Young Xehanort's Keyblade

Young Xehanort's Keyblade (青年ゼアノートのキーブレード) is a Keychain for Master Xehanort's Keyblade, appearing in Kingdom Hearts 3D: Dream Drop Distance.

Kingdom Hearts 3D: Dream Drop Distance
After Mickey Mouse casts a Stopza spell to aid Riku in rescuing Sora from Xehanort's Organization XIII, Master Xehanort's soul overrides the spell by possessing and temporarily granting Young Xehanort the ability to wield his Keyblade, though he does so with this specific Keychain. Riku, however, defeats him and sends him retreating, and this Keyblade is not seen again.

Design
Young Xehanort's Keyblade is a fusion of No Name and Master Xehanort's Keyblade.

This Keyblade significantly resembles No Name, in that it is predominantly colored in different shades of blue and is decorated with elaborate, spiked shapes. The tip is modeled after a stopwatch, while the teeth are diamond-shaped spikes that are connected by a black web structure similar to the design on the base of the top spire of Memory's Skyscraper. The Keychain shares the time theme represented in the blade, with an hourglass as its token. Like Young Xehanort's Ethereal Blades, the shaft resembles the weapons and the blade features an ever-present glow.

The Keyblade also includes elements from Master Xehanort's Keyblade, such as the demonic wings at the beginning of the shaft, the horned demon head at the end, and the eye of darkness.
