DELTARUNE Fight Simulator Game – Bosses, Filters & Controls

DELTARUNE Fight Simulator is a browser tool built by fans, and it is not the official game from Toby Fox. The DELTARUNE Fight Simulator footer credits both DELTARUNE and UNDERTALE to Toby Fox. This simulator centers on picking an encounter, scanning the available list and loading the battle you selected.

The encounter selector sorts entries under ALL, BOSS, chapter filters CH1 through CH5, UT, CUT and CUSTOM, and it adds a search field for particular fights. Encounters such as Jevil, Lancer, Clover and K.Round appear in the list, though the selection could change over time.

A Jevil encounter pairs Kris, Susie and Ralsei with FIGHT, ACT and item actions. Arrow keys move through the menus, Z or Enter confirms a choice, and X closes a panel. Ctrl+K opens the search box, while [ and ] switch between simulator tabs. Try to follow the on-screen choices of each battle rather than assuming every encounter carries the same actions.
