He is the opposite of Suneo in many ways, for instance, Nobita's son, Nobisuke, bullies him. He is afraid of Nobisuke like Jaichibi. He probably inherited his good heart from his grandfather and his uncle. He is naive and innocent. He dislikes bragging about his riches. He was still shown to be arrogant, insulting Mini-Dora as a cheap robot.
His hair is somewhat longer than Suneo's, but he has the same eyes, nose, hairstyle and fox face.
