Kamen Rider Deku | My Hero Academia X Kamen Rider

Before long, a white apparatus materialized in his hand! Without hesitation, he brought it to his waist! A dark gray metallic belt quickly circled his waist and tightened!

[IMAGI FUSION DRIVER!]

The white apparatus announced its presence, alerting not just Katsuki, but finally also the Cat Imajin...!

"NYA NYA?!"

The creature finally noticed the new presence of both Izuku and Katsuki. It turned toward them, baring its sharp claws, and began to hiss angrily!

HISS!

"Guess you're not a fan of visitors, huh?" Izuku joked towards it, smiling. He was unfazed—not one bit—by its threatening act.

He then raised both of his hands to the air, and another digitized aura enveloped both of them at the same time. Two USB-like objects appeared simultaneously in his hands!

"W-what are those...?" Katsuki whispered curiously from way behind him.

This was the first time she had ever seen these odd apparatuses of his...

'No... I have seen them before.'

She corrected herself, finally remembering vaguely these devices...

They were the things that had been attached to him back then as the 'green vigilante' who had saved her...

And here she was... about to witness the very transformation of his that would turn him into her savior in green...!

Izuku crossed both of his arms and then pushed the trigger on each of the USB devices...!

[GRASSHOPPER!]

[METAL!]

Both devices announced their identity. He then uncrossed his arms and brought each of them to each side of his white apparatus—inserting them into it!

[GRASSHOPPER!]

[METAL!]

[PERFECT FUSION!]

As soon as the apparatus finished its announcements, a burst of wind suddenly erupted out from him—seemingly as if his own aura exploded!

But that was just the beginning.

Something came out from his white apparatus—a green, holographic-like giant grasshopper appeared, jumping energetically around him!

"SHRIEK!"

It shrieked cheerfully, announcing its presence, and jumped around even more, creating more gusts of wind. It even cleared the dust and debris around Izuku!

And that was not the only thing that came out from the strange apparatus.

Suddenly, columns of gray metallic beams surrounded Izuku and planted themselves into the ground, circling him! These beams of metal anchored themselves into the earth, forming a sturdy perimeter as the holographic pet bug continued to jump around him.

And for Katsuki?

"Amazing..." she breathed in awe, her voice barely above a whisper. She was struck with wonder, unable to tear her eyes away from the unfolding spectacle.

Unfortunately, though, his next few actions would confuse her greatly instead.

Izuku raised his right hand, extending it diagonally across his torso and high above his head to the left. Meanwhile, his left hand formed a fist, coiling back and positioning itself beside his newly formed metallic belt.

His right hand moved counter-clockwise, tracing a slow, deliberate circle around his form. As his right hand was about to complete its arc, his left fist unfurled, and he began to mirror the movement of his right—both arms now circling his body in sync.

It was as though he was performing some kind of ritual, casting an unseen mantra with each sweeping motion of his arms...

Then, with a sharp fluidity, he pulled both arms back to his torso, crossing them over his chest to form an "X," both hands clenched into tight fists!

With a sudden shift, he pulled both elbows back! He pulled both thumbs out, and both hands hovered above the triggers of his white apparatus...

"… Henshin!"

In an instant, he drove both thumbs downward, pressing the triggers of the apparatus!

The world around him seemed to freeze for a moment...!

But a surge of glowing lights suddenly enveloped Izuku, their intensity bright and blinding to the eyes! His figure disappeared for an instant, swallowed by the radiant glow!

Then, as the lights began to fade, a dark-gray, almost black form-fitting suit materialized, covering him from head to toe.

The metallic beams that had once circled him now began to rise from the ground, stretching upward with a mechanical hum...!

They began to twist and morph, forming leg armor first, then arm guards, followed by torso and shoulder armor, each piece clicking into place with precise, mechanical movements!

Finally, the last beam took shape, molding into a helmet with a bug-eyed visor...! It descended onto his head and locked into place!

The jumping holographic grasshopper, still buzzing around Izuku, suddenly stopped. But then, it turned toward Izuku and shot toward him, its form breaking apart as it turned into a surge of green energy!

The energy spread across his armor, infusing it with vibrant green, bringing the previously gray, colorless suit to life!

The once dull visor of his helmet then glowed a fierce red...!

[THE ARMORED JUMPING RIDER! METAL HOPPER!]

His glowing white apparatus announced once more, bringing his gallant figure to attention...!

Katsuki's eyes widened in awe as she gazed at Izuku's transformed figure.

"It's really you, Izuku..."

The "green vigilante" figure—the same one that had saved her life once before—stood before her, tall and powerful...!

The suit, dark-gray and sleek, now shimmered with vibrant green energy, and she could feel it—that aura of strength radiating from him, and for a moment, it felt as if the world itself bent to his presence...!

The gust of wind from his transformation still swirled around them...

Izuku raised his right hand, and from it... a long, white scarf materialized! It fluttered wildly in the wind, like a flag in battle, caught in the fierce rush of air around him.

Then, with calm precision, he took the scarf in both hands, wrapping it neatly around his neck as it continued to flutter in the wind.

Behind his mask... a smirk formed on his lips.

"Let's do this...!"

Without hesitation, he charged toward the Cat Imajin—leaping high into the air! His body poised, ready to deliver a powerful flying side kick!

"Rider Kick!!!"
