Ch.11 Hero Killer Stain and the Legendary Origin Parameica DF.

Several days have passed and Izuku is training with Gran Torino about training One for All, while Ochcako is practicing martial art with Gunhead, Kaido is also training by fighting "The Sea Roar" Scratchman Apoo, "Red Flag" Diez Drake, and Basil Hawkins "The Magician", and finally Eri is with Vivi and her 7-year-old daughter Vivian who are playing together. Izuku even saw some from his class and one from 1-B.

Later Achilles called out everyone that the interns will go to Hosu.

"All right everyone now it's time for you kids to patrol and hunt some villains and Drake you go with my son. Oh, and take one of the solar sail lifeboats." Achilles stated as he held some of the world's most evil thing more "evil" than himself "Paperwork".

"Okay, everyone you heard the Captain we leave now," Drake commanded

"Okay, Eri your mother and I will be back before you know it." Izuku comforts her.

"Yeah Deku Badguy and I will be back!" Ochako stated

"Promise?" Eri asked as she tilted her head.

"Promise," Ochako and Izuku said.

"Come on! Guys we're leaving for Hosu!" Kaido yelled.

Izuku and Ochcako left with Kaido, Drake, Gunhead, and Gran Torino and landed at Gran Torino's house then took a train to Hosu district.

At another location Stain, Kurogiri, and Tomura appeared and Stain starts his killing spree as the two send out multiple Nomus.

Later, at the train, a nomu came in and starting to attack at random. So Izuku uses the Junkyard to shoot flames at the nomu. Then Kaido charged and knock the nomu out of the train.

"KAIDO!" everyone yelled as they were not expecting Kaido to ram the nomu.

"Don't worry I'll be back!" Kaido yelled as Izuku followed and look out of the window and saw the madness. And then Izuku followed the madness and everyone yelled for him.

"DEKU!/ PORTGAS!/ BADGUY!" Everyone yelled even Drake as they jumped off the train to follow Izuku. As Gran Torino started to fight a nomu which headed for civilians Endeavor with Shoto came with a joint fire attack. And Drake who turns into an Allosaurus to bite the nomu. Izuku overheard Manual the hero that Tenya was working with is missing and Izuku realized that Hero Killer Stain is here in Hosu so Izuku, Ochcako, and Kaido went to find Tenya.

Meanwhile with Tenya found Stain who about to kill the hero Native. Stain quickly defeated Tenya and said that he is a fake hero. Tenya said that his brother is his hero and he will get revenge. Stain rebutted with his answer to save Native first since a hero always thinks about themselves second the victim or hostage first. Tenya realizes this and Stain was about to kill him but Izuku kicked him in the face. The talk was the same in manga/anime. Then Shoto appeared out of nowhere and attacked with his left side followed by Kaido and Ochcako all of them attack at the same time.

"Ochcako! Go get help! A swordsman more specific!" Izuku yelled as Ochcako ran away and yelling that her boyfriend will be all right.

As they all about to fight Stain ask why are they here?

"Because...it's the job of a hero to meddle in other people's business! And beside Tenya is our friend!" Izuku answered.

"YEAH! We either fight together or fall together! WIND TUNNEL!" Kaido responded as a light wind attack came from his palm hit Stain as Izuku used that to save Native and Tenya. But Stain was able to cut Izuku and Kaido on the cheek and drank their blood Izuku froze while Kaido was fine which confused Stain for a second.

"EARTH HYDRA!" Kaido yelled as a hydra head crashes towards Stain but he dodges it.

And Kaido sends another attack.

"BONE HYDRA!" Kaido yelled as another hydra head made of bones scratched Stain's leg.

Izuku then realizes Stain's quirk the power to paralyze those with different blood type. The event happens the same except for one thing.

"Wait a minute if the kid is right why aren't you affected?" Stain asked Kaido

"HEH...HEHEHEHE...HAHAHAHA! I ate the second most powerful Logia devil fruit the Blood blood fruit! That means I am all types of blood and completely weaponize it! Watch this!" Kaido laughs manically as a sword made of frozen blood made from his hand which he cut with his sword imagine Ichigo's Sword when it first appeared and clash with Stain.

As the two were trading sword slashes.

Just then...

"One sword style...3,600 Caliber Phoenix!" Ryuma yelled as a slash attack came out of nowhere behind Stain but he dodges it as well everyone else.

"Ryuma!" Izuku, Kaido, and Tenya yelled at their friend.

"DEKU!" Ochako yelled behind Izuku with Hawkeye Mihawk?!

"Ochcako? And Hawkeye?! Here?!" Izuku was shocked while Ochcako hugged him then saw Ryuma shocked and confused.

"Ryuma! How you got here so quickly?!" Ochako asked

"I took a shortcut duh." Ryuma replied

"Heh unlike your father who gets lost the minute you look away." Kaido sneered while Ryuma doesn't deny it and charged at Stain.

Meanwhile at the Roronoa Household

"ACHOO!" Zoro sneezed

"Bless you that means someone is talking about you," Tashigi said

"It better not be Dart brow," Zoro grumbled.

Back with Izuku and Co.

After crossing swords (like in Bleach) with Stain both decide to finish the fight.

"One sword style: Back end...LION STRIKE!/ DIE DEMON!" Ryuma and Stain yelled as Stain fell on his knees weaken and shocked that he is not dead.

Afterwards, heroes found us and took Stain in until something happen as a winged Nomu caught me.

"Huh? HELP!" Izuku yelled dangling from the nomu.

"DEKU! BADGUY! MIDORIYA!" everyone yelled as some blood landed on Ochcako's cheek as that happen Stain broke free licked the blood off her which was the nomu's blood which froze the nomu then Stain killed the nomu. Endeavor, Gran Torino, Drake and everyone else was ready to attack. Until Stain said something unforgettable.

"HEROES THAT TITLE IS FORGOTTEN! HEROES A TITLE THAT IS BEING MISUSED! HEROES! ONLY ONE MAN AND CREW THAT ARE WORTHY! ALL MIGHT! STRAWHAT!" as Stain finish his sentence that made almost everyone froze with fear...Almost everyone except Hawkeye, Ryuma, Kaido, Izuku, and Drake and what they said shocked Stain to his core.

"So... bring it! The Era of Heroes is over this Era belongs to Pirates FOREVER MORE!" Kaido stated

"Stain, he is right not everyone will have good intentions but that is why my grandfather created the Great Pirate Era to show their true colors in this war-torn world." as Izuku said that Stain fainted on his feet but before he fainted he thought.

'…He's right…' Stain thought

Later after Stain was taken in and Izuku, Ryuma, Kaido, Shoto, and Tenya were put into a hospital.

In the room, there was Gran Torino, Drake, Gunhead, Ochcako, Endeavor, Manual and nope Hawkeye isn't here...wait I'm wrong he's in the corner.

"Well, guys we have been in this hospital since yesterday you would think someone would scold us," Kaido stated but just at that moment Shoto's sister came through the door.

"Uh...Fuyumi what are you doing here?" Shouto asked.

"Is Tenya here?" Fuyumi asked

"Uh...I am present." Tenya replied as he did Fuyumi hit Tenya and Shouto with a frying pan?!

"YOU IDIOTS! WHY DID YOU TWO DID THAT?! HUH?!" Fuyumi yelled which shark teeth which shocked everyone even Endeavor.

"We're sorry but why you hit me?!" Tenya asked with a HUGE bump on his head.

"Because I'M DATING YOUR OLDER BROTHER SO OF COURSE I'M MAD AND WORRIED!" Fuyumi yelled.

"WHAT?!" EVERYONE YELLED even Shouto except for Mihawk.

"Uh...Dad, did you know?" Shoto asked Endeavor.

"Uh...No I didn't even know she is dating I still need to process this." Endeavor said as his mind was blown.

Later the Chief of Police of the Hosu came who is a man with a dog for a head the rest happen as same in the manga/anime, but the real news still travels through the underworld and the World Economic Journal.

In the Pirate Ship, Rising Pluto word of Hero killer Stain vs Kaido and Izuku spread like wildfire. Eri is worried about her father getting hurt.

Eri notices a strange fruit which has swirls and has two different colors. And asked a newbie Michael J. Caboose to help her cook it and give to her father as a get-well gift.

Later Eri visited the Hospital.

"Papa! Mama!" Eri yelled as she ran up to her dad and mom.

"Hey, Eri I'm okay just like I promise," Izuku stated

"So, Eri what's in the bag?" Ochako asked

"Oh, I made Papa a mystery fruit meat pie," Eri explains as she took out the pie.

"Oh, thanks Eri." as Izuku took the pie and ate it while the pie was terrible, and he felt he was going to barf.

"Did you not like it?" Eri asked

"No, I love it but was in it?" Izuku asked

"Umm pies stuff, meat, this weird fruit..." Eri listed the ingredients until Kaido said.

"Wait what did the fruit look like?" Kaido asked as he worried.

"It has swirls and has orange and aqua coloring?" Eri tilting her head.

"And did you taste the pie or fruit?" Kaido asked

"No, I made sure Papa get the first taste! Why?" Eri asked

Kaido pales then he said. "BADGUY! YOU JUST ATE A DEVIL FRUIT!" Kaido yelled

"WHAT!? WHICH ONE?!" Izuku yelled/asked

"It's the one my dad found very recently the last unclaimed Original DF. The Alchemy Alchemy fruit the first Paramecia. You have powers of alchemy without a philsolsor stone!" Kaido explains

"NOOOOOO IT CAN'T BE!" Izuku yelled.

"Wait what so important about this one?" Ochako asked

"Okay let me explained there are devil fruit types right?" Kaido said

"Yes, I remember," Ochako said

"Yes, but there are three original Devil Fruits. The First Logia DF is the Disaster Disaster fruit the power of all logias and the tremor tremor fruit which my dad ate. Then there is the Kaiju Kaiju Fruit the first Zoan DF which I ate, and finally The Alchemy Alchemy fruit the first Paramecia type Deku here ate," Kaido explained

"Oh, but wait does that mean you can't swim anymore?!" Ochako yelled

"Yep, but that is the least of my problem now that all three Origin DF are found we'll have targets on our backs for having these powers," Izuku said

"Yeah everyone will literally kill for any of the Origin DFs, like Blackbeard," Kaido said as Eri and Ochako looked worried.

Meanwhile, in a bar two men are talking about the lateness video about Stain and villains are gathering all of the scenes are the same except Muscular pulling a chain which led to his slave Himiko Toga daughter of Massacre Soldier Killer. Followed by Don Krieg, Ice Demon Mira, and Time Witch Towa.

"….Kaido…," Himiko said as she shed a tear.
