Rockman X (ロックマンエックス)
Background
However, these robots were defective, and started breaking the Laws of Robotics. This kind of "evil" Reploids were labeled Irregulars (or Mavericks), and soon a group of Irregular Hunters was gathered to mantain peace.
X joined the Irregular Hunters by himself, since he felt responsible for letting Dr. Cain create the defective Reploids.
