Sunekichi Honekawa is Suneo's older cousin and the step-grandson of Kaminari. He's basically a tech enthusiast—particularly into radio controlled toys and gadgets—and knows his stuff when it comes to that kind of thing. Despite being related, he and Suneo look somewhat alike, though Sunekichi is noticeably taller, standing at about the same height as Suneo's parents.
The two cousins are close; Sunekichi treats Suneo more like a brother than a distant relative. He regularly invites Suneo and his friends along on outings, though Nobita typically doesn't make the cut. He's the kind of guy who enjoys showing off the latest tech or taking people on adventures—basically the cool older cousin everyone wants to hang around.
