Dumont is a minor character in the film Tron.
Role in the film
Dumont is a Tower Guardian charged with protecting the ENCOM mainframe's I/O Tower. He resembles his user, ENCOM founder Walter Gibbs, and has a similar closeness with Yori that Gibbs had with her user, Lora Baines.
During Master Control's tyrannical reign, his is the last free I/O tower on the system, and bitterly remarks that he is only kept around in case one of Master Control's henchmen needs to interact by the outside world. He is nearly crippled by despair by the time Tron and Yori arrive at his tower, seeking contact with Tron's user, Alan-One. Dumont is skeptical of their odds of success, saying that he has seen "many promises, many brave plans." In the end, however, he acquiesces, allowing Tron into the sanctum to commune with his user and download the upgrade to his disc. Afterward, Dumont delays Sark and his forces long enough for Tron and Yori to escape, sacrificing himself in the process.
Dumont is captured and tortured by Sark and Master Control, but the elderly Guardian remaines defiant and remarkably sarcastic to his tormentors, taunting Sark by saying he remembers when the mighty MCP was a mere chess program, and saying that the MCP "started small and would end small." Eventually, he and many other Guardians are marched into Master Control's citadel, drained nearly to the point of de-rez. Tron rescues him and the other Guardians, and Dumont stands by Tron and Yori's side at the end, overjoyed at the new freedom of sweeping the system.
- He is paid homage to in Tron: Legacy, and its viral, through the shipping company called Dumont Shipping. It was named by Kevin Flynn upon taking over ENCOM and his son Sam resides in a converted Dumont shipping container, which contains a fully furnished apartment.
- In the prologue for the graphic novel, Tron: Betrayal, Dumont says that MCP was Kevin Flynn's finest creation. This is false, because MCP was created as a chess program by Dumont's user, Walter Gibbs, and was later upgraded and modified by Ed Dillinger.
