This paper toy is a chibi Jean Pierre Polnareff, one of the major characters in Part III: Stardust Crusaders, and makes a further appearance later on in Part V: Vento Aureo (stories of the Japanese manga / anime / video game series JoJo's Bizarre Adventure), the papercraft was created by smilerobinson.
Jean Pierre Polnareff went with Jotaro and Joseph to get revenge for his sister, who was raped and murdered by a man with two right hands.
Polnareff is the stereotypical "good-natured klutz". He is heroic and protective of those he loves, but is not very bright. He is very impulsive and loud, and is quick to jump into action without considering the risk, character traits that have landed him in lots of trouble. However, he is sincerely dedicated to doing good, and is a good man who can watch his friends' backs. He also fancies himself as a ladies man, but his personality implies that he overestimates his actual prowess.
Out of all the characters in the series, Polnareff is the one who has the least problems showing his feelings, and he adds a lot of humor and warmth to what would otherwise be a pretty cold team. Indeed, while he may sometimes be seen as the comic relief of the series, Polnareff's companions appreciate his good nature and trust him to help them win when a tough battle arrives.
Interestingly, Polnareff's best friends during the course of the series are Avdol and Iggy, neither of whom he could stand when they first met. In fact, no character mourns the deaths of his companions like Polnareff does, and no other character is as dedicated to avenging them. [Source: wikia]
