The Transformers cartoonEdit
Central City and its mayor started a celebration known as Autobot Day for Optimus Prime and his troops after they saved a solar power plant from the Decepticons. However, during the celebrations, the videos revealed a scandal, showing that the Decepticons were the "good guys" who were being exploited by Autobot propaganda. In addition, incriminating footage found by Shawn Berger showed Autobots stealing energy from an oil rig and talking of their plans to make the Earth theirs after the Decepticons were defeated.
Not surprisingly, the celebration was canceled as the people turned against the Autobots, and later turned into Decepticon Day. Thankless fleshies...
