In the vastness of space, a massive demonic creature was eating a whole planet. It was large as a building, had three centipede like tails, and a gaping maw and armor.

This was the demon whose appetite never runs out. Great Feind, Yamigedo. Ruler of the clan of evil monsters comprised from different worlds. This clan is called "The Hundred Demons".

Above the destroyed planet, eight stars appeared, one of them took the form of a chinese dragon.

"Im afraid we are too late." the dragon said.

"This makes the fourth world he's destroyed and counting." said a voice almost similar to Asmodai.

"And what of the next world he'll encounter?" another voice said.

"We must protect it, and the universe, at all costs."

"But who are we to defy fate?" a voice similar to Kiri asked.

"Were the Great Eight, ya dink."

"Let's go. The time is now!"

The stars then began to circle around the world the beast was on as they spun.

"Empowering the forces of Earth, Water, Fire and Air! We summon all souls that came to Dragon, Beast, Demon and Deity to safeguard the world of humans from this titan of terror!" they all said.

(Cue Opening-Luminize)

I'm running to the sky

Two dreams we keep inside

No matter what challenges may come our way

Illuminating guide

Our power amplified

As we race for the hope of tomorrow!

My phase for the dream. Luminize for the future.

Are you ready to draw? Let's believe it and raise the flag!

Always here next to you

feeling you in my soul

Our trust is all we have that we can depend on

Holding this courage here as I embrace my fear

I want to flood the darkness with the rays of the sun

I remember the days of my youth

You taught me the meaning of what is the truth

My desires are stronger than before

With my mind so free

I'll protect everything that I believe I have the will to achieve.

Luminize your soul

tension is running high

as the timing for our hearts beat as one in sync

A pillar for the world

A place we can be free

to begin a brand new future here now!

Are you ready to draw? Let's believe it and raise the flag!

Outside of the world, the group was in their ships slowly beginning to touch the atmosphere.

"Whoa. Feels like forever since the last time we were here." Rainbow said.

"Its hard to believe it. I cant wait to see Gao again." Hope said.

"Man, youve really got a connection with that guy." Kazuichi said.

"Come to think of it, wasn't this the world where Despair kidnapped you and your friends?" Mukuro said.

"It was. I didnt want it to be brung up, but…" HOpe said.

"Hey! You guys might wanna come and see this!" Natsu said.

On the TV, a large chinese dragon with armor and holding a red orb was flying across the sky and coiled around the sky tower.

"Is that a monster?" Sonata said shaking. "A big scary snake!"

"Its a dragon, not a snake." Odd said.

"Wed better get over there. It just pinned down a buddy poice officer, and used buddy fight cards!" Hope said.

"Yeah and...wait, I don't see Natsu anywhere." Jexi said.

"Oh youve got to be kidding me…" Hope said as they saw Natsu on a strange bike.

"Heh. He stole some chumps bike." Aria smirked.

"Isn't that your bike?" Korra asked as Aria looked.

"What the hell? He better not get it scratched!" Aria said.

They continued to watch the Dragon as it held Paruko hostage.

"I'll say it again. I am looking for the strongest fighter in this part of the section of the universe." he said.

"So you wanna buddyfight? Then look no further!" a voice said as Natsu pulled up to the dragon.

"Its not you, but…" he said. "Hah! Is that the smell of Igneel I detect on you?"

"It should be. I'm his son." Natsu said.

"So he really did raise someone to be a dragon slayer." he said. "Please… let me apologize for making you lose him to that dreaded Acnologia."

"Not your fault. But don't worry about Acnologia, cause I'm gonna slay that monster into dragon dust! Now, we gonna buddyfight or what?" Natsu asked.

"Im sorry to say, but youre not from this world in particular. I am looking for the strongest fighter on THIS world." the dragon said.

"Say WHAT?!" Natsu said. "Aw man, whos powerful enough to take you on?"

"Hey! Sorry I took so long!" a familiar voice said as Gao flew up on his Buddy Skill, drum flying right behind.

"Gao?" Natsu said before noticing a Buddy Police Badge. "Wait, youre in the Buddy Police?!"

"Well, sort of…." Gao said.

"Oh, like a trainee huh? I get it." Natsu said.

"But i wont be for long. But anyways, when were you gonna tell me you were coming back, Man? Its been too long." Gao said,

"A-hem." the Dragon said. "What are you doing here, child?"

"You wanted the strongest fighter on this world right?" Gao said.

"A mere child like you could never possibly be the one i seek." he said.

"Easy there, gramps." Drum said. "You can keep Paruko, we don't really care. But the condition is for you to defeat Gao."

"How could a mere boy be a fitting opponent for me?" he asked.

"I thought you were looking for the strongest buddy fighter, well here he is!" Drum said. "Between us dragons, theres no one stronger than him."

"I see. I accept the challenge, but know you must train a hundred years before challenging me." he said. "And to make up for my rejection earlier, how about you join the fight on my challengers side, young Dragneel?"

"Fine. Besides, fighting other dragons sounds cool. Now, tell me who you are, old lizard!" Natsu said.

"It has been many moons since anyone has used it. I have forgotten it." he said.

"Huh?" they both said.

"Ha! Had you going there, didn't I?" he said as the two face faulted. "Im surprised Ignell didnt tell you of me. Tenbu. Fifth Omni Dragon Lord, Tenbu."

"NIce to meetcha. Now lets fight!" Natsu said.

"If you are ready, let us see what Igneel has taught you." Tenbu said as one of his whiskers reached out to his orb. "My bravery will shine brightly on this day. Luminize! Bright Formation!"

"Yeah! Been awhile since I've played this game! Breathing Fire and taking names! These guys are all fired up! Luminize! Roaring Red Dragons!" Natsu said.

"Ready, Drum?" Gao asked.

"Oh yeah!" Drum said showing a new form with arm drills and bright blue armor. "Sculpting my body with red hot flames! Carving out a path with my own two fists! Crimson Battler, Drum Bunker Dragon is reporting for duty!"

"Hey Indigo, if you can hear me, Im gonna use that saying for your deck!" Gao said.

"Go ahead! I got a new one anyway, its all yours!" Indigo said.

"Burning like an inferno, with limitless spirit! Luminize! Crimson Dragon Fist!" Gao said.

"Now let's buddy…" Paruko began.

"Fight!" they all said.

"Raise the flag!" they said.

"I fight for Dragon World!" Gao said.

"Dragon World for me too." Natsu said.

"I also fight for Dragon World." Tenbu said.

"Tenbu has the first move!" Paruko said.

"Charge and Draw! I call Extreme Sword Dragon to the center!" Tenbu said. "Attack Gao!"

Extreme Sword Dragon charged at Gao as it slashed through him.

10-7

End of Move.

"Now its Gao and Natsus move! Per team ups with fighters and heroes, both can take their turns simultaneously!" Paruko said.

"Draw! Charge and Draw!" Gao said. "I call Crimson Battler, Extreme Blow Dragon to the right. Then I call Crimson Battler, Break Shoulder Dragon to the left! Then I equip Crimson Fist, Dragoblaze!"

"Nice ones!" Natsu said. "I'll follow up by calling Fly Trap Dragon to the right, then I'll call Venom Harpe Dragon to the center!"

"Natsus not going full offense?" Happy said.

"Did you not see the new dragons Tails added to Natsus deck?" Carla asked. "He figured that he should change up the strategy." Carla said.

"Now, let's get the party started. Fly Trap, attack Extreme Sword!" Natsu said as Fly Trap took out Extreme Sword. "And I think I'll end things here for now!"

"I'll take it from here, then. I'll hold off on extreme blow, but attack with Break Shoulder Dragon!" Gao said.

"Not so fast! I cast Dragon Breath!" Tenbu said destroying Break Shoulder.

"You asked for it. Ignite! Crimson Fist...Dragobrave!" Gao shouted punching Tenbu.

10-7

End of move

"I call Boomerang Dragon to the right, Extreme Sword Dragon to the center and Systemic Dagger to the left!" Tenbu said. "Boomerang, take out Extreme Blow!"

Boomerang Dragon spun in the air as he took out Extreme Blow and returned to Tenbu's hand. "Extreme Sword and Systemic Dagger, attack the human boy." Tenbu said.

Both dragons leapt into the air and attacked Gao.

7-2

End of move

"WHy arent you gunning for me?" Natsu asked.

"You have Venom Harp Dragon in your center, am I not correct? Were I to attack you, I would waste both of them on you. None left for the human." Tenbu said

"Well, Id better get your attention then! Draw! Charge and Draw! Now, I equip Dragonblade, Drumsword!" Natsu said as a sword appeared in his hands as he jumped to the left. "Fly Trap, Venom Harpe, link attack Systemic Dagger!" Natsu said as both dragons attacked it. "Now I attack the fighter!"

7-5

"My turn now. I call two Spin Nail Dragons to the left and right!" Gao said.

"If he gets through with all the attacks, we win!" Natsu said.

"First Spin Nail attacks Extreme Sword, the the second attacks Tenbu!" Gao said as both dragons attacked.

5-3

"Now Crimson fist!" Gao said.

"No chance! I cast Green Dragon Shield!" Tenbu said.

3-4

End of Move.

"I thought you were gonna win, you two! If you lose, i'll be this dragons hostage!" Paruko said.

"Would that really be so bad?" Natsu asked.

"Hes right, beautiful. Won't be long now." Tenbu said winking at Paruko. "Draw! Charge and draw! Now, I'll buddy call myself."

"What?! Is that even allowed?" Natsu asked as a second Tenbu phased out of the original.

"Dragon Lord Tenbu has entered the battle!" the second one said.

"Also, you should know. When I enter the field, I eliminate all of my opponents monsters." the first one said.

"Take this! Howling Fire!" the second one said launching a ball of flames that obliterated natsus monsters, but not gaos.

"Hey, how come your monsters didnt get wiped?" Natsu asked.

"Because I casted the spell, The Skies in your Hand!" Gao said. "It returns all monsters on my field into my deck."

"You said your name was Gao Mikado. You are much better than I thought. But...I still have my attack!" Tenbu said as the second one attacked.

"I cast Blue Dragon Shield!" Gao said as Tenbu only bit into the shield.

"Ow! I think you chipped a tooth!" Tenbu said.

"Quit your whining gramps!" Drum said.

End of move.

"Okay! Draw! Charge and Draw!" Gao said. "I buddy call my buddy, Drum to the right!"

"About time! I was getting bored here. Crimson Battler, Drum Bunker Dragon is here! Let's do this!" Drum said.

"Then I call Spin Nail to the left and we're gonna do a link attack!" Gao said.

All three of them attacked the second Tenbu.

"And drum, remember when I hold a fist item." Gao said.

"I gain the penetrate ability." Drum said.

"Did you say penetrate? Doesn't that mean I'm gonna receive three damage points?" Tenbu asked.

"Guess you aren't just a pretty face." Drum said attacking Tenbu.

5-2

"I still have two life points left."

"Not after me and Gao are done." Natsu grinned holding a card as Gao did the same.

"Two impacts at the same time! I can expect Natsu to use that one." Hope said.

"Thanks for clearing the field for me Tenbu. Makes this so much easy." Natsu said. "You have less than four life and I have no dragons in my center. I pay three gauge and discard one red dragon to call...MY FINAL PHASE!"

"And will Gao use Roaring Slash, Gargantua Punisher?" Toma asked.

"Now I cast!" Gao said as a large fist appeared behind him. Gao entered the fist as it closed its fingers as it rocketed towards Tenbu while at the same time, a large red dragon appeared behind Natsu as it charged a shot.

"Let's show this lizard...why we're the best!" Natsu said. "Blaster Tornado, Roaring Red Dragon Lord!"

"Gigantic...Crusher!" Gao said as both impacts launched at Tenbu.

"This is gonna hurt…!" Tenbu said as both attacks hit him dead on.

2-0

Game over! Winners: Gao Mikado and Natsu Dragneel.

"Thats how you finish the fight!" Hope said as thier ships flew down to Tenbu.

"Now, you wanna tell us why you wanted to challenge Gao?" Toma asked.

"I sought out the strongest fighter on this world because they will be the only person to prevent the overwhelming threat that is to come to this world." Tenbu said.

Suddenly, the sky turned dark and it started to rain. In the air, a dark figure flew high above them before he launched lightning at Gao as Drum blocked before it flew at Tenbu as he grabbed their hand into Tenbu's eat and eating something before he vanished in a bolt of lighting.

"Who was that?!" Sakura asked.

"And did i see him eat something outta Tenbus brain?! Gross!" Nami said.

"Quick. Tell us about the threat!" Hope said.

"Huh? What threat?" Tenbu asked.

"Thats what he ate. He ate your memories." Hope said.

"Who ate?" Tenbu said before they all heard a rumble as multiple portals opened in the sky.

"Uh oh. Those a definitely portals to other worlds." Tails said. "And not just a few. Counting them up...looks like 100."

"100?!" Daisy said. "That's impossible!"

Monsters were slowly coming out of each one.

"Looks like they come from different worlds too. Dragon, Katana, Danger, Magic, Ancient, Legend, Dungeon, Darkness Dragon even Hero." Tails said.

"Bring it on! I'll fight all of ya!" Natsu said.

"Natsu, wait!" Lucy said as each monster turned into a card and started flying off as the clouds parted.

"Where are they all going?" Cyrille asked.

"Where ever they are going, theyre definitely demons. Gray, it think youre gonna have to put in a lot of time as a Devil Slayer." Ichiro said.

"Yeah. I know. They're the things I slay after all." Gray said.

The hundred cards flew back to the same man as he was drawing darkpower from a monster. Likey the same monster that destroyed the planet.

"Aw, dont tell me youre hungry already?" he asked. "So give me more. More of your power so that I may devour this planet, and the rest of the universes!"

It let out a warning growl.

"Yeah, yeah, I know. I sensed that Ice Devil Slayer too. But do not worry, Great Yamigedo. Leave it all to the, the all mighty Ikazuchi!" the boy said.
