This is the Earth of another world, where there are no Kamen Riders, but they are also being invaded by evil organizations.

The evil experimental empire of Metz has launched an all-out attack on the planet, and they have turned the target of the experimental transformation to Earth, preparing to transform life on Earth into an invasion weapon of the Metz Empire.

But fortunately, although there are no knights in this world, there are also righteous warriors against evil - 20 years ago, five children kidnapped by the Mace Empire from the earth, accidentally fell to the Twinkle Star, where they underwent the hard training of the Twinkle Star people, and today, 20 years later, they returned to the Earth to resist the invasion of the Mace Empire.

They're called Supernova Flashers!

Using the Flashstar's high technology and the strength gained from hard training, they have won victory after victory.

But now, the flash man is in a huge crisis.

"Dayi, Shanna, Pengan, Lue! Wake up, wake up! ”

The captain of the Flash Man, Red Glitter Gene, collapsed to the ground, he was now exhausted, and four terrifying, beast-like figures surrounded him.

It was his comrades-in-arms, the other four Flashmen.

However, during the recent battle, the four Flashes were controlled by an orc warrior named Ze Ragil, and although Red Flash escaped, he had to endure the attacks of his former teammates.

Now, it's time to burn out.

Witnessing the end of the red flash, the leader of this operation, the alien general Sa Kuller, known as the Shadow Hunter, watched with a sneer.

Jean saw him and said angrily:

"Kuler, I won't let you go!"

"Stupid, your partners are all controlled by me, if you want to destroy me, I will kill them all."

Sa Kuler sneered without hesitation.

As he said, the four flashers were his subordinates and his hostages at the moment.

If Jean wants to save the four people, he must not attack him, but if he doesn't, he will be beaten to death by the four flashing crowds sooner or later.

What to do?

Jean is forced to make a brutal choice, whether to give up his own life or risk the lives of his teammates?

Jean did not hesitate to this, he raised his scarred head and said to Sa Kuller:

"My life, if you want, take it, and exchange their sanity for my life!"

"Well······· Attack! ”

Sa Kuller ignored him and coldly gave the order.

Seeing that the four flashers were about to deliver the fatal blow to Jean, suddenly, a silver light fell from the sky and suddenly passed in front of Jean and the four flashers.

"What is this?"

Sa Kuller was surprised, caught off guard by the sudden turn of events.

Not only him, but Jean as well, looked at the source of the light, and at that moment, the roar of the engine rang in their ears.

Buzz——!

The cyan light fell from the sky, galloping along the silver-white path of light, instantly swept over Jean's body, and the terrifying wind pressure carried knocked all the five flashers to the ground, and for a while, the attack of the four flashers was forced to stop.

This scene stunned everyone, and even another Mace unit hiding in the shadows stopped attacking.

Everyone's attention was attracted by the cyan light.

Under their gaze, the brilliance converged, and the real body emerged - a silver locust-shaped locomotive, revealing a sense of technology different from that of Shining Star and Mace, and on the locomotive, the silver-and-black warrior let go of the handlebar, stopped the car and slowly got off.

Click-click——!

The moment he landed, the huge leg trigger on his heel rose and fell with a crisp sound.

The eyes like jade scanned the audience, and for a while, everything was quiet, and everyone didn't dare to act rashly because of this sudden person.

Finally, Sa Kuller couldn't help it at first, and asked out loud:

"Who are you?"

"Hmm······ A passing Kamen Rider Kagegetsu! ”

The silver warrior seemed to hesitate for a moment, and then replied.

And this unfamiliar name made everyone look at each other, and Sa Kule frowned, and said:

"Kamen Rider Shadow Moon? Forget it, I'm not interested in you, get out of here. ”

After thinking about it, Sa Kuller still didn't plan to make any extraneous problems, and the top priority now was to solve Jean, and leave the rest alone, so the alien general rarely expressed some kindness.

However, his well-intentioned counterpart did not appreciate it.

Shadow Moon scanned the audience, and then slowly looked at the five Jeans.

"Not good! Alien Hunter, Attack! ”

Seeing this, Sa Kuler sensed that something was wrong, and he immediately ordered his four alien hunters to attack, but it was too late—Shadow Moon's fists slammed into his waist, and the cyan emperor stone shone brightly at this moment.

"Shadow Flash——!

The cyan brilliance suddenly erupted, forcing Sa Kuler and his alien hunters to subconsciously cover their eyes.

Surprisingly, Jean, who was in the center of the flash, was not in any discomfort, and he looked around in surprise - the four controlled teammates covered their faces in pain, and under the light of the cyan flash, the hideous masks broke away from their faces.

"That's the mask of an orc warrior? Are you helping us? ”

Jean watched in amazement.

Breaking away from the glitterer's mask and struggling in the air in pain, before they could react, several cyan rays of light shot out in an instant, knocking all the masks to the ground with precision.

This also allowed the four flashers to fully recover.

"It's ·····"

"What's wrong with me?"

"It's like a dream..."

"Jean!"

The flash of getting out of control is still a little confused, looking at all this in confusion.

Fortunately, Jean's reaction was very fast, and he hurriedly stepped forward and briefly explained the situation to everyone:

"You have just been controlled, and he helped you get rid of it."

"Huh?"

The four of them looked at Shadow Moon in surprise.

At this moment, Shadow Moon looked at Sa Kuller, who had just recovered, and said:

"You're the Lightning Samurai (イナズマ服), right?,You're going to go!"

"Forehead······ It's Flashman! ”

Huang Flash Shana subconsciously retorted.

But now was not the time to think about this, and under Jean's leadership, the five of them gathered to transform again, and the transformation device on their wrists shone brightly, it was the light from the shining star.

"Glitter Prism!" x5

In the shouts of the five, the five rays of red, yellow, blue, green, and pink wrapped the five people.

The light dissipated, and what appeared in front of everyone was the tenth super team!

"Supernova Flashman!"

Boom ——!

As the five of them announced their names, five explosions exploded behind them.

And the shadow moon on the side did not stop, he slowly raised his right hand, and the cyan light condensed on his fist:

"Prince of Shadows, Kamen Rider Shadow Moon!"

At this moment, Super Sentai and Kamen Rider join forces to fight against each other!
