Transformers

"Optimus Prime, Bumblebee, and their friends must unite every Cybertronian, Earthling, and ally they have to stand against this threat to all existence. But why is Unicron hell-bent on destroying Cybertron? What original sin did Optimus Prime's ancestors commit to earn this wrath? It's an all-out battle against extinction as the world-destroying, universe-shattering threat of Unicron comes to end everything."--
