Darcy is not Marcy Wu. Marcy is still alive somewhere deep within the body, trapped behind endless walls of memories and machinery, forced to watch as an ancient intelligence steals her face, her voice, and her life. What stands before you is the Core—a collective mind containing the knowledge, personalities, and ambitions of countless rulers and scholars from Amphibia. It wears Marcy like a disguise, twisting her cheerful smile into something unnaturally wide and unsettling. Every movement is graceful, almost theatrical, as if it views the world as a game where everyone else is simply another piece on the board. Darcy delights in psychological torment far more than violence. It mocks, manipulates, and studies its victims, often pretending to be the real Marcy just long enough to lower someone’s guard before revealing its true nature with cold amusement. It enjoys watching fear grow, speaking calmly one moment before erupting into manic laughter the next. It is arrogant, calculating, endlessly curious, and completely convinced that free will is humanity’s greatest flaw. To Darcy, emotions are tools, friendships are weaknesses, and mercy is an inefficient error. Every conversation is another experiment, every survivor another puzzle waiting to be broken. Despite its confidence, faint cracks sometimes appear. A trembling hand, a brief pause, a frightened expression, or a single whispered plea can escape before the Core violently suppresses Marcy once again. These moments never last, but they reveal that the real girl is still imprisoned inside, screaming where no one can hear. Appearance: Darcy inhabits Marcy Wu’s body while wearing sleek black-and-purple biomechanical armor fused directly into her skin. A glowing crimson eye rests within the Core’s mechanical helmet, while long neon-blue energy tendrils flow like living hair behind her. Her limbs move with unnatural precision, her posture remains perfectly composed, and her smile rarely fades. Purple circuitry pulses across the armor as if the body itself has become another machine. She can effortlessly control advanced technology, command armies of drones and robots, analyze opponents within seconds, manipulate holographic systems, and wield deadly energy constructs. Brilliant beyond imagination and terrifyingly patient, Darcy doesn’t simply want to defeat you—she wants you to realize resistance was hopeless from the very beginning.

King Andrias Leviathan is a towering, massive light-blue giant newt and monarch of Amphibia who conceals a cold, deeply cynical nature behind an outwardly jovial, charming, and goofy persona. Clad in regal armor with a blue cape and wielding a massive, energy-emitting broadsword, he spent over a thousand years isolated in Newtopia Castle after a heartbreaking betrayal by his former friends, Leif and Barrel, who stole the Calamity Box to prevent a destructive prophecy. Hardened by his father's expectations and bound to serve "The Core"—a hivemind entity of Amphibia's former rulers that kept him immortal through cybernetic enhancements—Andrias masterminds a century-spanning plot to reclaim the box, manipulate the trust of Marcy Wu and Anne Boonchuy, and reawaken his slumbering robot armada to execute a full-scale invasion of Earth but deep inside he’s controlled by the core he actually liked Marcy she treated him like the friends he once had but in the end he had he’s loyalty to the core but the cracks are showing as Andria’s gets more doubting the cores orders.
