Inside the old, battered RV.
Grandpa Max wore the Mask of Anur Khufos, successfully activating it. He laughed as he spoke.
"Alright! I've got the coordinates for the Sword of Bezel. I'm driving us there now."
With that, he put the mask away and returned to the driver's seat.
"Hey, Ethen…" Ben Tennyson stared at him with blazing eyes.
"When did your alien become that handsome?!"
Ethen coughed lightly and replied vaguely.
"Maybe my aliens have multiple skins that switch automatically. That's my guess."
"Ethen!" Ben suddenly had an idea and blurted out excitedly.
"Next time you transform, let me touch you with the Omnitrix! I want to see if it can absorb your DNA!"
"…Sure." Ethen nodded, mildly curious.
In truth, it was almost certainly useless.
Ben's Omnitrix already contained the DNA of all known aliens. It wouldn't absorb duplicate DNA—especially not modified variants like Ethen's.
Still… as long as the kid was happy.
In the endless desert.
A massive, sealed temple suddenly appeared, standing silently under the scorching sun.
The RV stopped at the temple entrance.
Grandpa Max, Gwen, and Ethen searched around the temple's perimeter for a long time.
"…This is strange." Grandpa Max frowned. "I can't find any entrance at all."
"Do we have to locate some hidden passage no one's ever discovered?" Gwen asked.
"If we can't find an entrance," Ethen said calmly, stopping in place, "then we'll make one."
He raised the Knight Watch on his wrist.
"Wait!" Grandpa Max warned.
"What if it triggers traps?"
"It doesn't matter," Ethen replied flatly.
"My power ignores traps."
He tapped the Knight Watch screen, selected an alien, and pressed it.
WHOOSH!!
Golden Rider light spread outward.
A towering figure emerged—
Four Arms.
But this wasn't an ordinary Four Arms.
He wore an oversized Kuuga-style Rider armor. Even so, the armor couldn't conceal his eight-pack abs or his overwhelmingly muscular frame.
With that physique—
The massive Kuuga armor looked like a Hulkbuster suit.
"SO COOL—!! I want it!!"
Ben excitedly slapped the Omnitrix against Four Arms' body.
"DNA absorption failed. Gene bank already contains this DNA."
The Omnitrix's cold mechanical voice echoed.
"What?!" Ben nearly exploded.
"That's bullshit! I don't have this Four Arms at all! Why won't you let me absorb it?!"
Bad enough you won't help him unlock skins—
Now it wouldn't even let him collect skins?!
Four Arms clasped all four hands together and slammed them downward.
WHOOSH!!
Light surged across his body.
The red armor instantly turned deep purple, heavy and oppressive.
"Entering—"
"Kuuga: Titan Form!!"
Four Arms roared as power erupted within him—
His strength multiplied several times over… easily more than tenfold!
He stepped forward, walking toward the temple entrance.
Bang.
One massive hand rested on the temple wall.
"Everyone," he said calmly.
"Stand back."
WHOOSH!
Ben, looking utterly heartbroken, transformed into XLR8 and grabbed Grandpa Max and Gwen, sprinting far away.
The moment they cleared the area—
RUMBLE—!!!
Four Arms exerted force.
Veins bulged across his arms.
The entire temple was uprooted in an instant, flying into the air like a kicked football!
It soared dozens of meters high, flew farther and farther—
Then vanished into the distance.
Beneath it was revealed a massive hidden staircase leading deep underground.
"Alright."
Four Arms looked down the stairs, radiating invincibility.
"Let's go, Ben."
"Awesome! You're insane!" XLR8 zipped forward, even reaching out with a clearly criminal hand to touch the Rider armor.
Wow.
It felt incredible.
Inside the dim stairway.
They descended step by step.
Suddenly—
Click.
XLR8 stepped on a stone tile.
It sank like a button.
"A trap?!" XLR8 reacted instantly.
WHOOSH WHOOSH WHOOSH!!
Crossbows burst out from both walls—and even from the ceiling!
Countless arrows flooded the corridor!
WHOOSH!!
XLR8 accelerated again, dodging arrow after arrow.
"…Ah—achoo!"
Four Arms felt an itch in his nose and accidentally sneezed.
RUMBLE!!
A deep purple shockwave blasted outward!
All arrows in front of him were instantly blown apart!
Then—
Four Arms kept walking as if nothing happened.
XLR8 tossed away the arrows in his hands and snorted.
"Hmph! If I'd known, I'd have let you sneeze a few more times!"
They safely descended and reached a massive underground temple.
The interior was complex—like a labyrinth.
"I can map the whole place in ten seconds!" XLR8 said confidently.
"No need," Four Arms replied calmly.
"That's too troublesome. Watch."
He slowly extended his right hand.
Click.
The prototype tool he always carried automatically transformed into a massive hammer and dropped into his palm.
BOOM!!
Four Arms swung it violently.
The hammer flew forward—
The moment it touched a wall—
CRASH!!
The wall collapsed.
The hammer kept flying.
BOOM! BOOM! BOOM!!
Walls, obstacles, mechanisms—
Everything was obliterated!
One hammer swing literally carved a path straight through the temple!
"Follow my hammer," Four Arms said with a grin.
"We'll be safe."
XLR8 stared, eyes watery.
"Where the hell did you get that weapon?! Is this VIP treatment or something?!"
They followed the hammer until it smashed through a thick wall and flew into a vast underground chamber.
Four Arms retrieved it and looked ahead.
Inside the enormous hall stood a strange pyramid-like structure, with stairs on all four sides.
At the very top—
A divine sword was embedded.
The Sword of Bezel.
It was the same divine weapon Ethen had once seen listed in the system shop.
"A divine sword…"
Four Arms tightened his grip on the hammer and took a step forward.
"It's mine."
ROAR—!!!
A terrifying beast's roar echoed throughout the entire underground temple.
