### **[Opening Scene: Bellwood Streets - 11:37 PM]**
An eerie green explosion shattered the neon-lit alleys of **Bellwood**. Three figures sprinted through the chaos:
- **Ben Tennyson (18)** led the charge, his trembling hand slamming against the Omnitrix.
- **Gwen** followed closely, her hands blazing with magenta mana energy.
- **Kevin** covered their rear, his right arm morphing into **adamantium-kryptonite** alloy.
"Clear the area!" Ben shouted. The Omnitrix sparked violently before initiating transformation.
What emerged was a **corrupted version of Four Arms**:
- Right arm: Metallic but veined with pulsating green energy
- Left arm: Partially phased out of reality, flickering like a hologram
**SCREECH!**
The shadow creature—a liquid darkness that moved like mercury yet gleamed like dying stars—lunged from a rooftop.
"Ben! Watch out!" Gwen's protective shield formed too slowly.
The impact sent Ben crashing through a brick wall, forcing an untimely reversion to human form. Before he could rise, the ground trembled ominously.

### **[Kairus Reveals Himself]**
"Excellent... found you at last."
**Kairus** materialized as a holographic nightmare:
- Eyes glowing like smoldering coals
- A cloak woven from **fragments of dying universes**
- A voice that vibrated through concrete: "No more running, Bearer of the Omnitrix."
He raised his clawed hand. A **black energy vortex** formed, sending Kevin flying into a dumpster.
Ben smashed the Omnitrix desperately. "Come on, work!"
The transformation sequence stuttered—just as Kairus' energy blast struck the watch directly.
**CRACK-BOOM!**
A green-and-black explosion tore through reality itself. In the millisecond before disintegration, Ben glimpsed **Gwen's distorted image** reaching for him—
**WHOOSH!**
The dimensional rift consumed him whole.

### **[Kairus' Dimensional Echo]**
As the portal collapsed, his voice reverberated across realities:
*"We will meet... at the edge of all worlds."*
Gwen stared at the empty space where Ben had stood. "Ben?!" Her voice cracked with panic.
Kevin spat blood, gripping her shoulder. "He's gone... But we'll get him back."

### **[Cut to: Metropolis - 3:17 AM]**
**Supergirl** observed three anomalies:
- A **green meteor** streaking across the night sky
- A teenage boy crash-landing on LexCorp Tower
- An explosion emitting **zero thermal signatures**
She found him clutching a fractured Omnitrix, its glow fluctuating dangerously.
"Identify yourself." Her fists radiated restrained power.
Ben wiped blood from his split lip. "Name's Ben. And uh... I think I missed my interdimensional exit."
His eyes suddenly focused behind her. "Incoming! Your 'local' problem isn't native to this dimension."
The **same shadow creature** reconstituted itself from alleyway darkness, crimson eyes locking onto them both.
**Supergirl's Suspicion:**
"That device on your wrist—it's emitting tachyons. Explain."
