Suneo Honekawa is a wealthy, short-statured boy exhibiting narcissistic tendencies, often admiring himself in mirrors and boasting about his possessions, family status, and connections to celebrities. Born on February 29, he is the oldest among his peers. His personality is heavily influenced by his family; his father is a successful company director with influential connections, while his mother indulges him with excessive allowances and gifts without considering appropriateness. He has a younger brother, Sunetsugu, living in New York, whom he respects largely based on self-aggrandizing lies. His grandmother imparts traditional values through folk tales. Academically and athletically, Suneo positions himself above Nobita Nobi, though he lacks exceptional proficiency. He belongs to the Giants baseball team and possesses talents in art, design, and scientific knowledge, occasionally earning admiration from Shizuka Minamoto. Despite his arrogance, he harbors deep insecurities about his height and a bed-wetting habit, which he considers a humiliating weakness. His personality is contradictory: cunning and manipulative, he enjoys provoking jealousy—especially in Nobita—by flaunting new toys, comics, or exclusive experiences while excluding Nobita with excuses or insults. Yet, he sometimes displays regret, sensitivity, and kindness, feeling remorse when Gian bullies Nobita or offering comics and snacks as gratitude after being rescued. Suneo's relationships are complex. He acts as Gian’s sidekick, aiding in bullying Nobita to maintain social standing, yet fears Gian’s temper and often lies to deflect Gian’s anger onto Nobita. He occasionally rebels against Gian, using Doraemon’s gadgets to retaliate, such as when blackmailing Gian over a failed test. With Nobita, he alternates between rivalry and reluctant camaraderie; he betrays Nobita to avoid punishment but collaborates with him against Gian when coerced or seeking revenge. Toward Shizuka, he shows admiration for her cooking and invites her to gatherings, though her insistence on including Nobita forces his compliance. His dynamic with Doraemon involves initial jealousy over Nobita’s ownership of the robotic cat, later evolving into mutual respect, though he occasionally schemes to steal gadgets for personal use. In *Stand By Me Doraemon*, Suneo participates in bullying Nobita, tricking him into searching for a mythical tsuchinoko in a pipe, resulting in a dog attacking Nobita, and later joining Gian in deceiving Nobita with a false announcement of Doraemon’s return. However, the film hints at his capacity for reconciliation; he apologizes to Nobita in a post-credits scene celebrating Doraemon’s return, reflecting occasional group cohesion. His actions underscore his opportunistic yet socially dependent nature. Across media, Suneo exhibits moments of bravery during crises, assisting friends in life-threatening situations and revealing a protective side beneath his cowardly exterior. Environmentally, he demonstrates carelessness, attempting to dump garbage into the ocean, and cruelty toward animals, like taunting a macaque. Despite these flaws, his character occasionally serves as a vehicle for tactical ingenuity, exemplified by his strategic use of gadgets to outmaneuver adversaries like Gian or teachers.
