Photon Debugger

The Photon Debugger is a Keyblade acquired after Sora's first trip to Space Paranoids in Kingdom Hearts II.

Acquisition
The keyblade is given to Sora by Tron after the two of them defeat the Hostile Program before it could destroy Hollow Bastion.

Appearance
The Photon Debugger looks similar to the inhabitants of Space Paranoids, appearing to be constructed of computer circuitry. The key chain is a miniature version of the Data Disk used by Tron in both Kingdom Hearts II and the film, Tron.

Etymology
Its name comes from two words; debugging is a way to get rid of a computer virus: it is possible that the virus' this keyblade destroys are the Heartless. Photons are a form of light, and Sora is the wielder of the Keyblade of light.
