Keller is a minor character in TRON: Uprising.
Keller, a scientist, developed a mind-control technique for General Tesler, incorporating the effects of a haze of pathogenic code together with signals from a tall tower. When Tesler used the technique to brainwash programs to worship Clu, Keller told him she'd created the code to give programs freedom and wanted out, but he informed her that she would either complete the technique or be derezzed, and assigned Pavel to ensure her compliance. Pavel scoffed at her science, which he did not understand, but suggested that they celebrate together as programs in Argon Square fell under the influence of the gas. Keller disdainfully retorted that she'd have to be under the influence of the pathogen, and Pavel said that that could be arranged.
When Beck, in his guise as the renegade, broke into the airship from which the viral haze was spreading, Keller used Pavel's light staff to attack Pavel and knock him out, saying that she'd really needed to do that. She escaped as the airship crashed into the signal tower, ending the effects of her virus on the population. On the run after Tesler put a price on her head, she stopped in a light rail station and used an injection to change her surface render to that of a male program, creating a disguise with which to escape detection.
- Keller may be named after Sister Mary Kenneth Keller, the first American woman to earn a PhD in Computer Science, one of the developers of BASIC, and founder of the computer science department at Clarke College in Iowa, which she directed for twenty years.
- Keller is the first character in the TRON franchise to undergo an apparent change of gender.
