This esoteric strategy left Chen Yu unsure of its effectiveness, but it was worth a try.
At that moment, Daigo unleashed the Power Type's ultimate attack, the Delacium Light Stream, at Evil Tiga.
Originally, Chen Yu's Zepellion Ray was struggling to hold up, but with Daigo's support, the situation lightened.
A loud explosion occurred as the beams collided, creating a fireball that emerged from the impact.
Chen Yu and Daigo dissipated their beams, turning their gaze towards Evil Tiga.
Evil Tiga showed no signs of energy depletion after releasing his beam.
From the clash, Chen Yu quickly assessed the situation. Though Evil Tiga had become gigantic, his beam hadn't strengthened much.
As long as he and Daigo combined their beams, they could neutralize Evil Tiga's attack, if not destroy him outright.
In the original storyline, Evil Tiga also had limits to his energy and stamina; it was unclear if those limits still existed under these circumstances.
"If he still has those limits, then this battle is definitely winnable."
"How can we win? His power is too strong; neither of us can match him!" Daigo expressed his concern to Chen Yu. "Why is it like this? Can light not overcome darkness?"
"Daigo, I know you're anxious, but don't rush." Chen Yu quickly reassured him. "He's still human; he definitely has stamina limits!"
"You're right!" Daigo had an epiphany. "As long as we exhaust his stamina, we can win!"
At that moment, Evil Tiga smirked and launched another round of his dark Zepellion Rays at Chen Yu and Daigo.
Both Chen Yu and Daigo gathered energy once again to counter with their beams.
This time, Evil Tiga's beam attack seemed premeditated.
Chen Yu noted the initial thinness of his beam, which thickened upon contact with theirs.
Unprepared for the increased intensity, Daigo was overpowered and fell to the ground.
Without Daigo's help, Chen Yu struggled alone against the adversary, retreating as the dark purple beam gradually overwhelmed his own.
Chen Yu quickly dissipated his beam and erected an Ultraman Barrier in front of him.
The dark Zepellion Ray hit the barrier, causing Chen Yu's vibrant shield to flicker and vanish.
The beam then struck Chen Yu directly.
Such a powerful beam was too much for Chen Yu without a special form, his Color Timer flashing red.
As the flashing sped up, Chen Yu realized he was in danger of dying under Evil Tiga's beam!
Without hesitation, Chen Yu deactivated his transformation, dispersing into light particles.
The beam hit a building, turning the area into ruins.
Thankfully, the residents had been evacuated, though these were their hard-earned homes...
As the Color Timer flashed, Daigo, refusing to give in, stood up and faced Evil Tiga.
"How can I let you win?" he said, gathering a powerful Zepellion Ray.
The red beam aimed at Evil Tiga, but with a sidestep, he dodged it.
"You think you can attack me with beams? You're dreaming!" Keigo Madoka taunted.
Perhaps used to fighting slower monsters, Daigo nearly forgot the opponent's speed far exceeded his own Power Type.
Evil Tiga then sent a light ball at Daigo, dissipating him into light particles.
The Victory Team members felt despair watching this.
With both Tiga defeated, it seemed humanity's only hope was to fight on their own.
In the cavernous chamber with the open skylight, the defeated Chen Yu stood at the Genetic Light Converter, contemplating.
If the storyline hadn't deviated, Keigo Madoka would have used this device to become an Ultraman.
"A device that turns the human body into light."
With a bold idea, Chen Yu considered using his trump card against Evil Tiga as wasteful, deciding to find another way to break the stalemate.
The yellow-haired dog that led Daigo to the chamber had awakened.
It paced under another monster statue.
Chen Yu guessed the dog might try to stop Evil Tiga.
"Don't go, little dog!" realizing this, Chen Yu urgently advised, "He's not your master anymore, and you can't beat or persuade him!"
The dog, already glowing faintly, turned away upon hearing Chen Yu's words, its light dimming.
Tilting its head at Chen Yu, it seemed to ask who else could stop the rampaging giant if not it.
Chen Yu didn't know if the dog understood, but he smiled and said, "Though I was defeated outwardly, it doesn't mean I can't try again."
As he spoke, a streak of light descended from above, transforming into Daigo.
The disheveled Daigo, clearly defeated, ignored his pain and anxiously said, "What do we do? No one can stop him now!"
Under the influence of dark power, Keigo Madoka seemed to have forgotten his original purpose as a Giant of Light.
While he retained his primary consciousness, his deeper subjective awareness had significantly changed.
Seeing Daigo return, Chen Yu beckoned him over.
"Come here! Quick, Daigo!"
Daigo approached, puzzled but compliant.
Chen Yu pulled Daigo to the Genetic Light Converter and inserted the Light Stick.
"What are you doing?" Daigo asked, watching Chen Yu's actions.
"When you turn into light particles, don't hesitate; charge straight into that evil giant's Color Timer," Chen Yu explained.
In the original story, the device could transform those with genetic light into light particles and forcibly enter a statue.
Perhaps they could force light particles directly into the body of the evil giant.
