Jaune's "Uncle" Mordred comes to help with some training in her-Ahem, HIS own way...


Team JNPR and Team RWBY were returning from a joint training mission. They walked through Beacon's Star Maiden garden, which filled with beautiful fountains, flowers, and marble columns.

"Geez, after that training mission, this boring place is just what the doctor ordered!" Yang sighed happily.

"I will admit, serenity is very nice after dealing with all those issues," Ren sighed.

"Aw, it was fun!" Nora protested with a grin as she hefted up her hammer. "I got to smash those Grimm right in their stupid faces!"

"Along with the chicken coop behind it," Jaune sighed, brushing off some leftover feathers. Ruby grimaced.

"That was the worst!" She groaned. "We should be-be fighting super awesome evil Grimm and saving kingdoms and-and handsome princes or something!"

"Or handsome knights," Yang said with a wink at Jaune. Jaune coughed as his cheeks burned red. Ruby scowled.

"Yaaang! Enough flirting!"

"Did you want to get some flirting in, too?" Yang grinned. "Maybe we should make a sign up sheet!"

"Ease up, guys," Jaune sighed, "I want a shower."

"Yes, please," Pyrrha cleared her throat, brushing some feathers out of her red hair, "A shower would be nice."

Yang sighed and brushed some stray feathers from her jacket.

"Fine, fine."

"Honestly," Weiss sighed, still scrubbing her hands with antiseptic gel, "I had no idea chickens were so disagreeable!"

"This is why I prefer fish," Blake said. "Also, do you always carry antiseptic gel?"

"Yes. Why, don't you?" Weiss asked curiously.

This is when loud music began to play over the courtyard speakers. Jaune paled as he heard it.

"What is that song? It sounds super old! 'Bye bye bye?'" Ruby exclaimed.

"I think Dad used to play it all the time... VB?" Yang added, noticing how Jaune tensed.

"Jaune?" Pyrrha asked, staring at Jaune's reaction as he pulled his weapons out.

"ARM YOURSELVES! NOW!" Jaune shouted.

"Are you kidding-?!" Weiss tried, even as everyone else obeyed. Just in time, too.

A figure in heavy combat armor, with curved horns on her helmet, charged in and swung her sword at Jaune. Jaune barely parried the first three blows, before the figure sidestepped his desperate counter attack and slapped him on the ass with the flat of her blade. This sent him flying headfirst through a stone bench, his Aura flaring brightly. Everyone else scattered, Pyrrha, Ren and Nora regrouping immediately.

"JAUNE!" Ruby however was the first to strike back. She leaped into super speed with her Semblance, and struck the armored figure several times. Each time the figure parried or deflected the hits with her sword, before yanking Ruby into range, punching her in the stomach, and throwing her into a column.

"URK!" Ruby gasped.

"A Lancer who gets too close and fights too predictably..." The Figure commented while blocking Pyrrha's furious counter strikes and then evading Yang's berserker rage. "Hmmm..."

She traded sword blows with Pyrrha while evading everyone else's fire. Yang then charged at her, her eyes glowing red and her Aura burning like fire.

She caught Yang's wrist and threw her into Pyrrha. Pyrrha tried to catch Yang... Which is when the figure closed the distance and slapped them both into a fountain with her sword. They smashed through the marble fountain and fell into the pool with a large splash.

"A Berserker without brains or agility and another Lancer who is far too showy and emotionally compromised-" She dodged around Nora's wild swings and slams, using her agility to disarm the hammer maiden and then kick her into a tree.

"Another Berserker who is too wild-"

Ren popped up from behind a stone bench and tried to strike her from behind, but the figure swung around and unleashed an Aura blast that sent him crashing through a statue.

"Assassin with shitty weapons-" She casually backhanded Weiss who tried to charge her. Weiss plowed into a flower garden with a screech.

"A Caster who thinks she's a Saber-"

She looks over at Blake, who was hesitating on top of a pillar. She swung her blade and unleashed an Aura blast. Blake used a clone to avoid it, sent two more in… Who the figure plowed through to backhand Blake into the recovering Yang, sending both back into the fountain pool.

"EEYAH!"

"And finally, another Assassin who thinks too much." She sighs, "JAUNE! Your teams are very disappointing!"

Pyrrha got up and attacked again. This time the figure was forced to fight a bit more seriously, having to parry and counter and even evade Pyrrha's furious assault. Pyrrha managed to get a hit on her helmet, cutting off the tip of her horn. The figure traps Pyrrha's blade against hers.

"Ooh... I may have misjudged you. You might be fun-" the Figure said, a feral grin in her voice.

At last, Jaune got up and yelled a threat.

"DAMNIT MORDRED! STOP IT RIGHT NOW OR I'M CALLING NANA!"

Mordred gasped and turned her head to look at Jaune.

"YOU WOULDN'T!"

Jaune held up his Scroll. Mordred huffed, and pulled back from the panting Pyrrha. The rest of RWBY and JNPR got up. Ren was slightly tense. Nora was curious. Ruby was scowling. Yang and Weiss were glaring hot death at Mordred, and then at Blake.

"You SAID you were gonna back me up!" Weiss accuses.

"Well, I-!" Blake tried to defend herself.

"I thought you were gonna do the same!" Yang interjected.

"Would it have actually mattered?! We all got clobbered!" Blake retorted.

"YES! YES IT WOULD! WHO THE HELL ARE YOU AND WHY DID YOU ATTACK?!" Ruby demanded.

The woman's helmet slid open with mecha-shift technology, revealing a rather strikingly beautiful older blonde woman with blue eyes, a ponytail for her slightly white streaked locks, and a cocky grin.

"I am Sir Mordred Arc! Knight of the Round Table! Heir to the throne of Albion! And... Jaune Arc's great-uncle." Mordred declared.

"WHAT?!" Weiss cried.

"Wha-You're Jaune's unc-but you're a-!" Ruby stammered, but Jaune held up a hand.

"DON'T! Don't! It's not worth it! Just call her-um, him, Uncle Mordred." Jaune sighed.

"Did you really have to attack us as a greeting?! Are you insane?!" Weiss demanded, shaking her fist.

"YES! It is how one should properly greet Hunters-in-Training! And given I mopped the floor with you all except the redheaded Lancer, you clearly need a lot of work! Jaune I can understand-His parents forbade him from training and he is catching up! But YOU! How the mighty have fallen!" Mordred exclaimed, standing at attention with her blade held downwards between her hands.

"Mordred, you are literally 80 years old and have seen more combat in a week than most of us have in a lifetime." Jaune pointed out, exasperated.

"BIG DEAL! If you'd worked together you might have stood a chance! Well, nothing for it! I shall have to train you myself!" Mordred declared.

"Oh wow... Jaune? Your uncle is cool and super hot!" Nora expressed in awe. Ren raised an eyebrow.

"DAMN RIGHT I AM!" Mordred boasted.

"She's a lunatic-" Weiss started to say before Mordred held a sword to her throat, "Urk!"

"Don't call me a woman, damnit! Just because I have a husband and have borne him children does not MAKE ME A WOMAN! It merely makes me very manly!" Mordred clarified.

"I-You-!" Weiss stuttered. Jaune again reached out and pulled Weiss away. He shook his head.

"Please. Don't. You'll only make things worse." Jaune warned. Weiss sucked in a breath and slowly nodded.

"S-Sure, um, Mordred. You are... Very manly." Weiss reluctantly acknowledged.

Mordred withdrew her sword, "EXCELLENT! Now, all is not lost! You have promise! But back in MY DAY, we were fighting bandits and Grimm beasts every single day for classes! None of this cushy boarding school nonsense! We shall go get alcohol-!"

"AHEM. Underaged? Ahem?" Jaune coughed.

"In Vale?!" Mordred demanded. Jaune nodded sadly. "DAMNIT! FINE! We shall go get drinks of some sort! And then perhaps get our nails done! I like the star designs on my nails, that's extra manly!"

"I like stars on my nails too!" Ruby said cheerfully. "I just learned how to do them!"

"WONDERFUL!" Modred declared with a grin.

Nora held up her hand.

"Question!"

"Yes?" Mordred responded.

"Why that old music?" Nora asked.

Mordred huffed.

"It's catchy and I enjoy listening to music while training!"

Nora gasped, her eyes bright.

"IT IS SUPER CATCHY! Right Renny?"

"The catchiest," Ren agreed in his usual deadpan.

"Why can't there be a normal Arc?" Weiss muttered. Blake grumbled in agreement.

Jaune looked over at Pyrrha, who was looking very intensely at Mordred.

"Pyrrha? You okay?"

Pyrrha turned to Jaune. Her eyes were sparkling, "That was the most intense fight I've ever had, Jaune! I can't wait for your uncle to train us more!"

Jaune sighed. He wore a wry smile.

"Yeah, me too..."


Naturally, if Arturia Pendragon is Jaune's great-grandmother, then Mordred is his great-uncle... Sort of. She's actually Shirou and Arturia's biological daughter in this timeline but Morgana le Fay still pulled some crap to get revenge on Arturia. Mordred was saved, is still loyal to her "father" and "mother" but uh... Has some issues. She did end up marrying a man and having kids though, so she got a happy ending too.

And naturally she kicks all their asses to N'SYNC's "Bye Bye Bye". Because hey. I liked Deadpool and Wolverine.
