Kyuubi's Eye

At the age of six, Naruto was attacked by a group of villagers. They left him hurt and bleeding on the street, a new brand on his shoulder. When a woman was about to leave, Naruto began to change. His eyes became the same of a fox's, and his power red. With his newfound power, Naruto took revenge on the woman. When he was done, he returned to normal. But his left eye never changed.
