Ultraman, Tiga, and Chen Yu worked together to push the massive fireball away from Earth's atmosphere. Battling a cosmic calamity beast like Dizastrous could potentially cause widespread damage on Earth, risking countless innocent lives. Thus, taking the fight into space was the best course of action.
Dizastrous was immense, dwarfing all three Ultramen combined. This was only its fireball form; its true form was expected to be comparable to Gigakimera or Belial, but likely smaller since the trio managed to move it.
As they returned to space, Dizastrous let out a roar, its fiery guise dissipating to reveal its true form, as Chen Yu had predicted. Roughly the size of Gigakimera but slightly smaller, Dizastrous appeared ferocious with crimson eyes, a mouth full of sharp teeth, a black body, and strong limbs. It even had bat-like wings fluttering slightly.
"This is the true form of Dizastrous!" Chen Yu finally witnessed the creature only mentioned in the script. Dizastrous's roar was followed by a yellow energy blast towards Tiga, who quickly raised an Ultraman Barrier to block it.
Switching to Sky Type for its speed and agility, Tiga moved with ease in space. Chen Yu and Ultraman didn't have the luxury of form changing, so they attacked directly. Ultraman threw a Specium Slash at Dizastrous's head, while Chen Yu, as Leo, executed a fiery kick aimed at the creature's eye, knowing it to be a weak spot.
The Specium Slash was deflected by Dizastrous's scales, but Chen Yu's fiery kick hit its target, causing Dizastrous to howl in pain and blindly swing at Chen Yu, who countered with a series of kicks - yes, kicks, because in the universe, boxing includes leg techniques too.
Dizastrous, however, remained largely unharmed by the onslaught. Tiga, from behind, launched a Freeze Ray at Dizastrous, which simply ate the icy blast, changing its skin color to blue, and retaliated with a frigid breath at Ultraman, who shielded against it. The creature didn't stop there, following up with a flame attack that shattered Ultraman's barrier.
With the barrier gone, Dizastrous unleashed an electric arc. Ultraman, deciding not to dodge, took the hit directly and countered with a Specium Ray aimed at Dizastrous's eye.
Chen Yu, wondering if another weak point similar to Gargorgon's existed, ventured below Dizastrous, only to find no apparent vulnerabilities. As Dizastrous launched a purple energy attack at Tiga, who evaded, revealing its power to tear through dimensions, Chen Yu was astonished by the beast's might.
Unable to discern Dizastrous's weaknesses, Chen Yu considered an internal attack. Shrinking down, he entered Dizastrous's mouth during a roar and made his way to its stomach, unleashing a barrage of attacks on the internal organs. Dizastrous roared in pain, unable to counter the internal assault.
Finally, Chen Yu, having wreaked havoc within Dizastrous, decided it was time to finish the beast. Enlarging within Dizastrous, he burst out, covering himself in filth but undeterred. He spun in space, launching a powerful ray from his hands at the weakened Dizastrous, while Ultraman fired another Specium Ray, and Tiga, now in his Multi Type form, released a Zeperion Ray.
The combined attack was too much for Dizastrous. It exploded in a blaze of glory, ending the threat it posed to Earth. The unconventional strategy of attacking from within was a surprise to all, showcasing the versatility and unpredictability of Ultraman's battle tactics.
