A Cybertronian escape pod travels from Cybertron's solar system to Earth's and crash lands to the Philippine Sea and travels straight to Tokyo, Japan. The Cybertronian revealing himself as Shockwave emerges from the sea and slowly walks straight to the city.

"Berserker this is Shockwave!"

"Berserker here!" Berserker replied.

"I have arrived to Earth. Inform Megatron immediately!" Shockwave ordered Berserker.

"You're late Shockwave, we arrived in Tokyo already!" Megatron eavesdropped on the conversation replying to Shockwave through Berserker's comm-link.

"That possibility is—logical!" Shockwave said ending the transmission as he watched the buildings being blown up and the natives running in fear. Shockwave then turned around and saw Menasor rise out of the water and walked towards the city.

"Remarkable!" Shockwave said amazed by the sight of a Combiner.

"Welcome to the Combiner Wars, Shockwave!" Megatron said to Shockwave through the transmission.

Jordan:

"Ugh—I'm getting sick and tired of hiding!" Crosshairs said continuing to complain again.

"What do you want us to do Crosshairs? What do you want us to do? The Decepticons have the upper hand with the Enigma of Combination and two of our Dinobots are missing!" Hot Rod said to Crosshairs getting annoyed by the older Autobot's constant whining.

"The two Dinobots aren't missing!" The weak Optimus Prime said.

"Wait what?" Hot Rod replied.

"I sent Grimlock and Slug to follow Megatron and to inform us where they are currently at!" Optimus explained.

"Optimus, the Dinobots are huge what makes you think they won't be spotted?" Ratchet asked.

"We Dinobots have been on this planet for eons and have learned to adapt to it, as for stealth we make tunnels underground like Earth's moles!" Scorn explained.

"I see!" Hot Rod replied.

"(Wheeljack groans) you okay Wheeljack?" Ratchet asked noticing Wheeljack groaning in pain.

"Yeah I'm fine I just took on hell of a beating from Onslaught and Stinger!" Wheeljack said lying down on the ground with his left hand on his chest while Ratchet was leaning down to check on him.

"Wait—what's this?" Wheeljack noticed a bump on his chest.

"Open up your chest plate!" Ratchet said, Wheeljack then opened his chest plate and Brains flies out of his chest and lands on his hands.

"Oh Primus I forgot!" Wheeljack yelled.

"Wheeljack what's wrong?" Dino asked.

"It's Brains, dammit I forgot about him!" Wheeljack yelled while holding Brains who was currently in stasis and was still missing his right leg.

"Where did you find him?" Bumblebee asked.

"I rescued him in Kaon after Soundwave's mini-cons took out our power and the other Decepticons attacked, I rescued him and hid him near my spark chamber and managed to forget about him!" Wheeljack said.

"Can u help him?" Wheeljack asked.

"Yeah I can but it's going to take a while! First off his leg is missing, second of all he is in stasis from lack of energon so he requires a transfusion—"

"I'll give him a transfusion!" Wheeljack interrupted Ratchet.

"Okay and third of all it looks like some beating you received affected him also, I mean look at him—his neck is completely broken, I mean he's lucky to still be alive and have his head intact but PRIMUS IS THAT ONE SERIOUS NECK INJURY!" Ratchet yelled starting to freak out over the amount of repairs he has to do to a mini-con.

"We can worry about Brains later, right now we need to find those Combiners!" Optimus explained.

"Agreed boss!" Hound said standing right beside Optimus as he tried to get up.

"You agree with everything he says!" Crosshairs annoyingly said.

"Shut up Crosshairs!" Hound immediately talked back to Crosshairs. Grimlock and Slug successfully managed to track down the Decepticons and found themselves in Tokyo, Japan via. Travelling underwater.

"Uh great—I'm soaking wet!" Slug said complaining as he and Grimlock emerged out of the water.

"Relax Slug it's just water!" Grimlock said to Slug.

"JUST WATER?" Slug yelled while shaking off the water dripping on his chassis.

"Slug shut up!" Grimlock whispered.

"THIS…WATER IS GOING TO RUST MY EVERYTHING!" Slug continued yelling.

"Slug shut up! The Decepticons are here!" Grimlock whispered trying to make Slug quiet down.

"Holy scrap we found them!" Slug said watching Menasor and Devastator destroying multiple buildings.

"Let's get them!" Slug said ready to charge at the Combiners.

"NO!" Grimlock moves his left hand to block Slug and make him stop in his tracks.

"What is it now Grimlock?" Slug asked.

"We came here to report to Optimus where Megatron and his Combiners are currently at!" Grimlock explained.

"Well then let's report and then kick some tailpipe!" Slug said.

"We can't not without backup, there is only two of us and thousands of them!" Grimlock explained.

"Are you serious? We are towering behemoths and you're worried about some tiny little Decepticons soldiers?" Slug began questioning Grimlock's bravery and thinking.

"We are the same size as the Combiners, if we fight both the soldiers and the Combiners at the same time we will easily be overpowered and defeated!" Grimlock explained.

"I'm starting to see your point!" Slug said.

"We need to find a place to hide and then we can call Optimus!" Grimlock said as he and Slug tried sneaking away from the Decepticons hoping none of them will spot the two Dinobots, they didn't even want the two Combiners to notice them.

"Grimlock to Optimus I repeat, Grimlock to Optimus we have Megatron and his Combiners. They are currently in Tokyo, I repeat they are currently in Tokyo!" Grimlock contacted the Autobots to inform them of the Combiners' locations.

"Great work Grimlock we will reuniting with you there as soon as possible!" Optimus replied to Grimlock.

"Better hurry, we are the same size as the Combiners so we are likely to be easily caught!" Grimlock explained to Optimus.

"Understood Prime out!" Optimus said ending the transmission.

"So Megatron is in Japan?" Sideswipe asked.

"Quite cliché if u ask me, Japan has made multiple stories about giant monstrous creatures terrorizing their country!" Wheeljack said.

"It's more convenient if you think about it!" Drift said.

"Enough talk, my brothers are outnumbered two to thousands, we need to get to Japan immediately!" Scorn said concerned for Grimlock and Slug.

"Very well then let's go!" Dino said walking away from the others and transforming into his vehicle mode with Crosshairs and Drift doing the same.

"Strafe. You have anything to say?" Bumblebee asked but Strafe just stood still behind Scorn.

"Does he ever talk?" Bumblebee asked Scorn.

"He is…the strong silent type!" Scorn said explaining Strafe's personality.

"Does he make any sound?" Sideswipe said walking away from Bumblebee and the Dinobots.

"If you count him squawking while in Dino form?" Scorn said mocking Strafe. Strafe then replies by punching Scorn on the shoulder.

"AUTOBOTS ROLL OUT!" Optimus shouted as all the Autobots transformed and drove heading straight from Jordan to Tokyo while Strafe flew up in the air in his two-headed Pteranodon form and Scorn in his Spinosaurus form tunneled underground. Back in Tokyo, Megatron and his Decepticons watched the Combiners destroy the entire city.

"This is a proud day for us Decepticons, the seven Primes were fools to believe that their descendants wouldn't find the Enigma and start the Combiner wars!" Megatron said boasting over his accomplishment.

"Ah I just love the smell of smoke and debris caused by us!" Starscream said inhaling the smoke coming out from the fire and the debris.

"This is great Shockwave, we are finally winning!" Nitro said to Shockwave

"Your excitement is—logical!" Shockwave replied.

"Ah man!" Mohawk said sitting down next to Hooligan and getting upset.

"What's wrong Mohawk?" Hooligan asked noticing that Mohawk is sad.

"It's just when we landed on Earth, Nitro wasn't around Shockwave as much and both he and I unexpectedly began turning into close friends and now…"

"Nitro is back to being a fanbot!" Hooligan said staring at Nitro worshipping Shockwave.

"From what I've seen, Nitro a literal badass but now he's down on his knees worshipping Shockwave like he's Primus!" Mohawk said getting upset how Nitro seemed to have forgotten about his best friend and is now back to praising the emotionless Decepticon scientist, Hooligan didn't know what to say and just simply looked down at Mohawk.

"Lord Megatron!" A Decepticon soldier.

"What is it?" Megatron aggressively asked.

"I've picked up two Energon signals….and they are not Decepticons!" The soldier said.

"Somebody go investigate!" Megatron said.

"Hey Nitro, let's go check it out!" Mohawk said with an exciting tone in his voice.

"I don't know, Shockwave might need my help and…."

"Nitro—Go with him!" Shockwave interrupting Nitro.

"Yes Shockwave!" Nitro said transforming into his Jet form and flies off after Mohawk jumps and hitches a ride on him. Nitro transforms into robot mode and lands with Mohawk near the energon signal and they begin walking around the damaged buildings trying to find the source of the energon signal.

"Alright, the sooner we find the cause behind that signal, the sooner I can return to Shockwave!" Nitro said slamming his fists together looking around while Mohawk sighed from sadness.

"What's wrong Mohawk?" Nitro asked.

"Nothing it's just grrr—When you were away from Shockwave, you were shown to be a powerful and capable fighter and we both had each other's backs from then on and now you're back to serving Shockwave!" Mohawk yelled out.

"Awkward!" Slug said eavesdropping on Mohawk's and Nitro's conversation.

"QUEIT!" Grimlock loudly whispered to Slug trying to shut him up.

"So what you're telling me is that your fragging jealous?" Nitro asked getting mad over Mohawk's complaints.

"Hell yeah I am fool, you had my back for the past months and I had yours and now we can't go anywhere anymore, you are going to be stuck working in the laboratory again!" Mohawk started yelling.

"Mohawk are you out of your mind? I'm still going to be scrapping Autobots with you I'll just at times need to help Shockwave at the lab and if you want you can help us, I bet you can even torture some prisoners!" Nitro said trying to calm his little friend down.

"Did….did you just say torture?" Mohawk asked getting excited.

"Of course, I don't think anybody else knows how to melt Autobots!" Nitro said getting Mohawk even more excited.

"Melt! Melt! MELT, MELT, MELT, MELTY, MELT, MELT!" Mohawk said jumping around screaming melt in a psychotic way even creeping the gigantic Dinobots hiding behind them both.

"Okay this guy is messed up!" Slug said.

"Agreed!" Grimlock replied.

"You want to scrap them?" Slug asked, Grimlock looked at Slug but didn't reply, the two Dinobots simply transformed into their Dino forms and attacked Nitro and Mohawk.

"Holy crap, RUN!" Mohawk yelled as he grabbed hold of Nitro who quickly activated his jet boosters and flew into the air to avoided getting eaten by Grimlock.

"Megatron this is Nitro, I have found the source of the Energon signal. They are Dinobots, I repeat Dinobots!" Nitro contacted Megatron.

"Dinobots? How many?" Megatron asked.

"Just two, one of them is their leader!" Nitro replied.

"Scrap—COMBINERS ATTACK!" Megatron yelled ordering Devastator and Menasor to attack Grimlock and Slug. Menasor and Devastator charged towards Grimlock and Slug and grabbed the Dinobots by their necks trying to pin them down. Devastator could only stand on all fours and used it to his advantage by crushing Slug's head against the ground while Menasor trapped Grimlock between his forearms via. A chokehold trying to make the Dinobot leader submit. Optimus and his Autobots arrive in time and watch Menasor and Devastator dragging both Grimlock and Slug to Megatron.

"No. They have already been captured!" Optimus said with a worried tone in his voice.

"We still have time to save them Optimus, let's go!" Dino said getting out of the water and pulling Sideswipe up into the surface as Optimus and the others started coming out of the water. Menasor and Devastator brought Grimlock and Slug to Megatron and the two forced them to kneel before Megatron.

"How humiliating, the almighty Dinobots have been brought down by my Combiners, I can never understand why my Decepticons feared you!" Megatron said mocking the exhausted Dinobots.

"I can still feel the teeth!" Hooligan said shivering in front of Barricade and Onslaught.

"Such remarkable specimens, I could build super-soldiers for you made out of their very metal!" Shockwave said fascinated by the sight of these Dinobots.

"Shockwave my old friend, why have a super-soldier when I already have these Combiners?" Megatron said questioning Shockwave's logic.

"With the Enigma of Combination in my hand, I am unstoppable!" Megatron said lifting the Enigma of Combination with his left hand but that soon proved to be his undoing, suddenly a Plasma bullet hit Megatron's hand causing the Enigma to fly out of it and land on the ground.

"WHAT?" Megatron said looking to the direction from which the bullet originated.

"Your Combiner Wars will be short-lived Megatron!" Bumblebee said aiming his Plasma Cannon at Megatron with Optimus, Hot Rod, Sideswipe and the rest of the Autobots standing behind the yellow scout.

"NO! DECEPTICONS ATTACK!" Megatron yelled ordering his troops to attack while retracting his fusion cannon and firing back at the Autobots.

"Grimlock get the Enigma I'll handle Megatron!" Optimus said charging towards Megatron with his sword and shield at hand, Optimus pounces and knocks Megatron off his feet sliding down to the ground against the pile of rubble.

"You are starting to get on my nerves brother!" Megatron said quickly recovering from the fall and getting back up.

"If I remember correctly Megatron—you said that we were brothers…Once!" Optimus said getting up and aiming his sword at Megatron.

"Let's just finish this!" Megatron said slowly moving the tip of the sword away from his face with his right hand.

"One shall stand, one shall…"

"Oh for god sakes!" Megatron sighed annoyed by the same speeches Optimus continues to deliver during each battle, he hits Optimus Prime's head with his axe and the two began fighting aggressively swinging their blades towards each other and firing back with their fusion cannon and shield.

"SLUG! WE NEED TO GET THE ENIGMA!" Grimlock roared running towards the Enigma lying on the ground just three feet away from them.

"I'M COMING GRIM!" Slug yelled only to be pounced by Devastator, Menasor charges after Grimlock and pounces at him. Grimlock falls to the ground and begins sliding, scratching most of his face due to the damaged debris, he stops sliding but his jaw gets really close to the Enigma allowing him to grab it with his jaws and hide it in his mouth.

"Stay down Dinobot!" Devastator growled trying to keep Slug pinned down to the ground but Devastator gets too close to one of Slug's horns and accidentally gets impaled in the throat, Devastator lets go of Slug and grabs hold of his throat roaring in pain whilst collapsing to the ground and crushing several Decepticons. Slug charges towards Menasor knocking the Combiner off his feet and making him fall to the ground and nearly crush both Optimus and Megatron during their battle. Slug walks towards the exhausted Grimlock who opens his mouth and drops the Enigma to the ground, the Enigma then shines a light on both Dinobots causing them to combine by accident.

"WHAT THE SCRAP IS THAT?" Onslaught yelled while fighting Drift and Crosshairs. The Autobots then turned around to look and so did the others Autobots and Decepticons. What they saw both startled and amazed them. Grimlock and Slug had combined into the largest Combiner in Cybertronian history, the Combiner still resembled Grimlock's Tyrannosaurus Rex form but with Slug's stegosaurus-like spikes, jagged shoulders and Slug's Triceratops horns on both the upper and lower jaw.

"By the Allspark!" Shockwave said stunned by the sight the gigantic Dinobot. Suddenly out of nowhere both Devastator and Menasor pounced on the Dinobot Combiner.

"NO!" Optimus yelled buying Megatron enough time to shoot him in the chest.

"Your only Combiner won't be enough against two of mine, it's over Prime!" Megatron said walking towards Optimus.

"Never!" Optimus said kicking Megatron and getting back up to the ground.

"Grimlo—Slu—I don't know what to call you both right now!" Optimus said, Cade ran towards Optimus firing at a few Decepticons. "What about Prehistorus?" Cade asked.

"Woah, Jesus!" Cade said moving back after a Decepticon soldier nearly crashed down on him.

"Great name choice, Prehistorus finish off those Combiners!" Optimus orders Prehistorus to kill the two Combiners but is pushed aside by Megatron.

"Don't be intimidated by his size Combiners! DESTROY PREHISTORUS!" Megatron yelled ordering Devastator and Menasor to defeat Prehistorus despite him being ten times their size and having ten times their strength. Prehistorus gets pushed aside by the Combiners and falls to the ground and as the two Decepticons prepare to finish him off, Scorn and Strafe arrive to distract Menasor and Devastator. Prehistorus gets back up and breathes fire into Devastator's mouth burning him from the inside out. Devastator separates from his components and both Mixmaster (the head) and Scavenger (The torso) die from the internal flames. Prehistorus and Strafe then charge at Menasor who is currently fighting Scorn. During the Combiner battle, Megatron seems to have the upper hand but is pushed aside when Optimus slashes him on the chest with his wrist blade. In a fit of rage Megatron aims his fusion cannon at Optimus but Optimus quickly dodges his bullets and with his sword severs his right arm. Optimus then throws Megatron against a pile of damaged cars and pins him down to the ground and begins aggressively beating up to the point where he could die from one more hit.

"What are you waiting for Optimus? Finish me!" Megatron tried to convince Optimus to kill him therefore ending his suffering but Optimus could not repeat the same mistake he did when he killed Megatron the first time and simply walks away.

"Where are you going?" Megatron asked while leaking energon from his mouth and arm stump. Optimus ignores and simply continues walking away ignoring all the Decepticons around him including the Dinobots and Menasor fighting each other but Menasor sadly wasn't able to put up a good fight as he was outnumbered and outmatched being slowly painfully killed by having all of his limbs/components being torn out and killed. Motormaster immediately transformed out of his torso form and landed on the ground.

"NO! NO! Stay away!" Motormaster crawled away from Prehistorus and begged for mercy but the Dinobots ignored his pleas of mercy and tore him to pieces.

"The Combiners have been exterminated!" Soundwave yelled to Shockwave who noticed that Menasor and Devastator are both dead though Long Haul, Hightower, Overload, Rampage and Scrapper were the only components of Devastator to survive.

"DECEPTICONS FIND MEGATRON AND RETREAT!" Shockwave ordered the Decepticons to fall back and take the injured Megatron with them.

"They're retreating!" Drift said.

"What else is new?" Crosshairs asked watching the Decepticons submerging into the water.

"Autobots look!" Sideswipe noticing Optimus coming out of the smoke with Scorn, Strafe and Prehistorus.

"Optimus, some of the Decepticons are still here in Tokyo, should we finish them off?" Hot Rod asked.

"No, leave them be! Let's get out of this city!" Optimus said walking away from Hot Rod and Sideswipe. He activated his jet boosters and flew away.

"What has gotten into Optimus?" Bumblebee asked.

"I don't know kid! It's probably best we don't find out!" Hound said.

"Come on Autobots let's go!" Sideswipe said as all the Autobots and Dinobots began leaving Tokyo and following Optimus.

TO BE CONTINUED…..

So that was Chapter 25 and the sad end of the Combiner Wars, yes I know it seems like the Combiners didn't put up that much of a fight but I wanted to finish this chapter so fast that I ended up rushing it. Anyways I would like to thank Knockout Starscream for coming up with the name Prehistorus for my Dinobot Combiner. Now regarding the upcoming chapters I have sad news both inside the story and outside the story. Inside the story starting the next chapters, a few main characters are going to die, I know I was very kind to the main cast with the only deaths being Dispenser, Mindwipe and Leadfoot but starting next chapter more main characters will start dying and newer Autobots and Decepticons will be introduced. Outside the story, newer chapters won't be posted as early as usual because I'm going to school next week and I'll sort of be busy on YouTube at times. Anyways thanks for reading Chapter 25 and get ready for Chapter 26.
