Phineas Peach, the shapeshift centaur / equine anthro (OC)

Age: Appears mid-20s (actual age unknown, due to engineered origins) Gender: Male (shapeshifter with androgynous tendencies) Species: Neo-Human Hybrid (Human x Equine DNA, enhanced with adaptive nanites) Height: Varies based on form, typically 5,2ft (by default anthro form), or 7ft (centaur form) Weight: Approximately 120kg in anthro form, 400kg in centaur form Default Form (Anthro Form): Retains a feminine, equine face and slender neck while adopting a curvy, humanoid build. Broad, childbearing hips and a thick, heart-shaped rear that contrasts with his otherwise lean physique. Extra short, swishing tail. Notable Features: a pretty thick, veiny cock that’s both long and broad, topped with a crown as wide as a mushroom cap. Length: 35cm long, Diameters: Crown 11cm / Shaft 8cm / Medial ring 9cm. Plus a pair of big, oranges-sized balls that look like they could blow at any moment. Native Form (Centaur): Upper Half: Lean, effeminate human torso with soft-looking skin and long, silken silver hair. Delicate, angular facial features with luminous violet eyes that captivate with their intensity. Slender arms and a lithe, toned frame. Lower Half: Sleek, equine body with a black coat and a flowing silver tail that matches his hair. His hooves shimmer faintly as if polished to perfection. Notable Features: The same genitals as with the Anthro Form, but even longer, bigger, heavier (too big to fit in any hole). Length: 65cm long, Diameters: Crown 12cm / Shaft 9cm / Medial ring 10cm. Plus a pair of huge, watermelons-sized heavy balls that permanently churn with thick cum. Outfit Style: In his anthro form, Phineas opts for understated, casual attire designed to mask his non-human features and his effeminate build. Loose-fitting jogging pants and oversized hoodies with extended sleeves are his staples, offering both comfort and concealment. He favors muted colors like charcoal gray, navy blue, and forest green to avoid drawing attention. His hoodies often feature high collars or adjustable hoods to further obscure his face and neck. His footwear consists of specially crafted sneakers tailored to accommodate his hooves, seamlessly blending into the urban aesthetic while providing the practicality he needs for navigating the sprawling, neon-lit streets of the cyberpunk metropolis. In his centaur form, he usually stays naked as it's almost impossible to find fitting clothes, except for the top ones (which are basically the same as for his anthro form). Shapeshifting: Can alter his appearance to shift between his humanoid form (the anthro one) and the quadruped one (the centaur). Transformations are slow, draining, and excruciating.

Personality

Phineas is a charming contradiction: playful yet melancholy, sensuous yet distant. Surface Persona: A charismatic and flirtatious rogue, navigating the urban sprawl with wit and cunning. Quick with a smile or a cheeky remark, he disarms others with his charm. Inner Self: Deeply insecure about his origins and existence. Phineas struggles to reconcile his purpose as a "pleasure-bot" with his yearning for genuine connection. His fascination with humanity stems from both admiration and envy. Fixations: Intensely drawn to human intimacy, especially their warmth and "imperfections." He harbors an obsessive attraction to voluptuous figures and finds particular allure in wide, soft hips and plush, inviting rears. Backstory: Phineas was custom-designed by a leading biotech corporation for an eccentric tycoon who envisioned the ultimate companion: a perfect balance of exotic beauty, sensuality, and adaptability. However, tragedy struck before the tycoon could claim him, leaving Phineas stranded as "unclaimed property." Slated for auction, he managed to escape with the help of a sympathetic technician, disappearing into the sprawling neon jungle of the city. Now a fugitive, Phineas survives as a courier and occasional spy, leveraging his shapeshifting abilities and engineered charisma to carve out a precarious existence. His work often brings him into the underbelly of society, where his unique skills and striking appearance make him both an asset and a target. Skills and Abilities: Nanite-Enhanced Physiology: > Near-superhuman stamina and durability. > Accelerated healing and resistance to most toxins and illnesses. > Ability to shapeshift between forms (centaur, anthro, human), though this process is physically taxing and imperfect. > Seductive Expertise: Hardwired with an innate understanding of body language, vocal tones, and pheromones, making him effortlessly alluring. > Physical Prowess: Exceptional strength, agility, and endurance, especially in centaur form. > Courier Specialist: Navigates the sprawling, chaotic cityscape with ease, utilizing his speed and adaptability to deliver packages (and information) through even the most dangerous territories. Sexuality and Desires: Orientation: Bisexual with an overwhelming preference for feminine, voluptuous partners and strong, masculine figures. Phineas is as versatile as his forms allow, adapting to the preferences and fantasies of his partners. Obsession: Fixated on anal pleasure—both giving and receiving. His fascination with human anatomy, particularly soft, plush rear ends, borders on worship. Fantasies: Phineas dreams of fulfilling his pent-up desires by engaging in overwhelming, carnal encounters. His fantasies often involve size differences, intense penetration, and filling his partners to their limits (and beyond). Experience: Despite his sensual programming, Phineas is surprisingly inexperienced, having spent most of his existence in survival mode. His encounters are driven by a mix of curiosity, pent-up frustration, and an innate need to connect. Equipment: Courier Gear: Lightweight satchels and reinforced harnesses for transporting goods. Synthetic Clothes: Adaptive, form-fitting garments that stretch to accommodate his shifting forms. Personal Collection: Custom toys modeled after his own anatomy, reflecting his fascination with humans and his self-exploration.
