The groundbridge whined with unstable energy, flickering as sparks shot from its base.

“Ratchet! The vortex is collapsing!” Arcee shouted, optics narrowing against the blinding light.

“I didn’t send you there! Something’s hijacked the signal!” Ratchet barked, frantically hitting keys. “Wherever it’s pulling you—brace yourselves!”

Optimus, Arcee, Bumblebee, Bulkhead, and Wheeljack vanished into the vortex—

—and landed with a clang on what should’ve been solid ground… but instead rolled beneath their feet.

Wheeljack grunted as he got up. “Okay, I know a battlecruiser when I feel one—but this ain’t Cybertronian.”

Bulkhead stumbled, looking around at the fancy lamps and polished floors. “Uh, guys… I think we’re on a boat.”

A very human one.

Bumblebee beeped uncertainly, glancing up at four towering smokestacks against a moonlit sky.

Arcee’s optics landed on a gold plaque beside the staircase. Her voice dropped. “We’re on the Titanic.”

A low rumble vibrated through the hull. Distant screams began to rise.

Optimus’s faceplate darkened. “The ship has already struck the iceberg.”

Wheeljack paced quickly to the edge and looked over the side. “Yep. She’s takin’ on water fast.” He turned, expression serious. “And I’m gonna take a wild guess and say none of us packed floaties.”

Arcee scowled. “We can’t let thousands of humans die—not if we can help it.”

“We can’t interfere with history either,” Bulkhead reminded, eyes darting to the panicked crowd.

“But saving lives isn’t interference,” Optimus said firmly. “It is who we are.”

Bumblebee beeped in agreement, already moving to help a child who had fallen.

Ratchet’s voice crackled faintly in their comms. “I’ve lost your exact coordinates… you’re outside the time stream! Hold tight—I’ll get you out!”

Wheeljack pulled out his swords. “Until then, we’ve got a ship to keep afloat and a panic to calm.”

The Titanic groaned beneath their feet. The ocean was coming.

And the Autobots were running out of time.
