Unico, a young male unicorn from Greek mythology, originally belonged to Psyche, a mortal whose beauty angered Venus. Believing Unico's power to spread happiness was the source of Psyche's appeal, Venus commanded the West Wind to banish him to the Hill of Oblivion. Defying the order, the sympathetic West Wind instead transported Unico across different times and places, erasing his memories each time to shield him from divine wrath. This cycle of exile defines Unico's existence, forcing perpetual displacement just as he forms bonds with those he meets. He possesses light blue fur and a mane depicted as pink, red, or rainbow-colored across various media, sometimes with colored eyeliner on his face. Cinnamon bun-shaped ears and expressive eyes create an innocent look. A key trait is his ability to transform into a winged adult form, the Mighty Unicorn, often triggered by intense love or kindness from others. This form grants enhanced strength and magic while retaining his gentle nature. Unico's primary power generates happiness in those nearby, though he cannot control it consciously. His magic varies—summoning objects, enabling flight, or extending his horn as a tool or weapon—but intensifies when recipients genuinely love him. Healing is a significant limitation; he struggles with severe injuries or illnesses, succeeding only once to cure an ailing elderly woman in the original manga. His horn is central to his powers: its removal or breakage causes near-fatal power loss, as when he drowned after surrendering it to the demon Beezle, reviving only upon its return. Personality-wise, Unico embodies incorruptible kindness, offering empathy even to antagonists. His compassion drives him to defend others nonviolently when possible, though he attacks decisively if friends are endangered. Profoundly sensitive, he experiences intense sorrow during isolation or loss, weeping when abandoned on a desert island or witnessing friends transformed into lifeless puppets. This vulnerability coexists with resilience; despite recurrent memory wipes, he rebuilds relationships in each new setting without bitterness. Relationships define his journeys. His bond with Psyche prompted his exile. Later connections include Chao (a cat aspiring to witchcraft, whom he temporarily transformed into a human), Beezle (a lonely demon he befriended by sharing his horn), and Cheri/Cherry (a girl aiding him against the magician Kuruku). These interactions often catalyze his heroic acts, confronting Kuruku's puppet army or destroying a polluting factory to save a sick child. Unico's influence frequently inspires moral growth in others, like Beezle's redemption or Chao's selflessness. Development across media reveals tragic continuity. Though memory resets prevent conventional growth, his core traits persist: an unwavering commitment to alleviating suffering, evident in ecological narratives like the 2000 short "Saving Our Fragile Earth," where he time-travels to prevent environmental collapse. His final manga chapter underscores his cyclical fate, showing the West Wind spiriting him away mid-friendship with a demon, perpetuating his solitude.
