Have you ever dreamed of having a character that is entirely yours?
A character with their own personality, their own story, and their own unique charm.
That’s what we call an OC (Original Character) — your one-of-a-kind creation.
An OC is more than just an image or a name.
They are a reflection of your inner world, the embodiment of your imagination.
They can take any form: a hero traveling across the stars, a magical girl in the heart of the city, a mysterious being from another dimension, or even an abstract concept with no fixed shape.
An OC is the special language you use to share your creativity with the world.
Whether it’s a fully fleshed-out character with a detailed backstory, or a simple design to express a feeling, it can be called an OC.
What Does Your OC Need? – Building the Soul and the Shell
A complete OC usually includes several core elements:
1. Character Profile – Their “ID Card”
- Core: name, age, gender, physical features, personality, occu?ion/role, special abilities.
- Depth: unique quirks, catchphrases, hobbies, relationships (family, friends, rivals).
- Visuals: detailed illustrations, reference sheets, outfits, signature accessories.
2. Backstory – Their “Life Journey”
- Origin: background, childhood, key turning points.
- Worldbuilding: what kind of world do they live in? What rules or culture define it?
- Goals & Conflicts: what do they dream of? What challenges do they face? What values guide them?
How to Imagine Your First OC? – Embark on Your Creative Journey
Creating an OC isn’t difficult. At its core, it’s simply “turning a blurry idea in your head into something tangible.” Here are some ways to start:
- From a theme
Example: with “autumn” as a theme → a maple-leaf shrine maiden, a chestnut-delivering fairy, or a wandering poet in the autumn wind.
2. From a world
If you’ve created a fantasy setting, think about your OC’s role: a knight? a mage? a traveling merchant?
3. From an emotion
Embody a feeling or experience: a lonely night watcher, a spirit of light carrying hope.
4. From visual elements
Begin with a striking design (a mechanical arm, a fox mask) and expand the story around it.
💡 Tip: You don’t need to finish everything at once. Start with a core idea and add details over time. Browse others’ creations for inspiration (but avoid copying!).
