Kishimoto has already stated that he grew up a big fan of Akira Toriyama and of DBZ. Yeah you notice the influence in the Orange and BLue suits in te main character and the being present primarly in his rival. SPOILER!............................................................................................................................................................................................................................................................. The pervert masters that help the main character grow and the strong tempered women. In the bad guys the female like antagonist in Orochimaru/Frezeer. Theirs more but I think thats about it.
