Virtual Twilight Town
The virtual Twilight Town was a false Twilight Town created by DiZ as an attempt to keep Roxas contained while throwing off Organization XIII. It contained every nook and cranny of the real Twilight Town, but had some glitches, as the Seven Wonders of Twilight Town prove.
In Kingdom Hearts II
Roxas had been programmed to believe that he had grown up in Twilight Town, and had three best friends; Hayner, Pence, and Olette. The four of them had tried to go to the beach, but because the Virtual Town had no data for the beach, DiZ made Riku steal the munny away, so they could not afford the ride. Roxas had been plagued by strange dreams from another boy's memories. (These nemories belonged to Sora.) Apparently, Organization XIII had learned to hack in, and dispatched Roxas' best friend, Axel, to retrieve Roxas. Earlier, Roxas had learned about the Keyblade and wielded it against Dusk and the Twilight Thorn. When Axel told him he was going to bring Roxas to headquarters "conscious or not", Roxas defeated him. After learning more about his origins and defeating Axel one more time, Roxas was summoned by DiZ who told him that this world was simulated, used only to convert Roxas to data and awaken Sora. Roxas gave in, and Sora was awakenend within the real Twilight Town.
Much later, Sora, Donald, Goofy and King Mickey would return to this world, and use the dark portal Axel had to invade the World That Never Was.
