A character that goes through a change and is well developed in a story is most often referred to as a complex character. Here's why:
1. Complex Character: This type of character is multidimensional, showing various traits, emotions, and behaviors throughout the story. They undergo significant changes, growth, or transformation as the plot unfolds, making them more realistic and engaging for the audience.
2. Example: An example of a complex character is Ebenezer Scrooge from Charles Dickens' "A Christmas Carol." At the beginning of the story, Scrooge is portrayed as a cold-hearted and selfish person. However, through encounters with spirits and self-reflection, he undergoes a profound transformation, becoming generous and compassionate by the end of the tale.
In conclusion, a character that is well developed and undergoes a change in a story is often referred to as a complex character due to their depth, evolution, and complexity throughout the narrative.
