Fan Casting Tranquil Fury in Sort by Tropes

This state of mind allows much whoop to be uncanned without undue stress. When the time comes for the showdown between The Hero and the Big Bad, do not expect to see an Unstoppable Rage. Instead, expect The Hero (or Anti-Hero)'s face to be serenely, eerily calm. They will not appear to be even slightly put off with the villain, but that won't stop them from trying to hack the villain to hundreds of tiny pieces. A defeat by someone in the grip of Tranquil Fury is likely to be more comprehensive than others, as the job will be done in a properly thorough fashion.
