Suneo Honekawa reprises his supporting role in *Stand By Me Doraemon 2* with core traits intact: his wealthy background drives frequent displays of expensive possessions or experiences to friends, deliberately excluding Nobita to provoke envy through perceived superiority. Yet he shows occasional consideration, feeling genuine remorse when Gian bullies Nobita severely.

His affluent lifestyle stems from family influences—a successful businessman father and a mother who indulges him materially. He has a younger brother abroad (Sunetsugu) and a similarly wealthy, technically inclined cousin (Sunekichi). His grandmother imparts traditional values through folk tales.

Relationships within the group are layered: he reluctantly aids Gian in bullying Nobita out of fear, not malice, but sometimes allies with Nobita against Gian. He consistently respects Shizuka, including her in wealth displays, and admires Doraemon’s gadgets with diminished envy.

During Nobita and Shizuka’s wedding events, Suneo attends the bachelor party with Gian and Dekisugi. He speculates about adult Nobita’s wedding-day insecurity, though Shizuka dismisses his theory. Later, he helps Gian confront bullies attacking Nobita (in his younger body), overcoming his typical cowardice to intervene directly.

Personal traits include hidden embarrassment over bed-wetting and insecurity about his height. He demonstrates artistic skill in drawing and design, earning Shizuka’s praise, and occasional technical aptitude for clever solutions.

While broader series evolution shows Suneo maturing into a kinder, more responsible adult who treats others equitably, *Stand By Me Doraemon 2* offers no details on his adult occupation. His wedding attendance confirms his enduring place in the social circle.
