The Nezumi-Tengu are a group of minions of the Tengu Shredder's army. They appeared exclusively in the 2003 TV series Lost Episodes and the cell phone RPGs based on them, Teenage Mutant Ninja Turtles: Ninja Tribunal and Teenage Mutant Ninja Turtles: The Shredder Reborn. The Nezumi-Tengu are a breed of ratlike demons, transformed from regular rats. The term Tengu was used as a generic term for Japanese demons in The Lost Episodes, and thus, was affixed to the characters' name.
