An example of an Identity Disk
- "Everything you do or learn will be imprinted on this disc..."
- ―Sark, explaining the Identity Disk's primary function.[src]
Identity Disks (I.D.) or also known as a light disc are weapons used in the Disk Arena for combat. They have two main uses in combat: blocking an incoming attack or as a thrown projectile weapon. If a direct hit is scored on the opponent, they will instantly be derezzed.
Identity Disks are also used to record everything that a program of the Tron Universe sees, does or learns. Identity Disks have the same color as their owner's circuitry.
Variants
There are several variants of the Identity Disc, called the Sequencer the Cluster Disc, and the Charger Disk. These seem to be made of more shards. The sequencer is made of several pieces, and allows the player to throw from 3 to 6 disks at once. The cluster is made of the same pieces in a larger radius. When it's detonated it releases several deadly shards. The Charger Disk allows players to pick up weapons and upgrades from a distance.
Trivia
They are now more commonly referred to as Light Discs outside of the films and canon. The upgraded version of the Identity Disc features a sleeker design with lit edges, rather than many lit circles on the surface. As a result, they are faster than the original models.
In Tron Legacy, when Sam Flynn copies the Grid onto a computer chip, it has a component on it that resembles the first identity disk.
The Identity Disk featured in the first film looked like (and probably was) a regular, off-the-shelf frizbee, with multiple circles drawn on it.
