<P> Hidden on Earth as common, everyday vehicles, the Autobots are forced to emerge when Megatron and his Predacons arrive and wreak havoc in their attempts to attain the power of Earth's various energy sources . </P> <P> In this universe, Optimus Prime transforms into a fire engine . The front section of the vehicle detaches and becomes Prime himself, armed with "Blaze Blaster" cannons . To attack, he is able to use his headlights, known as the "Fire Flash" attack, and leg wheels, known as the "Gyro - Strike". The rest of the vehicle transforms into a mobile battle station / refueling port / communications array and can combine with Prime as additional weapons and armor, forming his super mode referred to as "Super Fire Convoy". The ladder / hose section houses Prime's Power Stream water cannon, capable of shooting freezing streams of water, called his Blizzard Storm attack . It also contains a quartet of rocket launchers . In super mode, his feet contain missile launchers than can mount to the shoulders of his regular robot mode . In this mode, he can fire his fists for his "Flying Fist" attack . </P> <P> Optimus Prime and his brother, Ultra Magnus, were created at the same time by Alpha Trion, but when Prime was chosen to carry the Matrix, Magnus felt ignored, and was left carrying a grudge against his brother . </P> <P> Later, Optimus pursued Megatron to Earth to stop him from pillaging the planet's energy resources . Prime's loyal team of Autobots clashed with Megatron's Predacons on many occasions, stopping their schemes with the aid of Koji, a human whose father had been abducted by the Predacons . Prime and Koji went on to form a strong friendship, although Prime blamed himself for Koji's father's abduction . Optimus proved his bravery on many occasions, battling and defeating Sky - Byte in an underwater duel and personally rescuing Side Burn from a Predacon trap . Later, when Megatron targeted a tanker truck to scan as the alternate mode of the final protoform, Optimus Prime leapt into action in order to save the truck's human driver and, as a result, the tanker, Prime and the human were all scanned . With an infusion of Megatron's spark energy to complete the concoction, Scourge was born, emerging from his pod as a dark twin of Optimus Prime . Prime's pleas to make Scourge remember his original Autobot loyalties fell on deaf ears . </P>

No sacrifice is too great in the service of freedom
