Hey guys,

Welcome to my new BNHA and RWBY crossover fanfic, thanks for checking it out, even if only for a second. There's not really a grand reason that made me decide to write a crossover with these two series (ignoring the frighteningly small amount there are), an idea simply popped into my head and I thought it would be a shame not to act on it.

As you can see from the labels above, I'm aiming to make this into a story revolving around Adventure/Humor, but I won't shy away from some romance should it feel natural. It's just that I've never written anything romantic before, and because of that I am unsure how well I can execute it, hence my hesitation to add it as one of the major driving points of the story.

Now, I know I'm far from the best writer out there, so I'd appreciate it if I could get some feedback, be it good or bad.

I hope to be of some entertainment to you all.

What was it that made a hero?

It was a question he'd always asked himself, something that had bothered him as a child, and continued to do so even up until this day. Was it their armor or quirk, the trappings of what made up those who stood up against the darkness of the world?

If so, he should have been a remarkable one; armed with the newest and best possible gear, and a quirk that essentially made his arms act as nukes, capable of leveling smaller settlements in one shot.

He wasn't though... or even if some thought he was, he sure as hell didn't feel like it. Though, if he was to be honest with himself, he doubted anyone would be able to hold their head held up high in his posistion, crushed to the ground as it was by Tomura Shigaraki.

Yeah...

Bakugou Katsuki knew he'd made a mistake.

A big one.

He'd made several in the span of his twenty-six year old life, some more devastating than others, but all of which he'd come to regret in time. Turth be told, there were more actions he regretted than not; disregarding and hating Deku in his earlier school years, cutting ties with his family and friends, ignoring ever growing health problems, just to name a few.

Joining Tomura's so called "League of Villains", strangely wasn't one of them...

Getting caught scheeming behind their backs however, that, he regretted.

The league of villains ravaged the already fragile society into submission and fear, destroying whatever invisible force All Might had created to keep evildoers in line. Shigaraki and his heavy-hitting companions spearheading their assault, there was little in the way of resistance. The biologically engineered monstrosities called simply "Nomus" were never far behind, either.

The impact of their movements were clear for all to see, the social structure was in ruin, jobs were shut down, public transport became obsolete, and kids having the possibility to get educated became a minority, the streets were no longer a safe way to traverse - filled to the brimm with all kinds of scum laying in wait for whatever poor fool deemed it neccesary to step out of their house.

Heroes didn't take all this sitting down, naturally, but the league proved hard to follow, as whenever the heroes reached the point of interest, all they were met with was the remains of whatever ungodly act was done.

To counter this, he joined them, planning to leak out any and all information he could get a hold off.

And it worked wonders! He had been able to prevent a lot during his years among them, robberies, genocides, abductions.. It was only a question of time however, before they started becoming suspicious. And that they did. There were only so many times the league would show up at the location and all they were met with was the never-ending wave of heroes, always looking prepared, without any civilians in the surrounding five miles, and not think anything was wrong.

A random leak of information? Sure, it could be looked upon as such, the first few times. When things weren't changing however, it became obvious there was a traitor among them, a rat. Shigaraki was no dumbass, the man child gone and the evil mastermind present. Just as Deku had become a better hero, he had become a better villain. Shigaraki schemed and played with people as if they were his own toys, doing acts and manipulating in ways he was sure even the deceased all for one user would be proud of.

Bakugou was able to keep them off his back for a good amount of time, but they managed to figure him out in the end. Proven by the situation he was currently in. Maybe the refusal to participate in missions where the goal was pure manslaughter made him stand out? His hands were by no means clean, many innocent people having been sacrificed to his exploisons to keep his charade up, but he tried to avoid it whenever possible.

It was too bad then, that his quirk shined the most when mass destruction of life and property was the goal.

Did the ends justify the means? Could he face the fallen and say their sacrifice was for the greater good? Could he have saved more lives, and had a more positive effect fighting on the other side? Was he any different from the rest of the League?

He didn't know, and he feared for his sanity should he dive deep enough into that line of thinking.

All of the information he had been able to get a hold of - he had passed on to the only one who knew of his intentions when joining the league, the only one who managed to somewhat brigthen the days of the average Joe.. The mighty "Symbol of hope", his first and only remaining friend - Deku.

Fucking Deku.

He wanted to laugh, honest. And if it weren't for the fact that his lungs had been turned to literal dust a few seconds ago, he would've. If only for the absurdity of it all.

The muttering dumbass who's testicles only dropped down when someone else was in danger, the very same now led the worlds most powerful oppostion to the villains. "The hero brigade", it was called. Many of his frien - no, former friends filled its higher ranks, Todoroki Shoto standing far above anyone else as Deku's right hand man. The hesitant fire and ice boy he so clearly remembered fighting in the finale of their first year sports festival was no more, the boy now a man with a mind and body of steel. Whenever the league moved it wasn't Deku they feared meeting the most, as while he was overwhelmingly powerful, the man more often than not chose to have mercy on his enemies when possible. No, it was Todoroki they feared, as he held no such reservations. He was as close to a boogeyman for the villains one could get.

Slowly but surely, the brigade were wrestling the control of society more and more in their favour. Currently it looked like a stalemate, two sides controlling equal amounts of the world, both waiting for the other party to make a mistake, only to then seize the moment to fight for a devastating victory. And in doing so, cementing their motives and values as just, springing society into two possible futures, peace or chaos.

However, it would seem that was a fight he would not be able to take part in...

"Hey." a raspy voice sounded from above, hand tightening around his neck as it spoke, followed by the dematerialization of his left hand, creating a fountain of blood spewing out of the stub left behind.

Fucking Deku.

"It hurt, you know." He continued, having no care for the violent spasms Bakugou made trying to get away.

Fucking Deku.

"Being betrayed... You can understand the reason you're getting punished, right? Right?" His grip tightened, making Bakugou's face pale from the lack off proper blood flow.

Fucking Deku.

"It's your fault really, if you think about it. This isn't something I particularly enjoy, you know?" His red eyes said otherwise.

Fucking Deku.

"So much power wasted... Still, I think getting killed would be a proper punishment, what say you?"

Shigaraki leaned in closer, exposing the earlier shadowed grin plastered all over his face, red eyes gleaming maliciously.

"Hmm? No objections? Great!" His hand tightened once again, crumbling his one remaining hand in the span of a second, allthewhile grey almost moldy cracks started to appear all over his body, blood spewing out of every new gap his body got.

Come on you shitty green-haired fanboy!

"SMASH!"

It was all the warning Shigaraki would get, as not even a second later a huge green fist made it's devastating mark on the young adult's face, sending him off at speeds which could give racing sports a bad name. He went far and fast, rocketing through at least a dozen buildings before finally stopping.

Dust settling down, and forcing himself to look up even while experiencing mind-numbing pain, he was able to see a massive figure come into view, a familiar one, a green one. He stood tall and proud as he always had since graduating, his back slightly turned against him and a smile on his face, oozing protection and justice to all who would be in his presence.

"I am here," he said while turning around, facing Bakugou for the first time since arriving. "Let's go get him...?"

It was a small shift, a subtle thing, one he wouldn't have been able to pick up on had he not known the bastard for the majority of his life. He was still smiling, but the way his eyes widened in terror for a split second told of his feelings more than any words could.

"Come on, Kacchan. This is no time to be lying around, a love tap like that won't keep Shigaraki down. I need your help, the rest of the team is keeping Shigaraki's lackeys busy outside, it is up to us to finish this."

Bakugou fumbled his way to a standing position. It truly was a miserable sight to behold, his mind not having fully caught on to the implications of losing both arms yet, repeatedly trying to use them both for support on the way up. Yet, Deku did not give any support, choosing to stand a few feet away with a confident look in his eyes and a bright smile. Bakugou agreed with that decision, for had he given him an inkling of pity or help, he would be blown up, missing arms be damned.

Finally standing tall - although wobbling constantly with smaller breaks in between, he gave Deku a nod, signalling he was ready to move on.

"Awesome!" Deku shouted while flashing his ever famous thumbs up, it was a recurring movement whenever he was interviewed on TV, though this was the first time Bakugou had seen him do it in person.

Turning to familiar actions when panicked... God how obvious can you be? Pisses me off...

Bakugou tried shouting at him, wanting to tell him to get his act together. No coherent words came out however, only a stream of blood not unlike when All Might used to strain himself. Not expecting the liquid, Bakugou started coughing up a storm, starting what first seemed like an endless cycle with blood - coughing - blood and so on. He finally stopped however, after laying down on the floor in a fetal position. Twitching violently with a hazed expression on his face, the lack of oxygen finally showing its effect.

Deku's eyes widened again momentarily, tears threatening to fall, but he could not allow himself to let them go, for they would surely send Bakugou into a rage that would further destroy his body. Brushing away the potential tears from his eyes, and steeling himself for what he now was sure to come, Deku walked over to where Bakugou was lying.

"You stay here and wait for my signal okay? I'll restrain him, and when my cue comes, you come and blow him up okay? Just like the old days."

Just like the old days huh...?

That sounds...

Nice?

Yes.

Those were good times, easier times...

We were a good duo...

On the same side, fighting evil with both relentless fervor for winning and an unending want to protect...

Deku turned frantic now. "You hear me?! Rest here and when I give the signal, you quickly come over blast him, you got that?!"

Rest...?

Yes.

I think I'll go ahead and do that...

The world turned black a moment later, Bakugou closed his eyes, never to open again.

Or, so he thought.

"Congratulations Miss Goodwitch, you've birthed a healthy baby boy!"

Well, you made it through, thanks for reading.

It's not long, I am aware, as it is a prolouge and only meant to give a brief idea on what it's about, I intend to flesh out a lot more next chapter.

But I repeat: feedback is greatly appreciated.

Cya around!
