I don't own My Hero Academia or Kamen Rider and they belong to their respected owners.

"I'm not going to let you hurt anyone anymore!" Izuku declared.

Izuku attached his Shining Hopper Progrisekey to the Assault Grip, which Mei created for him. He then pressed the Rise Starter.

HYPER JUMP!

Izuku scans the upgraded Progrisekey.

OVERRISE!

He unfolded the Progrisekey and lifted it up in the air as both Zea and Ark transmit data to the Progrisekey. A bright light appeared on the Progrisekey which resulted in a new Rider Model hovering over Izuku, which appeared more solid. It was in the shape of a grasshopper with the yellow and blue colorings on it.

"Henshin!" Izuku shouted as he jammed it into the Zero-One Driver and shouted.

PROGRISE!

The empty circle that appeared in the Model's stomach shines a blue light on Izuku creating his undersuit.

Warning, warning. This is not a test! HYBRIDRISE!

The Rider Model then designs itself to armor pieces as it slowly descends on Izuku. with the Rider Model unfolding and wrapping around Izuku, as the Shining Gladiators and Shining Hopper Antennae fold into place, completing the transformation.

SHINING ASSAULT HOPPER! No chance of surviving this shot.

Everyone was in shock and awe to see Midoriya's new form. It was similar to Shining Hopper and Vulcan's Assault Wolf Form. They all wonder how strong Shining Assault Hopper is.

Izuku rushed forward with an amazing speed which similar to Shinning Hopper's speed but probably 2.6 slower. Izuku suddenly appeared in front of Tomura and raised his arm and quickly giving a powerful hammer punch on the Grand Commander of the Paranormal Liberation Front, throwing him back and sending him stumbling.

"Deku, behind you!" Katsuki shouted.

Zero-One looks behind him to see a High-End Nomu trying to take a swing at him but Izuku brings out his Authorise Buster.

AUTHORISE BUSTER! AXERISE!

Izuku blocked the High-End Nomu's large claws with his weapon before pushing it back and taking a swing at the monstrous creature. Izuku decided to change his Buster into Gun Mode.

GUNRISE!

He then placed his Authorise Buster by his Driver and scanned it.

ZERO-ONE DUST!

Izuku fires a yellow energy shard that briefly creates an image of a mechanical grasshopper before striking the High-End Nomu pushing it back.

He knew it would regenerate quickly so he had to destroy it fast.

AXERISE!

He brought the Breaking Mammoth Progrisekey and activated it.

PRESS!

He inserted the key into Authorise Buster.

Progrisekey confirmed. Ready for buster.

Izuku creates a pair of silver mechanical mammoth leg constructs that charge at the High-End Nomu who tries to block the mammoth leg constructs but only to fail and be crushed by it.

"Wait, his attack didn't say its announcement…" Touma mumbled. Then his eyes widen as he realizes Zero-One hasn't finished the attack.

As the High-End Nomu slowly got up, Izuku delivered another slash that creates a silver construct of a mammoth tusk that rushes toward the High-End Nomu pushing down on it and destroying it.

BUSTER BOMBER!

Now with Nomu defeated he has to face Tomura and finish this.

Before he could do anything a large foot came crashing down on him. Izuku covered himself with his arms and Authorise Buster. Shining Assualt Hopper was strong but he knew the behemoth known as Gigantomachia was larger and stronger. But Izuku had an ace up his sleeve as his blue Orbital Unit began to glow and activates the Shine System.

Everyone saw the glow and a source of energy blast Gigantomachia back as Zero-One began to float and glow as eight Shine Crystals floated around him. Nobody could believe what was happening. What did Zero-One Shining Assualt Hopper have in its arsenal?

The Shiny Crystals began to glow and fire blue energy wave bullet at Gigantomachia, Tomura charged forward to punch Zero-One but was block the Shiny Crystals. Gigantomachia tried to squish Izuku his fist but the Shine Crystal collided with Zero-One as Gigantomachia's fist smash ontop of Zero-One. As Gigantomachia lifts his fist, the hopper hero wasn't there. As he appeared behind Tomura and kicked him making the villain fall on his face.

Zero-One then jumps onto Gigantomachia's arm as he runs up to the behemoth. Gigantomachia tried to swat Izuku off his arm but Izuku jumped from the giant while the Rider helo his Authorise Buster. Izuku then grabs the Flaming Tiger Progrisekey and activates it.

FIRE!

He inserted the key into Authorise Buster.

Progrisekey confirmed.

He then scans the Authorise Buster to his Driver.

ZERO-ONE AUTHORISE!

Zero-One charges the Authorise Buster, then uses the Shining Arithmetic to dash around Gigantomachia dodging his fist and the other villain's attacks before jumping into the air.

Once in the air, he creates three vertical rows of red fire claws and gives Gigantomachia a slash on the side of his face before finally giving a hard slash with the fiery claws on his face sending him stumbling back.

ZERO-ONE BUSTER BOMBER!

Izuku then zips to Gigantomachia's back confronting the villains who are riding your back as his Shine Crysters keep firing upon Gigantomachia.

"It's over, it's time for you to surrender," Izuku told them.

"Like hell," Dabi says.

"Then, you better get out the way," Izuku says as he quickly disappears from their eyes.

They looked around for him until they heard his weapon's announcement.

Progrisekey confirmed. Ready for buster.

Izuku fires an orange energy construct of the Knuckle Demolition at Gigantomachia's back, the remaining members of the league of villains jumped off of Gigantomachia's back as the construct hit the villain's back, Izuku then fires a second one into the first, combining constructs power pushing Gigantomachia to the ground.

BUSTER DUST!

Zero-One landed in front of the behemoth. He looks at it and notices it was not waking up or getting up. It must have been due to the severity of his injuries he has caused him.

"You damn bastard!" Tomura shouted.

Izuku turns to the still-standing Tomura sees him seething full of anger, Izuku can also see that Tomura's regeneration finally kicks in, and knows that with a chance he will attempt to use his Decay Quirk again to finish everyone off in this area.

"Do you know you know what you just did?!" Tomura growled.

"It's over Tomura, I defeated your strongest and I don't want to use a Rider Kick on you," Izuku tried to persuade the villain.

"Never." Izuku could only release a sad sigh. He heard about Tomura's or should he be calling him, Shimura Tenko, and learned about his traumatic past from All For One.

"Fine, then!" Izuku glared under his helmet. "I'll tell you this Tomura... There's only one person who can stop you... and that's me!" Izuku shouted.

Izuku shot forward with speed faster than any human at Tomura and kneed the pale man into the air. Tomura grunts in pain as he looks down and sees Zero-One jumping towards him. Tomura tried to hit Zero-One with Air Cannons and fired large blasts of pressurized air from the palms of his hands.

Izuku quickly dodged the attack and floated behind Tomura and aimed his foot at him sending Tomura to crash onto the floor as Izuku landed in front of him.

"Let's stop this, Tenko." Izuku is still trying to reason with him.

"Don't ever say that name!" Tomura screamed.

Izuku had to end this, Zero-One then presses the Progrisekey again as he activates his new finisher.

ASSAULT CHARGE! SHINING STORM IMPACT!

He knows his finishers are powerful but even with Tomura modifications it completes he knows he can finish him with a Rider Kick and not kill him.

Izuku leaps up and performs a powerful Rider Kick charged with yellow and blue energy penetrating through the Tomura at high speed. Once, he made contact with Tomura and a huge explosion surrounded them.

As Izuku landed away as Tomura laid on the floor defeated and body decaying.

"It is over?" Katsuki asked.

"Yeah… it's over." Izuku nodded.

Izuku looked at Tomura. 'If you've lived in a better environment… you have been a hero. A hero who stood up for the little people as they should've stood up for you?' Izuku thought in his head. Who knows how Tomura's life could've been.

AN: I thought of this yesterday while reading the latest MHA chapter. And I'll try a Saber one-shot with FSN but I'm thinking I'll wait till Saber gets the King of Arthur Wonder Ride Book. Maybe, we'll see. And sorry for no update I've been down on the slumps lately and I've been getting back into Super Sentai.
