Autobot Day was the name of a celebration made by Humans in honour of the heroic Transformers the Autobots for all the good they did for the people of Earth.
Fiction
Generation 1 cartoon
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 videoes revealed a scandal stating that the Decepticons were the "good guys" who were being exploited by Autobot propaganda. In addition to this, incriminating footage found by Shawn Berger showed Autobots stealing energy from an oil rig and talking of their plans to make the Earth theres after the Decepticons were defeated.
Not surprisingly, the celebration was cancelled as the people turned against the Autobots. Thankless fleshies.... MMP1
