A hologram of Minerva projects from the bracelet. "Hello, Finn. This is a little project I worked on after our first mission: the Master Brace. It allows you to transform into a Headmaster and combine with the included Transtector." Minerva's hologram summarised. Finn then looks at the white car beside him. "I… I can become a Transformer?" Finn muttered. "To commence the transformation, you hold out your hand and say 'Master Brace'." the hologram said as it demonstrated the instructed movements.

"I need some help here!" Ellie yelled to Finn. He stands up and looks towards Five Deck fighting Ellie. Finn throws his right arm forward and yelled "Master Brace!" at the top of his lungs. He is bathed in a blue light that dissipates, revealing white armour similar to Cogman's and a helmet resembling his head but with an opaque blue visor in place of his entire face from his chin to brow. "This is so math!" Finn said excitedly as he looked at his hands and felt his helmet.

"How do I combine with the thing?" Finn wondered. "To transform, shout 'head on'." the hologram instructed. "Okay!" Finn acknowledged. "Head on!" he shouted. The white car swiftly transforms into robot mode and grabs him.

Automatically, he transforms into a head mainly resembling Bumblebee, but in place of eyes there was a triangular visor much like Yokohama's guardian's. The Transtector places him above it for a neck to emerge from its chest that attaches to Finn. "Transtector connected: Afterburn." Minerva's voice announced on Finn's H.U.D. He runs to the Five Deck and yells "Leave her alone, you jerks!" he exclaimed, pointing at them. "Finn?" Ellie said in surprise as she hung onto Moonheart's face. "Ah! It's the human kid! He transformed!" Megaempress said in surprise.

He first fights with Flowspade by karate-chopping her weapon in half before punching face, cracking her right eye like last time. Afterburn slams into Trickdiamond's shield and knocks her down. He vaults over her to encounter the twins Lunaclub and Moonheart, who were still fighting with Ellie. Moonheart was thrashing around blindly after her right eye was punched in by Ellie. "Mega! Mega!" Moonheart screamed.

"Catch me!" Ellie yelled to Afterburn before jumping off of Moonheart's shoulder. She transforms into motorcycle mode, but her wheels are split in two with sawblades emerging from the tires. Afterburn catches her and destroys Lunaclub's right arm rotor. As he runs past the two he picks up a severed rotor blade as a sword. He charges towards Megaempress and leaps into the air with the rotor blade in hand.

Before she could react, Afterburn sinks the rotor blade into her right shoulder. He lands behind her in front of the entrance to the pyramid. Ellie transforms back into robot mode as the rest of Five Deck came to Megaempress' aid. "[My Lady, are you okay?]" Flowspade asked Megaempress in Japanese. "[That human… he's good.]" Megaempress complimented Afterburn.

The rest of The Voyagers exit the pyramid to see Afterburn standing before them. "Hey, who're you?" Jake asked Afterburn. "Guys, it's me, Finn!" Afterburn answered as he turned to them. "Finn?! You're an Autobot now!" Jake said in surprise. "Thank mom for that. She made me a bracelet that turns me into a head for this Transtector, Afterburn." Finn explained.

"We undid the hack on the guardians. They should be back to normal." Simon informed Afterburn. "Look!" Elisa pointed behind Five Deck. The Decepticons turn around to see all nineteen Japan Guardians and the Swordbots standing before them. "No! My toys!" Megaempress whined.

She grabs her comrades and pulls them closer to her to combine into Megatronia. The destroyed remnants of their weapons reassemble into its sword in their hand. They plunge the blade into the bridge, severing it from the guardians. They turn to The Voyagers and swing their sword, destroying a small portion of the pyramid as she failed to hit them. They duck from the rubble falling but as they do, Megatronia grabs Ellie.

"Help!" Ellie cried. "I'll save you!" Afterburn declared. He is kicked in the abdomen, ejecting Finn from the Transtector. The armour disappears as he tumbles along the ground. He turns to look at Megatronia lifting Ellie into the air.

The combiner forcibly transforms her into vehicle mode with their hands with the rear half split apart to the sides. "What's she doing?!" Finn wondered. Megatronia places Ellie on their chest, causing energy to surge throughout their body. The combiner starts to increase their mass at a slow rate. The remnant of the bridge she stood on starts to crumble as they grow.

Eventually, they sink into the bay, only to have their head emerge from it and towers over the Transformers and humans alike, but not as tall as the pyramid before them. They raise their sword into the air, intending to finish off The Voyagers, only to be shot by a mortar round from the Ursa Detroit. Megatronia is thrown into the city back on land. Seamus, Springer, and Fallback watch from the helipad before the human disappears in a column of light to the surprise of the two Autobots. "Ah! What's happening?!" Seamus said before disappearing.

Soon after, the rest of the team at the pyramid are also taken away by the light pillar. The smaller Voyagers members are teleported into the bridge of the ship as they watch Megatronia laying waste to the city. "What happened there? How did she grow so big?" Finn wondered. "Nevermind that! We need to fight her!" Jake said. "How? She's the size of a medium office building!" Simon wondered.

A hologram of Minerva appears in front of them behind the controls. "The Ursa Kildare has detected a gigantic hostile entity. Would you like to commence transformation?" the hologram asked them. "The ship can transform?! We can take her on! If this ship is huge, it'll be even huger when I transforms!" Finn said excitedly. "Honestly I'm not that surprised. I saw a giant finger somewhere when I looked around the ship. "I say we transform! We have to save the Prime, or else Optimus Prime'll axe us!" Chad suggested.

"How do we transform?" Elisa asked the hologram. "All registered ground members must shout 'transform: Ursa Kildare' to commence transformation." the hologram instructed. "You heard mom; let's transform!" Finn declared. They stood in front of the console and faced the window. "Transform: Ursa Kildare!" they all shouted.

"Voice recognition confirmed. Now transforming." the hologram confirmed before disappearing. The ship starts quaking as all entrances to the bridge seal off. The hull splits apart as the rear end raises itself. Emerging from the split hull was a gigantic body, a platform that held a portion of the bridge where The Voyagers stood, and a partially-built head that bore a plate-like helmet with Finn's ears and the Voyagers logo on its forehead, a hollow cavity in place of the eyes and a structure between that and a mouthplate that can only be described as a "handlebar moustache.", like Jake's jowls. The body rises up as the helipads where Fallback and Springer stood upon formed shoulders.

"What in the blazes is going on?!" Fallback panicked. Springer transforms into helicopter mode and carries him away with his magnetic grapples. Its hands emerged with long hook-like fingers. The Voyagers watches as all this happens around them. The entire bridge then moves up the torso and into the head where the windows formed the visor eyes of the robot.

The consoles slide away from the window as six pedestals raised each member from the floor. "This is just like a Megazord!" Simon said excitedly as he looked around. "What's a Megazord?" Finn asked. "I'll tell you later." Simon said. Megatronia stops her rampage to gaze upon the inert Transformer floating in the bay with its legs still formed as half-hulls.

"[What is that?]" Megatronia wondered. "Artificial gravity gyroscope: online. Motion tracker: online. Speakers: online. Do you want to make an announcement?" Minerva asked Finn. "Yeah I do, give us back Ellie!" Finn's voice shouted to Megatronia. Megatronia runs at Ursa Kildare as it sat in the bay. "Where are our weapons?" Finn asked the hologram.

"Sending Night Sword." Minerva said. All the way from Ooo, a railgun emerges from the dock where Ursa Kildare launched from. It fires a round eastwards to Japan. A mere minute later, the sword crashes through Megatronia's left shoulder and into Ursa Kildare's hand, revealing itself as an enlarged Night Sword. "It's a giant Night Sword!" Jake said excitedly.

"That's the ticket! And we're going on a trip to Slashtown!" Finn exclaimed. "Your movements control Ursa Kildare. I suggest you move in synchrony." Minerva advised. The Voyagers run towards the downed Megatronia and stay in place thanks to an omnidirectional treadmill beneath them. Ursa Kildare swims across the bay and swings by Megatronia and hold outs its sword on its left hand to do a swim-by slash to their legs. Megatronia is knocked back into the city as Ursa Kildare swivels its hulls backwards to form legs that step onto dry land, making its height just a few metres taller than Megatronia.

It comes at her with the Night Sword dragging across the road. Megatronia stands up and face them with their Ellie-chest out as Ursa Kildare swung its sword at them. Ursa Kildare pulls the sword away from her and lodges it into a building. "What was that for?" Jake asked Finn. "We can't hurt Ellie!" Finn said.

Megatronia then swings her sword across Ursa Kildare's chest, causing it to crash into a building. "We have to find a way to defeat that thing without hurting Ellie!" Finn said. "I think she's the reason Megatronia is so powerful and huge! We need to pull her away from them!" Simon advised. "How are we supposed to do that? One wrong move and Ellie'll get slashed!" Elisa wondered. A groundbridge appears behind Megatronia for the R.F.G. Type Prime to emerge, blaring its jingle and carrying Ishinomaki's guardian and the Swordbots as they stood on the main train and their personal cars.

"Ore Sanjobot!" Gekisoumaru announced. The train zips around Megatronia so fast that she fails to strike it with their sword. "Guys, keep them busy!" Finn's voice shouted from Ursa Kildare as it got up. It swings the Night Sword on her back for them to turn around. Ursa Kildare grabs onto the cowl of Ellie's motorcycle mode and yanks her off.

In its hands, she shrinks down to normal size and transforms into robot mode. "Ugh… what happened?" Ellie wondered as Ursa Kildare put her on its left helipad-shoulder. "We'll explain later." Finn's voice said. "Finn… wha…?" Ellie muttered. "[You…!]" Megatronia said in disdain before the train rams through Moonheart.

"Let's finish this! I've always wanted to destroy an enemy in a Megazord!" Simon said excitedly. "Diagonal cut, everyone!" Finn instructed. They mimic swinging a sword downwards diagonally from the right which Ursa Kildare follows, slashing Megatronia across their chest. Megatronia falls to her knees and explodes as Ursa Kildare turns away. "Aw, I wanted to see the explosion." Jake whined.

"Cool guys… don't look at explosions." Simon said as he pushed up his glasses. On the ground, the injured Five Deck lay on the ground as Jetfire emerges form a groundbridge. "Ohayo, ojiisan." Megaempress said nervously. "It's five in the afternoon!" Jetfire scolded. He then carried everyone into the portal

Ursa Kildare is returned to the bay for The Voyagers and Ellie to approach T-AI after she parked the train in front of the dock. "I can't thank you enough for what you've did for this country." T-AI thanked Finn. "It's all in a day's work." Finn said. "What are you going to do now?" Chad asked her. "I'll get the people back to the surface, and find that missing A.I." T-AI answered.

"Hope we meet again!" Finn said. T-AI, the Swordbots and Ishinomaki enter the train and fly into a groundbridge into the sky.
