How to Write Believable Fictional Aliases

A great alias does two jobs at once: it hides the character and reveals them. The best fictional street names hint at a backstory — The Gardener tends something secret, Iron Ledger never forgives a debt. When you invent an alias, ask what the character wants the world to believe about them, then twist it.

Keep the name short enough to shout across a room and strange enough to remember after one hearing. Test it in dialogue: if it sounds natural when another character says it in anger, it works.

• Give it history: the best aliases sound earned, not chosen — a scar, a habit, or a job gone wrong.
• Match the role: couriers get quick names, bosses get heavy ones, informants get slippery ones.
• Stay fictional: avoid anything resembling real people or real criminal slang; invented is always safer and more creative.
• Say it out loud: rhythm matters — Ghost hits harder than a long, clumsy title ever could.
