The Zepellion light beam, as the Composite Type's ultimate move, had even greater power than the airborne and powerful type's ultimate attacks!
Of course, the power of the Powerful Zepellion light beam was even greater, and if the energy had been sufficient, Chen Yu and Daigo would have undoubtedly chosen to unleash another Powerful Zepellion light beam.
As the two beams of purple and white light converged and struck Katanja, everyone watching the battle held their breath.
Everyone knew that once the gem-like object on the Ultramen's chests started flashing red, it meant the Ultramen's energy was running dangerously low.
If the second ultimate light beam couldn't defeat Katanja, the two Ultramen would undoubtedly be locked in a fierce battle, and humanity would lose its final hope.
Perhaps feeling pain under the assault of the purple and white light, Katanja let out a roar, and its tentacles, like devilish claws, began thrashing wildly.
When Chen Yu and Daigo finished releasing their light beams, another explosion erupted from Katanja's body.
This time, both of them could clearly see that after enduring four beams of light from two attacks, Katanja's body had turned black and emitted continuous white smoke.
"The Ultramen's attack worked!"
New City, watching beside a laptop in the shelter, exclaimed excitedly.
However, after a long wait, the expected explosion of Katanja did not occur.
Instead, Katanja lifted its front body, revealing the indescribable mass of tentacles underneath. Then, four huge claws emerged from that area, each striking towards Chen Yu and Daigo.
Both Chen Yu and Daigo were at their limit after releasing the second ultimate light beam. Even though Masaki Seigo controlled the light energy transmission device to continuously shine light on Daigo or Chen Yu's timer, the energy replenishment was minimal.
It would take some time to fully replenish their energy.
Faced with the attacking claws, Chen Yu and Daigo chose to retreat.
After a difficult joint effort to knock down the four claws, Daigo looked at Chen Yu with determination and said, "You go replenish your energy first. I'll hold it off!"
This was the best way to fight now: one person replenished energy while the other held off Katanja. However, with the remaining energy of both of them, whoever stayed behind would be in danger.
Chen Yu's initial reaction was to let Daigo replenish his energy first, as the people on Earth were more familiar with Deiga than Tregear. If Deiga were defeated in the end, the probability of the appearance of humanity's hope would be greater.
However, after Daigo's statement, he rushed towards Katanja, launching a melee attack against it.
Without the energy to release light beams, they could only rely on basic close combat.
Seeing this, Chen Yu had no choice but to approach the light energy transmission device to accept the light radiation.
Watching Daigo in battle, feeling his energy gradually recovering bit by bit, Chen Yu hoped that the energy recovery speed could be faster.
All eyes were focused on Daigo fighting against Katanja.
Everyone understood that Daigo was delaying time to allow the other Ultraman to recover energy. However, as time passed, their worst fears came true.
With insufficient energy, Ultraman Daigo was entangled by Katanja's tentacles and unable to break free.
With only one hand left, Daigo noticed the circular arm insert on the ground beside him.
Without hesitation, he pulled out the circular arm and used his last strength to desperately sever three tentacles and cut off one approaching giant claw.
Breathing heavily, Daigo's gaze shifted to Chen Yu's chest.
The red light on Chen Yu's timer was still flashing rapidly, indicating that his energy had not recovered at all and was far from being enough to release another ultimate attack.
Meanwhile, the red light on his own timer was flashing at its limit.
With a strong will, Daigo stood up, grasping the circular arm with both hands, leaping into the air, and then descending from above, thrusting the sword towards Katanja's head!
With a sharp clang, sparks flew everywhere, indicating that Daigo's blow had inflicted considerable damage on Katanja.
However, along with the sparks, black mist erupted from Katanja's body, continuously exploding around Daigo.
Under the assault of the black mist, Daigo staggered back, emitting sounds of pain.
"Quick, give the light to Deiga!"
Chen Yu, seeing Daigo's plight, didn't care that his energy hadn't fully recovered enough to release another ultimate attack. He aimed the light energy transmission device at Daigo's timer and projected light onto it.
However, under the attack of the black mist, the light was just a drop in the bucket.
Tentacles emerged from the black mist, unexpectedly entangling Daigo's limbs.
With a roar, Katanja turned towards Chen Yu.
Perhaps this monster's intention was to turn both Ultramen into stone statues, plunging humanity into even greater despair.
