Ch.2 Tragedy Strikes and Douglas' Imprisonment!
One year later in a street.
Izuku/Douglas, Buggy, and Shanks were walking in the street talking about events.
"So, Douglas how's your 'wife' and 'daughter'?" Shanks (13-year-old) teased.
"Yeah, how is the little unicorn?" Buggy (13 years old) asked
"Both are great guys. But you two lived in the same house as me!? So why are you asking?" Izuku/Douglas (10 years old) said
"Just making a conversation man," Shanks said
"Well in few years we'll be making names on our own with the crews Shanks and I made," Buggy said
"Yeah, I'm going to miss you guys," Izuku/Douglas said sadly
"I know but don't let that worry you," Shanks said as he put his hand on Izuku's hair.
"Yeah, we may be separated and we may not be blood-related but we are brothers and rivals to the end!" Buggy said
"Yeah, and I am going to be a hero that everyone looks up to like All Might!" Izuku/Douglas exclaimed as he declared his dream.
Shanks and Buggy chuckle at Izuku's dream.
"So, Shanks how's Makino and Buggy how's Alvida?" Izuku/Douglas asked
The two blushed at the very names.
"See you two teased me for my crush but you two don't have the guts to asked them out for once!" Izuku/Douglas yelled
As they were about to produce a well-thought counter argument or in this case a street brawl with the winner being right.
Just then...
BOOM!
"What was that?!" Buggy yelled
"I don't know!" Shanks yelled
"This is not some two-bit villain it must be someone really strong!" Izuku/Douglas said
Then Shanks used his Observation Haki to detected the chaos.
"I sense...your DAD! He's near the center of this power!" Shanks yelled
"Daddy?" Izuku/Douglas said with worry.
"Come on!" Buggy yelled
As the three ran the destruction became worst and worst they also helped many of those who got caught and the survivors helped other survivors.
"Who could have done this?" Izuku asked in awe at the destruction and the dead bodies of heroes and civilians.
The three heard two more people in pain and the three ran to the source.
"AAAARRRGGGHHH!" Hisashi/Scopper yelled in pain with several burns, cuts, and a bleeding scalp.
"COUGH!" A blond and buff man coughed as he has a bleeding stomach from a very sinister enemy.
"Hey, are you two alright?!" Buggy asked
"Ugh...I'm alright but Scopper he's injured..." the man said
"Hey I may be down but I'm not out yet All Might," Hisashi/Scopper said
"You're ALL MIGHT?! What happened?!" The three yelled
"It's a long story but your father infiltrated a group and has found plans within the next five years by a very evil man..." All Might said
"I manage to put it all on a flash drive all I need is a few seconds to transport the thumb drive to the police," Hisashi explained
"We'll help!" Izuku/Douglas exclaims
"What? But you're just a kid..." All Might said
"Yeah? He was a part of the Roger pirates as a cabin boy he'll be alright, just like me and the other two boys," Hisashi said
"What? But I thought..." All Might asked
"We'll explain later but right now people are in need of help," Hisashi said
But then...
"Well, how can you help anyone if you can't help yourselves?" A villain said who came out of nowhere.
"ALL FOR ONE!" All Might yelled
"Now fall...Symbol of Peace..." AFO attacked with multiple quirks but was blocked by Douglas' machine arm which he made out of broken vehicles.
"Impressive quirk kid, who are you?" AFO asked
"I'm Douglas Bullet the "Demon Heir" and it's not a quirk it's a Devil Fruit!" Izuku/Douglas said as he got into fighting position.
"Devil fruit? What a bothersome bunch of quirkless rejects," AFO sneered but Buggy got to his blindside.
" Well, this quirkless reject is about to get you! Now take THIS my special MUGGY BALL! And blow up!" Buggy yelled as a tiny ball Fired from the bottom of his shoe and blow up in his face.
"Way a go Buggy! You got him good!" Shanks said cheer way too soon.
"Don't lower your guard! If he is able to injure All Might then he must be very strong!" Izuku/Douglas said
"You should listen to your friend I'm one of the strongest men you'll ever meet," AFO boasted.
As AFO stands as if it didn't hurt him at all.
"Well, that was unexpected. Now I remember you. You four guys appeared I the news a few years back when that loser Gold Roger was alive," AFO sneered
With those words, the four former Roger pirates stood in silence but it was Izuku was the one to break the silence.
"Take it back..." Izuku/Douglas said as his hair covered his eyes.
"What? Take What back all I said was the truth," AFO said
"Buggy...Shanks...take my father and run..." Izuku/Douglas said as his eyes turned red.
"Right come, old man, we need to run," Buggy said
"Good luck Douglas," Shanks said
"All Might make sure my son is still alive; if he's not I'm going to kill you..." Hisashi/Scopper said as he threatened All Might.
"Sure I will..." All Might said
As the three warped away with Hisashi/Scopper's DF.
" You will regret those words about my captain," Izuku/Douglas said with venom as Conquer's Haki covered his body.
"Is this the power of a former Roger pirate?!" All Might thought
"So this is a cabin boy from THAT man the scars burn from that man but there is no way a cabin boy could be THAT strong," AFO thought
"Yawn lets do this thing... COUGHS!" AFO said but was punched in the stomach by Izuku!
"Im-impossible!" AFO yelled in pain.
"Now let's do this thing!" Izuku/Douglas yelled
Timeskip
Izuku/Douglas's giant robot broken and Izuku/Douglas breathed heavily as All Might punched AFO.
This gave Izuku/Douglas the chance to wound him with a critical attack.
Izuku/Douglas then punched AFO in the chest with a Haki laced punch and then All Might defeated All For One with United States of America Smash. But All For One's body was warped away by some purple smoke.
"Damn he got away but we won...ugh..." All Might said as he felled to his knees then fainted by the blood loss and lack of energy.
"Alright time for me to run," Izuku/Douglas said as he was just limping away.
But then...
"Hold it! Scum!" Yelled a red suit man with a marine hat.
"Well, if it isn't Vice Admiral Akainu or is it Admiral Akainu these days. What do I owe the pleasure?" Izuku/Douglas said sarcastically.
"I saw the whole fight and I'm rather impressed but you under arrest for various crimes against the World Government," Akainu said
"Not surprising," Izuku/Douglas said coldly
"But your worst crime is injuring the number #1 hero All Might!" Akainu sneered
"What?! But I didn't..." Izuku/Douglas said
"And so with the authority of the World Government, you have been sentenced life in Level 6 of Impel Down. And don't try to run our new "toys" are unstoppable," Akainu said
"New toys HA! You government dogs your fancy little machines don't scare me!" Izuku/Douglas said
"I know but this one is going to revolutionize everything meet PX-1," Akainu said as a man came out and began to charged his laser.
"What?...but that's...Kuma...and that's Kizaru's...what the hell are YOU?!" Izuku/Douglas yelled as he prepared to fight back as a shot was fired.
CLANK!CLANK! BOOM!
PEW!
BOOM!
CLANK! CLANK!
PEW! PEW! PEW!
BBOOOOOMMMMM!
Timeskip
At the Uraraka home
With Ochako, Kastuki, and Eri watching tv playing Cubix Robots for Everyone.
"You know I love our little 'granddaughter'," Inko said
"Yeah, Kastuki is actually becoming nicer to everyone since Eri came," Mitsuki said as she is happy that Kastuki is being nice to everyone in hope to make Eri happy.
"And Ochako wants to be a hero for her parents and for little Deku's daughter. I hope this will last for a long time," Ochako s mom said
Unknownst to her everything will change as a portal opened up.
SLAM!
CRASH!
BONK!
As Hisashi, Buggy, and Shanks came out from the portal... but no Izuku.
"Honey! Where's Izuku?!" Inko yelled as she ran to her husband while treating his injuries.
"Ugh..." Hisashi/Scopper groaned as he still has the thumb drive in hand.
"We don't know," Buggy groaned
"Yeah, I hope he's alright," Shanks said
As the screen on the tv switch from the show to a news report.
"We interrupt this program for breaking news Izuku Midoriya or Douglas Bullet of the Roger Pirates was caught by marine Admiral Akainu," a news reporter said
"No..." everyone thought with wide eyes as everyone went to the tv.
"We just received reports of the destruction caused by Izuku Midoryia or Douglas Bullet for reason for targeting All Might but failed as "Red Dog" Akainu intercepted Douglas Bullet. The Demon Heir will be sentenced to Impel Down for life..." the news reporter said
"That's BULL!" Shanks yelled
"Those jerks!" Buggy said
"NOOO!" Inko screamed
"Izuku..." Hisashi/Scopper said
"Deku..." Kastuki said
"WAAAHHHH!" Eri cries
"Don't worry mommy's here..." Ochako held Eri and rock her but she was crying herself and her heart was broken since she will never see Deku ever again.
Meanwhile in a hospital
"Ugh..." All Might groaned
"Looks like you're awake Toshinori," a small old man said
"Sensei Torino, what happened?" All Might asked
"You fought All For One but he got away," Torino said
"Yeah, if that kid wasn't there I would have been 6 feet under," All Might said
"What kid?" Torino asked
"The green haired kid, where is he?" All Might asked
"Umm... I can explain that," a detective said as he entered the room.
"Oh, Detective Naomasa Tsukauchi what do you mean?" All Might asked
"He's...he's been sentenced to Impel Down on the charges of accomplice to All For One and for being a Roger Pirate," Naomasa said as he regrets saying those cursed words.
"What?!" All Might exclaims
Meanwhile in Wano in Bermuda Triangle
"So, Oden when will you asked out Toki? Come on we known you like her," Kaido teased as Oden blushed but made an excuse.
"Teased me again and I will spoil what Raftel is like," Oden threatened Kaido
"NO! I WANT TO FIND OUT MYSELF!" Kaido yelled as he covered his ears.
"Come on Kaido we don't have time for this. I want to know what Orochi is planning?" Oden said as he changed the subject.
"Lord Oden! Sir Kaido! It's terrible!" yelled a message as Kaido took the newspapers.
"What is it?" Oden said
"It's about your crew," the message boy said as he spoke to Oden.
"Oh, how are they doing?" Oden asked
"Umm... is one of them named Douglas Bullet?" Kaido asked
"Yes, why?" Oden said
"Then he may have a very bad day," Kaido said as he gave Oden the papers.
"...WHAT?!" Oden yelled as he read the papers.
Meanwhile in Zunesha/Zou
"Douglas not you too!" Pedro cries for his lost friend.
In Impel Down Level 6
"Move it Douglas this is your special cage for your crimes against heroes I hope you die MONSTER," the Guard said as Izuku hands were shackled with heavy weights and now wears an extremely heavy Super Wapometal a metal alloy with is several times stronger and heavier than normal Wapometal.
"Heh heh heh heh...fresh meat!" the other prisoners laughs manically.
"Well, well if it isn't Douglas Bullet what are you in for?" Shiki asked
"..." Izuku/Douglas in silence as he is broken.
"Uh...Kid any answer hello?" Shiki said with a worried tone.
"Aw man, I didn't think they broke this kid I actually like this kid," Shiki thought.
"...Nothing..." Izuku/Douglas said
"?" Shiki questions this but decides to put it in the back of his mind and plans his escape.
