1500 years ago...
''HEYLIN!'', Dashi roared in front of the crystal palace. He waited there, knowing very well that he'd been heard. Suddenly crimson red flames emerged from the ground, and from those flames walked outside elegantly a tall man, dressed in a royal, chinese, black swordsman costume with red patterns, at his side a long red and sharp sword. His skin was as white as snow and his eyes were as red as blood. His hair was also red and long, going over his tights, and caught in a ponytail.
''Finally decided to show up, Grand Master Dashi?'', He spoke, but not in a taunting manner, his fangs glistening in the sunset. ''Your years of terror will end today Heylin. I shall not allow this to continue anymore!'', ''Have you brought your shiny little toys with you?'', ''Fight me and you shall see.'', Dashi glared at the man.
Heylin looked around in a boring way and asked ''Where is that loyal dragon that always clings to your legs Dashi? I cannot believe he hadn't show up.'', Dashi didn't answer, but instead took a fighting stance, the eye of Dashi hanging at his neck, ''I challenge you to a xiaolin showdown! Whoever stands up at the end of the sunset wins. Let the battle decide the winner.'', a grin coming from the evil, ''Very well then. I shall accept your challenge. But I hope you are aware of the fact that we will fight for more than just for you hoping you'll stop me.'', he took a fighting stance.
''Let's go! Xiaolin Showdown!''
The world changed around them. Crystal enveloped the ground and everything else disappeared. Glass columns appeared all around and the sunset became the time.
''Gong Yi Tan Pai!'', They both yelled. Right after that Dashi charged, they both engaged in a hand to hand battle, until Heylin kicked Dashi in the gut hard enough to throw him in a column. He groaned and when he recovered he narrowly dodged a fist to the head which made a hole in the column.
The Grand Master quickly retaliated, kicking Heylin so hard that his jaw snapped in half. The dark lord regained his posture, turning his attention to Dashi, his jaw slowly placing itself back the way it was, healing fully. Dashi frowned at the sight and dodged another attack, and back flipped away from him, then clenched his hands into fists and roared ''Eye of Dashi!'', the magical artifact at his chest glowed and released a powerful lightning. Heylin extended his hand, palm open, the lightning hitting it fully but disappearing right after that. No mark nor drop of blood was found on his palm, but only steam raising up.
Dashi clenched his jaw tight, eyes wide, ''Aw, is that all? Now it's my turn. Sword of Heylin!'', he grabbed his sword and stabbed the crystal ground with it, right after that it split into 2. Dashi had to jump out of the way onto a column to not fall into the dark abyss.
He growled sweat dropping, and looked at the sun, which was slowly dropping into the skyline. ''Running out of time Grand Master.'', Dashi looked to see Heylin standing on a column in front of him, ''Don't be so full of yourself. I still have a few tricks up my sleeve.'', Dashi growled and threw something in the air. The object started glowing a bright blue, and then from the light appeared a blue creature.
Heylin blinked, his smile dropping, ''The Sapphire Dragon? You can control it?'', He had to jump on another column to dodge the fire. The dragon hissed and blew fire again and again and again. Having enough of it Heylin glared and clenched his sword which started glowing. Then he slashed with his sword towards the dragon, a wave of flames emerging from them. The Sapphire Dragon blew fire towards it but the red flames came closer and engulfed the wu, forcing it to become the way it was before with char on it.
The evil persona landed on a column and looked around, then above him to see Dashi with his palm open but glowing, and nine glowing dots on his forehead. Heylin didn't have time to raise his sword as he only took a step back, Dashi's hand slashing like a light sword at his face. Heylin slashed with his sword at Dashi who dodged, both of them jumping on another column. Heylin slowly opened his left eye where the attack had damaged his skin. He healed himself and wiped away the blood, but then felt something. Gently brushing the skin he felt a deep scar in there. He was immortal, he couldn't get scars, and yet...
Looking at Dashi he wore a pissed off expression, his sword glowing. ''Aw, are you mad? Actually, it suits you.'', Dashi Smirked and jumped in the air with the Star Hanabi in hand. ''Another shiny little toy?'', '' You haven't seen this one. Star Hanabi!'', The wu glowed and shot a giant wave of flames, ''What the-'', The flames fully hit him, and as he fell to the ground he roared in pain, and crashed down.
Dashi landed on another column, and as the smoke cleared he saw Heylin in one knee, supporting himself on the sword. He panted and looked at the sun which was only half visible now, ''Alright, I admit it, that had a bite to it.'', he got up ''But not enough!'', jumping and hovering in the air he released an tremendous amount of dark energy from his body. The dark aura forming dragons that were flying right at Dashi. ''Golden Tiger Claws!'', Dashi used the wu to teleport away to another column, and to give himself time to use another technique. As the dark spirit followed him, his fists glowed and he roared ''Repel the beast!'', and punched the Dragon's head, making it disappear. He then saw Heylin coming towards him, sword in hand. ''If you won't stay down, then I'll make you. Eye of Dashi! Star Hanabi'', ''Sword of Heylin!''.
Dashi's combined attacks were slashed in half by the mighty blade, which itself released a burst of flames that came towards Dashi rapidly. Seeing this he yelled ''Two Ton Tunic!'', after that the attack hit him fully. He fell onto the ground, the tunic back to normal. Shaking he slowly got up and looked at the sun. By the looks of it he only had 5 more minutes.
He got up on shaky legs, groaning. Heylin approached him at a slow, elegant, pace. The Grand Master glared and went for a punch which was quickly dodged and retaliated by a punch in the gut that made him cough brutally and back away.
''I admire your devotion Dashi. But you see, devotion isn't enough, and you don't have time anymore.'', The sun was almost down, and Heylin raised his sword, but when he brought it down it was blocked by another weapon, an axe. And Heylin knew that axe. Taking his surprise as an advantage Dashi kicked him hard in the gut and brought the axe down yelling the wu's name ''AXE OF JUDGEMENT!'', a light engulfed both of them and a giant dragon made of light appeared and roared, and flew down, just as the axe made it's way towards the dark lord's chest, hitting him fully.
As Heylin roared out in pain the sun disappeared from the skyline, ending the battle.
As the environment become back to normal Dashi placed the axe over his shoulder, looking down at Heylin. The last said groaned and looked up at Dashi, in a shaky voice managing to say ''Where did you got my brother's wu?'', ''That shouldn't be any of your concern, but since you asked so nicely, he visited me in a dream, and when I woke up it was next to me.'', Dashi shrugged as he answered. Heylin placed his head down and laughed at the evening sky weakly, ''That old fart.''.
He then felt his sword being taken away from him, and saw Dashi holding it above his head, ''Seriously? Are you going to kill me using my own Shen Gong Wu?'', ''Not kill you with it.'', Heylin made a face in confusion, then he realized what Dashi meant. He turned into a shadow as quick as he could but Dashi stabbed him in the chest with the sword, the shadow and the body disappearing and the red sword's blade turned black now, then slowly changing it's color into red again, sealing the power of the evil persona.
From behind a rock Dojo appeared and crawled towards Dashi, going around his neck and hugging his head ''I knew you could do it!'', ''Are you sure, I mean I can swear I saw you chewing your claws as I was on a column up there.'', Dashi smirked at the dragon, ''What? No, my claws are a bit too long so I thought to bite them off a little you know what I mean?'', ''Mhm...'', Dashi looked back at the sword.
''What are you going to do with it now?'', ''Now that he's done for, we need to make sure no one gets their hand on this thing. We have to hide it. In fact, we have to hide all of them.''.
What Dashi didn't know was that Heylin didn't die.
All the xiaolin dragon warriors were training outside with their weapons when Master Fung quickly ran to them with Dojo in his arms, ''My young dragon warriors! There is an important task awaiting for you!'', at that everyone stopped and looked at their worried master. Fung didn't look so pale ever since he heard about the Heart of Jong, and Dojo was contorting himself in his arms more than he was usually doing, he literally became a knot. ''What's wrong? A wu?'', Kimiko asked trying to untie Dojo who was trembling badly.
''AV-AV-AV-AV-AV-AV Not just any wu! THE SWORD OF HEYLIN HAS BEEN REVEALED!'', Dojo shouted. ''What's the fuss about it? Is it like... super powerful or what?'', Raimundo asked, Fung took the ancient scroll of the Shen Gong Wu out of his sleeve and opened it, ''It is more than powerful. This is one of the two most powerful wus that have ever been created, one of the first.'', ''One of the first Shen Gong Wu?'', Clay asked incredulous. ''Yes.'', The scroll showed a sword with a dragon head on it ''It is said that there were two brothers, one created a wu for good, the other a wu for evil. Those 2 were the first wus ever created. Both of them having the exact same amount of power.'', ''The sword of Heylin is the wu made by the evil brother, and if fallen in the wrong hands-'', Dojo said ''Let me guess, 1000 years of darkness?'', Raimundo tried ''Worse.'', Dojo answered, ''The sword has a power that can split the world in two.'', as Fung said that the scroll's figure cut down with the sword, showing a ball to be cut in two.
''This is not good! We must get the sword before the forces of Heylin misplace their ragged hands on it!'', Omi shouted, ''It's 'before the put their dirty hands on it', Omi.'', Raimundo corrected his tiny friend, ''That too!'', ''Well what are we waiting for?! Let's go!'', Dojo said changing his form into his huge dragon form. As the xiaolin monks climbed on his back Fung said ''Be careful my young warriors, this isn't just any mission. Evil is anywhere. Especially right now.''.
Jack Spicer was minding his own business, reading from a book in front of his fireplace and occasionally sipping some wine from his glass. Right when he was about to take another sip he tensed, looking up but his gaze slightly unfocused, looking like he was starring off into space. He slowly closed the book and got up.
