Gilgamesh in DxD

"Hahahaha that's right." said Achilles as he didn't look much different.

Gilgamesh who was staring amused gave a cough on his hand to get their attention.

"So I want to know what you guys chose?" asked Gilgamesh seriously.

He had given Achilles and Merlin the same choice he had given Arturia, if they wanted they could return to the Throne of Heroes. Gilgamesh would not force them to serve him.

But Achilles burst out laughing

"Are you kidding, master?" questioned Achilles with a huge grin, "A world where the Age of the Gods never ended and with several powerful opponents to test yourself against?! I couldn't have chosen a better master to summon me" said Achilles with a huge smile.

Right after that the Hero of the Trojan War slammed his spear into the ground.

"I, Achilles, son of the great hero Peleus and the goddess Thetis, in the name of my father, mother and friends will serve you as your servant and exterminate all in your path" said Achilles with such honor and joy that even Gilgamesh and his friends were surprised, including Karna.6

Gilgamesh smiled at this and turned his attention to Merlin who was smiling.

"Well even if my lovely ward didn't give a lovely welcome to me" said Merlin dramatically as tears streamed from his eyes and he took a handkerchief from God knows where to wipe them away.

Everyone especially Arturia smiled at that.

"Good to see you Merlin" said Arturia smiling at the mage.

Merlin's tears quickly disappeared as a huge smile broke out and he turned his gaze to Mordred who stared at him bored.

"Old pervert" said Mordred causing a small storm cloud to arise above Merlin as he muttered that he was not an old pervert.

Gilgamesh smiling gave a cough to get the attention of Merlin who quickly stood up with a cheerful look on his face.

"Of course this great mage will serve you, my master as he once served the great King Arthur" Merlin said as he puffed out his chest with pride.

Everyone couldn't help but smile at that.

Gilgamesh and everyone else began to laugh as Merlin began to brag about how well he would serve as well as he did for Arturia.

There was no doubt that with these two everything would be more fun for Gilgamesh and his friends.

Some Time Later.

On a vast plain was an immense expanse of green grass totally lush with several mountains in the background and trees all around.

In the middle of this immense battlefield created by the system being a dungeon had two people on opposite sides.

On one side was a tall man about six feet tall having golden hair down to his neck and two deep slit crimson eyes.

He was Gilgamesh, the King of Heroes and the first hero of the world.

From the other was a tall man with spiky green hair that stands upright except for a single fringe that falls over the left side of his face. The chest piece of his silver armor also features a bird. An orange cloth is loosely wrapped around his body.

Although his face is pleasing to the eye, he is not like the knights of old, whose courtesy softened the hearts of noble ladies. He has the eyes of a raptor, a strong and firm constitution, and the absence of any appearance of rudeness.

This was Achilles one of the famous heroes of the Trojan War, the demigod son of the sea goddess Thetis and the mortal hero Peleus.

Soon after Achilles and Merlin were summoned, the Great Hero of the Trojan War challenged Gilgamesh to a battle because he wanted to know the level of his master's strength.

Gilgamesh saw no reason to refuse the battle and agreed, so they all agreed to go into the dungeon.

Further away from the battlefield were all the spectators, Enkidu, Sebas, Valerie, Tiamat, Fenrir, Mordred, Arturia, Asia, Arthur, Le Fay, Karna, Leonardo and Merlin who were watching the battle intently.

"Are you ready master?" asked Achilles with an immense smile.

Even though he had not fought or seen any of Gilgamesh's power the Hero of the Trojan War knew very well that the King of Heroes was immensely powerful, not only because of his connection to the Throne of Heroes.

Gilgamesh's very presence screamed power, his very presence emanated an aura so overwhelming that Achilles could not even comprehend it, an aura that made even the Gods of Olympus pale in comparison.

An immense smile threatened to split the face of the Greek hero who couldn't wait for the fight he would have with Gilgamesh.

"Whenever you want" said Gilgamesh as he took his hands out of his pockets and a golden aura took over his body.

"Come on" shouted Achilles as he summoned his Heroes' killing spear [Diatrekhōn Astēr Lonkhē].

In an instant Achilles firmed his feet on the ground and fired as an immense shockwave was sent out by the pressure of his shot.

Achilles advanced at an almost instantaneous speed as he broke the sound barrier and in an instant was in front of Gilgamesh.

The King of Heroes could only widen his eyes when Achilles appeared in front of him with his spear inches from Gilgamesh's face.

Gilgamesh in a quick show of skill activated his [Sharingan] and dodged by a hair's breadth Achilles' spear and delivered a strong kick to the stomach of the Hero of the Trojan War who spat blood and was sent flying into a mountain.

Achilles quickly emerged from the mountain with a huge smile on his face as he swung his spear.

Gilgamesh can only stare in surprise, for if it were not for his reflexes and instincts he would have lost his head.

In his legend, Achilles is recorded as the fastest hero in human history. This is embodied in his [Dromeus Komētēs] a continuously active Noble Phantasm. He can run across a giant battlefield in one breath and the obstacles on the field will not slow him down. Although he must expose his weak point, his Achilles heel, there are few Heroic Spirits that could catch up with his speed.

Achilles is revered as the fastest hero among all mankind, praised for his great bravery and dexterity in the Trojan War. Being equated with instantaneous movement, he is able to strike anything that enters his field of vision, as he can shorten the distance instantly. His speed is so overwhelming that few heroic spirits can keep up with him, even if an enemy can see through all his attacks, they are unable to completely avoid or block all his attacks.

"Impressive you reacted master, let's keep going!" shouted Achillea in delight as he fired again.

Gilgamesh quickly summoned a spear and fired at Achilles crashing into him and engaging in an immense battle of unparalleled speed and technique.

Their spears brandished at divine speed splitting the air and shattering all the earth they passed through, their unparalleled speeds causing them both to become blurs as they collided.

One of Achilles' well-known fighting styles is the "poison snake," an effective style for repelling enemy attacks while striking with rapid strokes, using jab and strike techniques along with clever finesse to overwhelm his opponent with his divine speed.
