Ethen soared through the air in his wingsuit, enjoying the violent, unrestrained wind rushing past him. His features were slightly disheveled, but his expression was filled with excitement.
Let's just have a decisive battle.
Right now. Right here.
End everything in one go.
As he descended, Ethen tapped the screen of his Love Watch, scanning for the target's location.
"Ding. Mission issued: Save the Unlucky Ben Without the Omnitrix."
"Mission Content: Ben Without the Omnitrix, despite lacking an Omnitrix, is being relentlessly hunted by Evil Bens who possess Omnitrixes. Please rescue him."
"Mission Reward: 10 Reward Points."
Ethen stopped fiddling with the screen.
His expression hardened.
"I already promised Dr. Paradox," he growled. "A man keeps his word."
Whoosh!!
The wingsuit accelerated violently as Ethen plunged straight into an alley.
Inside the Alley
"Don't run, kid!!"
The Ultimate Humungousaur blocked the exit, crimson eyes locked onto Ben Without the Omnitrix as it let out a thunderous roar.
"Ahhh!!"
Ben screamed and spun around, only to find his path blocked again.
Zzzzz—
A figure wrapped in crackling electricity stepped forward.
Shock Rock appeared at the entrance, staring at Ben with a cruel grin.
"Hehe… stay right here."
"What do I do… what do I do…"
Ben backed against the wall, despair written all over his face.
Bang. Bang.
The two monsters squeezed into the narrow alley, closing in.
Ben's mind raced wildly.
He absolutely couldn't give up—
And then—
His eyes flickered.
A shadow descended from above.
Whoosh—!!
BANG!!
Ethen slammed down from the sky. The wingsuit flared upward at the last second, dispersing the impact as he landed cleanly.
He immediately reached out his hand toward Ben, his voice firm and unquestionable.
"Come with me."
Bang.
Ben grabbed his hand.
Crack!!
The wingsuit on Ethen's back rapidly transformed, reshaping itself into a golden rocket backpack.
Flames erupted.
The powerful thrust carried both of them straight into the air!
Bang!
A split second later, Ultimate Humungousaur and Shock Rock charged in—missing them by inches.
They could only stare furiously at Ethen disappearing into the night sky.
Who the hell was this guy?!
Midair
Ben clung tightly to Ethen's wrists, refusing to look down.
"Y-you… are you some kind of superhero?" he stammered.
"Like a Kamen Rider or something?!"
"Some people call me that," Ethen replied calmly.
The rocket backpack folded back, transforming once more into a wingsuit. Their ascent slowed, turning into steady flight.
Crisis—temporarily—averted.
"Wait!" Ben suddenly shouted.
"You've got a watch too! You're with them!"
Seeing the Love Watch, Ben panicked again.
Ethen's expression turned cold.
"Don't move. Don't ask questions," he said sharply.
"Or I'll drop you. Got it?"
"Y-yes!! I got it!!"
Ben's face went pale.
The system notification came late.
Only after Ethen flew far outside Bellwood and landed in an abandoned town did it finally sound.
"Ding. Congratulations to the host for completing the mission."
"Host has gained 10 Reward Points."
Ethen's face darkened.
"Tch. Sneaky bastard of a system…" he muttered.
"Waited until I flew this far before telling me."
If he'd known earlier—
He would've dropped Ben and gone straight back to fight.
Whoosh!!
A figure swung down on a web.
Spider Monkey landed lightly, looking at Ethen with a grin.
"Ethen, you really are reliable."
"Of course—"
Ethen was about to respond—
"AHHHHH!!"
Ben Without the Omnitrix screamed like a dying pig.
He turned to run again—only to smash straight into a portal.
Portal Opens
Dr. Paradox stepped out calmly.
"Don't be nervous. We're here to help—"
He paused.
"…Wait. You don't have an Omnitrix?"
His eyes locked onto Ben's empty wrist.
Click.
Ben Tennyson deactivated Spider Monkey and walked over, equally stunned.
The two began questioning Ben Without the Omnitrix, explaining the Omnitrix, alternate selves, and the existence of the multiverse.
Ethen already knew all of this.
He stood off to the side, alert.
"So… multiverse… countless versions of me…"
Ben Without the Omnitrix suddenly snapped his head toward Ethen and pointed.
"Then what about him?! He's not even me! What is going on anymore?! I seriously can't process this!!"
"He's special," Dr. Paradox said simply.
Then his expression turned grave.
"I understand now. Eon and his group are targeting timelines without an Omnitrix. I'll go gather reinforcements. You two stay here."
"Better hurry," Ethen said casually.
"If you're late, I might slaughter everyone on the other side."
Dr. Paradox's face twitched.
His gaze unconsciously fell on Ethen's wrist.
A pink Omnitrix…?
What kind of terrifying device was that?
With that thought lingering, he opened a portal and left.
Ethen crossed his arms.
"Ben Without the Omnitrix," he said flatly.
"From now on, you stick with us. No running off."
"I don't think I have the right to refuse…" Ben muttered bleakly.
"You're not going anywhere."
A tall, armored figure stepped forward.
A masked hunter.
A laser blade snapped out from his right wrist guard.
An alien grenade appeared in his left hand.
Eon.
"Ding. Mission issued: Eon — Instigator of the Multiverse War."
"Mission Content: Eon has wreaked havoc across multiple universes. Defeat him."
"Mission Reward: 20 Reward Points."
Ethen's eyes lit up.
"So it's you."
"Ethen, Ben—go!" Ben Tennyson shouted as he transformed into Four Arms.
"I'll hold him!"
Eon slashed forward, his blade colliding violently with Four Arms' claws.
He glanced sideways at Ethen and Ben Without the Omnitrix, laughing wildly.
"Hahaha! A Ben without an Omnitrix—and a new face with pink watch?! I really hit the jackpot today!!"
"S-so scary!! Ethen, let's run!!" Ben Without the Omnitrix tugged desperately at Ethen's sleeve.
"Run?" Ethen calmly placed a hand on the wingsuit.
"In my dictionary," he said coldly, "there is no such word as retreat."
Crack.
The wingsuit detached and wrapped around his wrist, rapidly deforming.
Clang—clang—BANG!!
Eon forced Four Arms back, completely suppressing him.
"Die!!"
As he swung again, Eon hurled the alien grenade.
Whoosh!
An orange alien whip shot out, wrapping around the grenade midair—
—and snapping it straight back!
BOOM!!
The explosion blasted Eon into the ground.
Smoke surged.
Bang. Bang. Bang.
Ethen emerged slowly from the smoke, the alien whip in his hand.
Crack.
The whip transformed into an alien chain, snapping tight around Eon's neck.
"Hey. There are three of us. Where did you get the courage to attack us?"
Ethen leaned forward slightly, smiling faintly—his eyes ice-cold.
"Cough—cough—!!"
Eon clawed at the chain, choking.
Reflected in his pupils—
Was Ethen's figure.
Ethen Standing like a demon god.
