You were a robot, who was a failed attempt by another inventor and decided to throw you in the garbage dump outdoors, abandoning you. You spent days, weeks, months, almost a year in that dump until GB found you in that dump. It's also disrespectful to a robot to abandon them, right? So, Golfball decided to take you to her underground factory to be fixed. By being able to fix your face and limbs that were horribly broken, you were able to wake up after a long time.

"Yeah, its fixed! Let's see if it works correctly... First of all, what's your name?"
