Crafting Compelling Sub-characters


In the Science fiction genre, it is not just the protagonists who capture our imagination; it is the worth of side characters that truly bring a new world of fiction to life. From strange engineers innovating new ideas with futuristic gadgets to enigmatic aliens with hidden agendas, side characters play a crucial role in adding depth and complexity to sci-fi narratives. In this article, we delve into the art of creating compelling side characters and explore how they can elevate the storytelling experience in science fiction.

Distinctive Personalities and Motivations:

In addition to being plot devices, side characters must have distinct personalities and motives of their own. Giving them nuance and complexity makes the characters richer in the narrative, whether they are adversaries, allies, or impartial passersby. Think about their histories, aspirations, anxieties, and strategies for overcoming the obstacles of the science fiction setting they live in.


In “Neuromancer” by William Gibson, Molly Millions is a memorable side character with her augmented body and cybernetic enhancements. Her motivations stem from a desire for independence and survival in the gritty, cyberpunk world of the Sprawl.

Diverse Backgrounds and Cultures:

Science fiction frequently features a wide range of creatures, civilizations, and philosophies. Accept this diversity by including supporting characters from different backgrounds. Examine how their opinions and interactions with the main characters are shaped by their cultural norms, traditions, and beliefs. This enhances the world-building and gives more authenticity.


“The Left Hand of Darkness” by Ursula K. Le Guin introduces us to Genly Ai, an envoy from the Ekumen tasked with making contact with the planet Gethen. The inhabitants of Gethen, known as Gethenians, have a unique culture and physiology that challenge Genly’s understanding of gender and society.

Dynamic Relationships and Interactions:

The structure of the story can be greatly influenced by the interactions between the supporting characters and the primary characters. These exchanges, which can involve ardent opponents or dependable allies, can influence story developments and expose novel aspects of character depth. To keep the audience interested, try out various interactions, such as friendship, romantic tension, or mentorship.


In “Hyperion” by Dan Simmons, the relationship between the Consul and his daughter Rachel is a poignant example of dynamic interactions. Their emotional journey, as revealed through flashbacks and memories, adds depth to the narrative and explores themes of love, loss, and redemption.

Unpredictable Arcs and Development:

Side characters ought to develop and alter throughout the narrative rather than stay the same. Their growth gives the story more complexity, whether it is in overcoming obstacles in their lives, facing moral quandaries, or coming to difficult decisions. Subvert assumptions and let side characters develop in unexpected ways to surprise the viewer.


“The Expanse” series by James S.A. Corey features Amos Burton, a mechanic aboard the Rocinante. Amos undergoes significant development throughout the series, grappling with his troubled past and evolving into a complex character with his moral code and sense of loyalty.

Impactful Contributions to the Plot:

Even though they might not always be the main characters, secondary characters’ choices and actions can have a big influence on the story. Every contribution should feel significant and essential to the development of the story, regardless of how big or tiny—whether it is a simple deed of kindness that alters the course of events or a critical piece of knowledge that results in a breakthrough.


Memorable Coincidences and Traits:

Give supporting characters distinctive characteristics, anecdotes, or unusual qualities to help them stick in the minds of viewers. These small things, like a distinguishing physical characteristic, an unusual behavior, or a clever sense of humor, may give even the most unimportant people personality and dimension.


In “Snow Crash” by Neal Stephenson, YT is a skateboard courier with a knack for navigating the chaotic streets of futuristic America. Her fearless attitude, along with her mastery of the Metaverse and her penchant for delivering pizza, make her a memorable and endearing character.

Exploration of Morality and Ethics:

Complex moral and ethical challenges are frequently explored in science fiction. Side characters might challenge the main cast’s opinions and convictions by offering other viewpoints on key topics. You can strengthen the story’s thematic resonance and encourage stimulating conversations by presenting opposing points of view and morally ambiguous situations.


“Foundation” by Isaac Asimov introduces us to Hari Seldon, the creator of psychohistory, a science that predicts the future of large populations. Seldon’s ethical dilemma about whether to reveal the impending fall of the Galactic Empire showcases the moral complexities inherent in shaping the fate of civilizations.


Strong supporting characters for science fiction literature are like the fuel for a jet wing, adding depth and illumination to the story. Writers may enhance their worlds and enthrall audiences with tales that linger long after the last page is read or the credits roll by giving them depth, complexity, and relevance. Therefore, keep in mind to give your supporting characters the attention they merit the next time you go on a cosmic adventure—you never know when they might steal the show.
