*Under editing* You all know of Ratchet as the cranky Medical Officer of the Autobots. What you didn't know was that he once had a sparkmate and a sparkling. Star his sparkmate was the sister of Megatron making his sparkling LunarStar the niece of Megatron. Megatron killed Ratchets sparkmate. As a result Ratchet and the Autobots sent LunarStar off into the cosmos in hopes of her surviving the war. She landed in earth 16 years ago and was adopted by the Witwicky family. She never thought that'd she would see her father again. Nor did Ratchet. I don't own Transformers T-T I wish I did.
