Photon Debugger

The Photon Debugger is a Keychain for Sora's Keyblade that was introduced in Kingdom Hearts II.

Design
The Photon Debugger looks similar to the inhabitants of Space Paranoids, appearing to be constructed of computer circuitry. The Keychain's token is Tron's Identity Disk.

Its name comes from two words; debugging is a way to eliminate a computer virus or bugs, similar to how the Keyblade eradicates Heartless. Photons are the fundamental quantum particles that compose light, and Sora is the wielder of the Keyblade of Light.
