Fireshock is associated with Deltarune, the role playing game from Toby Fox that followed Undertale and was first released in chapters starting in 2018. Its short fire and electric hit has been clipped and shared by fans on soundboards and in fan edits, separate from a full battle scene. Because it is brief and clearly reads as a magical attack, creators reuse it outside the game for jokes, edits and reaction clips where something needs to land with elemental damage.
