A/N I was in a hurry to finish this story because of school so I did not make a scene where the autobots actually go to earth but they are on earth
There they were Optimus Prime and Megatron they had finally defeated sentinel prime but something went wrong Megatron had suddenly had an urge for power and he shot Optimus in the back extinguishing his spark. Megatron had then revealed that he had dark energon and summoned The Fallen. Bumblebee was on his way when he had saw Optimus hurt so he had to help him "Optimus what happened to you" Bumblebee asked Optimus with his last breath said "Megatron betrayed me." Then a few moments later decepticons had appeared and started attacking them Bumblebee had to carry Optimus's body and ran to a nearby cave to survive the attack. After the attack Bumblebee had to call for backup but first he needed to get Optimus fixed up so he set off to go find some parts to fix Optimus's wounds. They found some parts at a scrapyard so they took them and covered up his wounds. "How does that feel, Optimus?" said Bumblebee. "Feels a little heavy but itl work for now" said Optimus. They then found some parts to make a radio to call for backup they then had transformed and drove to see a giant tower and they had seen deception's there so they had went there to stop whatever the decepticon's were up to. They had finally made it to the Decepticon Tower where they had climbed up the tower and spotted by The Fallen. They had a fierce battle with The Fallen The Fallen had stabbed Bumblebee in the back killing Bumblebee and then he kicked Bumblebee's life less body off the tower. The Fallen then gave Optimus a swift blow to the head knocking him off the tower and him out landing on the ground. He woke up confused for a second then remembered what happened he thought to himself "i need to revive Bumblebee" he then transformed and drove to the scrapyard to try and find the communication device so he can get other autobot to help him. more autobots came to help. Optimus set up a plan to revive plan was to trick The Fallen that we had give up and that he had won and that we wanted to join the decepticons and he fell for it and let us roam freely in the tower and then we went to the infirmary to get Bumblebee's body and then to the core of the tower and blow up the core. And revived Bumblebee. So they transformed and made their way back to the Decepticon Tower to activate the plan and the plan had worked they had revived Bumblebee.
