Kappa Tengu

Kappa-Tengu are a group of minions of the Tengu Shredder's army. They appeared exclusively in The Lost Episodes and the cell phone RPGs based off of it Teenage Mutant Ninja Turtles: Ninja Tribunal and Teenage Mutant Ninja Turtles: The Shredder Reborn.

The Kappa-Tengu are simply a stylized version of the Japanese demon known as the Kappa. The term Tengu was used as a generic term for Japanese demons in The Lost Episodes, and thus, was affixed to the characters' name.
