>>4400653(start of part 2) Robotnik became the highest-ranking official of the SSP and helped to create a space station known as the Death Egg to protect Earth from potential extraterrestrial threats. To aid in its mission of protecting Earth from potential extraterrestrial threats, the Death Egg is equipped with a weapon known as the Atomizer. The Atomizer is a fiercely destructive weapon that is a beam of pure energy which reduces any object it is fired at to its constituent atoms. However, the Atomizer can only be activated through the power of the seven Chaos Emeralds - magical gems that bestow godlike power. Robotnik becomes insane and broadcasts a message to the entire world that he is going to fire the Atomizer at Earth itself to effectively erase the entire planet out of existence.
Luckily for Earth, however, is that Robotnik only has six of the seven Chaos Emeralds. It's now up to Joshua 'Sonic The Hedgehog' Pinski to help save the world from the sinister Robotnik. But Josh is not alone in his quest to save Earth. Joining Josh are his three companions from high school - his best friend Miles 'Tails' Prower, his friendly rival the legendary boxer Theodore 'Knuckles' Hoffman (Vin Diesel) and his on-again-off-again fortune teller girlfriend Amy Rose (Sandra Bullock). Using Miles's latest invention, a device known as the Chaos Emerald Detector, they must find the last Chaos Emerald before Robotnik does in a desperate race against the clock. (end of part 2)
