THE HUMAN ELEMENT
After the last battle, Scourge realizes that a human component is necessary in order to activate the Fortress Maximus.

He amplifies the human part of his bio-energy a hundred times and gains control of Fortress Maximus. Scourge orders the giant robot to destroy the Autobots and the robot obeys! Dr. Onishi deduces that he needs more human energy to control the robot. Team Bullet Train immediately collects kids from around the world to harness their energy. The Autobots prove victorious, as they are able to use the kids' energy to stop the robot.

Using Karl, the Decepticons are able to order the robot to do their deeds. Koji and the Autobots appear and rescue Koji, defeating the Decepticons once again!

He sends mini Galvatrons around the world to gain control over kids with the plan to rule over future generations.
