Hello ,i have a question ,do Unicron spy or watch Optimus Prime all the time from time Optimus Prime got the Matrix until Optimus Prime death in 2005 movie. Do Optimus Prime actually know the Matrix was the only thing that can destroy Unicron? Do Optimus Prime and other Autobots and Decepticons have heard of Unicron before? Only Lithone and Junkion have heard of Unicron before 2005 ,am i right? Thanks.
