Sword of Tengu

The Sword of Tengu is an energy weapon created by the Utrom Shredder Ch'rell.

History
As the new Shredder, Ch'rell had a number of sword smiths to craft the blade out of Utrom metal. Once it was completed, he attached it to a handle, electrifying it. He quickly came up with a tale of its creation, how it "fell from the Heavens and was crafted by Goblins", and killed the creators.

Using the sword, the Shredder conquered Japan, brought the Tokugawa clan to power. But due to some unexplained reason, he lost the sword which eventually ended up in a museum in New York. Ch'rell sent his Foot ninja to retrieve the sword, which he had two tech use as a component of a sonic cannon to excavate an Utrom exo-suit from Hudson river. But the Turtles managed to retrieve the sword.

Later, when the Shredder assumed they were dead, the Turtles strove to take down the Shredder and brought the Sword of Tengu with them. It proved valuable when they faced the Foot Mystics, as Splinter, without the glove, defeats them. But at the top, Ch'rell reclaimed the sword but lost it again to Leonardo. In a slashoff, Leo cut off the Shredder's head, not knowing of his Utrom nature. Coupled with Baxter Stockman's cybernetic arm, the sword's energy rendered the tower useless, in which a feedback loop destroyed the sword.

Capabilities
Using Utrom technology, the sword is exceptionally powerful. It can fire sonic waves when swung and shocks anyone who tries to grasp it without a protective glove, except a true ninjitsu master, who can hold with for a short time before his hands burn, and the Shredder himself, because his exo-suit protects him.
