What should an OC template include?

Eight fields cover everything that matters: name, age & appearance, personality (2 strengths + 1 flaw minimum), voice/speech style, backstory event, goal, weakness, and key relationships. Everything else is decoration.

How do I make an OC that isn't boring?

Build them around a contradiction — a kind healer who can't stand being thanked, a knight sworn to silence with too many opinions. Flaws and gaps create scenes; a perfect character creates nothing.

What's the most common OC mistake?

Overloading: strongest powers + tragic past + mysterious heritage + secretly royal. Every trait you add makes the character harder to actually use. Add one, remove one.

How can I test my OC?

Make them talk. Write three lines — a greeting, them angry, them embarrassed. If you can't hear their voice, the sheet isn't done. Or register them in an AI roleplay like ISEKAI ZERO and have an actual conversation with them.

Most OC templates fail the same way: fifty fields about blood type and favorite food, zero fields that make the character do anything. This is the short version that works — a copy-paste character sheet, a 5-step method, and a way to stress-test the result by making your OC actually talk.

The OC template (copy this)

NAME:
AGE / APPEARANCE:   (3 distinctive traits max)
PERSONALITY:        (2 strengths + at least 1 real flaw)
VOICE:              (how they talk — formal? blunt? sarcastic? verbal tics?)
BACKSTORY EVENT:    (ONE event that explains who they are now)
GOAL:               (what they want — this is why they act)
WEAKNESS:           (physical or emotional — what can stop them)
RELATIONSHIPS:      (how they treat friends / strangers / enemies)

Why these eight and nothing else: goal makes the character move, weakness makes scenes possible, voice makes them feel alive on the page. The other fifty fields on mega-templates are trivia you'll never use.

How to make an OC in 5 steps

One-line concept first. Before any details: "A healer who loves helping people but bolts before anyone can thank her." If the one-liner has a contradiction in it, the character already works.
Fill the sheet above. Resist the urge to add fields.
Cut the overload. The classic mistake is stacking: max power + tragic past + mysterious + secretly royal. Each addition makes the OC harder to write. One in, one out.
Write three lines of dialogue. A greeting. Them angry. Them embarrassed. Can't hear their voice? The voice field needs another pass.
Run them. Characters get finished by being used, not designed. Put them in a scene and watch where the sheet breaks.

Character sheet vs. OC template vs. reference sheet

Quick terminology: an OC template and a character sheet are the same thing in fandom use (TTRPG character sheets add game stats on top). A reference sheet ("ref sheet") is the art version — a drawing showing the design from several angles for artists. This page is the writing one.

Step 5, the easy way: make your OC talk with AI

The fastest way to find the holes in a character sheet is a conversation. In ISEKAI ZERO you can register your OC's sheet and they'll speak, act, and react in character — in an actual storyline, not a vacuum:

Drop your OC into fantasy, school, or modern settings and see how they handle scenes you didn't script
The AI remembers events, so your OC's relationships accumulate the way you imagined them
Scenes generate art and music — your OC stops being text on a sheet and becomes someone you can see
Free to play (free Mana daily, ads for extra), and if you publish a storyline built around your OC, you earn a 25% profit share when others play it

Designing a character is fun. Meeting them is better.
