Start the character card with function and goal
Oh Story’s supporting-character card asks for function, relationship, core traits, a memorable feature and an exit. Add “What do they want for themselves?” to keep the character from becoming a source of clues or praise.
These characters belong to an original story: a mechanic needs to finish a team’s bike order before rent is due.
| Item | Record |
|---|---|
| Tao, the apprentice | Main-plot function: Spots a delivery gap and can handle repairs; Personal goal: Wants responsibility for a complete bike; Recognizable behavior: Writes each test result on the back of a red tag; Where they go next: Asks to take charge of student bikes |
| Xu, the neighboring shop owner | Main-plot function: Offers a temporary bench on negotiated terms; Personal goal: Needs room for her own busy season; Recognizable behavior: Writes agreements on the back of a receipt; Where they go next: Reclaims the bench but remains a possible partner |
| Min, the team captain | Main-plot function: Sets the team’s receiving priority; Luo performs the final repair check before bikes become available; Personal goal: Needs safe bikes for tomorrow’s race; Recognizable behavior: Tests every brake rather than accepting assurances; Where they go next: Leaves with the team and later sends feedback |
Function explains the entrance; a personal goal explains refusals and negotiations. Both are necessary.
Use one pressure to reveal different priorities
Fictional scene: at ten at night, six bikes remain unchecked. The protagonist plans to skip dinner and wants everyone to stay.
Tao rolled the third bike to his bench. “I’ll do this one. You give it the final check.”
Xu stayed standing. “I close at eleven. Use the bench. Leave the stock on the shelves.”
Min crossed two spare bikes off tomorrow’s list. “The four race bikes first. Tell me exactly what’s missing.”
All three cooperate on different terms: Tao seeks responsibility, Xu protects her business, Min changes the delivery priority. The protagonist still chooses the repair order and bears the result.
Shared concern does not itself make functions overlap. If there is only repeated reassurance without distinct information or experience, consider combining roles or developing independent aims. Shared care can also be the scene’s purpose, without adding conflict merely to distinguish people.
In this example Luo owns the final repair check, while Min selects which cleared bikes the team receives first. Luo replies: “Four first. Tao handles the basic work; I recheck each bike. The bench until eleven, and no touching the stock.” Xu agrees to that return time. This establishes the work arrangement, not four completed inspections, independent sign-off by Tao, or a returned bench.
Repeat a trait while changing what it costs
Tao’s habit of recording repairs is a recognition cue. At first the mechanic thinks it slows him down; later the notes reveal an omission; finally Tao must take responsibility for his own signed checks. The behavior repeats, but its meaning and cost change.
Do not repeat a catchphrase at every entrance or substitute extravagant appearance for character. Choose one or two stable traits, then expose tension within them: Xu values clear accounts but may waive a fee for a student. Her chosen exception carries more weight than “She was kind underneath.”
Recurring characters should inherit the relationship’s history; ordinary companionship can remain without a new conflict at each entrance. A brief visitor may need only a clear goal and a memorable choice. Give them space proportionate to their function.
Plan departures and repair attention problems
| Item | Record |
|---|---|
| A supporting character suddenly knows every answer | Check: Where the information came from; Repair: Establish a source and a knowledge boundary |
| They control the main story more than the protagonist | Check: Who chooses and pays; Repair: Return the main decision to the protagonist while keeping local choices theirs |
| The cast grows without need | Check: Who performs the same function; Repair: Merge overlapping roles; preserve necessary differences in goals |
| Someone vanishes halfway through | Check: Which promises remain open; Repair: Show completion, failure, handover or a reason for leaving |
At the entrance, answer “Why this person?” At the exit, answer “What happened to their task?” Everyone need not receive a long epilogue, but accidental disappearance leaves a promise unpaid.
FAQ
Does every supporting character need a complete arc?
No. A recurring, consequential character needs developing goals and relationships. A one-scene character may only need a clear choice, trait and departure.
Which character should I cut from an overcrowded cast?
Check duplicated functions and relationships. Merge someone whose removal changes no decision, information or consequence; do not cut the only person able to perform an important action merely because they speak little.
Do it with the skill
Ask story-long-write for a supporting-cast plan only: each person’s function, own goal, disagreement with the protagonist, recognizable behavior and exit. Request suggestions for overlapping roles without drafting chapters.
