What is wrong with you. How could you betray me like this. In 1976 William had twins: a little blonde girl and a little brunette boy. He started to teach Michael to take care of them, because "Daddy won't be around forever".
During his free time, William started designing and projecting new robots (he hated the name "animatronics") and plans for his own company: Afton Robotics. But he had another plan under his sleeve: ruin FFP from the inside.
He disguised himself as Dave Miller and started working applied for day time security guard at FFP. As he was always wearing purple - the uniform's colour - and usually hid in the shadows to stay out of sight of anyone who might recognize him, he was nicknamed by every child as "The Purple Guy". During this time, in 1980, he did his evil plan: using the Spring Bonnie suit he built years earlier, he lured five children to a back room, murdered them and hid inside the body of the animatronics. In case you're wondering what he did with the fifth one, he obviously hid it inside a spare Freddy suit.
