Mewtwo was an imposing force. Sometimes Ash forgot this, even if he was once at the receiving end of the ultimate Pokémon's attacks. But when he was reminded, boy was he reminded.

The cave around them shook, as both dark user and man-made Pokémon clashed in an explosive fresco of psychic and auratic power. When one would attack the other, the other would dodge. Ash looked on in awe, Riley's weight on his shoulder all but forgotten. A vine whip attack took advantage of his stunned nature and snagged his ankle. His feet were pulled out of him and suddenly Ash was being yanked across the room.

Ash let out a yelp when he went down. Scraping the dirt floor as he was dragged, dust and soil got into every crevasse between his skin and clothing. He could hear his friends and family scream as the venusuar, they all forgot about, pulled the dark-haired trainer across the room.

"Pikapi!"

Ash barely had time to blink, when his electric mouse leaped over his head. Pikachu's body was alit with a thin veil of white glow. A quick attack. His partner's tail gained a shiny sheen of metallic nature and with a war cry sliced the vine off Ash's leg. Freeing the dark-haired trainer. Pikachu landed gently on Ash's belly, his big black eyes looking on in worry.

"I'm okay, good job," Ash said, scrambling to his feet.

The dark-haired trainer looked back at his friends and family. Riley had crumbled to the ground without Ash holding him up. Goh and Riley's Lucario were tended to him. Amanda was looking at her phone, no doubt trying to find a way out of here. Sir Aaron was looking at him, silently asking if he was alright. Upon Ash nodding, the knight's gaze went back to the battle unfolding before them.

The Venusaur growled and Ash suddenly remembered the fight he had found himself in. Pikachu leaped out of his arms and took a defensive stance in front of him. Ash grunted in determination. They were going to have to fight their way out of here. Well, challenge accepted.

Both human and pokemon entered the fight with the same amount of vigor, strength and determination that they did every battle. All of it! Every ounce of Ash's heart and soul was put into this, because this wasn't a tournament, no trophy or title was on the line, it was his family and friend's live, and there was no more important fight to give you're all in to. Blows were traded and moves clashed at lighting speed.

Throughout the fight, Ash couldn't help but notice that the Venusaur's eyes never changed. They remained silver dollar moons in the middle of an empty inky void. Anwir never let go of his control over the grass type. All while still facing Mewtwo head on. How was he doing that? How was he controlling the soul of this Pokémon at the same time not being killed by one of the most powerful Pokémon in the world. And if he could do that?

What else could he control?

Venasuar let out another earth-shaking roar, raddling the walls…and…A cold chill ran down Ash's spine, and he whirled around, looking at the wall behind his family.

"Get out of the way!"

For once in his life, Sir Aaron was frozen in his place.

His eyes, ears and even aura sense were currently being overloaded with fight happening in front of him and the rock of mount moon. The Knight was trying to keep an eye on each of his charges. Lucario was just as tense as he was. pacing between them and the rest of the conflict. Amanda trying to find a way out of the tunnels. Ash had found himself in a fight with the grass titan. Goh was making sure that Riley wasn't perishing on the impromptu battlefield. Riolu doing the same for his nephew's auratic partner.

Sir Aaron looked over his nephew with worry. The young man was in worse condition then the knight had thought. Skin pale and mulled with bruises and small cuts. Lagoon blue eyes almost glazed over with an exhaustion that could only be described as close to death. The knight knew he could heal Riley as long as there were no internal wounds but first, they had to get out of here.

There was a heavy rumbling noise and soil and pebbles rained down on them from above. Amanda let out a rather explosive sneeze when the dirty dust hit her nose. Something about the sound coming from the walls made his stomach coil.

"Get out of the way!"

The call of the young lad was quickly drowned out by the wall behind them cracking and falling away. Dust and rubble spilled onto them, as Sir Aaron began to push the group out of the way of the large, corrupted soul what was tunneling towards them. From the wreaked wall burst fourth a large rock wielder in snake form.

"An Onix?!" Goh shrieked.

The Rock wielder reared up as tall as the ceiling allowed. A low guttural growl bubbled from the stoney maw. A sound which quickly echoed throughout the cavern as more and more Onix broke out of the walls adding to the chaos. Despite the growing mayhem, Sir Aaron focused on one thing. Their eyes. Each set was exactly the same. Their whites were dyed black, with clouded irises and pupils. A glazed appearance settled in them. He couldn't see into their souls, for their spirits were no longer theirs.

With a wave of battle cries, the stone wielders began their assault. Lucario and Umbreon were quick to jump into the fray with Sir Aaron raising a shield to put a barrier between the attack and the children. They held back the force of Onix, best they could, and quickly they were joined by Roserade and Pichu. However, while the knight had great faith in the Pokémon's skill, they couldn't last forever, especially with the vast numbers of their foes' forces.

Sir Aaron's mind cycle through plans and battle tactics. He needed a plan. The most obvious one being cutting off the serpent's head, and by that he didn't mean the Onix. It wasn't their fault they were being controlled. Anwir was the one making them fight. Take him out. Cut off the head. And everything would fall apart. But the currently the knight was stuck, if the aura shield were to fall, and the onix break through the blockage the other Pokémon had set up…

"Lu."

The knight looked toward the noise, surprise filling his body at the sight of the young Lucario. Wounds littering the pelt of blue and black fur, yet he stood tall in defiance of the pain. An understanding was shared between Sir Aaron and his nephew's partner.

"You'll hold up the shield?"

"Lu" The aura Pokémon gave a single nod.

The shield was passed from hand to paw, and in that small flicker between the hand over Sir Aaron stepped beyond the protection of the gleam blue veil. The feeling of a warm hilt in his palm gave him much comfort in the discourse surrounding him. He glanced down, seeing a blade forged of his own soul in his grasp.

Sir Aaron?

"Protect the children," The knight ordered.

Lucario nodded, returning his attention to the opponent in from of him.

Sir Aarorn darted through the chaos, his blade clashing against stone as he warred away stray Onixs' attacks, looking for a clear shot at the head. And when he found it, he acted. Anwir shoved Mewtwo away with a title wave of poisoned power, the Pokémon steadied himself quickly, but Sir Aaron acted first. The knight raised his soul blade over his head and swung down from the shoulder. A harsh hum broke from the energy blade, and a shockwave echoed from it. The wave of blue clapped through the cavern and struck the dark user, forcing him back and into the ground.

The wild Pokémon suddenly stilled, coming to a shivering halt before they collapsed in exhausted heaps, the chains on their souls finally cut.

Sir Aaron turned to Mewtwo, "Get the others out of here!"

"Sir Aaron?" Ash called in confusion.

"Go! I'll handle this!"

Mewtwo set the work quickly, flying over to Ash, hooking the lad be the strap of his satchel and dragging him towards the others huddled in the back of the cave. Sir Aaron watched with a sense of relief Mewtwo warped them all away in a flash of white light. The relief was not long lasting, however.

"Well played brother," Anwir crooned, picking himself up from the ground a shroud of corrupt smog surrounding him, "Taking advantage of my weakest point."

"You shouldn't make it so obvious," Sir Aaron said.

"It would always be obvious to you. Top of the class, as you were," Anwir dusted off rubble on the shoulder of his coat.

"I may have been once, though it seems as if we've both outgrown those lessons."

"Yet only I have truly evolved. You're still the loyal lap dog that you've always been. Following every order instruction you were given. You're weak of mind Aaron."

"Obeying your masters are not weakness."

"The blind can see the truth easier than you."

"The truth? You wish to speak of the truth? The truth is that you betrayed our people and ways. The truth is that you turned to darkness rather than light…"

"Save me your heroic speech, it won't change things. We've chosen our sides, brother. Clearly, I'm on the one who will take control of this world," Anwir gestured to the heaps of fainted Pokémon that laid scattered throughout the cavern.

"How did you manage this carnage? None of our masters spoke of this dark power to us," Sir Aaron found curiosity taking his tongue.

"Oh, you like it?" Anwir chuckled, summoning a spinning sphere of shadows in his palm, "No master taught me this, in fact they tried to stop me. After all their morals and beliefs stopped them from ever uttering such practices. They blinded themselves to the potential one has once they have nothing holding them back. It took time, but eventually I learned to impose my will on others. Taking control."

"Anwir such tactics were forbidden for a reason."

"That was just to control us further. They never told us the truth, about anything."

"Arceus help you brother."

Anwir scoffed, a dark blade forming in his grasp, "He abandoned me long ago."

The dark user dashed forward with a battle cry ripping from his throat. The dark blade was raised high and swung down hard. A blast of excess energy thrashed throughout the cavern, and the black blade clashed with blue. Bringing the duel to a start.

Quickly the two users fell into practiced roles as the fight continued. Brother vs brother. Knight vs knight. It was a scene they had played in for all their lives. Only now this was no sparing match, the swords were not made of old oak wood, and the atmosphere was no longer of childish laughter. Only of bloodlust and anger.

Anwir was stronger than Sir Aaron remembered. The power that wafted off of the dark blade, making the knight's vision cut out and stomach twist, every time the swords struck one another. His younger brother was more aggressive with his arms, surer with his footsteps. He'd attack more than defend, like that of a predator with its meal in sight. Still, that didn't mean Sir Aaron wasn't unprepared. His own movements were fluid, blocking and parrying each assault with practiced ease.

Anwir's corrupted blade plunged forward. Sir Aaron barely managed to slip to the side, and out of the thrust's range. The knight shot out a hand, fingers clasping over Anwir's wrist, squeezing it. The joint was easily manipulated, the blackened sword dissipating at the unexpected touch. Sir Aaron yanked his brother to the side, before letting go and dropping to the ground himself, throwing out a leg and tripping the dark user.

The younger brother only managed to roll on to his back, when Sir Aaron pressed a boot into Anwir's chest and held a glowing blue blade to his throat. The dark user snarled, breathing harshly against the pressure pinning him down.

"Why do you hesitate? Do it. End this. Kill me," Anwir chuckled smirking, "Unless you can't."

"Yield," Sir Aaron swallowed.

"I'm afraid I can't."

In one drastic and unexpected, Anwir raised a hand and unleashed a power wave of darkness. It threw Sir Aaron back, the knight tumbling into the ground with cloud of dust and heavy groan. He tasted blood in this mouth and his teeth ached, but there was little time to dwell on it. A heavy rumble sent a shiver up his spine. Sir Aaron looked up and to his horror, the knight bore witness to the ceiling above cracking like thin glass as another dark wave was blasted at it.

"Are you mad?!" Sir Aaron screamed over the cavern destabilizing, "You'll kill us both!"

"Perhaps you shall perish brother, but I am beyond such trival worries," Anwir said fading into the shadows and dust storms that were quickly consuming the cave.

Sir Aaron for a moment searched for his younger brother amongst the chaos, but soon his lungs were flooded with freshly loose soil, and his own survival became more important. He was blinded by the impending cave-in. Dust in his eyes and rubble bouncing off of his body, no doubt forming fresh bruises. The knight continued to stumble near blind through the chaos, until a strong grip seized his shoulder, and he was pulled out of the collapse in a flash of white light.
