Even though barely any time had passed since Zero evolved into MetalGreymon (Virus) and MasterTyrannomon, and logically he shouldn't even be fully accustomed to these two Ultimate forms yet—
In this state, Zero nonetheless triggered yet another Parallel Digivolution immediately.
Or rather, the previous two digivolutions were merely paving the way for this exact moment.
By engraving both the mechanized remodeling data of MetalGreymon (Virus) and the draconic data from MasterTyrannomon into his DigiCore, Zero finally awakened another power hidden deep within himself.
No—perhaps this was the power Zero truly knew best. Those previous two evolutions had only been stepping stones, allowing him to open this particular evolutionary pathway in one breath.
If he had to pick a form to serve as his true frontline fighter right now, naturally it would be the one he was most familiar with—wrapped in blazing brilliance, MasterTyrannomon rapidly reconstructed itself into GeoGreymon's shape once again. But this time was clearly different.
Crimson mechanical armor surfaced, covering half his body. Bones and muscles within were replaced with sturdier alloy bones and high-strength synthetic muscles, granting him unmatched endurance for prolonged combat.
His familiar, shining silver trident revolver reappeared. Just gripping this beloved piece of equipment made Zero feel a wave of emotion.
…Ah, my dear wife, welcome back!
What's wrong with a man treating his gun like his wife?!
Moreover, the armor extended backward from his torso over his shoulders, fanning outward into wing-like mechanical extensions. Even his skull and facial structure were encased in mechanical plating.
More than half of his flesh and blood had now been replaced by machinery, perfectly transforming him into a superweapon created purely for slaughter!
Trident Revolver, Booster Wings, Alloy Skeleton, Giga Destroyer mounted on his chest…
…No longer the fragile glass cannon he once was—now he stood as a genuine killing machine, blending attack and defense, land and sky!
The direct evolution from GeoGreymon—
"—RizeGreymon!!!"
As expected, this evolutionary path felt the most comfortable—after all, it was the one he'd used the longest. With a furious roar echoing through the heavens, Zero charged forward without a second thought, raising his trident revolver and slamming it down in a devastating "Solid Strike"—combining the kinetic energy from his high-speed dive with the Chrome Digizoid-forged trident revolver, even without firing, this impact alone was too powerful for ordinary Ultimate-level Digimon to withstand. Most average Champions would lose half their lives just by brushing against it.
Ultimate-level Digimon varied greatly, to the point where hardcore power-scaling maniacs might divide them into categories like "half-step," "threshold," "gatekeeper," or "peak."
Aside from weirdos whose actual rank was clearly mislabeled—like Kimeramon, supposedly an Ultimate but practically Mega-tier—RizeGreymon's strength undoubtedly stood at the absolute peak of Ultimates!
In comparison, the gigantic devil, though also Ultimate-level, began to show clear signs of inferiority against RizeGreymon.
Back on File Island, it had easily suppressed the Champion-level Zero and Hajime, even holding its own against the collective beating from half the island's Digimon until Rina finally triggered the power of four Crests to defeat it.
But now, with just a single Solid Strike from Zero alone, when the gleaming silver gun barrel slammed mercilessly into its face—the once-arrogant devil tasted agony like never before.
See…when a boss is supposed to die, it really should just obediently die—at least that way it preserves a bit of dignity. If you stubbornly refuse to stay dead and keep popping back up, getting thoroughly stomped is inevitable…
This single strike sent the enormous devil hurtling downward, crashing violently into the mountains below.
Thankfully, Zero had already calculated the angle of impact perfectly. An Ultimate-level Digimon's DigiCore computational power far surpassed even supercomputers, let alone a combat-specialized form designed by the Metal Empire…
That seemingly brutal strike was, in fact, meticulously calculated in the moment it landed—achieving maximum destruction with minimum effort!
The gigantic devil's body crashed precisely into undeveloped mountains, safely away from the Shinomiya family's buildings.
Even so, the shockwave from its massive form hitting the ground triggered a powerful tremor throughout the mountain range.
The onlookers watching the battle had long since been stunned into speechlessness. This terrifying level of combat completely shattered common sense, rivaling even modern weaponry's greatest destructive devices.
After all, top-tier Ultimates already had nuclear-level destructive capability; as for Megas—planet-surface cleansing and ecological destruction were common sights. Higher-tier entities casually tossed planets around as weapons, and some god-like maniacs even aimed at rebooting worlds or jumping to multiversal scale…
The power displayed by these two Ultimates right now was merely a tiny fraction of the greater universe—but even so, it was more than enough to leave ordinary humans dumbfounded.
The massive devil, still dizzy from being smashed down by Zero's gun-barrel, couldn't understand why—even though it was clearly stronger than back on File Island—Zero could dominate it so effortlessly.
The difference in strength shouldn't possibly be this huge…
Zero, of course, couldn't care less about the devil's confusion. This devil had haunted them relentlessly, refusing to stay dead…
…First, forcibly controlling Hajime. And now, injuring Rina like this.
To Zero, these two were undoubtedly his most precious companions—and now the devil had managed to hurt them both.
This drove Zero's rage straight to its peak. Coupled with a mysterious buff from some unknown entity just casually passing by, the combined effects allowed Zero's strength to surge dramatically.
He'd been only a single step from Ultimate-level already, and now that he finally crossed that threshold, all his accumulated potential was unleashed at once.
Naturally unwilling to accept being flattened after its glorious resurrection, the giant devil wobbled back onto its feet, trying desperately to launch a counterattack.
But Zero, diving from above with his Booster Wings deployed, crashed viciously into the devil's body, pushing it all the way back into the sky.
The devil realized its danger too late, struggling fiercely to escape—but Zero's grip was absolute, pinning it in place.
Soaring high above, Zero carried the devil into the clouds, ensuring no collateral damage below. Pressing his Giga Destroyer directly against the devil's chest, energy began to surge and gather, as the Booster Wings behind him erupted into a brilliant corona of blazing light…
If even death won't destroy you, then…
"…Return back to 'ZERO'!!!"
