So this is it... The Duel that was teased at the end of Dark Side of Dimensions, but never shown. I'll be going with relatively all the rules and card effects the series has established. I'm going to try and use the majority of cards that Atem and Kaiba have been confirmed to have, but sometimes there will be exceptions.

All rights go to 4kids and Yu-Gi-Oh. I own nothing except this story.

"Speech."

'Thoughts.'

"I knew you'd be here." The man standing before the throne, overseeing the castle and Egypt, wearing the Millennium Puzzle around his neck was none other than the Pharaoh Atem.

"Then you know why I'm here." And the man standing before him. The modern-day Seto Kaiba. Wearing his technology armor, merged with that of the Plana's magical energy in order to transport his spirit into the Afterlife temporarily. He smirked at the Pharaoh, he had found him at last.

Atem wasn't surprised, it was like he knew Kaiba was coming here to duel him. In fact, it wouldn't be so surprising if he did know. "Then let us begin." Atem held out his left arm and immediately, a flash of light summoned a Duel Disk that appeared on his arm, the same of which he used for most of his time with Yugi while in the future.

"Are you sure you want to go through with this?" Priest Seto asked Atem, he didn't normally trust abnormal people wandering into the castle like that.

"I'm sure." Atem reassures that there was nothing to worry about. "Please, no one interfere with this unless by my command." He directed to everyone around them. Now there would be no interruption.

"Kaiba, just because you took great pains to get here, doesn't mean I'll go easy on you." Atem told his persistent rival. He readied his deck, as did Kaiba.

"The same to you." Kaiba had his deck ready too. The strongest and most powerful he could conjure up. He knew Atem was strong, too strong, so he was in for a long duel. But in the end, his desire to win at last drove him forward. "May the best duelist win."

"Well then, I just have one thing to say."

"IT'S TIME TO DUEL!" Atem declared and this battle of the Eternal Rivals would now begin!

Atem: 8000 LP

Kaiba: 8000 LP

"I'll go first. Prepare to duel Pharaoh and prepare to be defeated!" Kaiba draws a card, bringing his hand to six.

"If that's what you believe, then try it." Atem chuckled a little. Kaiba's track record didn't show him winning any time soon. 'And may the heart of the cards guide you. If you have chosen to believe in it or not.'

"Believe me, I will." Kaiba wasn't taking defeat for a result this time. His determination this time, to do this was immeasurable and he would do all in his power to make sure no one interrupted this duel. Kaiba looked at his cards for a moment and then knew what he was going to do. "First I summon the mighty Vorse Raider in attack mode!" Vorse Raider appears and ready for battle. One of Kaiba's signature starter monsters. "Then, I'll put two cards face-down, that's it."

"Very well." Atem draws a card. He looks at what he had and thinks for a moment. 'Yugi, though I'm without you. I am strong because I know you'd be supporting me even from another life.' He thinks, remembering the good times and then refocusing on the duel. "I summon Queen's Knight in Defense Mode." Queen's Knight appears in Defense Mode. "Next I'll put these two cards face-down. That ends my turn." This was only the first turn. Nothing big just yet... 'Kaiba, just because I've beaten you multiple times in the past, doesn't mean I don't respect you. Nor does it mean I don't take you seriously. But that does mean, I won't go down without a fight.'

"If that's all you can do, then I've already won." Kaiba's move once more. He drew a card. "I play one more card face-down." Kaiba sets a third card face-down. "Now Vorse Raider, destroy Queen's Knight!" Vorse Raider charges at Queen's Knight with his large sword and slashes at the knight.

"I play, Zero Gravity." Atem reveals a Trap Card. "This Trap card changes the positions of all the cards on the field. So your Vorse Raider is switched to Defense Mode." Vorse Raider stops its attack and goes into Defense Mode, while Queen's Knight changes into attack mode.

"You're just delaying the inevitable. I end my turn." Kaiba ends his turn for now. Vorse Raider was best left for now.

"We'll see." Atem draws a card. "I summon King's Knight." King's Knight appears with Queen's Knight. "When King's Knight and Queen's Knight are in play, I am able to automatically summon Jack's Knight." Jack's Knight appears from Atem's deck in attack mode. Now he had three monsters.

"Next I activate the Spell Card, Royal Straight. By sacrificing my three knights. I can summon the Royal Straight Slasher!" Poker cards rain down on the field as that monster was summoned. Royal Straight Slasher, a powerful card.

Kaiba narrowed his eyes. He was there when Atem played this card before, he knew what it could do.

"Royal Straight Slasher's special ability now activates. I send from my deck to the graveyard, one monster of each of the first five levels."

"Level 1, Watapon, Level 2, Old Vindictive Magician, Level 3, Sangan, Level 4, Winged Dragon, Guardian of the Fortress, Level 5, The Tricky!" Atem sends those five cards to the graveyard.

"In doing so, my Slasher is able to destroy all the cards on your field!" Slasher sends a massive blast wave at Kaiba's field.

"I think not! I activate my Trap! Fiendish Chain!" Fiendish Chain shoots out and binds Slasher. "This trap binds your monster so it can't attack or activate its abilities." Kaiba was prepared for that ability.

"Not bad Kaiba." Atem complimented. "Save the compliments." And it was immediately told to be saved. "In addition, when Sangan is sent to the graveyard, I'm able to add a monster card from my deck to my hand." Atem does just that. "With that I end my turn."

Kaiba draws a card. "I activate Cost Down. This card lowers the level of every monster in my hand by 2. So now I'm able to summon." Vorse Raider shatters. "Blue-Eyes White Dragon!" With only a single sacrifice.

"Take a look Pharaoh, this monster represents all the anger I've built up against you. The scars you've left on me and my monster want revenge. Now attack Blue-Eyes! White Lightning!" Kaiba declared. Blue-Eyes attacks immediately and wipes Royal Straight Slasher off the field with that attack, Fiendish Chain disappeared too.

Atem braces himself as his monster was gone and he lost 600 life points. "That's it." Kaiba ends his turn. Atem: 7400 LP.

"Not bad either, but I'm fair from done." Atem draws. "I activate Ancient Rules. This card allows me to summon a level 5 or above monster straight from my hand. So take now to the field, my most trusted friend. Dark Magician!" Dark Magician appears with a boom. It was dressed in all its glory.

"Kaiba, this duel has just begun." Indeed it has.

"That's what I wanted..." And so he did. Their signature monsters stared each other down, as did their owners.

Atem: 7400 LP

Kaiba: 8000 LP

Chapter 1 is done, I'd like feedback, the more the better.
