Combination Transformation

An advanced form of the Transformation Technique, the Combination Transformation transforms two users into one being. One user usually provides the chakra while the other performs the necessary hand seals. Naruto used this with Gamabunta in their fight against Gaara's full Shukaku form to assume the appearance of a giant fox (the Nine-Tailed Demon Fox in the anime). The Sound Four used this during the Chūnin Exam Arc to disguise themselves as the Fourth Kazekage's bodyguards (two in each). Kiba and Akamaru created their own variation of this technique with the Man Beast Combination Transformation: Double-Headed Wolf.
