Kingdom Hearts 3D: Dream Drop Distance
After freeing himself from Mickey's Stopza spell at Where Nothing Gathers, Young Xehanort knocks aside Mickey and confronts Riku, summoning his Keyblade for the first time before fighting Riku in the Sanctum of Time. After his defeat, Young Xehanort de-summons his Keyblade and takes his seat amongst the Thirteen Seekers of Darkness.
Kingdom Hearts III
In the Toy Box, after Young Xehanort captures Buzz Lightyear, Young Xehanort summons his Keyblade in order to block Sora, Donald, and Goofy's attack, but unfortunately allows Woody to free Buzz while he is distracted. Once Buzz is freed, Young Xehanort pushes the trio away with his Keyblade before taking his leave, but not before making a cryptic remark to Sora and summoning a massive Heartless to combat them.
Later on near the conclusion of the Keyblade War in the Keyblade Graveyard, Young Xehanort uses his Keyblade to battle against Sora, Riku, and Mickey alongside Ansem, Seeker of Darkness and Xemnas atop the Tower of Endings. After being defeated, Young Xehanort de-summons his Keyblade before fading away, returning to his original time period.
While Sora, Donald, and Goofy combat the replicas of the Thirteen Seekers of Darkness in Scala ad Caelum, one of the replicas uses Young Xehanort's Keyblade in order to represent Young Xehanort.
Young Xehanort's Keyblade incorporates elements of the No Name and The Gazing Eye Keyblades. The tip of the Keyblade is modeled after a stopwatch, while the teeth are diamond-shaped spikes that are connected by a blue and black web structure. The Keyblade's neon blue shaft and blade resembles the Ethereal Blades that Young Xehanort wielded during his boss fight in Kingdom Hearts Birth by Sleep Final Mix and the shaft of the No Name. In addition, the demonic head and wings found on the head and the shaft of the Keyblade respectively resemble the ones found on The Gazing Eye. Like the No Name, the Keychain found on the Keyblade is an hourglass.
