Red Hood.
