Pick an OC type, a SOUL trait, a species look, an attack pattern and an area, and this Undertale OC maker draws your monster or human in a simple indie RPG style. The profile adds a name, a personality, a battle card with LV, HP, ATK and DEF, two ACT options, how to spare them, a check line and a peaceful backstory.
How to make an Undertale OC
1. Type an idea, like "a snail monster who runs a tiny bakery", or leave it empty.
2. Choose an OC type, SOUL trait, species look, attack pattern and area.
3. Press Make my OC to get the drawing and the profile.
4. Download, copy, or regenerate for another version.
SOUL traits and colours
Every human SOUL has a trait and a colour: Determination is red, Bravery orange, Justice yellow, Kindness green, Patience light blue, Integrity blue and Perseverance purple. Even for a monster OC, the trait you pick shapes their personality and the way they act in a battle.
Battle card and mercy
Fans love giving their OC battle details. The profile lists LV, HP, ATK and DEF, two ACT options like Compliment or Joke, the bullet pattern they use, and what you have to do to spare them. Every story is peaceful: the right ACT always leads to mercy.
Fan-made and original
Your OC is new, never a copy of a character from the game, and the tool uses no official art. Each profile ends with a fan-made note, not affiliated with Toby Fox.
Questions
What is an Undertale OC?
An original character for the Undertale world: a new monster or human with their own look, SOUL trait, battle style and story.
Does it give my OC stats?
Yes. The battle card lists LV, HP, ATK and DEF, plus ACT options, an attack pattern and how to spare them.
Can I make a skeleton or a boss monster?
Yes. Both are in the OC type menu, along with monster, human and ghost.
Is this an official Undertale tool?
No. It is a fan tool, and your OC is fan-made and not affiliated with Toby Fox.
Is it pixel art?
The drawing is a simple cartoon with a light pixel-art feel and clean outlines, close to how fans draw for the game.
Can my OC be a villain?
They can start as a tough opponent, but every story ends with mercy. That keeps it true to a pacifist run.
