Prologue

Before Echo became Mr. E, he was an obedient son to Dr. Julien. He was built with a purpose to protect those who cannot protect themselves. However, Echo's inability to feel pain led him to be clumsy. Years ago, Dr. Julien mysteriously disappeared. Without his inventor father around to keep up with Echo's maintenance, he was on the verge of breaking down for good. Echo must make a decision to naively wait, or turn on his ability to feel pain to carry on another day.
