Terms of Use

Last updated 4 October 2026.

Deltarune Fight Simulator is an unofficial fan site. DELTARUNE is © Toby Fox. This site is not affiliated with Toby Fox. Do not present this site, its text, or its fan games as official.

The battles

The simulators are fan projects. They can leave out attacks, add attacks, and change controls. A battle can lag or play differently from DELTARUNE. Story notes on the boss pages spoil parts of the chapters. Those sections are labeled.

Credits and sharing

Each Scratch project is credited with the author and a link to the original. The credit on the battle pages is the CC BY-SA 2.0 note: name the author and link the project. Scratch changed its terms around 22 January 2026. A forum thread from February 2026 discusses that change. If you remix a project, keep the author's credit and follow the terms that apply to that project.

No warranty

The pages and the embedded battles are provided as they are. A battle can lag, stop, or differ from DELTARUNE.
