Nibelung Valesti is best known as the signature Purify Weird Soul attack of Lenneth, the lead valkyrie in Valkyrie Profile, the role playing game first released by tri-Ace and Enix in 1999. The name draws on the Nibelung legend from Germanic myth, matching the game's Norse setting and Lenneth's divine role. The shouted attack call became one of the series' most quoted lines, returning in sequels, remasters and crossover appearances, and gamers still share the short cry online to mark an over the top finishing move.
