OPTale (Overpoweredtale) Is an AU where not only have the characters been altered, but the timeline is forever stuck in the hardmode setting. After the human named themselves "frisk" in the menu, the game couldn't quite handle it, and sent the human into a completely new timeline. The game hadn't quite adapted to the name "frisk" being used by users, so it instead it renamed the fallen human entirely. Fritz, the newly named human, journeys through the underground to find all the characters have turned somewhat human, and all have different names. However, since the game is set to hardmode permenantly, every character has become considerably more overpowered, hence the name OPTale.
