Dual Disc

The Dual Disc (デュアルディスク) is a Keychain for Sora's and Riku's Keyblades that appears in Kingdom Hearts 3D: Dream Drop Distance. It is obtained after clearing The Grid.

Design
As its name implies, the Dual Disc is comprised of two large discs. The upper disc which forms the teeth is based on an Identity Disk, while the grip bears a resemblance to the baton used to form a Light Cycle. The Keyblade's color scheme is reminiscent of The Grid's overall aesthetic, being a black keyblade with neon blue accents. The Keychain is a Tron LEGACY-era Identity Disk attached by a cordlike neon chain.
