-Flashback: Within Barian World, moments before Yuma's awakening-

In his damaged form, Vector was heading towards the Barian Sea, an acidic pool of massive water where legends told of a great power sealed within.

And Vector wanted it.

"I'll get my revenge! Astral and Yuma are going to pay! They may have defeated me but our little battle is far from finished. Next time I'll crush them once and for all!" Vector stated as he stepped into the water, ignoring the acidic properties of it as it ate away at him, but his hatred and desire for revenge made him continue as he dove in.

And soon, after traversing trough the agonizingly painful water, Vector's eyes widened as he had found what he had been looking for, the seal to the Barian deity, Don Thousand.

Wasting no time, Vector swam downward, parts of his wings breaking off as he went deeper and deeper, but he still didn't care, all that mattered was the power he would receive at the end of his ordeal.

'All I require is the strength. And if the ancient Barian legends are true, then I'll definitely find that power here in the darkest depths of the great Barian Sea.' Vector thought as he continued to swim, until he came across a glowing crack.

And once inside, he was left speechless and thought, amazed, gazing upon a seal, which looked like an evolved version of the Barian emblem.

'Yes this is it the sacred resting place of the great Barian deity, Don thousand!' Vector thought before he held up his right hand, which began to glow with a great heliotrope coloured power and then slammed it on the crest embedded in his chest.

"Don Thousand, I offer you my life force in exchange for your great power." Vector offered, pulling a blank Card from out of the red crystal on his crest, causing the seal to break a part in a massive explosion, consuming Vector, as a great surge of energy was released and shot out from the waters and into the sky, causing all of Barian World to quake at its power.

Moments later, Vector regained consciousness, groaning in pain as his body had been further damaged before the maniacal Barian looked in awe at the dark figure now standing before him.

"Don Thousand?" Vector questioned in awe.

"You awoke me to plea for a favour, the gift of my power, why?" Don thousand asked, to which Vector replied. "There's someone I must defeat once and for all but I can't do it without your help."

Don Thousand's red eyes glared down at Vector as he asked. "You speak of Astral?"

"Yes." Vector replied bitterly, before adding in an equal tone of hatred. "And his pest of a friend, Yuma Tsukumo."

"Give me the power to defeat the and I'll do whatever you ask." Vector then said, to which Don thousand replied. "Discover the locations of the seven Mytherian Numbers."

"Seven Mytherian Numbers?" Vector asked, never hearing of such Number Cards.

"Retrieve them and we will be unstoppable." Don Thousand stated.

"If that's what it takes to defeat Yuma and Astral, then consider it done." Vector replied, before demanding. "Now, your power. Give it to me!"

"As you wish." Don Thousand replied as he then pierced his claws straight through Vector's chest and grasped the purple crystal where his heart was supposed to be, making Vector scream out as Don Thousand's grasp tightened.

"Your life belongs to me now. In exchange I will infuse your being with my power." Don Thousand told vector as his dark form forced itself through Vector's chest and into his heart, causing the damages he had sustained in his Duel against Yuma and the ones he had inflicted upon himself to reach the Barian deity to regenerate.

"From this day forward, you and I will be as one." Don Thousand said as Vector's body was enveloped in dark red energy that gave him power he never reamed was possible.

However, the power was too great and Vector blacked out.

Once awake, he found himself before the Barian Sea, before he stood up and laughed, knowing now he could not be defeated by Yuma, Astral or anyone that dared to stand in his way.

And while Don Thousand had told Vector to retrieve the Mytherian Numbers, Vector had another wicked idea to rid his life of Yuma and Astral.

Meanwhile in the main hall of Barian World, Dumon and Mizar were highly concerned at what was happening as the ground continued to shake and red lightning stormed the skies.

"This could be the end of Barian World." Mizar stated in a nervous tone, to which Dumon reassured his Barian comrade. "It would take an incredible force to destroy an entire world."

"But that's exactly what's happening." Dumon and Mizar heard Vector state, before they turned to see him walking up to them.

"Vector?" Dumon questioned, wondering if the maniacal Barian had anything to do with the situation.

"Even as we speak, Astral is using his growing strength to threaten Barian World." Vector told Dumon and Mizar, falsely accusing their nemesis to cover his own tracks.

"If that is true then the fault is entirely yours'." Mizar stated in reply, causing Vector to act all innocent and ask. "How can I be to blame? After all I'm the one who tried to stop Astral."

"You tried and failed!" Mizar snapped back in reply as he then told Vector. "And now thanks to your recklessness Yuma and Astral have grown stronger than ever."

"I was defending our world, while you seem to be obsessed with Kite and his Galaxy Eyes. I'd never do anything so foolish." Vector replied, which only enraged Mizar and caused him to snap at Vector once again. "Feel the wrath of my Galaxy Eyes and we will see who the foolish one is!"

Not wanting to divide the Emperors, Dumon stepped in and said. "This is not the time, Mizar."

Mizar groaned in frustration, knowing Dumon was right and knowing he wouldn't get the chance to strike down Vector and his smug attitude.

"As you know Astral has long been a threat to us. Many ages ago he even defeated our great deity, Don Thousand and cast him into the depths of the great Barian Sea. If continues absorbing Numbers, he'll soon be in a position completely destroy Barian World. But never fear Vector is here and I have a new plan. One that will rid us of Astral once and for all." Vector said.

Curious, Dumon asked. "What is it?"

"It's a secret. And only time will tell." Vector replied, chuckling as a portal opened up behind him, before he vanished, leaving Dumon and Mizar perplexed at what Vector had in store.

As the portal opened up, Vector was confused at his surroundings for he was still in Barian World.

"Don Thousand, is this some kind of joke?" Vector asked, before saying. "I thought you said you could lead me to Yuma and Astral."

"I have taken you to them." Don Thousand replied as he then explained in reply. "You should be thankful, I have accomplished something almost impossible for a Deity in this current state to perform. I have crossed back through time and space to pursue Astral."

"Are you saying we traveled back in time?" Vector asked.

"Correct. With the unique energy Astral has been exposed to from his creation in Astral World, I was able to follow him. And adjacent to this world is the Real World and those you seek." Don Thousand replied.

"So this is Barian World when it was young? Anybody home?" Vector asked as he checked out the surroundings.

He then smirked as he noticed five Baria Crystals, each containing five familiar faces, none other than the five Barian Emperors, including another Vector, who was in suspended animation.

Walking up to the Baria Crystals, Vector approached his slumbering counterpart and told him, resting the Crystal as he spoke. "Hey there, handsome. I'd love to let you out so we could cause some real trouble together, but I know me too well and I expect it'd be only a matter of time before one of us double-crossed the other. And I think it would be you. Or is it me?"

Vector laughed, amused by his verbal antics.

However, his laughter stopped and his eyes turned spiteful, as he could see, from the corner of his line of sight, two more Baria Crystals in the shadows.

And while the shadows blocked the figure's identities, Vector knew too well who they were.

"Nash and Marin!" Vector said as he could feel his hatred building up as he made his way over to the final two Emperors.

"You have no idea how much I despise you two. How much I hate you!" Vector told the Barians, before a wicked thought filled his mind, making him say in a sinister tone as his claw-like fingers began to glow and a sphere of energy formed in his right hand. "But I have a way to fix that."

"Hope you two are having sweet dreams because they are about to become eternal!" Vector exclaimed, pulling his right arm back as he prepared to shatter and destroy the pair.

However, his body suddenly froze up, before he heard Don Thousand's voice boom in his head. "Vector, cease these actions at once!"

"Don Thousand?" Vector questioned, struggling to move on his own.

"You cannot destroy your fellow Emperors. With such an alteration, you could destroy all of Barian World." Don Thousand told Vector in a highly serious tone.

"I don't care. So long as I can destroy these two, I don't care what happens!" Vector snapped back in reply, before the maniacal Barian tried his hardest to regain control over his body, but only cried out as he could feel Don thousand grasp tightly upon his dark crystallized heart.

Slowly releasing his grip, which caused Vector to stop and collapse on all fours and gasp out, Don Thousand then told Vector. "Calm yourself, Vector. Remember, Nash and Marin get what's coming to them in the future and you still have other problems to deal with."

"Alright..." Vector managed to reply, knowing if he tried to go after Nash or Marin again, Don Thousand would continue, placing his body in a world of anguish, to which he then opened up a portal to the Real World, ready to confront Yuma and Astral.

In the Real World, Vector was now in his human form, looking for any signs of Yuma or Astral, unsure of where he was.

"Where are those two? And where am I?" Vector asked himself, to which a fly landed on his shoulder and replied. "I may be of assistance."

"Heartland?" vector questioned, before asking in demand. "What are you doing following me?"

"I was hoping you would change me back. I hate being stuck in this form!" Heartland replied in a whiny tone, which only caused Vector to grab Heartland and say as he began to crush his tiny fly body. "Beat it, Heartland before I pull your wings off."

"Wait a second Vector, you can't just leave me here." Heartland gasped, before saying as Vector loosened his hold. "Look, if I help you, you promise not to crush me."

"Fine." Vector replied, before saying to his pest of an ally. "Now make yourself useful and find out where we are."

"Right away, sir." Heartland replied, flying away and leaving Vector alone to think about his plot for revenge against Yuma and Astral, two thorns he'd be happy to remove from his side and destroy.

But soon, Heartland returned, landing on vector's finger, before he asked. "So where or when are we?"

"From the looks of it, we're at Duel Academy." Heartland replied.

"Duel Academy?" Vector questioned, before saying. "I remember Yuma going on and on about this place and some famous Duelist who studied here."

"You mean Jaden Yuki." Heartland replied, before saying. "What he lacks in his studies, he more than makes up in Dueling."

"Really? He may prove useful to me." Vector thought out loud, thinking to use Barian's Force to brainwash Jaden, only for Heartland to ruin his mood and state. "I'm afraid that won't be possible. Just as Astral is able to protect Yuma from the power of Barian, so too does Jaden have a unique gift to protect him."

"But all's not lost. We've come at a very interesting time. It seems Yuma and Astral have allied themselves with Jaden and some other Duelists to take on a group known as the Society of Light." Heartland said, which caused awicked smile to appear on Vector's face, hearing another group out there that was having trouble dealing with Yuma, to which Vector said. "Maybe I can use this to my advantage."

-Moments later-

Within the White Dorm, three students, two males and a female, were standing before Sartorius' room, guarding their leader as he was in the middle of a conversation with Sakura and Hinata and didn't wish to be disturbed.

However, the front doors burst open, before an unknown individual to the Light stepped inside, causing the three students to activate their Duel Discs, ready to protect Sartorius.

However, their opponent only smirked as his hand suddenly changed to a silver coloured claw, while a twisted and unusual looking Duel Disc burst from his arm, before he held up a single Card that radiated with an intense red energy.

-With Sartorius-

The leader of the Society of Light smiled from hearing Sakura and Hinata's loyalty after using his power to brainwash them fully.

However, the three were interrupted as screams echoed from just outside his chambers, before an unknown figure then burst through the doors and asked. "Anyone home?"

Stepping before him, Sakura and Hinata each drew Kunai as Sakura then said. "Don't worry Master Sartorius, we'll protect you."

But before either could react, Vector shot past them both at an incredible speed, knocked them down and disarmed them.

After witnessing the intruder's speed and power against the two well-trained Kunoichi, Sartorius asked in a curious tone. "I can tell you are no ordinary Duelist. Who are you and what do you want from me?"

"You can call me Vector." Vector replied, before saying. "And I want what you want, the destruction of Yuma Tsukumo and the rest of those troublesome Chosen brats!"

Hearing Vector's reply, Sartorius asked curiously. "Interesting. You know of the Chosen Duelists?"

"Let's just say a little fly told me all about what was happening and I came to offer my assistance." Vector replied, before saying. "I know you want the Kyuubi, That's why I have come to offer you my power."

"Give your power and add it to mine. With that, I can make it so the Nine Tails will crush all those who oppose us, partner." Vector said, holding out his right hand, which Sartorius took into his own and shook hands with the Barian.

However, as the villains of separate timelines shook hands, Vector thought to himself wickedly. 'You are a fool Sartorius. With your power, I won't stop at Yuma, I'll crush you and this entire island!'

While Vector smiled, mentally smiling in wickedness, Sartorius thought to himself. 'Nice try Vector. But I know all about you thanks to Yuma, so I'll keep a close eye on you to make sure my goal to help all of mankind see the Light. And when you're no longer needed, I shall dispose of you alongside Jaden and the other Chosen Duelists.'
