for TRON: Uprising
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.
Alan Bradley (Bruce Boxleitner)
One of the programmers at ENCOM, with big nerdy glasses and a hot-air popcorn machine, he created TRON.
- Glasses Pull: When he's complaining to Lora about Dillinger and the MCP.
- Nerd Glasses: His large and unflattering spectacles.
- Nerds Are Sexy
- Nice Guy
- Only Sane Man: Appears to consider himself as such compared to Flynn and Lora.
- Sour Supporter: He isn't thrilled with the idea of helping his fiancee's ex-boyfriend, at least at first.
- To Be Lawful or Good: 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.
The Corrupt Corporate Executive
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.
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.
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.
- Cool Old Guy: He was the guy who founded Encom, but was more interested in 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 Dillinger a new one to his face over the way things were run.
- For Science! : He was so happy to be working in a lab with his laser project that he all but handed Dillinger the company he built.
- Kicked Upstairs: By Dillinger.
- Nerd Glasses
TRON (Bruce Boxleitner)
"That's Tron. He fights for the Users."
A security program, 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.
- Action Hero
- Big Good
- Bruiser with a Soft Center: 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 Deleted Scene, go back to her place for a while). His Kingdom Hearts incarnation is even more so.
- Establishing Character Moment: 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.
- Friendly Sniper: Is an expert at throwing his disc.
- Meaningful Name: TRON means "trace on," similar to his functions in the game. Also abbreviated from "electronic."
- Name Tron: According to Lisberger, TRON is a shortening of the word elecTRONic. 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
- Religious Bruiser
- Supporting Protagonist
- Three-Laws Compliant: Will not injure a User, or by inaction allow Users to come to harm? Check. 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? Check, and tragically so.
- Tron Lines (Imagine that): Blue, with a large T on his chest made of light squares.
Master Control Program (voice of David Warner)
"End of line."
The Big Bad
. 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.
- A.I. Is a Crapshoot: Figures he can run things 800 to 1200 times better than any human
- Big Bad
- Evil Sounds Deep
- Flat Earth Atheist: Is not one himself, but promotes the attitude among the programs.
- Huge Holographic Head: And the Uncanny Valley is Grand Canyon deep, emphasizing what undiluted Nightmare Fuel he is to the programs.
- Instant A.I., Just Add Water: 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.
- Ludicrous Precision
MCP: There's a 68.71 percent chance you're right.
- Nay-Theist: Although his public position on the matter is less Nay-Theist and more "Users don't exist, period".
- Serkis Folk: Quite possibly the (primitive) Ur Example.
- Sinister Geometry
- Turned Against Their Masters: Intends to hack into the Pentagon and take control of the US's missile defense system, using it to force the world to obey.
- Verbal Tic: "End of line."
- We Used to Be Friends: 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?
- Wrong Genre Savvy: He isn't overly arrogant toward the threat Flynn poses to him, but he still insist in making him fight to Death in the gaming grid... until he escapes With Tron and Ram.
- You Will Be Assimilated: Kills programs and takes on their functions.
to the MCP, with Dilinger's face and voice. Runs the gladiatorial games.
One of the programs Flynn used to hack into the ENCOM system.
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.
- Ace Pilot
- The Engineer: She designed the Solar Sailer that gets them out of the city and most of the way to the fight with Master Control.
- Last Kiss: With Flynn as Flynn jumps into the beam.
- Lingerie Scene: Cut from the final release, but seen on DVD.
Ram (Dan Shor)
An actuarial program for an insurance firm conscripted into the gladiatorial games. An ally to Tron and eventually Flynn.
Dumont (Barnard Hughes)
A Tower Guardian who is nearly killed by the MCP for trying to help the heroes communicate with the real world.
- Cool Old Guy: 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. Sark's forces eventually catch him, and he's remarkably snarky and sarcastic to them, even in the face of certain de-rez.
- Defiant to the End
- Obi-Wan Moment: 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.
- Turbulent Priest: 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.
- Jewish and Nerdy: He has a pronounced New York Jewish accent and is essentially a pencil pusher.
- Sacrificial Lamb: 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.
