On an unnamed planet, X and Geed confronted against a pair of black Ultramen who took upon their likenesses in appearance. Through the stolen light powers, the dark counterparts seemingly defeated their rivaling templates. Meanwhile on Earth, Grigio was practicing her Grigio Shot in order to protect Ayaka City in her brothers' absence, until she found herself in the middle of the fight between Zero and Dark-Killer. The black Ultra banished the two into a portal. On the Land of Light, the Minato brothers found themselves teleported into the Space Garrison's headquarters from their respective foreign countries and were greeted by Taro and the rest of the five Ultra Brothers.
Despite the harsh condition in Dark-Killer Zone, Zero and Grigio properly introduce themselves to each others. Hearing the news of their sister's kidnapping, Rosso and Blu flew away before Taro could finish his sentence. Meanwhile, X and Geed Darkness ambushed Ultraman Orb on Planet O-50, the latter proceeds to use both of his lightning related forms.
While flying in space, Rosso and Blu were attacked by a mysterious figure and crash-landed on a planet. On Liquitor, the Planet of Water (水の惑星リクエター Mizu no Wakusei Rikuetā), a lone Ragon becomes a target of a Peguila before Ultraman Ribut interferes and kill the monster with Galaxium Blaster. After having a chat with the grateful Ragon, he received an Ultra Sign from Taro. Having been defeated, Orb reverted from Hurricane Slash to Orb Origin and the evil Ultras started to drain his light energy. Victory interrupts in the middle of the process and proceed to protect the defenseless Orb.
Etelgar introduces himself to Rosso and Blu on Penol, the Planet of Rocks as both forces engage on a combat. Ribut appears to bail the brothers under Taro's orders out while reprimanding them for their recklessness. On O-50, Victory smokescreens the evil knockoff Ultramen with Victorium Burn to cover his and Orb's escape. Lugiel attempts to dispose the weakened X and Geed in Sundowin, the Planet of Twilight before his other self, Ginga, appears.
With their remaining energy, X and Geed fire their finishers on Dark Lugiel, allowing Ginga and the two to escape. Noticing that Grigio is slowly weakening, Zero donated some of his energy to her. On the Land of Light, all New Generation Heroes assembles as they hear Taro's story of Ultra Dark-Killer, preceded by X and Geed's encounter with him that lead to the creation of their evil clones. Dark-Killer's revival now involves resurrecting Dark Lugiel and Etelgar along with him as the Ultras prepare to stop him.
In the Dark Palace of Planet Tenebris, Dark-Killer creates Orb Darkness with Orb's stolen light and contemplates to use the Darkness copies as his tool in eradicating Ultra Warriors. While Lugiel and Etelgar picked Ginga and Victory as their respective opponents, a red-eyed giant shrouded in blue aura reminds them that they need to complete all the copies of New Generation Heroes. Although Dark-Killer intended to do so, the mystery giant is only interested in both light and darkness as an equal force. Dark-Killer sends his transmission to the Land of Light, where he implores the Ultras to his planet by threatening both Zero and Grigio. Despite knowing full well of the planet's hazardous environment and Dark-Killer's true plan, the New Generation Heroes race towards it while the Ultra Brothers watch from afar, so as the blue giant from his magical space
X, Orb and Geed left behind to fight their copies whereas Ginga and Victory faced Lugiel and Etelgar in the Dark Palace. In the Dark-Killer Zone, the namesake creator ambushed Rosso and Blu as their energies quickly ran out.
Each of the New Generation Heroes fought their respective opponents to the point of using alternate forms of their own. After holding out against Grigio's brothers on his own, Dark-Killer took advantage of Dark-Killer Zone's absorbed light and use it to manifest Zero Darkness.
Zero Darkness went to fight against Zero and Grigio as Dark-Killer turn his attention to the brothers and absorb their light energy. Ribut invaded the magical sphere thanks to an intel from the Galaxy Rescue Force and quickly deduced the "blue giant" as the fallen Ultra, Tregear. Ribut attempts to fight, but Tregear simply toys with his opponent. While the Ultra Brothers watched from afar, the New Generation Heroes continue to struggle against their counterparts. Due to having resupplying Grigio with his energy the whole time, Zero is nearing exhaustion. Outside the Dark-Killer Zone, the Ultras accessed their forms and fusion based on their experiences with Zero.
With her remaining energy, Grigio managed to hold off Zero Darkness and replenish her brothers' Color Timers, allowing them to form Ruebe. Whereas Ginga Victory, X, Orb and Geed managed to defeat their counterparts, Ruebe turned his attention to Dark-Killer after killing Zero Darkness and seemingly delivered the finishing blow to the villain.
Ruebe splits back into his components as the New Generation Heroes regroup with Zero and Grigio. Seeing the defeat of the League of Darkness, Tregear unleashes his dark energy to resurrect both Dark-Killer and Zero Darkness, the former turned into a mindless rampant that is several times bigger than his original height. As Tregear leaves his magical space, a pair of Red Kings took his place in against Ribut. Geed and his predecessors recreate the New Generation Capsules for Zero to access Zero Beyond and face his doppelganger. While the five said Ultras access their strongest forms (Ginga merges with Taro to become Ginga Strium), the O-50 siblings merged into Gruebe for the final fight against Dark-Killer.
Ribut engages in the fight against both Red Kings and finally killing them with Remote Cutter. As the Red Kings exploded behind him, he leaves the rest to the New Generation Heroes. In their empowered forms, the New Generation Heroes unleash their attacks on the enlarged Dark-Killer as Zero had finished his doppelganger off with Twin Giga Break. Dark-Killer proceed to recreate his Darkness Ultras to consume them and grow even larger. Taro pleaded the New Generation Heroes to donate their powers for Ginga Strium to perform New Generation Dynamite.
Dark-Killer's destruction cemented his permanent defeat from ever returning back. In a dimensional subspace, Zero warned them that their battle were far from over yet, as Grigio's kidnapping was done so as to prevent Gruebe from being formed. Before they could puzzle the clues together, Tregear appears and admits himself being the mastermind of said incident, gloating that he would soon target the Land of Light and Taro. The rest of the New Generation Heroes decided to chase Tregear towards the Land of Light. Zero sent Grigio back to Earth in order to protect Ayaka City in her brothers' absence, while preventing their participation from chasing Tregear altogether.

Part 1 of 3. A long time ago, in the era of the Ultimate Wars that occurred tens of thousands of years ago… While a ferocious battle was unfolding between Alien Empera's monster army and the Land of Light, Ultraman Ken (later the Father of Ultra) and Ultraman Belial gave battle without yielding. While they were heroes who fought together, Belial was unable to accept the distance growing between them as Ken was appointed captain of the Inter Galactic Defense Force and won the heart of Ultrawoman Marie (later the Mother of Ultra). He began to seek even more power, behaving more and more recklessly... At that moment, the golden giant Absolute Tartarus appeared and whispered, "Don't you want to change your fate?" Years passed, and in the Land of Light there was a scientist named Ultraman Tregear. Filled with regret that he was unable to join the Inter Galactic Defense Force and complicated feelings for his close friend Ultraman Taro, the “Emissary of Light,” Tregear devoted himself to do
