Free. No limits.

Make your own Deltarune character in seconds: their look, their outfit, their weapon. Type it and see it.
An OC (original character) in Deltarune is your own character for the world of Toby Fox's RPG — a brand-new Darkner, Lightner, or Dark World hero who could stand right next to Kris, Susie, and Ralsei. GenTube turns your idea into art in about two seconds.
Four steps. One: describe your character — species, colors, outfit, and whether they live in the Light World or a Dark World. Two: pick their role — Darkner or Lightner, and what they do in the party, like healer, tank, or trickster. Three: set the style and background — quirky retro RPG, bold outlines, deep-purple Dark World palette. Four: hit create, then remix until the design feels right. Each generation takes about two seconds, so you can iterate fast.
Both. Describe canon faces like Kris, Susie, Ralsei, Lancer, Noelle, or Spamton, or invent a totally new monster, knight, or hometown kid. Mix and match to build a party that feels like it belongs in the Dark World.
Just ask for it. Say quirky retro RPG, Undertale style, bold black outlines, expressive cartoon, pixel-meets-storybook, and GenTube leans into that look. Add details like a spade head, glowing eyes, or a Dark World background to push it further.
It changes everything about the design. Darkners are born from Dark Fountains and wear their world on their sleeve — card suits, checkerboards, TVs, whatever object their world is made of. Lightners are the ordinary people of Hometown who fall into Dark Worlds and become heroes. A Darkner gets a wilder silhouette; a Lightner gets a normal kid look that transforms once the fountain opens.
Think like a Deltarune battle screen. Kris leads and acts, Susie hits hard, Ralsei heals and pacifies — so give your OC a job: tank, healer, spell-caster, or the one who talks enemies down. A clear party role shapes the pose, the weapon, and the outfit, and makes your OC feel like a real fourth party member instead of a background character.
Yes, and with Chapter 5 fresh out, the Dark Worlds are wide open. Make a card-suit Darkner, a TV-world host, a creepy puppet, or your own Knight pulling Dark Fountains. Give it a setting and GenTube builds the scene around it.
Yes. Make as many Deltarune OCs as you want, totally free, with no limits and no watermark. Try a hundred versions of your character until one feels exactly right.
Absolutely. Every creation can be shared and remixed. Drop your OC into the feed, let other fans riff on it, and remix theirs back. It is the fastest way to grow a whole cast of Darkners together.
