There already a major rewriting of TF history in TFP. Back in G1, Optimus Prime died and passed on the Matrix of Leadership. Which led to a young Hot Rod reformatted into Rodimus Prime, whUo in turn unleashed the power of the Matrix inside Unicron and destoryed him. As we've seen, in TFP season 1 finale, Optimus Prime lives and unleashed the Matrix directly to Unicron's spark(or anti-spark). In a way this as a huge historical alteration. Most likely a way for the show writers to fullfill many TF fans' wish that Optimus Prime had never died in G1 and remained the leader of the Autobots. What other TF histories would you like them to change in TFP?
