The new generation of Super Sentai is born, and with Marvelous gaining his crew, the Earth now has a chance to fight back against the Neo Zangyack. With the flag of the Gokaigers being waved, the invasion of Earth won't be easy.

U.A Academy

Over in U.A Academy, Benjiro, Izuku, Toga, and Mei were now on the Gokai Galleon, ready to set off. Still, as they got ready, the school's teachers finally took notice of the Marvelous ship. From the principal's office, a small white chimera creature was sitting on a desk watching the monitor.

This chimera creature was Principle Nezu of U.A Academy, and right now, he was looking at the pirate ship with curiosity.

Nezu: A pirate ship that can fly and is most delightful. So far, they haven't done anything besides being near our airspace and haven't attacked anyone. The question is, why appear at my school?

As Nezu kept looking at the screen the door to his office opened and an older man with baggy eyes and tired eyes was seen coming into the room looking concerned.

This man was Shota Aizawa, the underground hero Eraser Head and teacher of Class 1-A. Eraser Head was looking at Nezu, wanting to know what they should do with the flying pirate ship in their academy.

Eraser Head: Nezu, I don't usually question your methods of running this school, but why did you invite a flying pirate ship here? Better question, who do you know that owns a flying pirate ship?

Nezu: Nobody, Aizawa that ship just came to our academy for some reason.

Eraser Head becomes dumbfounded momentarily and just looks at Nezu, wondering why he hasn't sounded the alarms.

Nezu: If you are wondering why I haven't done anything so far the ships seems to be docked and I checked all areas of U.A and nothing has happened. No breaches, no information being hacked in, and most of all it did not attack. Whoever this individual is either just doing a publicity stunt or which may be concretely trying to recruit people.

Nezu then stops speaking and grabs some cheese from his drawer, and eats it.

Eraser Head: And you are completely fine with our students potentially being recruited by some unknown Pirate Captain?

Nezu: Oh heavens no. I am just keeping an eye out to see what this Pirate is going to do with my students. If what I find is true that he wants our students to be Pirates of a bygone era then we spring into action but for now, let him think he is getting his way.

Eraser Head pinched the bridge of his nose in frustration at the principal's words.

Eraser Head: Should we at least send a teacher to the roof? Some of the students go up there for lunch. For all we know they could be talking to them right now.

Nezu agreed as that would be the best course of action.

Nezu: Thank you, Aizawa for volunteering. Please, get as many important details as you can.

Aizawa looks at Nezu not amused but in fairness, he still holds him accountable for expelling his whole class for not having the drive to be a hero, so it was to be expected.

Eraser Head: Fine, for everyone's sake I hope this is just some kind of publicity stunt. I mean a flying Pirate Ship? What next, aliens?

Aizawa sighs and heads to the rooftops and as he leaves the room Nezu's computer starts to show something coming down to the planet's surface.

Nezu: It seems that strange Space Debris is heading to Musutafu.

Nezu looked at the monitor curious but also concerned about what was heading towards the city.

Ten Minutes later

After Ten Minutes, Aizawa was seen heading towards the roof but as he got there he saw Marvelous ready to leave.

Aizawa: And who exactly are you supposed to be?

Marvelous: Captain Marvelous the Third, Captain of the Gokai Galleon and leader of Kaizoku Sentai Gokaiger at your service.

Aizawa looks at Marvelous hearing that name as he had never heard of these Gokaigers.

Aizawa: Gokaigers? Is that some kind of criminal group?

Marvelous: Criminals? We are Pirates yes, but think of us as dashing rogues who fight against evil, we just don't play by the rules is all.

Aizawa then frowns as he knows they aren't villains but vigilantes heroes who follow their own rules.

Aizawa: So vigilantes? You know you need a hero license to do that stuff right kid?

Marvelous remained silent for a moment before locking eyes with the pro hero.

Marvelous: Tell me Mr. Pro Hero, does the term Super Sentai mean anything to you?

Aizawa became silent as he didn't know that name but for some reason, it felt it held some sort of significance.

Aizawa: I'm afraid not, is it something important?

Marvelous: In an age of heroes, earth's first heroes have been forgotten, reduced to mere myth. A shame, however I ask you don't judge my crew and I so hastily. Those forgotten heroes, who defended this planet long before the development of Quirks, we carry their legacy. That is this planet's greatest treasure, in other words, the legacy of the Super Sentai.

Aizawa was shocked but also confused as the idea that heroes existed in the era before quirks was hard to believe. Aizawa was about to say something until his phone as well as everyone on campus started to go off.

Aizawa: What now?

Aizawa then takes his phone out and as he does his eyes widen seeing spacecraft of sorts flying above the city.

Aizawa: What in the world?

Marvelous: Neo Zangyack, looks like they are sending their first monster to invade. I must set sail Mr. Pro Hero, my crew and I have work to do.

Marvelous then goes to wheel and then sails the Gokai Galleon away from the academy which Aizawa tries to stop him by using his capture cloth to grab the railing which sadly did not make it due to being too far away.

Aizawa: Dammit, what was that kid on about? Super Sentai? Are there any records of such a thing? Questions for later, I need to inform Nezu of this.

Aizawa quickly headed back to Nezu but as he did the Gokai Galleon was heading toward the city.

Musutafu

In the city of Musutafu, the people were looking at the Spaceship scared as to what it was hovering over the city. Nobody moved until a holographic projection appeared showing an alien creature of sorts.

This alien was Gyakusatsu Gill, the Emperor of the Neo Zangyack.

Gyakusatsu: Greetings humans, my name is Gyakusatsu Gill the Emperor of the Neo Zangyack. You maybe wondering why I am on your mud ball of a planet. Simple really to take revenge for the humiliation my family suffered from your heroes! For a Century your heroes the Super Sentai have stopped all evil ranging from here and the rest of the universe however it seems your heroes are no more and now I will restart the conquest that my grandfather started! Prepare to be conquered and those who decide to get in the way well you will be slaughtered.

The transmission then ends and a green light appears on the street and strange soldiers appear as well as a shark-like creature leading them. 

The shark-like monster and soldiers were Sword Shark Mask and Gormin Sailors.

Sword Shark Mask: It has been over a hundred years since my humiliation, I have waited in the depths of hell since 1975 for an opportunity like this! Gormins, destroy all whole stand in Neo Zangyack's way!

Sword Shark Mask pointed his naginata forward as the Gormins raised their weapons before marching forward. The Gormin Sailors aimed their rifles and then fired upon the civilians causing buildings and vehicles to explode. Chaos then erupted and people started to run for their lives, but as they did, three Pro Heroes appeared on the scene.

These Pro Heroes were Kamui Woods, Mountain Lady, and Death Arms.

Kamui Woods: Stand down alien invaders!

Mountain Lady: I hope you aliens are ready to fight a Mountain Lady!

Death Arms: You aren't going to get away with attacking the civilian's evil aliens!

The three heroes then charged and Kamui Woods used his quirk to send wooden spears while Mountain Lady grows into a giant woman while Death Arms reels his fist back ready to slam Sword Shark Mask. However as Kamui Woods and Mountain Lady attacks got closer the Gormin Sailors fired upon them. Kamui Woods wood was destroyed and the hero then gets blasted getting sent into a window while Mountain Lady was hit with a barrage of lasers and she falls down on the ground in pain and then shrinks back to her normal size. As for Death Arms he didn't make it far as Sword Shark Mask blocked his attack with his sword.

Death Arms: How is this possible my quirk should have destroyed your sword!

Sword Shark Mask: Is this really earth's finest? Over a hundred years have passed since my defeat at the hands of the Gorengers and this is the resistance I face on my return? Pathetic....

Sword Shark Mask swings his naginata upwards, slashing Death Arms across the chest, sending him flying backwards through the air before crashing in front of Kamui Woods and Mountain Lady. The civilians looked in horror and shock as the heroes were defeated by the alien invaders. All hope seems lost until a barrage of cannon fire impacts the ground around Sword Shark Mask and the Gormins, knocking them off their feet. Everyone looks to the sky to see the Gokai Galleon flying high in the sky.

Sword Shark Mask: Who dares to stand against me?!

Marvelous: That would be us!

Suddenly ropes lowered from the Galleon as Marvelous repelled down to the ground. He was followed by Benjiro in a blue leather jacket, Izuku in a green hooded jacket, Mei in a yellow bomber jacket, and Toga in a pink coat. The Civilians, Pro Heroes, and Neo Zangyack look at them.

Death Arms: Those kids are going to get killed. Dammit, why can't I get up?

The Pro Heroe was still in pain from Sword Shark Mask's attack.

Marvelous: You three rest, let us Pirates take it from here.

Sword Shark Mask: Is this what you resort to? Children? How sad, although I am rather bored. Don't die on me to quickly!

Marvelous smirked before he and his crew lined up facing the army.

Marvelous: Neo Zangyack, you will regret ever returning. You who think they are entitled to the universe. As a pirate I can't help but wanna beat the crap outta you!

Benjiro: Double for me!

Izuku: Triple, you will not harm our planet!

Mei: I hope you are ready because I am ready to test these babies out!

Toga: Captain, shall we get started?

All five flipped open their Mobilates before holding up their Ranger Keys before they folded in half, revealing the key.

All Five: Gokai Change!

The five inserted the keys into the Mobilates before turning them, causing the top half to unfold into crossed swords.

Mobilates: Gokaiger!

A red X passed over Marvelous forming a black bodysuit, a second formed a red coat with a popped collar, finally a red V passed over his head forming a helmet themed after a pirate hat.

An X passed over the other four in their respective colors, forming a black bodysuit, a second formed a jacket, and the V formed their helmets.

Standing before the civilians, Pro Heroes, and Neo Zangyack were the Pirate Sentai themselves.

Gokai Red: Gokai Red!

Gokai Blue: Gokai Blue!

Gokai Green: Gokai Green!

Gokai Yellow: Gokai Yellow!

Gokai Pink: Gokai Pink!

A flag with the crest of the Gokaigers fluttered behind them as they all got ready.

Gokai Red: Kaizoku Sentai!

Gokaigers: Gokaiger!

Everyone's eyes widen to the teenagers' transformation, more so for Sword Shark Mask who looks both angry and scared as he points his sword at the Gokaigers.

Sword Shark Mask: I thought the Sentai Teams were long dead! Where did you come from?!

Gokai Red: As Pirates we collect treasure, the greatest in our possession is Earth's greatest treasure! The Legacy of the Super Sentai! As long as we're alive, they're will to protect this planet will never fade away!

Sword Shark Mask became furious and then pointed his Naginata at the Gokaigers.

Sword Shark Mask: Gormins, kill them!

The Gormin Sailors raised their rifles and charged at the Gokaigers who all pulled out a sword and gun.

Gokai Red: Let's make this showy!

Gokaigers: Aye, Aye, Captain!

The Gokaigers then charged at the Gormin Sailors and the battle of Earth began. The first to attack were Gokai Blue and Gokai Green.

Gokai Blue: Time to put my training to use!

Gokai Green: I have your back, Benjiro!

Gokai Blue charges in at the Gormin and raises his Gokai Saber up and swings it down on the Gormin's chest slicing the soldier which Gokai Blue then sees one of the soldiers ready to fire but quickly raises his Gokai Gun and pulls the trigger hitting the soldier in the head and collapsing to the ground. Gokai Blue looked a bit surprised that his attacks actually were effective but with him distracted two Gormin Sailors were about to flank him until Gokai Green appeared in front of them and slashed the two of them across the chest. Gokai Green then aims the Gokai Gun and fires it which the laser manages to hit four of the Gormins taking them out.

Gokai Green: I suggest you remember what you said back on the roof.

Gokai Blue: Sorry, I know Izuku now come on!

Gokai Blue and Gokai Green continued to fight together, taking down any Gormin Sailors in their way. As the two continued to attack, Gokai Yellow and Gokai Pink were seen surrounded by the Sailors.

Gokai Yellow: Blondie, are you ready to test these babies out?

Gokai Pink: Try and keep up support class girl!

Gokai Pink twirled around two Gormins that attempted to strike her with their rifles before slashing them twice across the back with her Gokai Saber. Gokai Pink then took aim with her Gokai Gun before firing three laser bullets, each hitting a Gormin in the head, causing them to collapse. While Gokai Pink continued her attack Gokai Yellow started using her new babies and fired the Gokai Gun several time manging to hit three sailors making her giggle as she was enjoying using her knew babies but as she kept firing a Gormin Sailor manages to get behind Gokai Yellow ready to hit her but seeing the Gokai Saber's reflection quickly dodges the attack and does an upwards swipe slicing the Gormin Sailor.

Gokai Yellow: Best day of my life! I love my new babies~

Gokai Pink: Wait, where did Captain go? He isn't with us, and I don't see him with Izuku or Ben-Chan.

Suddenly an explosion was heard and the other Gokaigers turned to see Sword Shark Mask attacking Gokai Red who was easily dodging the monster's attack.

Sword Shark Mask: You are an irritating pest!

Gokai Red: I was hoping you would at least put up a better fight then your grunts, talk about boring!

Gokai Red blocked Sword Shark Mask's Naginata before swiftly kicking the monster in the gut. Gokai Red aimed his Gokai Gun before firing two lasers into the monster's chest, causing it to stumble back further. Gokai Red then backflipped over four Gormins that attempted to attack him from behind. The Captain then swiftly slashed the foot soldiers twice across the back before swiftly whipping around and shooting three more Gormins in the head. Two more Gormins charged at Gokai Red from either side, weapons raised. The Pirate however leaped into the air, causing the two foot soldiers to run into each other. Gokai Red then landed on the ground before shooting the two downed Gormins with his Gokai Gun.

The Civilians and Pro Heroes, all looked in awe as these costumed heroes were taking down the alien threat like it was a cakewalk.

Kamui Woods: How can these kids fight these aliens so easily?

While the Pro Heroes and Civilians continued to stare, the other Gokaigers regrouped with Gokai Red.

Gokai Blue: Captain, we have them on the ropes. What should we do next?

Gokai Red: Sword Shark Mask won't be as easy to destroy, we should use our secret technique!

The Gokaigers smiled under their helmets and understood.

Gokai Red: Think of the team I told you about, then press the button on your belt buckles. Everything will fall into place.

The Gokaigers all pressed the buttons on their belt buckles as they spun around revealing a new set of Ranger Keys. The Gokaigers folded them in half before holding them out in front of them.

Gokaigers: Gokai Change!

The Gokaigers inserted them into the Mobilates before turning them as the top half unfolded.

Mobilates: Gorenger!

Symbols appeared over the Gokaigers as they spun around. As they spun their suits changed. When they faced forward again they now stood in completely different costumes, these ones with capes and large belts.

Gokai Red: Akarenger!

Gokai Blue: Aorenger!

Gokai Yellow: Kirenger!

Gokai Pink: Momorenger!

Gokai Green: Midorenger!

All five then sunk into a group pose.

Gokai Red: Together we are Himitsu Sentai!

Gokaigers: Gorenger!

Everyone looked shocked seeing the Gokaigers transformed once again.

Death Arms: They transformed again?!

Sword Shark Mask: Gorengers....after over one hundred years of waiting I will finally have my revenge!

Gokai Red: We'll see about that, you now face Earth's first team of heroes! You lost to them once back in the seventies and history tends to repeat itself you know!

Sword Shark Mask became enraged then raised his naginata and charged at the Sentai.

Gokai Red: Gorengers, let's make this extra showy!

Gorengers: You got it!

Gokai Red lunged forward first as Sword Shark Mask swung his naginata down at him, the red leader caught the blade between his hands as Gokai Blue and Gokai Green ran up behind him. Gokai Blue and Gokai Green both spin around on the heels of their left legs before delivering a swift double kick to the monster's head. Gokai Yellow and Gokai Pink both rush in afterwards, reeling back their left fists before delivering a double punch to the Sword Shark Mask's gut, causing him to stumble backwards. Gokai Red then charges forward, front flipping over the monster before landing on the ground behind him. In one swift motion Gokai Red whips around and delivers a roundhouse kick to the monster's head, sending it sprawling across the ground.

Sword Shark Mask: This cannot be happening again! I refuse to lose to the likes of you a second time!

Gokai Red: As I said history repeats itself, Gokai Pink, would you kindly?

Gokai Pink: Gorenger Hurricane!

Gokai Pink held up a multicolored grenade in the shape of a football as all the Gorengers scattered around Sword Shark Mask.

Gokai Pink: Izuku!

Gokai Pink tossed it to Gokai Green who swiftly kicked it higher into the air towards Gokai Yellow.

Gokai Green: Mei, heads up!

Gokai Yellow then struck it like a volleyball as it flew towards Gokai Blue.

Gokai Yellow: You're up Blue!

Gokai Blue caught the ball, holding it out in front of him.

Gokai Blue: Captain, you are all set!

Gokai Red ran towards Gokai Blue before leaping into the air and delivering a flying kick to the ball. The ball flew towards Sword Shark Mask before it transformed into a large sushi knife that slices the monster clean in half, causing him to explode. The Gokaigers all regrouped before reverting back to their original costumes. Everyone looked at the Gokaigers in shock as they defeated the aliens. Everyone was quiet for a moment before starting cheering for them.

Gokai Blue: This is going to be hard to get used to.

Gokai Pink: It's a little strange isn't it? Being cheered for? But it's not a terrible feeling.

Gokai Red: We should set sail, it seems the Neo Zangyack forces have retreated for now so the city should be safe.

The Gokaigers agreed but before they could leave Kamui Woods holding Mountain Lady who was still knocked out and an injured Death Arms walked over to them.

Death Arms: Who are you kids?

Gokai Red: Kaizoku Sentai Gokaiger, we're a pirate crew that fights evil as showy as possible. We also carry the Legacy of the Super Sentai, that's the blanket term for teams like ours.

Kamui Woods: You kids realize that you did something illegal right? As much as you helped the city you broke the law.

Gokai Green: Actually, you are wrong Kamui Woods, the law only applies to quirk individuals.

Gokai Pink: All our abilities are purely physical, all our weapons and powers come from our suits. No quirks needed.

The two Pro Heroes looked shocked hearing that their supposed quirks were just from their suits.

Gokai Blue: You got your answers but we must leave as the Captain is very busy. Time to raise the sail!

Gokai Red: Hold on, you want an explanation right? We're a Sentai Team. The Sentai teams were Earth's heroes before quirks. That other team we turned into, Gorenger? They were the first, they appeared in 1975. You earthlings have a lot of history you forgot about your own planet.

With that the Gokaigers all repelled back up onto the Gokai Galleon before it flew off away from the site of the attack.

Back in U.A

Over in U.A. Nezu and Aizawa were looking at the tv looking at the news of what transpired in the city.

Nezu: It seems that he is on our side but also he is still inexperienced. He is well versed in combat but he could do more. What are your thoughts on it, Aizawa?

Eraser Head: Are you implying that we should consider teaching this punk? Sure he's got skill, but he dragged three standard course students and a support course student into this mess. One of which is related to not one, but two of the pro heroes who teach at this school.

Nezu chuckled and understood where Aizawa was coming from, but he knew too well that if they didn't bring this Marvelous in, they would have more trouble with the alien invaders. Not only that the public would probably turn on them if they tried anything on the students due to their abilities to defeat the aliens.

Nezu: Eraser Head, yes what he did was reckless but in the long run we have to bring him in. We have seen what those kids can do and if we don't bring them into hero courses well we could be having problems with not only the public but also the public hero safety commission. We know well that the commission will try everything in their power to arrest them for their antics but can't because they didn't use their quirks. Also if they did try to go after them heroism, would be put in jeopardy as the public would find Pro Heroes useless and give the notion that heroes aren't needed causing, if not another vigilante era.

Eraser Head: What a pain, okay so we take this pirate kid from space in and have him and those other kids join the Hero Course. I won't argue with your decision Nezu, but if what the punk said is true, those other costumes they changed into belonged to heroes from Earth. That and he said there were multiple of those teams, that means there's an entire era of Heroes we know nothing about. Should we try and find an expert on Quirkless Era myths who might be able to give us more information on these Sentai Teams?

Once Eraser Head was finished speaking, Nezu had a smile on his face which he knew the clever Principal had already had a person in mind.

Nezu: Aizawa we already have an expert in this department. You know him after all he is the only non-hero teacher in this school.

Eraser Head: You mean Kurose? Sure he's a history teacher and has a hobby for researching urban legends, but are you certain he has any information on these Quirkless Era heroes?

Nezu: Trust me, Kurose has what we are looking for. I have seen his work and he has information backing up his claims for the urban myths he discovered from a hundred years ago.

Eraser Head let out a sigh, but ultimately decided to not push the matter further at the moment.

Eraser Head: We're going to have to hold a faculty meeting to discuss this anyway, we could at least invite him and see if he's got anything notable. As for transferring these five into the Hero Course, I'm assuming you have a plan for that?

Nezu gave a devilish smile.

Nezu: I have decided that these five students will be part of Class 1-A and Class 1-B, so there will be no favoritism. So I hope you and Vlad King can whip those students into shape.

Eraser Head: Fantastic, but you better be the one to break the news to All Might and Magnetic about their kid. Or maybe have the pirate kid do it, he dragged those kids into this mess. I swear we're encouraging those kids to fight these aliens. What is the world coming to?

Nezu: A chance of mass genocide to be precise, Aizawa.

Eraser Head just looks at him as if that was a rhetorical question.

Eraser Head: Okay, I'm going to pretend I didn't hear that. So should we hold the meeting soon? I hope at the very least those kids convince that pirate to bring them back to the academy so we can corner him.

Nezu: Hopefully, my theory is that they are going to ask their captain to come with them so they can ease tension for what they just did. The meeting will be held tomorrow as we need to get this under control. Thankfully tomorrow is Saturday so everyone will show up. Besides that, the Sports Festival will have to continue so that the public won't lose morale.

Eraser Head pinched the bridge of his nose, but nodded his in agreement.

Eraser Head: As much as I hate to admit it, they did pretty well for rookies. The public had lost all hope, but the moment they got to work it was like it was never lost to begin with. It's strange, that pirate kid talked about making it "showy", yet when all was said and done, he didn't bother to stick around for the media.

Nezu: It seems he shares the qualities of just doing his job, nothing more and nothing less. It's very rare to see that in people. Most would bathe in glory, but not him. It seems we have found a diamond in the rough. Now I will inform the other heroes as I have a long conversation ahead of me.

Eraser Head: I just hope this whole thing goes smoothly. The less headaches the better.

Nezu agreed and Eraser Head headed out of the room leaving the Chimera alone in his office.

Nezu: New players have been brought onto the board. We have not only the League of Villains to worry about but also an alien emperor wanting to take over our planet. This does not bode well. However, not all hope is lost.

Nezu then pulls out his phone and then dials a number.

Nezu: Toshinori we need to talk....
