The World

Personality/Appearance
The World get it name from the Tarot card, the World. The World resembles Dio Brando in many ways, having a muscular yellow body, when Dio wore yellow clothing and even the same green heart shape emblem on it's chin, which Dio wore around his head. It seems to have a several cogs and mechanical tubes coming from it back and a time devise resting in both hands, symbolizing it power to control time. It has never shown any personality. However in Stone Ocean it was hinted that if not been for Dio's personality it would go out control.

Powers
The World (世界 (ザ・ワールド) Za Wārudo), very similar to Jotaro's Star Platinum, is a Stand with phenomenal strength, senses and stamina - but is also faster and more accurate. It can also stop time (for a longer duration as well). He also has at least a measure of Joseph's psychic abilities (specifically, the ability to create a vision on a photograph). A possible explanation for the fact that The World has psychic powers that are only used once is that Hirohiko Araki (the creator of the manga) implied for it to have the power of all of the Stands, or possibly the power of the Stands of the Joestar lineage, due to Dio inhabiting the body of Jonathan Joestar. It's implied in Part 6 that he wanted to use his Stand to create a perfect world for himself and a handful of subordinates. He enlisted Enrico Pucci as his living "conscience", in case he would go crazy and be "off track".
