Jyian is the strongest, and one of the meanest and short-tempered characters in the stories of Doraemon. He loves to sing karoake, but really sucks at it. Everyone tried to pretend it is good, because the guys would probably be beaten up for telling the truth. The only thing that Jyian is afraid of, is his mother. Even though he usually bullied around Nobita, but sometimes he is really nice and saves the gang in the movies. Him and Suneo love to pick on Nobita, and Nobita ends up crying to Doraemon. Doraemon will always have a way to get back at them though.
