Transformers - The Ark

The Ark crashed into a volcano and the Autobots and the Decepticons were terminated. The crashed ship and its dead occupants lay there lifeless for 4 million years. And then, suddenly, the volcano erupted which reactivated the Ark. From the Ark, a sensor drone was launched to gather data to send back to the ship. It went around scanning things such as jets and cars and radios and then returned with all this information. With this information, it started a revival program to rebuild all of the previously dead occupants.
