Sibling Rivalry.

Serenity ran up the long hallway, the sword propped on her shoulder. She had been running down the hallway for quite some time now, yet she had not slowed down. The hallway was the same as the others, it would twist and turn, doors on either side leading to labs or other areas, and it was slightly sloping, leading to one major room at the top. Serenity kept running, the only thoughts were of reaching Chaos, and rescuing her family.

The hallway continued on, as did Serenity's thoughts, 'Stitch will probably be angry when he awakens...yet he can't get involved! Too many innocents have already been involved in this, too many have fallen, I can't risk losing another friend. I hope Komalla's okay, I don't want the same thing to happen to him that happened to...'

Serenity's thoughts trailed off as she thought of her old friend. She shook her head, clearing her thoughts, and ran on, determined to finally end this...

Serenity rounded another corner, and stood facing a door. She stared at it, knowing what lies beyond its steel skeleton. Serenity stood in the hallway, watching the door, for a good five minutes. She took a deep breath, steeling herself for whatever was beyond the door, and reaching forward, pressed the red button. The door slid open, revealing a large room...

White marble covered the floor, the floor of a large rectangular room. Serenity gazed at it, there were many other floors, it appeared that there were four other stories above her. The room was long, and along the edges, ran pillars, it was very similar to the room that her and Stitch had battled Hades. Yet, at the very end of the room, beneath what appeared to be a throne, was a sight that made Serenity's stomach feel queasy...

Along the back wall, covering the entire wall, were stasis tubes. There were hundreds of them, all of them in rows, and columns, all stacked up on the wall. And within the stasis tubes, were the experiments. Serenity stared in horror, for nearly every single experiment was here, captured in a stasis tube. She saw 1-4-4, 2-6-8, and many others she knew of, and near the very end of the columns, there were 6-2-5 and 6-2-4. Serenity looked closely at the tubes, examining the experiments closely, and her worst fears were realized...

"Impressive, eh little one? I've worked hard on my collection, years of tracking them down, and capturing them, one by one, and storing them here," said the voice that reeked of pain.

Serenity looked to where the voice emitted, and watched as Chaos strolled out from behind one of the far pillars. He walked out, dressed in a black trench coat, with a red shirt beneath, with black pants and boots to match. Chaos walked out, and walked to the end of the hall, and sat on a large throne positioned beneath the wall of experiments. He smiled, and said, "Tell me sister, do you not find it impressive?"

Serenity walked forward, to the throne, and said, "I find it repulsive, that you would betray your own kind."

Chaos smiled, and glanced around the room. He scanned every part of the hall, scanning the floors above, and smiling, turned back to Serenity, and said, "My own kind? You think those lesser beings above us are our species? My sister, we are GODS compared to them, GODS! They should bow before us, harken to our every whim, throw themselves at our feet and beg for our favor, we are in no way related to those worms..."

Serenity stopped, a short distance away from the throne, once again she noticed Chaos scanning the room, looking for something. Serenity watched as his gaze returned to her, and she said, "They are not below us Chaos, but you have lowered yourself below them. Now, where is my family?"

Chaos grinned, and pointed to the opposite side of the room, and upwards. Serenity turned, and saw what appeared to be a monitoring room. It was a square room, with glass shielding it from the rest of the room. Within it, was the Pelekai family, and the aliens. All bound to their chairs, all gagged, none blind folded. Serenity made sure Komalla was okay, then she saw Lilo, and she made sure everyone was accounted for. Serenity nodded, and turned to Chaos, and she once again saw the experiments behind him.

"Why brother? Why do this to them?"

Chaos peered behind him, to the experiments, and chuckled, "What? I'm merely making them into a better being, giving them a better existence. They will serve me now, as masters of the darkness, masters of battle...Grims..."

All of the experiments, had a growth on them. It appeared to be a grey goo, slowly stretching across their bodies. Serenity understood what it was, it was the Black Virus, slowly turning them into the warriors of darkness, the Grims. She saw that some of the experiments, such as Sparky and Clip, were not yet entirely covered. Yet she saw that others, others that had been captured first, were almost completely, if not completely, transformed. Serenity shuddered, it was such a horrid existence...

Chaos turned back to her, "You know, the first one I caught, was experiment 3-4-5, the one everybody loves, a clown of experiments. He was on Mutos Five, in the alien circus. I so enjoyed listening to him scream as he went through the tortures, mmm, those screams were so...delicious..."

Chaos chuckled, and once again scanned the room. A worried look appeared on his face. He began scanning the room, checking every corner, examining every room. He stood, and looked about, Serenity watched him, a puzzled look on her face.

Chaos looked to her, "Where is he?"

Serenity didn't answer, the confused look on her face conveyed her thoughts. Chaos began to grow angry, "Experiment 6-2-6! Where is he?"

'Stitch?' Serenity thought, 'Why is he so worried about where Stitch is?'

Serenity glared at her brother, and answered sternly, "He won't be joining us."

Chaos was silent, his eyes were wide, and his teeth were clenched together. Serenity noticed that he was foaming slightly at the mouth. Chaos walked forwards a little ways, and shouted, "WHERE IS HE!"

Serenity backed up a little, and said, "Like I said, he won't be joining us, I protected him from your harm."

Chaos threw up his hands, and bellowed in anger. He stormed about, cursing like mad. He turned to Serenity, his eyes seemed to grow brighter, "DO YOU KNOW WHAT YOU'VE DONE? YEARS OF WORK, UNRAVELED! YEARS OF WAITING, RUINED! HE IS THE KEY AND YOU FAILED TO BRING HIM HERE? ALL MY SEARCHING, ALL MY HARD WORK, AND THE ONE, THE ONE, IS NOT HERE!"

Serenity watched as Chaos stormed about. Then Chaos turned to her, "It makes no matter! Soon, he will arrive, I know he will. Whatever you have done, he will come, and then, it will finally end...all of it...will not be for naught..."

Chaos turned to Serenity, and extended his blades of darkness. He smiled evilly, and said, "Come, for angering me, I will kill you, much like I did that bitch you lived with on earth..."

Serenity heard the words, and brought up the Omega Sword, anger filled her being, she would have justice for Mertle's death. Chaos laughed, "So you brought the Omega Sword, it makes no matter, that toy will not aid you in this battle. I will tell you one thing though, your little friend, she was a beautiful screamer..."

Serenity raised the sword, "SHUT UP! COME! LET US END THIS!"

Chaos raised his blades, "Fine by me..."

Brother and Sister, born in the light, one twisted by the darkness. Their battle has raged for nearly three years now, and finally it has come to this. Poised against each other, the closest of relatives, friends in the beginning, enemies in the end. Son of Darkness and Daughter of Light, the antithesis of each other. Chaos stared down Serenity, and Serenity held the Omega Sword tightly. Chaos grinned, and charged, Serenity ripped back the pommel on the sword. Chaos saw this and leapt high in the air, Serenity aimed carefully, and swung the sword in an upward angle, sending a blast of green light towards Chaos. Chaos twisted in air, dodging the blow, and landed behind Serenity.

Serenity turned, but was not swift enough, and Chaos knocked the sword from her hands, and it clattered away. Serenity quickly extended her blades, and Chaos began the attack. He was swift in his blade movements, but Serenity managed to parry and block them. Serenity parried his attack well, and went on the offensive. Chaos moved with surprising speed, and managed to block her every attack.

Serenity began to attack with one hand, and in her other, formed a ball of energy. Chaos saw this and leapt away. Aiming carefully, Serenity threw the ball where she judged he would land. Chaos noticed, and spread the darkness around him, and the ball collided with the darkness shield, and a large explosion rattled the area. Serenity wasted no time, she began to charge the area where Chaos had stood. All of a sudden, a torrent of dark spears erupted from the smoke where the explosion had appeared. Acting quickly, Serenity leapt from side to side, dodging the attacks as they fell around her. The smoke cleared, and Chaos was left wide open. Serenity leapt in, and sent a punishing kick to Chaos's nose.

Chaos recoiled from the blow, dark crimson blood sprang from his nose. Serenity was on the ground again, and charged forward to attack once more, yet she failed to see the dark tentacle coil around her feet. Serenity was surprised when she was lifted from the ground, and the tentacle slammed her into the ground, it lifted her again, and whirled her around, slamming her into a pillar. The pillar gave way, and debris fell atop Serenity. Chaos pulled his darkness in, and waited, his arms hanging loosely at his sides.

The debris began to rumble, and Serenity burst from it, a glowing orb in her hand. She reared back and threw the orb with all her might. Chaos wasn't fast enough to raise a defensive barrier, and it slammed into him. The explosion rattled him, and he flew backwards, with Serenity right behind him. Chaos smashed into the wall, and Serenity was right on top of him, and she sent a flurry of punishing blows to Chaos, smashing into his torso, face, anything Serenity could see. Serenity reared back, and sent a punch aimed at Chaos's face, and felt her arm being held. Serenity saw that Chaos had her by the arm, his eyes gleaming dangerously. Chaos whipped her around, and slammed her into the wall. Chaos then lifted her, and sent a cruel blow to her stomach, and Serenity went flying across the room, landing near the middle of the floor.

Serenity was immediately on her feet, she felt a pain on her head, and she reached up, and carefully touched the spot. Pain shot through her, and she pulled back her hand to see it was wet with blood, probably from a gash in her head. Serenity looked up, to see Chaos flying towards her. Serenity set herself in a defensive position, getting ready. Chaos and Serenity met, and once again they were locked in a parrying battle.

Chaos moved quickly, ducking in and out, trying to destroy Serenity's guard. Serenity stood solid as a rock against his attacks, and parried them all expertly. It seemed they were dancing, a mystic dance of danger, as blades fell, and clashed together, emitting sparks as the blades of light and darkness met. Time after time the blades met, sending sparks into the air.

Chaos watched Serenity carefully, making note of her movements. Chaos suddenly dipped low, and swung his leg around. Serenity wasn't ready for the sweep, and she was knocked off her feet. She fell to the ground, and Chaos leapt high in the air, and brought his feet crashing into Serenity's chest. Serenity felt the air escape her, and for a second she couldn't breath. Chaos reached down, and picked up Serenity, and he held her in front of him, and grinning, rocked her small frame with a punishing blow to the stomach. Serenity was having trouble breathing, she was growing frantic, she had to escape from his grip.

Chaos reared back to send another blow to Serenity, and Serenity reached forward and placed her hand on Chaos's forehead. Chaos noticed a light coming from Serenity's palm, and a beam of light smashed into his face. Chaos went flying once more, dropping Serenity. Serenity hit the ground, sputtering for air. She coughed, and inhaled deep breaths, trying to get some air. She heard a sound, and looked to see Chaos, already recovered from the blast, standing. Serenity still had problems breathing, and tried to stand, but she fell to her knees. Chaos noticed her weakness and charged.

Serenity saw him coming and began to panic. She still could not get sufficient air. Chaos drew closer and closer, charging her. Serenity raised her arms, and began to draw in energy, she could not afford to allow him to attack. Chaos noticed this, and sent two tentacles for her. Serenity drew in her energy, and was about to fire, when one of the tentacles knocked her hands aside, and the blasts slammed into the far wall. The other tentacle reached her, and grabbed her around the middle, and in an almost strangling grip, lifted Serenity into the air, and brought her crashing down. Serenity realized she was in trouble, she was having extreme trouble breathing, and the fact that she was being slammed into the floor didn't help either.

Chaos watched on, a cruel grin on his face as he slammed Serenity deeper and deeper into the ground, a large crater appearing from the repeated attack. Serenity began to grow desperate, and she extended her blades, and finally finding the strength, she cut the tentacle off of her. The dead end of the tentacle dropped her, and she fell to the ground, and cut the rest of the tentacle from her middle. Chaos brought in the rest of the darkness, and charged. Serenity looked up, to see Chaos's boot slam into her. Serenity flew back, and slammed into the throne, knocking it over.

Chaos stood still, smiling, and said, "You know sister, you were never a match for me, and with the power of the virus, I am truly unstoppable."

Serenity stood, and bent over, her hands on her knees. Pink blood ran from the gash in her head, her white fur matted from the blood. She tried catching her breath, trying to think. 'He's...so much stronger...than before...'

Chaos began to walk towards her, slowly, tauntingly speaking to her, "You are weak, you could never understand what true power is, you could never comprehend the power I contain."

Serenity brought herself up, finally catching her breath, she said, still gasping for breath, "True power is not measured in strength alone Chaos, something you never understood."

Chaos stopped, and asked, "You do seem different sister, I noticed something new about you, then indulge me. What is true power?"

Serenity brought herself to full height, "I gain power from those who love me, I gained confidence from them, and with confidence, comes strength..."

Chaos erupted with laughter, "Hahaha! Pah! You think love gives you strength? You think having feelings can save you from me? You are terribly mistaken in your opinions of power dear sister, a mistake that is about to cost you your life..."

Chaos extended his blades, and grinned. Serenity stood, and extended her own blades. She faced Chaos, and spoke with determination, "If it takes my entire being, I will give you atonement brother!"

Chaos and Serenity charged one another, and the battle resumed as the experiments and Pelekai family, watched on...

Stitch awoke. He slowly sat up, a throbbing feeling in his head. He groaned, and rubbed his head, which now felt several sizes too small. Stitch looked around, and recalled what had happened.

"Serenity! Dammit, why'd you knock me out?"

Stitch thought about it for a moment, then realized, "To protect me...but wait...she must be..."

Stitch noticed the open door in front of him. He felt for the Omega Sword, and found it was missing. He swore with anger, and stood, his legs felt like rubber, and he staggered for a moment before regaining his balance. Stitch looked at the door, and said, "I hope she's okay..."

Stitch ran into the door, and charged to the battle ground...
