A device of unknown origin and unimaginable power, the AllSpark can create life itself and was the source of the Transformer race. For millions of years, Autobots and Decepticons waged the Great War over controlling it, with the Autobots only managing to defeat the Decepticons after they sent the AllSpark through a space bridge portal, keeping it safely out of evil hands and effectively removing the wild card from remaining battles. If wielded by Decepticons, it would be a weapon of destruction like no other. In other words, same thing as the movie. It can also unfold really purdy.
