Jaune Arc listened to Pyrrha's chant as she awoke his aura. His eyes widened as he connected to something. Information flashed through his mind of a throne, a storage device for heroes. One stood above them all though, and almost instinctively, he reached for that shining light of heroism.
Gilgamesh noticed the thing trying to reach him, and scoffed at the fool. The moment he brushed the King of Heroes, he was to be destroyed. However, it had been a few million years since he walked his garden. The boy had spirit, so the king would reward him, by using him to return.
Pyrrha closed her eyes as Jaune gave a golden glow, and widend she looked back, the boy she had met looked down with blood red eyes. "Jaune?" She asked.
For a moment, Gilgamesh ignored her, as he processed the remnant of a world he was now in, and the revelation that he now had the morals of a wanna be knight. He debated whether or not to quash the last remnant of the human, but ultimately came to a decision based on his good mood, and the remembrance of Saber. So his decision was made. He would King Arthur this life, and do it better than she did, just so that when they met again he could say he did it better. That meant he would have to interact with this mongrel mostly congenially, though. He sighed. "Sorry, my semblance just overwhelmed me. Let's look for the relics." And he wandered in a random direction. Pyrrha worriedly followed the now golden armored Jaune.
They quickly found the relics, and Gilgamesh tossed them all in his Gate of Babylon, shocking Pyrhha as he tosses most of them back out. "My semblance allows me to create a portal to my own personal treasury." He explained out his ass. "I put them all in because, as finder, they all belong to me, and I can now return them to my vault at will."
She nodded, her head and quickly asked, "How did you know it activated?"
"How am I supposed to know?" He rhetorically asked.
At this time, Yang and Blake came out of the wood line, "Hey guys!" Yang says cheerfully as she walks up and picks up a pony. She looks over to the golden armored and red eyed Jaune and says, "Hey, what happened to you, Vomit Boy?"
Now, Gilgamesh still had the moral code of Jaune, this is the only reason why the next scene does not turn this into a nsfw retelling of Gilgamesh's pre-Ekidu tyrant phase on Yang. Instead, the arrogant king looks at the blonde brawler and says, "You will not call me that, mongrel. If you so much as think of saying, I will shave your precious hair in front of the entire school."
This of course, pissed of the blonde as she immediately whent rage mode and tried to punch Gilgamesh. He instead backhanded her into the ground, put his golden boot on her chest, and said, "You are lucky I am feeling merciful, mongrel." He growls as he pulls her up by her hair and tosses her into an incoming Nevermore. Ruby Rose and Weiss Schnee fell in the chaos as their ride crashed to the ground the three girls shook their heads and prepared for battle until golden portals appeared all around the Grimm, and a bunch of priceless weapons reduced the creature to nothing in the span of a split second. "We're done here." He said as he pulled out a glass of wine, and then levitated up to the cliff. He looked at Ozpin and said, "I am Gilgamesh of Uruk.
(I'm trying to think of a name for the new team, any help is appreciated.)
