What Is the Undertale OC Maker?
The Undertale OC Maker lets fans create original characters set in the Underground — complete with SOUL color, monster or human type, special ability, weapon, and a lore-consistent backstory. YouWare doesn't just generate one OC — it lets you build and publish your own OC maker as a shareable web app.
Your OC, Your Underground Story
Describe your character — their SOUL color, species, special ability, weapon, and key story beats. The AI generates a lore-consistent Undertale character profile ready for fanfiction, roleplay, or sharing with your fandom. No drawing skills required.

Key Features of the Undertale OC Maker
Every detail is grounded in the Undertale universe — from SOUL color and LV to monster type, special abilities, and Surface journey backstory.
SOUL Color & Type
Choose your OC's SOUL color — Determination red, Patience blue, Bravery orange, Integrity purple, Kindness green, Justice yellow, or Perseverance teal — and the AI shapes their personality, abilities, and arc to match.
Special Ability & Weapon
Define your OC's combat style — ice magic, fire spells, bone attacks, gravity manipulation — along with their signature weapon. The AI builds a complete ability set consistent with Undertale's battle system.
Backstory & Surface Memories
Generate a backstory that connects your OC to the Underground, their relationships with canon characters like Sans, Toriel, or Undyne, and their feelings about the Surface. Rich, lore-accurate, and emotionally resonant.
