!! Kevin Flynn (JeffBridges)
[[caption-width-right:267:"Greetings, programs!"]]
A former programmer at ENCOM whose ideas for video games were stolen by Dillinger. Dillinger subsequently fired him from the company to silence him. When we meet him, Flynn has spent at least a year seeking evidence of Dillinger's theft, with no success. Alan and Lora enlist him to help them put an end to Dillinger's abuse of power, but the MCP responds to their efforts in a way none of them could have predicted.

* ActionSurvivor: When he gets zapped in, he has ''no'' idea what the hell he's doing, essentially bouncing from one IndyPloy to the next and hoping it works.
* AudienceSurrogate: He learns about the Grid at the same time as the viewers.
* DeadpanSnarker: A major snarker:
-->'''Flynn:''' I never should have written all those tank programs.\\\
'''Flynn:''' Now ''that'' is a ''big door''!
* DidNotGetTheGirl: [[spoiler:Broke up with Lora before the film, and briefly kisses Yori]].
* GodInHumanForm: As a User to the programs.
* HeroicSacrifice: [[spoiler:Thinks jumping into the laser will cause this, but it simply rematerializes him back into reality]].
* HollywoodHacking: Though his methods aren't too unrealistic compared to other examples. Sitting at Lora's terminal, he was getting ready to put the MCP into a logic loop so he could search for his file uninhibited. Had he not been sitting in front of the digitizing laser, he might have succeeded.
* JerkWithAHeartOfGold: Mercilessly trolls Lora and Alan when they come by to help him out. (Lora clearly got fed up with his shtick ages ago.) Between the films, he has a bad habit of taking his friends and allies for granted. However, it's never done out of malice, and he's very willing to risk his life or even give it for his loved ones if it comes down it it.
%%* LastKiss: [[spoiler: With Yori]].
* ManChild: He seems to have regressed to this state after getting kicked out of his company. When we first see him, he's the owner of an arcade and wowing his teenage customers with his virtuoso game skills. His office overlooks the arcade, and when he asks Alan about Lora's personal bedroom habits, Lora (his ex) shouts in frustration "Now, you see why all his friends are fourteen years old!"
* MasterOfUnlocking: Has a talent with electronic locks among his various skills and uses it to open the huge main door at ENCOM.
* MessianicArchetype: From the programs' perspective he is a literal divine being who descends from on high, joins the fight against evil, and [[spoiler:returns to his own world by sacrificing himself to save program-kind]].
%%* NerdsAreSexy
* PlayfulHacker: His opening scene is trying to hack into Encom, and his orders to Clu 1.0 indicate he's used his computer skills for a few unsavory purposes.
-->''"This isn't just sorting out my phone bills or my bank statement again, this is serious."''
%%* SarcasmMode: He's usually never ''off'' this mode.
* TheresNoPlaceLikeHome: although his goals do eventually shift from "get home" to "free the system".
* TrappedInAnotherWorld: Ends up physically [[TeleportersAndTransporters digitized]] into {{Cyberspace}} by the DeusEstMachina Master Control Program.

!! Alan Bradley (Bruce Boxleitner)
One of the programmers at ENCOM, with big nerdy glasses and a hot-air popcorn machine, he created TRON.

* TheChessmaster: A downplayed and benign form of it. He had been constructing Tron for ''months,'' right under the noses of Dillinger and Master Control, while maintaining good relations with Walter Gibbs, the only one who outranked Dillinger. He had also been sending Dillinger regular memos on the project, which Dillinger promptly ignored. By the time Dillinger and Master Control realized what Tron was capable of, [[OhCrap it was far too late.]]
** ChessmasterSidekick: He becomes this to Flynn once the plan is in place to break into Encom, and between the films, becomes the man who put Flynn's big ideas for Encom into practical reality.
* GlassesPull: When he's complaining to Lora about Dillinger and the MCP.
* GreenEyedMonster: Part of the reason he was not inclined to help Flynn at first is because of Lora's past with him.
* NerdGlasses: His large and unflattering spectacles.
%%* NerdsAreSexy
%%* NiceGuy
* OnlySaneMan: Appears to consider himself as such compared to Flynn and Lora.
* ShoutOut: To Allen-Bradley, a brand of computer equipment.
** Also to Alan Kay, a computer software pioneer, and co-writer Bonnie [=McBird's=] husband
* SourSupporter: He isn't thrilled with the idea of helping his fiancee's ex-boyfriend, at least at first.
* ToBeLawfulOrGood: He's very much on the fence about ''warning'' Flynn, much less helping. The "lawful" option would be to look the other way, let Flynn get caught, and give up on his software. The "good" option involves about a half-dozen felonies for all the right reasons. He takes the "good" option.

!! Ed Dillinger (Creator/DavidWarner)
The CorruptCorporateExecutive responsible for the Master Control Progam, and Flynn's termination from ENCOM. He is now Senior Executive Vice President thanks to his "contribution" to the company line.

* CorruptCorporateExecutive: He stole the plans for several of Flynn's games and passed them off as his own. He shows himself to be unethical and dishonest throughout the film.
* DirtyCoward: When Dillinger learns that MCP plans to hack into the Pentagon and Kremlin, MCP dissuades him from going to the authorities by threatening to leak incriminating information about him to the press. This is enough to silence Dillinger.
* EvenEvilHasStandards: Dillinger balks when MCP expresses desire to hack into the Pentagon and Kremlin.
* IdiotBall: He ran with this one, but willingly letting the MCP hack the Pentagon and Kremlin just so it wouldn't tell the world about all the programs he'd stolen will forever be one of the classics.
* {{Jerkass}}: His demeanor is arrogant, he passes off Flynn's games as his own, and he hints that he could fire Gibbs after Gibbs criticizes him.
* MyGodWhatHaveIDone: [[spoiler:Reacts this way when he learns the full extent of the MCP's plans.]]
* OhCrap:
** He has one when Alan informs him that Tron would be able to watchdog Master Control. As soon as Alan's out of earshot, Master Control seems to share the sentiment.
** Dillinger also gets this when the MCP casually mentions that it plans to take over both [[TheGreatPoliticsMessUp the Pentagon and the Kremlin]].
** {{Downplayed|Trope}} at the end of the film [[spoiler:after Flynn's documentation of Dillinger's plagiarism is displayed on his desk screen, and he realizes his game is up. He says nothing, but the look on his face is enough]].'
* OhCrapSmile: {{Downplayed|Trope}} during his "talk" with Alan right after Alan drops the bombshell that, yes, his software will run independently. And oh, yes. Said software ''can'' disable Master Control. Dillinger slaps on his best fake smile, says [[BlatantLies "sounds good"]] and hustles Alan out of the office ASAP.
* SmugSnake: Despite his arrogance, he's not nearly as in control as he thinks he is.

!! Lora Baines (Cindy Morgan)
One of the programmers at ENCOM, specializing in laser research and digitizing objects. Also the current love interest of Alan Bradley, and the former love interest of Kevin Flynn.

* DefrostingIceQueen: Towards Flynn by the end of the first movie.
%%* HotScientist
* IceQueen: Flynn halfheartedly accused her of acting like this before they broke up; he may or may not [[DeadpanSnarker have been serious]].
* SweaterGirl: Wears a white angora sweater at the end of the movie.
* [[TheMissusAndTheEx The Mister and the Ex]]: Alan as the Mister, Flynn as the ex.

!!Walter Gibbs (Barnard Hughes)
An ENCOM scientist. Gibbs founded ENCOM, originally running it out of his garage, before Dillinger took over, and doesn't approve of Dillinger's methods.

* CoolOldGuy: He was the guy who founded ENCOM, but was more interested in [[ForScience scientific development]] than money. He ''invented'' the laser that got it all started. He was also the only person on-screen who dared to tear [[CorruptCorporateExecutive Dillinger]] a new one to his face over the way things were run.
* ForScience : He was so happy to be working in a lab with his laser project that he all but handed Dillinger the company he built.
* KickedUpstairs: Dillinger wanted him out of the way.
%%* NerdGlasses


!! TRON (Bruce Boxleitner)
[[caption-width-right:239:"That's Tron. He fights for the Users."]]
A security program (basically the 1982 version of a firewall), written by Alan, that threatens the Master Control Program's plans to infiltrate and take over government computers. Held prisoner by Sark as a Game Grid gladiator when Flynn first sees him.

* ActionHero: Acts as the real leader of the group as they attempt to escape, despite Flynn nominally taking charge as the only User.
* BigGood: Created by Lora and Alan to curtail Master Control's unmitigated power. He gets sent to the Game Grid to die for his efforts but is notoriously difficult to kill.
* BruiserWithASoftCenter: Yes, he's the biggest badass in {{cyberspace}}. He's also a very loyal and sweet guy. He's visibly shaken when it looks like Flynn and Ram were killed. When he's running through the city, an urgent call from his User pending, he goes to rescue his girlfriend first (and if you believe that DeletedScene, go back to her place for a while). His KingdomHearts incarnation is even more so.
* CombatAndSupport: He handles combat. Yori handles support.
* DorkKnight: Yup. Badass in a combat arena and a completely earnest, sweet-natured ''dork'' when the discs aren't flying.
* EstablishingCharacterMoment: TRON's Badass cred is established in his very first appearance, where he is seeing taking on four other Programs in a blatantly-unfair disc duel...''and wins.'' Then he raises his disc to the sky, as if dedicating his victory to the Users.
* FriendlySniper: Is an expert at throwing his disc.
* MeaningfulName: TRON means "trace on," similar to his functions in the game. Also abbreviated from "electronic."
* NameTron: According to Lisberger, TRON is a shortening of the word elec'''TRON'''ic. He didn't learn until years later that there was a BASIC command that was also TRON (a debugging tool, short for "trace on"). [[note]]The computer graphics were calculated on a small mainframe, Digital Equipment Corporation model PDP-10. That 36-bit computer has a TRON instruction (Test Right half, set to Ones, skip if any were Nonzero). Trivia: the numeric value for that opcode, in octal, is 666.[[/note]]
* ReligiousBruiser: Bordering on ThePaladin. He explicitly states that he fights for [[TheMaker Users]], particularly his creator, Alan. Much of the reason he was sent to the Games was because he refused to abandon that faith. [[spoiler: It's probably dimmed significantly come the TronUprising era]].
* ThreeLawsCompliant: Will not injure a User, or by inaction allow Users to come to harm? Check. [[spoiler: This is a big plot point in the sequel]] Obeys orders given by Users unless it comes into conflict with the first law? Check. Will fight to preserve his own life ''unless'' it comes into conflict with the first two directives? [[spoiler: Check, and tragically so]].
* TronLines (Imagine that): Blue, with a large T on his chest made of light squares.

!! Master Control Program (voice of Creator/DavidWarner)
[[caption-width-right:185:"End of line."]]
The BigBad. An artificially intelligent program used by Dillinger to advance his career at ENCOM by assimilating the functions of all the other programs on their mainframe. It eventually begins planning to take over other systems, like the U.S. Military's computers, and even overcomes Dillinger's control. Inside the computer world, the MCP is a totalitarian dictator attempting to stamp out even the belief in users.

* AIIsACrapshoot: He's a sentient program who kills other programs and seeks control of the Pentagon and Kremlin. He figures he can run things 800 to 1200 times better than any human.
* BadBoss: He inflicts pain on Sark whenever Sark disappoints him or shows trepidation.
* BigBad: The main antagonist of the film who rules his network with an iron fist, and plans on expanding to others.
* EvilSoundsDeep: His voice is a baritone version of Dillinger's.
* FlatEarthAtheist: Is not one himself, but promotes the attitude among the programs.
* AGodAmI: This appears to be his main motivation (see AI Is A Crapshoot). After derezzing and absorbing the energy and functions of too many programs to count, he sees himself as hundreds of times more intelligent and efficient than a human being could ever hope to be.
* GoKartingWithBowser: Even though he hates Flynn, he tries to talk him out of destroying him by reminding him of all the times they played Chess together.
* HugeHolographicHead: And the UncannyValley is Grand Canyon deep, emphasizing what undiluted NightmareFuel he is to the programs. Although upon his final defeat, [[spoiler: the holographic walls come down to reveal his original true form- an incredibly aged chess program whose face slowly fades out, as Dumont had noted prior; see InstantAiJustAddWater entry.]]
* InstantAIJustAddWater: Started as a chess program, then various people gradually rewrote it to perform sysadmin duties on its own hardware. After this, it continued to gain intelligence by assimilating other programs' code into itself.
* LudicrousPrecision
-->'''MCP:''' There's a 68.71 percent chance you're right.\\
'''Dillinger:''' Cute.
* NayTheist: Although his public position on the matter is less NayTheist and more "[[FlatEarthAtheist Users don't exist]], period".
* NeverFoundTheBody: The last we see of the MCP is an old man furiously typing on a keyboard, then disappearing into the darkness. WordOfGod hinted it was a SequelHook.
* OrcusOnHisThrone: Zig-zagged. MCP is adept at navigating the world's computer systems, setting the Kremlin and Pentagon as his next targets. In cyberspace, however, he's physically limited to the building he inhabits and to Sark's interface on board the carrier. He relies on underlings to carry out his will and monitor the day-to-day operations of his world. In the movie's climax, [[spoiler:Sark has to physically defend MCP against Tron. MCP can only raise shields around his base to defend himself.]]
* RedEyesTakeWarning: He appears to Sark as a multifaceted face with red eyes.
* SinisterGeometry: He appears to Sark as a digital, multifaceted face. His true form is a rapidly rotating cylinder with a humanoid face.
* TurnedAgainstTheirMasters: Intends to hack into the Pentagon and take control of the US's missile defense system, using it to force the world to obey.
* VerbalTic: When finishing conversations, the MCP says, "End of line."
* WeUsedToBeFriends: Unless what he says was a lie, this piece of dialogue implies it.
--> '''MCP:''' You shouldn't have come back, Flynn.
--> '''Flynn:''' Hey hey hey, it's the big Master Control Program everyone's been talking about.
--> '''MCP:''' Sit right there, make yourself comfortable. Remember the time we used to spend playing chess together?
* WrongGenreSavvy: He isn't overly arrogant toward the threat Flynn poses to him, but he still insists on making him fight until he dies in the gaming grid... until he escapes with Tron and Ram.
* YouWillBeAssimilated: Kills programs and takes on their functions.

!! Commander Sark (Creator/DavidWarner)
TheDragon to the MCP, with Dilinger's face and voice. Runs the gladiatorial games.

* AttackOfTheFiftyFootWhatever: [[spoiler:Sark becomes a giant after the MCP transfers all its functions to him]].
* AwesomeButImpractical: [[spoiler:Sark might be terrifying in his giant form, but he's also slow and lumbering.]]
** YMMV on the impractical: [[spoiler:Sark demonstrates his power by deflecting Tron's multi-striking disc ''with his bare hand''. If not for Flynn's intervention, it's entirely possible Tron would have lost.]]
* BadBoss: Sark is insulting and violent to his subordinates.
* BloodKnight: He's delighted when MCP gives him new victims to compete against in the Game Grid. MCP even admits that Sark is "brutal and needlessly sadistic", which Sark takes as a compliment.
* BoomHeadshot: [[spoiler:During Sark's battle with Tron, Tron's disk slices off the top of his head, exposing his brain.]]
* TheDragon: He is the MCP's right-hand man.
* EyeLightsOut: [[spoiler:When Tron's disk slices through his head, his eyes go dark.]]
* {{Jerkass}}: Even moreso than his user, Dillinger. Sark is arrogant and cruel toward everyone except the MCP.
* NayTheist: But pretends to be a FlatEarthAtheist for agitprop purposes.
* RobotsEnslavingRobots: Sark is essentially a ''kapo'', lording over the other programs while MCP lords over him. He carries out MCP's will by forcing his fellow programs to engage in gladiatorial games.
* SizeShifter: [[spoiler:In the movie's climax, Sark grows to giant size after MCP transfers his power to him.]]
* WeCanRuleTogether: He offers Tron a place by his side.

!! CLU (JeffBridges)
One of the programs Flynn used to hack into the ENCOM system.

* DefiantToTheEnd: [[spoiler:Basically spits at the MCP as he's slowly being drained.]]
* HollywoodHacking: An actual hacking program, albeit a custom one.
* MachineMonotone: Unlike almost all of the other programs. Granted, he was the only one from a different system.
* NotAsYouKnowThem: Following the events of the movie, CLU was rebuilt and vastly upgraded into a powerful Admin program who later became the BigBad of the [[Film/TronLegacy sequel]]. Some fans consider them the same character because they have the same name and actor, but they have very distinct functions and characterization.
* SacrificialLamb / SacrificialLion: To prove that the MCP is a jerk
* ScreamsLikeALittleGirl: When he crashes his tank. [[spoiler:And while being derezzed.]]

!! Yori (Cindy Morgan)
A program written by Lora. She appears to be a 3D simulation program and may play a role in the digitization process.

* AcePilot: Pilots a solar sailer to help Tron and Flynn escape.
* TheChick: Definitely the emotional anchor for the group inside the Grid.
* ChuckCunninghamSyndrome: Is never mentioned in any media after the first movie, director Joseph Kosinski assured fans that she's alive and well during the events of ''Film/TronLegacy''.
* CombatAndSupport: She isn't a warrior. That's Tron's job. However, she handles diplomacy (getting Dumont to help), piloting (building and flying the Solar Sailer), and some of the planning (the deleted scene)
* TheEngineer: She designed the Solar Sailer that gets them out of the city and most of the way to the fight with Master Control.
* LastKiss: With Flynn as he jumps into the beam.
* LingerieScene: Cut from the final release, but seen on DVD. She waits for Tron at her place while wearing a loose nightgown and basically a circuitry and glitter onesie.

!! Ram (Dan Shor)
An actuarial program for an insurance firm conscripted into the gladiatorial games. An ally to Tron and eventually Flynn.

* ActionSurvivor: Basically acts as point man for the group while they wander the outlands.
* BadassBookworm: Ram seems pretty damn good at the gladiator games he was forced into despite being an actuarial program with no security features.
* GoOutWithASmile: After realizing Flynn is a User.
* MrExposition: He gives Crom, and by extension the audience, the low-down on the MCP's regime and the game grid.
* NiceGuy: Imagine a friendly neighborhood insurance agent who genuinely loves his job helping people. He might be the most uncorruptable guy in the whole franchise.
* SacrificialLion: [[TooCooltoLive Just to piss us off.]]

!!Dumont (Barnard Hughes)
A Tower Guardian who is nearly killed by the MCP for trying to help the heroes communicate with the real world.

* CoolOldGuy: He was the one who allowed Tron to get in contact with Alan via his tower and download the upgrade that eventually destroyed Master Control. [[TheDragon Sark's]] forces eventually catch him, and he's remarkably snarky and sarcastic to them, even in the face of certain de-rez.
* DefiantToTheEnd: Insults the MCP even while being tortured.
* ObiWanMoment: Sark's troops storm the gates of his tower, intending to arrest him and drag him to certain de-rez. He calmly (but sarcastically) addresses Sark as just another Program seeking communion with a User.
* TurbulentPriest: Guardians serve a priest-like role in the system, and he maintains the last free tower. He's cranky and embittered for a good reason, but he's just fine with being a pain in the ass.

!!Crom (Peter Jurasik)
A banking program conscripted into the games.

* JewishAndNerdy: He has a pronounced New York Jewish accent and is essentially a pencil pusher.
* SacrificialLamb: To prove that the Game Grid is truly dangerous

A binary digit resembling a compound of dodecahedron and icosahedron, Bit can only say "yes" or "no" when asked a question, and is used by other programs for advice.

* BigNo: Says "No no no no no" when scared.
* BigYes: Says "Yes yes yes yes yes" when amused.
* DeadpanSnarker: Despite only being able to say "yes" and "no."
* LivingPolyhedron: Changes between a light blue icosahedron and a stellated dodecahedron when idol. Changes to a yellow octohedron when saying yes or a second stellation of an icosahedron when saying no.
* OhCrap: Bit gets this when it realizes that Flynn's about to crash his Recognizer.
* RobotBuddy: Basically follows CLU around for comic relief.
* VerbalTic: Only says "yes" and "no."
* ZeroesAndOnes: Acted as a sidekick to the hero and could only say "yes" or "no" (with a corresponding shape-change).
