Gungnir is best known from Norse mythology as the spear of Odin, famed for never missing its target, and that legend is why the name is reused for overwhelming spear attacks in fantasy games and anime. As a short audio clip, it circulates among editors who want a ready-made finishing-move sound without recording one themselves. Its staying power comes from the name alone, which instantly tells a viewer that the attack is divine, unstoppable and final, even before the impact lands.
