In storytelling, a "two-dimensional" character refers to a character who lacks depth and complexity. It is often used to describe a character that is portrayed in a simplistic or shallow manner, with limited personality traits, motivations, or development.
Two-dimensional characters are typically one-dimensional in their portrayal, often representing a single, easily identifiable characteristic or stereotype. They may lack realistic or contradictory qualities that make characters more relatable and human-like. These characters tend to be predictable and do not undergo significant growth or change throughout the story.
In contrast, a well-developed or "three-dimensional" character is more complex, exhibiting a range of emotions, motivations, and behaviors. They are more fully fleshed out and may possess strengths, weaknesses, and internal conflicts. Three-dimensional characters are often more engaging and can add depth and richness to a story.
Creating multi-dimensional characters allows writers to explore different facets of human nature, challenge stereotypes, and provide more nuanced and compelling narratives.
