Suneo Honekawa, a core character in the Doraemon series, hails from a wealthy family. He receives roughly ¥5000 monthly in pocket money, which he uses to buy expensive toys, gadgets, and comic books, often flaunting these possessions to provoke envy, especially in Nobita. His father's success as a company president underpins the family affluence, a point Suneo proudly references while aspiring to inherit the business. His family includes an indulgent mother, a younger brother (Sunetsugu) living in New York with an uncle, a grandmother who shares folk wisdom, and a similarly wealthy cousin, Sunekichi. Physically, Suneo is short and very thin, with black hair, large black eyes, and distinctive fox-like facial features inherited from his mother. He is acutely self-conscious about being the shortest boy in his class. A deeply embarrassing secret is his bed-wetting, requiring him to sleep in the bathroom and wear diapers at night, which he views as a major personal failing. Suneo's personality displays contradictions. He exhibits pronounced narcissism, frequently admiring himself in mirrors and declaring his own handsomeness. He is cunning, prideful, arrogant, and possesses a strong tendency to brag about his possessions, connections, and family status. He often excludes Nobita from invitations to Gian and Shizuka, using weak excuses or insults, and readily allies with Gian to bully Nobita, sometimes taking pleasure in undermining Nobita's self-esteem. He demonstrates cruelty towards animals and disregard for the environment, like attempting to dump garbage into the ocean. Despite these traits, Suneo possesses notable intelligence, extensive scientific knowledge, and significant artistic and design talents acknowledged by Shizuka and others. He demonstrates strategic thinking, effectively using Doraemon's gadgets for complex plans involving revenge or personal gain. Beneath his arrogant exterior, he harbors a sensitive and caring side, occasionally feeling genuine remorse when Gian bullies Nobita and showing kindness, such as offering Nobita comics and snacks after being rescued. He exhibits fear and cowardice, often being the first to suggest retreat in dangerous adventures and typically crying for his mother during significant pain or humiliation. His relationship with Gian is complex; while acting as Gian's sidekick and praising him to avoid conflict, he secretly fears and dislikes him, often blaming Nobita to escape Gian's wrath. Gian sometimes bullies Suneo or exploits him, like consuming his food during study sessions. Regarding Nobita, Suneo functions as both an arch-rival, provoking his jealousy, and an inconsistent friend. Their dynamic involves frequent conflict and betrayal, but also moments of camaraderie and alliance, particularly when uniting against Gian's bullying. He maintains a generally positive relationship with Shizuka, who admires his artistic skills, though they can argue over issues like animal ethics. Shizuka has pressured Suneo into including Nobita on outings. With Doraemon, Suneo is considered a good friend. While initially jealous of Nobita having a robotic cat, he develops his own friendship with Doraemon and seeks his help during crises, though he also attempts to steal gadgets for personal use. Across the series, including films and specials, Suneo often transitions from his usual self-centered and sometimes cowardly behavior into a more supportive and brave team member when his friends face genuine peril, highlighting his internal conflict between ingrained flaws and underlying loyalty during adventures.
