Byakko (白虎, White Tiger) is a Japanese spear (槍, Yari) from the 2003 TMNT animated series. It is introduced during the Lost Episodes as "the hungry ghost who calls the cleaving wind". Per its description, it has the ability to whip out crescents of razor-sharp wind. Donatello, its owner, was so proficient with this weapon that he was able to suck in an entire lake just by generating a mini-tornado. Byakko is one of the Fangs of the Dragon, and was the weapon claimed by Donatello from the Spirit Forge. It is unknown what happened to Byakko after the Shredder's defeat.
Juto(describing the weapon): Byakko, the hungry ghost who calls the cleaving wind.
Don: I'm a mean, green beatdown machine!
Byakko is a Karigata Yari, a yari with two side blades pointing down.
