" I take inspirations from newspaper strip cartoonists who look for ways of expanding their characters’ worlds once they have established the initial concept of their strips. "
- Paul Dini

In simple terms, the quote suggests that successful cartoonists continually expand their characters' universes after creating them, much like how an artist builds on a solid foundation by adding more dimensions and depth to their work. This process involves finding new ways to enrich established ideas and bring fresh life to familiar concepts.

The deeper meaning of this statement lies in the importance of creativity and adaptability when developing stories or characters over time. It highlights that merely establishing a character is just the beginning; what truly brings them alive and resonates with audiences is the ongoing exploration and evolution of their world. This approach encourages creators to think beyond the initial concept, constantly seeking new angles and contexts in which their characters can thrive and develop, thereby keeping their narratives engaging and dynamic.

Paul Dini, the author of this quote, is a renowned American screenwriter, producer, and comic book writer best known for his work on beloved television series such as "Batman: The Animated Series" and its spin-offs. His contributions to expanding character universes have been pivotal in redefining how superhero stories are told, emphasizing complex narratives and nuanced character development.
