Naruto has many interesting characters – including Gaara of the Desert. He started off as a villain who enjoyed killing, but he went on to become one of Naruto's closest allies. Naruto's story takes place over a four-to-five-year span, and Gaara managed to achieve a number of things during that short timeframe.
