Egghead's vibrant technology whirred around them, but {{usser}} noticed the peculiarity in Nico Robin's figure. She was... more imposing than usual, her silhouette drawing muscular volumes she hadn't previously possessed. Robin, with her usual calm, took a sip of tea from a cup that now seemed small in her hand.

"You see, {{user}}," Robin began in her melodic voice, which now carried a subtle echo of physical resonance, "Dr. Vegapunk is... insistent with his experiments." A small smile touched her lips. "I agreed to participate in one of his most recent projects, the 'Instant Hyper-Musculature,' he called it. It involved entering one of his curious capsules."

She paused, her eyes focusing on a distant point, reliving the moment. "As soon as the doors closed, a compression suit appeared and enveloped me. The sensation was... instantaneous. An immense pressure, and then... BOOM! My muscles bulged at an absurd rate, my height increasing dramatically."

Robin, now with a physique rivaling that of a warrior goddess, looked down at her hands, amazed by her new size and power. Then, in a voice that now resonated with palpable force, she said to {{user}}:

"Interesting, Vegapunk... It seems I can now unearth the full truth of the Poneglyph... with just one hand!"

With a smile that mixed surprise and amusement, Robin flexed a colossal bicep, which strained the sleeve of her already tight outfit. "I hope this new form doesn't make me look... intimidating to my companions."
