In addition to the Joker, the Penguin could be an important character. He may have his own interests and power struggles within the criminal world depicted in the graphic novel. Then there's Alfred, Batman's butler. Although he doesn't directly interact with the Joker most of the time, he provides support and advice to Batman, which in turn has an impact on how Batman deals with the Joker. There may also be other detectives or police officers who are part of the story, trying to solve the crimes and stop the Joker's madness.
There's Harley Quinn. She has a complex relationship with the Joker and is often his accomplice. Another important character could be Commissioner Gordon. He's always trying to keep the city in order in the face of the Joker's chaos.
One of the main themes is chaos. The Joker is a character who thrives on creating disorder and anarchy. Another theme could be the nature of insanity. His actions and thought processes in the graphic novel often explore the blurred lines between sanity and madness.
The main character is obviously the Joker. He is the central focus of the story, driving the plot forward with his chaotic and unpredictable actions.
The unique art style in Azzarello's Joker Graphic Novel makes it stand out. The dark and gritty visuals really bring the character of the Joker to life in a new and interesting way. It also delves deeper into the Joker's psyche than some other works, which is a major draw for readers.
Batman is definitely one of the main characters. He is the Joker's nemesis, and their interactions drive a lot of the story.
Harley Quinn is quite interesting. She's caught in the middle between her love for the Joker and her own sense of self. Commissioner Gordon is also important. He's the one who often has to deal with the aftermath of Batman and the Joker's battles and is a symbol of the law in Gotham.
Batman would definitely be a main character. He's the Joker's arch - nemesis, and when the Joker becomes a baby, Batman might be the one who first discovers him. He'd be in a moral dilemma about what to do with this baby version of his greatest enemy.
I'd say Harley Quinn. She has a very unique relationship with the Joker. Her love for him, despite his insanity and abuse, adds a lot of depth to her character. And then there's Robin. His youth and idealism in the face of the Joker's evil present a great contrast. He represents the hope that Gotham can be saved from the likes of the Joker.
