"Spiky! Your here?!" Izuku yelled surprised "Thank god you are ok deku!" He yelled noticing his new appearance.

"Lets beat his ass! I will squash the maggot!" Izuku yelled with his wings disappearing turning to dust. "Awe shit I barely got those!"

"Oh it would seem your transformation has a time limit. No matter I will still kill all of you here." All for one said floating into the sky.

"All might! Get back and save your time we will make an opening!" Katsuki yelled blasting into the air engaging all for one.

"Hey don't try to one up me!" Izuku yelled growing in size back to his massive size. "Why must you children constantly throw away your lives!" All for one yelled stopping the jaws of the serpent from chomping down on him. "For such a pointless cause!!!" All for one shouted getting exploded back to the ground releasing the serpent's jaw.

"Just shut the fuck up! You attacked us and we are just fighting back you damn villain!" Katsuki yelled landing on the serpent's head.

"You want all might then you will have to get through us!" Katsuki yelled with all for one gritting his teeth.

"Oh really now? Through the two of you. Two hot blooded teens that have anger issues." All for one shouted with izuku engaging him.

He dive towards him with all for one evading the jaws with the tail smacking him to the ground. Katsuki released a massive explosion while all for one was on the ground burying him deeper.

"Take that you potato motherfucker!!!" Katsuki yelled releasing another blast straining his arms. Izuku smashed his face into the hole where the all for one was repeatedly.

"Deku is fucker dead yet!?" Katsuki yelled with izuku serpent form shaking his head no "Thought so a person like this won't go down from this."

The ground began to shift with massive earth hands forming locking izuku in place. "Such a vile beast of a child. I will have to out you down." All for one said coming out the hole.

"Says the one getting pushed back by pro heros in training!" Katsuki shouted blasting an earth hand destroying it.

"Such a loud mouth I wonder how your parents are if your like this?" All for one questioned "They are the nicest parents I could ever ask for!" Katsuki yelled as izuku broke free roaring at all for one.

"Well if you can't understand deku he says he will kill you!" Katsuki translated flipping him off with a crazy smile.

Izuku lunged at all for one with katsuki shooting explosion at all for one. "Looks like you don't want your quirks brats!" All for one yelled getting pelted with explosions.

He lunged towards bakugo aiming for his head,but getting blocked by izuku's tail piercing it. Izuku's tail instantly heals locking his arm him. So izuku smashed his tail into the ground repeatedly.

Suddenly his tail began to turn to dust and was falling apart. "Good thing I copied that one." All for one said with izuku ripping the part of his tail with that part turning to dust.

"Looks like you are battle smart!" All for one praised with izuku giving him a death glare regenerating the tail.

Izuku reverted back to his human form with steam coming off of him. His eyes had dark bags on them comparable to eraserhead's. "I will put you down you demon!" Izuku tiredly yelled at him.

"Deku! Stay fuckin awake!" Katsuki yelled at him as he kicked away by izuku making him dodge all for one's hand.

"Both of you brats think that you can beat a villain stronger than all might alone?!" All for one yelled with the two said standing up to him "We will be stronger than all might! That includes you!" Katsuki yelled with his palms glowing white.

"PLUS THEY AREN'T ALONE YOU PRICK!"

Suddenly five cannonballs hit all for one in the back. A trail of ice freezes his legs in place restraining his movements.

"Iida! Grab midoriya and bakugo get them out of there!" Momo ordered as iida followed her directions. He sped past all for one picking them up and getting them away.

"ANYBODY WITH RANGE LIGHT THE FUCKER UP!!!" Momo yelled with pony, ashido, aoyama, rin, monama and kaminari firing their quirks at all for one.

Iida got both midoriya and bakugo to safety as he put them down. "Jeez midoriya you are burning up!" He says as they both get up to fight again.

"Stay down! The both of you are hurt and need rest!" He yelled are them.

"Shut up four-eyes!" Izuku yelled as the scales in his arms receded.

Izuku collapsed only after taking a couple feet forward. "Huh my body won't listen to me? That is new." He said with his body releasing more steam. Katsuki went to grab his arm and started to pick him up.

"ENOUGH!" All for one yelled exploding the ice off of him and shrugging off the quirks attacking him.

"You will die tonight like the ones I killed underground!" All for one yelled releasing his dark aura making it hard to move a single inch and breathe.

"SHUT UP!"

They all looked to see where the voice came from to see midoriya being helped up by bakugo.

"WE AIN'T DYING TO A THIEF! THIS IS MY NEW KINGDOM! SO I WILL LEAD MY FOLLOWERS TO YOUR DOOM!" He yelled taking a step forward releasing his aura that countered all for one's giving them all hope.

He walked up momo and she made him two new blades that came out jagged the way he liked it. He took them as his body expanded once more.

Momo noticed a mark forming on his chest that looked like flames covering where his heart is. 'The hell is that? Doesn't matter as long it helps up win!' She thought as she fired her canons again.

'My body feels like it's on fire and it feels great it feels like I can fight for a million years!' Izuku thought with his mark on his chest expanding.

"Beast breathing-no that doesn't feel right." Izuku said to himself as his memories flashed before his eyes remembering his fathers beautiful fire.

"Set your heart ablaze!" He yelled with his blades turning a redish-orange with flames spewing out from his mouth.

'Uncle hisashi's quirk!' Bakugo thought as shiozaki bandaged his arms.

"Oh fire now? Like that will do anything to me." All for one stated with izuku appearing infront of him.

"First Form: Unknowing Fire!" Izuku yelled slicing upwards cutting off all for one's arm burning him.

"Second Form: Rising Scorching Sun!" Izuku shouted slashing at all for one multiple times. "You are just full of surprises!" All for one yelled shooting him back.

"EVERYONE SUPPORT MIDORIYA!!! GIVE THIS BASTARD HELL!" Momo yelled as they all rushed all for one.

"Insolent brats!" All for one said trying to activate his quirks.

"Your not killing any more of my students!" Aizawa yelled with his eyes glowing bright red as the rest of the of the staff showed up.

"Third Form: Blazing Universe!!!" Izuku yelled slicing his blades downwards literally disarming all for one.

All for one kicks away izuku as he get bombarded with bullets, sound waves and all the other ranged with quirks of the students and teachers.

He starts regenerates as he received a massive fist to the face along with a bunch of boulders falling on top of him due to the team work of kodai and uraraka.

Suddenly two things pierced his stomach began to rotate at very fast speeds. "This is for class 1-B you fucker!" Monama and kaibara yelled ripping his guts apart with drills that momo made them.

All for one made a dust cloud as he aimed to kill monama. Monama flinched back as he turned to steel with all for one hitting him with a point blank air blast.

"Fourth Form: Blooming Flame Undulation!!!" Izuku screamed getting infront of monama and pulling out kaibara while shifting the blast into the sky.

"Don't forget about me you piece of shit!" Katsuki yelled sliding to all of one and sending an explosion straight to his chest.

"Icy-hot!!! Do it now!!!" Katsuki yelled with shoto finally using his fire sending a torrent of very hot flames directly at all for one charring him.

Izuku joined in spewing fire from his mouth at all for one.

"FIRE!!!" Momo yelled as the rest of the students fired their ranged attacks at all for one all at once.

"Just die already!" Katsuki yelled shooting another explosion. "Like I said before it looks like you don't want your quirk!" All for one said appearing in front of him placing his hand on his head.

Katsuki yelled in pain as he felt a part of himself was being ripped out. He fell to the ground holding his head in pain. "Well time to die!" All for one yelled shooting an explosion at bakugo point blank.

The dust cleared showing izuku covering katsuki with his body along with his entire back being burned.

"Kacchan?" He said softly laying one of his blades in his hands.

"You will feel the fires of hell tonight!" Izuku said with killer's intent as Kirishima took him away.

"Such a great quirk for me." All for one said shooting sparks from his hands.

Izuku took a stance gripping his sword with both hands looking intently at all for one "Fifth Form: Flame Tiger!!!" He yelled charging at all for one at blinding speeds with his fire forming a tiger as he struck all for one with multiple slashes that burnt his body.

Suddenly something wrapped around his stomach pulling him back. Sero had pulled him back "Midoriya you can kill me later,but get patched up!" He yelled at him.

All for one began to buff up with multiple strength enhancers. He shrugged off the blow from their quirks.

"Guys I think he just got serious!" Kaminari yelled as tooru rapped midoriya in bandages "Come on! Come on! Midoriya when get out there kick ass like you always do!" She praised trying to feed his ego so he could fight at full strength.

"Yeah I will!" He yelled getting up with his blade in his hand.

His mark grew larger as he chanted in his head 'set your heart ablaze!' Over and over.

All for one slapped tetsutetsu away breaking his steel skin on impact. Momo got worried as all of their attacks weren't doing anything.

Izuku landed infront of her with his bandaged body "Spiky ball and chain." That was all he said as she listened to his order.

He took a stance the area around him began to burn as his chest glowed orange with fire. His blade turned a light red as the fire around him grew in size and out of his control.

"Ninth Form: Rengoku!!!" He yelled dashing towards all for one with his fire enveloping him forming a dragon as he got closer the bandages burned off adding fuel to the flames burning brighter as if it was daylight.

He collided with all for one making massive dust cloud along with a fire tornado.

"HAHAHAHA!!!" All for one laughed as the dust settled with a very burnt and cut up all for one with his fist inside izuku's chest.

"I thought you almost killed me,but looks like that little power up of yours ran out at the last second!" He yelled with no steam rising from izuku anymore.

"That quirk of your will do great for me!" He said reaching for izuku's head that slightly shifted to the slide.

"LIKE HELL YOU'RE TAKING HIS!!!" Katsuki yelled with tears releasing a massive wind torrent slicing all for one's arm off. He threw a bottle that momo gave him at all for one lighting him on fire.

He grabbed izuku chucking him at the rest of the students then slammed the blade into all for one's foot as sero pulled him out.

"HE ISN'T HEALING!!!" Tooru yelled as blood continued to leak out of izuku. Momo thought about what to do she check his pulse that somehow was still there then got an idea "MIDORIYA IF THIS FUCKS YOU UP I WILL PAY YOU BACK!!!" She yelled stabbing him with adrenaline that she made.

His eyes shot open as steam rose from the wound healing rapidly. "Chain!" He yelled as momo nodded happily that he didn't die.

A chain appeared from her stomach. He grabbed it and pulled out a long chain with a spiked ball. He ran towards all for one that douse the flames on him.

"THIS IS THE OPENING!" Izuku yelled wrapping all for one in the chain with the spiked ball locking him in.

Izuku held the chain tightly no matter how much all for one struggled to get out. Katsuki, sato,shoji and shishida also latched onto the chain holding their ground as all for one tried to escape.

"IT IS QUITE SAD THAT THE YOUNGER GENERATION IS SHOWING ME UP, BUT THANK YOU FOR IT!!! YOU ALL HAVE GONE PLUS ULTRA NOW LET ME LET OUT MY FINAL BLOW TOO AS THE TO BEING NUMBER ONE HERO!!!!" All might yelled in his one armed buffed form.

"UNITED STATES SMAAAAASSHHH!!!!!" He yelled out as izuku transformed into his giant snake form to protect the rest of the students and staff with a large amount of wind pressure hit them.

The dust settle and all for one laid still on the ground finally down after all they did. All might raised his fist into the air as the news crew capture the entire fight cheered along with everyone watching.
