Kisame and Zabuza were part of the world of Naruto, Kisame belonging to Akatsuki and Zabuza part of the Seven Ninja Swordsmen of the mist. They both have their past where they battled and did what they had to do. They have now both passed on, that’s why I post this as these were some of the better characters which never disappointed, even in their young shinobi forms they look awesome.
