Simulated Twilight Town
The Simulated Twilight Town is a world that appears in Kingdom Hearts II, and makes a brief appearance in Kingdom Hearts 358/2 Days. It is a false Twilight Town created by Ansem the Wise as an attempt to keep Roxas contained, while also throwing off Organization XIII. It was created using the same technology Ansem used in Radiant Garden's Space Paranoids, and can be entered by similar means. It is a nigh-perfect recreation of the real Twilight Town, as it has some glitches in the form of the Seven Wonders of Twilight Town. Ansem even recreated every resident of the town, using data samples of each person's heart in the real town. Although keeping to their usual attitudes, they do mostly act under Ansem's influence, though he is unable to completely control them.
Kingdom Hearts 358/2 Days
After Sora, Donald, and Goofy's journey through Castle Oblivion, Ansem the Wise, operating under the alias "DiZ," convinces Naminé to move the trio to his lab in Twilight Town to protect them from Organization XIII, as the castle was still under their control. However, in order to restore Sora's memories completely, Ansem sends Riku to capture Sora's Nobody, Roxas. Once Riku returns with an unconscious Roxas in tow, Ansem placed Roxas inside the Simulated Twilight Town in order to hide Roxas from the Organization until it was time for Roxas to return to Sora.
Kingdom Hearts II
To prevent Roxas from escaping, DiZ altered Roxas' memory with data to make him believe that he was a normal teenage boy who lived in Twilight Town with his best friends Hayner, Pence, and Olette. In spite of that, Roxas begins experiencing strange dreams of Sora's exploits during his first adventure. In the digital Twilight Town, summer vacation is coming to a close, and Roxas and his friends try to have some last-minute fun before returning to school. Unfortunately, his fun is constantly being interrupted by strange white creatures and two men in black coats. One of the cloaked men, Axel, was sent into the digital Twilight Town and attempted to persuade Roxas to return to the Organization. When Roxas showed no signs of remembering either his friendship with Axel or his time with the Organization, Axel resorts to violence to bring him back, "conscious or not." As time goes on, Roxas begins to regain his memories of the Organization, with the help of the Keyblade and Naminé, who acts as a guiding figure to Roxas.
Everything Roxas knew began to crumble around him, and he could only trust Naminé. On his last day in Twilight Town, Ansem freezes time inside the simulated realm and summoned Roxas to the Old Mansion outside of town. Roxas enters the mansion and witnesses Ansem and the other cloaked man capturing Naminé. Roxas then obtained her drawings, identical to one on the library table, and draws Sora's crown necklace in one of the three circles on the table. After completing the symbol, Roxas gains access to Ansem's computer room. There, he finally regained his full memory, remembering that he was once a member of Organization XIII, who had used him for his ability to wield the Keyblade, and that he had left it to find his past, only to be captured by Riku.
In his rage, Roxas destroys the digital version of DiZ's computer, then fights with Axel one last time in the simulated mansion's basement, before merging with Sora. Sora then awakens from his year-long sleep in the real Twilight Town.
The virtual Twilight Town was first visited by Sora late into his fight against the Organization. He enters the virtual Twilight Town with the help of Hayner, Pence, Olette, and King Mickey. Sora enters a portal left by Axel in the virtual basement of the mansion to access The World That Never Was.
