"Megatron, for centuries now your evil has known no boundaries; from starting a war to extinguishing innocent sparks all in name of your sick twisted dream that so you aligned with The Fallen" Optimus said "And you my brother, think you can stop ME!" Megatron said "DON'T MAKE ME LAUGH!" Megatron said as he armed his weapon "Now we have arrived at the endgame, the final battle; the one where I shall finally get rid of you; soon I'll be the ruler of the Universe!" Megatron said as he broke out into a run "One shall stand" Optimus said "One shall fall!"
Optimus decided to strike first by throwing his fist in Megatron's mandible before slamming his fist into Megatron's chest and finally slamming his elbow into Megatron's knee making sending Megatron to the ground. Megatron retaliated with an uppercut before slamming his knuckles into Optimus' side before firing a shot from his cannon which barely missed charring his side and exposing his frame slightly. Optimus quickly activated his pulse rifle and pulled the trigger sending out a three round burst at his enemy who backed off and quickly took cover behind an offline transformer and used it as a shield "That's low even for you Megatron!" Optiumus shouted deploying his Energy Axe and tried striking Megatron down only to have be blocked by Megatron's mace
Megatron shove Optimus back causing him to skid backwards only to stop and few feet giving barely enough time to block Megatron's swing trying to get his processor, "Nice try Megatron" Optimus said kicking Megatron's legs out from under him sending him crashing to the ground as Optimus swung his axe down as Megatron rolled to the side and sent a shot out of his fusion cannon destroying Optimus Prime at point blank "I've done it, I have destroyed Optimus Prime!" he cheered
"Think again Megatron!" Optimus said picking up an EMP shotgun and fire at his brother; Megatron felt the EMP blast on his back causing the Decepticon leader to growled as he swung his mace around trying to destroy the Autobot leader who had ducked the swing and tried to counter with an uppercut but that was block by the open hand of Megatron "Nice try" the decepticon leader cackled as he throw the Autobot supreme commander against the nearest wall leaving a mass of cracks in it as the NEST officers jeered the Decepticon ruler. "All forces not involved in this battle retreat back to the cruiser and get into atmo" Lelouch ordered as he flew back to the Xantium. "Thank you Lelouch" Optimus said weakly "No worries" Lelouch said as the rest of the human NEST forces fell back to their ships. "This ends now Megatron!" Optimus growled activating his battle mask and swords.
"Oh good, you're ready to fight now are you" Megatron gloated "You and I both know how this will end Megatron, I may not beat you here but another place I have knowledge of will be your downfall" Optimus said as he rushed forward slashing Megatron with his sword on the side, "Give it up Prime you know I overpower you" Megatron laughed. "On this world you do, but on this other world the power you hold is useless" Optimus said as a space bridge opened up.
Optimus exited the gate on a mountain, the same one where five years ago he landed and fought against Megatron while meeting his future allies: Narita, it was the perfect place to finish something in the place it started, The war for Cybertron was won, but the threat of the Decepticons was still ongoing and now it was up to Optimus to stop it, the only way to do that was to offline Megatron and if he coul;dn't do that on Cybertron then he would do it on Earth.
Megatron blindsided Optimus forcing him several feet against jagged stone scrapping his armour "A Nice choice Prime, this served as the place of First Contact, Now it will be the place of The end, for one of us; which will be me" Megatron gloated as he stomped on Optimus' chassis before kicking him in the side forcing him to roll a couple of metres before pushing himself up before firing a shot at Megatron's knee which he slammed his elbow into before the Fallen's first demise, crippling him before the Autobot leader ran up and smashed his fists into the Decepticon's head sending the tyrant to the ground. Optimus slowly trudged over the weakening Decepticon leader; who push himself back onto his feet "Is that the best you have Prime?" Megatron asked as he fired a shot from his fusion cannon, only to miss due to Optimus side stepping it "you missed Megatron" Optimus said walking to his foe who was just on his feet when Optimus socked him back down "Maybe you should just stay down"
the autobot said before he grabbed Megatron before socking him back down making him create a crater in the rocky environment, damaging him heavily, causing him to seize up and tremble from the damage.
"I know I will hate myself for doing this but; stasis override, initialize emergency alt form generator" Megatron said as he was covered in red energy as he reformatted his body to help him obtain an edge over his Autobot rival. The familiar feeling of this form; that started it all five years ago.
Optimus Prime was now confused as his opponent had disappeared from his sight "Where are you Megatron?" Optimus asked not liking the fact he didn't have an optical view on Megatron anymore scared him. Suddenly his felt a sharp pain in his side, looking down five razor sharp blades were sunk into his right arm as a wave of super heated energy coursed through his arm blowing it up and then a shot of energon as fired from behind him near the base of spine making him fall down the rocky mountain side as Guren Megatron drifted down the mountain face taking pot shots at the injured Prime, most of them hitting him as he continued to fall down the hill finally stopping him he felt the flat ground "Now Prime. It's time for you to join your brothers in the well of the Allspark, deep within the matrix where all Autobots go when they are destroyed" Megatron said as the prime struggled to get up "I will never fall to you Megatron!" Optimus said as he now stood, energon flowing from his wound that Megatron inflicted him. "One shall stand and on this day; and I will make sure that it is not you!" Optimus said snapping his battle mask close and summoned his sword. "No Prime, it's you who shall fall on this day" Megatron said as he superheated the air around his claw before redirecting it to his fusion cannon "The final shot and then I shall be rid of the most annoying bug I have ever encountered, and it seems I'm at the advantage" Megatron said before the noise of engines were heard.
Over head was a NEST dropship that unloaded something heading straight for Optimus. It blasted Megatron "No one will stand in my way of destroying Optimus Prime and becoming Overlord of the universe!" Megatron howled in rage. "Well too late Megatron" Optimus said as his arm was reconnected before the drone "Wing Sabre Drone activate battle Protocol F" Optimus ordeded as the drone's under side extended out before fusing onto Optimus' back to form a jetpack as the two mini-guns folded down on the Prime's shoulder making them face Megatron who was changing back to his original Cybertronian form, the folded out piece came down forming a chest plate to protect his spark from the fusion canon from blasting him to oblivion. "So this is the dreaded Sonic Wing armour that I heard about that won you the Battle of Kalis in the early stages of the great war, only it is a bit different than I imagine" Megatron said as he armed his cannon first before he fired off a couple of shots, which Optimus dodged thanks to his Sonic Wing system that had helped him several times ever since the great war, only this time was the first time he used it on Earth since the Siege of Earth started "So, the antique system still works huh?" Jetfire asked over the comm.-link. "I thought I told you no contact unless necessary" Optimus said "That why I'm near just call And I'll transform into Jet Optimus" Jetfire said "Understood" Optimus said firing his guns at Megatron who returned fire with his cannon.
The two leaders were locked in mortal combat, wandering to offline the other will gunfire and missiles firing From Optimus Sonic Wing system and energy bursts from Megatron's fusion cannon. Optimus quickly took cover behind a rock pile as Megatron pounded him with cannon fire before returning fire from his wing mounted blasters at him when he could take the chance. "It is Useless Prime, for we both know who is going to win this fight" Megatron said firing a few round off at the Autobot';s hiding place before he walked around there to see Prime missing and no sign of him any where
Optimus disconnect the sonic wing drone and ordered it back to base before analysing the situation, both were heavily damage and nearly energon depleted but he knew that if he lost no one would be able to survive Megatron's reign and tyranny if he had been successful and conquered the planet. He knew what he had to do to keep the earth save from Megatron.
"Yes I concur Megatron so give up" Optimus said ripping the fusion cannon off Megatron's arm before activating his knuckle duster and punching Megatron in the head with it damaging the left side heavily before summoning his axe striking Megatron's chest and nearly severing his arm before he embedded the blade of his axe into the mandible, spinning around behind him and gripping the handle of the axe and pulled.
Megatron's head was disconnected from his body and was dumped on the floor next to his offline shell. Optimus stood victorious as the last sign of Megatron's spark faded into the void of deactivation. "Finally it's over" Optimus said walking away. Suddenly Starscream landed above the scrap of Megatron's corpse "Now that he is out of the way I can take over and ru" Starscream started to say before his head was destroyed by a blast from Optimus using Megatron's shotgun "Good riddance" he said dropping the weapon before resuming his trek back to the closet repair bay in the area
The Autobots and NEST were unloading the ships used in the Cybertron skirmish and the revival of The Fallen, Rodimus once off the ship raced out of the hangar heading for an isolated location so he could properly grieve for those he lost on Cybertron "Poor Rodeimus" Nunnally said as a medical crew took her off the med bay. Lelouch went into his old office and just sunk into his chair as Kallen came up to him and place a hand on his shoulder and a small smile to let him know everything was alright and now he could relax. "Its over" Kallen said saldy at the thought of those who they had lost since the start of the war of the Transformers.
Hours later, Optimus walked into heavily damage from his battle. Most there stopped what they were doing as Optimus heading from the Autobot med bay. As he took a step, the sound of clapping grew until finally it was a large roar of victory for the Prime who had vanquished his foe and brother with the bonus of shutting Starscream up permanently "OPTIMUS, OPTIMUS, OPTIMUS!" the troops chanted as he saw his transformer brethren who just nodded with a smile on their faces except for Ironhide. "Man, I wanted to scrap Starscream" he grumbled before getting struck by Chromia in the side. "I'm sorry my old friend" Optimus laughed befre being escorted by Ratchet into a healing chamber.
And from that day on, the transformers lived in peace; both Autobots and Decepticons enjoyed the peace that had been restored with Soundwave the new leader of the Decepticons and with Rodimus now a Prime ranked warrior, no one dared to end the peace and the new Cybertronian Golden Age that had come with it.
