A malicious grin was spread across Sky's face…

"Battle!" He declared with fury in his voice, "Meto attack D'Arc, downing flame strike!"

The huge dragon let loose black flames from its mouth engulfing and burning D'Arc causing it to melt before destruction.

Declan LP (4000-3600)

"I activate Meto's effect by using one overlay unit I can make your monsters lose attack points equal to the destroyed monsters attack"

The black flames spread across the ground melting but not destroying the D/D/D monsters.

"Also since you don't control 3 D/D/D monsters Alexander's attack goes back to normal."

Alexander Atk (6000-3000-200)

Genghis Atk (2800-0)

"Rasca knock out that pretender [1], Emperor's wrath!"

"I activate the action spell evasion your attack is negated!" Declan had been silently moving ever since the start of Meto's attack and picked up the card just as Rasca went in for the attack.

"No matter! Urat destroy Alexander! Swift Sword Strike!"

Urat readied his charge and bolted directly for Alexander.

Declan raced for the action card right in front of him and picked it up just in time.

"Action spell miracle! My monster isn't destroyed and battle damage is halved!"

Alexander at this time was just about able to repulse Urat's attack but not before the damage was dealt.

Declan LP (3600-2350)

"Tch" Sky clicked his tongue clearly irritated by this developments "I end my turn, at this moment Meto's effect ends your monsters attack points go back to normal".

Alexander Atk (200-3000)

Genghis Atk (0-2800)

Meanwhile up in the stands the four counterparts were discussing the events of this turn.

"He mentioned four horsemen…" Yuya started with a solemn look on his face and Yuto's arm around his shoulder.

"Also his archetype has changed from 'Numeron' to 'Numeron Chaos', it's the same as when we faced him…" Yuri pointed this out as all four thought back to their encounter with him and how he seemed to devolve further and further into madness as his cards changed into chaos version of themselves.

"I know he only had three cards in his hand but after all that build up where was the fourth one…?" Yugo asked an unusually intelligent question which caught the others off guard.

"Your right…" Yuto replied silently contemplating the situation, rubbing his forehead, "Also the other two monsters effects are unknown they could relate to the summoning of this fourth monster…"

"You're incorrect" a voice from behind the four replied, the four didn't know this voice, wondering who this was they turned around and came face to face with the individual.

He was a boy of 14 years with black spiky hair (similar to Yuto's), red bangs (Similar in style to Yugo's and colour to Yuya) and neon green eyes. He was wearing a black t-shirt with a white jacket tied around his waist, had a duel disk on one arm and a spiked bracelet on the other, brown shorts with orange trainers completed the look.

"Who are you?" All 4 counterparts collectively asked the mysterious individual.

"That isn't important right now….But what is important is that if you see him summon that monster, you intervene as soon as possible." It was clear that even mentioning the monster in question brought back painful memories to the unnamed person, "I was too late last time…I won't let him fall again."

The person took a seat besides the four counterparts and watched closely as Declan began his turn.

"My turn, I draw."

"At this point your Dark Contract's effect activates, you lose 1000 life points!" A sadistic and maniacal Sky proclaimed as he watched the swamp king emerge from the card and rob Declan of a 1000 life points.

Declan LP (2350-1350)

"I activate the effect of D/D/D Rebel King Leonidas from my hand when I take effect damage except during the damage step I can special summon this card from my hand and regain those life points lost." Declan fixed his glasses, as he said this Leonidas emerged onto the field and replenished his life points.

Declan LP (1350-2350)

"Now since I have 3 D/D/Ds on my field Alexander's attack doubles once more! Battle! Alexander attack Urat and end this duel."

"Urat's effect activates! While I control three Numeron Chaos monsters on my field your attack is negated and you take damage equal to the monsters level x200!"

"Alexander's level is 10!" Yuya was looking directly into the eyes of the other person who was wincing in pain.

"That means 2000 points of damage!" A shocked Yuto exclaimed as he watched Urat's sword charge up with electricity and watched in horror as it struck Declan in the heart.

"Actually I won't be taking any damage because as long as Leonidas is on the field no effect can reduce my life points!"

"I activate the action card rejuvenation Alexander gains 1000 attack points and can attack once more! Attack Rasca!"

"Rasca's effect now activates, when I control another Numeron Chaos monster I can force you to attack another monster on the field, I choose Meto!"

"Why would he do that?" Yuya asked the person.

"Meto has another effect…." Was all he could say before Sky announced why he chose Meto instead of Urat.

"Meto's effect triggers when he is targeted for an attack by a monster with more attack points that monster is destroyed and I take no damage!"

Meto spewed out black flames which caused Alexander to melt and dissipate just like D'Arc before him.

"I end my turn."

"I see…you finally figured out how trapped you are. My turn, I draw, I activate a spell card…"

It was at this point the boy shot up from his seat and ran as fast as he could to intervene, "SKY! Don't…"

Sky continued not hearing this desperate plea, "The power of this spell destroys every Numeron monster on my field."

A clearly surprised Declan replied, "Why would you do that?"

"Because doing so allows me to draw three cards from my deck, I now activate the Ritual Spell Deal with the great beyond!"

"Ritual Spell…"

"SKY!" The boy had now arrived on the court and was standing right behind Sky turned around, shock was evident on his face.

"What are you doing HERE?!" Unbridled rage was what could best describe what Sky felt as he picked the boy up by his shirt.

"I followed the tracking device in your Duel disk…I had it implanted in your disk before that tournament…" Sky put the boy back on the ground.

"I won't let you fall back into darkness like you did back home…" Sky's anger was subdued for the time being.

"Earth…" Sky's duel disk deactivated as he fell to the ground.

(1 Hour later) (No POV)

Everyone was standing outside the central duel court. Sky had since recovered from his second collapse in as many days and was standing beside the boy who had appeared during the duel, they were deep in conversation, Sky was leaning against the wall twiddling his thumbs calmly while the other one was getting much more animated gesticulating wildly.

"You shouldn't go around placing trackers in people's disks…It isn't very polite." An emotionless Sky said, this Sky was a far cry from the maniacal one everyone had seen duel Declan just an hour before.

"I did it because I was concerned about my brother is that so much to ask!" The person did a lude gesture before crossing his arms in annoyance.

Another voice perked up from the other side "Brother?" Yuya asked the person.

"Yes Yuya," Sky began "This is my brother Earth…"

Earth under Sky's indication walked over to Yuya and stuck his hand out in a friendly gesture.

"Hello, my name is Earth…Earth Numer." Earth sheepishly said clearly uncomfortable about introducing himself.

"Did your parents hate you or something?" Yugo and Yuri said simultaneously. This response caught the Numer brothers off guard, Earth quickly broke eye contact with Yuya walking quickly to Sky who in turn simply closed his eyes.

"Why would you say that?" Sky asked Yugo and Yuri.

"Well your names are a bit strange just to say"

"I'd tell you if our parents hated us but to be honest we weren't old enough to know before they died…"

"We don't even know our real names…" Earth continued in place of Sky who now had a hand on his brother's shoulder.

"So those aren't your names?"

"That would be correct, at the orphanage where we grew up since we didn't know our names, only that we were related we were nicknamed by the keeper…"

"So how did you both get those nicknames then?"

Sky opening his eyes explained his first "I would often go out and just stare up at the sky wondering what lay beyond and low and behold it was agreed that my name would be 'Sky'."

"With me it was much the same as my brother except, I would study the ground and wonder where everything would end up after a prolonged period of time, so my name would be 'Earth'."

"So now back to the duel…" Declan said staring Sky directly in the eyes.

"What about it?"

"I would like to know what move you were going to make before your brother's intervention."

Sky was biting his tongue wanting to answer to Declan, he couldn't believe how close he came to use that card again. He was near tears, he started babbling incoherently.

Earth intervened yet again "It's none of your business and as you can see it really tears him apart." It was Earth's turn to comfort his brother thinking back to how many times Sky had done this to him. "Now if you would excuse us we need to leave now…"

"You'll do no such thing." Declan was defiant in his message blocking the brother's path out of the building, "I'll need to keep you here for questioning mainly on how you got here…I need your brother as well."

Earth looked over to Sky for advice on what to do next just like he had always done but Sky was now crying still babbling meaningless dribble, Earth was forced to make the decision by himself, "Okay…We'll go with you just so long as you promise not to upset my brother anymore."

"I'll try my best not to upset him. Now if you would just follow me." Declan lead Earth who had Sky's head on his shoulder into his office.

(Declan's Office) (Earth's POV)

I carefully sat my brother down beside me…He was distraught…If I hadn't intervened in his Duel he would've summoned that monster again, At least this time I was able to stop him unlike last time, I'm never losing him again.

"So I would like to know how you two got here in the first place especially you Sky." The Gray haired man across from me asked my brother who was still struggling to answer, I answered in his place.

"I was able to temporarily open a portal to your dimension," I looked towards my brother whose eyes were shut tight, another sign of his reluctance to talk, "I used it to follow my brother who I know from the way he greeted me earlier wasn't too pleased about my arrival."

"Sky how did you get here?" The man coolly asked my brother quickly glancing across I could see the pain in his expression as I heard him etch out the following sentence.

"I t-t-told you…I d-d-don't know-w-w D-D-Declan." His voice was a quiver

"I'll explain one possibility" I began, Sky had turned his head towards me and I returned his glance with a look of sincerity as I reached my arm around his shoulder, "When Sky first summoned that monster a portal may have opened and after his defeat it was very possible that he was sent to this dimension through said portal." Even dancing around the issue Sky was upset as he whispered to me.

"I-I-I was s-s-so c-c-close t-t-to summoning I-I-it…T-t-thanks E-E-Earth"

"I believe that settles that issue…Now back to what I said about the duel."

Sky started to babble again, I told him not to mention it but he did it and now he was going to pay dearly.

I stood up jabbing my finger directly into the man's face "I told you not to do that and now I challenge you to a duel!"

"Why would I want to do that" He replied fixing his glasses which was almost certainly a reflex action.

Looking over to Sky, I sighed regretting what I was going to say next, "If you win Sky will tell you what would've happened had I not intervened."

Sky looked up to me once again with pain in his face. "If you win?"

"We get our wish to leave and get rebuild our lives here!" This had more of a positive effect on my brother as he stopped his pained expression and opened his eyes.

"It's a deal"

(Central Duel Court) (No POV)

Earth and Declan made their way to the court followed by Sky and the four counterparts who made their way to the stands.

[Action Field: Crossover]

[Let's Duel]

Earth: 4000 LP Declan: 4000 LP

Watching from the stands the four counterparts began to ask Sky questions about his brother's skill and deck.

"How strong is he?" A curious Yuya asked.

"What deck does he play?" An inquisitive Yuto questioned.

"Is he a maniac like you?" An insensitive Yugo demanded.

Meanwhile Yuri just remained silent.

"You'll find out" was all a still sad Sky could say.

"I'll go first, Using scale 1 D/D Savant Copernicus and scale 6 D/D Savant Guttenberg I set the pendulum scale and with it I can summon monsters level 2 through 5 all at the same time! I pendulum summon! Emerge my monsters! D/D Berfomet and the tuner monster D/D Ghost, now I normal Summon D/D Necro Slime. I tune my level 4 Berfomet and level 1 Necro slime with my Level 2 Ghost! I synchro summon! Level 7! D/D/D Gust king Alexander (2500/2000)."

"Straight from the off then? I thought about making it longer but suit yourself." Earth was unenthusiastic about the Synchro monster he had seen plenty of them before.

"I then activate the effect of D/D Ghost sending another D/D Berfomet to the graveyard, I now activate Necro slime's effect by banishing it and Ghost from my graveyard I can fusion summon! Appear level 6! Flame King Genghis! (2000/1500).

"Still not impressed…"

"Alexander's effect activates when a D/D is summoned I can special summon a monster from my graveyard reappear D/D Berfomet! Now Genghis' effect activates summoning the other Berfomet from my graveyard!"

"Now it's XYZ you really aren't going to let us leave easy are you?"

"I overlay my 2 level 4 Berfomets to build the overlay network! I XYZ summon! Rank 4! D/D/D Wave King Caesar! (2400/1200)"

"Savant Guttenberg's pendulum effect now activates allowing me to add one dark contract to my hand in exchange for destroying this card…I choose Dark contract with the monopoly seal which I active now since I control a fusion, XYZ and Synchro you cannot use any of those summoning methods!"

"Not impressed, it's hardly worth our time." A bored Earth looked up to see his brother staring at him before he made a particular gesture that was well known to him it meant 'get it over with'.

"Now Earth Numer…So me you're worth my time. I end my turn here."

"It's my turn, I draw" Earth declared determined to win him and his brother their freedom, "Using two Scale 1 Dark Sprit Servants I set the pendulum scale!"

A man in a black robe holding a candlestick with blue flames appeared on both sides of Earth's field.

Sky in the stands smiled knowing what was going to happen next.

The Counterparts could hear Sky mutter "Declan is done for…"

"I activate the effect of the Servant on my left I can destroy the servant on my right and I can place another pendulum monster from deck in his place! I now set scale 10 Dark Sprit Warlord in the scale!"

Dark Sprit Warlord was Similar in appearance to Servant but instead wielded a sword with blue flames on the end.

Earth began a chant as he readied his pendulum summon "Monsters cloaked in darkness punch a hole through dimensions and wipe our slate clean! Pendulum Summon! Emerge from the edge of the world my monsters!"

"Level 8 Dark Sprit Governor Dark/Spellcaster/Effect (2800/2000 SC: 2) and Level 2 Dark Sprit Invader Dark/Fiend/Effect (100/1500 SC: 3)!"

Dark Sprit Governor was similar in appearance to the previous monsters except he carried a with him a set of scales with blue flames engulfing it and invader was the same except he carried a staff with blue flames,

"Invader's effect activates I can tribute this card to destroy one card on the field, so say goodbye to your monopoly seal! Dark Charge!"

"Now all summoning methods are open, The time has come for this duel to close, like I said I wanted it to last longer but you can't put a timer on our freedom plus your fate was sealed as soon as you synchro and fusion summoned!

"WHAT!" Declan and the four counterparts exclaimed while Sky sat back smiling, there was another reason to add to the list on why he liked his brother.

"I now activate the spell, Dark Sprit Synchro Fusion now activate your effect and start the beginning of the end of this duel!"

A swirling vortex appeared in the middle of the court as Earth explained the card's effect.

"This card can only be activated when there is a Fusion and Synchro monster on the field. By banishing one dark Synchro monster and one Fusion monster from my extra deck I can fusion summon a monster that will certainly crush you!"

The swirling vortex grew larger as the two selected cards flew into it.

"Destroy all that oppose us! The monster that commands the battle ground and washes away the sins of the past appear! FUSION SUMMON! Level 12! Dark-Ruler Commanding Light!" Dark-Ruler Commanding Light Dark/Warrior/Fusion/Effect (3500/3000).

"You asked me earlier Yuya how strong my brother was," Sky turned towards Yuya and his brothers. A massive grin on his face "what if I were to tell you that he was the only person who was able to beat me officially in a tournament match!"

Yuya and his brothers realised how much trouble Declan was in now.

"Governor's effect activates, when a monster is fusion summoned I can destroy one monster on the field and deal you damage to the attack points of said monster, I choose to destroy Caesar! Divine Judgement!"

Flames shot out of Governor's scales causing Caesar's destruction and reducing Declan' life points by over half.

Declan LP (4000-1600)

"Commanding light's effect now triggers when an XYZ monster is destroyed on field his attack points are cut in half."

"Why would he want to do that?" Yuto asked Sky clearly concerned about Declan's precarious situation

"If I told you that it wouldn't be fun now would it…?" Sky replied happily while smiling towards Yuya.

"Now I activate light's other effect when its attack points change you take damage equal to the change in his attack!"

"That means Declan's done for if this effect goes through!" Yuya shouted as his brother's leaned in to get a closer look as a cloud of smoke appeared on the field…

Once again sorry for bad reasoning and stuff happening out of the blue

Notes:

[1] This is my obligatory history mention, I also like how the Japanese name for this monster is temujin which is Genghis' actual name
