The Diamond Giant's eyes hardened as it grabbed Way Big by the leg and slammed him viciously into the ground.
Boom.
The whole of Mount Rushmore shook violently, as if the world were ending, the impact thunder echoing deafeningly through the air.
"Hehe~ so Way Big's nothing special after all."
Ghostfreak emerged from the void and thrust his bone-white claws toward Way Big's head.
"You reckless fool."
Way Big struck out with a palm and instantly swatted Ghostfreak away like a fly, displaying overwhelming divine strength.
But the Diamond Giant naturally wasn't about to sit there and wait. It raised one enormous foot, and dense, razor-sharp spikes burst from the sole, like a burial ground of blades, pressing down on Way Big with a terrifying aura.
Way Big's eyes flashed with sharp light.
He sensed the threat of death!
Whoosh.
Way Big flipped over and launched himself into the air like a nimble swallow, darting up high above the battlefield to look down on the massive monsters below.
Flight!
This had originally been an ability of Ultimate Way Big, but because Way Big had saved two helicopters last time, it had awakened early.
Way Big might not be as strong as those two monsters, but with the power of flight, he might still have a chance.
Ben 10,000's Way Big, however, was having a much harder time...
He didn't have the ability to fly, and under the combined assault of the Demon Bull Giant and Kevin 11,000, he was being forced back step by step, miserable and on the verge of collapse.
The Demon Bull Giant stood a hundred meters tall, twice the size of Way Big, and was immensely powerful. Every punch it threw carried the force to shatter mountains.
Together with the savage Kevin 11,000, it pushed Way Big into immediate danger.
"Ben Tennyson, today we finally settle this once and for all!" Kevin 11,000 flapped his flaming wings and hovered in midair, already convinced victory was his.
Way Big gave a cold snort and barely managed to block the Demon Bull Giant's fist. "Don't celebrate too soon. Evil can't defeat justice!"
In the next second, he transformed into Buzzshock.
"Hehe!"
Buzzshock giggled, tadpole-shaped green currents swirling around his body as he drove his energy to the limit.
Crackle!
Ferocious green lightning spread like sky-covering vines, crossing over one another as it pressed down on Kevin 11,000 and the Demon Bull Giant with scorching force.
In an instant, a towering cage of lightning took shape on Mount Rushmore.
Kevin 11,000 didn't move. He simply turned his head, his flaming eyes fixed on the Demon Bull Giant with a grin.
Breaking the cage was dirty work. He could leave that to the monster.
After all, it had no mind to speak of.
"Roar!"
Sure enough, the moment it realized it was trapped, the Demon Bull Giant flew into a rage and slammed its black demonic claw straight into the surging current.
Crackle!
The lightning cage flashed violently, green light bursting in every direction.
The Demon Bull Giant's body convulsed violently, its eyes even rolling back for a moment, but it quickly recovered and tore the cage apart by force.
The green lightning cage broke into countless specks of energy that scattered through the sky before fading into the air.
The Demon Bull Giant clenched its fists and let out a savage roar.
But at some point, Buzzshock had already disappeared.
The Demon Bull Giant scratched its head and stood there blankly, momentarily at a loss.
"Where is he?" Kevin 11,000 looked around, suddenly a little rattled.
Compared to Ben Tennyson's alien forms, what he feared more was Ben Tennyson's unpredictability.
Those traits should have faded long ago as Brother Ben got older, but with young Ben's arrival, it seemed Brother Ben had somehow returned to his old self...
"What are you looking at? I'm right here!"
A hoarse voice came from behind him.
Kevin 11,000's body stiffened. He whipped his head around, only to get punched in the eye by Stinkfly.
Bang.
Kevin 11,000 dropped straight to the ground and slammed into it with a thunderous crash.
But then a giant black hand suddenly reached from behind and grabbed Stinkfly.
The Demon Bull Giant stared at the tiny insect in its grasp with scarlet eyes. The pressure it gave off was like facing a towering mountain.
Stinkfly gritted his teeth, turned into Grey Matter, and instantly slipped free.
Then he transformed into Cannonbolt, spinning at high speed and crashing toward the Demon Bull Giant's face with terrifying momentum.
The Demon Bull Giant swatted him away with one slap. The overwhelming force sent Cannonbolt flying hard into the muddy ground.
"Damn it, how can something this strong even exist..." Cannonbolt returned to human form, struggled to his feet, and looked up at the sky-blocking Demon Bull Giant.
That kind of power was terrifying. In terms of raw strength alone, it far surpassed Way Big...
Whoosh.
Another slap came crashing down.
Cannonbolt tried to escape, only to realize his whole body had gone weak. That last blow had already badly injured him.
Just as the terrifying black hand was about to flatten him into paste, a sharp hammer-spear shot in from the side with a howling gale and smashed into the Demon Bull Giant's neck.
Thud.
The Demon Bull Giant's tough hide was actually split open. The wound wasn't deep, but blood still seeped out.
The giant demonic hand withdrew at once. Clutching its wounded neck, it let out a shrill howl.
"Cuz."
Cannonbolt's face lit up with delight when he saw who had arrived.
A towering robot appeared in the sky.
Its entire body was covered in snow-white armor with a cold metallic sheen. Its eyes glowed cyan, and a golden helm set from the brow to the forehead gave it the look of a crown, radiating nobility and dominance.
Its blood-red Emperor claws reflected a razor-sharp chill beneath the blazing sun.
Barbatos Lupus, Emperor Form!
"That's a big one. Looks tough," Future Lucian said, pushing up his glasses with the faintest smile. "But... that just makes it more fun."
"Barbatos, we finally found a strong opponent. Let's make the most of it."
At those words, Barbatos's eyes blazed crimson. Its power output surged to the limit, crackling all over with arcs of electricity.
"Ben, Kevin 11,000 is yours. I'll handle this one."
As soon as he finished speaking, blue flames burst from Barbatos's back. The powerful thrust launched it forward in an instant, flashing straight to the Demon Bull Giant's front.
"Cuz, you're still just as crazy as ever," Cannonbolt said with a bitter smile.
Future Lucian might usually seem gentle and refined, but in battle he was a complete maniac.
And with that brilliant mind of his, he had built countless high-tech weapons. The Barbatos in front of them was the best proof of that.
By now, the Demon Bull Giant had recovered and was roaring furiously at Barbatos.
Even though Barbatos stood nineteen meters tall, in front of the hundred-meter Demon Bull Giant, it was nothing more than a slightly bigger bug.
One kick would be enough to deal with it.
"Hey, big guy. Let's have some fun." Barbatos's eyes burned red, overflowing with fighting spirit.
With a swing of the hammer-spear in its hand, the four sharp blades at the front spun wildly. Barbatos raised it high and brought it smashing down at the Demon Bull Giant's head...
