Space Paranoids

Space Paranoids is a world within Hollow Bastion's computer in Kingdom Hearts II. It is based on the Disney movie Tron, 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, the other being 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 in 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 escorts them to the Pit Cell, where Tron is being held prisoner by the Master Control Program; this room also hosts the Moogle Shop. After explaining 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.

Kingdom Hearts II
Sora wished to unlock Ansem's computer files to find any information they can on Organization XIII or Riku. Stitch fell into the scene from the top of the wall onto the keyboard, causing Donald to heatedly pursue the alien by jumping on the keyboard. Unfortunately, this alerted the MCP, and warned the party not to touch another button. Since Donald is on the keyboard and accidentally steps on more buttons, 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. They join forces, and escape. Tron tells the company about his plans to stop the MCP, and Sora tells him that they are 'Users' from the real world.

The gang venture to a city in Space Paranoids, where they confront a group of Heartless who are wrecking havoc with the 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 Seven Princesses of Heart) and returns to Space Paranoids.

Before meeting Tron, Sora and co. are forced to play on Sark's Game Grid. After a few Light-cycling games, they manage to escape and meet up with Tron. (Sora's Light Cycle oddly resembles the type of Light Cycle in Tron 2.0) The gang then go to Dataspace to insert the password, but once the 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 to get contact with 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 escaped from the Game Grid, the quarret headed towards the I/O Tower, where the data to derezz the MCP, known as the MCP Eradication Program, awaited them (thanks to the help of Leon and Aerith). After saving it onto Tron's Identity Disk, they board a Solar Sailer that awaited them outside the tower and headed towards the MPC.

During the flight, a bunch of Heartless attacked the quarret (Tron knew that the MCP would not just "let them waltz in"), causing it to overload and begin to fall off its beam, but Sora and that quickly took care of them.

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 Eradictation Program that Tron obtained back at the IO Tower. After the battle, Tron suddenly began to act all chearful, causing Sora to remark that he has a silly side (as Yuffie would later put it, one reason behind the sudden emotions was because Tron was "hanging out with the trio too much"). Before Sora and that leave, Tron says goodbye with a hug to each of his friends (Goofy remarked that it's a promise that they'll 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 their 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 Anti Form, and the circuits follow the colors of the Kingdom Hearts outfit for Limit Form - silver torso, red pants and yellow shoes.

Mini-games

 * The Light Cycle mini-game is unlocked after Sora completes it for the first time.

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.
