Note: The Black WarGreymon in this chapter is NOT the same Black WarGreymon in Digimon 02. He did not get reconfigured. This is a new Black WarGreymon, but I haven't thought of how he existed yet. I'll think of an explaination in later chapters.

Also, in this chapter Chaos WarGreymon is revealed to have a new ability he had never used before.

VENGEANCE

- Chapter 13 - Chaos VS Black -

by

Alforce Zero

It was the first time Chaos WarGreymon had ever seen another WarGreymon other than himself. He was reminded of what Kuzuhamon had said to him earlier, during their encounter at the Ice Lake.

"A WarGreymon? Well this is interesting. I haven't seen a WarGreymon before, but I've always thought WarGreymons are good digimons, serving the side of good. But you? You serve the forces of evil."

'So even Kuzuhamon herself never ventured this far,' Chaos WarGreymon thought to himself while noting the differences between himself and his opponent. The only difference present between the two of them were the colors of their armor. The armor worn by his opponent was all completely in black, save for the yellow tubes which were intertwined over his greyish chestplate. Whereas, Chaos WarGreymon's shoulder pad armor, the shield, and the knee caps were silver, and his chestplate was gold in color while the other parts of his armor was in the darkest shade of grey.

Black WarGreymon had never seen Chaos WarGreymon before as well, but he remained calm.

"What purpose have you, Chaos WarGreymon, for venturing until the deepest part of the Kulon Mines?" he asked.

"I'm here under my master's order to retrieve a crystal," Chaos WarGreymon replied curtly.

"I'm afraid this is as far as you can go, because we will do everything in our power to stop you."

"Yeah, I figured that. That's what they said," Chaos WarGreymon said. "And I've beaten them all."

Black WarGreymon didn't reply to this. Instead, he stomped his foot on the metallic grounds and instantly, the formerly dark surroundings were lit up with strange purple light, which seemed to be radiating from the cave walls. Chaos WarGreymon realized that he was inside some kind of a battle ring, constructed similar to that of the Ice Lake and the Underground Volcano regions.

Without warning, more than ten Bakemons and five Phantomon floated down out of nowhere. They just seemed to appear when the lights came out. The ghostly digimons hovered close around Chaos WarGreymon, all seemed to be ready for battle. The Phantomons readied their scythes, while the Bakemons just floated around the dragon digimon and emitted strange eerie sounds as they did that.

"Is this the best you can do?" Chaos WarGreymon asked, supressing a tone of disbelief. "Champions and Ultimates?"

"Not so," a mechanical voice replied. The voice came out from the far left end from where all of them were standing. Chaos WarGreymon spun left, and saw a black android figure walking towards him cooly. He looked like an Andromon - a completed version of Andromon without his flesh exposed to air. The black-armored digimon was HiAndromon, a Mega form of Andromon. He walked towards Black WarGreymon, and stood beside him soon after. The two Mega digimons eyed Chaos WarGreymon warily.

"This may be the toughest obstacle I have to face in this cave," Chaos WarGreymon said. "Still, I've faced worst before."

"We shall see, Chaos WarGreymon," Black WarGreymon said irritably. "Bakemons! Phantomons! Attack the intruder!"

The Bakemons all approached Chaos WarGreymon with their usual eerie style. Massive blue hands shot out from the sleeves without warning, punching the dragon digimon mightily. The combined forces of five Bakemons however were still inferior compared to Chaos WarGreymon's sheer strength. He didn't even make an effort to evade the attacks the Bakemons had inflicted upon him.

Chaos WarGreymon raised himself up into the air, and turned into a raging silver tornado.

"Great Tornado!!" he bellowed, and rammed through all the Bakemons. The poor ghost digimons instantly combusted into millions of data particles. Next, he set his eyes on the Phantomons, who cowered slightly but still were determined to fight. However, Chaos WarGreymon didn't want to waste time fighting them, and launched himself as a tornado again. The phantom digimons tried to evade the attack, but they weren't quick enough and thus suffered the same fate as their ghost friends.

"And now for a quick meal," Chaos WarGreymon muttered and spread his arms wide. His body emitted a faint silver glow, and instantly the data particles of the deceased Phantomons coalesced around him and were absorbed into his body. Instantly, several cuts and scorch marks which were present on his body were healed slightly.

Black WarGreymon and HiAndromon were shocked. Neither of them had anticipated such action demonstrated by Chaos WarGreymon.

"It can't be! He healed himself after absorbing the data particles of the Phantomons!" HiAndromon exclaimed.

Chaos WarGreymon growled slightly before sneering towards his opponents. The ability to absorb data particles of deleted digimons was a trait unique to only the Chaos Generals and Chaos Specter's pet digimon BlackGatomon, bestowed upon them by Chaos Specter himself. As far as he had known, it was an ability of digimons from another Digital World dimension which Chaos WarGreymon had never ventured.

"Stop right now, Chaos WarGreymon!" Black WarGreymon commanded.

Chaos WarGreymon looked at both Mega digimons with mild interest.

"I am healed to nearly full strength," he said. "Neither of you can defeat me now! If you don't want to suffer the same fate as those Phantomons, make way now and I'll leave you in peace. Otherwise ---"

"Your threats don't scare us!" Black WarGreymon bellowed angrily. "We'd taken an oath to protect this region, and we'll do it even if it cost us our lives!"

"Looks like you're not as smart as I thought. Really, is Kuzuhamon the only digimon around here who puts a high value in her and her friends' lives? They gave way instantly after I had proven myself to be stronger than any of them. Those Meramon fools however were foolish to engage me into a battle, and as a result... I'd deleted them all!!"

Hearing this, both Mega digimons were shocked.

"You evil being! We will not let you win, Chaos WarGreymon!" HiAndromon said with determination.

"Looks like the two of you are just the same with those stupid Meramons. Thinking using their legs instead of their heads," Chaos WarGreymon said with a sneer. "I shall enjoy devouring your data particles, which will make me even more stronger than before! Ha Ha Ha Ha Ha !!"

"I'm willing to bet that you're all talk!" Black WarGreymon spat.

"Oh really? Why don't you try me?"

"You'll soon wish you regret saying that! Terra Destroyer!!" Black WarGreymon hurled the dark versions of the Terra Force towards Chaos WarGreymon. The sheer force of the attack hurled Chaos WarGreymon towards the walls of the caves, where he was sent crashing. This shocked Chaos WarGreymon, he never knew that Black WarGreymon was that strong. He regained his composure and powered himself up immediately.

"Well this is certainly going to be very interesting," he muttered. "Terra Force!!"

"Terra Destroyer!!"

The attacks collided together and caused a huge explosion, sending both Chaos and Black WarGreymons flying away in opposite direction. Both digimons were engulfed with thick smokes which came from the collision of the attacks, and it would took a while before the smokes subsided. Without their visions, both WarGreymons became more alert of any sudden sounds and movements, fearing that any one of them would take the chance to strike at the other unexpectantly.

HiAndromon, who was watching the battle saw his chance to help his comrade getting rid of the intruder.

"Now's my chance. Copy Paste!" he said, and instantly another HiAndromon figure stepped out from his body. Two HiAndromons stood side by side now instead of one. Both digimons had the same attack skills, however their powers were reduced that each HiAndromon only possessed around 60% of their original power compared when both of them became one. In times like this, HiAndromon felt that it was crucial for him to have more help around to defeat Chaos WarGreymon.

The two HiAndromons stepped closer to the smokes. They wanted to attack Chaos WarGreymon unexpectantly. However since both WarGreymons had the same silhoutte visible from within the smokes, it was nearly impossible for any HiAndromon to differentiate one from the other. Now wanting to hurt Black WarGreymon unintentionally, both HiAndromons waited for the perfect moment to strike.

Suddenly loud roars were heard and from the smokes, two tornado shot out from it. One was black and the other one silver. The two tornadoes nearly collided with each other, but both were able to avoid that from happening.

Chaos WarGreymon was just about to settle down when suddenly...

"Atomic Ray!!" He was blasted from behind, no doubt from HiAndromon. But even before he could turn behind to see his attacker, another attack was shot at point blanc when he turned his head away slightly. This made Chaos WarGreymon slightly flustered, how could HiAndromon be so fast? He then caught on HiAndromon, and nearly choked out in disbelief as he saw another HiAndromon hovering close near the other one.

"What's the matter?" one of them spoke.

"Can't get enough of both of us?" the other one said.

"What trick is this?" Chaos WarGreymon wondered out loud.

"With my Copy Paste attack, I can duplicate an exact replica of myself," the first HiAndromon answered, leaving out the part about them losing a certain percentage of power while in their duo mode.

"And now take this! Atomic Ray!!" the second HiAndromon bellowed.

Chaos WarGreymon evaded the attack by flying upwards, where he was blocked by Black WarGreymon.

"Going somewhere?" he asked.

"Damn it!" Chaos WarGreymon said angrily. "Mega Claw!!" he slashed his claws towards Black WarGreymon, but the attack was blocked by Black WarGreymon's own claws.

"I show you how it's supposed to be done! Mega Claw!!" Black WarGreymon attacked his evil twin counterpart with the same attack, and hit Chaos WarGreymon's chest. Soon, both Mega digimons exchanged powerful blows towards each other so quickly that in one minute almost fifty blows were exchanged. Then, they powered up themselves and launched themselves as tornadoes towards each other. The battle between the WarGreymons continued for nearly an hour, when Chaos WarGreymon finally detected a weakness of Black WarGreymon.

"He's tiring!" Chaos WarGreymon said gleefully. "Say good-bye, Black WarGreymon!!" he bellowed and energized a massive fireball with both his arms raised upwards. "Terra ---"

"Not so fast! Atomic Ray!!"

"Atomic Ray!!"

The two HiAndromons had intercepted Chaos WarGreymon's attempts to finish off Black WarGreymon. Their attacks evaporated the fireball Chaos WarGreymon was about to launch. This made the dragon man digimon even angrier.

"Curse it! Great Tornado!!" he attacked the two HiAndromons, whose speed were decreased as well while they were separated into two entities. The HiAndromons fell into the grounds and merged back into one HiAndromon. He groaned slightly as he tried to stand up, but again he was rammed by Chaos WarGreymon, which managed to cause some serious damages on HiAndromon's armor.

"Mega Claw!!" Chaos WarGreymon cried as he was about to ram HiAndromon again. His claw pierced through HiAndromon's thick armor and HiAndromon let out a sickening howl before dissolving into million bits of data particles. Chaos WarGreymon growled triumphantly and was about to absorb the data particles when Black WarGreymon stopped him by launching a Terra Destroyer towards him, thus unabling Chaos WarGreymon to increase his strength.

"I'll make you pay for what you did to my friend, Chaos WarGreymon!" Black WarGreymon said solemnly, and focused his remaining powers towards his claws. He raised both claws upwards, and as a massive black fireball formed above his hands his body glowed with black aura as well. Black WarGreymon knew that his chance to defeat Chaos WarGreymon was very slim, but he refused to give up just yet. He willed every power that was left inside his body towards the glowing orb he'd formed, determined to deliver one last blow towards Chaos WarGreymon. Black WarGreymon thought about the Bakemons, the Phantomons and his comrade HiAndromon, all slaughtered by Chaos WarGreymon without mercy. He knew that what he was about to do was suicidal... a kamikaze attack.

"YAAAAARRGGHHHHH!!! TERRA DESTROYER!!"

He launched the final Terra Destroyer towards Chaos WarGreymon, and instantly felt that he was severely weakened. The massive attack collided with Chaos WarGreymon who was about to perform a counter-attack, and caused a massive explosion. Black WarGreymon then felt something strange was happening to him, and as he looked down he saw that his lower limbs were beginning to dissolve into data particles. Soon, his upper extremities and torso suffered the same fate, and he closed his eyes before every remaining parts of himself combusted.

The smoke from Black WarGreymon's kamikaze attack began to subside after a few minutes. A figure emerged from the smoke.

"Blast!" Chaos WarGreymon cussed, holding his torso. Black fluid escaped his claws, spilling itself onto the floors. A large part of his armor was broken, damaged and destroyed. Chaos WarGreymon was severely hurt, although thanks to the extra power boost from Chaos Specter he had managed to survive Black WarGreymon's final attack, which would be fatal if imposed to other digimons. He could no longer walk properly, his left leg was limped. He felt so weak that he could not even fly his way towards the doorway leading to the exit of the cave. Chaos WarGreymon didn't know where the exit leads to, but he hoped that it would lead him straight to the crystal which Chaos Specter had ordered for him to retrieve. He wasn't in any condition to fight anymore. In fact, even though he had survived the attack he was crippled for the rest of his lives. Chaos WarGreymon silently hoped that there would be a remedy for his condition, and slowly made his way towards the exit.

The exit took him towards a large metallic door which led to a chamber. Chaos WarGreymon was sure that behind the door was the place where he would be able to retrieve the crystal his master had so wanted. Focusing every bits of his depleting energy, he rammed the door and the door opened.

Chaos WarGreymon groaned slightly, and suddenly he glowed with silver lights. After ramming the door open he had absolutely small amount of energy left within him, and could no longer sustain his Mega level. Chaos WarGreymon then de-digivolved into an Agumon. He looked like a regular Agumon, but the orange color on him looked duller than any regular Agumon. Silver markings in a shape of two short thin lines were visible under Agumon's eyes and on his paws and foot. He had been a regular Agumon before, but after bestowed with the Chaos powers from Chaos Specter, he half-guessed that some of the effects had rubbed in every of his digivolutionary forms. (A/N: I'll refer him as Chaos Agumon from now on)

Chaos Agumon passed over the doorway and emerged into a giant and dim underground cavern. In the center, there was a tall stone pillar with a staircase leading to the very top where a glimmering purple crystal hovering over a podium. A beam of light made the crystal seen as if begging to be taken, and the crystal itself was shining with soft white-violet lights which lit the dark cavern. The pillar was surrounded by water where an uneven set of stepping-stones formed a bridge. Groaning, Chaos Agumon began to limp his way towards the pillar.

When he reached the bottom of the stone pillar, he saw that he had to take a flight of stony stairs in order to reach to the top. He climbed the stairs one step at a time, and estimated that there were almost fifty steps of stairs he had to climb before reaching the top. It was hard work, as he was crippled, severely weak, and could not fly all the way up. He was feeling hungry as well, but then he hastily bit his lip, imagining how Chaos Piedmon and Chaos Seadramon would react when he would return to the Velvet Claw in his Rookie form.

'Coming to think of it, how am I going to go back?' he thought to himself despairingly.

After almost an hour of climbing the stairs he finally reached the podium. There it was, the purple crystal which he was sent to retrieve. The crystal was hovering on its own, emitting strange violet-white lights all over the dark cave.

"You're sure are a lot of trouble to get to," Chaos Agumon said as he watched the crystal with fascination. "What could be so important with this crystal that master would want it so badly?"

Suddenly, a ghostly image appeared within the crystal and caught the attention of the Rookie digimon. It had the shape of two serpents entwined into each other. Each of the head were a pair of glowing red eyes, and the crystal which was formerly glowing with bright violet-white lights suddenly emitted dark red lights. The dark red lights then intensified into red beams of lights and were focused on Chaos Agumon. The Rookie digimon felt overwhelmed and due to his weakened condition, he instantly dropped to the grounds. The last thing he saw was the crystal hovering closer to him before everything went black.
