Inazuma (稲妻, lightning) is a mystical three-section staff (三節棍, sansetsukon) from the 2003 TMNT animated series. It is introduced during the Lost Episodes as a weapon with the ability to "command lightning from the heavens." It is able to extend beyond its normal reach and lash out at very high speeds like a whip, living up to its "lightning" moniker. Inazuma is one of the Fangs of the Dragon, and was the weapon claimed by Michelangelo from the Spirit Forge. It is unknown what happened to Inazuma after the Shredder's defeat.
Juto(describing the weapon): Inazuma, which commands lightning from the heavens.
Mikey(warding off kappa tengu): Come on, Inazuma!
Mikey(after warding off kappa tengu): I'm never giving these back!
