Tron

Tron is a program who aids Sora in Space Paranoids, a world based on the 1982 Disney film . He appears in Kingdom Hearts II.

Kingdom Hearts II
Tron meets Sora, Donald, and Goofy while they are trapped in a Pit Cell with them in the mainframe of Ansem the Wise's computer. After escaping the cell and enabling access back to the real world, the four companions proceed to find a way to unlock the D.T.D., Ansem's dataspace. After activating a power core, Tron sends Sora and the others back to Hollow Bastion to locate the password required to access the D.T.D. They locate the password behind a large painting of Xehanort (thanks to Tifa moving it aside), the password being the seven names of the Princesses of Heart. Tron hacks into the D.T.D and changes the password to Sora, Donald and Goofy, to bide himself time before the MCP attacks again. Sora, Tron and the others reach the I/O Tower where they fight a Hostile Program, which they defeat.

Tron reveals to the three that Ansem is his user, but explains that Ansem also rebooted the MCP, suggesting that this may have been the doing of Xehanort, who had stolen Ansem's name prior to becoming a Heartless and Nobody.

During the group's return visit to the mainframe, Tron has been forced onto the Game Grid to fight for his life, while Hollow Bastion is being overrun by digitized Heartless by the corrupted town defense mechanism. Sora and the others save Tron and he learns all the Hollow Bastion residents are supporting him. Cid creates an Eradicator Program to stop the MCP's threat for good, which Aerith later passes on to Tron at the I/O Tower. Using the Solar Sailer vehicle to reach the core of the mainframe, Tron, Sora, Donald, and Goofy battle Sark and easily defeat him, but the MCP retaliates by reviving and upgrading Sark, commanding him to battle them and protect him. After a furious battle, the MCP is eventually deleted and Sark along with him. Tron is overjoyed and shows off his "funny side" to his friends, whom he hugs in a term of goodbye, before jumping into the core to take over the MCP's functions. He locates an old footage of Hollow Bastion when it was first built that reminds everyone of its former name, Radiant Garden.

It is not known whether Tron learns the truth about Xehanort having been the actual person to activate the MCP but under the stolen name Ansem, especially since Sora learned this by the time of his return trip to Space Paranoids.

Sometime after Xemnas's defeat, Tron apparently downloads other software and happily dances back to the dataspace.

Appearance
Tron resembles a normal adult human male, albeit with light blue skin and covered from head to toe in grey armor. Tron's armor is mostly seamless, the only distinct parts being his knee-high boots, small pauldrons, and what appear to be "sleeves" that cover his forearms only, not his upper arms or hands. He also wears a helmet vaguely reminiscent of a. Tron's armor is covered in complex patterns of blue computer circuitry that glows bright cyan at times. A similar glow emits from his boots and "sleeves".

Though most of the circuitry designs are seemingly random, certain patterns on his waist and helmet create the silhouette of a belt and parts of the human brain, respectively. His eyes are grey, as are his eyebrows, suggesting that his hair, if he has any, is also grey. It seems that Tron carries his Identity Disk on his back, or at least has a circular plate resembling it on his upper back.

Personality
As in the film, Tron is shown to be a noble, selfless being who would stop at nothing to fight for his friends and justice. Despite his sometimes serious exterior, he is shown to have a playful side, demonstrated by when he hugs Sora, Donald and Goofy before he merges with the computer system, and when he is shown to be ticklish. After Xemnas's defeat, Tron is even seen to be dancing.

Abilities
Tron is a conservative, ranged-focused party member, wielding his Identity Disk, which has even lower power than Donald's staves. He only has one accessory and armor slot, and two item slots. In battle, Tron typically keeps his distance and attacks opponents via range by throwing out his weapon like a boomerang until it flies back into his hands

Prior to accessing the DTD, Tron's skill set is limited to three support abilities: Item Boost, Jackpot. and Auto Change.

After accessing the DTD, his AP increases and he gains a number of new abilities. This includes another support ability, Auto Limit, and his set of action abilities, which include a far-ranged attack, Scouting Disk, and Pulsing Thunder, the equivalent to the regular Thunder spell. His limit, Complete Compilement, is an incredibly powerful attack, compensating for his weak weapon.

After entering the computer for the final time, Aerith activates the rest of Tron's support abilities: Thunder Boost and MP Haste.

Fight against the MCP
During the final combat with the MCP, Tron is required to be in the party to derezz it. While Sora can break the MCP's defense walls, he requires Tron's presence to insert the Eradicator Program into the MCP's core. The Reaction Command of this move is called "Delete", and it is only available in this battle.

Origin
Tron first appears in the 1982 film, Tron, where his role is basically the same as in the game. In the film, however, he is assisted by several supporting characters such as Kevin Flynn, Yori, Ram and Dumont in his battles against Sark and the Master Control Program. He was written by Alan Bradley as a security program to monitor the Master Control Program. As in the film, he uses his identity disc to critically injure Sark and derezz the Master Control Program during the final battle. His ultimate fate is left unrevealed in the movie, but it is known that he survived in order for Flynn to copy him onto his own, personal Grid.
