Welcome to Reedsy's sidekick name generator
The sidekick is the most underestimated character in fiction. They're often where the emotional truth of a story actually lives — the person the hero talks to when they can't talk to anyone else, the character who gets to be funny or scared or openly confused in ways the protagonist can't afford to be. A sidekick's name needs to reflect all of that: it should feel approachable, often warm, and just a little distinct from the hero's register without overshadowing it.
Our generator does, because you tell it. Give it your sidekick's personality, their genre, their world, and anything else that shapes who they are — and it returns ten names, each with a short explanation of why it fits the character you've described.
How to use this name generator
Personality matters especially for sidekick characters, because the sidekick's function in the story is often defined by their temperament. You can use the personality dropdown to set the tone.
Select gender and book genre, then use Setting or world to anchor the results in your specific context. "The Shire," "1920s Harlem," and "a generation ship three centuries into a deep-space voyage" will each pull the names in different directions.
The Additional details field is particularly important for sidekick characters: specify their relationship to the protagonist, their cultural background, any naming conventions in your world, and — crucially — the protagonist's name. The sidekick's name often works best when it creates a natural pairing or contrast with the hero's, and the generator can calibrate for that if you tell it what the hero is called.
Each generation returns ten names with reasoning. Select the keepers and run up to four generations per session.
So you want a good sidekick name?
Getting a sidekick's name right means understanding that the sidekick exists in relationship to another character.
A few things worth knowing as you write:
- The sidekick's name often signals accessibility. Where hero names can carry mythic or aspirational weight, sidekick names frequently do the opposite: they're grounded, familiar, sometimes even slightly comic. This isn't accidental. The sidekick is often the reader's emotional proxy — the character who asks the questions the reader is asking, who expresses the fear the hero is suppressing.
- Names can carry class and social register. In many stories, the gap between hero and sidekick is partly a gap in social position — one aristocratic, one common; one educated, one street-smart. Names can reflect that gap, and doing so deliberately is more interesting than arriving at it by accident. The additional details field is a good place to flag if this dynamic is part of your story!
- Sidekick names in genre fiction often carry affectionate weight. Samwise, Piglet, Horatio, and Mercutio tend to feel warm and slightly individual, names you could imagine being used with genuine affection by someone who loves them. That quality is worth aiming for deliberately. It's what separates a memorable sidekick from a functional one.
- Be careful with names that are purely functional. A sidekick called something generic and genre-adjacent — Flint, Rook, Chase — can read as a placeholder rather than a person. Unless the name is doing something specific and intentional, sidekicks tend to benefit from names that feel slightly particular: a name someone chose for this specific person, rather than a name that comes with the archetype.
- Read the literature. The sidekick tradition has produced some of fiction's most beloved characters, and their names are worth studying. Tolkien's Samwise Gamgee is a masterclass in how a humble name can become heroic through the story it's attached to. Look at how Terry Pratchett names his supporting characters throughout the Discworld series — wit and specificity in every choice. Read Patrick O'Brian's Master and Commander for the Aubrey/Maturin pairing, one of the great studies in how two contrasting names can define a relationship.
A note on our use of AI
We built this tool for writers, which means we thought carefully about what AI should and shouldn't do here. The generator uses AI to produce sidekick names that better fit your character's specific context and needs — personality, gender, genre, setting, and their relationship to your protagonist — while explaining its reasoning for each one.
Here's what it won't do for you: it won't write your story, name your character, or make creative decisions for you. It simply generates options for you.
More importantly, your inputs are not (and will never be) used to train any AI models. Treat whatever comes out as raw material: a starting point that belongs entirely to you. Every result is yours!
