In the last episodes of Naruto manga, Sasuke had faced an incredible battle against one of the elders of the village of the leaf, a member of the group who ordered the destruction of the entire Uchiha clan, a person who had a leadership position when people ordered Hitachi to kill all people who loved, I’m talking about nothing more and nothing less than of Danz. I danz was supposed that it was part of the good, but from the beginning, manga has created a feeling of uncertainty among the readers, Danz always was guarded by the main characters, people never were to her around and he controlled part of secret forces in the village of the leaf in which imposed a jutsu that tied them to silence. It was always suspicious and we knew that Madara hated him, or at least had some sort of resentment towards him, but was not until these last episodes, where we realized their true intentions. It is that he had formed a group of very powerful ninjas loyal to him with special skills in protect and control the people surrounding those who have power, and with this began experimenting on himself and others, this supported research by Orochimaru. He always seemed a crippled man, but it turns out he was one of the most powerful ninjas of the leaf village, beneath all the bands that always brought with him had a lot of stolen the Uchiha clan sharingan eyes probably when the massacre was carried out by the hands of the own Hitachi years before the battle with Sasuke.And in his right shoulder was one of the experiments of Orochimaru, a face very similar to the of the first hokage, probably one of the experiments I do the evil ninja with some of the cells taken to test remove the ability to blend the water and earth elements and develop the ability to create plants or wood. I danz turned out to be a very powerful rival to combat, it was very close to kill sasuke with a special super genjutsu, the most powerful weapon available to a user of sharingan if you are willing to sacrificing your view forever.He was able to alternate reality and convert his own death in a dream as long as eyes remained abriertos.
