This papercraft is a The World bust, the stand of Dio that is featured primarily in Part III: Stardust Crusaders of a Japanese manga / anime / video game series JoJo's Bizarre Adventure, the paper model was created by StormL. The World along with Dio's second stand awakened post-assimilation with Jonathan Joestar's body. There is also a Star Platinum Bust Papercraft at PaperCraftSquare.
The World resembles Dio in several ways; it has a tall muscular body and the same green heart motifs. Its feet also look exactly like Dio's shoes. It also bears watch motifs on the back of each hand, symbolizing its power to stop time. Its head is shaped like a mask with a triangular top that somewhat resembles the crowns of ancient pharaohs. Another detail is the two lookalike oxygen tanks on its back.
The World has never shown any personality, but in Part VI: Stone Ocean, it was hinted that if not for Dio's own personality, it would go out of control. It represents the Tarot Card The World, which symbolizes triumph, perfection and absolute fulfillment.
Dio mentions that unlocking the stand enabled the Joestar descendants to obtain similar abilities, due to it originating from Jonathan's body.
The World is similar to Jotaro's Star Platinum with its phenomenal strength, senses and stamina, but has a bigger range of use and is less durable to compensate. Its main form of attacking is to perform a sequence of punches while yelling Dio's battle cry "Muda Muda Muda!"
Time Stop: The World's defining power is its ability to stop time, allowing only itself and Dio to act within the duration of stopped time. Given Dio's weakened state during Part III, this ability only works for a few seconds in Dio's frame of reference before time flows again. However, also due to Dio's immortality, the duration of stopped time also increases as Dio becomes more accustomed to The World, reaching a maximum of nine seconds. The only way to counter this skill is with other time-manipulating skills. [Source: wikia]
