"I suppose I should thank you for helping to provide the final piece I needed to revive the Great Leviathan." Dartz's voice called. "As thanks, you will be the first to witness its power."

"Dartz, where are you?" Yami questioned. "What's going on?"

"I don't know, but I have a bad feeling we're about to find out."

Yami's eyes widened in shock. "Yugi, but how are you…"

"When you beat Dartz, I knew you would be able to pull it off partner." Yugi smiled before turning to the Great Leviathan.

"Huh, what's that on its head?" Leo asked suddenly. "Is that some kind of tiny horn?"

"A horn?" Jack questioned before looking at the Great Leviathan just as the marks of the Crimson Dragon began glowing intensely and the Crimson Dragon appeared above them.

"What?" Dartz questioned in shock. "How is this possible?"

The Crimson Dragon just roared before The Fang of Critias, The Eye of Timeus, and the Claw of Hermos all appeared and began glowing as they slowly transformed into knights.

"Finally, after ten millennia in captivity we've been set free!" called one of the Knights.

"What in the world?" Kaiba questioned before the three knights landed in front of him, Joey, and Yami.

"This dragon has restored us to our true forms." the knight in blue armor stated. "I am sir Critias."

"Indeed, and now with his aid we shall finish what we began millennia ago and destroy this creature." the knight in red armor agreed.

"In the name of Atlantis, we will finish what we began all those years ago." the knight in green armor finished.

"In the name of Atlantis, we will destroy you!" they called together.

"Who… who are you three?" Sky asked in shock.

Hearing that the knights turned to her only to notice the marks of the Crimson Dragon.

"Forgive us madam, we are the Knights of Atlantis. I am Sir Hermos." the knight in red armor answered.

"I am known as Sir Critias." the knight in blue armor stated.

"And my name is Sir Timeus." the knight in green armor with a scar over his right eye stated. "It is thanks to the creature above you we have returned."

"The Crimson Dragon?" Jack questioned looking at the familiar monster.

The Crimson Dragon glared at Dartz before roaring only to turn to the Signers.

"My thanks, you saved my life." the Crimson Dragon told them. "The moment those corrupt dragons were formed my strength was trapped by the Orichalcos… destroying Orichalcos God Ribaisan broke that seal and allowed me to free the other souls trapped within its power."

"Other… you mean the Knights of Atlantis?" Akiza asked in realization.

"That's correct, they were nearly successful in destroying Dartz and the Great Leviathan long ago but the Orichalcos limited their strength." the Crimson Dragon explained. "They are the ones who can send you all home as they called you to this time in the first place."

The Signers, Sky, and Angel all stared at the three Knights of Atlantis in shock hearing that.

"The threat of the Orichalcos was too great, we used a great deal of our power to call for aid in whatever form we could. Your dragon answered our call but in doing so it drew the attention of Dartz and for that we apologize." Critias explained.

"We can worry about that after we deal with this thing, any ideas?" Yusei inquired.

"Do you even need to ask Yusei?" Jack questioned. "We bring out our dragons and destroy that thing."

"Your dragons are of no threat." Dartz stated. "I will destroy all of them and finish what I began millennia ago!"

"Dartz, you're wrong." Yami stated. "Come forth, Valkyrion the Magna Warrior, Black Luster Soldier, Shadow Sorcerer, and Dark Magician!"

"You're right Yugi, help him out Red-Eyes Black Dragon, Gilford the Lightning, and Flame Swordsman, and Inferno Samurai!" Joey called.

"I call on the Blue-Eyes Ultimate Dragon, XYZ Dragon Cannon, and my Gadget Soldier!" Kaiba declared.

"Kaiba, take this." Yami told him throwing Kaiba a card.

Kaiba's eyes widened seeing the monster before he smirked. "Come forth, Blue-Eyes Maiden!"

"Guess that makes it our turn." Angel smiled holding up a card. "I summon Daigusto Tornado Dragon!"

"Celestial-Dragon Quasar come forth." Sky declared.

"Protect us, Ancient Fairy Dragon!" Luna cried.

"Come forth, Life Stream Dragon!" Leo called.

"Join the fight, Black-Winged Dragon!" Crow called.

"I summon Black Rose Dragon!" Akiza stated.

"Time to end this, Red Dragon Archfiend!" Jack called.

"The Orichalcos and the Great Leviathan are too dangerous to ignore, we need to destroy him." Yusei mentioned. "Take flight Stardust Dragon!"

With that the group of monsters appeared to oppose Dartz and the Great Leviathan.

"Summon whatever creatures you want; it won't be enough to defeat the Great Leviathan." Dartz smirked.

"Dartz, you're wrong." Yami stated. "We will take you down."

"Couldn't have said it better myself." Yusei mentioned. "You guys ready?"

"Do you even need to ask Yusei?" Sky inquired with a smile.

"Attack!" the eleven of them called together as their army of monsters flew towards the Great Leviathan and tried to attack it with a massive attack only for the Great Leviathan to roar and destroy nearly all of the monsters leaving only the three knights and the Synchro Dragons.

"A pitiful attack, your monsters are mere insects compared to the overwhelming power of the Great Leviathan." Dartz stated only to pause. "What, how did those dragons survive?"

"These dragons are more powerful than you realize. They will not fall in this battle and neither will we." Timeus declared.

"Alright, this is it you guys. We need to take him down, and I just might have an idea how." Yusei mentioned. "Four monsters attacking at one time."

"Four monsters?" Leo asked before his eyes widened. "Wait, do you really think that would work?"

"There's only one way to find out Leo, and it's our best shot of taking this thing down." Sky replied as the Great Leviathan roared again.

(The Signers, Sky, Angel, Yami, Joey, and Kaiba have started fighting against the Great Leviathan and Dartz alongside three knights from Atlantis but so far, they haven't done any damage. Next chapter the battle will continue. As always any reviews or critique is appreciated.)
