Summoned from another world, the hero is Ultraman Zeta.

The night, which was originally a noisy peace, was silenced by the battle commotion of the Giratina. The weaker creatures all remained quiet, suppressing the sound of life with the fear of death.

The Giratina transformed into its battle stance, towering above the forest. Tonight, the moon was obscured by dark clouds, and the only bright thing on this land was the Giratina's murderous eyes flashing in the darkness.

The Flamefeathered Giant Bird, which had previously sought out the Serpent Dragon to avenge its family members, now struggled to crawl ashore from the river. After its nest was destroyed and its mate killed, the Flamefeathered Giant Bird had been searching for the killer's scent day and night after settling the graves of its family members. Finally, tonight, it found the holder of the killer's scent.

Faced with a formidable foe, the Flamefeathered Giant Bird was enraged and recklessly ignited its flames to burn the beast to ashes. As its natural enemy, the Serpent Giratina flung the giant bird into the river as soon as it exerted its strength. The pained and enraged Serpent Giratina was about to use its battle form to end the foolish bird's life. All of this was the bird's own doing.

The Flamefeathered Giant Bird, knocked into the river, was soaked. Having just climbed to the bank, it was coughing uncontrollably from the water it had just swallowed, and had no time to pay attention to the attack of the Serpent Giratina behind it.

Walking in Tyrannosaurus Rex form, Gairasu strides through the forest toward the river. Each step it takes causes the branches and leaves to tremble like an earthquake. In its battle form, Gairasu unleashes its full power, making a constant noise just by moving.

Having spotted its target after passing through the forest, the Serpent Giratina leaped high into the air with its legs raised, opening its massive jaws to bite at the head of the Flamefeathered Giant Bird.

"I must go help that blue-feathered giant bird. I need your power, Zeta! I can't watch it die in agony!" "I understand, Haruki. Then let's fight together!"

The resonance between humans and Ultraman awakens the ultimate brilliance of the Pure Crystal of Courage. Haruki and Zeta clarify their goal for the battle: to defeat the monster that attacked the giant bird.

He neither cried out for justice nor pursued the truth; Haruki's journey was solely to quell the anger in his heart. Yes, Haruki was furious. He couldn't bear to see those who had lost family members suffer the injustice of fate once more, and he was even more unwilling to see the monsters who fearlessly protected their family members perish tragically.

Zeta fully sensed Haruki's intense emotional fluctuations; these were emotions similar to Haruki's past moments of confusion, but this time Haruki was more decisive. Ultimately, one person's sense of right and wrong cannot change the world's格局 (geju, a concept encompassing overall structure, overall situation, and overall state). The desire to change the external world must begin with changing one's own actions.

Zeta has witnessed Haruki's growth and transformation, and therefore firmly believes that he will make a choice that is true to his conscience. Zeta will fight alongside Haruki, as always.

Before it could shake off the water, the Flamefeathered Giant Bird was the first to sense the approaching danger. Dragging its badly injured body, it hurriedly flapped its wings and fled its original position to avoid the Serpent Giratina's swift attack.

After failing to land its first attack, the Giratina twisted and swung its tail, unleashing the immense power of its massive tail that propelled its enormous body. The tail, thicker than a tree trunk, lashed out so fast that it left afterimages.

The Flamefeathered Giant Bird, struggling to its feet, had no strength left to dodge the Serpent Giratina's tail lashes. Its entire body was sent flying at high speed like a cannonball, landing on the gravel pool by the riverbank, rolling dozens of meters and leaving long scratches before finally crashing into a giant tree, bleeding profusely.

The tireless search, day and night, was rewarded with the discovery of the ferocious beast. The brilliant flames burning all over his body, which could illuminate the entire night sky, were actually just the afterglow of a half-sunset, long since devoid of the warmth of the sun, and unable to provide any shelter or comfort to his beloved.

Its unique and vibrant blue feathers are proof of its outstanding beauty. Just by appearing, it is enough to outshine other birds and show its elegant demeanor. It is precisely because these are the blue feathers that its mate likes the most that it takes extra care of. It wants its mate to know that the creature you love has the most beautiful fiery feathers in the world.

Water droplets soaked the wound, making the pain more acute, and mud mixed into the fur, making the blue color dull and lifeless. Fortunately, my eyes were already blurred by the blood dripping down, otherwise, if I had seen my current ugly state, I probably would have finally given in and cried.

Its feathers were scattered all over its body, and its once dazzling beauty had become a guide for the Giratina to come and claim its life.

Its mouth opens to a melodious song, and its cry can resound through the heavens when it flies. Its beautiful blue feathers are merely a gift from heaven, and its singing voice, honed over many years, is the medal it has earned through hard work. It loves to sing to its mate, as this is its way of expressing love. It is determined to sing the most beautiful voice so that the whole world can bless its family.

Covered in fallen, withered vegetation, the swaying leaves that once seemed beneath the sky now weighed it down, making it impossible to rise. Its blurred vision caught sight of the light reflected in the river, and it cried out, pleading with heaven to let it see the moonlight one last time, even though it knew all too well how unjust the heavens were.

The unpleasant hoarseness couldn't even cross a river, completely drowned out by the footsteps of the snake-like creature, becoming a joke for the ferocious beasts to hunt, mock, and ridicule.

This is what happens when you overestimate your abilities. The Serpent Giratina felt no sympathy for the giant bird that had become as ugly as a monster.

The giant bird, which doesn't sleep at night, flies around wildly as if it's gone mad, making stupid noises in the sky that wake up and scare away all its prey. Finally, it stares at me and stupidly charges at me, as if it's deliberately targeting me.

You like to target others, don't you? Come on, watch me beat you down! You have no real skills, you just bluff. You make such a flashy entrance, but you still end up soaking wet.

Keep yelling? Keep setting fires! If you yell one more time, I'll crush your head with my foot. If you dare set fires again, I'll drown you in the water.

The Serpent Giratina swaggered arrogantly towards the Flamefeathered Giant Bird, waiting for its next move as if toying with it. The Flamefeathered Giant Bird, its life force nearly drained, could no longer cry out. As its life drew to a close, it gazed at the river beside it, staring at the reflection in the water as if in a daze, or perhaps in prayer.

Light? Where is the light?! Isn't the moonlight blocked by clouds? Who else could possibly provide light here?

Following the gaze of the Flamefeathered Giant Bird, the Serpent Giratina finally noticed the light on the river surface. The light behind it did not belong to any category of natural light, nor was it within the Serpent Giratina's understanding of luminous monsters.

What was that? The previously ferocious Giratina suddenly became frightened and confused; an unknown light source had appeared.

The monster's instinctive survival alerted the Serpent Giratina to the danger, and it quickly retreated to the side to see what was happening. With its entire body on edge, the Serpent Giratina saw the source of the light: three giants glowing from head to toe.

Full of fighting spirit, Haruki was determined to respond to the Flamefeathered Giant Bird's battle intent and redeem its wounded body and soul with the most glorious demeanor. It was a night without light, but Haruki would forge ahead with a fiery will, running with all his might to support the hopeful future of all living beings.

As Haruki ran and shouted, purple light shone on the Courage Crystal. The Ultra Medal was summoned and activated, and Ultra Warriors Tiga, Dyna, and Gaia came to this world as illusions, flying over this land in fictional forms, truly illuminating the Flame Feather Giant Bird's renewed yearning for life.

"Transformable at will, a mysterious light. Ultraman Zeta, Gamma Future."

The three warriors unleashed palm beams to further repel the Serpent Dragon, stirring up dust that made the ferocious beast retreat in fear. The figures of the three Ultra Heroes then flew into the air, drawing three streaks of light that combined to form a giant Z-shaped light character. The colorful and holy light seemed to dispel the darkness and fear, and its brilliance was even brighter than the clear sky and the bright moon.

The light symbol descended and changed again, with three Ultraman illusions forming a rectangular portal that allowed the Giant of Light to appear in a brand new form. Red, blue, and silver colors covered his entire body, each tone sharp yet compatible with the others. The golden shoulder armor and the raised hand in his entrance pose originated from the power of the Ultraman heroes, while the bright crystal on his chest represented Zeta's own high fighting spirit.

Ultraman Zeta, Gamma Future Form, has arrived.
