(Possible spoiler alert) Spin off / fanfic of the 2007 movie adaptation of transformers. Recap : An unknown amount of years ago, longer than imaginable, Megatron (leader of the Decepticons) destroyed the transformers home planet Cybertron. The Cybertronians are a race of bio-mechanical aliens : they're as sentient as humans, but their bodies and minds exhibit the outmost advance in technology. When Megatron destroyed his home planet he crash landed on earth and froze into a coma like state. A series of events happens where the AllSpark (a cube that creates the Cybertronian life) is taken, and Megatron is awakened. Amidst the fight between the Autobots and Decepticons , a number of mechanical objects gets blasted by the AllSpark bringing them to life. END OF RECAP.
Both the humans and transformers believed that the AllSpark was destroyed in Megatron's chest cavity, but unknown to them ....they were wrong. A small piece of the AllSpark broke off ,when it was being shoved into Megatrons life energy, so small it went unnoticed. As Megatrons lifeless carcass was lifted into the air to be dumped in the ocean , this small unnoticed piece fell.
