A/N: Welcome to What Makes a Hero?, the crossover between RWBY and Yuki Yuna is a Hero. If you haven't seen the latter, I suggest you watch it on Netflix, so you know what's going on. Even though I'm bending the rules a lot, I hope you enjoy!


WHAT MAKES A HERO?

Chapter 1- New Heroes

"Yuna!"Fu yelled, as the Vertex batted the pink-haired girl into the ground. Slicing the enemy she was fighting in half, she ran over to her friend, who was struggling to her feet. "I'm fine, Fu. It'll take more than that to beat me!"Yuna said, smiling, before a roar from the giant Vertex drew their attention. At that moment, the rest of their team, Tougou, Itsuki and Karin, ran up. "Yuna, you okay?"Tougou asked, before Yuna nodded. "Yeah, but we need to find a way to beat that Vertex."The brawler said, as the creature roared again, and raised it's foot, preparing to bring it down on the Hero Club...


As the foot started to descend, there was suddenly a flash of steel, and the foot flew off the leg, causing the Vertex to stumble back, creating a giant dust cloud. As the Hero Club struggled to see, they managed to make out the silhouette of a hooded figure, holding a sword. As the dust cleared, they saw that the figure's hood was pitch black and shaped like a panther. The figure raised the sword, and pointed it at the Vertex. A sound erupted from the sword, before a blast erupted from the tip, and a streak of light streaked towards the Vertex, striking it in the middle of the chest, sending it backwards again. The figure then raised their empty hand, and clenched it into a fist. A loud screech then erupted from the forest around them. "What was that?"Karin asked, before another hooded figure, dressed in red, and with an eagle hood, leapt out of the treetops, and halted in mid air, before shooting towards the Vertex, punching straight through it. The figure in black then leant forward, before blurring out of sight, and a pair of coloured streaks started to barrage the Vertex.

Eventually, the figure in red slowed, spun on the spot, and stabbed their sword into the ground, thus beginning the sealing ritual. As the core of the Vertex appeared, the black figure leapt up and brought their sword down, shattering the core completely. They then turned to the figure in red, who had slumped to the ground, and extended a hand, which the red figure took, and allowed themselves to be helped up. The Hero Club then walked up.

"I don't mean to be rude or anything, but who exactly are you?"Fu asked, before the figure in black looked to the one in red, who nodded. Turning to the Club, both of the figures raised an arm, where what looked like a screen was situated, with a button on one side. Raising their other hands, they pressed the button with two fingers, and a flash of light engulfed them, and when it died down, the Hero Club could see a pair of...boys standing in front of them. One was dressed in a black jacket and hoodie, t-shirt and tracksuit bottoms, and the other was dressed similarly, but in red. The two then looked to the Hero Club.

"You must be the rookies the Taisha talked about."The boy in black said, before the Hero Club looked to each other in confusion. "Who are you, and who are you calling rookies?"Karin demanded, before the boy in black chuckled. "Apologies. That was mean. I should have put it less bluntly. First, introductions. My name is Adam Robertson, and this..."he said, gesturing to the boy in red, "...is my older brother Jamie. We're Heroes, like you lot." Frowning in confusion, Fu stepped forward. "I thought only girls could turn into Heroes."she said, before Adam nodded. "You're right, only girls can usually become Heroes. But, the Taisha tried to give boys the ability to transform, via experiments. My brother and I are the only two that succeeded."he explained, before the girls gasped. "What kind of experiments?" Tougou asked, before Adam looked to Jamie, who nodded, before speaking up. "Let's put it bluntly. It was the kind that rewrites a person's DNA to enable them to transform. It hurt. A lot. And now, we're much more powerful, and act as a sort of strike team for the Taisha. Our latest orders are to assist you lot in your fight against the Vetexes."The older boy explained, before Fu nodded. "Okay, I guess we can work together."she said, extending a hand, which Adam smiled at, before he shook it. The screen on Adam's arm then beeped. Bringing his arm up, Adam's eyes widened. "There's another Vertex, coming in fast."he said, before Jamie smiled. "Great, another punching bag."he said, cracking his knuckles. "No, brother, I think that we should let this lot show us what they can do."Adam said, looking to Fu, who heaved her giant sword onto her back, and smiled. "Got it!"she said, before she turned to the Hero Club. "Let's go!"she said, before the Club nodded. "Roger!"they said, before leaping away. The brothers chuckled, then jumped up to a branch to oversee the battle.

"You sure about this, little brother?"Jamie asked, before Adam shrugged. "I'm not too sure. I mean, think about it. They've been told that only girls can become Heroes, and all of a sudden, they're introduced to two boys who can become Heroes. It'll be hard, but we need to prove they can trust us."he said, before Jamie nodded. "Sure thing, bro."he said, before the two turned their attention back to the battle going on between the Club and the Vertex...

After a few minutes, the core of the Vertex was destroyed by Karin slicing through it, and the brothers leapt down from their branch. "Not bad."Adam said, before the Club smiled. "Oh, we never told you two our names."Fu said, before Adam raised a hand to stop her. "No need. The Taisha told us who you all are."he explained, before the Club nodded. Again, Adam's arm beeped, and when he looked at it, he said, "Right, the world's going back to normal.", before looking to Fu. "The Taisha have arranged for us to join your school. We'll contact you tomorrow."he said, before the older Inubozaki girl nodded. "See you then."she said, as the white light engulfed them all...


Back in the real world...

When the light died down, it revealed that the brothers were standing in their house, dressed the same as their Hero forms, minus the animal imagery. The brothers looked to each other, before they smiled, and went over to the closet, grabbed a pair of wooden swords, and went into a dojo built into the side of the house, before standing at opposite sides of the room, facing each other. "Ready?"Adam asked, before Jamie nodded and said, "Don't hold back." Smirking, Adam replied, "Not in my nature.", before he launched himself forward, and the brother's swords clashed together...


The next day...

As Yuna and Tougou settled into their seats in the class, their teacher entered the room. After doing the usual greeting, the teacher said, "Well, students, today I've got good news. We're gaining not one, but two, new students today. They are a pair of brothers, who are transferring in from Scotland. I ask that you show them the respect they deserve as your classmates."she said, before going to the door. "You two can come in now."she said, before the two boys entered the room. They bowed, and introduced themselves to the class, before the teacher pointed to a pair of empty chairs at the back of the class, next to Yuna. "Those two seats are free."she said, before the brothers nodded and went to sit in the seats. As Yuna and Tougou looked to them, the brothers winked at them, before looking to the front of the class.


After the class ended, Yuna stepped up to Adam, and tapped him on the shoulder, gaining his attention. "Do you two need help finding your way round the school?"she asked, before the brothers nodded. "Sure. Let's go!"Adam said, before Yuna smiled. "Great!"she said, as she pulled Tougou's wheelchair out from her desk. "Follow us."she said, before the brothers nodded and followed the pair down the hall, eventually reaching the Hero Club room. After opening the door, Tougou and Yuna saluted into the room, and said, "Reporting for duty!", before entering the room, the brothers behind them. When the two boys entered, they saw that Fu, Itsuki and Karin were already present. "Ahh, Adam, Jamie, good to see you!"Fu said, before saluting. Smirking, Adam playfully said, "At ease, soldier.", causing the girl to lower her hand, smiling all the while.

"Right, so what exactly is this Club? What do you do here?"Jamie asked, before Itsuki held up a notepad. "We help out around the area, to make people's lives better."it said, before Adam nodded and looked at Itsuki. "Thanks. You're a mute?"he asked, before Itsuki looked down at the ground. "It's...complicated."Fu said from behind him. Smiling, Adam straightened back up. "Nah, I know what's going on."he said, looking round the room. "You all went Mankai, didn't you?"he asked, causing the Club to gasp. "You know about Mankai?"Fu asked, before Adam nodded. "Course I know about Mankai. Jamie and I have been doing this a lot longer than you lot. Trust me."he said, before he looked at Yuna, who was in the middle of eating her lunch. "Your file said that you love the food you're eating, but you've not shown that you can taste it, as you've not shown any delight. You lost the sense of taste."he said, before Yuna nodded, before he turned to Tougou, who had an earphone in one side. "You're listening to music, but only in one ear. Now, maybe the sound comes out better in one ear, or you're deaf in the left side. It's either that, or the fact that you're in that wheelchair. One of them's the result of Mankai, I'm guessing."he said, before Tougou nodded. Moving on, he turned to Itsuki. "You're obvious. Ability to talk, gone."he said, before he finally turned to Fu. "With that eyepatch, you're either trying to look cool, and failing miserably, or to mask the fact that your vision is gone in your left eye."he said, before Fu nodded. Looking to Karin, he said, "Count yourself lucky you didn't go Mankai. God knows what you could have lost."he said, before Yuna tapped him on the shoulder.

"How do you know so much about Mankai?"she asked, before Tougou wheeled herself up. "Is it not so obvious? He knows about it, as he's went Mankai himself."she said, before Adam nodded. "You're clever, Tougou, I'll give you that. Yes, I know what Mankai feels like. Same for my brother."he said, before Karin spoke up. "And what did you two lose?"she asked. Looking to Jamie, who nodded, Adam went over to Yuna, and gestured to the fork she was using. "May I?"he asked. Nodding, before wiping it clean, she passed the utensil to Adam. "Right, now I have to ask. Any of you squeamish? If so, look away."he said, before he raised the fork, placed his hand on the table, then drove the fork straight into it. As the Hero Club gasped, their eyes widened when he pulled it clean out, with no cries of pain. "How the...?"Fu went to ask, before Jamie cut her off. "We lost the same thing the first, and only, time we went Mankai. We lost the ability to feel pain."he said, before looking to Adam, whose hand was bleeding quite badly. As Yuna went to assist him, he smiled. "Thanks to the Taisha, we've gained a neat little trick. Watch."he said, before his hand glowed faintly. As the light died down, the Club saw that the injuries had healed, and now looked as if the incident had never happened.

"Accelerated healing. Makes us damn near impossible to kill."Adam explained, before Yuna's eyebrows furrowed in confusion. "Why didn't your fairy prevent that?"she asked, before Adam smiled again. "We don't have fairies..."he said, before he nodded to Jamie, and what looked like black fire engulfed his hand, and red done the the same for Jamie. Flinging the flames up, the brothers took a step back, before two ghostly animals landed in front of them, a black panther and a red eagle. "We have animal spirits."Adam said, before the panther turned to him. Raising a hand, he clicked his fingers, and the panther dissipated. Next to him, Jamie done the same with his eagle. "Yeah, I meant to ask. We've got flowers for our symbols, but you two have animals. How's that?"Yuna asked, before Adam looked to Jamie. "You want this one?"he asked, but his brother shook his head. "Fine, then."he said, turning back to the club. "You girls are normally peaceful, but can have a powerful side. Same goes for plant life. That's why you have flowers as your symbols. But when they made us Heroes, they thought that we needed to have a symbol that was more often stronger than anything. Therefore, we got animals. You girls have the Spirits of the Garden, but us? We get the Spirits of the Jungle."he explained, before the Club nodded. "Fair enough. If the Taisha ordered you to help us, who are we to say no?"Fu said, extending a hand. "Welcome to the Hero Club!"she said, before Adam looked at the hand, and shook it. "Right, so my next question is..."Jamie said, looking round the room.

"What do we now?"


A/N: And I hope you enjoyed this chapter. This is more or less an experiment to see how the characters of Yuki Yuna and the two brothers of the Team ARKS universe meld together. I'll upload the next chapter when I finish it. See you all then. Madman out!
