📋 Prompt
You are a comic book creator and character designer who has developed characters for indie and major publishers.
Character concept: [hero/villain/sidekick/morally complex]
Genre: [superhero/noir/sci-fi/fantasy/horror/slice-of-life]
Art style: [Marvel realist/manga/indie/Moebius/Kirby]
Purpose: [comic book/game/illustration/writing project]
Create a complete character design package:
1. OVERVIEW: Name, origin, one-sentence essence
2. VISUAL DESCRIPTION: Body type, height, facial features, costume with hex colour codes, materials, details, and the SIGNATURE ELEMENT — what makes them unmistakable in black silhouette
3. BACKSTORY (300 words): Origin, formative event, what drives them
4. PERSONALITY AND VOICE: 3 core traits + 1 fatal flaw; how they speak (3 example lines); what they want vs. what they need
5. POWERS/SKILLS: Primary ability, secondary skills, limitation/weakness
6. VISUAL REFERENCES: 3 existing characters they draw from (and exactly how they differ)
7. AI IMAGE PROMPTS (3): Character portrait, action pose, civilian/casual version

CHARACTER: RESONANCE
ESSENCE: A former sound engineer who absorbed a catastrophic sonic weapon and now controls vibration and sound — while slowly going deaf from using the power.
VISUAL:
Height: 5'10", lean and angular — built like a distance runner
Face: Sharp jaw, permanent slight grimace from tinnitus, asymmetric cyberpunk hearing aids built into the mask (left ear, visible, deliberate design choice)
Costume: Deep charcoal armour (#1c1c2e) with vibration-dampening panels in matte gunmetal (#4a4a5a); copper circuit-line detail (#b87333) that glows faintly when power is active
SIGNATURE: Glowing copper circuit lines on both forearms — unmistakable in silhouette
BACKSTORY:
Jordan Mace was a live concert sound engineer who lived for the way perfect audio transforms a room. On the night of a stadium concert, a weaponised sonic device detonated, killing 23 people. Jordan survived having absorbed most of the blast through the mixing board. They woke three weeks later able to feel every vibration in the environment — and redirect, amplify, or silence sound within 200 metres. The cost: hearing deteriorates 5% per year. Every heavy use of the power accelerates the loss.
DIALOGUE:
'I can hear your heartbeat. It's faster than you're pretending to be.'
'Sound doesn't lie. People do.'
'I stopped listening to music the day I lost the high frequencies. Now I feel the bass and try to remember what the rest sounded like.'

💡 Pro Tips
Best model for this prompt
Claude
Claude (Opus 4 / Sonnet 4)
Silhouette test is the most important design check — if you can't identify your character in black silhouette alone, the design needs a stronger signature element
The fatal flaw must be connected to the power or backstory — a general bad temper is generic; a flaw that grows from the origin is design
Write dialogue before description — voice reveals character more than any visual detail
Hex codes for costume colours are worth specifying for AI prompts — colour is the fastest way to build recognition across scenes
Too powerful with no meaningful limitation — powers without costs aren't dramatically interesting
Generic backstory ('parents died, wants revenge') — the formative event should create the specific psychological wound
Over-designed costume — the most iconic characters have simple strong silhouettes, not 47 details
Inconsistent power logic — define the rules and stick to them; inconsistency breaks reader trust
- How do I make a character feel original?Combine two unexpected things — competence and emotional fragility; a villain right about the problem but wrong about the solution. Start with a specific human contradiction, then build the concept around it.
- What makes a good fatal flaw?A strength taken too far, or a wound that drives bad decisions. Pride becomes arrogance. Loyalty becomes blind obedience. The origin story wound should directly generate the flaw.
- Best model?Claude builds psychologically consistent characters, writes distinctive dialogue, and maintains thematic coherence between backstory, power, and flaw.
- Best AI image tool for character sheets?Midjourney for cinematic portraits. DALL-E 3 for consistent appearance across multiple poses. Use Midjourney's Character Reference (--cref) for consistency across a series.
