There may also be other characters such as Benjamin's love interests who are affected by his unique situation and the way he ages.
The main character is Benjamin Button himself. There are also his family members like his father.
In the 'Benjamin Button Short Story', Benjamin Button is clearly the central character. His entire life, from being born as an old - looking baby and aging backwards, is the focus of the story. His father is a significant character as well. His father's reactions and decisions regarding Benjamin, from the initial shock at his appearance to trying to figure out how to raise him, are an important part of the narrative. Additionally, there could be other characters like his mother, though perhaps not as fully developed as Benjamin and his father. And as Benjamin grows (or rather, gets younger), he may encounter various love interests whose relationships with him are shaped by his unusual aging process.
