The Revamp of the DC Animated Universe — sometimes referred to as the "New Look" — was the streamlining of the style of animation present within the cartoons belonging to said universe.
When production of the first two seasons of Superman: The Animated Series ended and production of The New Batman Adventures began, the animators at Warner Bros. Animation determined to unify the style of the two shows, redoing the art style of the previous Batman: The Animated Series to match the cleaner, crisper style of Superman: The Animated Series. The result was The New Batman Adventures, and the revamp was an overall success. This would later enable crossovers such as "World's Finest", "Knight Time", "The Demon Reborn" and "Girl's Night Out".
After the revamp, every resulting show retained this crisper style, and it became the trademark for the DCAU.
As a result of the revamp, some Batman characters (most notably Scarecrow, Penguin, and Mad Hatter) looked drastically different from their Batman: The Animated Series appearances. However, characters such as Two-Face and Harley Quinn were relatively unchanged.
The Bat-Family went through several changes as a result of the revamp, and due to the events of the new series:
- Batgirl's costume went through a major change, the gray and blue coloring of the Batman: The Animated Series costume being replaced with black and yellow to match her classic comic book design along with scallops on her gloves and inside of her cape became yellow.
- As Dick Grayson became Nightwing, the mantle of Robin went to Tim Drake. The costume for Robin was relatively unchanged, except for the fact that it was smaller to fit Drake and all the green sections on the sleeves and gloves were changed to black, the leggings were changed from green to red and the trunks were changed from red to black.
As for Batman himself, his costume went through a number of changes throughout the remainder of the DCAU:
- In The New Batman Adventures, all color in his costume was replaced by blacks and greys. The yellow ellipse Bat-symbol on his chest was swapped out for the wider (non oval-shaped) Bat insignia, and his belt was also changed with the belt color changed from yellow to pale brown and the capsules were changed to pouches.
- In Batman: Mystery of the Batwoman, highlights were added to the revamped costume and the belt was re-designed.
- In Justice League and Justice League Unlimited, he was given a new costume which incorporated aspects from all previous costumes—the design of the The New Batman Adventures costume, the coloring of the Batman: The Animated Series costume, and the long ears and heeled boots from the Batman Beyond costume.
- The Joker's first redesign for The New Batman Adventures was heavily simplified: the orange in his costume was removed, and he was slimmed down significantly and given sharper facial features. He lost nearly all color from his features, toning down the green in his hair and removing his signature red lips entirely. In addition, the yellowish whites of his eyes were turned black.
- The Joker was once again redesigned for Batman Beyond: Return of the Joker, keeping the same outfit from The New Batman Adventures but with a face that was a cross between the two previous designs: Some of the color from ‘’The Animated Series’’’ design was restored, as were the now-wine-red lips and the whites of his eyes. Curiously, the irises of his eyes would also be occasionally red. This design would be used in all subsequent DCAU shows, including Justice League and Static Shock.
- Catwoman's costume became all-black, reminiscent of Michelle Pfeiffer's portrayal of the character in Batman Returns, but with large white eyes. Her skin was also made white when in costume and her hair changed from long and blonde to short and black. This was explained by black being her natural color, and she simply dyed her hair blond until she learned the dye company experimented on live animal subjects.
- The Penguin went through a dramatic change, altering his appearance to have a more normal appearance, resembling his classic comic book appearance and less like the deformed portrayal by Danny DeVito in Batman Returns. This included giving him normal human hands, rather than three-fingered flippers.
- The Scarecrow went through perhaps the most dramatic change, completely altering his costume. Instead of resembling an ordinary scarecrow, Crane’s new grim attire was reminiscent of a Southern preacher, with a wide-brimmed hat and long black trenchcoat. The scarecrow mask became less like burlap and more like the leathery face of a corpse, complete with irregular teeth. He also wore a noose around the neck, and he was given long black hair. Additionally, The Scarecrow now used a large wooden staff as his weapon of choice, in addition to his fear toxin. His costume change was the result of his fright upon seeing an alien group known as The Kraang and wanting to look scarier.
- Mr. Freeze’s suit became simplified yet more intimidating, with a taller stature and made from black metal. His goggles were also removed, making his very eyes red instead, with black where the whites would normally be. As the result of his condition causing his body to wither away, Freeze's head was now attached to a spider-like robot, which resided in the chest cavity of the suit.
- The Riddler altered his costume significantly, replacing the green and purple suit and tie from before with a gaudier, bright green bodysuit bearing a single purple question mark on the chest. He no longer wore a mask, had dark circles under his eyes and became bald under his bowler hat.
- Poison Ivy became more plant-like, with a slight greenish hue to her now-white skin and dark green lips that appeared almost black depending on the lighting. Her hair became less wavy and a darker shade of red, while her new costume became the same green-black as her lips, discarding the original's tights and becoming less leafy.
- Killer Croc's skin was changed from gray to olive green, and lost the bumps on his scalp, shoulders and forearms. He also had broader shoulders with a leaner waist, and his pants were changed from blue to dark gray. His face became less skull-like, with different face and teeth and the spikes on his body almost disappeared.
- The Mad Hatter was redesigned to look more like Sir John Tenniel's illustrations of the original Mad Hatter from Alice's Adventures in Wonderland. To this end, the Mad Hatter was given less normal proportion, becoming drastically shorter and smaller, with a more pronounced overbite and sharper nose. His hair was also changed from blond to white, and his skin also became paler. His outfit's colors changed altogether, with the blue overcoat and purple bow tie being changed to dark green and olive, respectively - a color change which extended to his top hat.
- Bane became more physically imposing, and gained an entirely new mask: This version lacked the original's nose hole and most of its white markings (save for those around the eyes), and had small metal studs around the mouth hole. He also had a spiked collar of some kind, and the tubes of the Venom pump were changed from white to red.
- Baby-Doll's cartoon-like features were greatly simplified and normalized: The oversized blue eyes became more proportional and lost their large blue irises, while her lips became black. The curls of her hair were simplified as well, while her purple dress was changed to pink with white trim.
- Two-Face, Harley Quinn, Ra's al Ghul, Talia, Clayface, Harvey Bullock, and Rupert Thorne were left relatively unchanged, mostly updating their character models to match the new streamlined style.
