Characters

After inadvertently discovering the lost relic known as the "AllSpark," Optimus Prime and his rag-tag team of Autobots are immediately attacked by the Decepticons. During their escape, the Autobots crash-lands near Crown City on Earth. 50 years later, Crown City and its sister city become a super-advanced metropolis, thanks to Prof. Isaac Sumdac's reverse engineering of Megatron's damaged body. Charged with rounding up the escaped Decepticon prisoners after the prison ship Alchemor crash-lands on the planet, the city becomes a battlefield as the Autobots emerge from their stasis and, with the help of the Teen Titans, Prof. Sumdac's daughter Sari, protect the population from the invading Decepticons.
