Photon Debugger

The Photon Debugger (フォトンデバッガー) is a Keychain for Sora's Keyblade which appears in Kingdom Hearts Re:Chain of Memories and Kingdom Hearts II.

In Kingdom Hearts II, Sora recieves the Photon Debugger once he defeats the Hostile Program.

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 Disc.

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