Azur Heroes

Chapter 1

Well a few people liked this in my Multiverse story, so I decided to make it an actual fanfic. Most of this first chapter will be copied from that chapter, but I will also be adding in more details. So on with the show.

(Izuku POV)

'Not all men are created equal. I learned that the hard way when I was just a child.' Izuku think to himself while a five year him is standing in front of a boy who was trembling. Opposite of him was Katsuki Bakugo and a few others. "I won't let you hurt him Kaachan!"

"What do you think you can do? You're just a worthless quirkless weakling!" Bakugo says while sparking up a few explosions from his hands. He and the others then start attacking me and mocking me all the while. Once they were done, I was laying on his back with bruises and burns on my body.

'I still want to be a hero despite what everyone else said. But I often wondered what that could mean.' Izuku thinks, now looking about nine or ten years old. I was walking back home sadly after another round of bullying from Kaachan and the others in our class. Though sometimes I question what it means to be a hero. For most it is all about the use of their quirk and saving lives through using that. For others its about fighting villains with their quirk again.

But don't some heroes don't fight on a frontline. There are plenty who fight by making strategies to defeat villains. Maybe I could be a hero like that. I've been analyzing heroes since I was little. Maybe I can turn what I've learned into being a strategy hero. I just know I have to prove what I can do in some way.

(No POV)

In a different part of Japan, a short bald doctor was analyzing a strange glowing cube. "Sir, the master is still barely responsive. I doubt he'll ever be able to be his best again," the black misty villain Kurogiri said with Tomura standing behind him. The doctor nods before saying, "a quirk may not….. but if what I suspect this cube is capable of, we might be able to." The doctor demonstrated by using the energy of the cube to restore a broken machine. As well as restoring a damaged plant. "Well what are you waiting for?! Please! Heal sensei!" Tomura says desperately. The doctor looks to the boy, then the cube again. He sighs before agreeing.

The doctor, Kurogiri, and Tomura went to a different room to meet the injured man inside. The top of the man's head was destroyed and was hooked up to multiple machines to help him breathe. This was All For One. "Master. Your injuries following your last fight with All Might are too great to heal with the science and quirks we have access to. But with this might be able to heal you," the doctor says to the slightly responsive man. AFO turned to the doctor and with a raspy breath says, "do it….."

With a nod, the doctor set the cube on his master's chest. When it didn't activate right away, the mad scientist attached a few cords to it and ran some power through it. The cube then started to light up more and more. With the three observing, their eyes widened and were hoping the master would be revived. Suddenly the cube starts to float and glows brighter and brighter. Suddenly a bright flash covers the area blinding all who could see.

When the light fades, the cube is gone. But AFO was not restored. Instead floating above the group was a woman with ghostly pale skin and hair. She had a strange bow and fox eared combo above her hair and was wearing barely anything over her chest and lower body. She had a teasing smirk on her face. But what was eye catching, was the mass of tentacles and futuristic cannons around her. "So…. Were you the ones who brought me here?" the woman said with an unsettling distortion to her voice.

Most of them are unsettled by this strange entity, but Tomura stepped up first to say something. "Who are you? And can you help heal my master?" The strange woman looks to her side and sees AFO laying on the bed with machines attached. She hums before saying, "you may call me, Observer. Not that it will matter much longer. It is time for we Sirens to see what this world has to offer." She then points her cannons all around and unleashes beams all around her. Vaporizing all the humans in the room.

With that done, she looked around before her smile grew. "Now then, let us begin." With a snap of her finger's portals opened around her summoning her fellow high ranked Sirens. The six then combine their energy and unleash a blast that destroys not just the hidden building but parts of the mountain all around them.

Suddenly around the world, more portals open and various Siren ships appear out of them. Some of the ships start flying around and blasting the cities near the ocean. While some high ranked Sirens suddenly appeared above the cities and start attacking the people.

In Mustafa, a few Sirens (Testers and Purifiers) start shooting all around. Izuku happened to be walking through the city and saw the Sirens arrive. After a few shots he saw that a few people are trapped. He hyper ventilates a bit before running to those who are trapped. Lifting up parts of the rubble to help them.

With the Sirens, Endeavor, Ryukyu, and over a dozen other heroes are engaging the invading aliens. But they are having no luck getting through the enemies shields and kept getting blasted back. "Who the hell are you?!" Endeavor shouts with a beam hole through his stomach. Purifier floats up with her hammerhead shark rig behind her. She starts laughing at all of them before saying, "name's Purifier! And I'm going to have fun ripping all of you apart!" She turns her cannons and drones to the heroes and starts firing at them.

Suddenly, All Might appears and punches the side of the woman to send her back. He is breathing heavily, but he still has enough energy to say, "There is no need to fear. Why? Because I AM HERE!" He then leaps up and attacks the Sirens a few times. With some shards and cubes falling when he breaks some gear.

But even he can't defeat all of the sirens gathered. He gets blasted back from a few Tester clones who start to mock him as well. "You are here? What good does that do when you can't even compare?"

Izuku was running down an alley way when he found a cube on the ground. He reached out and picked it up. It didn't do anything, but he was still curious. Suddenly he saw All Might get blasted back and hears the Sirens mocking his hero. Izuku then shakes out of his fear and runs to the number one. He then gets under All Might's arm and tries to help him up. "Oh, a courageous young one huh? Well, it won't matter soon," Tester says while pointing her guns at the two. She charges up and fires at the hero and boy. Izuku then turns and closes his eyes, sure that this would be the end. But the only thought going through his mind was, 'I wish I could have saved more people.'

Suddenly the cube he grabbed lit up and with a flash the beams were stopped. From the smoke, a few shots were heard ringing out. The shots couldn't be seen, but all of the sudden six Tester clones were destroyed. "What!?" Purifier says before getting struck by a round fired at her.

From the smoke in front of All Might and Izuku, was a very tall woman with fox ears and five black fox tails behind her. Her eyes are a piercing sapphire color, and her black hair is in a long ponytail. For clothing, she is wearing a kimono like garb with samurai armor on parts of it. Which is off on left arm and showing off her impressive bust with a sarashi tied around it and the waist is also exposed with just the large bow in front covering her private areas. As well as having black stockings that cover her legs, with tall geta sandals on her feet. In her left hand is a massive sword. She has a smile that just radiates confidence in herself.

Behind her body, is a set up with ten large gun barrels set in pairs around her. As well as a variety of other guns scattered across the mechanical set up. That is when she speaks with a confident tone, "well now, it seems we have some targets to face off with. Battleship Kii reporting commander!" With that said she leaps up and engages the Sirens with both sword and gun.

It takes about 15 minutes, but Kii manages to run off the high rank Siren and defeat all of the clones. But shots are still being fired from the ocean and the coast guard and JSDFM is having little luck against the enemy. Even the heroes like Selkie and Gang Orca are useless as even when they get on the ships, there is no one to stop and they can barely make a dent in the metal of the ships.

While Kii was fighting, Izuku stayed and helped a few of the heroes and others before falling back a ways. "What you did was reckless young man. But it was still impressive. You have the heart of a hero." All Might said to Izuku when they all had a moment to catch their breath. Endeavor begrudgingly acknowledged Izuku's efforts as well, as did a few of the other heroes in the area.

Ryukyu was about to ask why he didn't use his quirk, when Kii arrived and walked up to Izuku. She then saluted before saying, "the main force of the Sirens is still out there sir. We need to take the fight to them." Izuku looks around before asking if she was talking to him. With a smile, Kii nods before saying, "you were able to call to me and summon me to this world. Even though I had never been built by this nation long ago." This shocks everyone wondering what the woman could be talking about. Izuku tries to process this, but he can't.

Kii hums a bit before saying, "maybe this could help you summon more." She reaches into her sleeve and pulls out a handful of cubes to show the group. She then tells him to remember what he thought of when he summoned her. Izuku looks at the battleship woman like she is crazy, but he grabs two of them and thinks back again.

Nothing happens for a bit and Izuku gets discouraged. Kii then pulls the boy into a hug before saying, "don't overthink it commander. Just feel it." Izuku is shocked by the close proximity, but the woman's voice helps to calm his heart and he can remember the emotions that he felt when he summoned Kii. The cubes light up and before long, two more women appear before the group. While the heroes are shocked at what is happening (and Izuku is fumbling with his words and thoughts), the two new arrivals speak up.

The youngest looking of the two was a girl with white hair and bright red eyes and wearing an unusual sailor outfit. On top of her head are mechanical pieces that look like horns, and at her side are a set of cannons and two triple torpedo launchers. In her right hand though is a large sword. "Improved Fubuki class destroyer, Ayanami. I'm also known as the demon."

The older of the two new summons has a crisp white uniform on, with dog like ears on top of her head. The uniform while not showing skin, seems to accentuate the woman's impressive bust. On her legs are black garter belt stockings with white heels on her feet. At her sides are what appear to be ship sections with six double barreled cannons on them. Behind her back is a katana. The woman then speaks up saying, "Ara! What a cute commander. Please allow your big sister Atago to take good care of you from now on!" She then walks up and gives Izuku a hug.

Izuku is still not sure how to process all of this, but Kii helps him. With a smack of her sword to the top of Atago's head, she then says, "we have more pressing matters to deal with. Two cubes left commander, make them count." Izuku shakes out of the pleasant scent and comfort of Atago.

"Right….. Hang on." Izuku says, he grabs the two cubes and reaches out again. This time only one ship appears. It is another fox woman. But instead of black hair, she has silver hair and is wearing a blue kimono. Said kimono is draped below her shoulders, with her cleavage on clear display. On her legs she is wearing white stockings with her geta. Floating at her right side are trio of katanas, and on her left appears to be a runway of sort "I am called Shinano, an aircraft carrier of the Sakura Empire. Please allow the third ship of the Yamato-class, to guide you forward upon the right path."

Izuku is just stunned by what is in front of him and can't build a sentence. Kii notices this and puts a hand on his shoulder. "Commander. There are enemies out on the waters. What would you have us do? Fight to defeat the enemy? Destroy all in our path?" Izuku finally snaps out of it and thinks on what she said. Before saying, "no. You are going to fight to save everyone from these strange invaders. The heroes can handle evac on land. We need to fight back against the threat at sea… I think…." Kii nods before agreeing with the boy who summoned her.

She gives the orders to the three gathered before they head out for the water. While shocking at first, the heroes went along with Izuku's plan and orders. "You did well young man. We'll handle things here. Get yourself to a shelter." Endeavor complements then orders the young man. Izuku though shakes his head before saying, "no. I have to see them through. I don't know why…. But I feel I have to." With that he runs off toward the water to see what will happen.

Out at sea, Selkie and a few other maritime heroes have been badly injured or killed. Selkie is missing an arm, and Gang Orca has a hole in his stomach. Right as a few of the high rank clones are about to finish them off, Atago and Ayanami come out blasting and slicing through the enemy. They then land on the water, and skate around firing blast after blast at the Siren ships in port. Kii and Shinano are a bit behind them, but they also contribute to the battle and cut down their own number of Siren clones and ships.

Around the world a few others awaken ships from the past. Like a pair of men at Pearl Harbor. Both had family who had been stationed there long ago, and both had managed to awaken American ships. Marcus Miller an African American soldier at the harbor awakened Arizona and the destroyer siblings of Downes and Cassin. While a national parks worker David Rasmussen, helped Miller to evacuate others. He awakened the spirit of Enterprise herself alongside North Carolina and Minneapolis.

A young girl in Keil called out and Bismarck answered and helped to bring forth Prinz Eugen and Z23. In York and London, two people called out and summoned Hood with Javelin and Ark Royal supported by Fortune. At Norfolk, a young captain of a cruiser called out while trying to direct her crew and she summoned Long Island, Colorado, and Thatcher. Even some from Italy, Russia, France, and China were summoned.

Near Kure a young woman managed to reach the spirit of Taihou and with the phoenix carrier's help, she summoned Ise and Hyuga. And after a stellar and brutal battle, they were able to summon Yukikaze and Mogami to give them some smaller ship firepower.

With the first battle of this new war winding down, and Izuku standing at the ocean as the girls he asked to protect everyone fought on, he couldn't believe what had all happened. With Kii and Shinano using their strength and rigs to help lift up a few of the injured heroes, Ayanami could start collecting the cubes that had fallen all around the sea from the battle. Atago though went back to Izuku for two reasons.

"Aren't you going to help them?" Izuku asked when Atago returned to his side. She gave a gentle smile before saying, "I think it would be best to have at least some protection for our young commander. And I'm quite capable of that myself. But also, I think we could use a few more to aid us." At saying that she pulled out two more cubes and offered them to Izuku.

He was a bit surprised, but he did see her point. Izuku took the cubes in hand and tried to call out to whatever ship may be on the other side. It took a few minutes but he eventually called two more ships into their world. The first was a mint green haired cat girl with a blunt sword that seemed to have a variety of tools attached. And with a meow she introduced herself. "Nya commander! Its good to see you! Repair ship Akashi reporting for duty!" Izuku was surprised, especially with how short the girl was.

The second was a woman who could rival Atago with the warm demeanor and friendly appeal. She was slightly shorter than Atago, with horns on the top of her head and her black hair in pigtails. Her clothing appeared to be similar to a schoolgirl uniform, with her breasts being accentuated by the sweater she was wearing. Around her body was a rig similar to Atago's but much smaller. And with a playful voice she said to Izuku, "Eheh, I'm Nagara. Commader, have you been anticipating my arrival?" While looking at him like he was a cute little brother.

Izuku blushed again, but he coughed before regaining a bit of his composure. "Can you two go out and help the others with recovering people out there?" The two looked out and saluted before heading out. Akashi would go to the various ships, including the Okie Mariner, and repair the damage that the Sirens had caused. While Nagara helped to recover those who were injured or dead. She could not carry as much compared to Kii and Shinano, but she was faster and made good time on her trips.

With the first battles ended and the clean up and recovery being finished, the world could begin to look around and take stock of what had happened. While most were shocked at heroes like All Might and Stars and Stripes getting knocked around by the invaders, more were looking toward the strange entities that had been summoned and managed to actually defeat the Sirens. When it was discovered who had summoned the heroic ships, the militaries around the world began to try and recruit these warriors and the ones that commanded them.

And while Izuku was still quite young, the defense of him by both his ships, and from the heroes he had helped, kept the JSDF leaders from pushing him around. "If these monsters are going to keep coming, then I'm going to help fight. Even if it is from the rear guard and trying to make a strategy. I'll help them protect everyone." Izuku said with a shaky but determined look in his eyes. With that, each of the summoners were given bases to command and some actual influence to help fight against the newest threat. And thus the Siren War subverted the age of heroes in the world.

I'll get into some other details later with what has changed as well as introducing the other commanders. But for now the focus is on Izuku and what his role in the war will be. And how he'll be a different kind of hero from what he is in the manga. Also, I do have a reason for choosing the ships I did. For one, a few of the ones I had Izuku start with don't get a lot of love on the fanfic side. Heck Shinano and Kii aren't even on the lists of searchable characters. Plus this is fanfiction, so I'm allowed a bit of liberties based on the little we have of some of the personalities. Please review.
