Characters present in the tie-in prequel video game to TRON: Legacy, TRON: Evolution. Characters also present in the film will have their tropes from only the game listed here, instead of those in the film. For those, the film page can be found here.
The Player Character, Anon is a System Monitor who was created to stop the Basic-ISO conflicts.
- Back from the Dead: Sort of, in Tron: RUN/r. His design is the default male skin, though whether it's a somehow re-rezzed Anon or just a look-alike isn't expanded upon.
- Badass Biker: On a light cycle.
- Badass Driver: On a Light Tank.
- Deadly Disc: His only weapon, though it has several variants.
- Heavy Disc: His basic disc, this allows for hard hits, but not much else.
- Bomb Disc: This allows for explosions on impact, knocking enemies aside or derezzing Light Tanks.
- Stasis Disc: This allows Anon to slow down targets.
- Corruption Disc: This allows Anon to siphon health from enemies.
- Mag Disc: A gift from Quorra, this allows him to grapple across certain points.
- 11th-Hour Superpower: Kevin Flynn super-upgrades Anon prior to the seventh and final chapter, turning his circuitry white and making him powerful enough to try a one-program assault on the Rectifier.
- Everyone Calls Him "Barkeep": Everyone in the game simply calls him "The System Monitor", with his actual name Anon coming from supplementary materials.
- The Faceless: His helmet never retracts.
- Featureless Protagonist: Aside from being male, we don't know much about him.
- The Hero Dies: Crushed by wreckage from the Recognizer.
- Hero of Another Story: In TRON: Legacy, Quorra mentions that a "sympathetic program" helped her to escape the Purge before she was found by Flynn. Anon is that program and this is that "other story".
- Heroic Sacrifice: Throws Quorra off of the broken Recognizer in the finale, being crushed and killed under it instead.
- Heroic Mime: More extreme than normal, he doesn't even have reaction efforts.
- Le Parkour: Anon uses parkour to navigate through Tron City, Arjia City, and the Bostrum Colony. Parkouring is even integrated into the combat system to enchance attacks.
- Meaningful Name: He's meant to be "Anonymous" so that players can identify with him and put themselves in his place better.
- One Program Army: Anon is always outnumbered by CLU's forces and the Infected Programs but never stops tearing through them. He's even more this after Flynn upgrades his disk for the final attack on CLU's command ship.
- The Voiceless: Doesn't speak at all. Not even damage grunts.
- Voiced By: Kari Wahlgren
An Alpha-class program who is the leader of the ISOs, Radia is trying to develop ties with the Basics to ensure peace when the Abraxas virus hits.
- Reasonable Authority Figure: She gives both Quorra and Anon advice about how to stop CLU when they give evidence of his treachery.
- Voiced By: Jensen Ackles
A sarcastic Bostrumite, Beta-class ISO program who helped to save Kevin Flynn when he escaped CLU 2.0 during the rebellion. Anon seeks his aid on how to find The Maker.
- Badass Biker: Has a light cycle.
- Badass Bookworm: He was a very intelligent member of the system utilities sector before being forced out by Fantastic Racism. He's still able to manipulate and conserve very large quantities of energy.
- Boss Banter: Mostly begging to be derezzed.
- Deadpan Snarker: Almost every line he says is sarcastic.
- Dying as Yourself: He even thanks Anon before derezzing.
- FaceMonster Turn: And Then Gibson Was An Infected
- Fighting from the Inside: He's not particularly good at it, but he does manage to beg Anon to kill him when Infected, which is more than many others can say.
- Heroic Sacrifice: Crashes his light cycle into Anon's to get him away from Abraxas and take the fall for him.
- I Cannot Self-Terminate: When infected.
- In the Hood: Wears a hoody and no shirt.
- Mercy Kill: What he begs for.
- Mr. Fanservice: Until his infection.
- No Shirt, Long Jacket: Wears a hooded trench coat similar to Abraxas.
Abraxas a.k.a. Jalen
- Voiced By: John Glover
A virus who is infecting the Tron System. Really Jalen, an ISO who was "killed" in the Game Grid. He was reprogrammed by CLU 2.0 as a virus to serve him in his war against the ISOs.
- Actually, I Am Him: Wordlessly. Radia was shocked to see his identity as Jalen before he killed her.
- Badass Longcoat: Wears a trench coat with a hood that obscures his face.
- Big Bad: Subverted. He was advertized as such, but Clu's (once again) the guy that's ultimately responsible.
- Brainwashed and Crazy: What his virus does, turning circuits yellow on program suits and making them into pseudo-zombies. Also what happened to he himself, due to CLU 2.0.
- Darth Vader Clone: Has a cape-like trench coat, breaths like he grew up in an asbestos mine, and has a quasi-religious bent to his destruction. He's also second in command to the real Big Bad.
- Deadly Disc: Like many, he has his own Identity Disc, unique among the infected in that he uses one.
- Expy: His character design looks a lot like "Master User" Thorne of TRON 2.0, and they serve the exact same plot function; a living virus that seeks to corrupt and destroy everything in his path and who is just an Unwitting Pawn to the truly diabolical masterminds behind it all.
- FaceMonster Turn: His backstory.
- Final Boss: Unsurprisingly, he's the final fight of the game.
- Final Boss Preview: In the introduction, though it works a lot differently in the end.
- The Heavy: Created by CLU to cause havoc, and he's good at it.
- Hero Killer: Kills Radia.
- Hoist by His Own Petard: CLU's own creation returns to take revenge for his torment, destroying CLU's command carrier. CLU, himself, escapes, but Abraxas's intervention create the opportunity for Anon to rescue Quorra, and provides cover for his eventual death.
- Implacable Man / The Juggernaut: Illustrated when an entire level is dedicated to running away from this guy.
- In the Hood: On his Badass Longcoat
- Names to Run Away from Really Fast: Named for a supernatural entity of great power.
- Puzzle Boss: You have to attack the energy cores as he attempts to power himself up. He is otherwise far too strong for Anon to damage, even upgraded.
- Rogue Protagonist: Supplementary material confirms that Jalen is the player character of TRON: Evolution: Battle Grids. That said, going rogue was not his idea.
- Skilled, but Naïve: Jalen was noted to have been a brilliant architect and engineer within the System, having designed and built Arjia City himself, and was skilled enough in the Games to win a championship tournament. His naive trust of Clu and his offer of a "disc upgrade", however, results in horrific consequences for himself, his people, and the Grid in general.
- Touch of Death: He infects any program he touches.
- Tragic Villain: He's not initially evil (if you listen to Jalen's voice diary clips in the collectible Abraxas Shard extras he was apparently rather sweet). He's just driven to insanity by CLU's manipulation.
- That Man Is Dead: "Jalen is gone. It's Abraxas now."
- The Slow Walk: He never runs in the entire game, chasing you across the place like Jason. It works.
- Villainous Rescue: His assault on CLU's carrier provides the cover necessary for Anon to rescue Quorra.
- The Virus: In a literal sense. He infects programs and corrupts them into deranged lunatics like himself.
- Walking Wasteland: His footsteps leave sickly yellow scars in the ground during cutscenes.
- Unflinching Walk: Quite frequently. In particular there's his opening scene, where he kills three defense programs without breaking stride.
- Voiced By: Nolan North
A gaming program, he fights in the Game Grid.
- Bald of Evil: Though he's probably not evil, he does give off the impression.
- Irony: "This is gonna hurt. A lot." Cue Recognizer death.
- Voiced By: Olivia Wilde
A strange girl who aids Anon on his mission. Her tropes can be found under the TRON: Legacy page.
- Distressed Damsel: Captured by CLU 2.0 in Chapter 7.
- Grappling-Hook Pistol: Her Mag Disc, which she also gives to Anon.
- Living MacGuffin: By the end of the game, Kevin sends Anon back not only to stop the virus, but to save her.
- Voiced By: James Frain
A Basic program who runs the ISO-friendly club known as the End Of Line Club. His tropes can be found under the TRON: Legacy page.
- Voiced By: Bruce Boxleitner
Anon's superior, he appears in the introduction before he is shifted off for the events of the film. His tropes can be found under TRON: Legacy.
- Voiced By: Fred Tatasciore
- Badass Biker: His light cycle, a 2nd Generation, is the fastest on the Grid.
- Badass Pacifist: By the sounds of his talk of murder on the Game Grid, which he designed to be nonlethal this time around.
- Physical God: Of the Grid.
- Super Empowering: Upgrades Anon's disc before the last mission.
- Voiced By: Fred Tatasciore
- Big Bad: Everything traces straight back to him, including the Abraxas Virus.
