Kappa Tengu are a species of demons loyal only to the Tengu Shredder. They appeared exclusively in the 2003 TV series Lost Episodes season and the cell phone RPGs based on them: 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 character's name.

The kappa-tengu are credited as Wayne Grayson, Michael Sinterniklaas, Greg Abbey (Demons and Dragons) and Sean Schemmel (Legend of the 5 Dragons, Enter the Dragons, Part 1).
