An: Hello and welcome back to another one-shot for my realm of Dream. Here is another crossover which is non-KR, but making them awesome match.
I don't own both Gridman and RWBY as I writing this for fun!
Gridman: Jaune's Yume No Hero
"Hmm, so it's foolish bravery that brought you here then?" questioned Cinder as she raised her hand and created a small flame, "Well then, perhaps I'll show you just how helpless the situation is."
Cinder was about to order the Grimm to attack the docks when Jaune gave a shout and attacked. Cinder easily dodged it, but Jaune's plan had worked. He was stalling Cinder as long as possible to allow more time for everyone.
"Fine, I'll oblige your wishes," grinned Cinder as she created a ball of fire, "It'll be good to test out the limits of my power on such a willing punching bag!"
The fireball shot forward, to which Jaune quickly put up his shield to block it. He could feel the heat scorching his skin, but his Aura managed to help block out most of the heat.
"Hoo, it looks like you have a rather large Aura reserve," complimented Cinder, "Too bad all that power won't do you any good if you don't know how to even wield it properly."
Cinder fired three more fireball, forcing Jaune to skid back and try to shake off the impacts before his instincts screamed at him to move. He dove sideways just in time to dodge two arrows hitting vital organs, but not fast enough as it did hit him. One was deflected off his Aura while the other one penetrated through and into his thigh.
Jaune roared in pain as he turned to Cinder and slashed with his sword, but Cinder scoffed as she used her left hand to block all attacks without even seemingly trying.
"Pathetic," yawned Cinder as she dodged a horizontal slash while forming a dust dagger and stabbing him in the forearm, "You're not really worth even using my power." She blasted him away for a stream of fire into his chest.
Jaune stood back up in defiance as he charged once more. Cinder, getting bored, shot a stream of fire at Jaune. Jaune charged forward with his shield up, his Aura flashing through before he reached her and slashed down at her face. Cinder caught the blade with just one hand and sneered, about to taunt Jaune when she had to lean back to avoid Jaune shield bashing her.
"So you tried something different, so what?" taunted Cinder as she kicked Jaune on the chin while backflipped, taking his sword from him.
Jaune rubbed his chin in pain before noticing his sword was gone. He looked at Cinder, who held it blade side and heated up her hands. The blade began to glow under her hand until it cracked in half. Jaune almost lost heart at the sight of Crocea Mors broken.
"Looking for this?" giggled Cinder as she held the sword out, "I hope you don't mind, it broke when I held it."
Cinder tossed the blade end out of the window while tossing the handle towards Jaune.
"Oh dear, what will you do now? Perhaps run away? Or maybe you could fetch your partner and sacrifice her to save your own worthless life."
Jaune responded by hurling his shield like a disc at Cinder, to which she deflected it out of the window.
In retrospect, Jaune mused, that wasn't the best course of action to respond, but when Cinder threatened Pyrrha's life, he instinctively responded by hurling his shield like Pyrrha did to shut her up.
"Well, well, that wasn't very smart, was it foolish knight?" cackled Cinder as she looked at the completely helpless boy now, "I grow bored of this conflict. What say I finish this up and send the Grimm to your precious friends?"
This made Jaune sweat.
"So weak, I was hoping for more of a challenge," continued Cinder, "Then again, nobody stop my mistress could ever hope to match me."
"Even if it seems impossible… I won't give up till the very end!" shouted from Jaune with unexpected brave expression, causing Cinder to pause before giving Jaune a baleful glare. "Not when there are people I'm willing to protect till the end!" he continued with defiant expression.
"And what can do that for you when compared to this!" Cinder growled as she tossed several fireballs at Jaune, who jumped out of the way, "I, Cinder Fall, who have killed Ozpin! I, who have brought the Kingdom of Vale down to its knees! I, who have outwitted both Ozpin and Ironwood and their pitiful attempts at a defense! I, who manipulated the White Fang to attack and draw attention from my true goal, the Fall Maiden's powers. I, who with a simple gesture, have turned the citizens of Vale against their own protectors without even know I had the pawn, Mercury Black, fake his injury while tricking Yang Xiao Long into thinking she was being attacked!"
She soon drawn a large arrow of fire which will be impossible for Jaune to even escape from and firing at him. Just when the Grim Dragon and Cinder about to watching Jaune perished in the process before an bright orb of light from out of nowhere and blocked the attack for Jaune. As everything turn blind for everyone in the room.
Soon Jaune find himself in a blank dimension as he felt everything around him began to slow down. It wasn't long until the glowing orb appeared right in front of him.
"It's been a long time, Jaune." The orb of light replied as Jaune's eyes wide in shock.
"Sigma… is that really you?" Jaune asked, slowly and surprised.
"Yes. I heard your voice and sense your distress as I come to help you again." The bright orb of light replied.
"I… I never thought that I get to see you again," Jaune sniffed with tears down while stares at the glowing orb of light.
"Don't worry, Jaune. No matter what, we're partners to the end." The bright orb of light said. "Let's face this evil together like old time…"
After wiping away his tears, he nodded to the beam of light. Soon the orb of light circled around and attached to his right arm as a device that wasn't there before was revealed.
It wasn't long until time resume itself as Cinder was wondering what that light show was about. Soon Jaune got up as he looks at the familiar device on his wrist and smile nostalgic.
"What in the world was that?" Cinder growls.
"Let's do it…!" Jaune said serious. "Access…" he held up his wrist with the device and slammed his left hand on the golden button, "Flash!" he called as he raising his hand with the device into the air.
Soon Jaune was surrounded by a bright light that continued enlarged itself before taking up the entire space of former Ozpin's office and beyond.

Back at the docks, the last survivors were going up on the Bullheads when they all witnessed something shocking as the Grim Dragon fell from the tallest tower with a bright light following down. The light died down as it revealed to be a titan like humanoid who was the same size as the Grim Dragon appeared in middle of the city.
He was a blue being garbed in a silver chest plate, with red gauntlets and graves. There are silver shoulder plates that covered over red shoulders. The helmet resembled that of a knight, it has red marks and blue crystal on the top and two yellow eyes.
This is Gridman Sigma.
Those who were looking at the giant with surprised expression. Even though of Ruby, Pyrrha, and Weiss when they were surprised to see massive giant before them as they originally tried to reach for Jaune.
The Grimm Dragon roared at the new challenger and dived toward him. Gridman Sigma sidesteps to the right and grabbed the Grimm by its tail before swing it over his shoulder. This caused the Grimm Dragon to fall straight to the floor, causing an earthquake. Gridman Sigma soon slammed his fist into the Grim Dragon multiply time. The Grimm Dragon screeched in pain as gallons of ooze fell out from its wounds. The Grimm Dragon spat out fire from its mouth at the giant, forcing Gridman Sigma to let it go.
"Sigma Slash!" Gridman Sigma shouts as a blade of light generated from his left hand and he tossed the blade of light as a boomerang to slice the Grimm Dragon of its wings, causing the Elder Grimm to roar further in pain.
Sigma… Once I restore the communication line, I need you to sending that 'record' in my scroll to everyone and tell them to spread them! Gridman Sigma thought before the crystal on his chest glow.
'Roger that!'
Soon Gridman Sigma spread his hands across the city as gold sparkles flow across the city and other area as every scroll become activated with unexpected footage that will shocked them. Especially some of them recognized the sender was from Jaune but no one know what happened to the blonde knight.
With that done, Gridman Sigma soon raised his right arm to face against the Grimm Dragon.
"Time to finish this… Grid Sigma Beam!" Gridman Sigma roared serious as a powerful beam shot from his right arm and struck the Grimm Dragon in the process.
Its struggled to resist the attack, but it was futile for the Elder Grimm before it was destroyed by Gridman Sigma's attack. The sight of the Elder Grimm being crushed by the giant made those Grimms who tried to invade, decide to retreat ensure that they won't suffer the same fate.
(OST End)
Soon Gridman Sigma felt slight burn from his right side and saw Cinder who was standing on top of a building, trying to attack him with her fire arrows. But Gridman Sigma didn't say anything as he slammed his fist on top of where Cinder was, causing the building collapsed from his fist. Soon the giant released his fist to see Cinder still alive, but barely moving and choked on her blood.
"Y-You can't beat me… I have the power of Fall Maiden!" Cinder growls defiant at the giant. This made Gridman Sigma frown before slammed his fist on Cinder once again and seeing Cinder barely alive.
"You will never harm Pyrrha or anyone else again…!" Gridman Sigma growl before grabbing Cinder with his right hand.
He then looked up at the sky and tossed her far away as Cinder Fall will only be seen as a shooting star in the sky.
To be continued…
AN: That is what I have for my first Gridman crossover one-shot. I choose Gridman Sigma since he looks more like a knight to match with Jaune. Some parts of here is inspired by Jaune of Keyblade by azndrgn. Anyway, be sure to review or message me for any questions, comments, or concern. And don't be afraid to look at my other stories.
