Natsu was able to make it to his tower and to take on Zancrow, an arrogant duelist that has no regard in hurting others. His Black Flame deck has burned up some of Natsu's life points with him down to only 500. Zancrow had 3300LP. He also had his Black Flame Crusader at 2100atk points and Black Flame Exploder at 1800atk points. All Natsu had as defense was his Scale Guard with it weakened to 1300def points.

"Black Flame Exploder, you're first. Take that little lizard down." Zancrow said. The spiral of black flames slammed into Scale Guard, but Scale Guard had a shield around it and blocked the attack.

"Did you already forget that my Scale Guard has to be attack twice in order to be destroyed?" Natsu said.

"Of course not." Zancrow said. "That's where Black Flame Crusader comes in. He'll crush that lizard." His black flame humanoid swung its scythe and destroyed Scale Guard.

"Rats. It's a good thing Scale Guard is an earth attribute or else his Crusader would have gotten stronger." Natsu said.

"I think I'll end my turn. Come my next turn is when I'll destroy you." Zancrow said.

"Natsu's really starting to fall behind." Wendy said.

"No joke." Gray said. "That Zancrow guy isn't lighting up the slightest."

"We can't give up on him, guys." Lucy said. "Natsu's found a way to pull out of these jams before and he'll just do it again. We just need to have faith in him."

"It's my turn!" Natsu said as he drew his next card. "I activate Passion Draw. Since you have two monsters on the field, I'm able to draw two cards." He draw his two cards and saw it was Igneel and Happy. "Look at that. My best card and my favorite little buddy. I think it's time you get in on the action. I summon Happy Flying Cat." His blue cat with wings flew out with 300atk points.

"A cat?! You've got to be kidding me." Zancrow laughed.

"Careful. My little buddy might not look all that tough, but he does have some punch to his attacks." Natsu said. "For example, he can fly through your monsters and attack you directly. Max Speed!" Happy flew right past the monsters with great speed and rammed his head right against Zancrow and slammed into his head with Zancrow's life points dropping down to 3000.

"Okay, I guess that wasn't bad, but it's going to take a lot more than that." Zancrow said. "Especially since your fur ball is going to be taken down instantly. One attack from either of my monsters and that cat is going to turn into a rug for me to clean my shoes with."

"That's only if you can touch him and I'm not going to let that happen." Natsu said. "I activate the Protective Instinct spell card. After my monster attacks, this card can switch him into defense mode." Happy changed modes and he had 200def points. "Also, as long as he stays in defense mode, he can't be destroyed and I won't take damage. It's your turn."

"My pleasure!" Zancrow said as he drew his next card. "I think it's time I put an end to this. You're about to see the being that will lead to your destruction."

"Does that mean what I think it means?" Natsu said as he already had an idea as to what is coming.

"You got it." Zancrow said. "I sacrifice both my Black Flame Crusader and my Black Flame Exploder to bring out the being that will destroy you!" Both his monsters turned into pure light and flew up with them forming the heart and it started beating.

"Oh no. It's coming Natsu!" Erza said as they were all starting to get worried.

"Come forth, Underworld Lord Booturo!" Zancrow said. The heart unleashed the dark energy and something was rising from the ground. A giant bat rose with yellow markings around it. Booturo unleashed a mighty shriek with 3000atk points.

"Yikes! I really don't like bats." Lucy said as all of them were a little shook up by the new Underworld Lord.

"These Underworld Lords seem to be getting bigger!" Gray said.

"And uglier." Lucy said.

"And scarier." Wendy said.

"How's Natsu suppose to protect himself against that?" Erza said.

"Hahaha! I guess this is where it ends for you because my Underworld Lord is attacking you directly!" Zancrow said. "Underworld Lord Booturo, send this pathetic excuse of a duelist to infinite darkness." Booturo unleashed a mighty sonic screech and it seemed like the end of Natsu.

"I don't think so." Natsu said as Happy stepped in the way of the attack.

"Hey, down in front!" Zancrow said. Happy was able to project a barrier and block out the attack

"Did you forget about my Protective Instinct?" Natsu said. "I take no damage as long as the monster who I used it on is in defense mode."

"You just got lucky is all." Zancrow said as he placed a card facedown. "Why don't you just admit you're beaten and stop beating around the bush?"

"It's not over until the last card is play." Natsu said and drew his next card. "This will work. I'm activating my Straight To It. My spell allows me to use the effects of a trap in my hand or deck if I send that card to the graveyard. So I'll use the effects of my Five Star Dragon Egg trap. That means I can summon a level five or higher dragon to the field."

"Level five or higher? That can only mean one thing." Erza said

"Igneel is coming out to play." Lucy said as they were all starting to think he could win.

"I summon Igneel the Fire Dragon!" Natsu said. Natsu was surrounded by fire and it flew straight into the sky with its mighty roar and 2500atk points. "You're finished. With Igneel attacking and Happy defending, a couple rounds and you're going down."

"You still think you can win?" Zancrow questioned. "Let's see if you're still thinking that after I activate my Divinity Flames trap." More of Zancrow's black flames surrounded him. "Good luck trying to get to me now. My trap prevents you from attacking me directly."

"Are you serious?!" Natsu said.

"That's right and if you can't attack me, you can't win." Zancrow said.

"Great. Now he's got to figure out how to get past that trap of his." Gray said.

"But they're in a stalemate now." Lucy said. "With that trap protecting Zancrow and Happy protecting Natsu, neither of them can deal damage to the other."

"Perhaps, but it's only a matter of time until one figures out how to get past their defenses." Erza said. "Whoever can do that, we'll have the winner."

"No matter what you do, I will find a way to win and bring all my friends back." Natsu said.

"Your friends?" Zancrow said. "You mean those couple old men that Hades sent to the shadows? Why don't you just face the facts that you can't beat me? I can already hear their screams and cries from the people you failed."

"You're making me sick." Natsu said as he gripped his own hand from anger. "You don't seem to have any respect for life at all. You don't care if the people are your friends or enemies as long as you get to see someone suffer. So there's no way I'm going to lose to a guy like you?"

"Will you just shut up about all this noble stuff of yours?" Zancrow said. "It's getting annoying. Just hurry up and finish your turn so I can send you to your demise and I can continued my ways of destruction."

"Is that all that dueling is to you?" Natsu said. "It's wrong. Dueling suppose to be about fun and forming bonds. It's not some sort of tool for you to hurt others!"

"Dueling is for fun and making bonds?" Zancrow questioned and started laughing. "Just when I thought you couldn't get any more pathetic. Dueling is nothing more than beating your opponents down and having them at your mercy. If that's all you're going to talk about, just shut up and keep going. There's nothing you can say or do that will make me change my mind."

"I can't believe you." Natsu growled. "What's wrong with these guys? This isn't what dueling is suppose to be about. Isn't that right?" Natsu looked up towards Igneel and Igneel looked back. Natsu felt some sort of connection and could tell that Igneel felt the same way he did. "Yeah. I am right."

"I said shut up and finish your turn! You're really starting to annoy me." Zancrow said.

"You asked for it! Thanks to Straight To It, I'm allowed to draw an extra card." Natsu said. "I won't let you diminish everything Makarov and others have taught me about dueling. Gramps told me that dueling is all about having fun, improving your skills, and forming bonds of friendship. That's how Fairy Tail runs and anyone who threatens it is going to pay!" Natsu's mark glowed brighter than it's ever felt before.

…

Laxus

Laxus finished his duel with the tower deactivated and was on his way to meet up with the others. He noticed his mark was glowing brighter as well. He pulled over and wondered what was going on.

"Natsu?" Laxus said as he could feel him. He also noticed his deck was glowing and saw Heaveledge's card fly out. "Heavledge? What's going on?" Heavledge came out in its spirit form and flew off with Laxus wondering why this was happening.

…

Natsu

Natsu was about to draw his next card, but he heard Igneel unleashed a powerful and mighty roar. Natsu heard another roar and looked to the sky and saw Heavledge was flying towards them.

"Heavledge?" Gray wondered as to why it was here.

"Does that mean Laxus is here?" Wendy said.

"I don't see him." Erza said. Heavledge flew own and entered Natsu's deck. Somehow, Natsu's strong feelings towards Makarov allowed Heavledge to come to him. Natsu drew his top card and saw Heavledge was there.

"Hold on. How did Heavledge get in my deck?!" Natsu said. "How am I suppose to use him? Everything depended on that draw." His other card, Dragon Fusion, began to glow as well. "Wait. Is he telling me to use this?" Natsu wondered why and saw the image of something flashed before his eyes. "Okay. Let's do it. I'm activating Dragon Fusion."

"Dragon Fusion?" Zancrow questioned.

"That's right. Now I can fuse two dragons together." Natsu said. "I fuse Igneel and Heavledge together!"

"What? The dragons can fuse together?" Zancrow said. Both dragons flew up into the sky and merged together in a fusion of fire and lightning.

"I fusion summon….Igneel the Lightning Flame Dragon!" Natsu said. Igneel flew out in a new form with him surrounded by a flaming aura with sparks of lightning. It also had 3300atk points.

"Look at that thing!" Lucy said.

"Such power!" Erza said.

"No matter how impressive your monster is, you still can't attack me or my Underworld Lord." Zancrow said.

"That's where you're wrong." Natsu said. "Your Underworld Lord isn't safe because Igneel can rob it of its attack points and all its abilities. Lightning Heater!" Igneel shot out bolts of lightning that blasted Booturo with its attack points dropping all the way to zero.

"It's powerless!" Zancrow said for there was nothing he could do to stop him.

"With your Underworld without power, I can attack it freely and finish you! Igneel, attack with Lightning Flame Impact!" Natsu ordered. Igneel flew right at Booturo and slammed right into the bat. Igneel blasted right through the Underworld Lord and destroyed it. Zancrow was blown away from the impact, strangely laughing, as his life points dropped to zero. Zancrow instantly turned to dust as soon as he hit the ground.

"He won!" Lucy cheered as they were all glad he did. Natsu stared at his new dragon and he saw it as symbol of everything Natsu learned about dueling. Igneel and Heavledge separated and Heavledge flew back to Laxus.

"Thanks for the help." Natsu said. "These guys working for darkness need to understand that this isn't what dueling is about. It's about fun and making friends. That's what the guilds are for. They won't get away with this!" He declared as he has more of a reason than ever to stop them.

...

Hades

The dragons weren't the only one who could sense and see what was happening. Down in the underground, Hades was sensing what was going on as well.

"Three of them have been defeated." Hades said. "It would seem I underestimated our enemies. I can't leave it all to our two newest recruits. It seems I'll have to take action myself."
