42. War Dawn

After the Aerialbots stop the Decepticons from killing half of Earth's leaders, Megatron comes to the conclusion that as long as the Aerialbots live, the Decepticons supremacy of the skies is in jeopardy. Megatron and the Decepticons go to Cybertron where Shockwave has built a device called the Chronosphere which is a time machine that Megatron plans to use to send the Aerialbots back to the beginning of time before Cybertron even existed. The Autobots learn of the Chronosphere and Omega Supreme takes the Autobots and Aerialbots to Cybertron to stop the Decepticons. Omega Supreme gets low on power and the Autobots go on their own to find the Decepticons. The Aerialbots are met up by Starscream and the Decepticon jets. The Decepticons tell the Aerialbots that they are not that bad and that they want to talk to them. All the Aerialbots but Silverbolt leave with the Decepticons. Starscream and the Decepticons take the Aerialbots to their base where they are being tricked to stand in front of the Chronosphere. Silverbolt arrives to warn them of the Decepticons' trick, but they are all trapped in the machine. The Autobots arrive to help and the Decepticons retreat. Optimus destroys the controls of the Chronosphere so the Aerialbots don't get lost forever. The Aerialbots wind up 9 million years in the past in the Golden Age of Cybertron before the war with the Decepticons began. Once there the Aerialbots meet up with a young robot named Orion Pax and his girlfriend, Aerial. The Aerialbots befriend the two and they see Megatron and his drone robots coming to the factory where Orion Pax and his workers keep their energon cubes. The Decepticons don't attack the Aerialbots because they don't know them yet because the Aerialbots are in the past. Megatron talks to Orion Pax about the energon cubes and Megatron orders his drones to attack the factory. Orion Pax and Aerial are devastated by the Decepticons and they retreat with the energon cubes. The Aerialbots take Orion Pax to get repaired and they find the home of a young Alpha Trion. The Aerialbots convince Alpha Trion to repair Orion Pax. Meanwhile, in the present, the Autobots are still trying to fix the Chronosphere so they can bring the Aerialbots back. The Decepticons find an old guardian robot with no head that is deactivated. Megatron tells Shockwave to reactivate it so he can use it against the Autobots. Back in the past, Alpha Trion introduces the Aerialbots to the new Orion Pax.....Optimus Prime. Optimus tells the Aerialbots that he admired Megatron just because he had power and he failed to see how he used that power. Optimus asks Alpha Trion if he can rebuild Aerial and Alpha Trion agrees to turn her into Eleeta 1. Megatron and his drones are battling the guardian robots when Optimus Prime introduces himself to Megatron and starts firing and his drones. The Aerialbots assist in destroying the drones before being brought back to the present by the Autobots. When they return, the Autobots are fighting the headless guardian robot that the Decepticons revived. The Aerialbots merged to form Superion and destroyed the robot. The Decepticons then retreat and the Aerialbots and Optimus Prime tell the story of how they rescued Optimus in the past.

43. Cosmic Rust

Megatron, Starscream, Astrotrain, and Rumble arrive on an Autobot-controlled planet called Antilla. Once there, they find that the planet is completely deserted. They come across a hologram of a dead Autobot who lived on the planet. He tells them to leave or they will rust and fall apart like the whole planet did. Megatron and Starscream are not scared like Astrotrain and Rumble and go into the capital city where they find a giant lightning bug statue that is a heat ray weapon. The Decepticons steal the device and leave the planet. Just as they depart, an asteroid follows them. Starscream and Rumble fire the heat ray on the asteroid to destroy it. A chunk gets blown off and flies into Astrotrain and hits Megatron in the shoulder, leaving a deep hole in it. The Decepticons arrive on Earth and Megatron has become very ill. Meanwhile, in New York City, a group of scientists from all over the world have presented the Autobot, Perceptor with an award for inventing a substance known as Chorostop which resists rust and corrosion. Perceptor tells the scientists that the Autobots plan to use the substance to coat the Statue of Liberty so that it can be preserved forever. Meanwhile, Megatron's condition has gotten worse and he tells Starscream to order the Stunticons and Blitzwing to capture Perceptor and bring him to him. While the Autobots are coating the Statue of Liberty with the Chorostop, the Stunticons and Blitzwing arrive and capture Perceptor. The Aerialbots go off to rescue Perceptor from the Decepticons. Blitzwing tells the Decepticons that the Aerialbots are following him and Ramjet and Dirge use the lightning bug heat ray on the Aerialbots. The Aerialbots retreat and the Decepticons take Perceptor to Megatron. Perceptor sees that Megatron has rust all over him from when the asteroid hit him. Perceptor then tells Megatron that Cosmic Rust wiped out entire races of robots like the Black Plague did to humans. Perceptor says that he will try to cure Megatron if he will surrender the heat ray. Perceptor shows Megatron a little bit of the Chorostop he has left and Megatron uses it on himself and the cosmic rust vanishes from his body. Megatron then radios the Autobots and tells them that he is releasing Perceptor just 3 miles from the Autobots' headquarters. Megatron says to pick him up before noon, because at noon a bomb will go off and destroy Perceptor who is infected with cosmic rust. Optimus Prime rescues Perceptor and take him back to headquarters before the bomb explodes. The Autobots examine Perceptor's body covered in the rust. The Autobots then become infected with the disease. Their only home is to get some Chorostop from the Statue of Liberty and mass-produce it using their matter duplicator. The Decepticons learn of this and go to stop the Autobots. The Autobots fight the Decepticons at the Statue of Liberty. The Stunticons merge into Menasor and begin using the heat ray, but it is destroyed by Superion. The Decepticons then retreat and the Autobots are cured of the cosmic rust.
