I'm not sure specifically as I haven't read the book in detail. But usually in stories about love, there could be a passionate lover, someone who is deeply in love and whose actions are driven by that love.
It's possible that there is a protagonist who experiences the most intense form of'mad love'. This character could be on a journey of self - realization through their experiences of love. There could also be a love interest, someone who is the object of the'mad love' and who has their own personality and influence on the story.
There might be a character who is initially resistant to love but then gets caught up in the'mad love' situation. Maybe there's also a friend character who provides advice or a different perspective on the love affairs in the stories. Without reading the book, it's hard to be certain about the exact notable characters.
The Joker might also be an important character even if not as directly focused as Batman and Harley Quinn in some of these stories. His influence on Harley Quinn and his general role as a major villain in the Batman universe means his presence is still felt and can impact the events in 'batman mad love and other stories'.
There's Max Rockatansky, of course. He's the central figure, a former cop turned post - apocalyptic wanderer. There are also the War Boys, a group of fanatical followers of Immortan Joe. They are often seen as both villains and victims. And Nux, a War Boy who has an interesting character arc, is also quite notable in the novels.
In 'The Lottery', Tessie Hutchinson is a notable character. She becomes the victim of the lottery, and her protests at the end highlight the horror of the situation.
There is the narrator in many of the stories. His perspective is crucial as he guides us through the strange events. Also, in the story of 'The Aleph' itself, Carlos Argentino Daneri is a notable character. He is the owner of the house where the aleph is supposedly located.
Max is the most notable character. He is a lone wanderer, a survivor who has seen the worst of this post - apocalyptic world. He is tough and resourceful, always looking out for himself but also having a sense of justice deep down.
The old man in the story by the river is also a character that stands out. He has a lot of wisdom that he imparts, but also a sad backstory that is gradually revealed throughout the story. His presence in the story adds depth and a sense of melancholy as he reflects on his life and the changes in the world around him.
I'm not entirely sure without reading the book specifically, but likely there is the variable man himself. He's probably a central character whose variability sets the tone for the stories he's in.
Big Blonde is surely a notable character. She is likely the central figure in at least some of the stories, and her experiences are probably what drive the plot in those cases.
Well, since it's a friend of Kafka, that friend would be a notable character. Maybe it's someone who has a deep understanding of Kafka or is influenced by him in some way. There could also be other characters who are in contrast to this friend, like those who don't understand Kafka's ideas at all.
I'm not sure specifically as I haven't read it in detail, but there might be a protagonist who is at the center of the story about 'half a life'. This character could be someone who has experienced a major change or turning point in their life.
