The prompt for this was "In a surprising twist, Jaune actually manages to strike down and kill Cinder after she killed Amber and absorbed the Fall Maiden's power."
Golden light flowed from Amber into Cinder. Fire danced around the dark-haired woman, and her eyes began to glow. Jaune rushed towards her without hesitating, sword raised.
"Stay back!" called Ozpin, but it was too late. With a casual flick of the wrist, Cinder sent Jaune crashing into the wall beside her, leaving cracks in the column he had struck. Pyrrha pounded on the glass of her pod, screaming his name.
Cinder took a step towards Ozpin, a smug smile on her face. She stopped when an enormous groaning sound filled the hall.
Cinder looked up to see the column that she had thrown Jaune into was collapsing on top of her. She raised a hand and summoned the maiden's power to knock the massive piece of stone away from her. It landed behind her with a earth-shaking crash.
Before the dust had finished settling, Jaune was on his feet and charging Cinder again. She snarled at his insolence and slapped him aside with the full power of the Fall Maiden. Jaune went sailing into the opposite wall, crashing straight through a column.
Cinder shook her head. "Now that that's out of the way..." She turned her gaze to Ozpin who was staring in disbelief. She smirked until she realized that he wasn't staring at her.
Cinder followed the headmaster's gaze in time to see the column that Jaune had crashed through was now falling on top of her. She raised her hand and unleashed a blast of fire, melting the stone just in time to save herself from being crushed. As the molten rock splashed around her, Cinder's annoyed expression finally turned to rage.
"ANYTHING ELSE?" she howled. She waited a moment, and when there was no answer, she took another step towards Ozpin.
That was when the part of the ceiling that the two columns had supported gave way, sending hundreds of tons of rock raining down on Cinder. She was buried before she ever had a chance to react. A golden light emerged from the pile of rubble before dissipating into the air.
Pyrrha finally freed herself from the pod and ran past Ozpin, who was staring at the rubble in disbelief. She ran to Jaune's side, who was still picking himself up from where Cinder had knocked him. After checking to make sure he was alright, she spoke.
"I can't believe how lucky-"
"It wasn't luck," interrupted Jaune. "I did that on purpose."
Pyrrha opened her mouth to speak, but Jaune cut her off again.
"Next you'll say 'That's impossible, Jaune, you'd have to be able to see the future.'"
"That's impossible, Jaune, you'd have to be able to see the future," said Pyrrha. Then she gasped in surprise. She and Ozpin stared at Jaune for a long time, mouths hanging open.
His Semblance... It can't be.
Finally, they recovered enough to speak again.
"What happened to the Maiden's power?" asked Pyrrha.
"Her last thoughts were of Jaune, or possibly of me. The power went to seek out a random host." He looked from one student to the other. "That was absolutely amazing, Jaune. But with the Maiden's power potentially on the other side of Remnant, we're going to have our work cut out for us defending the school."
Pyrrha turned her head from Ozpin to Jaune, who looked about as good as someone who had been hurled through two stone columns (three actually, but the other had been hours ago) possibly could.
"You're right, Professor, but somehow I can't bring myself to be worried right now." In spite of himself, Ozpin nodded in agreement.
The professor and his two students began heading back towards the elevator, feeling like even the Grimm dragon that waited for them outside was nothing they weren't ready for.
I had several ideas for this one, but most of them just felt like generic "Jaune is OP" fics, or else made Cinder look like a complete joke. I didn't want to go either of those directions, so I focused on the image of Jaune getting thrown into a wall and went from there. I thought about having it be a genuine accident, but I was too tempted by the Jojo reference. And after all, Joseph was the king of bullshit, so Jaune might have been bluffing about planning what happened to Cinder...
