Ch. 10

The Demon Heir vs. Part 3

Douglas Bullet vs. Deathstroke, Marines, and Villains

Ochako Joins the Battle! Deku's Powers Awakened to the Next Level!

"UNION ARMADA! ENGAGE!" Izuku/Bullet yelled as his power rebuilds the Kyorge into the mech in the Stampede movie.

As the mech or exo skeleton was made its shadow almost covered the battlefield.

"HERE LIES YOUR GRAVES. NOW STRUGGLE TO THE BITTER END! KAHAHA!" Izuku/Bullet laughs through his Kyorge Catapult Mode.

"…Oh my god it's huge!" Mustard's eyes were widening even if it was in a gas mask then aimed his puny little gun against a GIANT robot and his hands were shaking in fear.

"We got no chance against that thing!" said a marine.

"We survive the first! But so what it's even worse than before!" a Freiza Force member said in fear.

Meanwhile at the Midoriya home

"WHOA! IT'S A GIANT ROBOT!" Eri, Izumi, and Hisashi/Gaban said excitedly with stars in their eyes.

"It seems our son is strong." Inko said as she smile at the three's reaction.

As Boulder agreed at he watches the screen.

Then Eri's eyes glowed red but not because of her quirk it was because of her Haki and saw a future of a horrible sight.

"GRANDPA! TAKE ME THERE NOW!" Eri yelled out loud.

"Huh?" Hisashi/Gaban asked.

Meanwhile at a certain pink haired inventor

"WHOA! THAT IS THE MOST BEAUTIFUL BABY I EVER SEEN! I MUST HAVE HIM!" the pink haired girl yelled out.

"Hatsume Mei get out of my workshop!" Powerloader yelled

Meanwhile at Ochako's location.

"NO WAY! IT'S SO GIGANTIC!" OChako yelled out.

"Oh, crap…" Endeavor said in awe.

"Damn, Deku is at a strong level. I must catch up." Kastuki said.

Back with Izuku/Bullet

"How do you know the name of ROCKS?!" All For One yelled at Izuku/Bullet for why he knows such a legendary name of the ROCKS Pirates.

"Heh, at least 20 to 30 years ago the Roger Pirates fought them and my father was part of the great battle of God Valley," Izuku/Bullet said through his mech's speakers.

"Damn you Bullet. You have the literal power to destroy the World!" Akainu said as he groans.

"We got no chance!" a marine said.

BOOM!

"What the?" everyone thought

BOOM!

"LOOK! IT'S GENERAL DEATHSTROKE!" a marine pointed at a Japanese style fortress.

BOOM!

"I'll take this mechanize beast. I finally was able to repair my fortress!" Deathstroke declared as his fortress transformed into a mech.

"So, it a battle of machines, well come get SOME!" Izuku/Bullet said as his mech threw a punch at Deathsroke's mech and hits it very effectively causing cracks in the mech.

"GIGATON CRASH!" Izuku/Bullet yelled as he made a punch and clad it in Armament Haki.

Deathstroke also used haki on the entire mech to prevent it from breaking.

CRASH!

As the punch hit the haki cladded mech Deathstroke's mech had several cracks in its arm.

Then Izuku/Bullet tried again with a normal punch but it was caught by Deathstroke's mech and fired his main cannon at Izuku's mech.

"FIREING MAIN CANNON!" Deathstroke said

BOOM!

The cannon fired and Izuku/Bullet's mech was damaged but was repairing itself.

Then Izuku/Bullet threw another punch at Deathstroke but he caught it again and was stuck in a hand lock.

"Now I got you where you are… NOW EVERYONE!" Deathstroke said and commanded.

As everyone was attacking Izuku/Bullet's mech with their quirks, Devil fruit, or weapons.

BANG!

BANG!

Mustard was firing his gun at the mech but it was unfazed by it.

"Wait, Bullet has the power to absorb any machinery and improve upon… NO SLADE! GET OUT OF THERE! IT'S A TRAP!" Fujitora thought and commanded.

"Huh?" Deathstroke turned his head at Fujitora.

Then Izuku/Bullet took his chance and rips both arms of Deathstroke's mech and then created a cannon into his right robot arm.

CLANK

CLANK

CLANK

As the cannon were created he aimed it at the mech point blank and fired three times!

BOOM!

BOOM!

BOOM!

As Deathstroke's mech fell it signals the beginning of the end.

"Oh, no Deathstroke was our last chance…" Muscular said with a fearful tone.

"FOUR BLUE CRASH!" Izuku/Bullet yelled as his robot arm grew bigger and clad it in Haki.

CRASH!

As his punch hits the ground which made several big cracks in the ground.

All For One decided to end things.

"EVERYONE AIMED FOR THE NINE ON THAT MACHINE'S CHEST! THAT MUST BE THE PLACE WHERE HE IS PILOTING THE MACHINE!" All For One commanded.

As everyone started attacking the mech's chest and then an attack from Akainu finally made a "scratch".

"HELL HOUNDS!" Akainu yelled as magma dogs attack the chest which melts through the armor revealing Izuku/Bullet in the chest.

Then All For One use a string like quirk to pull out Izuku/Bullet out of his mech.

"NANI?!" Izuku/Bullet yelled out loud.

"NOW FIRE AND THROW YOUR SEA PRISM GUNS AND SPEARS!" Akainu commanded

As everyone started firing at Izuku/Bullet which hits him thus nullifying his Devil Fruit powers. And when his hits the ground bleeding marines threw their sea prism spears which pierced both his arms, legs and one in the chest.

Meanwhile as Ochako's location.

"DEKU!" Ochako cries out as her body was covered in pink lightning.

"No…." Kastuki said as he saw his rival being "defeated".

"…" Endeavor in silence.

As well as Inasa in silence as well.

"He is strong but I think he'll grow stronger if he has a reason to grow." All Might said

Just then…

A portal open and it was Hisashi and ERI?!

"MAMA! WE HELP PAPA!" Eri yelled out and climbed onto Ochako's back.

And before anyone said anything Ochako?! RAN FOR DEKU?! And she and Eri exits the shield?!

"WAIT ROUND FACE COME BACK!" Kastuki yelled out.

Meanwhile at the battlefield.

"YEAH! WE BEAT THE DEMON HEIR!" a marine cheered out.

"Yeah! And we didn't use the Pasafistas!" another marine said.

But then…

"SMASH!" Ochako yelled out as she punches a marine soldier in the face.

Then ran for Izuku/Bullet current location as she started to hit any marine or Freiza Force member.

POW!

SMACK!

SMASH!

"Huh? Who's that?" Fujitora asked as he heard her in the distance.

"That's a girl who is a threat to me… maybe I should lie…She is also Bullet's lover," All For One said with a smirk.

As he said that Akainu order this command.

"MEN KILL THAT GIRL SHE HAS CONNECTION TO THE ROGER PIRATES!" Akainu commanded

As Ochako kept punching or kicking any marine or pirate.

"Heh, heh… That was easy and One For All will be eliminated." All For One said as he aimed an attack at Ochako and Eri a killing blow.

Meanwhile with Izuku/Bullet

"OCHAKO! ERI NO!" Izuku/Bullet thought as time slowed down as he activates the Temporal Distortion device.

As time slowed down Izuku/Bullet cannot move with the sea prism on him negating his Devil fruit powers and bleeding out.

"Is this my punishment for being a pirate? How could I have thought that I was some kind of hero? Thinking I was strong enough to save her.… I didn't get stronger just like back then…" Izuku/Bullet thought with sorrow…

"Are you giving up?...Are you giving up?" a voice asked.

"No… I'm facing fate…" Izuku/Bullet answered.

"Then you are giving up to a government that we once defied." The voice said

"But how can I? I'm up against a legendary villain." Izuku/Bullet said

"Then what our battle against Shiki and his fleet was what? A fluke?" the voice said as he walks towards Izuku/Bullet.

"Huh?" Izuku/Bullet looks up.

"Did you forget the time we spend with each other and that our bonds was stronger than any force thrown at us?" the voice said.

"It can't be you're dead…" Izuku/Bullet's eyes widen in shock as he saw Gol D. Roger?!

"And beside listen…" Roger said as Izuku/Bullet heard their voices.

"DON'T GIVE UP PAPA/DEKU!" Eri and Ochako yelled out as it echoes in Izuku/Bullet's head.

"Stand up Izuku… get up!" as the ghost of Roger disappeared.

As Izuku/Bullet woke up from his dream?

"Hey, come on you haven't called on us yet…" a tiny blue hologram carrying a sniper rifle said

"Hey, Church route power to the healing, speed, and time unit." Izuku/Bullet said as he moves his arm upward to have a free arm to pull the spears out and then stood up.

Clank clank…

"Eh, don't worry looks like your Omega Nanite is repairing your body for you." Church said.

As his wounds are healing.

"Good," Izuku/Bullet said as he ran with extreme speeds grabbed Ochako and Eri and phantom punch All For One in the gut. And then landed on his broken mech.

"Resume…time." Izuku/Bullet said as time began in a normal pace.

BOOM!

"DEKU!/PAPA!" Ochako and Eri cried out as they hugged Izuku/Bullet.

"Hey, now don't cry. Why for I am here," Izuku/Bullet said softly as he puts the two down on his mech.

"You two stay here I'm about to rain in the pain." Izuku/Bullet said as he smirks.

As he jumps down to the battlefield again and then frowns.

"I'm going to make you all pay for targeting Ochako and Eri," Izuku/Bullet said

"Yeah and what you're going to do about it? Huh?" Muscular said.

"I'm going to crush you all and I finally feel "awaken" for the first time… UNION OVERDRIVE TSUNAMI!" Izuku/Bullet yelled as his body glowed purple again but this time he is aiming at everything.

Everyone saw this and began to run!

The purple blocks began like a geyser and then traveled. As the tsunami began to absorb the nearby broken buildings and air ships that tried to fly away or attacking it most were absorbed while a few got a way.

"RUN!" a marine said as both marine and freiza force alike ran like heck.

As the tsunami covered the entire area that was destroy during All Might and All For One's match it stop. Then it recedes back to Izuku/Bullet and the purple light went upwards and forms a colossal beast.

"N-no way he awakened his Devil Fruit!" a Marine said with shock.

"THIS IS THE END! ULTIMATE FAUST!" Izuku/Bullet in his newly acquired Colassus Form covered his arm in haki and made it bigger.

"RUN!" a frantic looking Frezia yelled as everyone ran as fast as they can from the Demon Heir fist.

CRASH!

As the clouds cleared up every villain and/or pirate were down and many marines were also down as well.

Of the remaining 400,000…..10,000 remaining that were not either dead, unconscious, or injured.

"This is a nightmare! This CAN'T BE REAL!" Mustard yelled out since he is a gifted child but he was just a big toad in a small pond.

As the Marines and Pirates got up they heard laughing of a monster who is mocking them.

"KHAHAHAHA!KHAHAHAHA! KHAHAHA!" Izuku/Bullet laughs manically as his shadow looms over the remaining 10,000 men.

"That's it I'm out of here! I don't care if Lord Freiza kills me it is better than this!" a freiza force member said as he ran out of the battle not caring for his wounds or any other people.

Many others took the option of fight or flight or in this case slaughter house or court martial/munity.

Izuku/Bullet saw this and let the many those who want left for 5 minutes only 9,095 remained.

Then Izuku/Bullet's colossus form crumbled as he gotten tired then Hisashi appeared behind Ochako and Eri. And he promise to protect Eri with his mighty axe.

"It's time to end things wouldn't you agree? Chako chan?" Izuku/Bullet said as Ochako jumps down to his side.

"Right! Deku kun!" Ochako said with a smile.

And so the finale of this great battle will begin and a new era will spark new legends that will one day change the future for better or for worst.

TO BE CONTINUE…
