Abandoned Human Robot (Cyborg X RWBY)

20 Years ago, before Ruby joined Beacon or Penny was created. Atlas needed someone who was wanting to see if they could put a humans heart, brain, and soul into a robot. A young boy offered himself to be the test subject. The test was a success, but a couple of years later something went wrong and the robot went missing.

But, 20 years later, Jaune and Pyrrha found a Death Stalker in the cave, where apparently the human robot was hidden a capsule behind the Death Stalker. When the Death Stalker started screeching and busted through the entrance of the cave, it vibrated the inside of the cave and the capsule was in was knocked over and busted the door open. With the door open, it woke up the robot from his slumber and now he walks once again upon the land. But, he can't remember anything about his past before he became a robot or how he got here.
