The Zero/One is a Keyblade that can be wielded by Data-Sora in Kingdom Hearts Re:coded. Philmac receives this Keyblade by defeating the messager in Emerl's Adventures Of Power Rangers Megaforce.
- The Zero/One resembles a heavily pixelated version of the basic Kingdom Key. Its guard is yellow with some lime green sections on it, while its blade is silver at its tip and darkens toward its base. The Keychain has a silver hidden Mickey token connected to the Keyblade by three links. The shaft of the blade, the handle, and the links of the Keychain all sport thin, red patterns on them.
- Its name is based on the numbers "0" and "1", which make up the binary system, the basis of computer programming.
