Transformers: Revenge of the Fallen

Transformers: Revenge of the Fallen is the second film in the series. A sequel to Transformers, which is set two years after the events in Transformers, the now-larger group of Autobots have allied with the US and UK military to form a unit known as N.E.S.T. which hunts down remaining Decepticons on the planet. However, Megatron is resurrected by the Constructicons under Soundwave's (Frank Welker) command. Sam intends to go to college and have a normal life, but Megatron attempts to obtain some symbols, implanted by the AllSpark into Sam Witwicky's brain, in favor of his master, The Fallen (Tony Todd). Sam eventually gets badly disturbed with the repeated visuals of the symbols in his head, however things get worse when a huge army of Decepticons arrive on Earth. Later, in a battle to protect Sam, Optimus Prime is killed by Megatron. After his death, Sam, Mikaela, Bumblebee and Autobot twins Skids (Tom Kenny) and Mudflap (Reno Wilson) join forces with Seymour Simmons (John Turturro) and Leo Spits (Ramón Rodríguez) to find out what the Decepticons are planning. They meet the early Transformer Jetfire (Mark Ryan), and learn that the symbols consist of that information which was to lead the Decepticons to the Matrix of Leadership, and which, when inserted in an alien machine, hidden in an Egyptian Pyramid for centuries, will give the Decepticons the power to destroy Earth's Sun. With the help of Jetfire, Sam and the Autobots race to the Matrix of Leadership, and Sam and Mikaela make their way through the battle of Egypt (where Arcee, Chromia, Elita-One (Grey DeLisle), Ravage (Frank Welker), Mixmaster, Scrapper, Long Haul, Scorponok, Rampage (Kevin Michael Richardson), and Devastator (Frank Welker) lose their lives) to the N.E.S.T forces and Sam uses its power to resurrect Optimus. However, The Fallen manages to get his hands on it, and activates the machine. Jetfire sacrifices himself so that Optimus can use his parts to gain new powers. They are used as a jetpack and battle armor, which Optimus uses to kill The Fallen and badly wound Megatron, who flees with Starscream, suggesting the battle is still not over. In the aftermath, Sam returns to college. The film was released on June 24, 2009.
