"What in the world is that?!" Farmworld Finn panicked. "Jake, step on it!" Finn told Jake. The two Jakes gallop with their Finns to safety as the massive Combiner tears up the desert around it. They soon reach the dune and find Gross standing in horror at the sight of the Combiner as she held her umbrella. "Finn, what happened in there?" Gross asked the Finns.
"Morocco refuelled this thing with energon!" Jake exclaimed as he pointed to the Combiner. "Aunt Gross, do you know what this thing is?" Farmworld Finn asked Gross. "Morocco called it Devastator. He buried it under the hill and tried to get it up-and-running. I've never seen it active before." Gross answered. Devastator starts to walk westwards towards the coast.
"Finn, you've seen something like this before, right? Please tell me you know how to stop this thing!" Farmworld Finn asked Finn. "The last time we fought something this big, we piloted a battleship mom built!" Finn answered. Farmworld Finn turns to Gross. "Huntress, take Aunt Gross far away from here!" Farmworld Finn instructed Huntress. At that moment, a spacebridge opens up on the dune next to them.
Stepping out of the spacebridge is Optimus Prime and the Dinobots. "This isn't Little Cybertron." Optimus Prime said. He then gazes at Devastator laying siege on the desert before it spots the Dinobots. Devastator lets out a roar as the Dinobots charge towards it. "Optimus, I thought you were going to that other Megatron's universe." Finn said.
"I was, but it seems I instead entered the universe that you were going to. I only saw you a few seconds ago." Optimus Prime answered. The Farmworld inhabitants look up at the Autobot leader with looks of amazement. "Optimus, we had a run-in with Doctor Morocco and C.Y.L.A.S. again. They just ran the moment Devastator woke up." Finn explained. Optimus Prime scans the area and sees C.Y.L.A.S. and three MorBots driving through the desert south from Devastator.
"I shall help however I can." Optimus Prime told Finn. He then transforms into semi-truck mode. "Finn, other Jake, Gross, get in." Finn told the three. They enter Optimus Prime with Finn and Jake sitting at the front, and the other three sitting at the back. "Let's roll out!" Finn exclaimed.
Optimus Prime revs up and speeds towards the escaping fleet as the Dinobots engage Devastator in their dinosaur alternate modes. Strafe the two-headed Pteranodon shoots at Devastator's back with wing-mounted machine guns. As Devastator tries to swat him out of the sky, Grimlock chomps onto Devastator's left crane arm. In retaliation, Devastator swings two wrecking balls from their left crane arm into Grimlock's face, and then into Spinosaurus Scorn as he threw himself at Devastator. Slug the Triceratops charges towards Devastator's face, but is soon sucked into Devastator's vortex of a mouth, jamming it before Devastator ejects the Dinobot from their backside.
Optimus Prime and the adventurers continue to pursue their targets fleeing the desert. Morocco sat on C.Y.L.A.S.'s front passenger seat. "How much longer until we get to the border?" Morocco asked C.Y.L.A.S. impatiently. "I can't go much faster. I'm sure your Las Vegas contact can wait." C.Y.L.A.S. communicated to Morocco via the radio. "It's unbelievable that they renamed the city just because some letters got scratched off the sign." Morocco moaned.
C.Y.L.A.S. adjusts his rear-view mirrors to see Optimus Prime catching up. "I don't believe it…" C.Y.L.A.S. said in disbelief at the sight of Optimus Prime. Morocco looks at his side's rear-view mirror and is surprised at the sight of Optimus Prime. "MorBots! Get him!" Morocco commanded his MorBots through C.Y.L.A.S.'s radio. The MorBots slow down and transform into robot mode, preparing to strike.
They fire lasers from their front-wing blasters at Optimus Prime, who defends himself with a holographic shield shaped like the Autobot insignia. He rams through one of the MorBots to chase after C.Y.L.A.S. and Morocco. The MorBots get back up, but are decimated by Slug landing on them after being thrown by Devastator. "The Autobots are supposed to be gone!" Morocco exclaimed. "It just had to be Optimus Prime." C.Y.L.A.S. groaned.
Suddenly, C.Y.L.A.S. swerves out of control and transforms into robot mode, ejecting Morocco. C.Y.L.A.S. gets up and finds that the tire on the back of his left thigh is punctured from a gunshot. Optimus Prime ejects the adventurers before transforming into robot mode, deploying his energon swords from his arms. "Silas!" Optimus Prime exclaimed. "Optimus Prime. A displeasure to see you." C.Y.L.A.S. taunted.
Morocco picks himself up from the dune and dusts himself off as the four adventurers face him. "How did you get Optimus Prime?!" Morocco questioned them. "What's the deal with the big blue robot?" Farmworld Finn asked Finn as he readied his arm blade. "He's the leader of the Autobots, those good Transformers I mentioned earlier." Finn answered. "He's a pretty big deal, not gonna lie." Jake added.
"Normally I let others to do the fighting for me." Morocco said as he rolled up his sleeves. His arms then split into multiple bladed appendages. "But with this new Pretender body, I am unstoppable!" he exclaimed. "Let's see if that's the case." Farmworld Finn said. "By slicing your face off!" Finn added.
The two Finns and Jakes rush towards Morocco and throw everything they have at him. Gross flees to a nearby dune and watches the battles rage around her. The Finns deflect every slash from Morocco's bladed appendages, allowing the Jakes to pull his legs, tripping him over. When the Finns are about to plunge their arm swords on the fallen Morocco, he rolls over and swings his blades at them. Optimus Prime swings his swords down at C.Y.L.A.S., who parries it away with his hand scythes.
Suddenly, C.Y.L.A.S.'s left eye is shot off by a bullet. "My eye!" he screamed. Optimus Prime looks to the source of the shot and sees a figure atop a dune walking away. He turns back to C.Y.L.A.S. rubbing his eyes, and them plunges his swords into his abdomen, slicing him in half. C.Y.L.A.S. collapses and shuts down.
The Finns and Jakes continue to battle Morocco, but are soon exhausted from fighting in the desert heat. "One advantage to having a robotic body is that I don't get tired!" he taunted them. The adventurers start to slow down in their attacks and are pummelled by Morocco. "So… hot…" Jake panted as his Farmworld counterpart rested on him. "Water…" Farmworld Finn moaned.
Morocco stands over them menacingly, with all his blades pointing to them. "I must say, you made today quite fun. I missed the thrill, but I can't say the same about you four." Morocco mocked them. He raises his blades, preparing to impale the adventurers, when his eye blows out from behind. His arms droop and he collapses. The adventurers then look upon a mysterious cloaked figure wearing an elk helmet.
"Hey, Finn. Hey, other Finn." The figure said with a familiar woman's voice. Finn looks up and sees the human counterpart of Huntress Wizard, armed with a sniper rifle. She takes her canteen and pours water into the mouths of the adventurers. "Huntress? What are you doing here?" Farmworld Finn asked Huntress. "Your aunt told me everything. She to blow moustache guy's robo-brains out." Huntress answered.
The Dinobots soon get the upper hand over Devastator with greater numbers, eventually tearing the Combiner apart. Their components are either chomped to pieces, or escape into the desert. "It's over." Optimus Prime said as he retracts his blades. The adventurers and Gross get up and look around to see C.Y.L.A.S.'s inactive body and Morocco's remains. "I never did get to bring that energon back for Junktown." Farmworld Finn said.
"Don't worry, I'm sure you'll find more energon somewhere." Finn assured. "Thanks, man." Farmworld Finn thanked Finn. "Finn, let's get back to the highway before the multiverse bridge opens up." Jake said to Finn. "Right, bro." Finn acknowledged. Optimus Prime transforms into truck mode as the Dinobots gather around.
"Come on, Aunt Gross. Let's take you home." Farmworld Finn said as he extended his robot hand to Gross. The five steps inside Optimus Prime as he starts his engine. "Bye, Finn! I'll see you on our next date!" Huntress waved to them. Farmworld Finn blushes as he waves back. Optimus Prime drives westward towards Junktown as the Dinobots follow him.
Huntress walks away from the desert, leaving behind the robotic corpses. After she's gone, C.Y.L.A.S.'s remaining eye opens up and glows red once more. The head detaches from its body and rockets away into the sky. The crushed MorBots' visors light up red, and disassemble into a metal cloud, reassembling into a single red MorBot. The red MorBot transforms into a half-track truck, following C.Y.L.A.S.'s flying head.
That evening, the adventurers return to Finn's home with Optimus Prime and Gross. They disembark from Optimus Prime as Finn's family came outside to greet them. Farmworld Minerva sees Gross and hugs her. "Welcome back, doc." Minerva told Gross. Farmworld BMO and Farmworld Finn's little brother run up to Farmworld Finn excitedly.
"Did you get anything from your adventure?!" Farmworld BMO asked Farmworld Finn. "Sorry, BMO. I wished I did." Farmworld Finn answered. A blocky blue hovercar soon arrives and Farmworld Moe exits from it. "Hey Finn, you left your donkey at my factory." Moe said as Bartram pokes his head out of the hovercar's window. "Bartram! Sorry, I forgot all about you!" Farmworld Finn said as he ran to his donkey.
"By the way…" Moe said. He hands Finn a canister of glowing energon. "It's energon!" Jake said as he and Finn walk up to Moe. "Where did you get it?" Finn asked. "I synthesized it from the energon in those drones Morocco left behind. It's the least I can do after what happened." Moe answered.
"Thanks, Moe. This is gonna help everyone in Junktown!" Farmworld Finn thanked Moe. Finn looks back at the timer on his robot arm. "We've gotta go back to our universe. We'll come by and visit again." Finn told Farmworld Finn. "It's been awesome getting to know you, Finn." Farmworld Finn said. They then fist-bump each other.
"Take care of Finn, alright?" Jake told Farmworld Jake, who licks his face. Finn, Jake, and Optimus Prime drive away from the farm towards the highway. Farmworld Finn and his family waves to them as they drive into the night, hoping to see them once more. The Dinobots are waiting at the highway when the multiverse bridge opens back up. Optimus Prime drives through the multiverse bridge, followed by the Dinobots stomping into the portal.
The adventurers and Autobots emerge into their home universe through the not-at-all-destroyed multiverse bridge arch. There, they are met by a happy BMO who looks up at Finn and Jake. "Finn, Jake, you're back!" BMO greeted them. "Hey, BMO. Anything exciting happen lately?" Jake asked BMO. "Not really, but I paid a visit to Football today. She told me to say hi. Hi!" BMO answered.
"That's… great, BMO." Finn said. "Come on, Finn. Let's report back to your mom." Jake said. "We'll see you later, Optimus. Sorry you didn't get to your destination as planned." Finn told Optimus Prime. "It is alright, Finn. I only hoped to see Megatron one last time. Now, I shall return to Cybertron with the Dinobots. Farewell." Optimus Prime told Finn. The two parties part ways; Optimus Prime and the Dinobots walking back to the nearby spaceport, and Finn and Jake returning to the Hub Dome.
In the vast darkness of space, a massive, blocky white ship emerges from hyperspace; the Lost Light. Captaining the ship is Hot Rod, but he looks vastly different from when The Voyagers met him, having a different body-type and an entirely-red paintjob. "Bloody hell. We did it." Hot Rod said without his French accent. "We did it!" Hot Rod cheered excitedly. Looking up to Hot Rod among his Autobot crew is a smiling Megatron, bearing the Autobot insignia on his chest.
