A Bit is a binary digit associated with a program. In the real world, a bit can be stored by a digital device or system which can carry information by existing in one of two distinct states.

Bits are represented by bluish-white polyhedral shapes, constantly shifting while at rest and stellating into different forms and colors when they speak. Bits can understand complex language, but are binary in nature and can only say "Yes" and "No." Though they speak monotonally, they can express intensity of emotion by repeating "No, no, no, no, no, no!" if alarmed and "Yes, yes, yes, yes, yes," if amused or excited. Bits can be affiliated to individual programs, accompanying them in their tasks and aiding them with advice or analysis.


In TRON, a Bit accompanied Clu in his tank mission; told to "get out of here!" when Clu was captured, it hid in the damaged remains of a recognizer. Encountering Kevin Flynn later, it appeared to believe that Flynn was its program, and stayed with him until they were separated when the badly-steered Recognizer crashed again.

In TRON: Legacy, models of Bit could be seen on young Sam Flynn's bedroom shelf.

In TRON: Uprising, Able keeps a Bit in his office, among other relics from the system's beginnings. When Zed berated himself for foolishly allowing Perl into the garage, the Bit annoyed him by agreeing.

TRON: Evolution introduced the NAVI (Navigational Assist Vector Information) Bit, designed by Kevin Flynn to guide the ISOs to their daily needs in Tron City while keeping them away from secured areas. As part of registration, ISOs had to have the NAVI Bit added to their discs. NAVI Bits go offline outside Tron City's limits.

In TRON: Evolution - Battle Grids, Bits are used as a form of currency. They can be picked up by players, usually hovering stationary in their "yes" shape in rows with other bits, in many various places within the Grid, and used to purchase Light Cycles, discs, and other goods.

In TRON 2.0: Killer App, Bit helps Tron during his adventures.

Bit Shapes and Colors

Digital Effects animated Bit's blue-white neutral form by morphing it in a loop from a compound of a dodecahedron and icosahedron to the seventh stellation of an icosidodecahedron and back again.

When Bit says "Yes," it transforms into a yellow/orange octahedron.

When it says "No," it turns red and morphs into the second stellation of an icosahedron.

  • Bits in the TRON universe have a neutral state, but bits in the real world do not; as binary digits, they can only exist in one of two states, positive or negative, with no neutral state in between.
  • In TRON's novelization, the Bit used multiple synonyms for "Yes" and "No," including translations of those words into various foreign languages.
  • The pre-production concept art for TRON reveals that the Bit was originally envisioned to be a sphere shape with a face over its surface, making it slightly resemble a 3-dimensional Pac-Man.
  • The fireworks in TRON: Legacy were designed around icosahedrons, dodecahedrons, and the like, in homage to the original movie's Bit.
  • Dialog in TRON: Uprising uses the word in a different context, referring to a program being derezzed "bit by excruciating bit."
  • Byte, a character from TRON 2.0, is modeled from Bit. However, instead of having only two forms, Byte can speak fluently, though monotonously.
  • There is a product on Sony's Playstation Home (PS3) allowing players to own a Bit inside of their game home. It doesn't communicate, but does perform the animations at random times.
