Based off of Wall-e, this is about one of the early models of cyborgs that mankind made. He is model 837 and has been the only living organism on Earth for centuries and evolved from being a task driven machine to a free thinking and gentle cyborg. A female and more advanced cyborg arrives on the planet and takes him back with her into space where the now evolved humans were living in a ship. With centuries of diversity between 837 and the current race, things may be messy.
