This article covers notable characters of Tron and its various cinematic, literary, and video game adaptations and sequels.



For the first film, Richard Rickitt explains that to "produce the characters who inhabit the computer world, actors were dressed in costumes that were covered in black-and-white computer circuitry designs....With coloured light shining through the white areas of their costumes, the resulting characters appeared to glow as if lit from within....optical processes were used to create all of the film's computerized characters..."[1] Frederick S. Clarke reports that "Tron 2.0 will combine live action with CGI," adding that "several characters...will be completely digital..."[2]

Main characters



Bit is a character from the movie Tron. Representing a bit (binary digit), it was only capable of providing yes or no answers to any question. Despite this it still managed to convey emotion and other levels of complexity.

Physically, Bit was represented within the movie by a blue polyhedral shape that morphed between the compound of dodecahedron and icosahedron and the small triambic icosahedron (the first stellation of the icosahedron).[3] When "at rest" this shape was constantly shifting. When the Bit announces the answer "yes" it briefly changes into a yellow octahedron, and when it announces "no" it changes into the 35th stellation of the icosahedron, colored red.

Bit appeared twice in the movie, once at the beginning of the movie as a companion to Flynn's hacking program Clu and once later on as a companion to Flynn himself when he stole a Recognizer.

Bit was originally to have a more extensive role in the film, but it was cut to just two minutes due to scheduling reasons.[4] Despite this, the co-creators of Max Headroom, in their book Creative Computer Graphics, called it "one of the most memorable characters in the film."[4] At the time of the film's release, the character represented an innovative use of computer graphics techniques such as vector graphics[4] and morphing.[5]

In Tron 2.0, a redesigned Bit is known as Byte, who is identical and speaks in the same distorted voice. However, unlike Bit, Byte is able to speak full English.


Michael Sheen plays as Kaster, a night club owner inside the Tron world.[6]

Master Control Program

The Master Control Program (MCP), voiced by David Warner, is the main villain of the movie. It was a rogue artificial intelligence created by Dr. Walter Gibbs(as a chess program) that ruled over the world inside ENCOM's mainframe computer. During the rule of the MCP, many programs were enslaved and forced to play games against its henchmen, led by Sark (also played by Warner). To gain information and power, as soon as Ed Dillinger was promoted due to the video games he pirated from another programmer's file, the MCP immediately began to blackmail Dillinger into doing his bidding.

Dillinger used the MCP to administer the company's computer network (in effect an AI Superuser). However, the MCP had the capacity to learn and grew beyond the confines of its original programming. It began to steal data from other systems, and took control of several companies and institutions. Its intelligence - and ambition - grew nearly out of control, and the MCP grew to desire nothing less than world domination; stating "From here I can run things 900 to 1200 times better than any human."

Eventually, however, the MCP caused its own downfall. It digitized former ENCOM programmer Kevin Flynn, who had come dangerously close to uncovering Dillinger's schemes. Flynn, in the computer world, allied himself with Tron, a security program; their combined efforts resulted in the deresolution (death) of the MCP. The MCP then reverted back to its original chess program appearance (which, in the digital universe, appeared as an old man in a control chair) followed by this program vanishing as it was deleted.

The MCP would end most of its conversations with Dillinger and Sark with the phrase "End of line".

The MCP also appeared in Kingdom Hearts II as the ruler of Ansem the Wise's computer, and the player's final opponent in Tron's world. In the game's storyline, the MCP was rebooted by Ansem after its initial deletion, and attempted to take over the network until it was again deleted by Sora and Tron. It was voiced by Corey Burton.


Sark is an evil computer program, one of the main characters in the film Tron.[8] He was played by David Warner in said film[9] and voiced by Corey Burton in Kingdom Hearts II in a manner uncannily similar to Warner's distinctive voice.


Command Program Sark, as his guards call him, is the henchman and chief lieutenant to the Master Control Program. Both programs were created by ENCOM executive Ed Dillinger, and share Dillinger's voice (and in Sark's case, his physical form), though in the case of the MCP, this voice is much deeper. Sark oversaw the training of new programs who were kidnapped and brought to the Game Grid by the MCP. Sark freely admitted that the training he arranged for the conscripts was somewhat substandard, as Sark's own elite force of programs nearly always won every match they took part in. Sark was known to enter the games himself from time to time, and was a grand master at any game he cared to try (when we first meet him, he is victorious in a game of Light Cycles).

Sark was brutally efficient at his work. Furthermore, the MCP himself pointed out that Sark actually enjoyed his job - "brutal and needlessly sadistic", as the MCP put it. Sark took immense pride in being labelled as such.

Nevertheless, Sark and the MCP's reign of terror over the computer world quickly came to a crashing halt when Kevin Flynn, a former programmer at ENCOM, was digitized and brought into the computer world. Sark refused to believe that there was anything special about Flynn, arrogantly dismissing him as "just an ordinary program". Sark threw everything he could at Flynn in an effort to eliminate him, but Flynn (along with Tron, a security program) fought back just as hard. Sark's repeated failure to kill Flynn drew the ire of the MCP, who menacingly wondered how Sark would "take to working in a pocket calculator". After being threatened with deresolution (death), Sark resolved to wipe Flynn out once and for all. On board his command carrier (which resembles a flying aircraft carrier), Sark captured Flynn and attempted to use him to lure Tron out into the open where he could kill them both. In a battle with Tron, Sark was mortally wounded but was revived by the MCP, who infused Sark with all of his power - "Sark, All of my functions are now yours". Flynn distracted the MCP, which was subsequently killed by Tron. Upon the MCP's death, Sark derezzed and ceased to exist.

Kingdom Hearts II

In the Square Enix/Disney RPG game Kingdom Hearts II, Sark, still the MCP's henchman and now a Heartless commander, is a villain in the Tron world, Space Paranoids. Sora, Tron and company fight Sark in the MCP's stronghold, and defeated him fairly quickly, after which he suggests to Tron that they would have made a great team whereas Tron replies that he is better than Sark; however, he was enhanced by the MCP, growing to giant size and fighting Sora's group yet again with the MCP by his side. Sark's powers were dangerously brutal in his giant size, but, along with the MCP, he was defeated. After the MCP was deleted by Sora and Tron, Sark faded out and disappeared. With the exception of the extra Kingdom Hearts characters and the absence of Flynn, Ram, Yori and Dumont, this scene plays out almost the same as the film's climactic end. David Warner, who played Sark in the movie, was offered the part, but had to decline because of a previous commitment and was only able to lend his likeness to the game[citation needed]. Sark's role was instead performed by veteran voice actor Corey Burton, who gave a near-flawless imitation of Warner's British accent.


Tron, played by Bruce Boxleitner, is the titular character of the film. He is a security program created by Alan Bradley (also played by Boxleitner). In the movie, he stopped the MCP and Sark with the help of the digitized user named Flynn.

In Kingdom Hearts II, when Sora, Donald, and Goofy are digitized into Space Paranoids (the game's Tron-based world), he and friends first encounter Tron in a Pit Cell, where they all have been sent to by Sark, a Heartless commander. After helping Tron break free, they activate a power core which allows them to access the real world, allowing Sora and company the ability to pass between them. Tron revealed he is trying to access the DTD (Door to Darkness) but cannot obtain the right password since a majority of his functions were appropriated by the MCP. He sends Sora to the real world, where they find the password (Belle, Snow White, Aurora, Alice, Jasmine, Cinderella, Kairi) behind a portrait of Xehanort. Tron then hacks the DTD, gaining back all of his functions, and granting Sora access to information on the Heartless and the Nobodies. He then changes the password to Sora, Donald and Goofy to buy himself some time against the MCP, who has gained access to the DTD and decides to test the emergency destruct program for the town, while he and Sora's group travel to the I/O Tower to fight a pitched battle with a Hostile Program, which they defeat. Tron then informs the trio of Ansem's status as his user and enemy; the latter because he rebooted the MCP. It is unknown if Tron later became aware of the fact that the person who rebooted the MCP was actually Xehanort, Ansem's apprentice, or that the real Ansem eventually died at The World That Never Was.

Later, Tron is forced onto the game grid in a fight for his life. Meanwhile, Hollow Bastion is under attack by Heartless that the MCP has downloaded into reality. Sora and co. return to save Tron, and he soon learns that he has a lot of user friends: Leon, Cid, Merlin, Yuffie, and Aerith and then Cloud. They then return to the I/O Tower where Tron receives a special Eradicator program for use against the MCP. A solar sailer ride later, they arrive at the mainframe. They engage in battle with Sark. They defeat him, but he is then upgraded by the MCP, who tries to convince Tron to join it. Tron refuses, and the gang deletes the MCP. In the fight, he has a Delete Reaction Command with Sora to drain the MCP's health. In his happiness at the victory, Tron shows himself to have a "silly side." He then bids goodbye to his friends with a hug each, promising to see them again, before diving into the mainframe to take over the MCP's functions (Sora, Donald and Goofy think that Tron dived into a pit of nothingness). Back on the outside, the Heartless disappear, and Tron gives his new friends something he dug out of the archives: footage of when Hollow Bastion was first built. From watching the footage, Aerith revealed their home's real name as "the Radiant Garden."

Tron, like the other party characters, has a unique limit attack when teamed with Sora. Tron's is called "Setup", where he and Sora float on a platform and fire data at various enemies while Tron attempts to gain access to the Reprogram Reaction Command. At the end, once Tron gains access, Sora slams the reprogram button.

In the game credits, Tron is given a new program, and he can be seen dancing. This shows that he picked up his new friends' "illogical habits."


In a review of the film, Deborah Wise writes that "it is hard to believe the characters acted out the scenes on a darkened soundstage...We see characters throwing illuminated Frisbees, driving 'lightcycles' on a video-game grid, playing a dangerous version of jai alai and zapping numerous flourescent tanks in arcade-game-type mazes...If that's not enough, the characters use computer jargon to crack jokes."[10]
