The sidekick (and why they can’t be “just” a sidekick)

A sidekick can be a stereotype, cliché, stock character, and/or archetype—depending on how much depth you give them. But in most modern fiction, a sidekick who sticks around needs to feel like a real person.

A strong sidekick is usually a secondary character who:

• travels with the protagonist (physically or emotionally)

• supports the protagonist

• adds pressure, contrast, or complication

What makes a sidekick work

Even though they’re secondary, they should still have:

• their own motivations

• their own goals

• their own conflicts that are separate from the protagonist’s.

They should also contrast the protagonist in meaningful ways—personality, skills, values, risk tolerance, social power, or emotional style. If they’re too similar, they won’t add tension or texture to scenes.

Give the sidekick an arc (and possibly a subplot)

Your sidekick should change over the story. Their character arc should complement the protagonist’s arc—either by reinforcing the theme or challenging it.

Many sidekicks also benefit from a B plot (subplot), such as:

• a relationship they’re trying to repair

• a secret they’re hiding

• a personal ambition that conflicts with the main quest

Sidekicks create emotional growth

A sidekick can be a vehicle for emotional growth when there’s friendly conflict. They can challenge the protagonist’s beliefs, call out their blind spots, or force hard choices—making the story richer.

Sidekicks can complicate the plot, but they also make it more human and more memorable.
