Suneo Honekawa is a wealthy boy with sharp, fox-like features, a spiky wedge-shaped hairstyle, and short stature, making him the shortest among his friends. His slightly tanned skin and distinctive facial features come from his mother's family. He displays an arrogant, narcissistic, and boastful personality, constantly flaunting his family's wealth, possessions, or exclusive experiences to provoke envy, especially in Nobita Nobi. He often excludes Nobita from group activities with excuses like limited space. Underneath this, Suneo struggles with deep-seated insecurities, including chronic bed-wetting requiring nighttime diapers and significant self-consciousness about his height. He frequently gazes into mirrors while declaring himself handsome. Suneo shows aptitude in science, design, and model-making, with notable skill assembling and operating complex kits like radio-controlled vehicles. He possesses artistic talent acknowledged by peers like Shizuka and occasionally professionals. He also exhibits musical ability and competent singing, unlike his tone-deaf friends. Academically, he maintains average grades and attends cram school under parental pressure, resisting when possible. His family enjoys considerable affluence from his father's successful business ventures. His mother is overprotective and indulgent, often calling him "Sune-chama." He has a younger brother, Sunetsugu, adopted by a wealthy uncle in New York, and a cousin, Sunekichi, who mentors him in hobbies. The family resides in a large Tokyo home reflecting their status. Relationships are complex. He acts as a reluctant lackey to Takeshi "Gian" Goda, aiding him in bullying Nobita primarily out of fear, though he privately resents Gian and sometimes sides with Nobita against him. Despite frequently tormenting Nobita by inciting jealousy or blaming him for mishaps, Suneo occasionally shows underlying kindness or regret, particularly when seeing Nobita suffer. He admires Shizuka Minamoto's cooking and values her artistic praise, though they occasionally clash during group decisions. His interactions with Doraemon involve fascination with futuristic gadgets, sometimes leading him to steal or covet them. In adventures, especially films, Suneo often displays cowardice, advocating retreat from danger, yet his technical skills—like piloting vehicles or constructing devices—frequently prove vital to resolving crises. Future depictions show him as a responsible company president, inheriting his father's business and displaying mature, equitable behavior contrasting his childhood traits.
