What Is an Undertale Text Box?

In Undertale — the beloved RPG created by Toby Fox and released in 2015 — dialog is displayed in distinctive black text boxes with white borders and a pixel-style monospaced font. Each character's dialog is prefaced with an asterisk (*) and their name appears at the top in a unique color associated with their "soul" or personality. This iconic dialog style became instantly recognizable and is now one of the most frequently referenced visual elements in gaming fan culture.

The same style appears in DELTARUNE, Toby Fox's follow-up episodic game, extending the visual language to new characters like Kris, Susie, and Ralsei.

How to Create an Undertale Dialog Box

1. Enter a character name — this can be any canonical Undertale/Deltarune character or your own original character (OC).
2. Type the dialog text. You can start with an asterisk (*) for the classic Undertale narration style, or let the generator add it automatically.
3. Choose a color to represent the character. Classic character colors are pre-labeled — Frisk yellow, Sans white, Papyrus blue, and more.
4. Click "Generate Dialog Box" to render a styled preview.
5. Copy HTML to get the raw HTML code for use in websites, or Copy Text for the plain dialog text.

Character Color Reference

• Yellow (#FFD700) — Frisk, the protagonist

• Pink (#FFB6C1) — Alphys

Frequently Asked Questions

Does this work for Deltarune characters too?

Yes! Deltarune uses the same dialog box style as Undertale, so this generator works perfectly for Kris, Susie, Ralsei, Noelle, Berdly, and any other Deltarune character. Use Kris's red, Susie's purple, or Ralsei's green.

What font does Undertale use?

Undertale uses a custom pixel font called Determination Mono (based on Gaster's language) for the main text and a modified version of Comic Sans MS for Sans's dialog specifically. This generator uses Courier New as a close monospace approximation that works universally across all browsers without requiring custom font loading.

Can I use the copied HTML on my website?

Yes — the copied HTML is self-contained with all styles inlined, so you can paste it directly into any HTML page or site builder and it will render correctly.

Can I make dialog for characters not listed?

Absolutely! Just type any character name and choose whatever color suits them. You can create dialog boxes for any Undertale/Deltarune character, fan character, or completely original creation. For more character name ideas, try the Fantasy Name Generator.
