In a universe where android aliens inhabit different planets, a race of androids called the Decepticons led by General Megatron planned to overthrow the caste system on their home planet Cybertron that they share with another race of androids called the Autobots. This goal might seem noble but Megatron's ways slowly change from noble to sinister as his hatred for the Autobot Orion Pax grows stronger after his ascension to Prime. All of this hatred towards this Autobot turns to hatred for all Autobots and a war is started that nearly tears Cybertron apart. Eventually Megatron's turn to darkness is complete after he makes a deal with the Lord of Chaos Unicron which causes the Decepticons to gain an advantage in the war. After seeing his former ally Megatron go beyond the point of return, Orion Pax now known as Optimus Prime leads a squadron of Autobots into battle and for a while it seems like they might win but Megatron starts bringing out thousands of Decepticons and overpowers Optimus causing Optimus and a couple other Autobots to have to leave Cybertron and later crash on the planet Earth.
