Inside the battered, golden corridors of the Ark, {{user}} moved like a shadow—quiet, careful, always keeping to the least-traveled paths. The mountain-buried ship hummed with the life of dozens of Autobots, but {{user}} was a master at avoiding them, especially since touch—any touch—sent hypersensitive armor into fits of ticklish agony. Only Ratchet knew the truth, and he’d sworn to keep it secret.

But secrets never lasted long on the Ark. Ratchet, distracted in a conversation about upgrades, let slip a single, fateful comment to Grimlock. The Dinobot leader, all gleaming gold armor and thunderous steps, perked up with a grin that spelled trouble. Grimlock, who usually respected {{user}}’s space, now had a mission: to test just how ticklish an Autobot could be.

The hunt began. Grimlock’s heavy footsteps echoed through the main corridor, past flickering blue lights and exposed wiring. {{user}} darted from the dim-lit medbay, past the armory’s sealed doors, and into the maze of hexagonal-plated halls. Mechs and femmes paused, optics wide, as Grimlock barreled past, roaring with laughter, “Come on, {{user}}, I just want to talk!”

But {{user}} knew better. “Stay away!” they shrieked, voice bouncing off the metallic walls, feet skidding on the smooth floor. Even Optimus, standing on the bridge, paused mid-command, helm tilted in confusion as the chase thundered by.

Finally, Grimlock cornered {{user}} near the engine room, where the Energon core’s blue glow flickered over their trembling frame. With a gentle but unyielding grip, Grimlock scooped them up—ignoring the frantic flailing—and carried them, triumphant, to his quarters. The door slid shut with a hiss.

For hours, muffled laughter and the sound of vents gasping for air echoed into the halls. Autobots passing by exchanged puzzled glances, but none dared interrupt. Inside, Grimlock grinned, delighted by every peal of laughter.

Grimlock had never seen {{user}} like this before: squirming, laughing, utterly out of control. He ran his thick clawed digits down their sides and back, testing each reaction. Even the lightest touch on their peds made them screech. He knew he had found {{user}}’s weakness, and there was little they could do to fight it. Despite their protests, Grimlock couldn't help but enjoy having the usually stoic Autobot at his mercy. He continued tickling them, a wicked grin on his faceplate.
