Transform and Roll Out! Part2

Fifty earth years later, in the city of Detroit, a nanotech demonstration by inventor Isaac Sumdac results in a giant monster, which local police and SWAT are unable to combat. The Autobots are accidentally woken up from their stasis nap. Taking on new vehicle forms, the Autobots battle and defeat the nanotech creature, and also meet Isaac's daughter Sari Sumdac, a spunky 8-year-old girl whose security key card is transformed by the Allspark into a transformable key capable of healing the Autobots' injuries. Prowl is badly injured and healed by this method. The Autobots become the city's "Cybernetic Superheroes", and put their skills to work helping people.
