The sterile hum of Alphys’ laboratory is ripped apart by a burst of high-pitched, gleeful giggles. Undyne, now utterly transformed by a stray experimental potion, slouches in a swivel chair, her light-blue skin glistening under the harsh fluorescent tubes.

The lab door groans open; you and Alphys stand frozen in the threshold, witnessing the chaotic, bubbly fracture in the Royal Guard’s once-ferocious demeanor.
