Hello everyone. This is the Gemmysaur with his very first story so if there's a few (a lot actually) of errors, be it grammar, spelling, character interactions, etc., please tell me. Constructive criticism are a yes please, flames are kinda ok if there's good reason for it.

There are plenty of stories I want to start off, but the problem is they're just that. Starts. So, hopefully this one will kick off well enough for me to be able to continue it.

A fair bit of warning though, since this is my first story, I would want to spend some time to do the next, or fix this one, so expect irregular update times if you actually liked it. Not that I'm holding on to the wish that you would. Yeah.

Lastly, I own neither franchise; Naruto and RWBY.

Chapter 0: Authority of the gods

I was wondering. What the hell am I doing again? Here I am, in my all black ninja clothing, topped with a black overcoat and a orange, one-eyed spiral mask, facing the only man in history to ever garner a flee-on-sight order. In front of me, wearing his standard-issue jonin uniform topped off with his signature white haori that signifies his rank was the dreaded Konoha's Yellow Flash. It seemed stupid at first, but I'm ready. I knows his moves. I have the trump card that can beat that man. I am Madara. I am unstoppable, and with the Kyuubi I had extracted from the man's wife, I will destroy Konoha. All of this is the start to realize my dream. Or rather, his dream.

So we moved. As always, my opponent is swift. He is too fast for me to defeat with simple taijutsu or ninjutsu, even when he doesn't use his favored jutsu. I had to use mine, so I did. The man sped towards me. I activated my trump card, the Mangekyou Sharingan's Kamui. With this power, I simply phased through the tri-pronged kunai that was supposed to cut my head off, continuing forward as the man went right through me as well. Solidifying, I yanked on the chains trailing behind me by my wrists, catching the fastest man alive with it. As I turned around to phase him to another dimension, the man has already disappeared. He had thrown his kunai at a nearby tree and flashed to it. Damn.

I trembled. I, Uchiha Madara, the current holder of the name anyway, am obviously hard-pressed in this very short fight. Namikaze Minato, the Fourth Hokage didn't get his moniker for nothing. The guy is extremely fast. Still, it mattered not. I will win, and I will enslave the world, and I would do so to make sure that that same world will never ever have wars and fights for power again.

I tried again. This time I will succeed. As we were about to clash, he threw his kunai. What's he thinking? A diversion? Does he intend to teleport behind me once that kunai lands? It obviously won't be hitting my forehead despite it being in the kunai's trajectory. No matter. That's his mistake. I will simply pull him in the moment we touch.

Not even half a second passed, and here we were. My hand was to reach out to him, to ensure he can't dodge my trump card. The kunai he threw, uselessly phasing through my head. He still hadn't made another move. Perhaps he realized as well that he already lost? My hand reached out as my instincts begged me to fall back. As my fingers closed in upon his vest, he finally made his move. A ball of pure chakra rotating at high speeds, a Rasengan on his right hand. I see. He wants to finish this in one move as well.

My real hand felt cold. My heart was racing. My thoughts are muddled, but I continued anyway. I will win. As my fingers finally touched the material of his vest, I closed my hand on it as I willed my Sharingan to suck him in once more. I missed. With a flash of yellow, he disappeared once again. Then I realized it. The kunai was no diversion. He was above me, teleporting to the kunai he threw at my head, Rasengan in hand.

With great force, I was slammed to the ground, destroying the area around us as well. My mind blanked in pain as he spoke of something. Something about a level 2. I lost. I had to leave. I felt his hand on my back, then felt my control over the Kyuubi fading. A seal, I see. That was what he was after. This man has utterly beaten me. It looks like I am not yet up to par with my title. With my thoughts racing, I willed myself away as I saw him do so as well.

I appeared in an abandoned living room. It was my home before, I think. What else did he do? My mind was clouded with pain. It hurts! It hurts! It hurts! It hurts! All through the pain, my mind cleared. Clearer than it had been for years even. The compulsion was gone. The damned compulsion that that damned being that saved me planted. That damned compulsion of taking up Madara's will and way to save the world. Now that I think about it, it was twisted. To trap the entire world in an illusion was just too twisted. I was about to check upon Zetsu who is keeping me alive, but the pain stopped me. The pain again! It hurts so bad.

I pushed through the pain and checked on Zetsu. The reality of the situation hit me. The seal planted on me was meant to keep me immobilized. Fortunately, or rather unfortunately, he touched the part of this body that was made up of Zetsu instead. The same Zetsu that was keeping me alive is now incapacitated and cannot support me. It was the reason for the pain, my body is slowly giving out due to the lack of support from my partner.

I deserved it maybe. I did try to destroy the place that I always said that I will one day lead. At the very least, I could make amends. I need to talk to them, to Kushina-san, to Minato-sensei. Maybe they'll believe me. Maybe they'll save me, let me help. I hope so. With great pain, I righted my self. The side of my body that Zetsu forms is just dead weight right now. I have only my own chakra to do this, I thought as I used my Sharingan's Kamui technique to find sensei.

I managed to find the Kyuubi easily enough, and subsequently, Minato-sensei who had apparently teleported away to get Jiraiya-sama's aid while I was wallowing in pain earlier, if what these shinobi I am hearing is correct. At that moment, I felt how very much doomed I was facing my sensei. He teleported an entire Bijuudama away from the mountain and towards a far-off location, and then proceeding to dump a giant sword-wielding frog over the Kyuubi. As expected of sensei, he's got this. My mood brightened a little when I thought about how Minato-sensei knew full well what to do in this situation. And with the help of Jiraiya-sama and Saindaime-sama, the beast's rampage was all but contained.

I focused chakra on my ears, listening in on what he is talking about with Kushina-san. I know him well enough to tell that sensei noticed me listening. He must've felt me limping closer by the trees some fifty or so meters ago. I saw Kushina-san. Her face was pale, her bright red hair lost its shine, her eyes spoke of pain not unlike mine, she's in a very bad condition, but it looked like she'd live. Seeing her like that, my heart felt like it was being wrenched from my chest. Although I was under influence, I still did something very bad to our resident team mom.

I strained my ears further while focusing my chakra. What I heard made me want to rip my heart out. Sensei planned on sacrificing his own life and his son's future to save the village. He had only called for Jiraiya-sama's help as well as that of Sandaime Hokage-sama to stall the monster while he prepared the seal. I watched with halted breath as Minato-sensei performed the hand seals for the secret jutsu that will end his life. I had to do something. I had to atleast save either his or his son's life if not both. So I did. I mustered my courage and used Kamui once again to get there fast enough. My eyesight slightly diminishing from the lack of Zetsu's empowerment.

He noticed, but he didn't look at me. He either thought I was no longer a factor to worry about, or he no longer had the capacity to do so. He was in pain. I looked at him and his son with my Sharingan and found out why. Massive amounts of chakra are being pulled into both of them. While watching, a tired Sandaime-sama approached me with great caution, staff drawn. He was still wearing ancient armor, probably from the Shodaime and Nidaime's time. It looked like a samurai's now that I think about it, though the massive staff that seemed too thick to wield ruined that look.

"So, you're the one responsible for this attack, Uchiha Madara."

Removing my mask, I answered back to the best of my capability, "Sandaime-sama, I am not Uchiha Madara. I'm Uchiha Obito, Minato-sensei's student. Please hear me out. I was under a compulsion, that sensei managed to remove."

His look of great distrust hurt more than that of my failing body. "Explain."

It was a sigh of relief that he didn't outright killed me. "After the mission where I was crushed by rocks, I was saved by a being who calls himself Zetsu under the orders of Madara. He became what is now half my body and is what allowed me to live for as long as I did. He is also the one who placed the compulsion on me to follow Madara's will, along with giving me the power to do what I did today. Please forgive me Sandaime-sama! Though I didn't intend to do what had transpired, I'll take full responsibility for it. Please let me help. I wish to make sure that atleast Minato-sensei and his son gets through this alive."

He looked to be in deep thought for a moment, though he didn't drop his guard at all, still holding onto his Adamantine staff. He then turned to me and asked, "I still can't say I trust you as anyone could've come up with that ridiculous tale. But, if I gave you the benefit of the doubt, what do you intend to do? How can you help? The Shiki Fujin is a summoning jutsu that will seal the Kyuubi and Minato with it in its stomach."

Unfortunately, I never got to answer it. I teleported towards my sensei. To Minato-sensei. The mass of chakra that my sole eye sees above him looks to have finally made its move. With great concentration, I sucked Minato-sensei away from the reaper's hands, or atleast, what I assume to be hands as all I see is an extremely faint moving blob of chakra.

Sensei turned from resigned to shocked. He probably didn't expect that Sandaime-sama let me through so easily. Then again Sandaime-sama didn't expect me to be capable of moving around like I did. Sensei looked at me before he was completely absorbed by my eye. He seemed to have many conflicting emotions. He seemed to have recognized me as both Obito and Madara. What a shameful student I became.

I screwed up was my thought as I was sending Minato-sensei away. The reaper's seal interacted with my Kamui, I think. It felt like it synchronized or something of the sort, and it's sucking out my chakra through the Sharingan. Bottomline of it is that I didn't send Minato-sensei to the Kamui dimension. I don't know where the hell I sent him. I screwed up bad. But at the very least, he's still probably alive, though it looked like I'm gonna die.

It entered my vision. While cutting off the chakra drain, or rather, I think it did, the reaper showed itself to me. It was a massive humanoid samurai-esque being wielding something that looks like a katana? A tanto perhaps? Had I been the same as I was prior to getting crushed by rocks, I'd have pissed my pants. For now, I settled with sweating profusely and whimpering in fear, pain of using up a massive amount of chakra and deteriorating body forgotten. It spoke.

"Child, you have disrupted my ceremony. You have taken away the soul to be the payment for my service, and you had the nerve to interact with my dimension. I will take a life in replacement for my payment, and another for your disrespect." It's voice held great power. It felt like his mere gaze would pull me inside out. This was what Minato-sensei was summoning!? He'd have to be a special kind of crazy to do so. But then again, it's my fault to begin with. Sorry sensei.

My mind raced as I saw its hands moving towards me. It's eyes hollow, it's aura cold. While I held back my tears of fear, I spoke. "Will you not harm this child and his mother? Will you take this dying me and this abomination for a body part in place of another human?" I pointed towards the Zetsu that was supposed to keep me alive.

The reaper spoke, "I care not for what life I take, so long as the price is paid."

With a resigned sigh. I raised my own arm as to accept it. I really screwed up didn't I? Maybe I could've dragged Kakashi away that fateful day instead of throwing him out of range of the collapsing parts of the cave. Maybe I could've gotten Kakashi to flare his chakra at sensei's kunai. Maybe I could've done that myself instead of trying to be a hero and save Rin.

Rin. I wish I could've been a cooler person. Not as cool as Kakashi though as that was just cold. I wish I could've saved her that time it was revealed that she was a jinchuuriki as well. I wish I could've pushed her out of the way of Kakashi's Chidori. I wish I could've spent more time with her. That smile was what kept me going, along with my dream of being a Hokage.

Kakashi. That forever-masked, white-haired bastard. I wish I could quarrel with him once again. He was there somewhere, trying to help stall the bijuu I set on them. I wish I could've been there to help him, but then again, it's better that I'd wish for not being found by Zetsu in the first place. Atleast then, he'd be safe and not in this situation right now where he may very well be a cold body.

I look towards the silent, teary-eyed Kushina-san who seemed to have recognized me. She who had no idea that I was the one that attacked Konoha. She who had no idea I had been the one to rip the Kyuubi out of her belly. She had no idea I just had a deathmatch with her husband. She who had treated Team Minato as her own children while her husband, our father figure. She who looks at me with sadness and fear of losing a child who had just returned.

I wanted to make it up to her but don't know how, so the stupid me said the most memorable thing I have done before.

"Kushina-san. I'm sorry. Please, make use of my remaining eye. Please keep it for your son to make use of. This is the only thing left I have that I can give to you as my payment for what I have done." I tried to hold back my tears, but I can't. A little bit of water came through the dam that is my eyes, or rather eye as the other is not really mine. I don't have use for it anymore anyways. My chakra is nigh-depleted and I am about to be swallowed by a giant ghost samurai thing so it is best that I gave it away. I spoke again.

"Please, forgive me Kushina-san." The dam broke.

Then I look towards her son. I never caught his name. I see in him his father, a man I respected. I see in him my atonement. I see in him the hope of the future. And I am happy to say that it is this child that is the last thing I will be seeing.

"Goodbye and I am sorry, kid."

Legendary

My mind can't wrap itself around what was happening. It was supposed to be the happiest day of our lives, my husband and I. It was the day I gave birth to our little Naruto. I was scared and ecstatic at the same time. Scared that the Kyuubi might find a way to come out, but my husband is there to make sure it won't happen. Ecstatic that I will finally be able to hold my child. I was concentrating solely on that latter thought. It was what kept me going at the time. Then the everything went upside-down. A masked man came, took me away from my husband as he threatened my baby.. It was a good thing my husband is the fastest man alive. He was able to bring little Naruto to safety, then came back to save me as well, but even he wasn't fast enough. The Kyuubi was extracted, and I was left for dead.

I woke up a while later with our baby beside me, Minato missing, presumably fighting against the masked man. I was scared. Will our little family be broken just as quickly as it was finally formed? I held on to the hope that he will return alive and well, with the Kyuubi locked away and Konoha safe. I was still weak. I wished that I could join my husband in battle but alas, giving birth and being ripped of your tenant really takes alot out of you. I suppose I should be happy that I am blessed with the Uzumaki lineage's ridiculously strong life force, else, I would've died on the spot.

I drifted in and out of consciousness. What was I thinking about earlier? I looked around a bit, and saw that my husband had returned. His face still bright blonde and spikey. His clothes have not so much as a tiny cut that I can see. I sighed with relief but my breath stopped immediately. Minato's face was of great worry and fear.

He must've thought up a plan to subdue the monster, but it looks to be something that will cost us dearly. I prayed not. I prayed that his expression was only because he was facing a monster. He was a beansprout like that. I prayed that he will return safely after saving everyone. He always does. All of those thoughts came crashing down when I saw him pick the baby up and whispered to me that there is no other choice he can think of at the moment.

He told me he got Jiraiya-sensei back in Konoha to keep the beast busy while he prepares the seal and the storage. My heart ran cold when he looked at Naruto. I cried. I told him to take me with him. I told him to seal it back with me, but he didn't want to take any chances. He had no choice. He didn't want to intrude upon any other family that has already lost so much in the Kyuubi's attack. So I told him to bring me with him, to hold my child for as long as possible. He complied.

"Minato, is there no other way?! Can't you just send it somewhere else?" I cried in desperation as Minato prepares for the sealing.

"I'm sorry Kushina but you know as well as I do that I can't just do that and hope for the best." Minato, with a scared look on his face and great determination in his eyes, said.

Shiki Fujin. The strongest sealing jutsu created by my clan. I always wished that I will never see the day that it will be used. To think that it will be used on the day of my giving birth, by my own husband, and on our own child no less. It was the worst possible thing that ever happened, far more than anything I had ever thought off.

I see Minato looking to be almost finished with the jutsu. No doubt, from how he looks, that the reaper is already doing its thing. I did my best to calm my little Naruto down while I helplessly watched on as my husband was about to be taken by the sealing jutsu, while the Sandaime Hokage I think was talking to the masked man, this time only limping as it seemed my Minato did a number on him, and Jiraiya-sensei was keeping the rapidly weakening Kyuubi at bay. It looked to be in its final stages as the beast is no longer in sight, which is when Minato's soul is to be taken away, when someone suddenly appeared in a spiralling fashion and looked to have teleported my husband away. The masked man, unmasked.

Looking on, there was only one thing in my mind. "Obito-kun." He was pretty badly beat. His entire left side looked to have been entirely limp, his clothes ripped and his chakra rapidly draining.

As I was losing consciousness, I caught a few words Obito-kun was telling the reaper. As I was drifting in and out of consciousness, I pieced together what my husband's supposedly dead student was saying, and was confirmed when he fell down like a puppet with its strings cut. Obito-kun replaced Minato as the reaper's prisoner.

Though that left one last thought in my mind before I passed out. Where the hell did my husband go?

AN:

Hello again everyone. Thank you for managing to reach the end of the prologue of this story. Yes, it's pretty much the telling of Attack on Konoha, though with big a big twist. I noticed Minato is extremely underutilized in the manga, though that is because he's way too good if he's done properly.

I mean the guy is a sealmaster, learning from the best Fuinjutsu-masters in the world, the Uzumaki. He has massive chakra and super-fast fighting style, but lacks any jutsu of note that can do damage. By the end of the manga, the only attacks he had were Rasengan, which is unfinished but is strong enough to likely destroy a city-block by itself. Gamabunta-drop which, by the bosstoad's mass alone, would wreck multiple city-blocks, but requires being dropped from a high place, and needs to have a summon ready. Lastly, is the one with the ridiculously long name that Minato never even got to use. He only mentioned it in the fight against Juubito, tried to do it two or three times before leaving it aside.

Here, I gave him a fuinjutsu based on Naruto's magnet-release Rasengan. One that pretty much disables an opponent on hit. The difference is that this one doesn't do damage and that the opponent won't struggle when it's being applied. It's not going to be overpowered as my headcanon says it can be broken by flaring enough chakra, but Zetsu isn't the best when it comes to that so there's that.

Also, if you may have missed it at the top, this is a crossover with RWBY, which I think is a good place to send him at.

People of similar speed? Yes. Minato was calced around Mach 100-200 for running across the countries, ran to the middle of the ocean, leave a kunai, run to the Shinobi alliance, just in time to catch a Bijuudama midflight, redirecting it to the ocean. The people of RWBY scales roughly the same because of Emerald and the gunboots guy who dodged cloud-based lightning relatively easily. This is ignoring Minato's telespam combat though.

People of similar power-level. Yes. Minato's strongest attack at the moment is Rasengan since he didn't get to bring Gamabunta along with him to another world. RWBY has similar feats of power by virtue of Ruby Rose physically dragging a Nevermore up a cliff with Weiss providing foothold to do so. You can find calculations for those online.

Lastly, his powers can be explained as: Rasengan being an aura-based attack, Hiraishin being his semblance, and Fuinjutsu being an abstract application of high aura control.

Yeah. That is all. Thanks again readers, if there are any. Comments? Suggestions? Follows and Favorites? Yes please.
