The Sidekick’s Guide to Screenwriting: Crafting Memorable Secondaries

From Comic Relief to Co‑Hero: The Evolution of the SidekickThe sidekick has long been a fixture of storytelling — a character who supports the protagonist, supplies contrast, and often guides the audience’s emotional response. Once relegated to comic relief or a convenient plot device, sidekicks have transformed over the past century into complex, autonomous figures who share heroism, moral weight, and narrative agency with their leads. This article traces that evolution across media, examines the forces driving change, and explores what modern sidekicks reveal about culture, storytelling, and the nature of partnership.


A brief origin: sidekicks in myth and folklore

Sidekicks are not a modern invention. Ancient myths and folktales often include companions who support, test, or betray heroes. Think of Enkidu beside Gilgamesh, or Hera’s attendants aiding Greek gods. These figures established early templates: loyal companion, foil, moral compass, or obstacle. Their purpose was practical as well as narrative — they enabled exposition, revealed the hero’s character, and made long journeys or quests believable.


The early modern era: serialized fiction and pulp heroes

In the 19th and early 20th centuries, serialized fiction and pulp magazines codified the sidekick type as readers demanded recurring characters. Gothic and adventure serials gave us assistants like Dr. Watson, whose dual role as chronicler and confidant set a durable pattern. Watson’s everyman voice made Sherlock Holmes’s intellect more comprehensible and accessible — a living audience surrogate.

Pulp heroes and radio serials leaned heavily on sidekicks for exposition, comic relief, and to demonstrate the hero’s leadership. The sidekick was often younger, less competent, and reliably loyal — think Robin to Batman or Tonto to the Lone Ranger. These sidekicks served genre expectations and social norms: in an era when heroes projected idealized masculinity, sidekicks provided vulnerability, warmth, or humour.


Comic books and the institutionalized sidekick

The Golden Age of comics (late 1930s–1950s) institutionalized the sidekick, particularly in American superhero stories. Robin (introduced 1940) was notable for being a teen sidekick whose presence softened Batman’s brooding persona and made the stories marketable to younger readers. Sidekicks in comics became a merchandising opportunity as well as a narrative fixture: youth heroes, partners, or junior versions of the hero reinforced brand loyalty and widened the audience.

However, comics also exposed the limitations of the trope. Sidekicks were sometimes treated as disposable (the trope of “fridging” where a character—often female or younger—was harmed to motivate the hero), or placed in permanent subordinate roles. Over time, readers and writers pushed back, seeking more depth and agency for those secondary figures.


Film and television: changing functions and visibility

As film and television storytelling matured, sidekicks evolved in tandem. Early cinema used broad archetypes: the buffoon, the faithful servant, the plucky assistant. Television, with its episodic structure, allowed sidekicks to develop slowly over seasons. Sitcoms and dramas used them either for comedic beats (Samwise-like best friends) or as narrative foils.

Important changes came with shifts in cultural attitudes. As audiences grew more sophisticated and interested in character psychology, sidekicks gained complexity. They stopped existing merely to highlight a hero and began to have their own arcs, backstories, and moral dilemmas. Examples include Dr. John Watson’s modern reinterpretations as an equal partner rather than merely a chronicler, or Sulu and Uhura in Star Trek becoming more central as cultural representation demands increased.


Video games and interactive media: sidekicks as gameplay partners

The rise of video games introduced a mechanical dimension to sidekicks. Companions in games can influence gameplay — providing support in combat, puzzle-solving, or narrative choices. They can also be customizable, giving players a sense of agency in the partnership.

Notable shifts include companions who are essential to both story and systems: Alyx Vance in Half-Life 2 functions as an emotional anchor and gameplay ally; Ellie in The Last of Us evolves from a dependent to a co-equal protagonist; and NPC companions in role-playing games (e.g., Mass Effect, Dragon Age) can be romanced, argued with, or shaped by player choices. The interactive medium raises questions about autonomy: are sidekicks scripted props, or co-authors of the player’s journey?


The rise of the co-hero: shared protagonism

Contemporary storytelling increasingly favors co-heroes—paired leads whose arcs interlock. This shift stems from several forces:

  • Audience desire for representation and complexity: Audiences want characters who reflect varied identities and who grow across the narrative.
  • Narrative realism: Partnerships mirror real-world collaboration; conflicts, compromises, and mutual influence feel authentic.
  • Commercial storytelling: Franchises diversify characters to appeal to broader demographics and avoid overreliance on a single star.

Examples of co-hero dynamics include:

  • Sherlock Holmes adaptations (e.g., BBC’s Sherlock) which reframes Watson as a professional equal and emotional counterpart.
  • The Marvel Cinematic Universe’s duo dynamics (e.g., Tony Stark and Steve Rogers’ conflicts) that distribute moral agency and screen-time.
  • Television duos like Buffy and Willow, or The Mandalorian and Grogu, where emotional stakes and heroic tasks are shared.

Sidekicks and representation: expanding who gets to be the support

Historically, many sidekicks reflected dominant cultural power structures: often white, male, and secondary. Over recent decades, creators have intentionally diversified sidekicks by gender, race, sexual orientation, age, and neurodiversity. That diversification challenges assumptions about who can play support roles and how those roles function.

When sidekicks come from marginalized backgrounds, their perspective enriches the narrative and provides critique: they are not only there to make the hero look better but to reflect overlooked histories and moral complexities. This change also allows sidekicks to step into co-hero roles or lead their own stories, further decentralizing the protagonist-centric model.


Deconstructing tropes: what modern writers avoid

Modern writers tend to avoid several problematic sidekick tropes:

  • Fridging: harming or killing side characters (often female) solely to motivate the protagonist.
  • Tokenism: giving a character superficial traits without depth.
  • Permanent infantilization: keeping the sidekick forever inexperienced or subordinate for convenience.

Instead, contemporary stories favor reciprocal relationships, growth arcs, and consequential choices for sidekicks. Writers create believable tensions: jealousy, ideological differences, and competing goals that add narrative richness.


The mechanics of a good sidekick today

Effective modern sidekicks usually share these traits:

  • Distinct agency: goals, fears, and choices independent of the protagonist.
  • Complementary skills: abilities that make them necessary but not redundant.
  • Emotional resonance: backstory and vulnerability that invite audience investment.
  • Capacity for growth: a clear arc that can converge, diverge, or merge with the hero’s arc.

Crafting such a sidekick involves treating them as a person, not a function. They should be capable of surprising the audience and the protagonist.


Case studies

  • Samwise Gamgee (The Lord of the Rings): Begins as loyal gardener and becomes moral anchor and hero in his own right. His courage and humility reframe heroism as service and endurance.
  • Robin/Nightwing (Batman franchise): Robin’s evolution into Nightwing shows a sidekick’s path to autonomy and leadership, challenging the notion of permanent subordination.
  • Dr. John Watson (modern adaptations): Reimagined as a partner, professional equal, and emotional touchstone — his role underscores narrative balance rather than simple exposition.
  • Ellie (The Last of Us): Transitions from a protected companion to co-protagonist with agency, moral complexity, and central narrative weight.
  • Chewbacca (Star Wars): From loyal sidekick to military commander and symbolic co-hero, Chewbacca’s loyalty is matched by demonstrated competence and sacrifice.

Why the evolution matters

This shift reflects broader cultural and artistic maturation. Sidekicks evolving into co-heroes indicates:

  • A move toward more egalitarian narratives where partnerships are reciprocal.
  • Recognition that supporting characters enrich worldbuilding and thematic depth.
  • An appetite for ensemble storytelling that mirrors complex social relationships.

It also affects audience identification: viewers and players can invest in multiple perspectives, making stories more immersive and relatable.


Looking forward: future directions

Expect further evolution along these lines:

  • Ensemble-driven narratives where protagonist/sidekick distinctions blur.
  • Interactive sidekicks whose autonomy adapts to player choices and AI-driven behavior.
  • Continued diversification and subversion of old tropes, with sidekicks originating from nontraditional backgrounds and serving as primary lenses for storytelling.

As media converge and audiences demand nuance, the sidekick’s role will likely expand into collaborative heroism, where the lines between “hero” and “support” are porous and dynamic.


Conclusion

The sidekick has traveled from a simple storytelling utility to a fully fleshed narrative partner. Modern sidekicks often carry moral weight, narrative agency, and cultural significance that rival — and sometimes surpass — the traditional hero. Their evolution mirrors societal shifts toward valuing partnership, diversity, and shared protagonism, making them among the most interesting figures in contemporary storytelling.
