10. Corruption.

After the fight with Grave we learned that the Crystal Star is at the highest tower of the castle. But a barrier blocked the entrance.

A woman had the only key to break the barrier.

That woman turned out to be Ruby Mowz, Mallow fought her Duel Drone throughout the castle, in the end Ruby was found on the roof and Mallow won the Duel but Ruby threw the key away then she escaped.

'Well there goes the key...' Mallow sighted.

'What did expect?' Luigi replied: 'That she would hand over they key just because she lost? These kind of things only happen in movies or games.'

Mario shook his head. 'We'll never find that key.'

The shadow in the tower watched as the group took the stairs down, he quickly moved to another window only to see Mario and the other leave the castle.

'Well where do we start?' Luigi asked the moment they stood outside.

'We start by using logic, she threw the key from the other side of the castle.' Mario started to walk

Five minutes later they reached the other side of the castle.

'She threw the key in a straight line.' Mario continued he looked up to the roof of the castle. 'We stood somewhere in the middle...' He continued, Mario pointed at the roof, he drew an imaginary in the air: 'There is some wind.' Mario continued the line with his finger. 'So the key must be somewhere between the points the grass starts...' Mario slowly said he walked up to the grass, he quickly took a glance at the roof. 'And this creek of water.' Mallow hung his head: 'Well one lucky thing, the X-Nauts can't get to this Crystal Star either.' He sighted.

'We'll get that key, we only need to divide our forces.' Mario sternly said.

'We draw an imaginary line through the middle of the castle, Luigi you search the grass left of the castle, I take the grass right, Mallow you take the waterside left and Goombella takes the waterside right.'

After searching for half an hour Goombella suddenly approached Mario. 'I found the key!' She yelled, five minutes later Mario had gathered the others and they all stood at the waterside, the key was stuck between some water plants. 'I tried to get the key loose with a stick, but it didn't work.' Goombella sighted.

'Just wait, I'll get it.' Mallow said, he took some kind of windscreen and a towel from his backpack. 'Mallow why do you carry that around?' Goombella wondered. 'Well you know in case we find a beach.' Mallow replied he put the screen up and started to undress himself. 'Don't peek!' Mallow shouted, then they heard water splashing and Mallow yelling: 'The water is fricking cold!' A few minutes later Mallow stood on dry land, his towel wrapped around him, he was shaking from the cold. 'Mario.' Mallow started: 'I swear you owe me one!' Mario smiled. 'Indeed I do Mallow, I shall repay you one day.'

When Mallow was dry and dressed again, they headed back to Hooktail's Castle once they reached the roof, Mario slammed the key in the lock, a hight screech came from the door as the magical barrier was dispelled, the door slowly opened only to reveal a winding staircase.

After a climb Mario and the others entered the huge round chamber, it was a messy room, since one of the walls was broken the floor was covered with rubble, for the rest there were windows everywhere, ragged curtains were attached to the ceiling, huge bones littered the room and in the center of it stood Hooktail. 'Hooktail you're finished!' Luigi shouted.

'Don't try.' An all too familiar voice said.

'You.' Mario growled as he saw a figure standing under Hooktail's head.

'Hooktail will only attack when I command her.' The man continued.

'Mayor Koops.' Mario said as the figure stepped from under Hooktail.

Koops was looking different, he wore a black, trench coat and black pants and boots. 'So Hooktail is a machine.' Mario said.

'You say it like you knew all along.' Koops replied.

'I did.' Mario said with a chuckle: 'When Hooktail first attacked, I heard something creaking, when you showed up to chase Hooktail away, I saw you press something on your sword, presumably a button, before Hooktail backed away.'

Koops laughed. 'So you were onto me, and yet you didn't expose me?'

Mario shook his head: 'I wasn't sure though, and even if I was I wouldn't do it because of those poor people, they believe in you! Why did you do it?' Mario asked. 'Simple.' Koops replied: 'I chased Hooktail away even before I was mayor, when I saved Petalburg, I was sure to become mayor, only problem was the old mayor...' Koops stopped there.

'Right you talk about Shhwonk.' Mario said with a serious voice.

'Wait that Nephilim?' Goombella stammered. 'That Goombella, was no Nephilim.' Mario bluntly said: 'So Koops that has been bothering me, what happened to Shhwonk?' Mario asked.

'Simple.' Koops replied: 'The old mayor was onto me, so I had him poisoned, that poison made it so he believed he was a Nephilim, the old mayor adopted the name Shhwonk, when the old mayor dressed in black clothes, I told the people about the Nephilim and that Shhwonk was one of them, of course the people asked where their mayor was, I told them Shhwonk killed him, I defeated Shhwonk and so in the new elections after saving the village twice I became mayor.' Koops explained.

'And I guess from time to time you let Hooktail attack so you can chase him away to strengthen your position?' Mario asked, Koops nodded in response. 'But two things I don't get.' Mario said.

'Shoot.' Koops reacted. 'If I had a gun I would.' Mallow whispered to Luigi who needed to suppress a chuckle. 'When I confronted Shhwonk, he was trapped in a rock, how the hell did you manage that?'

Koops laughed at Mario's question. 'Same way I made the barrier and key, magic. You see I killed the old mayor, after my fight with him, I took the confused mayor to the nameless ruins, there I killed him and sealed his soul within the rocks there, the ruins got named Shhwonk Ruins and nobody dared to go there.' Koops paused for a second: 'Anyway, Shhwonk as a spirit strongly started to believe he was in fact a Nephilim, he gained some magic and cursed the area around the ruins, he became a nuisance but you solved the problem for me.'

Mario nodded. 'My second question did you use a Crystal Star as a power source for Hooktail?' Mario continued. 'Yes I did use a Crystal Star for Hooktail.' Koops confirmed.

'You have any idea what you are dealing with?' Goombella asked.

'Yes I do.' Koops replied: 'I deal with a few pesky people, who need to begone.' Mario sighted. 'The Cross-Naut army, they look for Crystal Stars, I already dealt with one of their people in the dungeon, they know that Crystal Star is here.'

Koops simply laughed: 'Let them come Hooktail shall crush them! Now begone before I have Hooktail crush you!' The mayor shouted.

'And what if we stay?' Mallow said in a mocking tone.

'You really want to get the blood from under my nails don't you?' Koops sounded annoyed. 'I just want to know what your plan is Koops, you are mayor, people love you, what are you after?' Mario asked.

'I shall tell you, if you leave after that!' Koops growled through his teeth: 'What I want is control. Nephilim, the X-Nauts, the Wicked and Egyptian Gods, all is going through hell, I want to unify this island group, then take my fight to New-York, once I rule there I slowly move out through all the world! I might even take all the Crystal Stars and see what the infamous legendary treasure is!'

'So in the end it is power?' Mario sighted: 'The same the X-Nauts want, you are no hair better then they...' Suddenly Koops interrupted Mario: 'ENOUGH! I am sick of you! All the time I was weak and scared! Then one knight the Crystal Star crashed in this castle, my father gathered a search party and went to search for the Crystal Star! He never returned! I gathered all my courage, I found the bones of the search party scattered through the castle, but no sign of my father when I entered this room I found him dead with the Crystal Star in his hands.' Throughout his story the voice of Koops changed it became more dark, a black shadow started to form above him. 'Enough.' Koops spoke his voice sounded deep and dark now, with a bit of his own voice mixed into it. 'I shall kill all of you, you annoy me.'

Luigi stepped to the front, his D-Gazer activated. 'AR vision - link established.' The computer voice spoke, Koops activated a standard D-Gazer. 'Luigi be careful! He is possessed but we don't know by what!' Mario warned his brother. 'I know Mario, don't worry I am careful.' Luigi replied.

(Puppet Koops: 8000) - (Luigi: 8000)

'I shall start.' Koops spoke, he looked at his opening hand.

'I set three cards facedown.' He started. three cards materialized horizontally on the Field: 'I end my turn.'

Luigi looked at Koops with suspicion, but he saw nothing in Koops' expression. 'Does he have a bad hand? Does he use Trap Monsters?' Luigi thought by himself.

'I'll play it safe, one monster in defense mode and that's it.' Luigi stated a horizontal card appeared in front of Luigi.

'Then it is my turn.' Koops said with a smug smile on his face.

'I activate Super Guard.' Koops pressed a button on his Duel Disk one of his Continuous Spell cards spun around. 'As long as this card remains on my Field, I pay 500 Life Points during my Standby Phase, but all my monsters cannot be destroyed by battle.' Koops explained.

'Now I shall activate Card Destruction.' Koops continued, he played the Spell card, Koops discarded his three cards then drew new ones, Luigi discarded five.

Suddenly a card appeared on the Field. 'I discarded Elegant Light LV 4 from my hand by a card effect, this means I get to Special Summon one Level 4 or lower monster from my Deck.' A weird purple and gray monster appeared before Koops, it was a drone-like robot with one optical eye at the bottom, it stood on three longs legs. (800 ATK)

'As long as Trap Sluzer is face-up I am not affected by Continuous Trap cards.' Koops explained. 'Finally I set another card facedown.' He continued and another card appeared in his Spell/Trap Zone.

'Finally I activate The Dark Door and end my turn.' Koops concluded, and another Continuous Spell card appeared.

'I don't really get this guy, what is his plan? Well we'll see.' Luigi thought.

'Draw!' Luigi shouted.

'I activate two Trap cards.' Koops then stated, the first was a card named Gachi Battle, then next to Koops a monstrous cash register appeared, it had eyes and a huge mouth filled with sharp teeth.

'Let me explain.' Koops said: 'Gachi Battle forces you to Special Summon a monster from your Deck during your Main Phase one and destroy it during your End Phase, then my second card Monster register, this one costs me 1000 Life Points to activate, but when a monster is summoned the controller must discard cards equal to the Level of said summoned monster.'

(Puppet Koops: 7000) - (Luigi: 8000)

'I see.' Luigi then said: 'A Mill Deck, that explains the set-up, but it ends here!' Luigi shouted. 'But first summon a monster from your Deck.' Koops said. Luigi took a card from his Deck. 'I summon Avian!' Luigi shouted and the bird-man hero clad in green appeared striking a pose. (1000 ATK)

The Monster register showed a 3, Luigi took the 3 cards from his Deck and discarded them.

'I hope you have a back-up plan here, because I am about to ruin your strategy! Heavy Storm!' Luigi shouted as he played the Spell card.

'And you think I am that stupid?' Koops sneered.

'Go Dark Bribe!' The mayor shouted as his Trap card spun around, Heavy Storm was destroyed and Luigi drew one card.

'I have to beat him down before my Deck runs out.' Luigi started to sweat.

'Avian attack!' Luigi commanded, Avian shot green feathers at the Trap Sluzer but the monster stood firm.

(Puppet Koops: 6800) - (Luigi: 8000: Deck: 24)

'I set one card and end my turn.' Luigi stated, one card appeared in his Spell/Trap Zone. 'Since you ended your turn Avian is destroyed.' Koops said and the Elemental HERO exploded.

Koops drew his card. 'I pay 500 Life Points for Super Guard and because of Trap Sluzer I am unaffected by Gachi Battle.' Koops took one card from his hand, it appeared in his Spell/Trap Zone. 'I shall end my turn.'

Luigi drew his card. 'My Gachi Battle activates.' Koops said with a sneer.

Luigi took a card from his Deck. 'I summon Burstinatrix!' In a burst of flames the black-haired woman clad in the red bodysuit appeared. (1200 ATK) Monster register hit a 3 and Luigi discarded that many cards from his Deck. 'Next.' Koops continued: 'I activate my facedown card: Foolish Revival!' The Trap spun around. 'This card enables me to summon one card from your Graveyard to your side of the Field in defense mode!'

Next to Burstinatrix, Avian reappeared he crouched down and crossed his arms. (1000 DEF) Monster register showed another 3 and Luigi discarded his cards again. 'Burstinatrix attack Trap Sluzer!' Luigi commanded, Burstinatrix threw two fireballs at the monster but again it survived.

(Puppet Koops: 6400) - (Luigi: 8000: Deck: 16)

'Keep attacking fool, it merely tickles me!' Koops sneered.

'I set three cards and I end my turn.' Luigi said ignoring the mayor, the cards appeared behind his monsters, then suddenly Burstinatrix exploded.

'Look at whatever is left of your Deck! A few more turns and I shall end you!' Koops shouted he drew his card. 'Yet he seems not faced, his facedown cards, they are the problem, he has faith in those, well I shall ruin it!' Koops thought. 'First I pay for Super Guard.' He said.

(Puppet Koops: 5900) - (Luigi: 8000: Deck: 16)

'Next I activate Tribute to the Doomed.' Koops played the Spell card, the mayor discarded one of his cards then the ground below Avian broke open the HERO got mummified and dragged in the hole. 'Now we got rid of that one I summon a monster!' Koops played another card, next to Trap Sluzer another drone-like robot appeared, this one was green with red legs, it had a camera on top of its round body. (500 ATK)

'This is Card Sealer.' Koops said: 'When this card is summoned, I can pay 1000 Life Points, as long as this face-up monster is in attack mode the facedown Spell and Trap cards you control cannot be activated!'

(Puppet Koops: 4900) - (Luigi: 8000: Deck: 16)

Luigi's knees started to shake, he started to sweat again.

'Looks like I sealed your only chance, just as I sealed your fate.' Koops said, he took a card from his hand. 'I activate another Card Destruction.' Koops' Spell card appeared, he discarded his two cards and drew new ones, Luigi discarded his four cards and drew new ones.

(Puppet Koops: 4900) - (Luigi: 8000: Deck: 12)

'I end my turn there.' Koops said, Luigi drew his card.

'And another card less in your Deck!' Koops laughed: 'Anyway you know what comes now, Gachi Battle!'

Luigi took a card from his Deck. 'I summon Sparkman!' Lightning struck the ground and a warrior clad in yellow armor appeared striking a pose. (1600 ATK) Monster register showed a 4, and Luigi discarded the cards from his Deck. 'Only six cards left in your Deck.' Koops reminded Luigi.

'Sparkman attack Card Sealer!' Luigi shouted once again ignoring Koops, Sparkman created a ball of electricity in his hands and fired it at the monster, Card Sealer stood firm.

(Puppet Koops: 3800) - (Luigi: 8000: Deck: 6)

'I must end my turn now.' Luigi said, Sparkman exploded.

Koops drew his card. 'I pay 500 Life Points for Super Guard.' Koops stated his Life Points decreased a bit. 'Now I activate the Spell card Set Burn!' The mayor played the card and it appeared briefly on the Field.

'I shall explain.' Koops said: 'You must discard one card from your Deck for every Set card on your Field, and you have one set monster and four Spell or Traps cards, so five in total.' Koops said that as if he was a teacher explaining a simple math problem to a child.

Luigi discard all but one card from his Deck.

(Puppet Koops: 3300) - (Luigi: 8000: Deck: 1)

'I shall end my turn, and so should you, this Duel is over.'

Luigi simply smiled. 'Koops I have been keeping track of the cards you forced me to discard.' Luigi said.

'You're not gonna tell me that the last card in your Deck is the card you need!' Koops shouted Luigi simply nodded as he drew his card.

'The effect of Gachi Battle cannot be activated as I have no cards in my Deck left.' Luigi said.

'I Flip my set monster Clayman!' The set card disappeared and the Warrior clad in heavy brownish armor appeared. (800 ATK)

'Now I activate the card I just drew.' Luigi continued as he played it. 'R - Righteous Justice!' The letter R appeared in the sky. 'Now I can destroy Spell and Trap cards equal to all Elemental HERO monsters I control, and I choose to destroy The Dark Door!' Luigi shouted, Koops' Spell card exploded.

'So what?' Koops sneered: 'You have only one monster, and you cannot destroy my monsters because of Super Guard, and your set cards cannot save you because of Card Sealer.' The mayor sneered.

'I am working on that, but first I activate a Spell card from my hand, Enemy Controller!' A huge controller appeared in the air as Luigi played the card, the controller plugged into Card Sealer. 'Up, Left, Down, Right, A!' Luigi shouted, Card Sealer changed into defense mode. (100 DEF)

'The only weakness of your Trap Sluzer and Card Sealer, they only work when in attack mode.' Luigi sneered.

Koops started to sweat. 'Now.' Luigi stated: 'I activate my set card O - Oversoul!' The first of Luigi's cards spun around. 'This let me summon one monster, in this case Sparkman!' The electric warrior appeared with the strike of lightning. (1600 ATK)

'Next up is H - Heated Heart!' Luigi shouted as his second card spun around. 'This gives Sparkman 500 extra Attack Points and a Trampling Effect!' Lightning surrounded Sparkman as he powered-up. (1600- 2100 ATK)

'Followed by my Call of the Haunted!' Mallow continued this time Avian appeared on the Field. (1000 ATK)

'Then I activate Pot of Avarice!' Luigi's third card spun around, he took five cards from his Graveyard and placed them in his Deck Zone, then he drew twice.

(Puppet Koops: 3300) - (Luigi: 8000: Deck: 3)

'Finally I activate Hero Flash!' Luigi yelled and his last facedown card spun around in huge letters the word HERO appeared in the sky.

'I Banish from my Graveyard H - Heated Heart, E - Emergency Call, R - Righteous Justice and O - Oversoul!' Luigi took the four cards from his Graveyard and he pocketed them, the letters started to flash.

'This allows me to summon one monster from my Deck.' Luigi started, he took one of his three remaining cards and played it, Burstinatrix appeared in a burst of flames. (1200 ATK)

Monster register showed a 3. 'Yeah, yeah I know.' Luigi growled as he discarded his remaining cards.

(Puppet Koops: 3300) - (Luigi: 8000: Deck: 0)

'All that for nothing!' Koops laughed: 'Even if you attack my Trap Sluzer with all your monsters you can only deal 1900 points of damage!' The mayor grinned. 'Didn't I mention?' Luigi calmly said: 'With Hero Flash, all Elemental HERO Normal monsters I control can attack directly!'

Before Koops could even react he got hit by a fireball from Burstinatrix, the green feathers of Avian and a lightning strike from Sparkman, then Clayman charged in and punched the mayor in the stomach, Koops bent forward before he fell on the ground groaning from the pain.

(Puppet Koops: 0) - (Luigi: 8000: Deck: 0)

'Luigi well done.' Mario said giving his brother a pat on his back.

'Mario I was lucky that R - Righteous Justice was the last card in my Deck, if it wasn't I wouldn't have won.' Luigi watched as the holograms disappeared he deactivated his D-Gazer and Duel Disk.

'Nobody could guess he would use a Mill Deck.' Mallow spoke: 'If we knew we could have prepared for it, Luigi as Mario said you did great, I would have lost my nerves and just gave up.'

Luigi looked hard at Mallow. 'Mallow you are so tough, you fought Smithy and what more and survived. The worst thing I faced was Exodus, but Mario had it the worst first Dimentio, then Princess Shroob...'

But Goombella stopped Luigi. 'Luigi you really did great, you faced Exodus and won, this... man should be no problem!' She shouted.

'But still...' Luigi cowered. 'ENOUGH! Mario shouted and slapped Luigi on his cheek, that seemed to wake him up.

'Aftershock of a Shadow Game, nobody noticed but Koops initiated a Shadow Game that would slowly seep fear into his opponent for every card drawn.' Mario explained.

'Then why did it take so long for Luigi to be affected?' Mallow wondered.

'Adrenaline.' Mario replied: 'Luigi's adrenaline level was high as it is, he never noticed the effects of the Shadow Game until now.'

Mario approached Koops. 'Will you surrender?' He asked the mayor.

Koops sat on his knees, he looked at his hands with empty eyes, black mist poured out of his nose, until the room was filled with it. 'What happened?' Koops stammered, then the mist shot back inside his body, Mario clenched his fist and parts of the darkness was drawn toward him.

'Mario you...' Goombella started. 'Yes I can control the shadows, how do you think I managed to beat Grave in the dungeon?'

Mallow looked at Luigi and Goombella. 'I found out already, Mario will do something about it after the Shadow Queen is defeated.' Mallow quickly spoke.

'Anyway, whatever possesses Koops is done for.' Mario closed his eyes, his shadow armor appeared around him, he grabbed the black mist with a shadow fist of his own, Mario yanked the mist out of Koops.

'You won't have me!' A demonic voice shouted, before the shadow got pulled out of Koops it managed to draw Koops sword, press the button to activate Hooktail then threw the sword out of the window.

With a cold laughter the demonic mist disappeared.

Hooktail slowly moved its head, then it opened its eyes, spread its wings and crashed through the roof, Mario created a barrier of shadows to protect everyone in the room, then Hooktail broke down the other walls by flying through them before it landed again, its maw opened and a burst of fire shot out, Mario dodged out of the way then grew shadow wings.

'Mallow, take everyone outside to the roof, I shall deal with Hooktail.'

Mallow grabbed Koops and lifted him over his shoulder.

Hooktail let out a roar then took the skies again, Mario followed the robot.

Hooktail roared again before it began to shoot flames again, Mario sensed the pattern and dodged out of the way, he created some shadow blades in his hands and started to throw them at Hooktail, they simply bounced off of the metal skin of the robotic dragon.

Hooktail slowly turned around and Mario quickly turned with Hooktail.

'Got it.' Mario said to himself: 'It roars before it attacks and it can turn slow, I might be faster, but I cannot maintain these wings forever...'

Mario quickly scanned Hooktail, then he saw them the joints between the wings. 'Weak point of the joints are on the front side, so I need to face him head-on, problem is the flamethrower.' Mario mumbled, he gave Hooktail time to face him.

Hooktail roared, at that time Mario created an orb of shadows in his hands, when the jaws of Hooktail shot in place he fired the orb into the gaping maw of the dragon, since the flamethrower was plugged Hooktail couldn't shoot, the flamethrower started to turn red before it exploded, blowing the jaws clean off, then Mario charged in with a sword made of darkness and slammed it between the joints of Hooktail's left wing.

The wing started to creak before parts started to fall off, the dragon crashed down onto the remains of the highest tower, the tower started to gave way and crashed down as well, destroying a great part of the castle's roof, Hooktail managed to land on the roof.

Mario landed in front of the dragon his shadow wings disappeared.

Hooktail rose its front-right paw as if it wanted to crush Mario, Mario reacted by dashing to the left, then stuck another shadow sword between the knee joints, the dragon tried to move its foot back but the sword blocked the joints, with another lout creak half of the knee came off, the dragon lost balance and crashed down, Hooktail let out a weak roar, Mario created another shadow sword and rammed it together with his fist through the dragons eye, when Mario retracted his arm he had a handful of wires, Mario pulled the wires out.

Meanwhile Hooktail used his remaining right wing as its missing right leg, then Mario noticed that fuel was dripping out of Hooktail's eye.

'A huge contraption like that needs several fuel sources, the Crystal Star must drive the body enable it to move, but without fuel, the Crystal Star can't work, it is lucky that the fuel tank is in the head.

Mario looked at the orb blocking the flamethrower: 'I wonder...' Mario said with a grin, he used a shadow hand to retract the orb, inmediately flames bursted out of the broken maw, Mario created a shadow shield, then a huge explosion took down Hooktail and a great deal of the castle, Mario saw a star shaped object made of diamond getting launched from the remains of Hooktail, then the castle started to crumble, Mario looked where his friends were then created a forcefield to safely lower them and himself to the ground.

As soon as Mario touched ground his shadow power disappeared.

'Mario.' Luigi then spoke, his voice was shaking: 'That was awesome!'

Mario started to blush then the Crystal Star landed in front of him, the moment Mario wanted to touch it, the Star got taken away by some black mist. 'Thank you, I needed that.' The demonic voice sounded, before the shadow flew off in the direction of Petalburg.

'What the hell is that demonic shadow thing?' Mallow asked.

'Can't ask Koops he seems to be unconscious.' Mario noticed.

'It can't be good though and besides we need that Crystal Star.' Goombella added.

'Whatever it is, clearly it is no Nephilim.' Mario stated: 'During Smithy we faced Semi-Gods who's aura was powerful then we had Dimentio who was worse, recently we got Exodus whose aura is a bit worse and then we have this demonic aura...' Mario paused for a second: 'My prediction is we might face something as a real God this time, but whatever it is let me deal with it.'

Next time:

With Koops exposed and defeated the Crystal Star was in reach.

But then it got taken away by a powerful, dark aura, it clearly is no Nephilim, but what is it? A Semi-God? A real God? Or something completely different? Find out next time. ''Dragon Slayer.'' Coming next.
