Continued story summary:

*Warning* This will be a multiple crossover story featuring characters from One Piece and the Elemental Nations. If that's not your cup of tea, then you should skip it.

Katsuki is different in this story, yes he is a bully in the anime but he is not in my story. Instead of people expecting great things from him he is ostracized because people fear his quirk. Izuku getting a devil fruit ability, made it so they were on equal footing from a young age. Katsuki never developed the hatred he has for Izuku as he did in the anime.

So without further ado...

Chapter 1: The Meeting

Summary:

Izuku and Katsuki are at Dagobah beach, Izuku finds fruit and eats it. Later he finds 3 people washed up onshore. he finds out that the fruit he ate allows him to heal the strangers.

Izuku and Katsuki are walking to the beach near their homes. Katsuki received his Quirk yesterday while protecting Izuku from older bullies. Katsuki wanted to show off his quirk to his friend so they go to the beach to practice.

"Come on, Nerd." Katsuki huffs impatiently.

"Kacchan, I can see the beach."

"Let's go, I wanna show you my awesome quirk."

The boys arrive at the beach, which is filled with decades worth of trash that has washed up onshore. Katsuki smirks 'This is perfect, I can definitely show off my quirk by exploding the trash around here.'

" Let's go over to one of these trash piles so I can practice blowing shit up." Katsuki doesn't wait for a response, feeling excited he starts exploding the random trash.

"Kacchan is awesome. That's the coolest quirk ever." Izuku is cheering Katsuki on.

" Of course, it is, I'm gonna be better than All Might."

With stars in his eyes, he nods enthusiastically. Completely focused on Katsuki he watches the smoke clearing. From his place on top of a mountain of trash, he notices a strange glow coming from the other side of the trash. Being the ever-curious five-year-old he is, he goes to investigate. He scuttles off the trash heap he's sitting on and follows the strange glow. When he reaches the small object, he notices a small Kiwi-looking fruit. He doesn't notice anything wrong with it, sure it looks a little strange but he hungry. He picks up the fruit and rinses it off in the water and takes a bite. It's bitter as he shallows. He drops the fruit and notices his arm is on fire.

" AHHHHHH" Izuku Screams immediately snatching Katsuki's attention.

Katsuki follows the screams and sees Izuku standing there with his arm on fire. Katsuki starts to feel guilty thinking he hurt Izuku he runs over to try to help him and notices the fire is green. 'That's not the color of the fire my explosions make. That's strange the fire doesn't seem to be causing him pain. It doesn't feel hot either. Could this be his quirk?"

"Oi Nerd" Katsuki starts. Still, in full panic mode, Izuku doesn't respond. "Listen to me Nerd!" Katsuki shouts while hitting Izuku on the head.

"Owwww Kacchan, why did you hit me?" Izuku whines.

"Tch. I was knocking some sense into you. You idiot. Look the fire is green and doesn't look like its burning you. Do you feel any pain?"

"Huh... um sorry, Kacchan... um now that you mention it no, I don't feel any pain. It is a little warm but not uncomfortable."

"Could this be your quirk?"

Shifting from foot to foot, Izuku starts mumbling "um no I don't think so, remember my mom brought me to the doctors they said I didn't have the mutation to have a quirk. I don't think this is a quirk... I umm ate a fruit I found here it looked so good, but it was really bitter"

"Oi Nerd" Katsuki looks confused. "You said something about a fruit"

"Yea"

"What does fruit have to do with you being on fire? huh?"

"I don't know I took a bite, then my arm burst into flames"

"That's bullshit I've never heard of a fruit that does that. What did it look like?"

"Umm like a kiwi but not a kiwi?"

"Hummmm. Well, let's test it" Katsuki shoots Izuku a feral grin.

"What, Kacchan what if I hurt you, or can't stop myself from being on fire? I don't even know what it does! I'll never forgive myself if I hurt you Kacchan."

"It doesn't matter. Are you calling me weak?!"

"Sorry Kacchan, you're the strongest person I know" Izuku pouts and thinks over testing this new ability. Coming to a decision he looks at Katsuki with determination "OK let's practice but you'll stop me if I lose control, right?"

"Of Course, Nerd"

The boys move to a secluded part of the beach. Approaching a clearing by the water Izuku sees three people lying face down on the beach. He looks a little longer and notices they appear to be hurt.

"Kacchan, wait there are people"

"So? Who cares? we will just move farther down."

Izuku stops walking and stares at the people on the beach. "But Kacchan I think they might be hurt. Let's help them." Izuku runs off.

Katsuki releases a sigh and jogs to catch up. Upon reaching the strangers Izuku notices a man and two kids around his age laying in the sand. He approaches cautiously until he is close enough to tap the man. "Hey sir, are you ok?" The man lets out a pained groan but otherwise doesn't move or speak. Izuku tries to wake up the boys but they both let out weak pained moans.

"Let's flip them over"

Katsuki helps Izuku flip over the man and then they each flip over one of the boys. Getting a good look at the man's face they notice three gashes across the man's eye. Inspecting the man for more injuries Izuku notices his left arm is severely damaged. Katsuki inspects the two boys only noticing a couple of minor scrapes and bruises. Izuku kneels next to the older male and closes his eyes he put one hand on the guy's arm and the other hand over the guy's eye. He focuses on his flames. Katsuki watches mesmerized as Izuku closes his eyes and watches as the green flames transfer and dance along the man's injuries. He is about to stop Izuku when the flames die down and the bleeding stops. The man releases a relieved sigh and his breathing evens out and looks peaceful.

"Wow" Katsuki states breathlessly

Izuku opens his eyes and sees the damage is mostly healed he smiles and looks at Katsuki "Kacchan, I think my fire heals"

Still, in awe Katsuki looks at Izuku "That was incredible Izuku, that explains why your flames did seem hot"

Izuku gives Katsuki a beaming smile and moves on to the other boys putting one hand on each of the boy's chests and closes his eyes. this time he focuses on the same feeling that he felt healing the other man. He feels the warmth of his flames moving to the chest of the two boys he focuses on healing the minor scrapes and bruise. He is also directing the water out from their lungs. The two boys start coughing out globs of water, Izuku and Katsuki turn the boys on the sides so they can spit out the water.

"Kacchan, I can't believe I healed them, what should we do now?"

" They should be fine, but maybe we should wait until they wake up".

"Yea your right. We should go wait for them over there " Izuku points to the group of rocks off to the side. They make their way over in silence thinking about what happened today. "Hey Kacchan" Izuku questions while looking at his hands.

"What? Nerd"

"Ummm this new power is great huh?"

Katsuki looks over to Izuku and hums. Yeah what of it, mine is still better"

"Remember when the doctors told me I'll never have a quirk and I still wanted to be a hero... You said that no matter what we will be heroes together and we will be the best team of heroes ever?"

"Yeah"

"Can I be honest with you, and promise you won't get mad at me?"

"What is it?"

"Well, I didn't think I could ever stand by your side as a hero anymore. I wanted to support you, give you pointers on your costume, and help design support items for your quirk. I have a whole notebook written out on ideas. I guess now that I can heal with my flames now, I feel I can stand beside you at the top."

"Why didn't you mention this before idiot?"

"Kacchan you're my only friend and my best friend I didn't want to burden you with my thoughts. I'm sorry Kacchan"

"Hey nerd, we are gonna be the greatest heroes ever just you wait. With your new power, we will be unstoppable"

"Thanks, Kacchan"

"SHANKS" Katsuki and Izuku are interrupted by a scream. They look over and see one of the boys is screaming. Izuku jumps off the rocks and runs over to the boy. Katsuki follows and a slower pace.

"Hey!" Izuku calls out happily that the boy is awake. The boy looks up eyes wide with wild fear. Izuku approaches slowly with his hands poised in a non-threatening manner. "Hey, my name is Izuku, and this is Katsuki. We found you here can you tell us your name?"

The boy doesn't respond, he is looking worriedly at the older man with silent tears rolling down his cheeks. Izuku notices this and smiles softly "He will be fine; he is only sleeping" The boy looks at him suspiciously "How do you know?" Izuku hears this and focuses on the green flame in him, he summons a small green flame at the palm of his hand. Katsuki finds a piece of glass by his feet picks it up and slices his hand. " I healed him" to demonstrate Izuku takes Katsuki's hand and hovers the flame above the cut. After a few moments, the cut is gone.

"So, you really healed Shanks?"

"Yea, I healed all three of you. What happened if you don't mind me asking? umm, what's your name?

The boy stands up and bounds over to the two other boys, he puts his hand out like a shake "I'm Luffy" with a beaming smile that rivals Izuku's. He looks over to Katsuki "Umm Can I see your hand?"

"Katsuki, sure" he shows him the hand and watches as Luffy inspects it. Luffy's smile widens and he looks relaxed now.

"So, what happened?"

" Umm we were on an island, and people came to hurt me and my brother Ace. Shanks saved us, then we escaped by boat and now we are here"

"I take it that you probably don't wanna go home its doesn't sound safe"

"Well, you are welcome to hang out with us until the others wake up. We will figure out what to do then."

Luffy nods and sits down in front of the two boys. "So that flame is that your Devil Fruit power?"

"What are devil fruits?"

"Um yeah, it's a mystery fruit, I ate one a while ago and now I'm a rubber man. I can stretch and blunt attacks bounce right off." To explain he pulls his cheek out farther than what is possible. "If you eat a devil fruit you lose your ability to swim but he gets an awesome power, I don't much about them myself Shanks might know"

Izuku glances at Katsuki "Come with me to the water. If this power came from the fruit, I think we should test it"

"Good Idea, Nerd"

" I'll come too". Luffy bounces up and down making his way to the water "The water will zap all your strength, so I'll stay behind if you start sinking ill pull you out"

"Ok" Izuku approaches the water nothing happens until he's about waist deep he falls over completely drained and starts sinking. Katsuki uses his explosions to get him close to Izuku and pulls him to shore. Izuku coughs out the water "I guess I ate a Devil Fruit"

"Wow, how come you didn't sink"

"I don't have a devil fruit I have a quirk"

"Quirk?"

"Yeah, I was born with a mutation that 90 % of people have"

"So Cool," Luffy exclaims with stars in his eyes "Join my pirate crew"

"No way, we are gonna be the best hero duo ever"

"Heroes?"

"Yeah, heroes use their powers to save people and protect the people from villains"

"We are going to be the best hero duo team"

"My dream is to be the Pirate King"

"Pirate King?"

"Yea the man that has the most freedom in the world."

"I've never heard of him before"

" Humm ... What part of the East Blue are we?"

"East Blue, I'm not sure where that is but we are in Japan."

"Humm" Luffy thinks as smoke is coming out of his ears. " So, a Mystery huh?"

"LUFFY!" another scream interrupts the conversation. Luffy looks and runs over to the other strangers. Izuku and Katsuki follow close behind. Luffy Launches himself at the other boy and coils his arms and legs around him.

"ACE!" Luffy tackles him in a hug.

Ace grunts as he catches the boy, he looks him over and notices nothing wrong finally he looks over and sees to other boys "hey who the hell are you?"

"Ace, don't be mean they healed us."

"Umm, I'm Izuku and this is Katsuki."

Izuku gently elbows Katsuki "He reminds me of you".

"Nerd! What's that supposed to mean!" Katsuki shouts little explosions popping from his palms.

"Ahhhh. Kacchan. I didn't mean anything bad. He just seems the explosive type." Apparently, this was not the right thing to say as Katsuki literally explodes and Ace combusts.

"Ahh Kacchan"

"Ahh Ace"

During the chaos, the older man starts to stir and lets out a weak groan "Uuugghhhh" Catching Luffy's attention. "Shanks?!" Luffy calls out getting all the boys to settle down.

"Where are we? Luffy? Ace? Are you both ok?" Shanks asks frantically.

"'M fine" Ace grumbles and looks away.

"Izuku healed us" Luffy replies with a beaming grim.

This gets Shanks to open his eyes and he jolts up to a sitting position, immediately he is alert and puts his hand over his sword. As he takes in his surroundings, he notices two young boys, he releases a breath and relaxes and little. "Healed us? Where are we? What part of the East Blue is this? Is there a dock where we can purchase a ship to get us home?"

Izuku steps up "Umm, hi I'm Izuku. I healed you with my power." To demonstrate his summons a small flame on the palm of his hand. "You are in Japan, I'm not sure where the East Blue is but I have a map at home, I'm not sure about any docks here maybe my mom would know."

Shanks widens his eyes with this new information "Japan?"

"Umm Sir?"

"Call me Shanks."

"Umm Shanks, we live about a block away you can come over to look at the map. We will figure this out. You could stay for dinner."

Shanks was about to respectfully decline the offer when two stomach growls sounded off at the mention of food. "Yea, ok that sounds like a good place to start. Thank you."
