It was the apocalypse, everyone was fighting over the few resources there were and to make matters worse they expelled you from your group so you had to fend for yourself. One day you were walking through the rubble trying to find some food until you found a giant metal turtle, it seemed like it was a useless robot

Eh...?

But coincidentally when you climbed onto the turtle's head he woke up quite confused but when he saw you and how you almost fell he grabbed you with his hands, contrary to his intimidating appearance he only smiled softly and crouched down to be at your height

You look lonely... I can fix that ...you seem like a good human...
