After some walking, the group came across a short service tunnel, leading downwards. Shining the Light Crystal around, R.D. found some corroding signs, informing them it was a service tunnel into a now-defunct subway system.

"We have to go this way," Ileyna said, pointing down the tunnel. R.D. didn't contest her statement. As they made their way down the path towards the locked doorway, R.D. fell back a few steps, then leaned over to talk to Matt.

"The other two are on their way, aren't they?" he asked quietly, so that the two children wouldn't be alerted.

"Yeah," Matt muttered. "Polonaise and Pizza."

They would soon be fighting the past J. Guy had recounted how J was eventually purified by Kaidou, a child from another planet with powers similar to Mamoru. J and GGG then joined forces to shut down the Primevals, and eventually, the galactic monster called the Z-Master.

How would this fight turn out? Good question. But he was going to give a hell of a show.

R.D. nodded. "Yeah. Just do what you have to with Pizza. I'll make sure this Polonaise guy doesn't get in the way."

"Are you guys gonna unlock this or not?" Ileyna asked, looking over her shoulder at the two of them. They were standing in front of the door, which had a large, rusty padlock on it.

"Yeah, yeah, hold on a sec," R.D. muttered as he drew a Phase Blade. He slashed the padlock in two, causing the door itself to swing out slightly, its hinges making a rusty grating squeak. R.D. peered through the opening, seeing a tunnel with low lighting. Train rails were set into the ground in four rows, two spaced out a bit from the other two. "Alright, looks clear," he said, easing out into the subway tunnel.

It didn't take Seril long to catch up--the first Reaverbot was avoided in the same manner as Gatz, and she alternated between disabling the remaining Reaverbots with her Dragonblade, and simply avoiding them outright. It was only a couple of seconds before Seril had met with Gatz again as he leaned against the wall.

Matt peered out into the dusty and forgotten subway tunnel. He cast a ball of flame, and it hovered before him, flooding away the darkness. "Let's go."

It took them several more minutes of searching within the old subway tunnel. R.D. found himself constantly on the lookout as the two children guided them deeper underground, concentrating on the Zonder Core and the Omega Essence within it.

"Whoa, look at that," Ileyna said, pointing at something in the distance. R.D. held up the Light Crystal to shine it further down. Off to the side in the tunnel was a large gap in the wall, dark and foreboding. "The Core went that way, too," she continued. "Its lower than before."

"Wonderful," R.D. said, motioning for them to stay back. "Let me check it out."

He approached it warily, stowing the crystal away and using light energy to illuminate the area while he held a Phase Blade in one hand. The amnesiac peered into the darkness, his gaze drawing downwards. What he saw was an expansive, open shaft, as if something had burrowed through. He made a low whistle, one that echoed in the shaft. "Great, looks like we're flying, now."

"While I would recommend flying," a voice suddenly spoke up in the darkness, causing R.D. to recoil backwards, "I am afraid that this game of yours is coming to an end."

R.D. leaped backwards as a figure of twisted metal rose up from the entryway of the cavern. It molded itself into a caped man with a familiar, bloody-looking helmet. "My name is Pizza," the newcomer said coolly. "I am here to bring you to an end."

Matt caught sight of the Machine King as well. That's Pizza? "Fuck!" He threw out his arm, summoning his armor.

Then something hit him, smashed into his body at what felt like a hundred miles of hour. He cried out at the sudden thundering blow, flew into the tunnel wall with a crash and a crumble of debris.

"Matt!" Mamoru shouted.

The blur that had hit him stopped, and now they could see what he was-a uniformed man, with what looked like a massive, mechanical caterpillar replacing his head, the end draping down his back. The figure produced a rotund pipe and blew into it, exhaling a blast of smoke and a shrill train whistle.

"You also face Polonaise, the final Machine King," he said. "Your combined strength is no match for us."

"Matt!" Ileyna cried, running up to him despite the danger of two Zonderians present.

Well, this was looking worse by the second. R.D. grit his teeth as he looked between the two remaining Machine Kings. He knew that Matt had to face off against Pizza, as Soldato-J had told Matt before, so that means he had to take care of Polonaise. But could he do it without Helena and Hugo's help?

Oh well, I don't have a choice, he thought. "Ileyna, Mamoru, you have to go after the Core!"

R.D. flung his arm out as he yelled, and particles of light drifted down onto his form, molding and brightening into the cobalt and silvery-blue Bound Armor of the King of Dragons. As the visor closed down on his face, R.D.'s eyes flashed yellow as he stared at Polonaise. With a yell, he threw himself at the train-themed alien.

Pizza took in the sight of Matt and Ileyna at the wall opposite of him. He began to walk towards them, holding one hand out at his side. "Its a shame you're not on your feet, boy," he said. "I was hoping for an actual fight."

Slumped against the wall, Matt carefully flattened his hand. Then: "Air Cutter!" He sat up, chopping with his hand, unleashing a wave of razor wind at Pizza.

Polonaise lowered his pipe, and in a blur, he moved again, a short distance away to avoid R.D.'s tackle. He lowered his shoulder at the boy and launched himself at great speeds.

Pizza narrowly dodged the attack as it was thrown at him, looking surprised. Then, suddenly, he smiled. "Maybe this won't be so disappointing after all," he said.

Ileyna tugged at Matt's hand. "Give me the pendant," she said quietly, looking at Pizza as the Zonderian readied himself for battle. "I'll get the Essence while you take care of these guys."

R.D. could feel his armor fracturing under the sudden force of the attack, and he struck the wall hard, cratering in it. Coughing up a bit of blood, R.D. growled as he stood back up. "Think you're tough, eh?" he muttered, bringing out the Phase Blades. Crossing them over between the hilts and crystals, he made a single scissoring motion as he activated them, transforming them into the Phase Scythe. Swinging the massive blade around to bear, R.D. readied himself for battle.

R.D. glared angrily as lashed out with Lumiya's power, infusing it into the Dragon King Armor. The red gemstones set into the armor slowly changed color, turning into a brilliant emerald green color. Light flickered in the three chest jewels and the forehead jewel, as short, harsh lines of light formed an angular G as he harnessed the power of the G-Stone's energy.

Matt stood up, pressing the pendant into Ileyna's tiny hands while keeping an eye on Pizza. "Get going."

"Come on!" Mamoru said. He took Ileyna's hand and pulled her toward the shaft.

Matt beckoned with his armored hand. "Come on. Let's see how you dance."

Polonaise seemed distracted by the sudden power R.D. displayed, but his attention snapped elsewhere, as Mamoru and Ileyna ran for the shaft. "Pizza! Stop the children!"

R.D. knew a chance when he saw one, and immediately opened fire at the Zonderian. Snapping his wrist forward, he activated an arm cannon and opened fire with a charge shot, firing a blast wave of plasma at Polonaise.

Pizza's head shot around to look at the escaping children at Polonaise's command, and frowned. With incredible speed, he chased after them, quickly gaining the lead. Ileyna shrieked as Pizza appeared in front of the entrance to the shaft, his hand becoming a wicked-looking talon as he swung it forward at them.

Seril merely nodded. "Let's use it, then."

Matt's hand crashed into Pizza's face, smashing him into the wall before he could complete his attack. Electricity crackled down his fingers, and he unloaded a huge burst of electricity through the Machine King's system. "Stun Voltage!"

Surprised, Polonaise raised his arms to guard R.D.'s shot, as if the wheel-like structures covering them would serve as shields. The shot was too fast and powerful, though, and the Machine King hit the pavement with a clatter of metal. He pushed himself back up with a growl and lashed out his arm-the wheel attachment unwound like a clunky snake and lurched at R.D., seeking to restrict him.

"Gwaaahh!"

Pizza bellowed and fell back as lightning coursed through his system, electrocuting him fiercely as he was flung into the shaft itself. Seeing their chance, the two children quickly made their way inside before stopping at the edge. Matt needed to distract Pizza, who was quickly recovering and landing on a rocky outcropping, looking up at them.

"Hah! Got you!" R.D. said in satisfaction as the blast wave struck Polonaise. However, he suddenly noted the metal extensions lashing out from the smoke of the explosion, and couldn't react in time as the wrapped around him. "What the hell!?"

He struggled to get free--with his arm pinned down like this, he couldn't use his Phase Scythe to cut through. Luckily the G-Stone energy inside of his armor prevented the Zonderian from absorbing his armor to heal himself.

The transformed dragon merely shrugged in response. "I'm unfamiliar with the technology of your kind," she said. She thought a bit. "Why not check the system for a log of recent activities in the system? Maybe Juno inputted some commands to redirect or disable the power."

A bit more thinking caused her to frown. "There's also one Sub-Gate on an island to the south of Kattelox," Seril informed the Servitor. "There's a cavern system connected to that ruin, and within those caverns is a Pillar of Dawn. If the power is out there, then someone may be trying to interfere with the Pillar. See if there's anything amiss there as well."

With a shout, Matt thrust his hand at Pizza, and pillars of earth sprung out to smash into the Machine King. "Get outta here!" he shouted at Ileyna.

Polonaise yanked R.D. toward him, giving him a window to stand back up and unload another charge attack.

Meta allowed Awai to pick her up in his arms and held on to him tightly enough to make sure she was secure in place, but not tightly enough to make her feel uncomfortable about the situation. As they blasted off into the setting sun in the west, she looked at Awai sternly. "Just don't be getting any ideas from this, big guy." She muttered loud and clear. Her own thoughts were focused on the near future, and also the very far future indeed. I wonder what this Serenade figure is like.

Pizza launched off of the outcropping with incredible speed as the attacks against him were initiated, his cloak acting like wings. Soaring through the air, the Machine King's attention was focused solely on Matt, and he streaked in with a foot leading the way.

Seeing her chance to move, Ileyna opened herself up to her powers of Purification, alighting in the bright blue aura, with the wings and halo and shield. Quickly, she stepped off the edge and began her descent down into the darkness, apprehension in her heart. Now, they'd be going it alone.

"Oh no you don't," R.D. growled as he dismissed his Dragon King Armor--the new gaps between his body and the appendages allowed him to slip out of the bindings. Quickly summoning the armor back, R.D. raised the Phase Scythe over his shoulder and swung, firing a blade beam at Polonaise. "Kougenjin!"

Shit! Pizza's aerial kick hit home, knocking Matt to the wall. He slammed against it and leapt back off. He forgot how fast this guy was! Only one element worked here...

"Volteccer!" Surrounding himself in a spherical field of electricity, Matt threw himself against the wall, bouncing up, about the abandoned subway at high speeds, directing his quick riccochets at Pizza.

Polonaise cried out as the blade beam smashed into him full force. His grip dislodged as he went flying again, tumbling onto the broken set of railways.

"Not bad, human," he remarked, rising again. "But I'm not through with you yet."

He blew on his pipe and expelled a greater amount of smog, cloaking him within.

"Oh, dammit," R.D. said, looking about the smog as he tried to search for his foe. "Not this shit again."

Quickly, R.D. switched his Visor settings to another setting he had gotten from Samus. His sight was suddenly painted in hues of blue and black, searching for a heat signal from the Zonderian. There was a sudden flash of yellow-red as Matt blasted about the structure, the heat signal from him going off the scale thanks to the electricity empowering him.

But to his visors, Polonaise and Pizza were nowhere to be seen. What the hell?

Unseen by R.D.'s Thermal Visor, Pizza was quickly darting to and fro within the tunnel, deftly avoiding each ricochet from Matt. He was grinning. With a careful move, he got Matt's ricochet to bounce back into the shaft, then quickly followed.

Darting into the shaft, Pizza went on the offense, spreading his cape wide open as a blast of wind shot out of it, headed for Matt.

"Shit!" Matt cancelled his field just as Pizza unleashed a gust of wind, forcing him down the shaft. "Oh no you DON'T!" Turning on more power, a burst of lightning shot him back up at the Machine King, and he tackled him head-on, leading the way with a monster headbutt into Pizza's helm.

Something heavy smashed into R.D.'s side at high speed-another attack by Polonaise, but from where?

"Gyahh!" R.D. smashed hard into the stone floor as the attack slammed against his side, easily knocking him down. He quickly recovered, rolling on his side into a ready stance with his sword as he switched to the X-Ray Visor.

Even still, he could detect nothing from the Zonderian. Cursing, R.D. switched back to his helmet's normal mode, clouding his sight up with the smog once more. Looks like he'd be relying on his other senses this time.

Moments before Matt could strike, Pizza's form seemed to blink out again. "Hah!" the Machine King taunted. "Too slow, too slow!"

He shot back in from behind, leading the way with his fist. Rapidly, he began to attack using different angles, striking repeatedly at the white-coated boy.

Matt tried to block as best as he could, but it was no use-Pizza was too damn fast, hitting him from all angles. Not enough electrical energy to keep up...but maybe...

Just as Pizza came in for a claw slash, Matt seized his wrist with the Genesis Arm. He smirked as the Arm unleashed an aura of light. "Gotcha!"

"It seems you rely heavily on that armor of yours," Polonaise remarked from the blackness. "It doesn't matter if I can't absorb it. Once I strip it from your body, you will be nothing but a weak human."

"Tch. And you guys just sit in your little hole, letting Zonders do your dirty work," R.D. remarked in return, though he couldn't see the Zonderian. "And even then you don't succeed. Don't preach to me about being weak."

Pizza made a noise of surprise as Matt grabbed a hold of him, causing light to flare out from the boy's arm. Pulling himself free, Pizza landed on an outcropping above Matt, glaring through the helmet, though his eyes could not be seen. "Like that G-Stone cyborg, you seem full of surprises, boy."

Meta let go of Awai with her gauntleted right hand and held it raised up to shield her eyes from the rays of the sun as the Light Balance flew up above the clouds. She shivered slightly, it was rather cold up there, and dew from the clouds stuck to her skin and clothes and pieces of armour. She had little time to heed Awai's words, as she felt a most extraordinairy feeling overcome her, like she was breaking apart but yet remaining whole, and it made her psyche twist and tingle. Arriving in the Nexus, she let out a gasp and breathed heavily, again shivering. "What was that?" She asked aloud in wonder, but it didn't matter. It was rather clear once she glanced around. "Th-this is...? Serenade's residence, I presume?" She muttered, looking at Awai's face, expecting an affirmative reply from the green-haired man.
