Main characters

 * The Batman/Bruce Wayne: Under the cape and cowl can be found a younger Bruce Wayne in his 20s. The media is more likely to catch him courtside at a Gotham Gators game or strapping on a helmet to drive his own racecar for a charity than in front of City Hall cutting a ribbon. But don't confuse the swinging bachelor persona for the real Bruce – he's intense, driven and completely focused on his life's mission to serve as the Dark Knight. Aided by technology he's secretly developed – including the operating system known as the Bat-Wave – and driven by the childhood memory of the loss of his parents, Batman takes to the streets in order to bring Gotham's new breed of super villains to justice
 * Robin/Dick Grayson: After the death of Dick's parents, Bruce Wayne took the boy under his wing. To bring justice to the criminal’s responsible for his parents' death, Dick joined The Batman's side as Robin. A highly skilled and energetic acrobat, Robin has become an asset to the fight alongside The Batman and Batgirl.
 * Batgirl/Barbara Gorden: Batgirl, real name Barbara Gordon, the teenage daughter of Gotham's Commissioner Gordon, is a strong-willed, stubborn teen with an ironic wit. Inspired by her first contact with The Batman, she dons the cape and cowl to become Batgirl to help save her father from the hands of former friend and now villain - Poison Ivy. She eventually gains Batman's trust and he reveals his secret identity to her

Justice League

 * Superman(George Newbern):Bumbling Daily Planet reporter Clark Kent is the Man of Steel: Superman. An alien from a destroyed planet called Krypton, he has superpowers from strength, speed to flight thanks to the yellow sun. As he went to Gotham to present a check from Metropolis, Metallo attacked him and this was when he first met Batman. Wanting nothing to do with another superhero, nor the new Justice League, he ended up fighting three of Batman's rogues before falling under the control of his foe Lex Luthor. After a fight against Batman, which spanned from Metropolis to Gotham, Superman was eventually freed from the control and stopped Luthor's evil plot. Later, he found a trust with Batman and decided to join the League after all

 * Firefly: Garfield Lynns is a work-for-hire-arsonist who uses laser-technology to commit his crimes. In an episode, he is hired to take down Gothcorp so that they could not fund the children's hospital, but he gets defeated by Batman before he can do so.
 * Killer Croc:Waylon Jones was an ex-military who was rumored to be a genetic experiment gone awry, that he deals with the wrong kind of voodoo magic in the swamps, he is simply a circus freak (it is never explained which, if any, story is true. Of course, there were hints that he was actually born with a mutation that gave him the appearance of half-man, half-reptile), Killer Croc is a virtual powerhouse and has two pet crocodiles to do his bidding. With the strength of a crocodile (and a tail to boot), Croc is able to chomp and swim his way around Gotham. In this version, Killer Croc is even more reptilian than past versions and has a tail. He appears to be much stronger than Batman and much like a crocodile, he's able to stay underwater for long periods of time.
 * Ragdoll(Jeff Bennett):is a master thief and triple-jointed contortionist, capable of bending his body in all sorts of impossible ways. Able to bend himself in every imaginable (and even some unimaginable) positions, Ragdoll is a formidable opponent for The Batman, but an even bigger adversary of Catwoman. While Catwoman's interests are merely in cat-related fare, Ragdoll's interests lay wherever the money is. To Catwoman's dismay, this is also in rare cat-items: vintage animation cells, priceless artifacts and the main jewel of their battle, two 'Cat's Eyes' emeralds, hidden in a Gotham Clock Tower by a mobster in the 1930s. Though never found, it was enough to pique the interest of Ragdoll and Catwoman, falling into a trap set by The Batman. After a lengthy and spectacular battle (during which Ragdoll found his prize wedged between two gears he twisted through), Ragdoll went to Arkham empty handed, Catwoman back home and The Batman (and Bruce Wayne) with two newly found emeralds.
 * Clayface:Basil Karlo is a third-rate actor. When he's rejected for a dog food commercial for "not having the right look", Basil finds out about Waynetech's research into Clayface, and steals the "Clayface-formula" from their labs. He drinks it and gains shape-shifting abilities, but when he is again rejected for the commercial, he attacks the audition panel and becomes a wanted criminal.
