Team RWBY and PNR just stood there in shock, this guy just slaughtered a huge group of White Fang, wounded Roman Torchwick, and made the Paladin unmoveable. He dropped his clips and reloaded then holstered his guns. He was armed with a pair of Glock 18s in reach around holsters, and a pair of Colt .45 calibers under his arms. He was holding a pair of M1911s. All of them were either white and gold, or black and gold. The right ones in black and gold, and the left is white and gold. He also had a guardless ninjato with a black, white, and gold handle.
He was dressed in a white breastplate with a gold and black double crescent moon with the points up on his chest, the top one in gold and the bottom in black, black cargo pants and boots, a white and gold shooter glove on his right hand and a black and gold shooter glove on his left. To finish the look, he had on a gold helmet with white eye holes.
"Well," he said as he twirled his right gun and holstered both down his thighs. "That was easy." They looked at him, Blake had stormed up to him.
"HOW COULD YOU? THEY WERE INNOCENT!" She yelled.
"Man, you sure do believe the crap Taurus fed huh Belladonna?" She was shocked he knew her, "Surprised I know you? You and the Fang are nothing but a waste of space, just like how you thought Arc was!" Did he know Jaune? Just then, Weiss spoke up.
"You knew that dolt?" She said.
"Just like I know your dipshit of a father." He said, "Oh sorry. I mean, knew your dipshit of a DEAD father." Weiss was furious and drew her rapier, "Oh what are you going to do? Kill me like you did him? All because you don't like me? Because I killed your father?" She froze, "Come on Schnee!" He drew his ninjato, "Let's get nuts!" Weiss looked at the blade crossed against hers. Knowing that she couldn't beat him, backed down. Then he put his sword away, "Cowards. All of you!" He glared at them, and Pyrrha spoke up.
"But who are you," she asked. "Maybe if we knew who you are, we could figure out what's your problem with us." He looked at the Mystral champion like she was stupid.
"You don't know who I am?" He said, "The one person, who isn't cut out to be a hunter? The one who would get your little girlfriend killed Lie? Maybe, I'm someone who would make Rose hate you, Xiao Long? Or I'm a dolt, Schnee?" The others looked in shock, he couldn't be. He pushed a few buttons on his helmet and it opened up revealing he had blond hair with white bangs and blue eyes with so much hate for them in them with a scar over the right one. They paled, "Surprise." He sang, it was Jaune Arc.
Note: This is something I came up with where Jaune is a Red Hood-like character after being betrayed by his friends. Weiss kills him while Cardin has his attention after saving him from an Ursa Major. Plus, I wanted to see what you thought about this.
