Disclaimer: I do not own Pokemon if I did Ash would age and win a proper league

A/N: Here is a filler chapter, this is completely original and didn't happen in the anime, however as I thought what I could write, it just all came together, I hope you enjoy the chapter.

Unknown Location

Domino eyes fluttered open, she had a splitting headache, she went to use her hands to hold her head when she realized they were restrained by Dark black strands which were tied to the bed she was now laying on. Domino went to scream, but couldn't due to the duck tape across her mouth. She tried to wriggle on the bed to try to loosen her bonds, however, it was no use. Her legs had also been retrained and were now spread on the bed. Domino looked to the door which suddenly opened to reveal Eberus stood in the doorway.

"Comfy are we my pet" Eberus stalked towards his helpless victim.

He might still be under the control of Team Rocket, but only just. Unknown to Giovanni the control had been wearing off gradually thanks to his aura. He now had a certain amount of free will back, he still couldn't attack Giovanni, but indirectly was a different matter entirely. Eberus knew Domino was very loyal to Giovanni and that he trusted her more than he trusted him at the minute. This was the key to his plan. He would use Domino to get rid of Giovanni and then he would take over as leader of Team Rocket. He moved his hand towards Domino cheeks and stroked them with the back of his hand.

"Don't worry my pet, this will be all over soon, after the first dose you will be begging for more." Eberus traced his hands over Domino body, starting from her neck, and working over her breast and down to her thighs. "Such beauty, you will make a fine slave.

Eberus then left the bedside before closing the door. He then turned and started to remove his clothing, he could see the terrified look on Domino face, as it finally dawned on her exactly what he was about to do.

Meanwhile On way to Lavender Town

Ash and the girls had left Cerulean City and now they were on their way towards the third battle frontier facility known as the Battle Pike. The facility was located just outside Lavender Town, and instead of flying, they had decided to take the scenic route. This allowed Ash to show the girl the secret village where he met Bulbasaur. Venusaur had been thrilled to see all his old friends and Melanie could believe that he had evolved into his final form. After a light lunch and a little time catching up, Ash and the girls left Melanie and the other injured Pokemon that she was helping to recover.

They walked past the small rock where Ash had rescued Charmander and the Pokemon center where Ash had first used his aura powers, and where he had met Sabrina for the first time. Cynthia was interested in that story and so both Ash and Sabrina gave their accounts of it. They passed the power plant where Ash had first encountered Zapdos who had been trying to escape from Team Rocket who had been posing as employees of the Powerplant to try trick people. Ash wasn't sure what would have happened had he not been able to communicate with Zapdos, team Rocket did such a good job of disguising themselves, that had he not known then he would assume they were just employees.

Eventually, they finally arrived in Lavender Town. The huge tower where Ash and Sabrina had encountered Gengar and the ghostly trio loomed above the small town. The streets were busy with people shopping, and many of the stores that had been closed before were now open. The three teens made their way towards the Pokemon Centre they would stay overnight here before tackling the battle Pike tomorrow. His Gengar had also wanted to pay a visit to the tower to catch up with his old buddies, he also wanted to show them that Litwick was now fully evolved.

Lavender Tower

Ash, Sabrina, and Cynthia looked up at the looming structure in front of them, for some odd reason it was all boarded up, and warning signs were posted on the door, telling people not to enter. The ball in Ash coat began to shake and suddenly Gengar appeared from his Poke ball. The Ghost/poison duel type examined the noticed and then turned to Ash.

"I'm going to check it out, boss." Gengar ghosted through the door leaving Ash and the girls to wait, just then an old man came walking along.

"Hey, you kids shouldn't be anywhere near there, get back before you get hit." Just as the man had spoken something was thrown from the top window and would have hit Ash had he not stepped back. "Kids these days, take no notice of signs."

Ash was wondering what was going on. "Excuse me, Sir, do you know why the tower is closed, and how long it has been closed for?"

The old man examined the three teens and shook his head. "Tourists I might have known, listen, kid, that tower has been in locked down for a month now. The caretaker who looked after it was attacked by a group of ghost Pokemon. Anyone who goes near that tower now gets stuff thrown at them from the windows. If I was you I would stay well clear." After the old man had given the warning, he walked off leaving Ash and the girls to ponder what they had been told. As the old man left Gengar came shooting out of the doors.

"Big trouble boss, my old friends are in real trouble. A Dusknoir and a group of Duskull have moved into the tower and they are causing trouble, all the Gastlys, Haunters and Gengar are constantly fighting them. My old boss got hurt real bad and now Dusknoir has taken over."

Ash was surprised. "Do you know where they have come from Gengar, as last time we were here I didn't think there were any other ghost Pokemon in the tower except you three."

Gengar nodded. "Old boss tells me they moved in a month ago, the building that they had been living in was knocked down, and so they decided to make the tower their home. My old boss was prepared to let them share, but the Dusknoir decided to try and overthrow him, and take over the entire tower, now all the other ghost Pokemon are scared and are hiding.

Ash frowned. "That's not fair, your friends were there first, come on let go and meet this Dusknoir, Sabrina, Cynthia are you coming?"

Sabrina and Cynthia looked at each other and then back to Ash. It was Sabrina who answered. "Actually Ash we will let you sort this out, Cynthia and I saw some really cool shops that we want to explore, here take Chandalure Poke ball, I'm sure she would love to see the one who took care of her."

Ash took the ball and kissed both girls before the went their separate ways, Ash towards the tower and the girls towards the shopping center. As Ash approached the door, more objects were thrown his way. Ash's eyes glowed blue and his aura surrounded him. The Object bounced harmlessly off him. He focused on the padlock and used his aura to break the then pulled open the door and slipped inside along with Gengar.

Ash found himself face to face with the large spiral staircase that he had climbed on his first visit here, however soon as his foot stepped onto the first step he was pushed back by an invisible gust of wind.

"Begone human! You're not welcome here, this is your final warning, leave now or face the consequences."

Ash ignored the voice and again placed a foot on the bottom step and waited. Nothing happened, so he continued to climb the steps, however as they got higher he noticed the top half of the staircase had been blocked off by clatter.

"This way boss, old boss is in here." Ash followed Gengar down the corridor and into one of the rooms, as he entered the door behind him slammed shut, and the ghost Pokemon slowly began to appear, however, gone was the usual smiles and fun expression, now their faces were all showing fear. In the middle of the room was a large Gengar surrounded by the other ghost Pokemon, as Ash approached the ghost Pokemon began to block his path.

"It is fine, let him come through, he is a friend" After hearing their boss give the all clear they parted allowing Ash to approach the large Gengar with his own Gengar at his side.

"I bought my trainers just like you asked old boss, he can help you, he is really strong."

The large Gengar grinned, but Ash could see it wasn't his usual grin. "Thank you young one, I see you have grown into a Powerful Gengar, and as for you young trainer welcome, I see you too have grown, not just in size but power too. Tell me how is young Litwick?"

Ash removed the ball Sabrina had given him. "How about you ask her yourself. " Ash threw the ball up and Chandalure appeared floating near Ash. "She no longer a Litwick now, but she fully evolved. Chandalure, you remember this Gengar, don't you? He the one who looked after you when you were a little"

The ghost/fire duel type examined the large Gengar and floated over towards it. "Thank you for looking after me when I was younger, if it wasn't for you, then I might not have met my mistress."

The large Gengar grinned. "It is good to see you again, and I am pleased that you have found a powerful trainer. Forgive my state at the minute but I am weak from battling Dusknoir, he tried to pick on two of our younger Gastlys"

Ash frowned. "Is he it really that strong then? I've faced a Dusknoir before but the one I faced was quite weak. From your injuries, it looks like it did a real number on you. I could help you if you let me. I have some full restore here, this will heal you up."

The large Gengar nodded. "Thank you, trainer, I would appreciate the aid, as you can imagine I can't exactly visit a Pokemon Centre." It winced as Ash sprayed its wounds, which after a few seconds began to vanish. The large Gengar floated up and flexed it arms. "My that feels a lot better, thank you."

Ash placed the full restore back into his rucksack. "Your welcome, Gengar tells me that you offered to share the tower with this Dusknoir and his Duskulls, as they have been driven out of their home."

The large Gengar nodded. "Yes I said they were welcome to stay, but I did tell them that I was in charge and that they needed to remember they were guest here. The Dusknoir didn't take that well and decided to challenge me, for dominance. In the end, he won, but those who were with me, refused to listen to him, and so an all-out war began. It's been going on for a month now, both sides have suffered. I just want the fighting to stop, but Dusknoir won't listen. He and his Duskulls have even started to throw stuff out of the tower window onto the human town below."

Ash leaned against the wall with his arms crossed. "Yes I heard, the caretaker who looks after the tower was hit on the head by an object and the tower was sealed off. Dusknoir tried to kick me out of the Tower, but Ignored his warnings."

The large Gengar grinned. "You are very brave, I know this might be asking a lot, after all, you just healed me, but I was wondering if you could take care of Dusknoir for me. Although I am healed now, I am getting on in years, and I don't battle the way I use too. I can't bear to see the youngsters scared like they are."

Ash adjusted his cap. "Count me in, If it is one thing I can't stand its a bully be it human or Pokemon. Where is he now?"

Gengar was pleased the young trainers was prepared to help settle their dispute. "He stays in the top room of the tower, however getting to him won't be easy, not only Duskull protect him now, but a few have evolved into Dusclops. I am sure several of my Haunter will help you break through their lines. As if Gengar was expecting a reaction, several Haunters appeared with a determined look on their faces.

Ash looked towards the Haunters. "Okay if we are going to do this then I need you to listen to me, and do everything I tell you too."

All the Haunters nodded in understanding and followed Ash out of the room and into the corridor. As they made their way towards the stairs, three Duskulls appeared and all launched shadow balls towards them.

"All of you counter with your shadow balls, Gengar use Dark Pulse!" All the Haunters used Shadow ball, which clashed with the incoming attacks from the Duskulls, this left Gengar with a window of opportunity and he used Dark pulse which struck all three Duskulls and caused them to retreat. "So far so good. Gengar, use Focus blast on that rubbish!"

Gengar formed an orb of power between its hands before lopping the sphere at the pile of clatter which exploded opening a path up the stairs. Ash, Gengar and the Haunter raced up the stairs until the reached the top. On stepping into the corridor they were stopped by three Duskulls and two Dusclops, all fired off willo wisps.

The orbs of flames were racing down the corridor. Ash's eyes glowed blue and once again he was surrounded by his aura, which on impact with Willo wisp caused them to disperse. "Enough I want to challenge Dusknoir, stop being a coward and sending your lackeys, show yourself."

"Bold for a human aren't you! Very well you wish to see here I am!" Dusknoir suddenly shimmered in front of Ash this caused all the Dusclops and Duskulls to retreat behind their boss. "Well Human, I am here, now what?"

Ash narrowed his eyes. "I am giving you an opportunity. You face my Gengar one on one, If we win you give up leadership, if you win then I will leave this tower, and not interfere any further, I give you my word as an Aura Guardian, however, as a Pokemon, you also have to swear.

Dusknoir one eyes rotated as it thought about the proposition. "Why are you concerned human what is going on, this is between me and Gengar, why are you interfering? This is between us Pokemon, nothing to do with you humans."

Ash frowned. "You say it has nothing to do with us humans, yet your fight is causing casualties. The caretaker who took care of this tower was hurt, not to mention your stopping tourists from visiting this tower. This tower is a huge attraction for this city, there was never a problem before you came here. So it does concern us human, not to mention this Gengar use to live here and was looked after by the large Gengar you have hurt. So as a trainer and an Aura Guardian it's my duty to step in."

"Very well Human I swear as a Pokemon that if you win then I will give up and let Gengar lead, I also promise to become your Pokemon, but you won't beat me, so that won't be happening, now prepare yourself human."

Dusknoir wasted no time in attack as a large spectral fist appeared and smashed into Gengar taking it by surprise.

Ash narrowed his eyes. "Okay, you want to play that game. "Gengar use Dark Pulse now!" Gengar formed an orb of dark energy between its hands, it then dispersed a large back wave of dark energy that hit Dusknoir and caused it to flinch. "Now Gengar use Hypnosis!" Gengar eyes glowed as it sent out hypnotic wave towards Dusknoir, who suddenly vanished and was replaced with a dummy. It had used Substitute."

Dusknoir suddenly reappeared and threw another Shadow punch towards Gengar who took the attack head on and smashed into one of the nearby walls.

Ash looked towards Gengar he was little dazed but nothing more. "Gengar use Dark Pulse! And then Shadow ball!" Gengar launched the two attacks one after another. The dark Pulse broke the substitute and the shadow ball was dispersed by a willo wisp by Dusknoir.

Gengar, dodge and then use Hypnosis!" Gengar dodged the willo wisp and then launched another hypnosis which again caused Dusknoir to use Substitute and again a Shadow fist appeared and was about to hit Gengar, however, Ash countered. "Gengar use Shadow ball!" The Shadow ball smashed into the fist and then shattered it, and hit the substitute breaking it, this caused Dusknoir to appear once more.

Ash knew he had caused enough damage that he was certain Dusknoir wouldn't be able to use Substitute again. "Gengar Hypnosis one more time!" Gengar for the third time used Hypnosis this time it hit and caused Dusknoir to fall asleep.

Ash removed a ball from his coat. "Go Poke ball!" The ball hit Dusknoir and then sucked it inside and fell to the floor, where it began to shake from side to side. Finally, it stopped shaking and the ding sounded meaning it was a successful capture. Ash walked over and picked up the ball, he then turned towards the Duskulls and Dusclops. "I have defeated your leader, as per the agreement you are now to listen to Gengar, any who don't want to stay here, then I suggest you leave now."

The Duskulls and Dusclops didn't move, however, when they saw the large Gengar appear with Chandalure, they retreated.

"I am certain they will be no more trouble, you have defeated their leader, thank you, trainer, maybe now we can all start to live in peace with one another."

Ash nodded, not only had he helped end a dispute between ghost Pokemon, but he now had a new Pokemon to train. By Dusknoir's attitude, it was clear he would have to put a lot of effort into training it and making it understand its place.
