This article covers notable characters of the Tron franchise, including its various cinematic, literary, and video game adaptations and sequels.
In Tron: Legacy, which is set twenty years after his disappearance in 1989, his son, Sam, reunites with him in the Grid and he seemingly dies after sacrificing himself to defeat Clu 2.
While searching for the stolen data, the Master Control Program captures and absorbs him, using the information he gained against Flynn as he attempts to escape the game grid on a light cycle.
Tron, code number "JA-307020", is a security program that Alan created in his likeness to monitor communications between the MCP and the real world.
Lora Baines (portrayed by Cindy Morgan) is a research engineer at ENCOM and one of Gibbs' assistants, as well as Flynn's ex-girlfriend and Bradley's current girlfriend.
Yori is an input/output program that Baines created in her likeness to handle the creation of digital simulations, such as the Solar Sailer, and assist with the derezzing procedure.
Walter Gibbs (portrayed by Barnard Hughes) is the founder of ENCOM, where he and Baines work as scientists and helped develop the digitizing laser.
After learning of Flynn's investigation into his plagiarism, Dillinger authorizes the MCP to tighten security controls, but it threatens to expose his actions after he questions its intent to defy his plans of capturing other programs from government facilites like The Pentagon.
The Master Control Program (MCP) (voiced by David Warner and portrayed by Barnard Hughes) is the main digital antagonist of the first film.
Empowered by Dillinger and seeking information, power, and control over other corporations and governments, it steals data from other systems before Flynn and Tron destroy it.
Kleinberg also appears in the short film "The Next Day," included on the Blu-ray edition of Tron Legacy, which reveals his name.
Ram is an actuarial program that Kleinberg created in his likeness to "work for a big insurance company" before being captured by the MCP and forced to play on the Game Grid.
Crom (portrayed by Peter Jurasik) is a compound interest program that full branch managing savings and loan bank programmer Mr. Henderson created in his likeness.
Mercury (voiced by Rebecca Romijn) is a female humanoid computer program, known within the digital world as a champion lightcycle racer.
Ma3a (voiced by Cindy Morgan), short for Math Assistant 3 Audio, is a female computer program who is similar in personality to Lora, who improved her from Yori.
After Jet defeats them and pushes them out of the digitizing stream, as their corrupted state would have killed them in the real world, they are stored in a hard drive so Alan can fix their code.
Quorra (portrayed by Olivia Wilde and voiced in video games by Erin Cottrell) is a skilled warrior and the last remaining member of a group of "isomorphic algorithms" destroyed by Clu 2.
Programmed with the command of creating a "perfect system", Clu 2 grew to resent Flynn, particularly his fondness for the "imperfect", spontaneously-generated Isos, or "isomorphic algorithms".
Castor (portrayed by Michael Sheen) is a supermodel program and the owner of the End of Line club in the tallest tower on the Grid.
However, though Clu 2 seems to agree to the bargain, he traps Castor in his club, setting off explosions that kill him and his associate Gem.
Rinzler (portrayed by Anis Cheurfa, voiced by Bruce Boxleitner) is a security program that serves as Clu 2's right-hand man.
Throughout Legacy, he has several encounters with Sam, culminating in an aerial pursuit during which he remembers his true identity and turns against Clu 2 before falling into the Sea of Simulation.
Director Joseph Kosinski chose the name during a working session with the writers when one of Rinzler's books happened to be on the table.
In Tron: Uprising, he and his friend Hopper join a task force that Paige formed to hunt down the renegade after witnessing workers standing up to Pavel.
In Tron: Legacy, he demands to Castor that Zuse have an audience and later fights the Black Guards when they attack the club, but is derezzed.
When Sam releases the software for free, Dillinger attempts to defuse the situation by suggesting that the company take credit and claim that it was a gift to their customers.
Tesler does not hesitate to derezz his men for their failures and dislikes Dyson, as well as failing Clu should the Renegade free Argon and the Grid.
Dyson was once a friend of Tron and member of his security force until half of his face was derezzed when he tried to stop a riot between programs and ISOs.
