When he found out that the Autobots were on Earth, he took control of one of Sumdac's prototype pocket bots and sent it to their hideout - an abandoned automotive plant. Upon reactivation, he immediately found out that it was Starscream who betrayed him, and immediately plotted payback, but needed a body to do so. The surge of the key's power reached Megatron's head, putting him back online. His head was not reactivated until "Home is Where the Spark Is", when Sari used her Allspark Key to open her father's door to his lab. Megatron's head subsequently became a keystone for Sumdac's various robotic creations, which he used to help convert Detroit into a technological metropolis within the next 50 years. Due to the explosion that crippled the Autobots' craft, Megatron's lifeless body crashed on Earth, contracting "space barnacles," while his disembodied head was found in rural Michigan by a young Isaac Sumdac. Even though he found it, Megatron was betrayed at the beginning of the series by Starscream, who planted an explosive device on his back. As revealed in "Transform and Roll Out", Megatron had spent 4 million stellar cycles (years) in search of the Allspark.
