The World's Fair is an event wherein people from various companies and institutes present their products to an audience. However, this is not all that happens, as amusement park rides, food, and fireworks are all among the various recreational activities that take place during the event.
The latest World's Fair took place in Paris, France, at night. There, several participants, including Sonic the Hedgehog and Dr. Eggman, would enjoy their time there. Eggman's true motives, however, were to steal a new space shuttle from Thorndyke Industries that would be revealed at the fair. Meanwhile, Rouge the Bat and Topaz arrived at the fair in order to track down Eggman.
The next day, when Nelson Thorndyke was about to reveal his company's new space shuttle, Eggman interrupted the fair and unleashed his robots, forcing the fair's visitors to evacuate. Sonic and his allies soon dealt with the robots.
- The World's Fair is based on the real-life event with the same name.
