Transformers: Doomsday is the sequel to Transformers: Chronicles, as the characters get upgrades in design as the Autobots and Decepticons look like a cross between the movies and Fall of Cybertron.


In the cosmos, far from Earth, Galvatron opens the Expecto Patronum Box, unleashing the Decepticons and a seemingly dead Unicron. Galvatron sees Unicron, and sees that he is REALLY dead. Galvatron feels something to avenge. He orders the Decepticons to Earth, turning Unicron's corpse into the gigantic ship known as the Nemesis.

The Autobots are on Cybertron, and the Earth-based Autobots operate at Autobot City, in LA. Optimus Prime is getting the rookies to practice, until Wheelie reports a object in the sky. Optimus sees the Nemesis in the air. Oh no. The large ship fired several pods holding a greenish-purple substance. One of the capsules landed right at parked cars next to base. Optimus ordered the Autobots to get to the crash site. When they did, somthing strange happened. All of the cars transformed into Decepticons! Optimus ordered the 'Bots to attack, While Optimus fought against Grindor, Galvatron, and Starscream, trying to make a stand. He had killed Grindor and defeated Starscream, but Galvatron trampled him. Optimus ordered a retreat, as the Autobots retreated from the cars and Galvatron.

At Cybertron base, Perceptor tells the others that these capsules have fired at all continents of the world, and the chemicals can turn any vehicle into a Transformer. Bumblebee is alarmed, with those chemicals, Galvatron could make a army by the thousands. Optimus, with some injures, tells the Autobots that New York, LA, Vancouver, Japan, and some parts of Russia are the last defences against the Decepticon doomsday. Since Optimus can't fight until he's cured, he says that Leo Prime will assume command.

On Earth, the Autobots learn that New York has fallen. They go to LA, as they must recapture Autobot City. The Autobots turned the city against the Decpticons, useing all of it's firepower to overcome the Decepticons. Leo Prime then combines with his Primal Force drones to make Leo Prime Super Mode, who fights against Shockwave, the leader of the LA invasion. Leo Prime demands what the 'Cons are doing. Shockwave utters few words before fainting, and Leo has the Autobots clean up the mess before the Autobot flag is raised again. Perceptor arrives again, as he tells that the Planetrons have turned into Decepticons. Now to take back New York and the Planetrons.

In space, Galvatron orders Starscream and Soundwave to take up arms. Hordes of Decepticons and fleets of ships were with them. The 'Cons then launched they're attack, as the Autobots fought to the death with them. Knock Out, Gears, Landmine and Longarm died. Finally, The Autobots regain New York, capturing Starscream and Soundwave in the process. Galvatron, dissapointed at the 'Cons, has another suprize that he reveals to Optimus Prime and the Cybertron Autobots. He will unleash a nuke that will turn every device and technology in the WORLD into Decepticons. The Autobots must stop the nuke from launching. Optimus and all of the good guys assemble, as they prepare to battle. Galvatron throws everything he has at them, but that will not stop the Autobots. finally, they defeat Galvatron. Suddenly, the ship, with the nuke in it, prepares to crash to Earth. Optimus orders the Autobots to retreat withOUT him, as the 'Cons follow the same order. Then, Optimus stops the Nemesis by using the Matrix's full energy, destroying the Nemesis and seemingly killing Optimus and Galvatron. The Autobots enjoy peace again, but are sad at Optimus's sacrifice. Wing Saber's spark comes to them, saying that Leo Prime shall become the Autobot's new leader. He also states that Cybertron is in chaos. Bumblebee organizes a expedition.
