Space Paranoids

Space Paranoids is a world that appears in Kingdom Hearts II. It is entirely contained within Hollow Bastion's computer system. It is based on the Disney movie , and is named after the video game created by Kevin Flynn in the movie. Along with being one of three worlds in the series that are contained entirely within another world, it is also one of two worlds to be based on the Tron franchise, alongside The Grid.

Space Paranoids is unlocked when you visit Hollow Bastion when its Battle Level is 28. The World is inaccessible by Gummi Ship. Instead, the player must land at Hollow Bastion, go to Ansem's Study inside the castle, and access the computer. From there, Space Paranoids can be selected as the desired destination, after which Sora, Donald, and Goofy will enter it.

Settings and Areas
After Donald accidentally transports them in, Sora, Goofy, and Donald arrive in the digital world and are promptly arrested by Sark who takes them to the Pit Cell, where Tron is being held prisoner by the Master Control Program; this room also hosts the Moogle Shop. After Tron explains the situation, the party escapes the Cell, heading for the Canyon, where they play a mini-game to unlock the terminal access. Further along and to the right is the Dataspace, where the password for the computer can be inputted.

Later on, the group delves deeper into Space Paranoids; the exit on the highest level and to the left leads to the I/O Tower: Hallway. Heading right takes the group to the I/O Tower: Communications Room, while going left takes them to the Simulation Hanger, where the Solar Sailer Simulation can be accessed. The Simulation takes the party to the Central Computer Mesa, which is the area just before the MCP's headquarters, the Central Computer Core.

Before Kingdom Hearts
Long ago, Ansem the Wise copied a computer system created by ENCOM corporation for his own computer system and renamed it Hollow Bastion OS, creating Space Paranoids. It was to be used for Radiant Garden's town maintenance and for his personal research. However, after exiling Ansem and posing as his mentor, Xehanort altered the system, reintroducing the Master Control Program, or MCP, and Sark from the original system. The dataspace, where all the systems original data was stored, was named the DTD, after the Door to Darkness, and could be accessed by a password made up from the names of the seven Princesses of Heart.

Kingdom Hearts II
During his second visit to Hollow Bastion, Sora learns from Cid and Yuffie that they have found the computer of Ansem the Wise. Wishing to use this computer's files to find any information on the Organization, Kairi and Riku, or the King, Sora heads towards the castle. Upon finding the computer, Sora roughly types on the computer, vainly searching for information. While doing so, Goofy notices a blue creature on the ceiling. The creature falls onto the keyboard, and Donald jumps after him. As Donald jumps around on the keyboard, the erroneous keystrokes alert the MCP, who warns the party not to further misuse the console. While trying to get off the keyboard, Donald accidentally steps on more keys, resulting in the party being "arrested" and transported into Space Paranoids.

When the gang landed on Space Paranoids, they appear to have digital armor replacing their normal attire. They meet Sark, who sends them to a cybernetic prison: the Pit Cell. Here, they find Tron locked up as well. Tron explains how they are in a mainframe computer system, one meant to be used for processing data. Tron says while this program is a copy of the original program created by ENCOM, and that another user uses it for town maintenance and personal research. The two join forces, and escape. Tron tells the company about his plans to stop the MCP. Tron also observes that Sora, Donald, and Goofy are 'Users' from the real world.

The gang venture to the Canyon, where they confront a group of Heartless who are wrecking havoc with the energy core system. After defeating them, Tron acquires a way to send the gang back to Hollow Bastion. Before they leave, he tells them that they need the DTD (Door to Darkness) to access the data files. Sora learns the password, the names of the Seven Princesses of Heart, and returns to Space Paranoids.

Before meeting Tron, Sora and company are forced to play on Sark's Game Grid. After a few light-cycling games, they manage to escape and meet up with Tron. It is important to note that Sora's Light Cycle oddly resembles the type of Light Cycle used in Tron 2.0. The gang then go to the Dataspace to insert the password, but once access is gained, the MCP attempts to take control of everything in it. Tron hacks into the system and changes the password to the names of Sora, Donald, and Goofy. They then depart to the I/O Tower, where the MCP has summoned the Hostile Program to "derezz" (delete) Tron and Sora. They fight the program and defeat it. Tron later uses the device in the tower to return the trio to the outside world.

Sora, Donald, Goofy, and Tron unlocked the files, but learned that the data files have become corrupt. Space Paranoids, though, would be at peace for a while.

In the second part of Space Paranoids's story, when the Battle Level is 42, the MCP is shown tampering with the defense systems of the town, and releasing dangerous data-based Heartless into Hollow Bastion. Cid and Merlin are forced to work together on a system that would derezz the MCP for good. They tell Sora to head over to the computer, and before he and his friends enter, Leon tells them that any attempt of contacting Tron has failed, and he suspects that the program has been put into the Game Grid. Once they rendezvous with Tron, they were told to head towards the IO Tower.

Sora, Donald, and Goofy enter the computer once again and meet up with Tron on the Game Grid, swarmed by an army of Heartless. After they escape from the Game Grid, Tron reveals that the MCP is preparing to launch an all out war against the outside Users. Sora tells Tron of a program data created by Cid, Leon, and other outside friends, known as the "MCP Eradication Program," that could derezz the MCP. However, such a program is located at the I/O Tower. The quarret heads towards the I/O Tower. After saving the data onto Tron's Identity Disk, they board a Solar Sailer waiting for them outside the tower and head towards the MPC.

During the flight, waves of Heartless attacked the quartet, ordered so by the MCP, causing the Solar Sailer to overload and begin to fall off its beam. Thanks to the efforts of Sora, the Heartless are defeated, allowing the Solar Sailer to proceed.

Soon, the party reached the MCP, who then sent Sark to dispose of them, but he was quickly defeated. Feeling threatened, the MCP gave all his functions to Sark, which caused him to enlarge, but they were both quickly defeated thanks to the MCP Eradication Program that Tron obtained back at the I/O Tower. After the battle, Tron suddenly starts acting cheerful, causing Sora to remark that he has a silly side; Yuffie later blames his personality change on Tron "hanging out with the trio too much." Before Sora, Donald, and Goofy leave, Tron says goodbye with a hug to each of his friends, each promising to see each other again one day, before jumping into the core where the MCP once stood.

Sora, Donald and Goofy exit the system, where it is revealed that the Heartless invasion has stopped. As they try to explain on what happened, Tron suddenly speaks to them, now in control of the Hollow Bastion OS. He then shows what the town used to be like before it was destroyed, leading everybody to remember the true name of the town: Radiant Garden.

Character Design
In Space Paranoids, Sora, Donald, and Goofy, are converted into data and change forms accordingly. While one can vaguely tell what colors they were in the physical world, they all have a heavy blue tint. When Sora changes into his Drive Forms, the circuit patterns on his outfit alter color to match according to the form: they will change to red for Valor Form, blue for Wisdom Form, yellow for Master Form, white for Final Form, black/purple for Antiform, and the circuits follow the colors of the Kingdom Hearts outfit for Limit Form - silver torso, red pants and yellow shoes.

Trivia

 * The world-icon for Space Paranoids features several Recognizers pursuing a pair of Light Cycles, portraying a scene in the film where Kevin Flynn, Ram and Tron escape the Game Grid. No Recognizers appear in Kingdom Hearts II outside of the world-icon, although they appear in The Grid in Kingdom Hearts 3D: Dream Drop Distance.
 * Tetsuya Nomura originally intended for Space Paranoids to return in Kingdom Hearts 3D: Dream Drop Distance as part of Sora's story, while The Grid was only meant to be for Riku, though Nomura eventually scrapped the idea and used The Grid for both characters.
