OVA
Description
Melona is one of the primary servants of the Swamp Witch, serving as a key antagonist throughout the Queen's Blade narrative and appearing in the OVA series Queen's Blade: Beautiful Warriors. Often referred to as the Protean Assassin, she is not a typical human but an amorphous, shapeshifting slime entity crafted by her mistress to act as an intelligence operative and an agent of chaos.

Her origins lie in her unwavering loyalty to the Swamp Witch, having been created to infiltrate and destabilize the Queen's Blade tournament on her master's orders. While her primary mission is to cause confusion and spread discord, her methods are driven by a deeply ingrained, cruel sense of amusement rather than pure efficiency. She finds genuine pleasure in playing cruel pranks and devising strategies aimed at terrifying and humiliating her opponents, often opting for the most shocking and theatrical method available.

Melona’s personality is a blend of childishness and sadistic cruelty. She speaks and acts with a playful demeanor, yet she revels in psychological warfare, enjoying the fear and confusion she instills in others. She is seductive, alluring, and manipulative, but with a notable vulnerability; despite her monstrous nature, she despises being called a monster and reacts with extreme hostility, such as attempting to slowly strangle someone for the insult. While typically an agent of chaos, she is not entirely unreasonable and is willing to form temporary alliances with her enemies if doing so serves her own needs and furthers her goals.

Physically, Melona is defined by her unique composition. Her body is a pink, metamorphic slime that is soft and moist but can instantly harden to aid in attacking or defending. Her most commonly seen form is that of a well-endowed woman with luminous pink skin, blue eyes featuring distinctive clover-shaped pupils, and long pink hair styled with bunny-like protrusions. Her wardrobe is scant and translucent, often accented with eye-like pauldrons, a winged heart emblem, and using the hand-like bangs of her hair to cover her chest.

Her role in the story is that of a recurring antagonist and direct agent of the Swamp Witch. She is the strongest of her minions and is deployed to sow chaos. Throughout the tournament, she uses her abilities to attack key characters, gather information, and eliminate obstacles to her mistress's plans. She is directly responsible for summoning the Great Snake Demon to attack combatants at the Gainos Bridge. Over the course of her appearances, Melona shows a degree of development. In Queen's Blade Rebellion, after absorbing a certain ancient demon, her knowledge and judgment increased significantly, making her not only powerful but also a brilliant strategist capable of engineering world-shaking conspiracies. Her design also evolves slightly in this arc, with her wardrobe becoming more elaborate, featuring frilly, elbow-length sleeves and a floor-length skirt. Later narrative developments hint at a potential shift in allegiance, with dialogue suggesting she may decide to leave the Swamp Witch's service, having discovered the truth about the queen.

Melona boasts a wide array of fearsome abilities stemming from her slime composition. Her core power is shapeshifting; she can alter her shape, texture, and color to flawlessly mimic other people, including their clothes, weapons, and armor. Her mimicry is so precise that she can even imitate the combat techniques of those she copies, though her replicated versions are not as powerful as the originals. This amorphous nature grants her practical immunity to physical attacks, as blades and blunt force merely pass through or squish her malleable form without causing lasting harm. She can also absorb small organisms into her mass, allowing her to increase her strength and size indefinitely, theoretically becoming invincible.

Another of her signature abilities is the use of her breast milk. By using the goo-like arms formed from her hair to squeeze her breasts, she can fire this milk for various effects. When sprayed, it acts as a fast-acting corrosive agent that dissolves clothing, armor, and even buildings, leaving opponents disoriented and humiliated. When fired in concentrated bursts, it functions as a high-velocity explosive. However, this ability has a notable weakness; if the milk is blocked before it can be fired, it causes Melona to implode violently, a risky but effective countermeasure. Despite her durability, a sufficiently powerful blow can temporarily disable her, allowing an opponent to snatch away parts of her mass, reducing her size and power and forcing her to retreat and regenerate. She also possesses a highly developed sense of smell, capable of recognizing individuals by their scent, and her eyes can flash yellow with a power that can momentarily paralyze her foes.
