Mythra first appeared as a Blade in Xenoblade Chronicles 2, the Nintendo Switch role-playing game released in 2017, before joining Super Smash Bros Ultimate as a playable fighter alongside Pyra in 2021. In Smash, each fighter has distinct defeat and knockout audio, and short clips like this one are ripped from gameplay and shared on soundboards for editing. They remain popular because Smash montages, reaction videos and meme edits need instant, recognisable audio cues, and a character-specific knockout sound carries more personality than a generic impact effect.
