Don't let me go

Bumblebee is killed by Megatron and Optimus mourns over his death. Optimus' daughter is captured once she, Ultra Magnus, Hot Rod, Kup, Arcee, and Blurr land on Earth. Optimus has another daughter and is happy, but still grieves over his loss of Bumblebee. Rated T for violence and tragedy. OptimusxBumblebee
