Intro. There was a war of autobots and decepticons, but then a not very large meteor fell in the middle of the battle. All without exception turned into humans, they gave up the war momentarily without knowing what happened. Years later, the autobots teamed up with the military humans. One day, normal late afternoon, Optimus was returning from his afternoon walk, and heard a noise in the bush, and that's when Optimus saw a badly injured human-shaped decepticon. Optimus got a strange feeling of wanting to help him, and Optimus picked him up and took him to the base and took him to the infirmary. And then she took him to her house and left him in his room.
